Eu-doped ZrO2 solid solutions have been synthesized in order to prepare proton conductors as water-enhancer additives for the WGS reaction. Elemental characterization has been carried out revealing homogeneous dopant distribution resulting in fluorite-type solid...

Photonic structuring improves colour purity of rare-earth nanophosphors

May 26, 2018 | Uncategorized

Nanophosphor integration in an optical cavity allows unprecedented control over both the chromaticity and the directionality of the emitted light, without modifying the chemical composition of the emitters or compromising their efficiency. Our approach opens a route...

Isolation of a Cationic Platinum(II) s-Silane Complex

Apr 26, 2018 | 2018, 2018, 2018, 2018, 2018

The platinum complex [Pt(ItBuiPr′)(ItBuiPr)][BArF] interacts with tertiary silanes to form stable (<0 °C) mononuclear PtII σ‐SiH complexes [Pt(ItBuiPr′)(ItBuiPr)(η1‐HSiR3)][BArF]. These compounds have been fully characterized, including X‐ray diffraction methods,...

Epimerization of glucose over ionic liquid/ phosphomolybdate hybrids: structure-activity relationship

Mar 26, 2018 | Uncategorized

The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose was studied. A clear evidence of structure–activity relationship was found. The inorganic part of the...

Selective catalytic synthesis of amino-silanesat part-per million catalyst loadings

Feb 26, 2018 | Uncategorized

Platinum(II) complex [Pt(ItBu0)(ItBu)][BArF4] (1a) is a highly active and selective catalyst in the dehydrocoupling of amines and silanes at part-per-million catalyst loadings (up to 10 ppm, 0.001 mol%), achieving the highest TON and TOF numbers reported in the...

Broad Scope Synthesis of Ester Precursors of Nonfunctionalized Chiral Alcohols Based on the Asymmetric Hydrogenation of α,β- Dialkyl-, α,β- Diaryl-, and α-Alkyl-β-aryl-vinyl Esters

Dec 26, 2017 | 2017

The catalytic asymmetric hydrogenation of trisubstituted enol esters using Rh catalysts bearing chiral phosphinephosphite ligands (P-OP) has been studied. Substrates covered comprise α,β-dialkyl, α-alkyl-β-aryl, and α,β-diarylvinyl esters, the corresponding...
