Water‐Dispersible Ruthenium Nanocatalyst for Carbonyl Reduction With D2 or T2 in Aqueous Media

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We report the synthesis and characterization of water‐dispersible ruthenium nanoparticles that catalyze the reductive deuteration and tritiation of carbonyl compounds in aqueous media, enabling efficient access to a broad range of isotopically labeled polar molecules, including cyclic peptides, antibody‐drug conjugate linkers, pegylated derivatives ...

Insights into impact of polar protic and aprotic solvents on bioactive features of 3-(Dimethylaminomethyl)-5-nitroindole: A DFT study and molecular dynamics simulations.

PLoS ONE
Polar protic and aprotic solvents can effectively simulate the maturation of breast carcinoma cells. Herein, the influence of polar protic solvents (water and ethanol) and aprotic solvents (acetone and DMSO) on the properties of 3-(dimethylaminomethyl)-5-

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

Small, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Distinct Solvent Effects on Dispersibility and Photoinduced Hydrogen Release of Hydrogen Boride Sheets

Small, EarlyView.
Hydrogen boride (HB) sheets exhibit strongly solvent‐dependent dispersion and photoinduced hydrogen release. HB‐sheet dispersibility depends on solvent‐dependent interactions, whereas hydrogen release is more strongly associated with the hydrogen‐bonding character of the solvent.

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

Small, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Bromination of Alkenes and Related Compounds by Use of Benzyltrimethylammonium Tribromide in Aprotic and Protic Solvents

, 1988
The reaction of alkenes and related compounds (1) with benzyltrimethyl-ammonium tribromide (BTMA Br_3) in aprotic solvents such as dichloromethane and chloroform gave 1, 2-dibromo adducts in fairly good yields.
