Electrochemical reduction of CO is an important way to achieve carbon neutrality, and much effort has been devoted to the design of active sites. Apart from elevating the intrinsic activity, expanding the functionality of active sites may also boost catalytic performance. Here we designed "negatively charged Ag (nc-Ag)" active sites featuring both the intrinsic activity and the capability of regulating microenvironment, through modifying Ag nanoparticles with atomically dispersed Sn species. Different from conventional active sites (which only mediate the surface processes by bonding with the intermediates), the nc-Ag sites could also manipulate environmental species. Therefore, the sites could not only activate CO, but also regulate interfacial HO and CO, as confirmed by operando spectroscopies. The catalyst delivers a high current density with a CO faradaic efficiency of 97 %. Our work here opens up new opportunities for the design of multifunctional electrocatalytic active sites.

The widely used Radix Astragali (RA) has significant therapeutic effects on cognitive impairment (CI) caused by type 2 diabetes (T2DM). However, the effective active ingredients and the precise mechanism underly RA alleviation of T2DM-induced CI still require further study. In this study, we aim to elucidate whether and how jaranol, a key effective active ingredient in RA, influences CI in db/db mice.

Problematic internet use and unsafe internet use are the two main potential negative consequences of children's online activities. Parents play a vital role in mitigating these consequences and creating a safe digital environment. Parental Vigilant Care (PVC) is a systematic approach that integrates active and restrictive mediation practices, allowing parents to regulate their involvement according to the alarm signs they detect.

Single-atom catalysts (SACs) have become the forefront and hotspot in energy storage and conversion research, inheriting the advantages of both homogeneous and heterogeneous catalysts. In particular, carbon-supported SACs (CS-SACs) are excellent candidates for many energy storage and conversion applications, due to their maximum atomic efficiency, unique electronic and coordination structures, and beneficial synergistic effects between active catalytic sites and carbon substrates. In this review, we briefly review the atomic-level regulation strategies for optimizing CS-SACs for energy storage and conversion, including coordination structure control, nonmetallic elemental doping, axial coordination design, and polymetallic active site construction.

As primary air pollutants from fossil fuel combustion, the excess emission of nitric oxides (NO) results in a series of atmospheric environmental issues. Although the selective catalytic reduction technology has been confirmed to be effective for NO removal, green purification and value-added conversion of NO under ambient conditions are still facing great challenges, especially for nitrogen resource recovery. To address that, photo-/electrocatalysis technology offers sustainable routes for efficient NO purification and upcycling under ambient temperature and pressure, which has received considerable attention from scientific communities.

The mechanism and activity of the water-gas shift reaction (WGSR) on single-atom alloy Al/Cu (111) and Cu (111) surfaces were studied using GGA-PBE-D3. Al/Cu (111) exhibited bifunctional active sites, with the Al site being positively charged and the Cu site negatively charged due to electronic interactions. This led to selective adsorption of HO and CO.
