New nanomaterial can extract hydrogen fuel from seawater

It’s possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF researcher Yang Yang has come up with a new hybrid nanomaterial that harnesses solar energy and uses it to generate hydrogen from seawater more cheaply and efficiently than … Continue reading “New nanomaterial can extract hydrogen fuel from seawater”

Scientists discover genes are controlled by ‘nano footballs’

Research at the University of York has revealed that genes are controlled by ‘nano footballs’ – structures that look like footballs but 10 million times smaller than the average ball. By placing tiny glowing probes on transcription factors – special chemicals inside cells which control whether a gene is switched ‘on’ or ‘off’ – researchers … Continue reading “Scientists discover genes are controlled by ‘nano footballs’”

Nanoscale printing breakthrough creates two colours per pixel

Scientists have developed a new form of high-resolution ‘printing’ which could have wide-ranging applications in data storage, anti-counterfeiting measures, and digital imaging. New research from the University of Glasgow, published today (Wednesday 20 September) in the journal Advanced Functional Materials, outlines how engineers have developed nano-scale plasmonic colour filters that display different colours depending on the … Continue reading “Nanoscale printing breakthrough creates two colours per pixel”

HRL Engineers 3-D print high-strength aluminum, solve ages-old welding problem using nanoparticles

HRL Laboratories has made a breakthrough in metallurgy with the announcement that researchers at the famous facility have developed a technique for successfully 3D printing high-strength aluminum alloys—including types Al7075 and Al6061—that opens the door to additive manufacturing of engineering-relevant alloys. These alloys are very desirable for aircraft and automobile parts and have been among … Continue reading “HRL Engineers 3-D print high-strength aluminum, solve ages-old welding problem using nanoparticles”

FFNG to draw electricity from the bloodstream

Men build dams and huge turbines to turn the energy of waterfalls and tides into electricity. To produce hydropower on a much smaller scale, Chinese scientists have now developed a lightweight power generator based on carbon nanotube fibers suitable to convert even the energy of flowing blood in blood vessels into electricity. For thousands of … Continue reading “FFNG to draw electricity from the bloodstream”
