Charting Morphotoxicity With Complementary Embryo Models

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.
Three human embryo models of the peri‐implantation stages are exposed to a library of compounds. The (toxic) effects of the compounds are analyzed through automated image analysis pipelines. By evaluating the differential responses of the embryo models, this study underscores the importance of testing complementary embryo models to achieve robust and ...

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 5, Page 2096-2105, September/October 2026.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Combining Phytochemical and Computational Approach on Citrus hystrix DC. (Kaffir Lime) Peel Extract: Anti‐Diabetic and Anti‐Inflammatory Activities

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Citrus hystrix DC. (kaffir lime) peel was dried and subjected to ethanolic extract. The GC‐MS analysis showed the presence of significant phyto‐ingredients. Pharmacokinetic and ADMET filters were applied to major constituents, and molecular docking, Gene Ontology (GO), and KEGG pathway enrichment analyses on mechanistic plausibility were also performed.

Solvent Extraction of Chromium by Salicylic, Thiosalicylic, and Phthalic Acids [PDF]

open access: yes, 1977
The use of salicylic, thiosalicycle, and phthalic acids as chelating agents for the extraction of Cr(III) from aqueous solution was investigated. Normal butanol was selected as a solvent due to its relatively low solubility in the aqueous phase.
