The dual role of hydrogen in grain boundary mobility
(Peer reviewed; Journal article, 2023)ABSTRACT The effect of solute hydrogen on shear-coupled grain boundary (GB) migration is investigated with the dislocation-array type Σ25(430)[001] GB and a dual role of hydrogen on GB mobility is unraveled. In the low ... -
Effect of amorphization-mediated plasticity on the hydrogen-void interaction in ideal lattices under hydrostatic tension
(Journal article; Peer reviewed, 2018)A thermodynamic model is derived to study the void nucleation in ideal lattices under hydrostatic tension loading and predicts that the plasticity has to be initiated before homogeneous nucleation of voids. Molecular ... -
Effect of grain boundary on the crack-tip plasticity under hydrogen environment: an atomistic study
(Journal article; Peer reviewed, 2019)It has been found that the plasticity is significantly affected by the hydrogen interstitials in metallic materials. However, the underlying physics responsible for the dislocation/hydrogen interactions is still poorly ... -
Electromechanical characterization of individual micron-sized metal coated polymer particles
(Journal article; Peer reviewed, 2016)Micron-sized polymer particles with nanoscale metal coatings are essential in conductive adhesives for electronics assembly. The particles function in a compressed state in the adhesives. The link between mechanical ... -
Investigation of thermal transport in polymer composites with percolating networks of silver thin films by the flash diffusivity method
(Journal article; Peer reviewed, 2017)The flash diffusivity method, also known as laser flash analysis (LFA), is commonly used to obtain the thermal diffusivity (α) and thermal conductivity (κ) of materials, due to its relative simplicity, rapid measurements, ... -
Thermal transport in silver-coated polymer sphere composites by the bidirectional 3ω method
(Peer reviewed; Journal article, 2022)The bidirectional 3ω method is an electrothermal technique that is commonly used to obtain the thermal conductivity of materials such as liquids, biological samples and pastes. In this work, an epoxy-based adhesive was ... -
Thermoreflectance techniques and Raman thermometry for thermal property characterization of nanostructures
(Peer reviewed; Journal article, 2020)The widespread use of nanostructures and nanomaterials has opened up a whole new realm of challenges in thermal management, but also leads to possibilities for energy conversion, storage and generation, in addition to ...
