A Generalized Approach for Distal C–H Arylation of Organic Building Blocks: Unveiling the Role of Counter Anion

open access: yesAdvanced Science, EarlyView.
We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.

Enzyme‐Inspired Hydrogen‐Bonded Organic Frameworks for Synergistic Capture, Detection, and Degradation of Nerve Agent Simulants

open access: yesAdvanced Science, EarlyView.
FDU‐HOF‐5, an enzyme‐inspired hydrogen‐bonded framework, enables targeted capture, real‐time visual alert, and detoxification of nerve agent simulants through biomimetic sites and multivalent interactions. Integrable into protective gear, it pioneers on‐site threat monitoring strategies for persistent neurotoxic hazards, advancing smart, responsive ...

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

open access: yesAdvanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...

Molecular Weaving of Mixed‐Addenda Polyoxometalates into MOF Nanochannels as Electron‐Buffering Reservoirs for Enhanced Nitrate‐to‐Ammonia Electrocatalysis

open access: yesAdvanced Science, EarlyView.
Synergistic interaction between P2W17V1 and FeMOF owing to its efficient proton/electron transfer affording high yield and Faradaic efficiency in electrocatalytic nitrate reduction to ammonia. ABSTRACT Electrochemical conversion of nitrate pollutants into value‐added ammonia (e‐NO3RA) offers a sustainable pathway for nitrogen valorization, yet hinges ...

A TtAgo‐Driven Autocatalytic Circuit with Thermal‐Enhanced Kinetics for One‐Pot Nucleic Acid Detection

open access: yesAdvanced Science, EarlyView.
This study proposes a universal catalytic DNA circuits termed TACTIC (Thermus thermophilus protein‐driven autocatalytic circuit) for one‐pot detection of DNA and RNA in multiple clinical samples. Integrated with machine learning, TACTIC accurately profile the distinct expression of four extracellular vesicle‐derived miRNAs across different samples and ...
