Improved Mechanistic Modeling on Reproducing Particle-Bound Mercury in the Marine Atmosphere.

Mercury (Hg) is a neurotoxic pollutant that is ubiquitous on the planet and receives global concern because of its adverse health effects. Particle-bound Hg formation in the atmosphere stems mainly from the adsorption of reactive gaseous Hg on aerosol particles, particularly sea salt aerosol. However, the observed comparable abundance of Hg over Hg in the marine atmosphere has not been reproduced by traditional statistics-based schemes, which were constructed by continental observations.

Zinc Chloride-Doped g-CN Microtubes for Enhanced Photocatalytic Degradation of Tetracycline Hydrochloride.

Morphology regulation and element doping are effective means to improving the photocatalytic performance of graphite-phase carbon nitride (g-CN). In this article, using melamine and zinc chloride as raw materials, a novel kind of Zn/Cl-doped hollow microtubular g-CN (Zn-HT-CN) by a hydrothermal method was developed. The structure and morphology of Zn-HT-CN and reference samples were characterized by X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), etc.

Thermoelectric Properties of a Light Compound FeS: the Role of Electron Correlation Strengthened Spin-Orbital Coupling.

Spin-orbit coupling (SOC) induced nontrivial bandgap and complex Fermi surface has been considered to be profitable for thermoelectrics, which, however, is generally appreciable only in heavy elements, thereby detrimental to practical application. In this study, the SOC-driven extraordinary thermoelectric performance in a light 2D material Fe₂S₂ is demonstrated via first-principles calculations. The abnormally strong SOC, induced by electron correlation through 3d orbitals polarization, significantly renormalizes the band structures, which opens the bandgap via Fe 3d orbitals inversion, exposes the second conduction valley with weak electron-phonon coupling, and aligns the energy of Fe 3d and S 3p orbitals with divergent momentum in valence band.

A comparative evaluation of rehabilitation approaches for ecological recovery in arid limestone mine sites.

Limestone mining in arid regions, particularly within fragile environments, leads to severe environmental pollution and ecological degradation. Developing a scientifically sound and effective ecological rehabilitation strategy is therefore critical. This study constructed a three-dimensional ecological rehabilitation model integrating soil amelioration and vegetation reconstruction.

The relationship between self-efficacy, learning burnout, willingness to fulfill the contract and empathy of rural-oriented tuition-waived medical students of China: a cross-sectional study.

Background: The empathy of rural-oriented tuition-waived medical students (RTMSs) is closely related to the construction of good doctor-patient relationship and the quality of rural medical and health services. The purpose of this study is not only to explore the relationship between self-efficacy, learning burnout, willingness to fulfill the contract and empathy, but also to explore the mediating role of self-efficacy between learning burnout and empathy, and between willingness to fulfill the contract and empathy.

Methods: Four hundred ninety-five rural-oriented tuition-waived medical students from 3 medical universities in Shandong Province were selected as research subjects, and General self-efficacy scale (GSES), Learning burnout of university student (LBUS), Willingness to fulfill the contract scale and Jefferson Scale of Physician Empathy-student version (JSPE-S) were used to investigate.
