This dissertation presents the first measurement of electron-muon azimuthal correlations at the PHENIX experiment at RHIC in 200 GeV proton-proton and deuteron-gold collisions. Electron-muon pairs result from the semileptonic decay of D mesons, which come from correlated charm pairs. The pairs are...
The potential toxicity of ligand-protected nanoparticles (NPs) on biological targets is crucial for their clinical translation. A number of studies are aimed at investigating the molecular mechanisms shaping the interactions between synthetic NPs and neu
Gold, or alloys of gold and palladium, are applied as conductive coating to biological specimens and other non-conducting materials such as plastics and glass to be viewed in a scanning electron microscope. The coating, which is usually applied by sputtering with an argon plasma, has a triple ...
Traditionally, gold in the universe is thought to have formed by the r-process (rapid neutron capture) in supernova nucleosynthesis,[54] but more recently it has been suggested that gold and other elements heavier than iron may also be produced in quantity by the r-process in the collision ...

framework of1through the strong Au···H–C interactions, as found in the X-Ray structures and NMR profiles, presumably assisted by the above-mentioned cluster-π interaction. Discussion We have demonstrated that a cationic four-electron Au6cluster ([Au6]2+) can interact with proximal un...
which decays by proton emission with a half-life of 30 µs. Most of gold's radioisotopes with atomic masses below 197 decay by some combination of proton emission, α decay, and β+ decay. The exceptions are 195 Au , which decays by electron capture, and 196 Au , which decays most ...
A gold nucleus (197/79)Au absorbs a neutron of nearly zero kinetic energy, and emits an electron. A: What is produced? B: How much energy is released in this reaction, in eV? Alpha particles which have a charge +2e and mass 6.64 x 10^(-2...
Every atom in the universe is just like a little gyroscope: it's got all these electrons spinning around the nucleus, and they have a gyroscopic effect, which is the effect we call inertia and mass. We have one nucleus with a proton and a neutron and one el...
Both the diaminocyclohexane and ethylenediamine ligands as well as derivatives thereof bind to the central gold(III) atom in a bidentate manner. The nitrogen atoms in the diamino groups act as electron donor atoms that the gold(III) atom is coordinated. In other words, the gold(III) atom is...
