Ultrafine Ru‐M Alloy@S Vacancy‐Rich MoS2 Nanosheets With Bimetallic Active Sites for Efficient Hydrogen Evolution in Alkaline and Acidic Media

open access: yesAdvanced Science, EarlyView.
A USMR synthesizes ultrafine RuCo alloy on S‐vacancy‐rich 1T phase MoS2. This method enables rapid precursor mixing, instantaneous reduction, and uniform alloy dispersion while creating S vacancies. The synergy between Ru‐Co sites and defective MoS2 optimizes hydrogen kinetics, achieving a low overpotential of 31 mV@10 mA·cm‐2 in acid, providing a ...

From Solution to Surface: How the Catalytic Environment Modulates Peptide Bond Cleavage by Metal‐Oxo Cluster Nanozymes

open access: yesAdvanced Science, EarlyView.
Comparison of homogeneous Hf12(sol) and heterogeneous Hf12(precip) metal‐oxo clusters enables investigation of how solubility influences nanozymatic reactivity and selectivity toward proteolysis, without introducing confounding factors from differences in cluster identity.

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.

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 ...
