Interdiffusion in Nb-Mo, Nb-Ti and Nb-Zr systems

, 2012
Diffusion couple technique is used to study interdiffusion in Nb-Mo, Nb-Ti and Nb-Zr systems. Interdiffusion coefficients at different temperatures and compositions are determined using the relation developed by Wagner.

Nanoscale Confinement Enhances Ultrafast Demagnetization

Advanced Science, EarlyView.
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

Stress-Strain Behavior and Microstructural Evolution of Hot-Pressed Paper Webs Revealed by X-Ray Tomography

BioResources
The mechanical performance of fiber-based materials depends not only on strength but also on elongation, which is particularly critical in converting and end-use applications.

Interdiffusion von Heterostrukturen auf Antimonidbasis

, 2002
Interdiffusion in alloys based an the GaSb-AlSb material system that is suitable for optoelectronic devices for the infrared range is investigated quantitatively and is interpreted in terms of an atomistic model . To this end, nominally undoped GaSb/Al$_{

Orientation‐Engineered Insulator‐Metal Transition in Vanadium Dioxide

Advanced Science, EarlyView.
Crystallographic orientation engineering in VO2/TiO2 heterostructures enables tunable insulator‐metal transitions. The high‐Miller‐index (102) orientation breaks in‐plane mirror symmetry, inducing anisotropic transport, while its inclined oxygen channels accelerate protonation kinetics.

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Numerical Model of Radical Photopolymerization Based on Interdiffusion

International Journal of Polymer Science, 2014
An accurate reaction model is required to analyze the characteristics of photopolymers. For this purpose, we propose a numerical model for radical photopolymerization.

Effects of Si Addition on Interfacial Microstructure and Corrosion Resistance of Hot-Dip Zn–Al–Mg–Si Alloy-Coated Steel

Crystals
Alloy coatings protect steel from corrosion in various applications. We investigated the effects of Si addition on the microstructure, electrochemical behavior, and corrosion resistance of steel sheets coated with a hot-dip Zn–Mg–Al–Si alloy using a ...

Strain-induced morphological evolution and preferential interdiffusion in SiGe epitaxial film on Si(100) during high-temperature annealing

, 1999
Strain relaxation in initially flat SiGe film on Si(1 0 0) during rapid thermal annealing is studied. The surface roughens after high-temperature annealing, which has been attributed to the intrinsic strain in the epilayers.
