Shock wave emission upon spherical bubble collapse during cavitation-induced megasonic surface cleaning.
Description :
When a gas bubble in a liquid interacts with an acoustic wave near a solid surface, the bubble first expands and then collapses. In this paper, a mathematical framework combining the Gilmore model and the method of characteristics is presented to model the shock wave emitted at the end of the bubble...

Protein surface properties using signal processing and statistical tools
Author(s) :
Giard, Joachim
Description :
This thesis is dedicated to the study of protein structure properties using 3D image processing tools. Proteins are macromolecules that rule almost every life processes by interacting with other molecules. The comprehension and the prediction of the interaction mechanisms, namely, protein docking, i...

Influence of Surface-properties of Carbon-black On the Activity of Adsorbed Catalase
Description :
Homologous series of carbon samples were prepared from a non-porous thermal carbon black by oxidation with various concentrations of hydrogen peroxide at 95 degrees C. The samples were characterized by X-ray photoelectron spectroscopy, gas adsorption, and electrophoretic mobility measurement; the en...

Surface of lactic acid bacteria: relationships between chemical composition and physicochemical properties.
Description :
The surface chemical composition and physicochemical properties (hydrophobicity and zeta potential) of two lactic acid bacteria, Lactococcus lactis subsp. lactis bv. diacetilactis and Lactobacillus helveticus, have been investigated using cells harvested in exponential or stationary growth phase. Th...

Cell adhesive PET membranes by surface grafting of RGD peptidomimetics.
Description :
A non-peptide mimic of the Arg-Gly Asp (RGD) active sequence of adhesive proteins (such as vitronectin) has been equipped with two different spacer-arms for surface anchorage. The covalent grafting on poly(ethylene terephthalate) (PET) membrane was realized via the activation of the hydroxyl polymer...

A practical molecular clip for immobilization of receptors and biomolecules on devices' surface: synthesis, grafting protocol and analytical assay.
Description :
Deposition of O-succinimidyl 4-(p-azido-phenyl)butanoate (4) onto inorganic device (FTIR-ATR crystal) or polymer material (filtration membrane) followed by irradiation at 254nm led to surface functionalisation with NHS esters. Further reaction with biomolecules allowed their covalent grafting. The r...

Description :
The surface of polystyrene substrates has been modified by wet chemistry consisting of a treatment with sodium hydroxide in a water-methanol solution at 50 degrees C for 15 h, under air atmosphere. The resulting samples were analyzed by XPS and AFM. The surface functional groups (hydroxyl and carbox...

In situ evaluation of density, viscosity, and thickness of adsorbed soft layers by combined surface acoustic wave and surface plasmon resonance.
Description :
We show the theoretical and experimental combination of acoustic and optical methods for the in situ quantitative evaluation of the density, the viscosity, and the thickness of soft layers adsorbed on chemically tailored metal surfaces. For the highest sensitivity and an operation in liquids, a Love...

Description :
We report on a simple procedure to tune the hydrophilicity of hybrid gold nanoparticles. The nanoparticles have been prepared in the core of a poly(ethylene glycol)-block-poly(epsilon-caprolactone) (PEG-b-PCL) five-arm star block copolymer. A hydrophilic corona was then added to these hybrid gold na...
