The kinetics and mechanism of the title heterogeneous halogen exchange reactions of potential atmospheric importance have been studied under molecular flow conditions in a FEP Teflon-coated Knudsen flow reactor on HX (X = Cl, Br, I) - doped ice condensed f ...
We propose a new mechanism for the electroreduction of hydrogen in acidic media. The specific model and theoretical calculations are designed for the Pt(111) surface, because this is the only face that exhibits a clear first order phase transition. The bas ...
A new type of hydrogen dissociator for polarized atomic beams, based on a surface-wave discharge at 2.45 GHz, is described. We report dissociation-degree measurements as function of gas throughput, microwave power and oxygen fraction. A dissociation degree ...
Hydrogen-bonding strengths in the solid state are quantitatively determined by the accurate measurement of (15)N-(15)N J couplings using a straightforward 2D MAS NMR spin-echo approach. ...
The amino-amido-thiol AT (HS-(CH2)10-CO-NH-CH2-CH2-NH2)(HS-(CH2)10-CO-NH-CH2-CH2-NH2), adsorbed on Au(111), was studied by sum frequency generation (SFG) and IR reflection absorption spectroscopy in the CH2 stretching vibration region. The SFG and IR spect ...
We investigate the hydrogen related bonding structure in hydrogenated polymorphous silicon films (pm-Si:H) and hydrogenated microcrystalline silicon. Infra-red spectra reveal some new features for both kinds of films. namely new modes appearing in the stre ...
Pseudo-proline building blocks exert a dual functionality in enhancing and stabilizing the relevant polyproline II (PPII) conformation and increasing and optimizing van der Waals contacts and hydrogen bonding to the receptor mols. thus modifying affinity a ...
We report calculations of the electronic ground state potential energy surface (PES) of hydrogen peroxide covering, in an almost global fashion, all six internal degrees of freedom by two different ab initio techniques. Density functional theory (DFT) calc ...
A probe for amperometric measurement of dissolved hydrogen dissolved in a liq. contains an Pt indicating electrode and a metallic pseudoref. electrode, constituted of, preferably, Ag or Hg, with a deposit of oxide on the pseudoref. electrode, preferably, A ...
Hydrolysis and hydrogenation of [RhCl(tppms)(3)] (1) and trans-[RhCl(CO)(tppms(2)] (2) was studied in aqueous solutions in a wide pH range (2 < pH < 11) in the presence of excess TPPMS (3 -diphenylphosphinyl-benzenesulfonic acid sodium salt). In acidic sol ...
