Optoelectronic or photovoltaic device with metal halide perovskite film treated by passivating agent
Michael Graetzel, Shaik Mohammed Zakeeruddin, Lukas Pfeifer, Anurag Krishna
This invention relates to an optoelectronic or photovoltaic device comprising a perovskite or metal halide perovskite film treated by one or more compounds of formula (I): ((R1-NH(R2)-R3)+)nW (I), wherein n is an integer selected from 1, 2, or 3; R1, R2, R ...
2023Ni-Based Nanoparticles Catalyzed Hydrodeoxygenation of Ketones, Ethers, and Phenols to (Cyclo) Aliphatic Compounds
Paul Joseph Dyson, Mingyang Liu, Xiang Li, Yelin Hu, Matthias Beller
Catalytic hydrodeoxygenation is of prime importance in the valorization of biomass-based feedstocks to produce essential chemicals and fuels. To carry out this process in a more cost-effective and sustainable manner, the use of 3D-metal-based nanostructure ...
Washington2023Resolving the charging paradox of neat oil droplets in water
The thesis covers the series of questions regarding the molecular structure and charge of oil nanodroplets in water. This work proposes a mechanism responsible for the stabilization of oil nanodroplets in water, which does not involve OH- adsorption. First ...
EPFL2022Structures of the (Imidazole)(n)H+ ... Ar (n=1,2,3) complexes determined from IR spectroscopy and quantum chemical calculations ...
Here, we present new cryogenic infrared spectra of the (Imidazole) H-n(+) (n=1,2,3) ions. The data was obtained using helium tagging infrared predissociation spectroscopy. The new results were compared with the data obtained by Gerardi et al. (Chem. Phys. ...
SPRINGER/PLENUM PUBLISHERS2022Radiative cooling of carbon cluster anions C-2n+1(-) (n=3-5)
Radiative cooling of carbon cluster anions C(2n+1)(-)C2n+1- (n = 3-5) is investigated using the cryogenic electrostatic ion storage ring DESIREE. Two different strategies are applied to infer infrared emission on slow (milliseconds to seconds) and ultraslo ...
SPRINGER2020Multiple 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 ...
2020Correlation between Optical Activity and the Helical Molecular Orbitals of Allene and Cumulenes
Helical frontier molecular orbitals (MOs) appear in disubstituted allenes and even-n cumulenes. Chiral molecules are optically active, but while these molecules are single-handed chiral, p-orbitals of both helicities are present. Here we computationally ex ...
AMER CHEMICAL SOC2020Cross-Reactive Alginate Derivatives for the Production of Dual Ionic−Covalent Hydrogel Microspheres Presenting Tunable Properties for Cell Microencapsulation
Sandrine Gerber, Aurélien Bornet, François Rémi Pierre Noverraz, Luca Szabó
The production of hydrogel micropsheres (MS) presenting physical, mechanical, and biological properties which can be modulated by their chemical composition is required to enlarge the panel of biomaterials for cell transplantation therapies. Functionalizat ...
2019Electric-Field-Driven Direct Desulfurization
Klaus Kern, Hagen Klauk, Uta Schlickum, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel
The ability to elucidate the elementary steps of a chemical reaction at the atomic scale is important for the detailed understanding of the processes involved, which is key to uncover avenues for improved reaction paths. Here, we track the chemical pathway ...
Amer Chemical Soc2017Conductive framework of inverse opal structure for sulfur cathode in lithium-sulfur batteries
Hua Wu, Xiaopeng Huang, Lu Jin
As a promising cathode inheritor for lithium-ion batteries, the sulfur cathode exhibits very high theoretical volumetric capacity and energy density. In its practical applications, one has to solve the insulating properties of sulfur and the shuttle effect ...
