Analysis of structural defects and their influence on red-emitting γ-AlO:Mn,Mg nanowires using positron annihilation spectroscopy.

The present paper reported on the analysis of structural defects and their influence on the red-emitting γ-AlO:Mn,Mg nanowires using positron annihilation spectroscopy (PAS). The nanowires were synthesized by hydrothermal method and low-temperature post-treatment using glucose as a reducing agent. X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL), and photoluminescence excitation (PLE) were utilized, respectively, for determining the structural phase, morphology and red-emitting intensity in studied samples.

Promoted Hydrogen Peroxide Production from Pure Water on g-CN with Nitrogen Defects Constructed through Solvent-Precursor Interactions: Exploring a Complex Story in Piezo-Photocatalysis.

Hydrogen peroxide (HO) production via oxygen (O) reduction reaction (ORR) in pure water (HO) through graphitic carbon nitrides (g-CN)-based piezo-photocatalysts is an exciting approach in many current studies. However, the low Lewis-acid properties of g-CN limited the catalytic performance because of the low O adsorption efficacy. To overcome this challenge, the interaction of g-CN precursors with various solvents are utilized to synthesize g-CN, possessing multiple nitrogen-vacant species via thermal shocking polymerization.

Review on personal protective equipment: Emerging concerns in micro(nano)plastic pollution and strategies for addressing environmental challenges.

The COVID-19 pandemic was caused by the SARS-CoV-2 virus, marking one of the most catastrophic global health crises of the 21st century. Throughout this period, widespread use and improper disposal of personal protective equipment (PPE) emerged as a pressing environmental issue, significantly impacting various life forms. During the COVID-19 pandemic, there was a high rate of PEP disposal.

and docking and molecular dynamic of antimicrobial activities, alpha-glucosidase, and anti-inflammatory activity of compounds from the aerial parts of .

Twelve compounds were isolated from aerial parts through phytochemical analysis and the genus is the first place where the compounds 4-6 and 11-12 have been found. Based on the ability to inhibit NO production in RAW264.7 cells, compound 2 has demonstrated the strongest anti-inflammatory activity with an IC of 7.
