Artificial photosynthesis system converts water into hydrogen
The energy available in sunlight is a resource we’ve only begun to really get a handle on. Current photovoltaic-cell technology, typically a semiconductor-based system, is expensive, not very efficient, and only does instant conversions from sunlight to electricity. But an artificial photosynthesis system or a photo-electrochemical cell that mimics what… »

Flexible, stretchable, nearly indestructible CNT loudspeakers
A thin film based on carbon nanotubes (CNT) could replace conventional magnetic loudspeakers. By applying an audio frequency current through the CNT, the loudspeaker can generate sound with wide frequency range, high sound pressure levels (SPL), and low total harmonic distortion (THD). The uniqueness of this advancement is that the… »

Capsules for self-healing electronic circuits
Researchers, from the University of Illinois at Urbana-Champaign, are also working on capsule additives designed to heal failures in lithium-ion battery electrodes, to prevent the short-circuiting that can sometimes cause a fire. Capsules filled with conductive nanotubes that rip open under mechanical stress could be placed on circuit boards… »

Bacteriophage which produce nanoscale electronics
For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery. Angela Belcher, the MIT materials scientist who led the research team said “The new virus-produced batteries have the same energy capacity and power performance… »

World’s smallest light bulb created at UCLA
It’s actually so small that even the researchers had to publish an artist rendering of the light bulb instead of a real photo. Besides other usages it will help in an effort to explore the boundary between thermodynamics and quantum mechanics – two fundamental yet seemingly incompatible theories of physics…. »

Two methods to produce graphene nanoribbons
You remember we wrote about carbon nanotubes (CNTs) in one of our previous articles? Two groups of researchers have found ways to unfold CNTs in order to make nanoribbons of graphene. The experts claim that the development could point the way towards a new generation of electronics, including computer chips… »

Nanotechnologies – Carbon nanotubes
The discovery of nanotubes remains a debatable issue, especially because several scientists involved in the research could be likely candidates for the Nobel Prize. A large percentage of academic and popular literature attributes the discovery of hollow, nanometer-size tubes composed of graphitic carbon to Sumio Iijima of NEC in 1991…. »
