Super high-res 3D laser printer: high-speed 3D printing of tiny objects
Posted by admin in Hi-tech, Science on 13. Mar, 2012 | 0 Comments
Are 3D printers not amazing enough already? Apparently some scientists at the Vienna University of Technology (TU Vienna) didn’t think so, as they have now built one that can create intricate objects as small as a grain of sand. While the ability to 3D-print such tiny items is actually not unique to the TU Vienna [...]
MIT’s Nano-Bio-Bandage Can Stop Your Bleeding Almost Immediately

Bleeding out on the battlefield–far from the trauma wards and triage units that might save their lives–is a scenario that soldiers simply have to live with (and try like hell to avoid). But thanks to ananoscale breakthrough at MIT, the chances of it happening could be significantly reduced. Researchers there have created a nanoscale coating [...]
New cloaking device:invisibility cloak

You have no doubt seen mirages on the distant surfaces of hot highways before, looking like pools of water shimmering on the asphalt. Such illusions are caused by hot air above the road, which refracts light waves coming down into it from the cooler air above – in other words, the supposed "water" is actually [...]
Lightweight cable made of braided nanotubes could replace copper wires

Cables made out of nanowires could be just as efficient as the copper cables we’ve been using for more than a century, but at a fraction of the weight, according to a new paper. Braiding billions of carbon nanotubes into a nanowire cable can efficiently replace copper in a light bulb circuit. Traditional cables are [...]
Researchers use DNA to coax quantum dots Into self-assembling into a light antenna

Or, how to build artificial molecules Quantum Dots Tiny semiconducting nanocrystals–quantum dots–can be engineered to absorb and emit a range of light wavelengths. Taking cues from DNA research, photosynthesis, and nanotechnologies, a team at the University of Toronto has engineered a new kind of “artificial molecule” that can be assembled into wholly new classes of [...]
