Operando insights into correlating CO coverage and Cu-Au alloying with the selectivity of Au NP-decorated Cu2O nanocubes during the electrocatalytic CO2 reduction

Duncan Thomas Lindsay Alexander, Daniele Casari

Electrochemical reduction of CO2 (CO2RR) is an attractive technology to reintegrate the anthropogenic CO2 back into the carbon cycle driven by a suitable catalyst. This study employs highly efficient multi-carbon (C2+) producing Cu2O nanocubes (NCs) decora ...

Influence of Dimensionality on the Charge Density Wave Phase of 2H-TaSe2

Helmuth Berger

Metallic transition metal dichalcogenides like tantalum diselenide (TaSe2) exhibit exciting behaviors at low temperatures, including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to catalog influen ...

Push-Pull Effect of Terpyridine Substituted by Triphenylamine Motive-Impact of Viscosity, Polarity and Protonation on Molecular Optical Properties

Etienne Christophe Socie, Oliviero Cannelli

The introduction of an electron-donating triphenylamine motive into a 2,2',6',2''-terpyridine (terpy) moiety, a cornerstone molecular unit in coordination chemistry, opens new ways for a rational design of photophysical properties of organic and inorganic ...

Two-Dimensional Transition Metal Carbides and Nitrides (MXenes): Synthesis, Properties, and Electrochemical Energy Storage Applications

Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh

A family of 2D transition metal carbides and nitrides known as MXenes has received increasing attention since the discovery of Ti3C2 in 2011. To date, about 30 different MXenes with well-defined structures and properties have been synthesized, and many mor ...

Selective hydrogenation of 2-methyl-3-butyn-2-ol over Pd-nanoparticles stabilized in hypercrosslinked polystyrene: Solvent effect

Lioubov Kiwi

Selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-butene-2-ol (MBE) over Pd supported on hypercrosslinked polystyrene was studied in polar (ethanol, isopropanol, water) and non-polar (cyclohexane, toluene, octane, hexane, heptane and m-x ...

Linear and Time-Resolved THz Spectroscopy of Photonic and Charge Transporting Systems

Jan Cornelius Brauer

Photo-induced charge separation and charge transport are fundamental processes in many energy conversion techniques, where light is converted into chemical energy (PEC), into electrical energy (solar cells) or in the opposite sense if electrical energy is ...

Near-field mapping of quantum dot emission from single-photonic crystal cavity modes

Romuald Houdré, Nicolas Le Thomas, Laurent Balet

We directly investigate, by means of near-field spectroscopy, the spatial distribution of the optical cavity modes of 2D photonic crystal microcavities. Numerical simulations confirm that the photoluminescence maps of quantum dots embedded in the photonic ...
