Chemical Kinetics of 2‐, 4‐, and 2,4‐Seleno‐Uracils at Low Temperatures: Tautomerizations and Rotamerizations on Inert Matrices

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Size Matters: Barrier Heights and Widths in the Kinetics Of Tautomerisation and Rotamerisation of Thiotropolone and Its Five‐ and Three‐Membered Cyclic Analogues

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...

Ginsenoside Rg1 Ameliorates LPS‐Induced Sepsis‐Associated Lung Injury in Mice via VEGFC/D‐VEGFR3 Signaling‐Mediated Lymphangiogenesis and Lymphatic Remodeling

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Sepsis‐induced acute lung injury (ALI) remains challenging to treat, with conventional anti‐inflammatory therapies offering limited efficacy. The lymphatic system is crucial for removing edema and inflammatory mediators, and its impairment can exacerbate lung injury.

Long‐Term Combined Application of Biochar and Chemical Fertilizers Enhances Potassium Supply Capacity in Continuous Cropping Soils

Land Degradation &Development, EarlyView.
ABSTRACT Sustaining soil potassium (K) supply in intensive continuous cropping systems is increasingly challenging because long‐term crop removal often exceeds the natural replenishment capacity of soil K‐bearing minerals, leading to progressive depletion of plant‐available K pools.

Supercritical Angle Fluorescence and Raman Techniques in Biophotonics

Laser &Photonics Reviews, EarlyView.
Supercritical angle fluorescence (SAF) microscopy and supercritical angle Raman (SAR) spectroscopy have emerged as powerful tools in the field of biophotonics, enabling high‐resolution imaging and spectroscopy of biological specimens near interfaces. This review article provides a comprehensive overview of the principles, techniques, applications, and ...
