Effect of structure and interaction on physicochemical properties of new [Emim][BFX] complex anion ionic liquids studied by quantum chemistry.

Context: One of the key challenges in the industrial application of ionic liquids (ILs) is their extreme characteristics, such as viscosity, glass transition temperatures, and conductivity. Understanding the relationship between ILs structure and physicochemical property is a crucial aspect of the directed design of ILs with good properties, which is a prerequisite for their successful implementation in industrial processes. In this work, high-level quantum-chemical research with for four pairs ionic liquids, [Emim][X] and [Emim][BFX] (X = CHSO, EtSO, HSO, Tos), was performed, to analyze the stable structure, interionic interaction, and charge transfer and provide a new insight into the property variances at the molecular level.

Stereoselective synthetic approach toward β-trifluoromethyl vinyl ethers and diethers reaction of ()-1,2-dichloro-3,3,3-trifluoroprop-1-ene with phenols.

A convenient method for synthesizing β-trifluoromethyl vinyl ethers and diethers through the base-mediated C-O coupling of ()-1,2-dichloro-3,3,3-trifluoroprop-1-ene and phenols has been developed. Remarkably, the present process shows perfect regioselective and stereoselective yield of the / isomers for β-trifluoromethyl vinyl ethers with high efficiency. Additionally, β-trifluoromethyl vinyl diethers with identical/diverse phenoxy groups were also obtained and the regulation of the product configuration was achieved.

Study on the photoaging process and metal ion release of plastic films with two kinds of structures in marine environment: Aliphatic and aromatic polymers.

The prevalence of plastics in the oceans has significantly intensified microplastic pollution, contributing to broader marine secondary pollution issues. This paper examines how plastic structure affects the aging characteristics of plastics and the release of metal ions, to better understand this secondary source of marine pollution. This study simulate the photoaging of plastics in natural environments, focusing on aliphatic and aromatic polymers.

The cocktail probe drug method was used to investigate the effects of diabetic nephropathy (DN) and HQD on metabolic enzyme activity.

Investigation on Depression of College Students Majoring in Physical Education and Nonphysical Education: A StudyBased on the Age Region and Gender of 374 Students.

In the research on the relationship between depression and college students' major, there are some differences in the degree of depression between sports major and nonsports major students. Based on these results, we assume that there is the possibility of emotional differences between professional and nonprofessional sports. A total of 374 samples of students majoring in physical education and nonphysical education at the same university were analyzed by using the methods of literature review and data analysis.

Release of the additive metals from 3 commonly used plastics during the degradation under the treatment of UV irradiation.

Additive metals are continuously released into the environment during the photo-degradation of plastics into microplastics, but this phenomenon has not been reported by many studies. Herein, we investigated the surface morphology changes along with the release of additive metals (Cr, Mn, Fe, Co, Cu, Zn, and Pb) during the degradation of three types of plastics, i.e.

Room temperature monitoring of SFdecomposition byproduct SOFbased on TiO/NiSOcomposite nanofibers.

Sulfuryl fluoride (SOF) is one of the ideal decomposition components of sulfur hexafluoride (SF), which is widely used as an insulating and arc extinguishing medium in gas-insulated switchgear. To detect the decomposition component of SFat room temperature, the use of SOFis still a challenge. In this work, we have successfully fabricated TiOnanofibers and nickel sulfate (NiSONPs) via simple electrospun and hydrothermal methods, followed by calcination process to improve the sensing performance.

New Insights into CO Adsorption on Layered Double Hydroxide (LDH)-Based Nanomaterials.

The interlamellar spacing of layered double hydroxides (LDHs) was enlarged by dodecyl sulfonate ions firstly, and then, (3-aminopropyl)triethoxysilane (APS) was chemically grafted (APS/LDHs). The structural characteristics and thermal stability of these prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), reflectance Fourier transform infrared spectrometer (FTIR), thermogravimetric analysis (TG), and elemental analysis (EA) respectively.
