Freshmen-level chemistry solves the solubility mystery of graphene oxide films

Common contaminant found responsible for the material's stability in water


A Northwestern University-led team recently found the answer to a mysterious question that has puzzled the materials science community for years - and it came in the form of some surprisingly basic chemistry.Like many scientists, Jiaxing Huang did not understand why graphene oxide (GO) films were ...

Penn researchers show commonalities in how different glassy materials fail


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 common when it comes to their internal structures, especially in contrast with highly ordered and ...


'Topological insulators' promising for spintronics, quantum computers


Researches have uncovered "smoking-gun" evidence to confirm the workings of an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more powerful than today's technologies. The materials are called "topological insulators." Unlike ordinary ...


Bending - but not breaking - in search of new materials

Drexel engineers improve strength and flexibility of atom-thick films


Making a paper airplane in school used to mean trouble. Today it signals a promising discovery in materials science research that could help next-generation technology - like wearable energy storage devices - get off the ground. Researchers at Drexel University and Dalian University of Technology ...

A billion holes can make a battery


Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds ...

Good vibrations give electrons excitations that rock an insulator to go metallic


For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize-winning physicist Nevill Mott in thinking direct interactions between electrons were the key. ...

Fundamental chemistry findings could help extend Moore's Law


Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process ...


Strongly interacting electrons in wacky oxide synchronize to work like the brain


Current computing is based on binary logic - zeroes and ones - also called Boolean computing, but a new type of computing architecture stores information in the frequencies and phases of periodic signals and could work more like the human brain using a fraction of the energy necessary for today's ...


David J. Srolovitz Awarded 2013 Materials Theory Award

University of Pennsylvania professor receives award for exceptional advances in theoretical materials science


The Materials Research Society (MRS) has named David J. Srolovitz, University of Pennsylvania, to receive its Materials Theory Award for his “decisive and highly influential contributions to the theory and simulation of microstructure, morphological evolution, mechanical behavior, and the ...

Carbon's new champion

Rice U. theorists calculate atom-thick carbyne chains may be strongest material ever


Carbyne will be the strongest of a new class of microscopic materials if and when anyone can make it in bulk. If they do, they'll find carbyne nanorods or nanoropes have a host of remarkable and useful properties, as described in a new paper by Rice University theoretical physicist Boris Yakobson ...
