Targeting membrane contact sites to mediate lipid dynamics: innovative cancer therapies.

Membrane contact sites (MCS) are specialized regions where organelles are closely interconnected through membrane structures, facilitating the transfer and exchange of ions, lipids, and other molecules. This proximity enables a synergistic regulation of cellular homeostasis and functions. The formation and maintenance of these contact sites are governed by specific proteins that bring organelle membranes into close apposition, thereby enabling functional crosstalk between cellular compartments.

Hole-Injection Layer-Free Perovskite Light-Emitting Diodes.

In this study, a dual-source vapor evaporation method was employed to fabricate the high-quality CsPbBr thin films with a good crystalline and high surface coverage. Temperature-dependent and excitation power-dependent photoluminescence measurements were performed to study the optical properties of the CsPbBr material. Further, based on the experimental data, the temperature sensitivity coefficient of band gap and exciton binding energy were estimated.

Vapor-Assisted Solution Approach for High-Quality Perovskite CHNHPbBr Thin Films for High-Performance Green Light-Emitting Diode Applications.

The vapor-assisted solution method was developed to prepare high-quality organic-inorganic halide perovskite CHNHPbBr (MAPbBr) thin films. We detailedly investigated the effect of evaporation time and temperature of MABr powder on the microstructure, crystallinity, and optical characterizations of MAPbBr thin films, and a controllable morphology evolution with varying surface coverage was observed. Temperature-dependent and time-resolved photoluminescence measurements were carried out to investigate the optical transition mechanisms and carrier recombination dynamics of MAPbBr thin films.
