Electrostatic‐Attraction‐Driven Self‐Assembled Graphene‐Disordered Rocksalt Composite Cathode for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A non‐aqueous, solution‐based graphene‐wrapping strategy is shown to stabilize disordered rocksalt LMTOF cathodes without structural degradation. The graphene‐wrapped cathode suppresses oxygen loss and parasitic interfacial reactions, lowers impedance growth, and delivers improved cycling stability and rate capability compared with conventional ball ...

Preparation and surface active properties of oxypropylated diol monoesters of fatty acids with an amide oxime terminal group

Grasas y Aceites, 1994
Locally produced non-edible oil, namely, rice bran oil (R.B.O.) was utilized as starting materials for preparing new nonionic surfactant. Oxypropylated diol monoesters of linoleic and rice bran oil fatty acids were prepared.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

Advanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...
