Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Influence of Phosphorus and Cell Geometry on the Fractionation of Sulfur Isotopes by Several Species of Desulfovibrio during Microbial Sulfate Reduction

Frontiers in Microbiology, 2017
We investigated the influence of organic substrates and phosphate concentration on the rates of dissimilatory microbial sulfate reduction and the 34S/32S isotopic fractionation produced by several Desulfovibrio species.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Stability of the marine nitrogen cycle over the past 165 million years

Nature Communications
Nitrogen and phosphorus are the two macro-nutrients that limit biological productivity in the ocean. While the supply of P depends on geological processes, N is biologically supplied from an inexhaustible atmospheric source, but can be limited by micro ...

Multidimensional Engineering Enabling Rate‐Matched C−N Coupling for Efficient Organonitrogen Electrosynthesis

EcoEnergy, EarlyView.
This review introduces rate matching as a unifying design principle for efficient electrochemical C−N coupling and highlights multidimensional engineering of catalysts, interfaces, and reactors to synchronize the generation of carbon‐ and nitrogen‐containing intermediates, balance their surface coverages, maximize C−N bond formation, and enable ...

Elemental and Isotopic Yields from T Coronae Borealis: Predictions and Uncertainties

The Astrophysical Journal
T Coronae Borealis (T CrB) is a symbiotic recurrent nova system expected to undergo its next outburst within the next 2 yr. Recent hydrodynamic simulations have predicted the nucleosynthetic yields for both carbon–oxygen (CO) and oxygen–neon (ONe) white ...
