Solvothermal Fabrication of Trimetallic Oxides NCs: Exploring Their Magnetic and Photocatalytic Characteristics

Nano Select, Volume 7, Issue 4, April 2026.
A trimetallic NiFe2O4/ZnO/Co3O4 nanocomposite is synthesized via a solvothermal route and thermally tuned by post‐annealing. Structural, optical, and magnetic properties evolve systematically with temperature, enabling efficient sunlight‐driven degradation of mixed organic dyes.

Tunable Structural Color in Copolymer Microgels Through Controlled Synthesis and Thermally Induced Assembly

Small Science, Volume 6, Issue 4, April 2026.
Poly(N‐isopropylacrylamide) (PNIPAm)‐based copolymer microgels with incorporated anionic, cationic, and neutral comonomers served as multifunctional colloidal building blocks for the formation of dynamic structural colors. Precise control over synthesis parameters and self‐assembly behavior allow for the fine‐tuning of the reflected color across the ...

Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications

Environmental Toxicology, Volume 41, Issue 4, Page 223-232, April 2026.
ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the
