The conversion of nitrate (NO3−) contaminants into ammonia (NH3) through electrochemical reduction presents a viable strategy for the dual purposes of wastewater purification and ammonia production. Meanwhile, dealing with hazardous heavy metals (Cu, Ni, etc.) in the electroplating industry is a global mandate, incurring substantial cost and consuming vast energy. This work integrates the treatment

Ba7Nb4MoO20 is a hexagonal perovskite derivative that exhibits both high oxide-ion and proton conductivity. The high oxide-ion conductivity results from the presence of disordered flexible MOx (x = 3, 4, 5) units within the palmierite-like layer. The high proton conductivity arises from the dynamic and rotational flexibility of the MOx units that results in delocalisation of the proton defects, high

Highly stable para-sulfonated calix[4]arene (SCA), a bowl-shaped macrocycle possessing intrinsic porosity, was incorporated in the spherical voids of the micro-mesoporous MIL-101(Cr) metal-organic framework by adsorptive loading from a solution. The pore-space partitioning in the MOF by polar functionalized macrocyclic molecules, which can also act as hosts, led to the host@MOF composite SCA@MIL-101

Molecular doping of n-type polymers creates Coulombically bound charge carriers or counterion pairs via a charge-transfer process. Synergistic optimization of the miscibility and free charge carriers release within a specific polymer:n-dopant pair poses a formidable challenge for high-performance n-type organic thermoelectrics. In this work, the density of free charge carriers and the thermoelectric

Covalent organic frameworks (COFs) with ordered channels and light weight are regarded as promising separator modifications for lithium-sulfur (Li-S) batteries. However, they typically suffer from stability issues and limited electrocatalytic activity, resulting in unsatisfactory battery performance. Herein, a donor-acceptor (D-A) COF (BTT-DABD) featuring oxazole linkages is developed through a one-step
