A brighter design emerges for low-cost, 'greener' LED light bulbs

The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given LED lighting a sales boost. However, that trend could be short-lived as key materials ...

Studies would lead to lighter, cheaper magnets

(Phys.org) —Sometimes you have to apply a little pressure to get magnetic materials to reveal their secrets. By placing a permanent magnet under high pressures, Lawrence Livermore researchers are exploring how atomic structure ...

For perfect nano-crystals, just add water

A simplified technique to fabricate nano-crystals of cerium dioxide (CeO2), which have wide-ranging technological and industrial applications, has been "unexpectedly" demonstrated by a UNSW chemist.

New family of tiny crystals glow bright in LED lights

(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

New 'ATM' takes old phones and gives back green

When new cell phones or tablets enter the marketplace, yesterday's hot technology can quickly become obsolete - for some consumers. For others, the device still has value as an affordable alternative, or even as spare parts.

Life's first taste of phosphorus

Despite its impressive biological resume, phosphorus is relatively inaccessible as elements go. To understand how phosphorus obtained its prominent role, scientists are modeling the early geochemical environment on Earth ...

Clean energy could lead to scarce materials

As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.
