Many of the biological materials that researchers are most interested in studying, including those associated with major diseases, don’t lend themselves to the conventional methods that researchers ty...
Scientists mimic the brain’s functions with junctions between vertically aligned graphene and diamond
graphene-diamond junction imitation of human brain function memory
2021/8/10
The human brain holds the secret to our unique personalities. But did you know that it can also form the basis of highly efficient computing devices? Researchers recently showed how to do this, throug...

Working under pressure:Diamond micro-anvils made by UAB will produce immense pressures to make new materials
Diamond micro-anvils made UAB produce immense pressures make new materials
2016/11/4
University of Alabama at Birmingham researchers will use pressures greater than those found at the center of the Earth to potentially create as yet unknown new materials. In the natural world, su...
Researchers Integrate Diamond/Boron Nitride Crystalline Layers for Use in High-Power Devices
Researchers Integrate Diamond/Boron Nitride Crystalline Layers High-Power Devices
2016/5/19
We have created a new state of BN (named Q-BN) through rapid melting and super undercooling and quenching by using nanosecond laser pulses. Phase pure c-BN is formed either by direct quenching of supe...
Micron-scale d13C determination by NanoSIMS in a Juina diamond with a carbonate inclusion
sub-lithospheric diamonds Juina carbonate lower mantle peridotite eclogite
2017/4/10
Juina diamonds present a wide spectrum of mineral inclusions, covering both peridotitic and eclogitic composition.
Among the most rare inclusions, carbonates are interpreted as an evidence of deep re...
Researchers Find New Phase of Carbon,Make Diamond at Room Temperature
Researchers Carbon Diamond Room Temperature
2015/12/8
We report the discovery of new phase of carbon (referred to as Q-carbon) and address fundamental issues related to direct conversion of carbon into diamond at ambient temperatures and pressures in air...
The purpose of this article is to prove the relative consistency of certain statements about open colorings with 2ℵ0 < 2ℵ1. In particular both OCA and the statement that every 1-1 function...

DIAMOND AGGREGATION
2015/8/14
Internal diffusion-limited aggregation is a growth model based on random walk in Zd. We study how the shape of the aggregate depends on the law of the underlying walk, focusing on a family of walks in...
Depth profiling analysis of solar wind helium collected in diamond-like carbon film from Genesis
solar wind depth profile helium NASA Genesis mission post-ionization
2017/4/10
The distribution of solar-wind ions in Genesis mission collectors, as determined by depth profiling analysis, constrains
the physics of ion-solid interactions involving the solar wind. Thus, they pro...
Non-orthogonal version of the arbitrary polygonal C-grid and a new diamond grid
Non-orthogonal version arbitrary polygonal C-grid
2014/12/18
Quasi-uniform grids of the sphere have become
popular recently since they avoid parallel scaling bottlenecks associated with the poles of latitude–longitude grids.
DISTORTION DISTRIBUTION AND CONVERGENCE ANALYSIS OF SPHERICAL DIAMOND DISCRETE GRIDS

Gyroscopes nitrogen-vacancy centers diamond Atomic Physics
2012/5/17
We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy centers in diamond. In one scheme, rotation of the nitrogen-vacancy symmetry axis will induce Berry's phase ...
