how this scam works when you participate in competitions and how to avoid it

by

Let’s explain How it works and how to avoid the scam of the false winner On Facebook. It happens when you participate in some kind of raffle in this social network, and the scammer will respond to your comment to make you believe that you are the person you have won. We are going to start the article explaining the way in which these deceptions work and some of the variants you can find. And then we will tell you how you can avoid falling into these traps. How this scam This deception works When you have participated in a Facebook contest Require you to leave a comment. You know, one of those in which you ask you to mention something or leave a comment in some way to participate. So what the cybercriminal does is answer your message saying that you have won. Will use an account in which or hide who is or directly get through the artist or entity that is doing the raffle. In your comment, it is normal for this person I leave you a link To supposedly access your prize. This link will take you to a website designed to deceive you and steal data with forms to fill out to collect your prize, and in some cases also to steal your account or steal money. This type of deception has been on Facebook for a long time, and There are several different types to those who can face. His way of proceeding is similar, but his ability to deceive yourself by making someone vary. There are some that are quite simple and easy to distinguish, but there are others in which cloning names and profile photos, and it can be easier to snack in them. In the end, with what these scammers play is with your desire to carry a contest. When you receive the notification you will see the falsified name and image image and some first words of congratulations, and that can push you to press and act in a precipitous way. How to avoid this deception The most important thing if someone responds to a comment with which you participate in a contest and tells you that you have won is Verify the information with the real account in whose publication you commented. When these raffles are made, a publication is always made announcing the winners, and if they have not done it verifies the times and how long they have given to participate. The important thing is that Don’t rush clicking on links. In fact, normally They will not tell you to tell you that you have wonjust a new publication is going to be made. Therefore, by default you should suspect these messages. Be very careful if you write to you by private message That I get to Messenger. In many cases the scammers will write you directly. Do not trust if apparently it is the same accountbecause both the name of an account and its profile image usually falsify you. In case of doubt, Contact the original account in whose publication you have commented. Tell them the message you have received, because they can confirm that it is a hoax, and you will even help them to notify the rest of the participants not to fall into these scams. In any case, the measures can be summarized in cold blood and verify the results of the contest in which you have participated. Especially cold blood, don’t get carried away by emotion.

This is how the curious creator of LG wallpapers works

by

We have moved to Frankfurt to see and touch firsthand THE NEW LG TREES FOR 2025 And by the way, try the latest version of Webos. We have found a twist more to a consolidated Operating system seasoned with great artificial intelligence. That artificial intelligence reaches televisions makes more sense than it seems and, leaving aside some profits that have been essential and other more or less useful, if there is one with a point of experimentation, creativity and fun that has caught us, that is the to generate images with AI, called Image Ai Solution (By Google). I have done my TV’s background with ia To get the best results you have to approach the command to the mouth Creating images with artificial intelligence is not something new, but it is fashionable: you have Midjourney, Dall- e3 And in general, A long list of free applications. Do it on devices that are not the computer, mobile or tablet is the order of the day, but Generate your images from TV and with voice is another story. As of tweet With your LG fridge of that teenager who went viral, but really. Why generate images with TV? LG’s response could simply be breastfeeding: ‘Because I can’, but the reality is that he has his one, for example to have a wallpaper of our family in the style of ‘The Lord of the Rings’ or simply so that the next time someone uses TV, a birthday greeting appears just on that day anniversary of his birth. Let it know that it is possible to do it by text, but The most natural and agile on a TV is to pull the voice and make use of suggestions to polish the prompt until we get what we want. For this, the new Magic Remote AI remote control has a button to invoke its AI that we must keep pressed while we talk to capture the entire phrase. This function of generation of images with AI is in beta and I tried it in English (it was ESO or Korean, it is not available in Spanish) in a living room with enough noise, which meant some problems when the remote control captured the words well. In this sense, yours is approach the command to the mouth and that the room is silent. In my evidence I started from simple concepts such as drawing a dog, a cat (we said ‘cat’ but understood ‘God’) and even something much more complex and detailed as samurais with dragon plates armor in the middle of some cherry trees. Overcome the barrier of understanding the order, The results were surprisingly good. The model used to generate images is Exaone-3.5 (whose repository is available In Github) and includes 100 free creditswhat I would give for a hundred generations. If later you would like to generate more images, the specialized engineers told us that the idea is to adopt a billing system. With these generated images, it is possible to download them to save, share them and of course, use them as a unique and exclusive wallpaper made by ourselves, an addition that makes personalization rise level and also, another way of Generate income through TV softwaresuch as integrated advertising or ads LG Channels.

Germany gets serious with nuclear fusion. His energy model shouts that this ‘Stellarator’ reactor works

by

The experimental reactors of nuclear fusion of type Stellarator They represent a very solid alternative to Tokamakas ITER either JET. And they are not precisely the result of a recent investigation. In fact, both designs were designed During the 50s of the last century. He Stellarator It was designed by the American physicist Lyman Spitzer and exercised as the foundations on which the Plasma Physics Laboratory of Princeton University (USA) was built. The design TokamakHowever, it was devised by Soviet physicists igor Yevguénievich Tamm and Andréi DMítrievich Sájarov from the ideas proposed a few years before by his colleague Oleg Lavrentiev. Both reactors were conceived with the purpose of confine Stellarator He received great support from the scientific community in the West due to its enormous potential. However, when Soviet and American scientists published their results and compared them, they realized that Tokamak design performance It was one or two orders of magnitude better than that of Stellarator. From that moment on, this last design was largely marginalized. The most obvious difference between one and the other lies in its geometry, but it is enough to investigate both to realize that the reactors Stellarator They still have a lot to say. Proxima Fusion has put a date to its demonstration fusion plant Type reactors Tokamak They have a toroid form (or donut), and Stellarator They have a more complex geometry that resembles them to a twisted donut on itself. However, the fundamental difference between these two designs is that the reactors Tokamak They require that the magnetic fields that confine plasma be generated by coils and induced by plasma itself, while in the reactors Stellarator Everything is done with coils. There is no current within the plasma. This means, in short, that the latter are more complex and difficult to build. In February 2023, the Wendelstein 7-X reactor managed In Europe we have a type fusion reactor Stellarator extraordinarily promising: el Wendelstein 7-X. It is installed in one of the buildings that the Max Planck Institute has for Plasma Physics in Greifswald (Germany), and its construction concluded in 2015. The first tests carried out in this fusion reactor between 2015 and 2018 came out as planned, so in November of this last year An important moment arrived in his itinerary: It was necessary to modify it to install a water cooling system that was able to evacuate more effectively the residual thermal energy of the vacuum chamber walls, as well as a system that allowed the plasma to reach a higher temperature. The works that required these modifications concluded successfully in August 2022. And in February 2023 the Wendelstein 7-X reactor reached an important milestone: it managed to confine and stabilize the plasma for 8 uninterrupted minutes in which it delivered a total energy of 1.3 gigajultos. During the last two years everything learned in the development and the first tests carried out in this machine has been used by the German emerging company Proxima Fusion. In fact, its founders come from the Max Planck Institute for Plasma Physics. His work is being financed by Germany, the European Union, and also by several private entities of venture capital. And it’s going very well. In fact, fusion physicists and engineers have published a scientific article in Fusion Engineering and Design which has already been reviewed by pairs and in which they detail the design of Stellaris, its reactor prototype Stellarator commercial. Your next step requires Build a demonstration power plant From its design that should be ready in 2031. Yes, in just six years. I hope you get it. If Alpha, which is what this test power plant will be called, the commercial fusion energy will be a reality before the next decade is completed. This is the authentic purpose of next fusion.

What is Amazon’s new intelligent assistant, how it works and what is its price and availability

by

Let’s explain What is Alexa+ worksthe new version of Amazon’s virtual wizard with artificial intelligence that The company has announced. It is not a simple competitor in the career of the AI ​​chatbots, but Amazon takes him to his field to offer much more. We are going to start explaining what Alexa+ (or Alexa Plus) is, what he can do and its main characteristics. And then we will tell you how it works internally, to end up talking about its price and availability. What is Alexa+ Alexa+ is a new version of the Alexa virtual wizard. The idea is to add it Artificial Intelligence Capabilities to the Assistant Alexaso it is not simply to launch a new alternative to Chatgpt, but rather to evolve the company’s assistant. Although Alexa+ will be able to answer any questions as you ask the other artificial intelligence models, their main objective is another. It is an agricultural, and His goal is to do things for you. Come on, it is still an assistant as Alexa has always been, but now much more capable of understanding what you want and performing more complex operations. This new artificial intelligence heart allows Alexa to be much more conversational. Will recognize your natural language Instead of having to use voice commands, and will also answer you in a clearer and more natural way. It is multimodal, which means that you will understand different types of orders by voice or text. But of course, Alexa is still You can interact with the home automation of your home. It is smarter, conversational, personalized and capable of doing things and completing tasks. You explain what you want, and Alexa will be able to interact with the household devices connected better by understanding your instructions. Alexa may use the devices and applications you have connected and activated to perform the tasks you ask for. You can even perform actions such as booking table in a restaurant or sending a message to your children’s kangaroo, adding these events to your calendar. But come on, the most important thing is that you know that Alexa+ is not just an alternative to chatgpt To which you will be able to ask anything, but it is the way in which Amazon uses artificial intelligence to make the existing Alexa smarter and capable. It is still a virtual assistant to perform tasks, but now with more possibilities. How Alexa+ works The new Amazon virtual assistant uses technology Amazon Bedrockwhat this does is allow him access different large language models either Llm. Among the languages ​​they resort are are the company’s own, such as Amazon Novabut also third -party models such as Claude from Anthropic among others. Amazon qualifies Alexa+ as an agnostic in terms of AI model. This means that it will not always use the same, but that will use the most useful at all times Depending on the idea we have asked to complete. Come on, first analyze what you have asked for, and then resort to the model that best suits your request effectively. In addition to this, Amazon has also associated with several media organizations for Be able to access current and truthful information and use it to answer your questions. Among the media chosen are names such as The Washington Post, Condé Nast, AP, Business Insider, Reuters, Sfgate, Pcgamer or Autoblog, among others. But as we have said, the objective is to be an agthic and be able to interact with other services to perform tasks. With this objective, Amazon has reached agreements with services and ecosystems such as Sonos, Samsung, Grubhub, Ubereats, Openable, Dyson, Vizio, Ted, Plex, Xbox or Ticketmaster, for example. This way, If you ask Alexa+ to take you tickets For a specific concert, you will be able to connect to Ticketmaster, look for that concert, look for tickets and buy them. And so with many other things. And so, also to reserve tables, buy meals, or make interactions with other services and devices. Alexa is also still, so He will continue to manage the home automation of your home. But of course, it is not the same to have to remember concrete commands for the wizard to turn on the lights to be able to ask for it with a natural language, or give it more details of what you want to get. Price and availability Alexa+ will have a price of $ 19.99 per monthand will be compatible with practically all Alexa devices that Amazon has commercialized so far. Come on, if you have a device that Alexa uses, you can subscribe to its upper version. In addition to this, Alexa+ It will be free for Amazon Prime subscribersso it will join the catalog of services that the company is offering within this unified subscription. Regarding availability, Alexa+ will initially arrive in the United States During March 2025, and It can only be used in English. It is logical to think that it will end up arriving in Europe and Spain, but the company has not yet announced dates. And taking into account the price of the service, it would not be surprising that prime upload price when doing so. In Xataka Basics | 14 Alexa’s secret commands to find games and fun hidden ways

After a delay of seven years, Saudi Arabia takes up the works of the highest skyscraper in the world. Let’s see what lasts

by

Saudi Arabia has become the Madrid of the ‘galacticos’, the Barcelona of the ‘Tiki-Taka’. When we talk about megaconstructions, the country plays in another league, a capable of shadowing the Almighty Manhattan. And it is evident when we see all those projects that have as hands like the imposing MUKAABthe huge Abraj al Bait tower watch or the ‘Boss’ end of urbanism: The Line. Another project is Jeddah Tower that, like The Line, It has been choking More than once to builders. But, after two threats to return to the work, now the final one has arrived: they have restarted the works of what will be the highest building in the world. Kingdom Tower. The Jeddah Tower, or Kingdom Tower, has an objective between eyebrow and eyebrow: make the Burj Khalifa 828 meters high. To do this, the same team of architects that built the Dubai skyscrapers is being in charge of this tower, which will be the jewel of the crown of the crown of the Vision 2030 Project and the heart of a new city that will rise around it. The construction began more than a decade ago, but although they advanced at a good pace, the planning was too optimistic. It was said that it would have been completed in 2018, but by then, the tower was not even close to completing. The reason? Delays due to labor problems and COVID-19 Pandemiabut above all to the purge of corruption of 2017. The purge. In 2018, the heir prince Mohammed Bin Salman created an anti -corruption committee with an objective: centralize political power. He had tired that different elites of the country handled the threads, so he created a system that ended with more than 380 arrests of entrepreneurs, ministers, princes and even members of his family, as his own mother. HE speak of death groups to murder dissidents and, in this purge to stop political corruption, extortion to officials and money laundering, foundations and first floors of the Jeddah Tower suffered the consequences, being frozen. Initial plans with the intention of release the tower in 2018 and a height comparison To the third is the defeated. At the end of 2023, the promoter invited local contractors to see which candidacy conquered him for the end of the work and, in October last year, a video made it clear that They moved on. The problem is that everything was very in the air … until now, when the company Kingdom Holding Companythe one behind the project has announced that construction has restarted. In it release before the press, They affirmed that they had already poured cement on the 64th floor and that they are using a cement application technique with which they can complete a floor every four days. 1,000 meters, more or less. It will have about 160 floors and we cannot speak with ownership of the matter because, really, it is not clear. It is curious that it is not known from the beginning how many floors the tower will have or how much it will measure, and in the last releaseThey explain that it will measure more than 1,000 meters high, but that it is something that will take place in the future. To every train. What seems invariable is that it will be a luxurious tower that will act as an epicenter of a new city. The skyscraper will house shops, offices, recreational spaces and hotels, such as Four Seasons. He also aspires to have the highest viewpoint in the world and is expected to be a structure covered with glass, such as an extremely elongated pyramid and with a base of three edges. It will be in an area of ​​5.3 million m² in which there will be hospitals, schools, universities, shopping centers and housing, as well as other high towers and, from the government, it has been confessed that they are open to any type of investment to develop The ambitious project. Investment? Welcome. They affirm that the financing has almost been completed, with the builders -binladin Group- financing the first part, the banks putting their grain of sand and other sources of capital that has preferred not to reveal (stating that it is something that they will do step by step). What has made it clear is that Binladin Group is “strongly supported by the government” and that they are open to any type of investment because it is a tower that will make the land around you increase their value. And not only the immediate, like that land of 5.3 million m², but the entire region. This is what they want to ride around them They have work ahead It is estimated that the Jeddah tower is completed by 2028 as part of Vision 2030 to diversify the economy of the country, but as this does not stop, they are already thinking about its following tower: one that will humiliate Jeddah with a height of two kilometers in Riadnear the imposing Rey Khalid International Airport.

How it works and how to prevent them from doing with yours

by

We are going to explain a type of fraud that has been growing more than a year, and that is being used to steal your Google accountand with it both access to Gmail and your photos or other services. It is a hoax that mixes both artificial intelligence and classic phishing, and that should be known. We are going to start the article explaining how this deception works, so you know how to recognize the way you proceed and you can upload your guard if you recognize that behavior. And then we will end up with several tips to avoid it that you should always keep in mind. How this deception works To perform this deception, cybercounts use artificial intelligence systems to make phone calls. With the AI, it seems that on the other side a real person is talking, and in this call you are told that your Gmail account has been compromised. They also tell you that they will help you. So, in the next step you are sent An email that seems to come from Google. In this email there are seemingly reliable links that take you to fraudulent pages. The idea is that you press in these links thinking that you are going to configure the safety of your account or change the password. But what you really do is Give your Google data so that the cybercriminals are left, and can access your account. How to avoid this scam To avoid these types of scams, the first thing you should keep in mind is that Google won’t call you to let you know. Simply, this company will never tell you if your email has been compromised, nor will they send you a chat to tell you. As for the emails that can reach you, Look well in the direction of the sender. Even in cases where he comes from Google as the person’s name, look at the address of the mail from which he writes to detect if they are accounts that have nothing to do with Google. Always be careful with the web pages That they arrive by mail or by message to perform procedures that include writing your account. For that, the mouse passes over a link so that the real direction to which it goes, and detect when it is an address that has nothing to do with it. In both emails and addresses, it verifies that the URL ends at Google.com or Gmail.com. Be careful if only the company’s name appears in the middle From the address, or if after the first point of the URL another word appears before the .com. Finally, in the case of having doubts Manually enter the official pages of Google or Gmail without clicking on any link, and simply change the password of your account manually.

This is how Ech works, the Technological Shield of Cloudflare that has put the operators between the sword and the wall

by

The LaLiga fight against illegal soccer broadcasts It has encountered an unexpected obstacle: Ech (Encrypted Client Hello), an encryption protocol that stars in the great conflict and the collateral damage of this battle, which splashes thousands of companies. Turning point. It all started when Cloudflare implemented in October 2023 (Encrypted Client Hello), an extension of TLS that prevents operators from identifying which specific domain is requesting the user. This protocol makes it technically impossible for operators to see which specific domain requests a user. The contrast. ECH works as an additional encryption layer that completely hides the final destination of a connection: When a user tries to access a website, his browser initiates an encrypted “negotiation” (Handshake TLS) With the server. Before ECH, although this connection was encrypted, the name of the domain was traveling “in clear” so that the intermediate servers could enrut the traffic. With ECH, the name of the domain is also encrypted, making it impossible for the operators to know which concrete website the user is accessing. The system is even more complicated because Cloudflare uses shared IPS: The same IP address can house hundreds or thousands of different websites. Without ECH, the operators could see what domain each user requested and block selectively. With ATU activated, they only see an encrypted IP that could be serving both legal and illegal content. This leaves two options to the operators: block all the IP (affecting hundreds or thousands of sites) or not blocking anything. When they choose the first thing the Blocked legitimate websites. To avoid blockages, which also translate into a reputational crisis, some operators are resorting to alternative techniques such as: Traffic patterns analysis. Deep inspection of packages (DPI). BLOCK BY SNI (Indication of the server name) when ECH is not active. But these solutions are complex, expensive and not always effective. The conflict has climbed, Movistar has softened his blockages, Digi has hardened them and Vodafone says to have a more precise solution although it has not revealed details yet (since Xataka We have asked them for this without having received an answer at the time of publishing this article). They possibly use one of the last points. The next. Ech has supposed a huge change in Internet architecture. The precedent of Austria, where IPS blockades were prohibited To protect the neutrality of the network, it suggests that the current regulation model needs to adapt to this new reality. Meanwhile, the pulse between LaLiga and Cloudflare persists, and thousands of Spanish companies also remain trapped in the midst of the conflict.

What is cloudflare, how it works and why a fall or block makes half the Internet fail

by

Let’s explain What is cloudflare and how it works This shield and accelerator for web pages. It is one of those almost essential services for the correct functioning of the Internet, but that we are not aware until it fails or blocks and you can enter hundreds of websites. We will begin this article explaining in a simple way what is cloudflare, summarizing the operation of the Internet and the role that CDNs have like this service in it. Then, we will tell you why a fall or lock of the service makes half the Internet seem to fall. What is cloudflare and how it works Cloudflare is a CDN, a Content Delivery Network either Content distribution networkthat in Spanish is Content distribution network. It’s about a network of servers distributed throughout the world destined to help better distribute Internet content and make you can quickly and safely access the content of a website. To understand its operation you must first understand how the Internet works. A web page is housed on a server, and simplifying it a lot, when you enter it you connect your computer to that server, to access the contents of a website. The same happens when you want to enter any online service or web application, you have to connect to your server. The problem is that perhaps the server of my application is in a country far from the computer from which someone wants to connect. So, that distance makes the connection speed very slow, or that even from some countries cannot be entered. The same happens if the web or the service you are going to access had a single server. Then, having thousands of users entering that single server would make everything slower because I would have to work more and for more people. It is here where the CDNs and their networks of servers come into play. When a website, an online service or application resorts to them, is as if they had copies of the content and cache distributed all over the world to be able to connect in a faster and more efficient way. There will always be a server close to you, and traffic can be distributed by the hundreds of servers. Thus, if I connect from Spain to an American service, I will not join a giant user queue wanting to enter a single server that is also far away, something that would make the connection slow. Simply, I will connect to the nearest server of the CDN network that is using that service. Everything will go faster, and the traffic that accesses the service will be more distributed. Cloudflare is one of the most used CDNs of the world. There are many web pages that resort to this company, because in addition to a very wide network of servers, it also offers protection against various types of online attacks that could collapse access to the contents. This way, Cloudflare is an intermediary between a customer or user and the content of the website or the online service they want to access. It is a network that houses copies of a service so that you always have geographically close, technologically safe access, and less traffic collapsed. Why if Cloudflare Failure Middle Internet does it When you stop accessing this network of servers, you can access its content. This means that if your Internet operator blocks you access to Cloudflare or if this service has a failure, stop being able to enter most web pages. There will be no network that distributes traffic and access to these websites, and simply connect to one would be too slow or you would be too far. For practical purposes and simplifying it a lot, Not being able to access Cloudflare means not being able to access many servicesand that those who use it and are not fallen simply go extremely slow. This is so for The dependence of Cloudflare. Being one of the most popular CDNs in the world, many important and top -level services access it. And these services that use it, depend on their servers network to work properly. In this PDF You can see the services and websites used Cloudflare, such as X, Bluesky, Microsoft, Mozilla, Snapchat, Temu, Efe, Github, Wikimedia, Facua, CaixaBank and many more. All these services will stop working or work extremely slow if the Cloudflare network stops working. When a website or online service fails, it is sure that there is a problem with the infrastructure of the server network that provides you with access to it. So Errors like the 502 Bad Gateway indicating this problem. If the one who cannot access a website, app or service is due to this, all you can do is cloudflare or the CDN to use the error. When an operator blocks access to cloudflare Or some other concrete CDN, the problem is that your IP cannot access this network of servers, although it works correctly. In these cases solving it is easyand you just have to use one VPN to access from a different IP that does not have access.

What is it, how it works and requirements to use this method to renew your DNI

by

Let’s explain WHAT IS THE EXPRESS DNIa process that is beginning to deploy in Spain to expedite the process of renewing the national identity document. This process usually takes because you have to go to the police to do it, obtaining an appointment first. But now it is starting to expedite, so that renewing the ID can be very easy and fast. We are going to start explaining what the express DNI is and how this procedure works. Then we will tell you What are the requirements To be able to use this method to renew your document, and so know if you will be able to do it. What is and how the express DNI works Express DNO is a new method for renew your fast and easy IDwhich will live with the traditional method. Instead of face to face with an agent to complete some procedures such as putting your fingerprint, you will enter a cabin where everything speeds up. It’s about A multiple expedition module (ME) that are being installed in the police stations that can perform this procedure. This means that it is not in all, but in those where the DNI is renewed, that these machines are being installed. It is a double cabin, and on the other side there are an agent who can serve two people at the same time. In it, in addition to renewing the ID at the moment you will also be able to make the payment, either by card or contactless with your mobile or smart watch. These stations have technologies for biometric capture, with which you can Remove the photo of a person and get their fingerprints. Come on, the two things that are needed for you to renew the DNI can be done in this cabin. The term DNI Express refers to the fastest process without renewal, not the identity document, so what you get is exactly the same as if you do by the traditional method. The advantage of this method is that You do not need to request a previous appointmentsomething that in some cities can have a long waiting. In addition, it reduces the costs, since You don’t need to take a picture for the ID In no establishment, the machine takes it out for you. REQUIREMENTS TO USE THE EXPRESS DNI These are the requirements that you must meet to use this new service. You have to fulfill them alland if there is any that is not fulfilled you will have to renew your document for the traditional channels: They must miss 180 days or less for the expiration of the DNI, that is, to be within their renewal period. Personal data, such as address, must be maintained. The current ID chip must be in perfect condition for the module to read it without problems. It must be a renovation and not a first expedition. In any case, such renewal should not be caused by the loss or theft of the document. The fingerprints They must be read correctly. As is evident, in addition to this it will be necessary that in the police police station where the ID is renewed in your locality, one of these cabins has been installed, something that can take a little longer in some cases.

Thanks to this table we can finally understand how metals compatibility works

by

Materials science is an exciting discipline. It is likely that some people seem unattractive, and it is a respectable opinion, but objectively it is about A very important scientific branch. Its purpose is to study the structure, physicochemical properties and the behavior of the elements with the purpose of Design new materials which can be used in a very wide range of industries. The kevlar used in The bulletproof vests and the diaphragm of some speakers, among other applications; the carbon fiber used in the aeronautical, automobile and sports industries; high performance alloys used, for example, in nuclear reactors and The turbines of the aircraft; or the Carbon nanotubes which are already being used in some electronic devices support the relevance of the science of materials currently. Rufosity matters. And a lot One of the properties that usually study material engineers is roughness. This characteristic identifies often imperceptible irregularities that reside on the surface of a material. To measure them, it is usually necessary to carry out a microscopic analysis, but the really important thing is that this knowledge allows researchers to design and manufacture new components. And it is that roughness is an essential parameter that conditions the performance, durability and applications in which a new material can be used. In fact, there are research groups and companies that are dedicated in body and soul to characterize new materials and measure their roughness. Michigan Metrology It is one of these companies. It resides, as we can intuit, in the state of Michigan (USA), and expressly dedicates itself to measurement, analysis and inspection of roughness and wear of surfaces. To carry out their analysis, it resorts to very sophisticated teams that are capable of precisely identifying the irregularities present on the surface of the materials through a three -dimensional exploration. The table we publish on top of these lines has been prepared by the American mechanical engineer Ernest Rabinowicz, and is the Bible for Michigan Metrology and other companies that are dedicated to material engineering. In fact, it is the authentic protagonist of this article. And it is because it gives us a lot of information about the roughness and sliding compatibility of a good part of the metals that we can find in the periodic table of the chemical elements. Two pieces work better together if they are metallurgically incompatible, or, what is the same, if the metals involved are not dissoluble with each other As you can see, Rabinowicz occurred to be placed on the horizontal and vertical axes of the table the symbol that identifies each metal. And at the intersection between each pair of them appears A very illustrative symbol that identifies whether these two metals are incompatible, partially incompatible, partially compatible, compatible or identical taking as reference their roughness. In the field of metallurgy this information is very valuable. And it is because metals that are compatible from a metallurgical point of view tend to adhere to each other, a process that increases friction and wear. As we can intuit, knowing precisely the degree of compatibility between each couple of metals is fundamental in the design of the sliding interface between two metal pieces. In fact, two of these pieces work better together if they are metallurgically incompatible, or, what is the same, if the metals involved are not dissoluble with each other.
