Pd-zeolites are promising passive NO adsorber (PNA) materials for mitigating cold-start emissions from lean-burn engines. However, their practical deployment is constrained by insufficient densities and dispersion of isolated Pd active sites as well as their susceptibility to hydrothermal degradation and phosphorus poisoning encountered in vehicle exhaust environments. Herein, we develop a rationally engineered core-shell Pd/SSZ-13@AlO composite, featuring a Pd/SSZ-13 core encapsulated within a mesoporous AlO shell.

Molecular switches-compounds capable of reversibly interconverting between distinct states in response to external stimuli-are foundational to the design of dynamic functional materials. Classical switches based on carbon and lighter pnictogen frameworks, such as stilbenes, azobenzenes, and imines, have long dominated the field owing to their well-defined photophysical properties, synthetic accessibility, and reversible /-isomerization or related transformations. In recent years, significant efforts have been devoted to designing molecular switches incorporating main-group elements-not only to harness the unique attributes of these elements in expanding the frontier of stimuli beyond light and heat, but also to unlock novel mechanistic pathways.

Enantioselective desymmetrization of prochiral phosphorus(V) compounds represents a pivotal strategy for constructing P(V)-stereogenic skeletons, yet existing methods face limitations in structural diversification and metal-free catalytic systems. Here we disclose that a bioinspired peptide-phosphonium salt (PPS) catalytic system successfully enables precise desymmetrization of phosphinic acids through synergistic ion-pairing and hydrogen-bonding interactions. This strategy affords multifunctional platform molecules bearing P(V)-stereocenters with excellent enantiocontrol and broad compatibility (43 examples, up to 92% yield, up to >99% ee) at very low catalyst loading (1 mol%).

Methane and phosphorus recovery from waste activated sludge (WAS) sustainably addresses environmental and energy challenges facing wastewater treatment. This study investigated an ethylenediaminetetraacetic acid (EDTA) pretreatment strategy (0-20 mmol/L) to enhance dual resource recovery. EDTA chelates cations, disrupting extracellular polymeric substances and membranes to release organics, enriching acid-fermenting bacteria for short-chain fatty acid (SFCA) production and hydrogen-utilizing, methane-generating methanogens.

The anaerobic/aerobic/anoxic (AOA) process has demonstrated exceptional efficacy in nitrogen removal from municipal wastewater, achieving effluent nitrogen concentrations below 2.0 mg/L subverts the dilemma of traditional nitrogen removal process. As the cornerstone nitrogen elimination pathway in AOA process, intracellular carbon sources driven denitrification necessitates comprehensive characterization and systematic analysis to unlock its full engineering potential.
