Siloxane‐Activated Through‐Space Conjugation in Conventional Chromophores for Dual‐State Emission

Aggregate, Volume 7, Issue 5, May 2026.
Siloxane‐activated through‐space conjugation (TSC) in polymer chains creates dual‐state emissive materials. Through a “dynamic encapsulation” mechanism, siloxane linkages organize chromophores into non‐covalently coupled assemblies, yielding high quantum yields.

Probing Electronic Effects Upon Nucleophilicity and Lewis Basicity of Isothiourea HyperBTM Catalyst Derivatives

ChemistryEurope, Volume 4, Issue 5, May 2026.
Systematic variation of the position and electronic effect of substituents within the benzannulated aromatic part of the HyperBTM catalyst framework indicates that catalysts containing electron‐donating substituents outperform their electron‐deficient variants in terms of rate and enantioselectivity in acylation reactions.

Toward Tailored Metastability: Exploring Oxanorbornene Chemical Space for Structure–Stability Relationships With Atypical Furan Diels–Alder Adducts

ChemistryEurope, Volume 4, Issue 5, May 2026.
The furan Diels–Alder reaction is a versatile platform for metastable and biobased molecules and materials. By accessing atypical oxanorbornene adducts, we expand furan Diels–Alder chemistry beyond activated addends and show that cycloreversion stability can be tuned over six orders of magnitude, revealing structure–stability relationships that enable ...

Correspondence of Basal Forebrain Resting‐State Functional Connectivity and Cerebral Glucose Metabolism Alterations With Neurotransmitter Maps in Alzheimer's Disease

CNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
Altered functional connectivity of basal forebrain subregions (Ch1‐3, Ch4) and widespread cerebral hypometabolism were identified in Alzheimer's disease using simultaneous PET/MRI. Spatial correspondence with normative neurotransmitter receptor and transporter maps suggested that serotonergic and dopaminergic systems may contribute to AD‐related ...

Climate and Land‐Use Change May Reshape the Biogeography of Freshwater Crabs Across China

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict
