We present a mild and direct method for the radical borylation of simple aliphatic aldehydes. By employing an enamine and a photocatalyst under light irradiation, aldehydes can be transformed effectively into alkyl boronic esters via a formal decarbonylative process. This alternative route for radical borylation synthesis can not only be applied to the transformation of primary, secondary, and tertiary aldehydes but also be adapted to other radical conversion reactions through the generated alkyl radical intermediate.

Electrochemical nitroarene reduction enables the green production of anilines at ambient conditions thanks to the manipulated transfer of multiple electrons and protons via controlling potentials and currents, but challenges remain in pH-neutral electrolysis using nonprecious catalysts. Here, Chevrel phase MoS with high conductivity and insertable frameworks is proposed for the first time as a cost-efficient candidate with prominent performance and, more importantly, as a new platform to unravel cation effects on nitroarene electroreduction. Nanosized MoS derived from polymer-confined sulfidation affords a high yield (∼95%) and Faradaic efficiency (∼99%) for reducing 4-nitrostyrene to 4-aminostyrene at -0.

Silica-based aerogels are widely regarded as promising sound-absorbing materials due to their low density and high specific surface area. However, their hard surface and small pores hinder sound wave penetration, resulting in a relatively poor sound absorption performance. To overcome this limitation, our study employs melamine foam (MF) as a scaffold to construct a gradient aerogel composite acoustic absorber.

Superwetting surfaces have attracted considerable attention in analytical fields due to their unique ability to concentrate target analytes within evaporating droplets, characterized by a constant contact angle and a centripetal mobile contact line. While previous studies have underscored the resistance of superslippery surfaces to the coffee-ring effect, our research presents a novel strategy that dynamically introduces the coffee-ring effect on such surfaces for visual detection. By harnessing the synergistic interaction between the coffee-ring effect and the mobile contact line properties of the superslippery surface, our work leverages affinity recognition between the functionalized surface and the target analyte within the droplet to dynamically create defects for contact line pinning, thereby generating coffee rings on the superslippery surface and enabling qualitative visual detection based on their distinct patterns.

Zirconium metal-organic cages (Zr-MOCs) that assemble from zirconocence-based clusters and carboxylate-based ligands have been widely used as building blocks for constructing various MOC-based materials with diverse applications because of their high stability and solubilities. However, in this work, we found that the structures of a series of Zr-MOCs are quite flexible when heated at 60 °C in an ,'-dimethylformamide solution, in which they are completely disassembled into fragments and reassembled into amorphous metal-organic gels (MOGs). The transformation mechanism was investigated via proton nuclear magnetic resonance, electrospray ionization mass spectrometry, infrared spectroscopy, X-ray photoelectron spectroscopy, and other techniques, which revealed that cyclopentadiene (CP) breaks out of the [ZrCP(μ-OH)(μ-O)] cluster and remains in solution, whereas the trinuclear [Zr(μ-OH)(μ-O)] cluster dimerizes into a hexanuclear [Zr(μ-OH)(μ-O)] cluster and forms amorphous MOGs with terephthalic acid-based ligands.

A target-triggered, enzymatic cascade-amplified low-field nuclear magnetic resonance (LF-NMR) sensor was developed for the detection of the circulating tumor cell (CTC) A549. A multifunctional two-dimensional bionanomaterial GDA@GOX&DNA1 was designed as the initiator, with FeO@DNA2/Apt as the recognition unit and CaO@MnO as the signal unit. When A549 was present, the aptamer (Apt) detached from the recognition unit, allowing the formation of GDA@GOX&DNA1-DNA2@FeO and triggering the following reactions: (1) glucose oxidase (GOX) catalyzed the reaction between the substrate glucose and oxygen (O) to produce gluconic acid and hydrogen peroxide (HO); (2) the generated acid and HO reacted with MnO, producing signal probes Mn and O; and (3) CaO reacted with the acid, generating HO.

Understanding genetic regulation of metabolism is critical for gaining insights into the causes of metabolic diseases. Traditional metabolome-based genome-wide association studies (mGWAS) focus on static associations between single nucleotide polymorphisms (SNPs) and metabolite levels, overlooking the changing relationships caused by genotypes within the metabolic network. Notably, some metabolites exhibit changes in correlation patterns with other metabolites under certain physiological conditions while maintaining their overall abundance level.

Mixed halide wide-bandgap (WBG) perovskites, widely used as a top-cell absorber in tandem solar cells, exhibit severe photoinduced halide phase segregation. A feasible solution is to exploit pure-iodide WBG perovskites, essentially increasing Cs content instead of Br to achieve bandgap widening. However, the efficiency of pure-iodine WBG perovskite solar cells (PSCs) reported so far has been inferior to that of the typical mixed halide WBG PSCs due to complex nucleation and phase transition processes, leading to poor crystallization quality and a high density of defect states in pure-iodine WBG perovskites.
