Tandem catalysis enables chlorine-containing waste as chlorination reagents
Paul Joseph Dyson, Mingyang Liu, Xinbang Wu
Chlorinated compounds are ubiquitous. However, accumulation of chlorine-containing waste has a negative impact on human health and the environment due to the inapplicability of common disposal methods, such as landfill and incineration. Here we report a su ...
Berlin2024Optoelectronic 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 ...
2023Photocatalyzed [2σ + 2σ] and [2σ + 2π] Cycloadditions for the Synthesis of Bicyclo[3.1.1]heptanes and 5- or 6-Membered Carbocycles
Jérôme Waser, Matthew Wodrich, André Bossonnet
We report the use of photocatalysis for the homolytic ring-opening of carbonyl cyclopropanes. In contrast to previous studies, our approach does not require a metal cocatalyst or a strong reductant. The carbonyl cyclopropanes can be employed for both [2σ + ...
2023Autocatalysis and CO2: Carbon Capture and Utilization (CCU) Meets Natural Processes
Paul Joseph Dyson, Jorge Gustavo Uranga, Martin Hulla, Gabriela Gastelu
Autocatalytic reactions were proposed to play a key role at the beginning of life starting from the first reduction of CO2 to formate, acetate and C-1-C-4 hydrocarbons. In carbon capture and utilization (CCU) processes, the same reactions were demonstrated ...
Weinheim2023Rheological Properties of Ionically Crosslinked Viscoelastic 2D Films vs. Corresponding 3D Bulk Hydrogels
Esther Amstad, Gaia De Angelis
Ionically crosslinked hydrogels containing metal coordination motifs have piqued the interest of researchers in recent decades due to their self-healing and adhesive properties. In particular, catechol-functionalized bulk hydrogels have received a lot of a ...
AMER CHEMICAL SOC2023Photodegradation of biodegradable plastics in aquatic environments: Current understanding and challenges
Florian Frédéric Vincent Breider, Vinhteang Kaing
Direct photolysis and indirect photolysis are important abiotic processes in aquatic environments through which plastics can be transformed physically and chemically. Transport of biodegradable plastics in water is influenced by vertical mixing and turbule ...
2023Double-bond delocalization in non-alternant hydrocarbons induces inverted singlet-triplet gaps
Marc Hamilton Folkmann Garner, Jacob Terence Blaskovits
Molecules where the first excited singlet state is lower in energy than the first excited triplet state have the potential to revolutionize OLEDs. This inverted singlet-triplet gap violates Hund's rule and currently there are only a few molecules which are ...

ROYAL SOC CHEMISTRY2023Jahn-Teller effects in initial and final states: high-resolution X-ray absorption, photoelectron and Auger spectroscopy of allene
Majed Chergui, Camila Bacellar Cases Da Silveira, Rebecca Ann Ingle, Luca Longetti, Thomas Roland Barillot, Daniel Hollas, Ludmila Maria Diniz Leroy
Carbon K-edge resonant Auger spectra of gas-phase allene following excitation of the pre-edge 1s -> pi* transitions are presented and analysed with the support of EOM-CCSD/cc-pVTZ calculations. X-Ray absorption (XAS), X-ray photoelectron (XPS), valence ban ...
ROYAL SOC CHEMISTRY2023Hydrogen Storage by Reduction of CO2 to Synthetic Hydrocarbons
Noris André Gallandat, Wen Luo, Jie Zhang, Kun Zhao
The storage of renewable energy is crucial for the substitution of fossil fuels with renewable energy. Hydrogen is the first step in the conversion of electricity from renewable sources to an energy carrier. However, hydrogen is technically and economicall ...
