Bright Self‐Trapped Exciton Emission of CsPbBr3@CsPb2Br5 Nanostructures Created by Dissolution and Recrystallization of Hydrophilic Cu:CsPbBr3

Small, EarlyView.
This work reports a differentiated ion‐doping strategy to engineer the self‐trapped exciton emission of CsPbBr3@CsPb2Br5 nanostructures, in which bright orange emission is obtained by the dissolution and recrystallization of Cu:CsPbBr3 in water. Lattice‐incorporated Cu components create self‐trapped exciton centers because of bright green emission ...

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

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.

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

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

steel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

The Avrami kinetics of dynamic recrystallization

Acta Materialia, 2009
Twenty-six flow curves determined under dynamic recrystallization (DRX) conditions on 11 different steels were analyzed. The double-differentiation method was used to define the critical strain ec for initiation of DRX. The “athermal” hardening parameter h and the dynamic recovery parameter r were evaluated from the work-hardening behavior prior to ec.

Development of dynamic recrystallization theory

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2004
Although hot working had been defined as deformation above the recrystallization temperature (determined after cold working), it was only about 1965 that dynamic recrystallization (DRX) was confirmed to be occurring during the deformation; two decades were required to clarify the similarities to, and the differences from, static recrystallization.
