Pd-Based Multi-Site Catalysts for Selective CO-to-Methanol Conversion.

Developing a multi-site Pd-based electrocatalyst for CO-to-C1 conversion with high performance and selectivity in the hydrogenation pathway for the CO electroreduction reaction is both desirable and challenging. Here, we develop triple-site metallene (PdBiIn), which can achieve an unprecedented Faraday efficiency of 72.6 ± 1% for methanol production.

Exosomes in Action: Unraveling Their Role in Autoimmune Diseases and Exploring Potential Therapeutic Applications.

Exosomes are double phospholipid membrane vesicles that are synthesized and secreted by a variety of cells, including T cells, B cells, dendritic cells, immune cells, are extracellular vesicles. Recent studies have revealed that exosomes can play a significant role in under both physiological and pathological conditions. They have been implicated in regulation of inflammatory responses, immune response, angiogenesis, tissue repair, and antioxidant activities, particularly in modulating immunity in autoimmune diseases (AIDs).

Efficient Electrochemical Nitrate Removal by Ordered Ultrasmall Intermetallic AuCu via Enhancing Nitrate Adsorption.

Developing a high-performance electrocatalyst for synthesizing ammonia from nitrate represents a promising solution for addressing wastewater pollution and achieving sustainable ammonia production. However, it remains a formidable challenge. Herein, an intermetallic AuCu electrocatalyst with high-density active sites is designed and prepared for an efficient nitrate electroreduction to generate ammonia.

A probability prediction method for the classification of surrounding rock quality of tunnels with incomplete data using Bayesian networks.

The classification of surrounding rock quality is critical for the dynamic construction and design of tunnels. However, obtaining complete parameters for predicting the surrounding rock grades is always challenging in complex tunnel geological environment. In this study, a new method based on Bayesian networks is proposed to predict the probability for the classification of surrounding rock quality of tunnel with incomplete data.

The pathophysiological mechanisms underlying diabetic retinopathy.

Diabetic retinopathy (DR) is the most common complication of diabetes mellitus (DM), which can lead to visual impairment and even blindness in severe cases. DR is generally considered to be a microvascular disease but its pathogenesis is still unclear. A large body of evidence shows that the development of DR is not determined by a single factor but rather by multiple related mechanisms that lead to different degrees of retinal damage in DR patients.
