Reverse Weak Polarity‐Induced Ordered Layer Control for Enhanced Second‐Harmonic Generation in Ultraviolet Nonlinear Optical Crystals

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Reverse Weak Polarity‐Induced Ordered Layer Control strategy, optimizing the design of layered structures, has been successfully designed. By leveraging inhomogeneous field of units to replace isotropic fields of metal cations, polar layers realize controllable layer stacking via a “layer→linker→layer” polarity transfer.

Goniothalamin as a Styryl‐Lactone Toxicophore in Cancer Models: Electrophile‐Driven DNA Damage, Reactive Oxygen Species–Endoplasmic Reticulum Stress Signaling and Detoxification‐Relevant Safety Considerations

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Goniothalamin (GTN) exerts anticancer effects by promoting reactive oxygen species (ROS) generation, glutathione (GSH) depletion, DNA damage, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. These interconnected events trigger apoptosis, necroptosis, anoikis, and autophagy, while modulating mitogen‐activated protein kinase (MAPK ...

Metabolic Regulation of Macrophages in Health and Disease

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Extracellular metabolites drive metabolic rewiring of glucose, lipid, and amino acid pathways in macrophages, steering their polarization toward pro‐ or anti‐inflammatory phenotypes and shaping a wide range of disease processes. Macrophages from different tissues display distinct metabolic signatures, and therapeutic strategies that target these ...

Curing Behavior and Structure Reactivity‐Property Relationships in Epoxidized Linseed Oil Thermosets Crosslinked With Biobased Eutectic Hardeners

open access: yesJournal of Polymer Science, Volume 64, Issue 15, Page 3275-3288, 1 August 2026.
The curing of epoxidized linseed oil with citric, tartaric, and malic acid–based eutectic hardeners is compared to reveal how acid functionality, hydroxyl content, and molecular geometry govern activation energy, reaction rates, and network rigidity.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Most of the Specific Genomic Regions of Agrobacterium fabrum Shape Phenolics Content of Medicago truncatula Roots

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Agrobacterium fabrum harbour seven specific‐gene regions, whose annotation indicates a close connection with plant. To evaluate their involvement in plant‐bacteria interaction, deletion mutant strains of each specific region were inoculated onto Medicago truncatula roots. Root phenolics content was influenced by them.

Pyridine C─N Transposition via Cycloaddition–Cycloreversion

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Transposition of pyridine nitrogen from the 4‐ to the 3‐position is described using two open and shut sequences: a nucleophile addition ring‐open ring‐closure, followed by a nitrile Diels–Alder cycloaddition cycloreversion. The nitrogen swap is particularly effective for tertiary alkyl substituents, transforming easily accessible para‐alkylated ...

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...
