A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

Advanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Synthesis of Nitroxide-Annulated Carbocycles and Heterocycles [PDF]

, 2012
New, pyrroline nitroxide annulated lactones, polycycles, and maleimide were synthesized by classical and microwave-assisted methodology. We report the application of the metathesis reaction in the presence of nitroxide yielding a pyrroline nitroxide ...

Wafer‐Scale 2D High‐Entropy Transition Metal Dichalcogenide Thin‐Film Catalysts for Efficient and Durable Photoelectrochemical Hydrogen Production

Advanced Materials, EarlyView.
A wafer‐scale 2D high‐entropy (MoWTaNbRu)S2 thin‐film catalyst with a distorted 1T phase integrated onto p‐Si photocathode is designed for highly efficient and durable photoelectrochemical hydrogen evolution reaction. The high‐entropy effect in layered transition metal dichalcogenides optimizes hydrogen adsorption energetics, accelerates photogenerated

Naturally occurring epoxy acids: i. detection and evaluation of epoxy fatty acids by paper, thin-layer, and gas-liquid chromatography*†

Journal of Lipid Research, 1961
Chromatographic procedures for the detection and evaluation of oxygenated fatty acids are described. Emphasis has been placed on epoxy acids, but these methods promise to be of great value in studies of all classes of oxygenated acids.

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

Advanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical
