Smallest possible diamonds form ultra-thin nanothreads

Posted: 21 Sep 2014 11:51 AM PDT

For the first time, scientists have discovered how to produce ultra-thin 'diamond nanothreads' that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The threads have a structure that has never been seen before.

From light into matter, nothing seems to stop quantum teleportation

Posted: 21 Sep 2014 11:50 AM PDT

Physicists have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment constitutes a first, and simply pulverizes the previous record of 6 kilometers achieved ten years ago by the same team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it is not the composition of a particle which is important, but rather its state, since this can exist and persist outside such extreme differences as those which distinguish light from matter.

A nanosized hydrogen generator

Posted: 19 Sep 2014 01:54 PM PDT

Researchers have created a small scale "hydrogen generator" that uses light and a two-dimensional graphene platform to boost production of the hard-to-make element. The research also unveiled a previously unknown property of graphene. The two-dimensional chain of carbon atoms not only gives and receives electrons, but can also transfer them into another substance.
