Self-directed growth of AlGaAs core-shell nanowires for visible light applications

, 2007
Al(0.37)Ga(0.63)As nanowires (NWs) were grown in a molecular beam epitaxy system on GaAs(111)B substrates. Micro-photoluminescence measurements and energy dispersive X-ray spectroscopy indicated a core-shell structure and Al composition gradient along ...

Enhanced spin-orbit coupling in core/shell nanowires [PDF]

, 2016
The spin-orbit coupling (SOC) in semiconductors is strongly influenced by structural asymmetries, as prominently observed in bulk crystal structures that lack inversion symmetry.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Magnetic interaction effects in Fe3O4@CoFe2O4 core/shell nanoparticles

Journal of Science: Advanced Materials and Devices
The magnetic properties of core/shell nanoparticles (NPs) depend on the various parameters, including the magnetic interactions, but these effects have not been well studied.

Bioinspired Tough and Strong Fibers with Hierarchical Core–Shell Structure

Advanced Materials Interfaces, 2023
Strong and tough bio‐based fibers are attractive for both fundamental research and practical applications. In this work, strong and tough hierarchical core–shell fibers with cellulose nanofibrils (CNFs) in the core and regenerated silk fibroins (RSFs) in

Synthesis of core/shell quantum dots for diagnostic [PDF]

, 2014
In this paper, synthesis of colloidal core and core/shell quantum dots (QDs) was described. First, CdTe QDs capped with glutathione, thioglycolic or mercaptopropionic acid were prepared in aqueous phase, and used for synthesis of colloidal core/shell ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Ge/Si core/shell quantum dots in alumina: tuning the optical absorption by the core and shell size

Nanophotonics, 2017
Ge/Si core/shell quantum dots (QDs) recently received extensive attention due to their specific properties induced by the confinement effects of the core and shell structure.

The Ab Initio No-core Shell Model [PDF]

Few-Body Systems, 2009
This contribution reviews a number of applications of the ab initio no-core shell model (NCSM) within nuclear physics and beyond. We will highlight a nuclear-structure study of the A = 12 isobar using a chiral NN + 3NF interaction. In the spirit of this workshop we will also mention the new development of the NCSM formalism to describe open channels ...
