Cathodoluminescence of MAPbCl Halide Perovskite Single Crystal.

Chloride perovskites are semiconductors with a near-ultraviolet bandgap that are promising for applications in optoelectronics and photonics. One of the most studied representatives of this family is the methylammonium lead chloride MAPbCl (MA = CHNH). Low-temperature luminescence spectroscopy of this material demonstrates a complex emission structure.

Target-Oriented Synthesis of Triphenylphosphine Functionalized Carbon Dots with Negative Charge for ROS Scavenging and Mitochondrial Targeting.

Triphenylphosphine functionalized carbon dots (TPP-CDs) showcase robust mitochondria targeting capacity owing to their positive electrical properties. However, TPP-CDs typically involve complicated synthesis steps and time-consuming postmodification procedures. Especially, the one-step target-oriented synthesis of TPP-CDs and the regulation of TPP linkage modes remain challenges.

Changes in the indicators of stiffness and remodeling of magistral arteries in young patients at the early stage of essential hypertension under conditions of syntropy with obesity.

Objective: Aim: The study and analysis of indicators of remodeling and rigidity of magistral vessels in young essential hypertension patients with abdominal obesity and determination of the detected changes as a possible criterion for their remodeling..

Patients And Methods: Materials and Methods: 98 young people with essential hypertension and obesity were included in the study.

Rapamycin functionalized carbon Dots: Target-oriented synthesis and suppression of vascular cell senescence.

Suppression of vascular cell senescence is of great significance in preventing cardiovascular diseases such as hypertension and atherosclerosis. The oxidative stress damage caused by reactive oxygen species (ROS) can lead to cellular senescence. Rapamycin (Rapa) is well known to suppress cell senescence via mammalian target of rapamycin (mTOR) pathway.
