Variable coordination of amine functionalised N-heterocyclic carbene ligands to Ru, Rh and Rr: C-H and N-H activation and catalytic transfer hydrogenation [PDF]

open access: yes, 2011
Chelating amine and amido complexes of late transition metals are highly valuable bifunctional catalysts in organic synthesis, but complexes of bidentate amine–NHC and amido–NHC ligands are scarce.

Non-Cyanide Silver as a Substitute for Cyanide Processes [PDF]

open access: yes, 2002
Since the mid 1800s, silver has been deposited from a cyanide-based formulation on a commercial basis. Commercial non-cyanide silver plating solutions were first made generally available in the late 1970s, and yet today the vast majority, and nearly ...

Photoinitiated oxidative addition of CF3I to gold(I) and facile aryl-CF3 reductive elimination. [PDF]

open access: yes, 2014
Herein we report the mechanism of oxidative addition of CF3I to Au(I), and remarkably fast Caryl-CF3 bond reductive elimination from Au(III) cations. CF3I undergoes a fast, formal oxidative addition to R3PAuR (R = Cy, R = 3,5-F2-C6H4, 4-F-C6H4, C6H5, 4 ...

Facile Preparation of Silver Halide Nanoparticles as Visible Light Photocatalysts

open access: yesNanomaterials and Nanotechnology, 2015
In this study, highly efficient silver halide (AgX)-based photocatalysts were successfully fabricated using a facile and template-free direct-precipitation method. AgX nanoparticles, which included silver chloride (AgCl), silver bromide (AgBr) and silver

Localized surface plasmon effects on the photophysics of perovskite thin films embedding metal nanoparticles [PDF]

open access: yes, 2020
Herein we provide direct experimental evidence that proves that the photophysical properties of thin methylammonium lead iodide perovskite films are significantly enhanced by localized surface plasmon resonances (SPRs). Observations are well supported by

Iodine speciation in a silver-amended cementitious system

open access: yesEnvironment International, 2019
Silver-impregnated zeolite (AgIZ) has been used for removing radioiodine from contaminated groundwater and nuclear waste streams and the worldwide inventory of such secondary waste is rapidly increasing. The objective of this study was to 1) quantify the

Variations in β(T)-function due to addition of LiI-4AgI system

open access: yesUniversitas Scientiarum, 2017
Impedance spectroscopy measurements of the LiI-4AgI samples, in the frequency range 20 Hz{1 MHz, and in the temperature range between 353 K and 378 K were made. Both pure and lithium-doped silver iodide showed blocking phenomena in the electrodes and the

Crystalline forms of silver iodide II: Determination of phase transformations [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
In order to obtain appropriate forms of AgI (β- and γ-), a procedure was developed to synthesize AgI at room temperature (23°C), whereby samples of varying crystallographic purity and of varying crystallographic contents of the different forms were ...

Chemical Stabilization of Perovskite Solar Cells with Functional Fulleropyrrolidines. [PDF]

open access: yes, 2017
While perovskite solar cells have invigorated the photovoltaic research community due to their excellent power conversion efficiencies (PCEs), these devices notably suffer from poor stability. To address this crucial issue, a solution-processable organic
