Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction [PDF]

open access: yesAdvanced Science
High‐entropy boride ceramics hold great promise as ultra‐high‐temperature structural materials but are hindered by the well‐known strength‐toughness trade‐off.

Surface Neuronal-Like Structuring of High-Strength CFRP for Enhanced Electromagnetic Interference Shielding. [PDF]

open access: yesAdv Sci (Weinh)
This study elucidates the microstructural evolution at the material interface of Ni‐plated plain‐weave carbon fiber fabric following vacuum heat treatment at 500°C–900°C under different current densities, as well as the mechanism underlying the synergistic enhancement of electromagnetic shielding and ductility.

Mutual Diffusion of Model Acceptor/Donor Bilayers under Solvent Vapor Annealing as a Novel Route for Organic Solar Cell Fabrication

open access: yesEnergies, 2022
The fabrication of bulk heterojunction organic solar cells (OSCs) is primarily based on a phase demixing during solution deposition. This spontaneous process is triggered when, as a result of a decrease in the solvent concentration, interactions between ...

New Analyzing Approaches for In Situ Interdiffusion Experiments to Determine Concentration-Dependent Diffusion Coefficients in Liquid Al–Au

open access: yesMetals, 2021
Interdiffusion coefficients are key parameters for the solidification process of liquid alloys. However, the determination of interdiffusion coefficients in liquid metals at high temperatures is a challenging and extensive task, due to a variety of ...

Interdiffusion in r-component (r ≥ 2) one dimensional mixture showing constant concentration [PDF]

open access: yesComputer Methods in Materials Science, 2008
It is shown that multicomponent nonequilibrium system relaxing by a diffusion process exhibit unique behavior during evolution toward stationary state. The Darken’s postulate that the total mass flow is a sum of diffusion flux and translation are applied

Strain and interdiffusion in semiconductor heterostructures [PDF]

open access: yesPhysical Review B, 1994
It is often suggested that the rate of interdiffusion at semiconductor heterostructure interfaces may be strongly dependent on elastic strain in the structure. Experimental and theoretical results show that strain does not, and should not, affect interdiffusion.

Formation of L10-ordered CoPt during interdiffusion of electron-beam-deposited Pt/Co bilayer thin films on Si/SiO2 substrates by rapid thermal annealing

open access: yesMaterials Research Express, 2020
Preparation of ordered CoPt on Si substrates is significant for expanding future applications of spintronic devices. In this study, ordered CoPt alloys including the L 1 _0 phase with a maximum coercivity of 2.1 kOe are formed in electron-beam-deposited ...

Molecular Dynamics Study of Interdiffusion for Cubic and Hexagonal SiC/Al Interfaces

open access: yesCrystals, 2022
The mechanical properties of the SiC/Al interface are crucial in estimating the overall strength of this ceramic-metal composite. The present work investigates the interdiffusion at the SiC/Al interface using molecular dynamics simulations. One cubic and
