Establishment of Gas-Liquid-Solid Interface on Multilevel Porous CuO for Potential-Driven Selective CO Electroreduction toward C or C Products.

Copper-based catalysts demonstrate distinctive multicarbon product activity in the CO electroreduction reaction (CORR); however, their low selectivity presents significant challenges for practical applications. Herein, we have developed a multilevel porous spherical CuO structure, wherein the mesopores are enriched with catalytic active sites and effectively stabilize Cu, while the macropores facilitate the formation of a "gas-liquid-solid" three-phase interface, thereby creating a microenvironment with an increasing water concentration gradient from the interior to the exterior. Potential-driven phase engineering and protonation synergistically optimize the reaction pathway, facilitating a switch between CO and CH.

Chemosensory Cues Modulate Women's Jealousy Responses to Vocal Femininity.

In-situ isomerization and reversible self-assembly of photoresponsive polymeric colloidal molecules enabled by ON and OFF light control.

Photocatalytic colloids enable light-triggered nonequilibrium interactions and are emerging as key components for the self-assembly of colloidal molecules (CMs) out of equilibrium. However, the material choices have largely been limited to inorganic substances and the potential for reconfiguring structures through dynamic light control remains underexplored, despite light being a convenient handle for tuning nonequilibrium interactions. Here, we introduce photoresponsive N,O-containing covalent organic polymer (NOCOP) colloids, which display multi-wavelength triggered fluorescence and switchable diffusiophoretic interactions with the addition of triethanolamine.

Mg-Doped Cu Catalyst for Electroreduction of CO to Multicarbon Products: Lewis Acid Sites Simultaneously Promote *CO Adsorption and Water Dissociation.

The electroreduction of CO to valuable fuels or high-value chemicals by using sustainable electric energy provides a promising strategy for solving environmental problems dominated by the greenhouse effect. Copper-based materials are the only catalysts that can convert CO into multicarbon products, but they are plagued by high potential, low selectivity, and poor stability. The key factors to optimize the conversion of CO into multicarbon products are to improve the adsorption capacity of intermediates on the catalyst surface, accelerate the hydrogenation step, and improve the C-C coupling efficiency.

Long-Chain Molecular Crystals Antimony(III) Alkanethiolates Sb(SCH) ( ≥ 12): Synthesis, Crystal and Electronic Structures, and Supramolecular Self-Assembly via Secondary Interactions.

Currently, there is not much success in solving the molecular and crystal structures of long-chain metal alkanethiolate complexes [M(SCH)] at the atomic level. Taking Sb(SCH) () as an example, we herein disclose the structural characteristics of long-chain trivalent antimony(III) alkanethiolates Sb(SCH) ( ≥ 12) by single-crystal X-ray crystallography. Specifically, the Sb atom is three-coordinated by alkanethiolate ligands and a slightly distorted triangular pyramid SbS core is formed owing to the unique intramolecular stereochemistry of three alkyl chains, namely, two of them almost parallel aligning and the third chain extending alone around the SbS core.

Enhancing local K adsorption by high-density cube corners for efficient electroreduction of CO to C products.

Reducing carbon dioxide (CO) to high value-added chemicals using renewable electricity is a promising approach to reducing CO levels in the air and mitigating the greenhouse effect, which depends on high-efficiency electrocatalysts. Copper-based catalysts can be used for electroreduction of CO to produce C products with high added value, but suffer from poor stability and low selectivity. Herein, we propose a strategy to enhance the field effect by varying the cubic corner density on the surface of CuO microspheres for improving the electrocatalytic performance of CO reduction to C products.

Release of a ubiquitin brake activates OsCERK1-triggered immunity in rice.

Plant pattern-recognition receptors perceive microorganism-associated molecular patterns to activate immune signalling. Activation of the pattern-recognition receptor kinase CERK1 is essential for immunity, but tight inhibition of receptor kinases in the absence of pathogen is crucial to prevent autoimmunity. Here we find that the U-box ubiquitin E3 ligase OsCIE1 acts as a molecular brake to inhibit OsCERK1 in rice.
