Highly stable benzonitrile functionalized covalent organic framework coating for solid-phase microextraction of hydroxyphenyl esters in complex matrix samples.

A mesoporous surface benzonitrile functionalized covalent organic framework (TpBD-CN-COF) was synthesized as a novel solid-phase microextraction (SPME) fiber coating for the extraction of six hydroxyphenyl esters (PBs), and combined with gas chromatography-flame electric-ion detector (GC-FID). PBs were sensitively determined in aqueous solution. Due to its high specific surface area, high chemical stability in both strongly acidic and alkaline media, and in polar or non-polar media, as well as its high thermal stability, the TpBD-CN-COF fiber coating showed excellent extraction performances for PBs with an enrichment factor twice as high as that of TpBD-COF.

Photoelectrochemical Solution Gated Graphene Field-Effect Transistor Functionalized by Enzymatic Cascade Reaction for Organophosphate Detection.

Solution Gated Graphene Field-Effect Transistors (SGGT) are eagerly anticipated as an amplification platform for fabricating advanced ultra-sensitive sensors, allowing significant modulation of the drain current with minimal gate voltage. However, few studies have focused on light-matter interplay gating control for SGGT. Herein, this challenge is addressed by creating an innovative photoelectrochemical solution-gated graphene field-effect transistor (PEC-SGGT) functionalized with enzyme cascade reactions (ECR) for Organophosphorus (OPs) detection.

Spinel Nanostructures for the Hydrogenation of CO to Methanol and Hydrocarbon Chemicals.

Composite oxides have been widely applied in the hydrogenation of CO/CO to methanol or as the component of bifunctional oxide-zeolite for the synthesis of hydrocarbon chemicals. However, it is still challenging to disentangle the stepwise formation mechanism of CHOH at working conditions and selectively convert CO to hydrocarbon chemicals with narrow distribution. Here, we investigate the reaction network of the hydrogenation of CO to methanol over a series of spinel oxides (ABO), among which the Zn-based nanostructures offer superior performance in methanol synthesis.

In Situ Synthetic ZIF-8/Carbon Aerogel Composites as Solid-Phase Microextraction Coating for the Detection of Phthalic Acid Esters in Water Samples.

In this study, a hybrid composite featuring zeolitic imidazolate framework-8/carbon aerogel (ZIF-8/CA) was synthesized via in situ nucleation and growth of ZIF-8 nanoparticles inside carbon aerogels. The novel material was used as the solid-phase microextraction (SPME) coating for the five phthalic acid esters (PAEs) detection by coupling with a gas chromatography-flame ionization detector (GC-FID). Compared with bare carbon aerogel, the ZIF-8/CA presented the best performance, which is attributed to the unique advantages between the high surface area of CA and high hydrophobic properties, the thermal stability of ZIF-8, and their synergistic adsorption effects, such as molecular penetration, hydrogen bond, and π-π stacking interactions.

Vacancy engineering of two-dimensional WN nanosheets for efficient CO hydrogenation.

Peaking carbon emissions and achieving carbon neutrality have become the consensus goal of the international community to solve the environmental problems threatening mankind caused by accumulative greenhouse gases like CO. Herein we proposed vacancy engineering of two-dimensional (2D) topological WN for efficient CO hydrogenation into high value-added chemicals and fuels. Spherical aberration corrected scanning transmission electron microscopy (Cs-corrected STEM) confirmed a large amount of N vacancies on the catalyst surface, which significantly reduced the energy barrier for the formation of the essential intermediates of *CO and *CHO as revealed by density functional theory (DFT) calculations.

HMGB1-Mediated Neutrophil Extracellular Trap Formation Exacerbates Intestinal Ischemia/Reperfusion-Induced Acute Lung Injury.

Influx of activated neutrophils into the lungs is the histopathologic hallmark of acute lung injury (ALI) after intestinal ischemia/reperfusion (I/R). Neutrophils can release DNA and granular proteins to form cytotoxic neutrophil extracellular traps (NETs), which promotes bystander tissue injury. However, whether NETs are responsible for the remote ALI after intestinal I/R and the mechanisms underlying the dissemination of harmful gut-derived mediators to the lungs are unknown.
