Advanced Energy and Sustainability Research, EarlyView.Less metal, more distance! The ReOx‐Pd/CeO2 catalyst, an active heterogeneous catalyst for the consecutive deoxydehydration and hydrogenation of vicinal diol, suffers a gradual loss of activity throughout its use due to the polymerization of monomeric ReOx active species.

The glutaminase-dependent acid resistance system. Qualitative and quantitative assays and analysis of its distribution in enteric bacteria [PDF]
, 2018 Neutralophilic bacteria have developed several strategies to overcome the deleterious effects of acid stress. In particular, the amino acid-dependent systems are widespread, with their activities overlapping, covering a rather large pH range, from 6 to

Bio-based nitriles from the heterogeneously catalyzed oxidative decarboxylation of amino acids.
ChemSusChem, 2015 The oxidative decarboxylation of amino acids to nitriles was achieved in aqueous solution by in situ halide oxidation using catalytic amounts of tungstate exchanged on a [Ni,Al] layered double hydroxide (LDH), NH4 Br, and H2 O2 as the terminal oxidant ...

Real-time observation of oxidation and photo-oxidation of rubrene thin films by spectroscopic ellipsometry [PDF]
arXiv, 2007 We follow in real-time and under controlled conditions the oxidation of the organic semiconductor rubrene grown on SiO_2 using spectroscopic ellipsometry. We derive the complex dielectric function epsilon_1 + i epsilon_2 for pristine and oxidized rubrene showing that the oxidation is accompanied by a significant change of the optical properties, namely

Shot-Peening of Pre-Oxidized Plates of Zirconium: Influence of Residual Stress on Oxidation [PDF]
, 2013 The present study deals with oxidation behavior under residual stress of shot-peened plates of "commercially pure" zirconium exposed for 30 min at 650 C. The influence of the shot-peening on a pre-oxidized material is presented. The results have been used to determine the influences of these chemical (preoxidation) and mechanical (shot-peening ...
