Artificial membranes on silicon

Artificial membranes mimicking those found in living organisms have many potential applications ranging from detecting bacterial contaminants in food to toxic pollution in the environment to dangerous diseases in people. Now a group of scientists has developed a way to create these delicate, ultra-thin constructs through a 'dry' process, by evaporating two commercial, off-the-shelf chemicals onto silicon surfaces.

Buckyballs and diamondoids join forces in nanoelectronics

Researchers have married two unconventional forms of carbon to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

First-ever look inside a working lithium-ion battery (w/video)

In an unprecedented view inside a working lithium-ion battery, researchers used a neutron beam to 'see' lithium flow as the battery charged and discharged. The study could one day help explain why rechargeable batteries lose capacity over time, and sometimes even catch fire.

A low-energy optical circuit for a new era of technology

Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building-block for photonic 'transistors' that requires record-low energy to operate. The device is a big step forward in the development and implementation of optical circuits.

Two-dimensional phosphorus a promising semiconductor

Researchers analyzed the properties of elemental bonds between semiconducting phosphorus atoms in 2-D sheets. Two-dimensional phosphorus is not theoretical; it was recently created through exfoliation from black phosphorus.
