Net-zero energy test house exceeds goal; ends year with energy to spare

Posted: 01 Jul 2014 03:38 PM PDT

The NIST net-zero energy test house in suburban Washington, D.C., not only absorbed winter's best shot, it came out on top, reaching its one-year anniversary on July 1 with enough surplus energy to power an electric car for about 1,440 miles.

Solar panels light the way from carbon dioxide to fuel

Posted: 01 Jul 2014 02:01 PM PDT

Researchers have devised an efficient method for harnessing sunlight to convert carbon dioxide into a potential alternative fuel known as formic acid. The transformation from carbon dioxide and water to formic acid was powered by a commercial solar panel.

Bolstering batteries with nanotubes

New metamaterial gives light a one-way ticket

Posted: 01 Jul 2014 03:38 PM PDT

Researchers have built a silver, glass and chromium nanostructure that can all but stop visible light cold in one direction while giving it a pass in the other. The device could someday play a role in optical information processing and in novel biosensing schemes.

New bridge design improves earthquake resistance, reduces damage and speeds construction

Posted: 01 Jul 2014 11:29 AM PDT

Researchers have developed a new design for the framework of columns and beams that support bridges, called 'bents,' to improve performance for better resistance to earthquakes, less damage and faster on-site construction.

Muscle-powered bio-bots walk on command

Posted: 01 Jul 2014 11:28 AM PDT

A new generation of miniature biological robots is flexing its muscle. Engineers have demonstrated a class of walking 'bio-bots' powered by muscle cells and controlled with electrical pulses, giving researchers unprecedented command over their function.

Weave a cell phone into your shirt? Engineers envision an electronic switch just three atoms thick

Posted: 01 Jul 2014 06:20 AM PDT

Researchers believe they've discovered a crystal that can form a monolayer three atoms thick. Computer simulations show that this crystal, molybdenum ditelluride, can act like a switch: its crystal lattice can be mechanically pulled and pushed, back and forth, between two different atomic structures -- one that conducts electricity well, the other that does not. The team hopes experimental scientists will make this semiconductor crystal and use it to fashion flexible electronics.

Growth of metallic silver on surface of silver tungstate crystals as a result of electrosynthesis

Posted: 30 Jun 2014 06:45 AM PDT

The growth of metallic silver on the surface of silver tungstate crystals (Ag2WO4) using high resolution and hign transmission scanning microscopes has been reported by researchers. This phenomenon has not been observed before, and results from the interaction of the electrons generated by the microscope with the silver ions, that are reduced to metallic silver.
