Neem oil (Azadirachta indica) as a promising feedstock for biolubricant production: enzymatic synthesis, process optimization, and molecular studies

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 237-252, January/February 2026.
Abstract The fuel industry remains closely tied to oil‐based fuels. This relationship is responsible for increasing greenhouse gas emissions. Biofuels are an alternative to petroleum‐based fuels that could make industrial production lines more sustainable.

Synthesis, Characterization, and Enhanced Antibacterial Properties of Nanocomposites Based on Cu, Ag, and Au Nanoparticles Supported on the Coordination Polymer [Zn2(1,3‐bdc)(Bzim)2]

ChemistrySelect, Volume 10, Issue 47, December 15, 2025.
Nanocomposites based on Cu, Ag, or Au nanoparticles supported on the coordination polymer [Zn2(1,3‐bdc)(Bzim)2] were successfully synthesized, maintaining high structural stability. These materials demonstrated significantly superior antibacterial activity, reaching up to 16 times the efficacy of amoxicillin.

When Barchan Dunes Move Over Craters

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We investigate the possible outcomes of a subaqueous barchan moving over a crater‐like depression in the bed. For that, we carried out experiments where we varied the dune size, crater and grain diameters, and flow velocities. We found that subaqueous barchans can be blocked, destroyed, or pass over craters, with transitional situations, and ...
