Multiple dehydrogenation reactions of negative ions in low pressure silane plasma chemistry

Christoph Hollenstein, Alan Howling, Antoine Descoeudres

Micro-particle formation in low pressure silane (SiH4) plasmas has been of technical interest and concern for at least 40 years. Negative ion plasma chemistry is a candidate for the initial nucleation, which has been extensively studied both experimentally ...

Data-Driven Model for the Dynamic Characteristics of O-Rings for Gas Bearing Supported Rotors

Jürg Alexander Schiffmann, Philipp Kaspar Bättig

The measurement results of various nitrile butadiene rubber (NBR) O-Ring sizes are pre-sented, and reduced-order models are developed in order to predict the stiffness and damping coefficient as a function of O-Ring geometry, Shore hardness, squeeze, and e ...

Silicon Corrosion in Neutral Media: The Influence of Confined Geometries and Crevice Corrosion in Simulated Physiological Solutions

Stefano Mischler, Patrik Schmutz, Roland Hauert, Emilija Ilic

Silicon (Si) based implantable components are widely used to restore functionalities in the human body. However, there have been reported instances of Si corroding after only a few years of implantation. A key parameter often overlooked when assessing Si s ...

Bond selective dissociation of methane (CH3D) on the steps and terraces of Pt(211)

Rainer Beck, Ana Gutiérrez González, Fleming Crim

The dissociative chemisorption of singly deuterated methane (CH3D) has been studied on the steps and terraces of a Pt(211) surface by quantum state resolved molecular beam methods. At incident translational energy (Et) below 50 kJ/mol, CH3D dissociates onl ...

Soft-Sphere Continuum Solvation in Electronic-Structure Calculations

Nicola Marzari, Oliviero Andreussi

We present an implicit solvation approach where the interface-between the quantum-mechanical solute and the surrounding environment is, described by a fully continuous permittivity built up with atomic-centered "soft" spheres. This approach combines many o ...

Palladium-Catalyzed Three-Component Reaction of Propargyl Carbonates, Isocyanides, and Alcohols or Water: Switchable Synthesis of Pyrroles and Its Bicyclic Analogues

Qian Wang, Jieping Zhu, Guanyinsheng Qiu

In the presence of a catalytic amount of Pd(OAc)2 and a stoichiometric amount of tert-butylamine, the reaction of propargyl carbonates, isocyanides, and alcohols afforded polysubstituted aminopyrroles in good yields. Using water as a nucleophile instead of ...

Abatement of Polychoro-1,3-butadienes in Aqueous Solution by Ozone, UV Photolysis, and Advanced Oxidation Processes (O-3/H2O2 and UV/H2O2)

Urs von Gunten, Minju Lee, Silvio Canonica

The abatement of 9 polychloro-1,3-butadienes (CBDs) in aqueous solution by ozone, UV-C(254 nm) photolysis, and the corresponding advanced oxidation processes (AOPs) (i.e., O-3/H2O2 and UV/H2O2) was investigated. The following parameters were determined for ...

The Molecular Mechanism of the Catalase-like Activity in Horseradish Peroxidase

Ursula Röthlisberger, Pablo Campomanes Ramos

Horseradish peroxidase (HRP) is one of the most relevant peroxidase enzymes, used extensively in immunochemistry and biocatalysis applications. Unlike the closely related catalase enzymes, it exhibits a low activity to disproportionate hydrogen peroxide (H ...

Hydrothermally-treated Na-X as efficient adsorbents for butadiene removal

Lioubov Kiwi, Jeremy Luterbacher, Florent Emmanuel Héroguel, Guillaume Bastien Baur, Jonathan Spring

An efficient adsorbent for butadiene was synthesized via soft hydrothermal treatment (2 h in boiling water followed by 1 h calcination at 573 K) of industrial Na-X. The adsorption capacity of the zeolite was studied in the low concentration range (20–300 p ...
