Laser-etching pattern turns any metal into a super-hydrophobic surface

Super hydrophobic surface

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

‘Pop-up’ method makes 3-D complex nano structures from 2-D, similar to a children’s book

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.

The World’s Smallest Snowman

snowman

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

This new battery can fully charge your smartphone in 30 seconds

phone charger

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

Google plans Magnetic Nanoparticle pill that detects diseases like Cancer

nanoparticles

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

A team at Harvard’s Wyss Institute for Biologically Inspired Engineering demonstrated the latest advances in programmable DNA self-assembly by crystallizing 32 structures with precisely prescribed depths and complex 3D features. The DNA crystals could potentially be used as the basis of a programmable material platform that would allow scientists to build extremely precise and complex structures rivaling the complexity of

Underwater glue inspired by shellfish might help repair ships

strongest underwater glue

Taking inspiration from nature, scientists at MIT have engineered a new sort of glue that acts like a powerful adhesive even in underwater conditions and can cling on to virtually any surface, be it metal or organic. The glue might prove to be useful to repair ships or seal wounds and surgical incisions. The strongest underwater glue to date Shellfish
