Gradient Heating Epitaxial Growth Gives Well Lattice-Matched Mo2C-Mo2N Heterointerfaces that Boost Both Electrocatalytic Hydrogen Evolution and Water Vapor Splitting

An optimized approach to producing lattice-matched heterointerfaces for electrocatalytic hydrogen evolution has not yet been reported. Herein, we present the synthesis of lattice-matched Mo2C-Mo2N heterostructures using a gradient heating epitaxial growth ...

Catalyzing Bond-Dissociation in Graphene via Alkali-Iodide Molecules

Klaus Kern, Stephan Rauschenbach, Sabine Abb, Sven Alexander Szilagyi, Hannah Julia Ochner

Atomic design of a 2D-material such as graphene can be substantially influenced by etching, deliberately induced in a transmission electron microscope. It is achieved primarily by overcoming the threshold energy for defect formation by controlling the kine ...

Iodic acid, sulfuric acid and methanesulfonic acid collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Measurements of iodic acid, sulfuric acid and methanesulfonic acid concentration in the gas phase obtained with a nitrate chemical ionization mass spectrometer (we used an APi-TOF mass spectrometer produced by Tofwerk AG coupled with a Chemical ionization ...

Facile N-functionalization and strong magnetic communication in a diuranium(v) bis-nitride complex

Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Lucile Sylvie Danielle Chatelain, Luciano Barluzzi

Uranium nitride complexes are of high interest because of their ability to effect dinitrogen reduction and functionalization and to promote magnetic communication, but studies of their properties and reactivity remain rare. Here we have prepared in 73% yie ...

Z-Selective Synthesis of Vinyl Boronates through Fe-Catalyzed Alkyl Radical Addition

Xile Hu, Alexis Baptiste Cheseaux, Guido Barzanò

Z-Selective synthesis of vinyl boronates is challenging. This work describes Fe-catalyzed addition of alkyl radicals, formed by the corresponding alkyl halides, to ethynyl ethynylboronic acid pinacol ester that gives rise to Z-vinyl boronates in high stere ...

Stereoselective synthesis of alkenes via base-metal-catalyzed addition reactions to alkynes and activation of hydrogen peroxide and carbon dioxide by iron complexes

Fedor Zhurkin

Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...

Investigation of the RF efficiency of Inductively Coupled Hydrogen Plasmas at 1MHz

Minh Quang Tran, Stefano Mattei

The power requirements of RF heated sources for negative hydrogen ions in fusion are substantial, which poses strong demands on the generators and components of the RF circuit. Consequently, an increase of the RF coupling efficiency would be highly benefic ...

Reactions of hypoiodous acid with model compounds and the formation of iodoform in absence/presence of permanganate

Urs von Gunten, Jun Ma

The kinetics for the reactions of hypoiodous acid (HOI) with various phenols (phenol, 4-nitrophenol, 4-hydroxybenzoic acid), 3-oxopentanedioic acid (3-OPA) and flavone were investigated in the pH range of 6.0-11.0. The apparent second order rate constants ...

A new formation strategy of hybrid perovskites via room temperature reactive polyiodide melts

Michael Graetzel, Shaik Mohammed Zakeeruddin, Andrey Petrov

Here we introduce a new solvent-free preparation method for hybrid metal halide perovskites involving the direct reaction of metallic lead with polyiodide melts. We discovered new reactive polyiodide melts (RPMs) that can be prepared simply by adding eleme ...

Halide removal from aqueous solution by novel silver-polymeric materials

Urs von Gunten

The objective of this study was to analyze the behavior of a new material, silver-doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions a ...
