Article Abstract
Determination of the lattice dynamics of Sn at high pressure has represented a major experimental challenge and eluded previous attempts. Here we report the first successful measurement of the phonon density of states of Sn at high pressure to 64 GPa using nuclear resonant inelastic x-ray scattering. We also present density functional theory calculations that are in excellent agreement with the measured data. The results of this combined experimental and theoretical study establish reliable phonon density of states of Sn at high pressure. It makes possible an accurate description of its thermodynamic properties that are of great importance and interest in high pressure research.
Fast-charging lithium-ion batteries (LIBs) are the key to solving the range anxiety of electric vehicles. However, the lack of separators with high Li transportation rates has become a major bottleneck, restricting their development. In this work, the electrochemical performance of traditional polyethylene separators was enhanced by coating AlO nanoparticles with a novel green binder.
Micellar liquid chromatography (MLC) has proven beneficial efficiency and ecological impact for routine quality control activities. In the proposed study, cyrene was investigated for the first time, together with other green additives, as a novel safe organic solvent in reversed-phase MLC. Quality-by-design (QbD) approach screened their effect on the separation performance.
Aims: The purpose of this study was to investigate the prevalence of sexual harassment among operating room nurses, and to analyze the influencing factors.
Background: Sexual harassment in the healthcare field has a high incidence and nurses are the main victims; sexual harassment not only leads to physical and mental problems, but also undermines nurses' performance and affects the quality of medical care.
Methods: A multi-center cross-sectional study was conducted using an online survey to investigate the sexual harassment experiences of 483 operating room nurses.

Background: Terpenes have been shown to have an effect on metabolic status. However, it is unclear how they are associated with the metabolic syndrome (MetS) and whether insulin resistance (IR) mechanisms are involved.
Methods: This cross-sectional study included data from the National Health and Nutrition Examination Survey (2013-2014).
This study utilized deep learning to optimize antihypertensive peptides from whey protein hydrolysate. Using the Large Language Models (LLMs), we identified an optimal multienzyme combination (MC5) with an ACE inhibition rate of 89.08% at a concentration of 1 mg/mL, significantly higher than single-enzyme hydrolysis.
