Article Abstract
Preparation of irreversible sp carbon-conjugated covalent organic frameworks (spc-COFs) with specific porosity, easy structural functionalization, high chemical stability, and unique π-electron conjugation structure (especially the combination of π-π stacking interactions and conjugation system), can remove the barrier of electron transfer and provide a unique advantage for photocatalytic water splitting. Herein, based on three kinds of reactions (Aldol condensation reaction, Knoevenagel condensation reaction, and Horner-Wadsworth-Emmons reaction) and guided by the precise modulation of ligand structure and topology, this review summarizes the synthesis of spc-COFs and their applications in photoelectrocatalytic water splitting (hydrogen evolution and oxygen evolution reactions). Furthermore, challenges and possible research directions for spc-COFs in photocatalytic water splitting are also provided.

Liquid crystal monomers (LCMs) have emerged as novel endocrine disrupting chemicals that affect the growth, development, and metabolism of organisms by binding to nuclear hormone receptors (NHRs). However, the studies on the impact of LCMs' molecular features on their binding affinities remain limited. In this study, considering the challenge of activity cliffs in linear quantitative structure-activity relationship modeling, a multidimensional feature fusion model was developed to predict the binding affinities of 1173 LCMs to 15 NHRs.

Developing highly active and stable nonprecious electrocatalysts toward sluggish alkaline oxygen evolution reaction (OER) is essential for large-scale green hydrogen production via electrochemical water splitting. Here we report phase and surface co-reconstruction of S-doped (NiCo)WC nanoparticles into (NiCo)C with amorphous electroactive NiCoOOH layer for highly efficient alkaline OER by W dissolution and NiCo surface oxidation. The W dissolution results in the formation of Brønsted base WO ions, which electrostatically accumulate around electrode to promote water dissociation into abundant OH* intermediates, in situ constructing a locally strong alkaline microenvironment to facilitate OH* adsorption on NiCoOOH sites and trigger lattice-oxygen oxidation path.

Background: Cold-stored platelets (CSP) are now being used to treat acute bleeding. However, as CSP are less suitable for prophylaxis, both room temperature (RT) platelets and CSP will be required, which complicates inventory management. The production of CSP "on-demand" from RT platelets may be a desirable option.

Constructing robust electrocatalysts and shedding light on the processes of surface reconstruction is crucial for sustained hydrogen production and a deeper understanding of catalytic behavior. Here, a novel ZIF-67-derived lanthanum- and phosphorus-co-doped CoO catalyst (La, P-CoO) has been reported. X-ray absorption spectroscopy (XAS) confirms that the La and P co-doping reduces the coordination number (CN), improves oxygen vacancies (O), and leads to lattice distortion.
