Universal In Situ Isotope Exchange Raman Spectroscopy (IERS) Methodology for Measuring Oxygen Surface Exchange Dynamics Using a Probe Layer

open access: yesAdvanced Functional Materials, EarlyView.
A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Modeling static recrystallization during non-isothermal heating in biomedical Mg-1Zn-0.2Ca magnesium alloy based on isothermal kinetic data

open access: yesResults in Engineering
A novel analytical model is proposed to predict the kinetics of static recrystallization (SRX) during non-isothermal annealing, based on isothermal experimental data.

The Effect of Stepped Austempering on Phase Composition and Mechanical Properties of Nanostructured X37CrMoV5-1 Steel

open access: yesArchives of Metallurgy and Materials, 2015
This paper presents the results of studies of X37CrMoV5-1 steel subjected to quenching processes with a one-step and a two-step isothermal annealing. The TEM observation revealed that steel after one-step treatment led is composed of carbide-free bainite

Stabilizing Cationic Palladium Single‐Atom Sites on Heteroatom‐Doped Carbon for Selective Hydrogen Peroxide Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
In this research, it is demonstrated that dual nitrogen and sulfur doping in hollow carbon spheres creates a tunable coordination environment that stabilizes cationic Pd single atoms as robust organometallic complexes, enabling high selectivity and stability for electrochemical hydrogen peroxide production under harsh acidic and peroxide‐rich ...

Isothermal annealing influence on structural defects and some characteristics of Bismuth Telluride wire crystals

open access: yesMoldavian Journal of the Physical Sciences, 2007
Possibilities to control microdefect formation in bismuth telluride wire crystals by choice of optimal modes of isothermal annealing are discussed. It is found that a decrease of density of structural defects, such as microcracks, dislocations, and ...

Isothermal annealing of hillocks in AlCu films

open access: yesThin Solid Films, 1989
Abstract Vapor deposited Al-15 wt.% Cu films were formed on oxidized silicon substrates at room temperature. Subsequent heating of these samples resulted in the formation of copper-rich hillocks on the surface of the films because of compressive, substrate-induced differential thermal expansion strains.

The Evolution of Microstructure and Mechanical Properties of Al-Mn-Fe-Si Alloys During Isothermal Annealing

open access: yes, 2015
Recrystallization during isothermal annealing is studied in a twin-roll cast Al Mn Fe Si alloy with Zr addition. Al3Zr precipitates, which are known to improve the recrystallization resistance by exerting the Zener drag on migrating grain boundaries ...
