#Quantum states in a nano-object manipulated using a mechanical system Scientists at The swiss Nanoscience Institute at the University of Basel have used resonators made from single-crystalline diamonds to develop a novel device in
the research team led by Georg H. Endress Professor Patrick Maletinsky described how resonators made from single-crystalline diamonds with individually embedded electrons are suited highly to addressing the spin of these electrons.
These diamond resonators were modified in multiple instances so that a carbon atom from the diamond lattice was replaced with a nitrogen atom in their crystal lattices with a missing atom directly adjacent.
In these"nitrogen-vacancy centers,"individual electrons are trapped. Their"spin"or intrinsic angular momentum is examined in this research.

It is conceivable that this diamond resonator could be applied to sensors--potentially in a highly sensitive way

During testing, the team scratched the material with stainless steel tweezers, screwdrivers, diamond-tipped scribers and pummeled it with hundreds of thousands of hard, heavy beads.
It is second only to diamond in hardness, although incorrect processing can leave defects that make it brittle.

#Scientists create riction-freematerial US Department of energy Scientists at the Argonne National Laboratory have found a way to use diamonds
Led by nanoscientist Ani Sumant of Argonne Center for Nanoscale Materials (CNM) and Argonne Distinguished Fellow Ali Erdemir of Argonne Energy systems Division, the Argonne team combined diamond
and a diamond-like carbon material to create superlubricity, a highly-desirable property in which friction drops to near zero.
as the graphene patches and diamond particles rub up against a large diamond-like carbon surface, the graphene rolls itself around the diamond particle, creating something that looks like a ball bearing on the nanoscopic level. he interaction between the graphene
and the diamond-like carbon is essential for creating the uperlubricityeffect, he said in a statement. he two materials depend on each other.
By creating the graphene-encapsulated diamond ball bearings, or scrolls, the team found a way to translate the nanoscale superlubricity into a macroscale phenomenon.
Because the scrolls change their orientation during the sliding process, enough diamond particles and graphene patches prevent the two surfaces from becoming locked in state.
The team used large-scale atomistic computations on the Mira supercomputer at the Argonne Leadership Computing Facility to prove that the effect could be seen not merely at the nanoscale

Conventional methods for creating materials with high pressure use tiny diamond anvils to poke or squeeze materials.
However, the ultra-short laser micro-explosion creates pressures many times higher than the strength of diamond crystal can produce.
