Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Small, EarlyView.A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.

Effects of geometry on brush seal pressure and flow fields - Part II: Backing plate configurations
, 2006 Brush seal dynamic behavior is strongly related to pressure and flow fields. Developments in brush seal design have led to geometric modifications to control flow field and consequent brush seal issues including blow-down, hang-up, and pressure ...

Recyclable Printed Liquid Metal Composite for Underwater Stretchable Electronics
Small Science, Volume 5, Issue 5, May 2025.This work presents a multifunctional liquid metal (LM) microdroplet‐based composite with a custom‐designed block copolymer as the matrix, optimized for printing. The composite exhibits high conductivity, stretchability, durability in dry and aqueous environments, and recyclability of LM using green solvents. These properties highlight its potential for

A new tribological test for candidate brush seal materials evaluation
, 1994 A new tribological test for candidate brush seal materials evaluation has been developed. The sliding contact between the brush seal wires and their mating counterface journal is simulated by testing a small tuft of wire against the outside diameter of a
