Fluorescent Dyes for Probing Intracellular and Subcellular Polarity
Chemistry–Methods, Volume 6, Issue 1, January 2026.Fluorescent probes are crucial tools for measuring cellular microenvironment polarity, a parameter that influences physiological organelle function and diseases such as cancer. This text details the probes' physicochemical principles, intracellular targeting strategies, and key photophysical parameters for polarity estimation.

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.Abstract Urbanization generates significant amounts of sewage sludge (SS), with relatively high concentrations of plant nutrients such as phosphorus (P). When biochemically stabilized by composting, SS (composted sewage sludge [CSW]) can serve as a sustainable P source in agriculture, supporting a circular economy and reducing agriculture's dependence ...

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.Our results contribute to understanding of carbon allocation dynamics in Mediterranean pine reforestation under climate change. Following the optimum allocation principle, carbon investment to aboveground organs increased dynamically in less drought‐tolerant species and under cooler and more humid conditions.

Rhombohedral R3c to orthorhombic Pnma phase transition induced by Y-doping in BiFeO3 [PDF]
, 2018 In this work we study, by means of ab initio calculations, the structural, electronic and magnetic properties of Y-doped BiFeO3 compounds. We determine that there is a morphotropic phase boundary at an yttrium concentration of , where the structure ...
