Ambient-condition acetylene hydrogenation to ethylene (AC-AHE) is a promising process for ethylene production with minimal additional energy input, yet remains a great challenge due to the difficulty in the coactivation of acetylene and H at room temperature. Herein, we report a highly efficient AC-AHE process over robust sulfur-confined atomic Pd species on tungsten sulfide surface. The catalyst exhibits over 99% acetylene conversion with a high ethylene selectivity of 70% at 25 C, and a record space-time yield of ethylene of 1123 mol mol h under ambient conditions, which is nearly four times that of the typical PdAg/AlO catalyst, and exhibiting superior stability of over 500 h.

In this context, glucose oxidase (GOx), by catalyzing glucose to produce gluconic acid and hydrogen peroxide, not only modulates the hyperglycemic microenvironment but also possesses antibacterial and oxygen-supplying functions, thereby demonstrating immense potential in the treatment of diabetic wounds. Despite the growing interest in GOx-based therapeutic strategies in recent years, a systematic summary and review of these efforts have been lacking.

The advent of high-throughput omics technologies, such as genomics, transcriptomics, proteomics, and epigenomics, has revolutionized the molecular understanding of AD. Conventional AI approaches typically require the completion of all omics data at the outset to achieve optimal AD diagnosis, which are inefficient and may be unnecessary.

However, robust protocols are essential to ensuring single-cell sequencing data quality and cell viability. Here, we present a protocol for acquiring high-quality single-cell multi-omics data from human peripheral blood mononuclear cells (PBMCs).

However, where and how PI3K-AKT signaling is spatially activated and organized in mammalian cells remains poorly understood. Here, we identify focal adhesions (FAs) as subcellular signaling hubs organizing the activation of PI3K-PI(3,4,5)P-AKT signaling in human cancer cells containing p110α mutations under basal conditions.

Investigation on seizure detection based on deep learning models has achieved great success. However, there still remain challenging issues, such as the high computational complexity of the models and overfitting caused by the scarce availability of ictal electroencephalogram (EEG) signals for training.

These hydrolysis-stable ether intermediates exhibit reactivity toward electron-donating groups and nucleophiles in cross-coupling and nucleophilic substitution reactions while surpassing the stability of corresponding aryl halides. In comparison to conventional coupling methods, this protocol offers an alternative pathway for accessing natural product and drug-like compounds without the need for metal catalysts.

Previous studies have demonstrated that nitazoxanide (NTZ), an antiparasitic gastroenteritis medication classified as a thiazolide, exhibits efficacy against JEV both in vitro and in vivo. To explore the potential antiviral mechanisms, we employed Tandem Mass Tag (TMT)-based quantitative proteomics to identify differentially expressed proteins (DEPs) among three groups: Blank cell group, JEV-infected cell group, and JEV-infected cells treated with NTZ.

By incorporating the C into TiC, a nanocomposite film with abundant three-dimensional porousness is coated on the TFBG surface. The nanocomposite film with strong hygroscopicity and desorption properties is highly sensitive to environmental humidity variations, where the induced refractive index changes of the coating result in the spectral responses of TFBG multi-resonances.

Herein, g-CN quantum dot decorated amorphous hollow CoFe bimetallic phosphate nanocubes (a-CoFePO@CNQD) are prepared as an efficient OER electrocatalyst by a simple etching-phosphating process. Research shows that their unique hollow architecture and amorphous structure can help provide generous exposed active sites for OER, and the incorporation of g-CN quantum dots can effectively adjust the electronic structure to improve the intrinsic activity.

Surface modification of metallic nanocatalysts with organic ligands has emerged as an effective strategy to enhance catalytic selectivity, although often at the expense of catalytic activity. In this study, we demonstrate a compelling approach by surface modifying PdS nanocrystals with PPh ligands, resulting in a catalyst with excellent catalytic activity and durable selectivity for the semi-hydrogenation of terminal alkynes. Experimental and theoretical investigations reveal that the presence of S sites on the Pd surface directs PPh ligands to preferentially form covalent bonds with S, creating distinctive surface S=PPh motifs.

The self-heating lunch box (SHLB) is a kind of popular instant food in China, yet little is known about the associated chemical release risk during its heating process. In this study, we investigated organophosphate esters (OPEs) in original unheated food (UF), SHLB-heated processed food (HF) and potential OPE release from SHLB packaging materials. Significantly higher concentrations of OPEs were observed in HF (267 ± 246 ng/g dry weight (dw)) than in UF (163 ± 211 ng/g dw) ( < 0.
