A cyclic olefin copolymer (COC) is a thermoplastic polymer endowed with glass-like optical transparency, unique biocompatibility, low autofluorescence, good chemical stability, and excellent water vapor barriers. COC promising new material for optics, medical devices, nanotechnology, microelectronics. The applicability of the depends on its modification through different techniques from plasma ...

Smicrostigma warmwaterbergense is described from the summit of Warmwaterberg on Little Karoo Western Cape. It resembles S. viride in its habit and leaves but differs that flowers open during day close at night reproductive parts are fully visible when open. The new species highlights links to Octopoma Zeuktophyllum, which also centered share with a smooth surface, solitary, (sub-) sessile many-...

The in vitro adsorption kinetics of lung surfactant at air-water interfaces is affected by both the composition of the surfactant preparations and the conditions under which the assessment is conducted. Relevant experimental conditions are surfactant concentration, temperature, subphase pH, electrolyte concentration, humidity, and gas composition of the atmosphere exposed to the interface. The ...

Molecular dynamics simulations are used for studying the contact angle of nanoscale sessile drops on a planar solid wall in a system interacting via the truncated and shifted Lennard-Jones potential. The entire range between total wetting and dewetting is investigated by varying the solid-fluid dispersive interaction energy. The temperature is varied between the triple point and the critical te...

The influence of molecular weight asymmetry across an interface on the transient behavior of the interfacial tension is investigated for two different polymer combinations, polybutadiene (PBD)/polydimethylsiloxane (PDMS) and polybutene (PB)/PDMS. This choice ensures a minor diffuse interface using the first combination and a very diffuse interface in the latter case. Measurements of the interfa...

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. 1. Introduction Mammalian fertility analysis is an important industrial issue because of the selection for breeding. This is one reason, beside fundamental interest, for which many studies analyse the individual motion of the spermatozoon (Gaffney et al. 2...
