Correlated Ground-based and IUE Observations [PDF]

The value of coordination among different observers particularly, those working in different wavelength regions is highlighted. This coordination is more important among observers of comets than among observers of almost any other class of astronomical ...

Flavodiiron proteins associate pH‐dependently with the thylakoid membrane for ferredoxin‐1‐powered O2 photoreduction

New Phytologist, Volume 246, Issue 5, Page 2084-2101, June 2025.
Summary Flavodiiron proteins (FDPs) catalyse light‐dependent reduction of oxygen to water in photosynthetic organisms, creating an electron sink on the acceptor side of Photosystem I that protects the photosynthetic apparatus. However, ambiguity about the electron donor(s) remains, and the molecular mechanisms regulating FDP activity have remained ...

Stomata‐Photosynthesis Synergy Mediates Combined Heat and Salt Stress Tolerance in Sugarcane Mutant M4209

Plant, Cell &Environment, Volume 48, Issue 6, Page 4668-4684, June 2025.
ABSTRACT Sugarcane (Saccharum officinarum L.) is an economically important long‐duration crop which is currently facing concurrent heat waves and soil salinity. The present study evaluates an inducible salt‐tolerant sugarcane mutant M4209, developed via radiation‐induced mutagenesis of elite check variety Co 86032, under heat (42/30°C; day/night), NaCl

Photoinduced Hydrogen Evolution Catalyzed by Co(II) Complexes of N5‐Donor Ligands

Chemistry – A European Journal, Volume 31, Issue 28, May 19, 2025.
Cobalt(II) complexes of three related pentadentate ligands have been investigated as photoelectrochemical catalysts for proton reduction/hydrogen gas evolution in the presence of ruthenium, iridium, or copper‐based photosensitizers. Potential mechanisms for hydrogen evolution have been investigated by time‐resolved transient absorption spectroscopy and

Sand washing of oil spill–affected beaches using concentrated β-glucans obtained from residual baker's yeast

Heliyon
Valorization of residual yeast of the bakery industry for use in the remediation of oil-contaminated soils as an emulsifier is a biocompatible and effective process that will reduce environmental pollution. The aim of this study was to use concentrated β-

Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

ChemSusChem, Volume 18, Issue 10, May 19, 2025.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,
