Mechanochemically Driven Synthesis of Anticancer Cocrystals: A Case Study of Lenalidomide

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
The combination of crystal engineering and mechanochemical approaches is a powerful strategy for the rational screen and development of new solid forms of active pharmaceutical ingredients (API). New supramolecular patterns formed between an API and a coformer allow the adjustment of physicochemical properties of drugs.

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 13, 1 May 2026.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Degradation of pigments in Limnospira platensis extracts

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4426-4438, May 2026.
Abstract BACKGROUND Limnospira platensis, commonly known as spirulina, holds promise for application as a food ingredient and nutraceutical due to its rich protein and antioxidant content, including chlorophylls, carotenoids and phycocyanin. Despite its potential, the vibrant colour poses a challenge for consumer acceptance, hampering the marketability

Connected reservoirs: Modeling aquatic ecosystems along a cascade system in Brazil

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Connected reservoirs along cascade systems have been constructed along large rivers worldwide, establishing a network of aquatic environments that greatly affect matter flux and ecological dynamics. Here, we explore the underlying ecological principles of their unidirectional connectivity, applying a modeling framework that explicitly links ...

Structural Insights Into CO2 Transport Pathways in a W‐Formate Dehydrogenase: Structural Basis for CO2 Reduction

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.
