Covalent organic framework (COF) is a promising material for oxygen catalysis. Herein, a novel highly stable conjugated two-dimensional Poly (benzimidazole porphyrin-cobalt) (PBIPorCo) with a large delocalization energy is synthesized by…
With the rapid increase in temperatures around the planet, the need to develop efficient means to reduce CO2 emissions has become one of the greatest challenges of the scientific community.…
Overcoming spin-forbidden radiation in chiral phosphors has attracted enormous attention because of their capacity in circularly polarized organic ultra-long room temperature phosphorescence (CP-OURTP). However, their developments have been hindered by…
Completely or partially ordered intermetallic compounds possess unique electronic structures and chemical bonding endowing them as an emergent class of catalytic materials for selective hydrogenation reactions. In this review, we…
This study explores a novel N-heterocyclic carbene-mediated siloxane exchange mechanism, laying the foundation for designing covalent adaptable networks (CANs) with high temperature stability (>200 °C) for the dynamic covalent chem-istry.…
Single-atomic Cu catalysts show promise for electrochemical CO2 reduction (CO2RR) to acetate, but their efficiency is limited by the difficulty in generating the CO intermediate needed for C–C coupling. While…
The justices heard arguments in a constitutional challenge to a task force that decides what treatments are covered at no cost. Source link
In-brief analysis April 21, 2025 In 2024, pipeline companies completed five pipeline projects to transport petroleum liquids in the United States, according to our recently…
This study presents a generic method to selectively enhance radiative pathways over non-radiative states by leveraging vibrational coupling between the host lattice and mid-gap states of doped transition metal ions.…
Ullmann coupling has been one of the most important organic reactions for the formation of aryl–aryl bond, which is of great significance in medicinal chemistry, natural product synthesis, and optoelectronic…
