#Diamond-like coatings save fuel (Nanowerk News) Scientists already know how to coat components with diamond-like carbon to minimize friction.
which layers of carbon almost as hard as diamond can be applied on an industrial scale at high coating rates and with high thicknesses.
and thus more resistant to wear than conventional diamond-like coatings. Unfortunately, you cant just scrape off diamond dust and press it onto the component.
and the Diamond Light source in Oxfordshire, England. In the process, they discovered why the electrons are so fast and mobile.
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.
the team measured the effect of near-infrared light on thin layers of water by examining the friction on a diamond probe as it pushed through water
#Scientists Make Friction Disappear By Coating Diamonds With Graphene Diamonds are already one of the hardest natural substances known to science.
and diamond nanoparticles are also incredibly slippery, which can be useful if you want to reduce friction in a moving machine.
Scientists at Argonne National Laboratory recently announced that the combination of tiny bits of diamond with the two-dimensional graphene created tiny structures that had superlubricity--meaning that the friction between them
When the diamond nanoparticles came in contact with the thin sheets of graphene (carbon that's only an atom thick) the graphene rolled up around the diamond nanoparticles,
With the new graphene coating, the diamond particles could roll far more easily over a larger diamond-like surface that the researchers used as a testing ground.
and diamond that makes the superlubricity possible right now, but researchers hope that they can expand the property to other materials in the future. he knowledge gained from this study will be crucial in finding ways to reduce friction in everything from engines or turbines to computer hard disks and microelectromechanical systems,"nanoscientist Ani Sumant,
Together they formed Team Turquoise to make their hypothesis a reality. Co-creator Nell Bennett explained how doppel represents truly empathic wearable technology
Team Turquoise says prototype models have been tested successfully on hundreds of people. They say doppel was tested also independently by psychologists at Royal Holloway University of London;
Bilicki, along with the rest of Team Turquoise, believe doppel is a unique and game-changing addition to the burgeoning wearable technology market."
or nitrogen atoms embedded in diamond--would still benefit from using entangled photons to move quantum information around.
Nanoscale mirrored cavities that trap light around atoms in diamond crystals increase the quantum mechanical interactions between light and electrons in atoms.
and the Center for Functional Nanomaterials at the U s. Department of energy's Brookhaven National Laboratory, has demonstrated a new process to construct such diamond nanocavities in
and the Diamond Light source in Oxfordshire, England. In the process, they discovered why the electrons are so fast and mobile.
New insight into the fundamentals of solid state physics A team at HZB has carried out the first detailed study of how magnetic and geometric ordering mutually influence one another in crystalline samples of spinel.
The results were published in Physical Review B. Spinels consist of densely packed highly symmetrical planes of oxygen atoms (somewhat like a densely packed box of marbles) where different metallic elements are lodged in the spaces between them.
The embedded metal ions in the Ni1-xcuxcr2o4 spinel system cause a distortion of the crystal structure.
The HZB team has analysed now comprehensively the chromium-spinel system and have explained the complex phase diagram at a fundamental level for the first time.
The series begins with samples of pure nickel-chromium spinel (x=0; a green powder) and continues with increasing proportions of copper.
which lies far below room temperature for pure nickel-spinel as well as for copper-spinel.""We were able for the first time to determine the magnetic characteristics exactly
Peninsula of orthorhombic state At a mixture ratio of 85%nickel and 15%copper, the spinel system displays a kind of narrow peninsula of orthorhombic state in the phase diagram where the observed Anm
When the lubricant materials--graphene and diamond-like carbon (DLC)--slid against each other, the graphene began rolling up to form hollow cylindrical"scrolls"that helped to practically eliminate friction.
and diamond-like carbon on the other side. However, the knowledge gained from their study is perhaps even more valuable,
and Photonic Nano-Meta Technologies Inc. A nitrogen-vacancy center is an atomic-scale defect formed in the diamond lattice by substituting a nitrogen atom for a carbon atom
By constructing tiny irrorsto trap light around impurity atoms in diamond crystals, the team dramatically increased the efficiency with
and characterize the materials. he memory elements described in this research are the spin states of electrons in nitrogen-vacancy (NV) centers in diamond.
The NV consists of a nitrogen atom in the place of a carbon atom, adjacent to a crystal vacancy inside the carbon lattice of diamond.
These cavities, nanofabricated at Brookhaven by MIT graduate student Luozhou Li with the help of staff scientist Ming Lu of the CFN, consist of layers of diamond
In our case, we overcame the problem that hundred-nanometer-thick diamond membranes are too small and too uneven.
because silicon always adopt diamond-like structure but not honeycomb structures, he said. t also very unstable when exposed to oxygen.
forming a structure like a crystal rod with an embedded array of gems. Details of the new method are published in the journal Nature Materials.
