Kinetics and mechanism of the reaction between silver(III) and thiourea in aqueous alkaline mediaMonte Carlosimulationadsorptionpotential barriersThe tetrahydroxoargentate(III) ion, Ag(OH) 4 , is rapidly reduced by thiourea (tu) in accordance with the three term rate law rate = { k 1+( k 2...
Tertiary propargylic alcohols 15 undergo cycloaddition with thioamides 16 in the presence of silver triflate as the catalyst to give substituted thiazoles 20 with complete regioselectivity. This reaction is in contrast to the corresponding scandium-catalyzed version where the substrates are limited to ...

activation strategies are often associated with highly energy-demanding processes, as well as with the use of solvents that often times are not friendly with the environment and are commonly associated with costly and time-consuming procedures for the preparation and isolation of t...
Silver thioether chemistry: Synthesis, X-ray crystal structure and redox properties of [Ag([18]aneS6)]+ ([18]aneS6 = 1,4,7,10,13,16-hexathiacyclooctadecane) Reaction of AgNO 3 with 1 molar equivalent of [18]aneS 6 ([18]aneS 6 = 1,4,7,10,13,16-hexathiacyclooctadecane) in wa...
HER. Density functional theory (DFT) calculations have been utilized to evaluate the catalytic hydrogen evolution reaction activity of four proposed bare systems: fullerene (C24), calcium encapsulated fullerene (CaencC24), nickel-doped calcium encapsulated fullerene (NidopCaencC24), and silver decorated...
In this work, three plastic film products commonly used as commodity thermoplastic articles were analysed with the aim of characterizing their thermal behaviour and stability. The test specimens were subjected to a series of analytical tests to confirm their biodegradable nature. The specimens ranged be...
The technique of step-by-step optically-induced solid state reaction of Ag into As33S67 amorphous films, which has allowed the design of films with known silver concentrations, is reported. The host, As33S67 films, were photo-doped by consecutive dissolution of a 10 nm layer of silver, ...
