Sentences with phrase «with gold atoms»
Not exact matches
But the atomic structures of the clusters fluctuated under the heat treatment, switching back and forth between two main atom - configurations («isomers»): these were a face - centred cubic structure, similar to a small piece of bulk gold, and a decahedral arrangement with a symmetry forbidden in an extended crystal.

The just published research describes how single gold atoms dispersed on non-reactive supports based on silica materials can be stabilized with alkali ions.
The spin - valve consisted of two ferromagnetic cobalt layers, one superconductive niobium layer with thickness of approximately 150 atoms and a layer of gold.
His research has shown that the catalytic property of gold clusters can even change along with the configuration of atoms in those clusters.
Unlike most accelerators, which smash together simple particles like individual protons, RHIC accelerates clusters of hundreds of gold atoms — with 79 protons and neutrons in each gold nucleus — to 99.99 percent the speed of light.
The smallest particles have metal cores of only 1 - 2 nm with a few tens to a couple of hundred gold atoms.
When mixed and annealed, the tetrahedral arrays formed superlattices with long - range order where the positions of the gold nanoparticles mimics the arrangement of carbon atoms in a lattice of diamond, but at a scale about 100 times larger.
Through more symmetrical fission, with two fragments having nearly the same number of gold atoms and ligands.
In addition, gold clusters with the phenyl - containing ligand fragmented through a wide range of dissociation channels involving the loss of gold atoms as well as activation of the phosphorus - carbon bonds of the ligands.
Furthermore, theoretical calculations on diphosphine capped gold clusters often involve the substitution of simpler hydrogen atoms in the place of computationally demanding substituents such as phenyl groups with the assumption that the substitution does not alter the stability of the cluster.
Methods: Diphenylphosphine ligands, which consist of two phenyl (C6H5) substituted phosphorus centers separated by a carbon chain of variable length, produce gold clusters with extremely narrow distributions in size; that is, the synthesis route produces a large quantity of clusters with the same number of gold atoms as well as a small number of clusters with similar numbers of atoms.
They replaced particular carbon atoms in the hexagonal lattice with boron and nitrogen atoms using surface chemistry, by placing suitable organic precursor compounds on a gold surface.
The algorithm rediscovered the known property that gold nanoclusters with even number of atoms are semiconducting, whereas those with an odd number of atoms are metallic.
Scientists at Western University [Ontario, Canada] have discovered that a small molecule created with just 144 atoms of gold can increase solar cell performance by more than 10 per cent.
The two - disc Justice League Action: Season 1 Part 1 is packed with a star - studded acting roster, including Mark Hamill (The Joker, Swamp Thing), nine - time Emmy Award winner Carl Reiner (The Wizard), Emmy & Golden Globe winner James Woods (Lex Luthor), two - time Emmy winner Jon Cryer (Felix Faust), Golden Globe winner Christian Slater (Deadshot), Sean Astin (Shazam), Ken Jeong (Toyman), Diedrich Bader (Booster Gold), Andy Richter (Chronos), Jake T. Austin (Blue Beetle), Mena Suvari (Killer Frost), Lacey Chabert (Zatanna), Jerry O'Connell (The Atom), and Patton Oswalt (Space Cabbie).
As shown in the images, the two Windows 8.1 tablet sports an ultra slim design along with an elegant satin gold matte finish and rounded edges, and come equipped with Intel Atom quad - core processor, up to 64 GB internal storage, a bright HD multi-touch display with 1280 x 800 pixels resolution, and 1.2 - megapixel front - facing camera as well 5 - megapixel rear camera with autofocus.
I am just about convinced you can make any chemical starting with any other chemical if the atomic constituents add up (right number of H, C, O atoms, etc — still can not make gold from lead) if you have the right conditions and ADD ENOUGH ENERGY.
