New technique builds graphene-boron sheets without substrate

August 29, 2012 11:34 am | by Anne Ju | News | Comments

Engineers at Cornell University have invented a way to pattern single atom films of graphene and boron nitride, an insulator, without the use of a silicon substrate. The technique, called patterned regrowth, is reliant on conventional silicon photolithography technology and could lead to substrate-free circuits that would be atomically thin yet retain high tensile strength and superior electrical performance.

Single-electron diode could control heat flow in future electronics

August 29, 2012 9:20 am | News | Comments

In attempt to achieve better control of heat flows in electronic devices, a researcher in Finland has invented two new mesoscopic devices based on the behavior of single electrons in a constructed system. The inventions, which include a diode, or rectifier, specifically address the heat carried by an electron and help produce a strongly asymmetric heat flow. The next step will be to manage larger currents.

Self-assembling microscopic “reagents” pioneer pourable electronics

August 29, 2012 9:14 am | News | Comments

A research university in Germany has recently won first place a competition between “unconventional” computing solutions with something called a MICREAgent lablet. The unusual invention is a self-assembling electronic device almost as small as a biological cell. At its heart is a 3D microchip, or lablet, that can produce desired chemicals or coatings when given electronic instructions.

A new use for atomically engineered gold

August 29, 2012 9:09 am | News | Comments

A University of Central Florida assistant professor has developed a new material using nanotechnology, which could help keep pilots and sensitive equipment safe from destructive lasers. Working with gold nanoparticles and studying their properties when they are shrunk into a small size regime called nanoclusters, the team found that nanoclusters developed by adding atoms in a sequential manner could provide interesting optical properties.


Liquid crystal film on gold produces ultra-compact color filter
