A simple way to carve patterns onto nanodiamonds without damaging them could lead to a new generation of photonic devices, say materials scientists.
Physicists have long known that entangled photons can make more precise measurements than independent ones. Now Japanese physicists have built a microscope that proves it.
In August, the blog revealed that chains of double or triple-bonded carbon atoms, known as carbyne, should be stronger and stiffer than any known material.
By adding laser dyes to organic fibers, researchers have demonstrated a technique that should lead to textiles that lase at all visible frequencies.
The were first predicted in 2005 and first synthesized in the lab in 2008. Now physicists have discovered a naturally occurring topological insulator that can be mined from the earth's crust.
In the same way that metamaterials steer light around objects to hide them, they might also steer electrons through crystal lattices with zero resistance, say physicists.
A simple way to print circuits on a wide range of flexible substrates using an inkjet printer has eluded materials scientists. Until now.
"Capillary charges", which act like magnetic poles on the surface of liquids, can pull millimetre-sized building blocks together, a technique that promises a new era of mesoscopic-scale manufacturing.
Cheap, simple water filters made of plant xylem could dramatically reduce the incidence of water-borne diseases in places without access to clean drinking water, say engineers.
If you thought a blob of oil is a good-for-nothing, useless, errr, blob, here's a video that will make you think again.
