Materials scientists have decided to define, rather than measure, Avogadro's constant, triggering a lengthy debate over what number to choose. Now one physicist thinks he has the answer.
Particles of dark matter should trigger nanoexplosions in certain materials, an idea that could lead to an entirely new generation of detectors, say physicists.
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.
