Scientists find an equation for materials innovation - 0 views

By reworking a theory first proposed by physicists in the 1920s, the researchers discovered a new way to predict important characteristics of a new material before it's been created. The new formula allows computers to model the properties of a material up to 100,000 times faster than previously possible and vastly expands the range of properties scientists can study. "The equation scientists were using before was inefficient and consumed huge amounts of computing power, so we were limited to modeling only a few hundred atoms of a perfect material," said Emily Carter, the engineering professor who led the project. "But most materials aren't perfect," said Carter, the Arthur W. Marks '19 Professor of Mechanical and Aerospace Engineering and Applied and Computational Mathematics. "Important properties are actually determined by the flaws, but to understand those you need to look at thousands or tens of thousands of atoms so the defects are included. Using this new equation, we've been able to model up to a million atoms, so we get closer to the real properties of a substance." By offering a panoramic view of how substances behave in the real world, the theory gives scientists a tool for developing materials that can be used for designing new technologies. Car frames made from lighter, strong metal alloys, for instance, might make vehicles more energy efficient, and smaller, faster electronic devices might be produced using nanowires with diameters tens of thousands of times smaller than that of a human hair.

Princeton engineers have made a breakthrough in an 80-year-old quandary in quantum physics, paving the way for the development of new materials that could make electronic devices smaller and cars more energy efficient.
New Rocket Engine Could Reach Mars in 40 Days - Yahoo! News - 0 views

A mission trajectory study estimated that a VASIMR-powered spacecraft could reach the red planet within 40 days if it had a 200 megawatt power source. That's 1,000 times more power than what the current VASIMR prototype will use, although Ad Astra says that VASIMR can scale up to higher power sources. The real problem rests with current limitations in space power sources. Glover estimates that the Mars mission scenario would need a power source that can produce one kilowatt (kW) of power per kilogram (kg) of mass, or else the spacecraft could never reach the speeds required for a quick trip. Existing power sources fall woefully short of that ideal. Solar panels have a mass to power ratio of 20 kg/kW. The Pentagon's DARPA science lab hopes to develop solar panels that can achieve 7 kg/KW, and stretched lens arrays might reach 3 kg/KW, Glover said. That's good enough for VASIMR to transport cargo around low-Earth orbit and to the moon, but not to fly humans to Mars. Ad Astra sees nuclear power as the likeliest power source for a VASIMR-powered Mars mission, but the nuclear reactor that could do the job remains just a concept on paper. The U.S. only ever launched one nuclear reactor into space back in 1965, and it achieved just 50 kg/kW.

Future Mars outposts or colonies may seem more distant than ever with NASA's exploration plans in flux, but the rocket technology that could someday propel a human mission to the red planet in as little as 40 days may already exist. A company founded by former NASA astronaut Franklin Chang-Diaz has been developing a new rocket engine that draws upon electric power and magnetic fields to channel superheated plasma out the back. That stream of plasma generates steady, efficient thrust that uses low amounts of propellant and builds up speed over time. "People have known for a long time, even back in the '50s, that electric propulsion would be needed for serious exploration of Mars," said Tim Glover, director of development at the Ad Astra Rocket Company.

This is NOT Real Life! The Future of Gaming Never Looked so Good « 2016 Futur... - 0 views

This video is a pretty impressive showcase of graphics technology that is possible with the Unreal 4 engine TODAY. I seriously had to do a double take as well on a few of these! My brain was fooled a few times, for sure. It's a showcase of various technical demos and a tribute if you will to the sheer power of the Unreal 4 engine. Some of these were from 2015 or earlier! So imagine, what's going to be possible in 2016 and beyond! And with the advent of VR upon us, this only makes the future of gaming that much more exciting! What's everyone think of these? Is the photorealism of gaming graphics shown here going to be possible in every game over the next few years or is this just going to be for the top tier developers?

Explore & Share at 9th World Congress on Biopolymers & Bioplastics, London, UK (A solution for Current & Future Global Predicament) August 26-27, 2019 London, UK: Since 2016, Biopolymer Congress has been contributing successfully to the global scientific research field. 8th World Congress on Biopolymers & Bioplastics was held during June 28-29, 2018 at Berlin, Germany with the theme "Biopolymer- A Drug to heal the nature". Active participation of Scientists, Engineers, Researchers, Students and Leaders from the fields of Polymer Science, plastics, Green technology, medical, and Biomaterials is highly appreciated and made this event a blast. Thanks to all of our Organizing Committee members, honourable guests, wonderful speakers, conference attendees and Media partners. With the success of Biopolymer Congress 2018 at Berlin, we are feeling proud to announce Biopolymer Congress 2019 conference with the theme "A solution for current & future Global predicament", is going to held in London, UK, during August 26-27, 2019. Importance and Scope: Over the past few years, global economic activities have increased a lot. This tremendous growth has raised serious problems about current important patterns of production and consumption. As the current society has increased its attention in understanding of the environmental aspects and its industrial practices, greater attention has been given to the concept of sustainable economic systems that rely on energy from undepletable source and materials. The use of biologically derived Polymers become as an important component of this global world. The history of Biopolymer is not a long one. Various reasons are associated with the research and development of Biopolymers. Use of Bioplastics will make a tremendous change and will help rid of the conventional plastics, which is a welcome change. Why to attend?: To take preventive steps for Global Predicament, Biopolymer Congress 2019 offers a fantastic opportunity to meet and
