Penn Researchers Establish Universal Signature Fundamental Glassy Materials Fail
2017/12/18
Dropping a smartphone on its glass screen, which is made of atoms jammed together with no discernible order, could result in it shattering. Unlike metals and other crystalline materials, glass and man...
Penn Researchers Make Thinnest Plates That Can Be Picked Up by Hand
Penn Researchers Thinnest Plates Be Picked Up by Hand
2015/12/14
Scientists and engineers are engaged in a global race to make new materials that are as thin, light and strong as possible. These properties can be achieved by designing materials at the atomic level,...
Penn Researchers Discover New Chiral Property of Silicon,With Photonic Applications
Penn Researchers New Chiral Property Silicon Photonic Applications
2015/8/4
y encoding information in photons via their spin, “photonic” computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin...
Penn Researchers Develop Liquid-crystal-based Compound Lenses That Work Like Insect Eyes
Penn Researchers Liquid-crystal-based Compound Lenses Work Like Insect Eyes
2015/5/25
The compound eyes found in insects and some sea creatures are marvels of evolution. There, thousands of lenses work together to provide sophisticated information without the need for a sophisticated b...
Penn Researchers Develop New Technique for Making Graphene Competitor, Molybdenum Disulphide
Penn Researchers Making Graphene Competitor Molybdenum Disulphide
2015/3/4
Graphene, a single-atom-thick lattice of carbon atoms, is often touted as a replacement for silicon in electronic devices due to its extremely high conductivity and unbeatable thinness. But graphene i...
Penn Researchers Show Commonalities in How Different Glassy Materials Fail
Different Glassy Materials Fail
2014/12/30
Glass is mysterious. It is a broad class of materials that extends well beyond the everyday window pane, but one thing that these disparate glasses seem to have in common is that they have nothing in ...

design for failure model materia
2014/3/18
When deciding what materials to use in building something, determining how those materials respond to stress and strain is often the first task. A material’s macroscopic, or bulk, properties in this a...
