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 ...

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1948-1969, November/December 2025.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Effect of Solution Temperature on the Microstructure of 18%Ni Maraging Steel Modified With Nb—X‐Ray Diffraction and Electron Backscattered Scanning Diffraction (EBSD) Analyzes

X-Ray Spectrometry, Volume 54, Issue 5, Page 547-555, September/October 2025.
ABSTRACT Maraging steels are high strength alloys used in applications that require both high mechanical strength and toughness. To achieve these properties, one of the heat treatments applied is solution treatment, although it can reduce toughness.
