Zinc oxide materials tapped for tiny energy harvesting devices

Posted: 13 Jan 2015 09:09 AM PST

Today, we're surrounded by a variety of electronic devices that are moving increasingly closer to us -- we can attach and wear them, or even implant electronics inside our bodies. Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable and powered by ambient renewable energy.

Novel multiferroic materials, devices integrated with silicon chips developed

Posted: 13 Jan 2015 08:16 AM PST

Two advances in multiferroic materials have been made by scientists, including the ability to integrate them on a silicon chip, which will allow the development of new electronic memory devices. The researchers have already created prototypes of the devices and are in the process of testing them.

Predicting properties of the surface of titanium dioxide crystals

Posted: 13 Jan 2015 08:15 AM PST

A new article investigates the surface of titanium dioxide crystals.

Glass for battery electrodes

Posted: 13 Jan 2015 08:15 AM PST

Today's lithium-ion batteries are good, but not good enough if our future energy system is to rely on electrical power. Chemists and materials scientists have now developed a type of glass that can be used as an electrode material in lithium-ion batteries -- likely making a vast improvement in these batteries' capacity and energy density.

Fast sorting of CD4+ T cells from whole blood using glass microbubbles

Posted: 13 Jan 2015 08:14 AM PST

A new report has demonstrated a new cell sorting technology for isolating CD4 positive T cells which may be used for HIV disease monitoring in resource-limited areas such as the developing countries in Africa.

Novel inorganic material emitting laser light in solution discovered

Posted: 13 Jan 2015 06:05 AM PST

Scientists have discovered a new type of laser material based on an inorganic molecule -- a complex of boron and hydrogen and no carbon atoms -- that emits laser light in solution.

Wonder material silicene still stands just out of reach

Posted: 12 Jan 2015 03:10 PM PST

Silicene is the thinnest form of silicon. It is metallic, has graphene-like mobile carriers and can behave like a semiconductor. The wonder material could lead to even smaller electronics but challenges remain.

New superconducting hybrid crystals

Posted: 12 Jan 2015 10:54 AM PST

A new type of 'nanowire' crystals that fuses semiconducting and metallic materials on the atomic scale could lay the foundation for future semiconducting electronics.
