Defect Engineered Single-Layer MoS2 Dendrites as an Efficient Electrocatalyst for Hydrogen Evolution Reaction

Li S., Pasta M., Warner J.H., Xu W., University of Oxford, UK
Dendritic structures display a high density of edge sites, which are electrocatalytically active in hydrogen evolution reaction (HER). However, given that the basal plane of 2H- phase MoS2 synthesized by chemical vapor deposition (CVD) is [...]

Ultrasound-driven viscous streaming, modelled via momentum injection

Attinger D., Packer J., Ventikos Y., University of Oxford, UK
Mixing, particle transport, and lysis of biological cells can be performed in microfluidic chips by actuators based on the controlled motion of a gas-liquid interface. There is strong motivation to develop practical and tractable computational [...]

Nanodroplet Impact on Liquid Substrates via Molecular Dynamics

Kakalis N.M.P., Lussier D., Ventikos Y., University of Oxford, UK
In this paper, several aspects of the dynamic behaviour of liquid nanodroplets impacting on liquid substrates are investigated using molecular dynamics (MD) simulations. We consider liquid droplets of 5-10 nm in diameter, consisting of 7,000 [...]

Cerebral Oxygen Diffusion and Transport, at the Microscopic Level, and BOLD fMRI

Hadjistassou C.K., Moyle K., Ventikos Y., University of Oxford, UK
With the prospect of elucidating the Blood Oxygenation Level Dependent (BOLD) fMRI effect we consider cerebral oxygen transport at the microscopic scale. We concentrate on the transient response of a capillary-tissue system following brain activity. [...]

Energetics of Non-Uniformly Alloyed Ge(Si)/Si(001) Quantum Dots

Cockayne D.J.H., Lang C., Nguyen-Manh D., University of Oxford, UK
We have obtained for the first time quantitative data about the energetics of alloyed Ge/Si Quantum Dots (QDs) from atomistic simulations which take into account the non-uniformity of the alloying profile. With the algorithm we [...]

The Atomic Limit of Finite Elements in the Simulation of Micro-Resonators

Rudd R.E., University of Oxford, UK
We describe developments in the coupling of length scales methodology which allows the simulation of the dynamic and temperature dependent behavior of sub-micron Micro-Electro-Mechanical Systems (MEMS). This novel technique accurately models the behavior of the [...]

Simulation of Porous Si and SiOx Layer Growth

Briggs G.A.D., Burlakov V.M., Sutton A.P., Tsukahara Y., University of Oxford, UK
Monte Carlo simulation of deposition of amorphous SiOx layer on a polymer surface is reported. The model developed is based on the network properties of silica and takes into account dangling bonds arising during the [...]
