We present a setup for directed loading of standard microneedle arrays for transdermal drug delivery with the respective therapeutic agent. The necessity to dose medical drugs according to their particular utilization requires an exact volumetric measure of the particular drug, which is usually provided as a liquid. This is achieved by arranging a ...

We assess the applicability of slip-length models to represent textured superhydrophobic surfaces. From the results of direct numerical simulations, and by considering the slip length from a spectral perspective, we discriminate between the apparent boundary conditions experienced by different lengthscales in the overlying turbulent flow. In partic...

Dans cette thèse, nous avons travaillé sur la mise au point de surfaces superhydrophobes modèles dont la mouillabilité peut être contrôlée par un stimulus externe. Composées de forêts de piliers micrométriques élastomères à forts rapports d'aspect dans lesquels sont incorporées des particules magnétiques, les surfaces présentent, via l'application ...

Le contrôle de la mouillabilité de surface est un enjeu majeur pour le développement de matériaux innovants liés aux nano, bio et smart technologies. La mouillabilité est fonction de deux paramètres majeurs : l’énergie de surface du matériau et sa morphologie. La combinaison de ces deux paramètres est à la base de phénomènes tels que la super/parah...

Macroscopic hollow polymeric particles are attractive materials for various applications such as surgery, food industry, agriculture, etc. However, protocols reporting their synthesis have hitherto made use of organic solvents and/or sacrificial templates, compromising the encapsulation of different bioactive compounds and the process yield. Here, ...

Reducing bacterial adhesion on substrates is fundamental for various industries. In this work, new superhydrophobic surfaces are created by electrodeposition of hydrophobic polymers (PEDOT-F-4 or PEDOT-H-8) on stainless steel with controlled topographical features, especially at a nano-scale. Results show that anti-bioadhesive and anti-biofilm prop...

We analytically construct solutions for the mean first-passage time and splitting probabilities for the escape problem of a particle moving with continuous Brownian motion in a confining planar disc with an arbitrary distribution (i.e., of any number, size and spacing) of exit holes/absorbing sections along its boundary. The governing equations for...

A novel and facile approach like polishing as well as etching followed by dip coating using low surface energy material, perfluoro octyl tri ethoxy silane was attempted to create superhydrophobic (SHP) surface modification on Mod.9Cr-1Mo. A water contact angle (CA) of 150° ± 1° was achieved with advancing angle (θadv) as 163°, Receding Angle (θrec)...

A simple method is reported for the preparation of superhydrophobic fiber reinforced plastic (FRP) surfaces with controlled adhesion. By simply adjusting the content of CaCO3 and SiO2 of surface coating, after surface treatment, we can obtain the different FRP surfaces with diverse morphologies. The results confirm that the FRP samples not only cou...

The superhydrophobic glass fiber-reinforced plastic (GFRP) surfaces are prepared by spray coating a mixture on GFRP surfaces. The mixture is comprised of EPOLAM resin 2008 (EP2008), EPOLAM curing agent 2008-S (EP2008-S), hydrophobic silica nanoparticles (HSNPs), and acetone. By simply controlling the concentration of HSNPs in the mixture, the tunab...
