Al@FPIL preparation of composite fuel and its inhibition mechanism of aluminum agglomeration in solid propellants

四川大学学报. 自然科学版
Aluminum （Al） powder is a key component of composite solid propellants that provides high specific impulse. However， Al tends to agglomerate during the combustion process， leading to reduced combustion efficiency.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...

MOF‐Derived Superaerophobic Ni‐CoOOH Nanosheet Anchored on Stretched Carbon via In Situ Morphology Reconstruction for Durable Oxygen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study constructed an in situ superhydrophobic OER catalyst with excellent activity and durability. Ni‐Co expansion induced tensile strain, converting the polyhedral framework into vertical nanosheets that enhance intrinsic activity and bubble detachment.
