Computational Screening Guiding the Development of a Covalent-Organic Framework-Based Gas Sensor for Early Detection of Lithium-Ion Battery Electrolyte Leakage.

This study presents a computationally guided approach for selecting covalent organic frameworks (COFs) for the selective detection of the trace ethylene carbonate (EC) vapor, a key indicator of electrolyte leakage from lithium-ion batteries (LIBs). High-throughput screening, employing grand canonical Monte Carlo (GCMC) simulation complemented by density functional theory (DFT) calculations, was used to identify potential COF candidates from the CURATED COF database. Among the screened materials, an imine COF functionalized with quaternary ammonium (QA) groups, named COF-QA-4, exhibited a high adsorption capacity (5.

Magnetic molecularly imprinted polymers coupled with UPLC-MS/MS for simultaneous detection of 19 steroid hormones in human plasma.

Steroid hormones constitute a group of hormones with molecular weights ranging from 200 to 400 daltons, characterized by their highly similar chemical structures. Each hormone within this group holds significant value for the diagnosis of various diseases. Accurate clinical measurement of the levels of each hormone is crucial for the diagnosis in clinical settings.

Commonly Neglected Ester Groups Enhanced Microwave Absorption.

Oxygen-containing functional groups have high potential to excite polarization loss. The nature and mechanism of the polarization loss brought on by oxygen-containing functional groups, however, remain unclear. In this study, metal-organic framework precursors are in situ pyrolyzed to produce ultrathin carbon nanosheets (UCS) that are abundant in oxygen functional groups.

Toxicity of Nanoscale Zero-Valent Iron to Soil Microorganisms and Related Defense Mechanisms: A Review.

Soil pollution is a global environmental problem. Nanoscale zero-valent iron (nZVI) as a kind of emerging remedial material is used for contaminated soil, which can quickly and effectively degrade and remove pollutants such as organic halides, nitrates and heavy metals in soil, respectively. However, nZVI and its composites can enter the soil environment in the application process, affect the physical and chemical properties of the soil, be absorbed by microorganisms and affect the growth and metabolism of microorganisms, thus affecting the ecological environment of the entire soil.

Adsorption of Heavy Metal Ions Copper, Cadmium and Nickel by .

To investigate the treatment effect of algae biosorbent on heavy metal wastewater, in this paper, the adsorption effect of powder on heavy metal ions copper, cadmium and nickel was investigated using the uniform experimental method, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and TG-DSC comprehensive thermal analysis. The experimental results showed that the initial concentration of copper ion solution was 25 mg/L, the temperature was 30 °C, the pH value was 8 and the adsorption time was 5 h, which was the best condition for the removal of copper ions by algae powder adsorption, and the removal rate was 83.24%.

Novel Cellulose Nanocrystals-Based Polyurethane: Synthesis, Characterization and Antibacterial Activity.

As a new type of polymer, water-driven polyurethane (PU) has attracted increasing attention of researchers; however, with the popularization of its application, the following infection problems limit their applications, especially in the biomedical field. Herein, a series of novel cellulose nanocrystals (CNCs)-based PUs were first synthesized by chemical cross-linking CNCs with triblock copolymer polylactide-poly (ethylene glycol)-polylactide (CNC-PU). After covalent binding with tannic acid (TA-CNC-PU), the silver nanoparticles (Ag NPs) were further introduced into the material by a reduction reaction (Ag/TA-CNC-PU).

Are the measurement structures of the Traditional Chinese Dispositional Flow Scale-2 equivalent between schizophrenic patients and healthy subjects?

Background: The Dispositional Flow Scale-2 (DFS-2) is an instrument for measuring the flow experiences of the general population while participating in daily activities. This study aimed to examine the equivalence in the measurement structure of Traditional Chinese DFS-2 (TCDFS-2) between the schizophrenic patients and healthy subjects.

Methods: We recruited 100 adults with schizophrenia or schizoaffective disorder from the psychiatric clinics or the centers for daycare or rehabilitation and 104 healthy adults.

Traditional-Chinese Dispositional Flow Scale-2 and Flow State Scale-2 in Taiwanese subjects with schizophrenia or schizoaffective disorder.

Introduction: The 36-item Dispositional Flow Scale-2 (DFS-2) and Flow State Scale-2 (FSS-2) were developed to assess flow experience in daily and specific activities. Although their validity and reliability had been examined in general populations and different cultures, little is known for schizophrenic subjects. Thus, this study aimed to validate Traditional-Chinese DFS-2 (TCDFS-2) and FSS-2 (TCFSS-2) in Taiwanese subjects with schizophrenia or schizoaffective disorder.
