Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

Macromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

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.

Hot deformation and dynamic recrystallization in Al-Mg-Si alloy

Materials Characterization, 2021
The hot deformation behavior of Al-Mg-Si alloys was investigated by isothermal compression tests in a temperature range from 400 °C to 550 °C and a strain rate range from 0.001 to 1 s−1 with a true strain of 1.2.
