[SEMINAIRE] Big-Data analytics for materials science  - Matthias Scheffler
On the steady search for advanced or even novel materials with tailored properties andfunctions, high-throughput screening is by now an established branch of materials research. For successfully exploring the huge chemicalcompound space from a computational point of view, two aspects are crucial. These are reliable methodologies to accurately describe all relevant properties for all materials on the same footing, and new concepts for extracting maximal information from the big data of materials that are produced since many years with an exponential growth rate. The talk will address both challenges. In particular, I will present a Test Set for Materials Science and Engineering which enables quality control of rst-principles calculations .Furthermore, I will demonstrate the possibilities o ered by statistical learning theory for big data of materials. With respect to the latter I will also present the concept of the Novel Materials Discovery (NoMaD) Laboratory, a recently established European Center of Excellence: http://NoMaD-Lab.eu

Check out the official app http://apple.co/1ThDIrx Watch more How to Do Small Science Projects for Children videos: http://www.howcast.com/videos/510859-How-to-Demonstrate-Engineering-Principles-Science-Projects Hey, guys. Thinking natural disasters. When you think of natural disasters, there are several that come to mind. You have earthquakes, volcanoes, tornadoes, hurricanes. But, if I show you marshmallows, and I show you toothpicks, and tell you that we’re about to do an experiment that has to do with natural disasters, you’re gonna be, like, “Wait, what? Marshmallows and toothpicks, and natural disasters? But you.” Yeah, we’re going to do that, and I have a challenge for you. This is your challenge: I need you to get a bag of marshmallows, and you know what I love about this, is if your marshmallows ever get stale, the worst thing to do as a scientist is to throw them out. You can reuse anything, rather than making it into garbage. Now, you have a challenge, and your challenge is this, can you create a multi-story structure, a structure, I think, that people can build? So, you have to make it multi-floored, which means more than one or two, I would say. And, here’s the kick, after you build it, it has to be standing. You’re not allowed to hold it up. It has to be free-standing and stable. Stable on the table. Gravity should not be knocking it down. Then, we’re going to simulate an earthquake. So, after you’re done, and you've made this really awesome structure, made out of only marshmallows and toothpicks, we’re going to shake the table, and we’re going to make an earthquake. And you can be, like, “Earthquake.” Just tremble and vibrate. And if your structure is still standing after 30 seconds of your simulated earthquake, you, my dear, are an engineer. And check this out. Your structure’s actually gonna be three-dimensional, and all you need are marshmallows, and all we need are toothpicks. It doesn't matter if they’re the pointy type or the flat type, but, marshmallows are actually cylinder shapes. So, take a marshmallow, take a toothpick, put it through. You kinda have, it looks like you’re going to be working out with it, but you’re not. Now, think about how we can take this, and turn it into a really awesome three-dimensional shape. I’m going to start with this square, and then I’m going to build it up, and turn this square into a cube. Now I’m going to start going higher, just like this. And the beauty about this experiment is, a bag of marshmallows is so inexpensive. Toothpicks, pretty much anybody has toothpicks at home. And, I can learn so many amazing concepts of engineering, building, gravity, center of gravity. You see, you really want this structure to have this amazing centered gravity, so that, If you really think about it, gravity’s always trying to knock you down. In fact, unfortunately, when we get a little older, you start to lean forward, because in your lifetime, your body has done nothing but battle gravity. Which is why our backs arch as we get older. But, now look. I just made a three-dimensional cube. This is exactly one floor high. But the challenge is, could you create multi floors. And, as you get it to go higher and higher, it has to be stable. Stable on the table. You do not want it to be not balanced. The rules are you’re not allowed to hold it up. This is a challenge. And you’re only allowed to use toothpicks; you’re not allowed to get Scotch tape. Okay? That’s the challenge. And, as you can see already, mine is starting to lean. Gravity’s always pulling on it. I’m only gonna make mine three toothpicks high, just because I don’t need to make it bigger. That’s gonna be your challenge. Then, I’m gonna simulate an earthquake, and then, I’m gonna see if my structure is still standing. And, there are other things that you can do, actually, to try to make your structure more stable. Questions like, ‛What happens if you added toothpicks across the squares?’ Something like this. Would this help? Would this help? Science is all about asking questions. Test them, and see what happens. That’s two toothpicks high, and now I’m gonna go three toothpicks high. And by the way, if you don’t have marshmallows, you can actually use gumdrops. My whole point of this is, you can build and learn about structure and engineering and earthquakes, using any materials that you have at home. Uh-oh, gravity. Stop. There we go, it does get a little harder as you get higher. You gotta realize that, and you guys are gonna get frustrated. Starts to look like the leaning Tower of Marshmallows. And, I’m just going to put my toothpicks across the top, and then I’m gonna shake the table, and it’s earthquake time. Will my structure still be standing? Will it fall? I

Materials engineering is the field of study which involves design and discovery of new materials, particularly solids. Many of the most pressing scientific problems humans currently face are due to the limits of the materials that are available and how they are used. Thus, breakthroughs in materials science are likely to affect the future of technology significantly. Material Engineers are deeply involved in Understanding the relationships between properties, structure, processing and performance etc which is applied in various fields of work including civil, chemical, construction, nuclear, aeronautical, agricultural, mechanical, biomedical or electrical engineering. Nature of Work Materials engineers develop, process, and test materials used to create a range of products, from computer chips and aircraft wings to golf clubs and biomedical devices. They study the properties and structures of metals, ceramics, plastics, composites, nanomaterials and other substances in order to create new materials that meet certain mechanical, electrical, and chemical requirements. They also help select materials for specific products and develop new ways to use existing materials. The duties of a Materials Engineer include: • Plan and evaluate new projects, consulting with other engineers and managers as necessary • Prepare proposals and budgets, analyze labor costs, write reports, and perform other managerial tasks • Supervise the work of technologists, technicians, and other engineers and scientists • Design and direct the testing of processing procedures • Monitor how materials perform and evaluate how they deteriorate • Determine causes of product failure and develop ways of overcoming such failure • Evaluate technical specifications and economic factors relating to the design objectives of processes or products • Evaluate the impact of materials processing on the environment Materials engineers may specialize in understanding specific types of materials. The following are examples of types of materials engineers: Ceramic engineers develop ceramic materials and the processes for making them into useful products, from high-temperature rocket nozzles to glass for LCD flat-panel displays. Composites engineers develop materials with special, engineered properties for applications in aircraft, automobiles, and related products. Metallurgical engineers specialize in metals, such as steel and aluminum, usually in alloyed form with additions of other elements to provide specific properties. Plastics engineers develop and test new plastics, known as polymers, for new applications. Semiconductor processing engineers apply materials science and engineering principles to develop new microelectronic materials for computing, sensing, and related applications. Now let’s go to, Eligibility and Professional Courses • 10+2 Science with Physics, Chemistry, Mathematics is mandatory with at least 60% marks. • Entrance examinations are conducted for admission to B.E./B.Tech programs in marine engineering.

Check out the official app http://apple.co/1ThDIrx Watch more How to Do Small Science Projects for Children videos: http://www.howcast.com/videos/510860-How-to-Demonstrate-Insulation-Principles-Science-Projects Hey, guys. Has this ever happened to you? You turn on the shower. You’re getting ready to take a shower. You take your clothes off, and you step foot into the shower. The water is freezing, and you scream, right? Well, think about that. The cold water made you literally scream, jump. You jumped out, but why? Well, I want to show you something really cool. Because some animals, think about it, live in ice cold water. How are they able to do that? Well, I’m going to show you how. And all you need are a few materials that I guarantee you have somewhere in your home. All I need is water. And, we’re going to pretend to make really icy cold arctic water. I’m going to load this up with ice. Okay? And just for fun, I always like to do this. When you think of hot, what comes to mind? Red. When you think of cold, what comes to mind? Blue. So check this out. I’m going to add a couple drops of blue food coloring. Just so that it makes you guys really start to think about things that are cold. Now, I’m going to take my hand, and I’m going to put it in the ice cold water. I’m going to see how long it’ll take me to feel the iciness of this water. Eventually it’s going to hurt to the point that I have to pull my hand out. Ready? Set. Go. It’s in. Right now you see, I can take it. I’m a man. Actually, wait. It’s starting to hurt, and it’s really starting to hurt. You see, the ice, the cold from the water is able to penetrate right now through my skin. It’s literally sucking out all the heat from my hand, and right now it’s hurting really bad. I can’t take it anymore. It hurts. But, I’m about to do something that’s going to take my hand, go in the water, and I will be able to leave it in the water all day and not even feel the coldness of the water. Check this out. All I need is a Ziploc bag, and all I need is fat. Yeah, I said fat. Okay? This is called shortening. They use this in cooking. Now I want you to think about a polar bear. Polar bears live their lives in ice cold water. You know why they don’t feel it? Their entire body is wrapped in blubber. The cold from the water literally cannot get through the fat. So the inside of their bodies are warm. The heat stays in, and the cold stays out because of the fat. If you don’t believe me, try this experiment. Spoon, bag, fat. I’m going to become a polar bear. I’m going to grab shortening, blubber, fat. One. Make sure you leave it all the way at the bottom of your Ziploc bag. And I’m going to take, two. Don’t touch it. Grab it from the outside of the bag, so you don’t get any of the fat. It’s really, really sticky. It’s really, really greasy. It’s fat. And I’m going to take three. And, there’s a problem now. Some of you are thinking “Wait a second. Carmelo just said, ‘You’re not supposed to touch it.’ Well, then how am I going to put my hand in there and pretend to be a polar bear?” Well, I’m going to show you a fun little secret. Four teaspoons. That’s a lot of fat. Now check this out. I’m going to make polar bear hand. Get a second Ziploc bag. I’m going to take this, and I’m going to stick this now into the bag of the fat. So it was a Ziploc bag with fat, and my hand in another bag. Now my hand is wrapped around in blubber. Just like a polar bear. This water right now is freezing, and check this out. Put this one in. This hand has fat, blubber, protecting me, keeping the heat in and keeping the cold out. This hand has no blubber, and right now, I’m feeling tons of coldness coming through my finger. It’s just sucking out the heat from my hand, and I feel nothing in my polar bear hand. Okay, it’s starting to hurt. On this one, I’m still like la-de-da-de. I feel nothing. I could swim in this all day. Nothing at all. If you want to check this out, and you want to become a polar bear, get some vegetable shortening, some Ziploc bags, some ice, some water, and go become a polar bear. Have fun.

Machine learning in materials science
A lecture given by Harry Bhadeshia at the University of Birmingham, Department of Materials Science and Metallurgy. Long before machine learning and artificial intelligence became throwaway terms and on occasions seen as threats to our very existence, there were useful attempts to take advantage of what are essentially mathematical methods to deal with complex problems in science. In the context of materials science, the first paper seems to have been published in 1991 [1]. Professor Harry Bhadeshia's own interest was stimulated in 1992, when he did not understand a presentation made at a conference, and followed this up on returning to Cambridge, where he discovered David MacKay (a leader in information theory), then in the Physics Department. They started working together and published the first paper in 1995 [2]. The method turned out to be so powerful that they published 14 papers together in unfunded research over a period of 24 years. In his lecture, Professor Sir Harry Bhadeshia will deal explicitly with the following: (a) A simple and transparent explanation of the method. (b) Question whether there is any intelligence involved. (c) Show how the technique has led to remarkable PREDICTIONS that have been subsequently been verified experimentally. (d) Describe the best way of disseminating the outcomes. [1] Ghaboussi, J., J.

Harry Bhadeshia is the Tata Steel Professor of Metallurgy at the University of Cambridge, with primary interest in the science that leads to novel alloys of iron.

Introduction to Nanomaterials | Lecture | Part-1|
Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 and 1000 nanometres (10−9 meter) but is usually 1—100 nm (the usual definition of nanoscale. Nanomaterials research takes a materials science-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, or mechanical properties. Nanomaterials are slowly becoming commercialized and beginning to emerge as commodities.

PyParis 2017 - Machine Learning in computational materials science by Igor Mosyagin
An overview of the current trends in modern computational materials science and the cross-pollination with DataScience community. I’m going to present a few case studies and give a brief introduction of my own experience with using python in academic community.
Lunes 21 de Marzo de 2012 E. ROB WALLACH DEPARTMENT OF MATERIALS SCIENCE AND METALLURGY UNIVERSITY OF CAMBRIDGE, UK Why are so many of the materials around us interesting, how have they have evolved, what does the future might hold? The radically different responses of the wide range of materials used in very different situations enable us to exploit and benefit in everyday life from their distinctive characteristics. Materials Science has a key role in this area and, as both a matter of responsibility as well as these being topics of interest (and concern?) to the next generation, we need to raise awareness of the subject itself. The seminar will address three ways to raise awareness of Materials Science. The first way is through SeeK (Science & engineering experiments for Kids) which aims to promote the excitement and fun of science and engineering to children (aged 9-11) in primary schools in Cambridge and surrounding villages. Workshops are held in the schools and introduce simple scientific concepts and principles using hands-on experiments. Critical to the success is the input from University of Cambridge students as this allows the children to work in small groups with people who have a strong scientific background and who also can be rôle models. The second way is by short residential courses for prospective students, current science teachers and also alumni of the University. The message is that the knowledge of and also the understanding of materials behaviour allow us to live more efficiently by optimising natural resources more effectively and also by enabling innovation and change. Courses include lectures, laboratory sessions based on experiments carried out by undergraduates, a design and build project, visits to neighbouring museums. All courses also give insights into the research of the University as well as of Cambridge student life. An extension of this approach is through the University's International Science Summer School. The third way is through undergraduate education. Students in Cambridge spend their first year studying three (from a total of seven) experimental sciences and this pattern is repeated with slightly greater specialisation in their second year. Only in their third and fourth years do they concentrate on just one subject. Materials Science is one of the seven first-year courses and, for many students, it is a relatively new subject. Many students, who originally intended to specialise in other physical sciences at university, such as physics and chemistry, choose Materials Science in later years if the subject is presented as exciting and relevant, and this is our challenge. The talk will share the background to Materials Science education in the University of Cambridge, and also the rationale of a course developed to address energy considerations and potential solutions for improved energy provision. Further understanding and development of materials are essential given the growing challenges of the twentyfirst century namely, social, economic and environmental. Science and technology must provide some solutions and Materials Science has a pivotal role. Los Seminarios Internacionales de Fronteras de la Ciencia de Materiales son organizados por el Departamento de Ciencia de Materiales de la Universidad Politécnica de Madrid, y tienen periodicidad semanal. Su objetivo es servir de punto de encuentro, interacción y difusión de problemáticas actuales y destacadas dentro del área de la Ciencia e Ingeniería de Materiales; con una visión amplia que va desde los materiales biológicos a los materiales funcionales, pasando por aplicaciones puramente tecnológicas. En ellos se cuenta con la participación desinteresada de relevantes investigadores y tecnólogos de Universidades, Empresas y Centros de Investigación del ámbito nacional e internacional.
