It’s common sense – in order to brush your teeth, you need water, a toothbrush, and toothpaste. Well, a company from Japan wants to change all that: they’ve developed a nanotechnology toothbrush that basically eliminates the need for toothpaste.
A team at Caltech has devised a new film coating that facilitates catalysis and electron transfer in a solar powered system that splits water into hydrogen and oxygen, which can be used as fuels. Such a system is also called an artificial leaf or solar-fuel generator because in many ways it mimics the process which plants use to convert sunlight and CO2 into oxygen and fuel (sugars, carbohydrates). The researchers make note, however, that they’re still a long way from making it commercial viable, but these sort of updates are inspiring.
A new generation of water-repellent products could be just ahead after researchers at University of Rochester demonstrated an amazing laser technique that etches tiny micro and nano grooves into a metal surface making it super-hydrophobic.
A novel type of nanowire crystals was demonstrated by researchers at the University of Copenhagen that can fuse together both semiconductor and metallic materials with atomic precision at their interface. This way, nanowires and their electrical contacts have been fused in one hybrid material which might lay the foundation for the next generation of semiconductor electronics. A perfect fit In the
Researchers at Northwestern University and the University of Illinois at Urbana-Champaign recently demonstrated a new technique for building complex and very fine 3D micro and nano structures out of 2-D shapes. The whole process is very similar to how a children’s pop-up book works, starting as a flat 2D surface only to expand into a 3D shape when prompted. The authors note that the pop-up method has various advantages over 3D printing, including use of multiple materials during the fabrication process and integration with electronics.
At just 10 µm across, this little guy is only 1/5th the width of a human hair. The snowman was made from two tin beads used to calibrate electron microscope astigmatism. The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide (or 0.001 mm), is ion beam deposited platinum. Image and
A breakthrough in optical communications has been reported by Stanford engineers who used a complex algorithm to design a prism-like device that splits light into different colours (frequencies) and at right angles. This is the absolute first step towards building a circuit, and ultimately a computer, that uses light instead of wires to relay signals. This way, much more compact and
An Israeli company has developed a battery that can charge a smartphone in just 30 seconds; to make things even more interesting, the technology could be scaled and power up electric cars in a matter of minutes. Demonstrated at the 2014 Microsoft Think Next Conference in Tel Aviv earlier this year, StoreDot‘s prototype battery fully charged a Samsung Galaxy S4 in just
How many angels can dance on the head of a pin? This nonsensical question actually has meaning in the world of Jonty Hurwitz, an anamorphic artist. For his latest project, Hurwitz teamed with the Karlsruhe Institute of Technology and the Weitzmann Institute of Science to 3D print sculptures that recreate the smallest human forms ever. These figurines are only 20x80x100 microns, or
On Tuesday, Google’s head of life sciences inside the company’s Google X research lab reported a new exciting project that involves using nanoparticles that magnetically attach to key molecules and cells in the bloodstream to detect diseases, including cancer. The particles – ingested under the form of a pill – would later be gathered, scanned and monitored through a non-invasive wearable
