University lab demonstrates 3-D printing in glass

A team of engineers and artists working at the University of Washington's Solheim Rapid Manufacturing Laboratory has developed a way to create glass objects using a conventional 3-D printer. The technique allows a new material ...

The secret behind crystals that shrink when heated

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have new experimental evidence and a predictive theory that solves a long-standing materials science mystery: why certain crystalline materials ...

Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their ...

New study confirms exotic electric properties of graphene

(PhysOrg.com) -- First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat ...

Materials that shrink when heated

One common reason that people with fillings experience toothache is that their fillings expand at a different rate to the original tooth when, for example, drinking a hot drink. Contrary to intuition, however, not all materials ...

An unlikely route to ferroelectricity

(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain materials. This ...

New Hitachi Li-ion batteries to last ten years

(PhysOrg.com) -- Hitachi has announced they may be able to double the life of rechargeable lithium-ion (Li-ion) batteries through the development of a new cathode material. The material was developed in conjunction with the ...

Researcher uses nanosilica to strengthen concrete (w/ video)

Every day, concrete structures crack and erode prematurely due to Alkali Silica Reactivity (ASR), a chemical reaction that causes fissures in the material as it sets. Jon Belkowitz, a doctoral student at Stevens Institute ...
