Biodiesel Production From Canola Oil by Titanium Dioxide‐Photocatalysed Transesterification

GCB Bioenergy, Volume 18, Issue 6, June 2026.
Photocatalytic transesterification of canola oil over TiO2 under UVA irradiation enables biodiesel production under mild conditions. Yields up to 73% FAME and 38% FAEE were achieved, with negative Gibbs free energy (ΔG < 0) confirming thermodynamic favourability.

Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...
