Agricultural Waste Valorization of Sugarcane Bagasse Ash for Low-Carbon Concrete Applications

This study demonstrates that incorporating 10% sugarcane bagasse ash as a cement replacement optimizes the balance between workability, setting time, and environmental sustainability by reducing CO₂ emissions by 8–10% while enhancing the concrete matrix through pozzolanic reactions, despite increased water demand and extended setting times at higher replacement levels.

Model Ag/HOPG catalysis for ethylene epoxidation: comparison of methods for the preparation of large Ag particles with high surface coverage

This study identifies thermal vacuum deposition on freshly peeled HOPG as the superior method for preparing uniform, high-coverage Ag model catalysts suitable for ethylene epoxidation mechanistic studies, while demonstrating that Ar+ etching damages the graphite surface and renders samples unsuitable for such research.

Comparative Investigation of Efficacy of Non-toxic and Conventional Solvents for Separation of Gallic acid

This study evaluates the extraction efficiency of gallic acid using both conventional toxic solvents (toluene and cyclohexane) and non-toxic natural oils (soyabean and mustard oil), finding that while conventional solvents yield higher extraction rates, the environmentally benign natural oils offer a viable alternative for industrial-scale recovery through reactive extraction.

Chemical composition and hygroscopicity of thermally modified Eucalyptus grandis wood in closed and open systems

This study demonstrates that thermal modification of juvenile *Eucalyptus grandis* wood in both closed and open systems significantly alters its chemical composition and reduces hygroscopicity, with the open system at higher temperatures (190–210°C) proving most effective for minimizing moisture absorption despite requiring higher thermal energy.

A DFT Investigation of Tautomeric Equilibria in 4-Acetamido- and 4-Amino-2-hydroxyquinolines

This DFT study explains why 4-acetamido-7-methyl-2-hydroxyquinoline exists exclusively as the hydroxy tautomer while its amino analog forms a mixture, attributing the difference to a combination of a higher kinetic barrier for tautomerization, the specific orientation of the acetamido group, and the stabilization of the hydroxy form by acetic acid through dual hydrogen bonding.

Silica fume as an industrial by-product modifier for reducing quicklime demand in earthen building materials: mechanical, microstructural and carbon-performance assessment

This study demonstrates that incorporating silica fume as a partial substitute for quicklime in earthen building materials enhances compressive strength and microstructural compactness while reducing carbon emissions, with an optimal replacement range of 1.5–3.1 parts per 100 parts of dry materials (approximately 4.8%–9.8% of the binder fraction) identified to balance mechanical performance and environmental benefits.
