In this work, advanced polymer nanocomposites comprising of polyvinyl alcohol (PVA) and nanodiamonds (NDs) were developed using a single-step solution-casting method. The properties of the prepared PVA/NDs nanocomposites were investigated using Raman spectroscopy, small- and wide-angle X-ray scattering (SAXS/WAXS), scanning electron microscopy (SEM), (TEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA). It was revealed that the tensile strength improved dramatically with increasing ND content in the PVA matrix, suggesting a strong interaction between the NDs and the PVA. SEM, TEM, and SAXS showed that NDs were present in the form of agglomerates with an average size of ~60 nm with primary particles of diameter ~5 nm. These results showed that NDs could act as a good nanofiller for PVA in terms of improving its stability and mechanical properties.

A CoO/AgMoO/CeOternary nanocomposites photocatalyst was successfully synthesized through a straightforward ethanol-assisted chemical method. Comprehensive characterization of its structural and optical properties was conducted using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. XRD analysis confirmed the presence of CoO, AgMoO and CeO in the ternary composite sample.

Cachexia, the loss of skeletal muscle mass and function with cancer, contributes to reduced life quality and worsened survival. Skeletal muscle fibrosis leads to disproportionate muscle weakness; however, the role of infiltrating immune cells and fibro-adipogenic progenitors (FAPs) in cancer-induced muscle fibrosis is not well understood. Using the C26 model of cancer cachexia, we sought to examine the changes to skeletal muscle immune cells and FAPs which contribute to excessive extracellular matrix (ECM) collagen deposition.

Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can form when nuclear detonations, asteroids, and comets produce near-surface or "touch-down" airbursts. When cosmic airbursts detonate with enough energy and at sufficiently low altitude, the resultant relatively small, high-velocity fragments may strike Earth's surface with high enough pressures to generate thermal and mechanical shock that can fracture quartz grains and introduce molten silica into the fractures.

This study presents the development of multifunctional starch-based biopolymer films reinforced with nitrogen-doped carbon quantum dots (N-CQDs), synthesized via a hydrothermal method, and exhibiting a high quantum yield (~70 %). N-CQDs were incorporated into the starch matrix at varying concentrations (0.1-1.

In recent years, the hydrazide skeleton, as a pivotal class of nitrogen-containing structures, has garnered considerable attention in medicinal chemistry and organic synthesis owing to its unique chemical versatility and broad-spectrum biological activities. In this study, a series of thiazole-containing benzoylhydrazine derivatives -, -, and - with structural divergence from conventional hydrazide-based molecular frameworks were designed, synthesized, and evaluated for their antifungal/antioomycete activities. The antifungal/antioomycete assay showed that some of the targeted compounds exhibited remarkable and broad-spectrum antifungal activities.
