Next-generation antireflection coatings could improve solar photovoltaic cell efficiency Posted: 26 Oct 2012 12:34 PM PDT Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface.

Strengthening fragile forests of carbon nanotubes for new MEMS applications Posted: 26 Oct 2012 11:32 AM PDT By using a variety of materials not commonly associated with MEMS technology, researchers have created stronger microstructures that can form precise, tall and narrow 3-D shapes – characteristics that were never before possible in MEMS.

Near-atomically flat silicon could help pave the way to new chemical sensors Posted: 26 Oct 2012 11:32 AM PDT Scientists have succeeded in creating near-atomically flat silicon, of the orientation used by the electronics industry, in a room temperature reaction. The flat silicon might one day serve as the base for new biological and chemical sensors.

Nanotechnology helps scientists keep silver shiny Posted: 26 Oct 2012 11:32 AM PDT There are thousands of silver artifacts in museum collections around the world, and keeping them shiny is a constant challenge. A team of researchers is investigating less labor-intensive ways to protect silver artifacts from tarnishing.

New materials may help prevent infections by blocking initial bacterial attachment Posted: 26 Oct 2012 11:32 AM PDT Recently a team of British researchers has discovered a new class of materials that resists bacterial attachment.

High-efficiency quantum dot solar cells developed Posted: 26 Oct 2012 11:32 AM PDT Scientists have demonstrated the first solar cell with external quantum efficiency (EQE) exceeding 100 percent for photons with energies in the solar range.

Scientists build 'nanobowls' to protect catalysts needed for better biofuel production Posted: 26 Oct 2012 11:32 AM PDT Researchers are using a layering technique developed for microchip manufacturing to build nanoscale "bowls" that protect miniature metal catalysts from the harsh conditions of biofuel refining.

Glass: Characterizing with precision and efficiency Posted: 26 Oct 2012 09:48 AM PDT Glass can possess a quite diverse array of characteristics, depending on what ingredients one uses to modify it. A new process now makes the analysis of glass characteristics easier: Up to five-times faster than predecessor methods, this process only requires 20 percent of the material.

Technology helping to crack oldest undeciphered writing system Posted: 26 Oct 2012 08:12 AM PDT New technology has allowed researchers to come closer than ever to cracking the world's oldest undeciphered writing system. Researchers in the UK have developed a Reflectance Transformation Imaging (RTI) System for Ancient Documentary Artefacts to capture images of some of the world's most important historical documents. Recently this system was used on objects held in the vaults of the Louvre Museum in Paris.
