Investigation of Reaction Kinetics of the Selective Hydrogenation of a Terminal Alkyne Under Industrially Relevant Conditions With Benchtop NMR Spectroscopy

Magnetic Resonance in Chemistry, Volume 64, Issue 6, Page 539-554, June 2026.
The combination of 1H benchtop NMR and a quantum‐mechanical Bayesian qNMR method enables rapid, quantitative monitoring of heterogeneous catalyzed hydrogenations under industrially relevant conditions, including elevated temperature, pressure, and undiluted feeds.

Investigating the role of a conserved hydrophobic pocket of gp41 in the anti‐HIV activity of fusion inhibitors

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Membrane fusion between HIV and host cells requires interaction between the N‐terminal and C‐terminal repeat regions (NHR and CHR) of the gp41 envelope subunit. A deep hydrophobic pocket (HP) on the surface of NHR is considered crucial in this interaction.

Optimization of Turbidity Removal in Water Using Chemically Modified Tannins From Brazilian Species

Water Environment Research, Volume 98, Issue 6, June 2026.
Cationized tannins from Stryphnodendron adstringens and Mimosa tenuiflora efficiently removed water turbidity under optimized conditions. These natural coagulants demonstrated nearly 100% clarification, offering sustainable alternatives for water treatment.

Application of Standard HSQC-ME Pulse Sequence on Benchtop NMR Devices for Quantitative Applications

Concepts in Magnetic Resonance: Part A, Bridging Education and Research
The heteronuclear single quantum correlation (HSQC) NMR method is widely used for the structural characterization of complex mixtures. In this study, the application range of multiplicity-enhanced HSQC (HSQC-ME) spectroscopy was broadened to quantitative
