Theory of double-kink nucleation in dilute BCC alloys
William Curtin, Alireza Ghafarollahi
Yielding in pure BCC metals and dilute substitutional alloys occurs by double-kink nucleation and propagation along screw dislocations. At low temperatures, the yield stress is controlled by double-kink nucleation. Here, an analytical statistical model is ...
PERGAMON-ELSEVIER SCIENCE LTD2020Efficient Hydrogen Oxidation Catalyzed by Strain-Engineered Nickel Nanoparticles
Xile Hu, Pascal Alexander Schouwink, Weiyan Ni, Teng Wang
The hydroxide-exchange membrane fuel cell (HEMFC) is a promising energy conversion device. However, the development of HEMFC is hampered by the lack of platinum-group-metal-free (PGM-free) electrocatalysts for the hydrogen oxidation reaction (HOR). Now, a ...
WILEY-V C H VERLAG GMBH2020Impact of oxygen content in powders on the morphology of the laser molten tracks in preparation for additive manufacturing of silicon
Patrik Willi Hoffmann, Lucas Güniat, Marc Leparoux
Powder additive pulsed Nd:YAG laser (wavelength 1064 nm), with the aim of preparing AM of such material. The influence of oxygen content in the initial silicon powders on the continuous tracks morphology was investigated. It was found that the initial oxyg ...
ELSEVIER2020Revealing Exciton and Metal–Ligand Conduction Band Charge Transfer Absorption Spectra in Cu-Zn-In-S Nanocrystals
Jacques-Edouard Moser, Etienne Christophe Socie, Brener Rodrigo De Carvalho Vale
Copper indium sulfide quantum dots (QDs) have attracted substantial attention in recent years due to environmental issues and diverse applications. We report the synthesis and characterization of copper-zinc-indium-sulfide (CZIS) QDs and CZIS treated with ...
20201D Amorphous Tungsten-Based Ternary Refractory Metal Sulfides for Catalytic Hydrogen Evolution at Soft Interfaces
Transition metals incorporated into molybdenum sulfide and tungsten sulfide matrixes are promising candidates for hydrogen evolution due to the unique chemical and physical properties. Here, we first describe a general strategy for the synthesis of rod-lik ...
WILEY-V C H VERLAG GMBH2019The role of malachite nanorods for the electrochemical reduction of CO2 to C-2 hydrocarbons
Emad Oveisi, Jie Zhang, Kun Zhao, Mariana Spodaryk
The electrochemical reduction of CO2 to higher hydrocarbons is a very challenging process that has high potential for the storage of large amounts of renewable energy with a high gravimetric and volumetric energy density. The distribution of hydrocarbons f ...
