Direct air capture (DAC) suffers from challenges related to co-adsorption of water during CO₂ capture. This work reports a self-supporting hydrophobic solid amine polymer exhibiting a CO₂ uptake of 5.2...
For rare targets in complex samples, ultrasensitive biosensing requires not only strong signal amplification but also reliable discrimination of target-derived signals from background. Confinement-enabled nanobiosensing addresses this challenge by organizing...
The metal-sulfurization strategy steers 4e⁻ O2 reduction pathway of a porous electrocatalyst. Integrated with a well-developed quasi-solid-state electrolyte, and a FeNiOOH/FeN-BiVO4 photoanode, this self-powered portable photoelectrochemical (PEC) cell generates electricity...

Hydroxycarboxylic acid receptor 1 (HCAR1) is a Gi/o-coupled GPCR implicated in cancer metabolism and immune evasion, yet its ligand discovery is hindered by a scarcity of validated inhibitors. We report...
α-Deutero acyloins and C-1 deuterated aromatic aldehydes are synthesized via NHC catalysed umpolung using D2O under mechanochemical conditions. The competing aldehyde deuteration and deutero-benzoin condensation are controlled by the steric...

Well-defined active sites and tunable electronic features of single-atom catalysts (SACs) enable great versatility in modulating their electrocatalytic activity. However, an understanding of how the electronic structure governs the catalytic...
We present an aptamer-gated exonuclease signal amplification (AGESA) strategy decoupling target recognition from DNAzyme activation to overcome background limitations, enabling selective detection of platelet-derived growth factor BB in urine and unlocking the DNAzyme repertoire for protein biomarkers.
This work explores degradation of Li-rich Mn-based layered oxide cathodes using an operando FBG-DEMS platform for simultaneous strain and gas detection. Variable-temperature tests further verify lattice mechanical destabilization precedes oxygen...
Halide-incorporated MnCo2O4.5 reconstructs the Co-centred interfacial water network for acidic oxygen evolution. Compared with pristine and F-regulated MnCo2O4.5, Cl-MnCo2O4.5 couples a moderately distorted Co environment with an intermediate-H-bond-enriched water network, enabling efficient and durable non-noble-metal acidic OER.
V3O4-modified CoFe nitrides nanoarray enables durable oxygen evolution for alkaline water and seawater electrolysis through vanadium-mediated electronic reconstruction, dynamic oxyvanadate protection, and hydrogen-bond network regulation, providing an effective interfacial engineering...
Vinyl sulfoxonium ylides are traditionally confined to two-electron cyclization chemistry, limiting their utility in intermolecular C-C bond formation. Herein, we demonstrate that reductive activation of vinyl sulfoxonium ylides under Zn/TiCl₄...
2,4-Dienyl sulfones are highly significant moieties in organic synthesis. While the conventional methods for their synthesis rely on the ‘leaving-group’ strategy to introduce the sulfonyl group and hence reducing the...
A dinuclear iron(II) complex supported by a bidentate amide ligand is used as a surrogate to study potential intermediates for C-H oxidation mediated by iron on silica. Both oxygen and...
Metal–organic frameworks (MOFs) have emerged as a versatile class of porous crystalline materials owing to their exceptionally high surface area, tunable pore architectures, and modular chemical functionality. Despite these advantages,...

NiFe layered double hydroxides (LDHs) modified with a tripodal ligand combine high oxygen evolution reaction (OER) activity with rapid self-repairing capability via colloidal electrochemical deposition. Size reduction of LDHs markedly accelerates deposition, enabling stable performance over 1000 start/stop cycles. These findings advance self-repairing OER catalysts for durable alkaline water electrolysis.
A one-pot protocol combining Pd-catalyzed defluorinative amination and TfOH‑promoted Nazarov cyclization enables diastereoselective synthesis of α‑fluorinated naphthocyclopentanones from α,α‑difluoro ketones and secondary amines. The mild tandem reaction tolerates diverse substrates, giving products in up to 90% yield and >20 : 1 dr for most cases.
