A lattice Boltzmann model for self-diffusiophoretic particles near and at liquid-liquid interfaces

Ignacio Pagonabarraga Mora

We introduce a novel mesoscopic computational model based on a multiphase-multicomponent lattice Boltzmann method for the simulation of self-phoretic particles in the presence of liquid-liquid interfaces. Our model features fully resolved solvent hydrodyna ...

Derivative voltammetry: a simple tool to probe reaction selectivity in photoelectrochemical cells

Kevin Sivula, Nukorn Plainpan, Florent Alexandre Boudoire

We demonstrate the use of the derivative voltammogram method to predict the selectivity of the photo-driven oxidation of 5-hydroxymethylfurfural (HMF) on a WO3 photoanode as a function of applied potential using only information obtained from the linear sw ...

Design and modelling of a compliant constant-force surgical tool for objective assessment of ossicular chain mobility

Simon Nessim Henein, Charles Baur, Loïc Benoît Tissot-Daguette

Surgeons generally assess the mobility of the ossicle chain by manual palpation using rigid elongated hooks inserted through the ear canal. As the applied forces are in the range of a few grams equivalent force, the measurement remains subjective and its r ...

Variants in USP48 encoding ubiquitin hydrolase are associated with autosomal dominant non-syndromic hereditary hearing loss

Nicolas Jean Philippe Guex

Non-Syndromic Hereditary Hearing Loss (NSHHL) is a genetically heterogeneous sensory disorder with about 120 genes already associated. Through exome sequencing (ES) and data aggregation, we identified a family with six affected individuals and one unrelate ...
