Summary: In this study, the interfacial region between a borosilicate glass coating and Ti-6Al-4V alloy at high temperature was accurately described using a combination of Raman and Backscatter Electron Diffraction imaging. This interface consists of five different phases, including Ti2O3, TiB2, TiB, Ti5Si3, and Ti6Si2B, which provide protection against oxygen permeation. Additionally, a Raman database for Ti borides, silicides, and borosilicides was developed using experimental and theoretical (DFT computations) data.

Summary: The first evidence of the chrome yellow dyeing method was found on late 19th-century Karen textiles from Myanmar. Non-invasive observations using digital microscopy and fibre optic reflectance spectroscopy suggested the presence of non-conventional organic colorants in yellow, orange, and green threads. Further analyses using scanning electron microscopy and micro-Raman spectroscopy confirmed the identification and characterization of PbxCrOy formulations precipitated onto cotton fibres. The study also revealed a unique dyeing scenario where European-imported cotton threads were over-dyed locally by Karen people to achieve desired color shades.

Summary: This study aimed to synthesize and evaluate dentin adhesive polymer with and without silica nanoparticles. SEM, EDX, mu TBS test, FTIR, and micro-Raman spectroscopy were used to investigate the shape and incorporation of Si particles, dentin bond toughness, DC, and adhesive-dentin interaction. The addition of 15% and 10% Si particles showed improved bond strength in dentin adhesive, with the highest strength observed in the 15% group. The Si-EA-15% group demonstrated acceptable DC, suitable dentin interaction, and resin tag formation.

Summary: Microwave was used to facilitate the synthesis of pure and tungsten-doped lead iodide nanosheets with thickness less than 100 nm. The synthesized nanosheets were characterized structurally, morphologically, spectrally, optically, dielectrically, and radiationally. SEM and EDX investigations confirmed the influence of tungsten dopants on the undoped PbI2 matrix. XRD patterns showed good crystallinity of the prepared W-doped PbI2 nanostructures. Optical characterizations revealed the energy band structure. The dielectric constant varied with W doping concentrations, indicating an increasing dielectric trend. The prepared W-doped PbI2 nanostructured sheets showed potential applications in radiation detectors.

Summary: Roughness, pigment impurities, and neoformed minerals are important factors affecting the reflectance of painted surfaces. Other factors such as the total thickness of the paint layer and the amount of binder should also be considered. The distribution of pigments and binder in the paint system, as well as their interaction, are key to understanding reflectance values.

Summary: Biodegradable plastic mulches (BDMs) have the potential to be an eco-friendly alternative to conventional plastic mulches in agriculture. However, their long-term impacts on soil ecosystems are still uncertain, and further research is needed. Incorporating BDMs into the soil may stimulate microbial activity, but there is also a risk of incomplete degradation and release of residual microplastics and additives.
