Study of Gas Permeation Through Thin ta-C:H Films
Protective ultra-thin barrier lms gather increasing economic interest for controlling permeation and di usion from the biological surrounding in implanted sensor and electronic devices in future medicine. Thus, the aim of this work was the investigation of the lm thickness in uence on the gas permeation barrier of ultra-thin, cytocompatible tetrahedral amorphous carbon (ta-C:H) lms on polyimide...
متن کاملBlood Brain Barrier Permeation
The large surface area and the short diffusion distance from capillaries of the blood brain barrier (BBB) to the neurons facilitate the drugs and nutrients access to the brain. Penetration of chemicals to the BBB occurs using a combination of intra and intercellular passages. Tight junctions regulate the intracellular passage of molecules according to their physicochemical properties (e.g. lipo...
متن کاملOn gas permeation in PDMS
A theoretical model of gas permeation in polydimethylsiloxane (PDMS) is conducted for two prior works involving MEMS sensors and actuators. The issue for modeling a sensor is about using PDMS slabs to replace Pyrex glass as the packaging substrate for bulk-micromachined pressure sensors. The leakage pressure due to gas permeation in PDMS reveals the time-varying behavior of exponential decay. T...
متن کاملIn silico prediction of blood-brain barrier permeation.
This review examines the progress that is being made towards the in silico prediction of brain permeation. Following a brief introduction to the blood-brain barrier, the datasets currently available for in silico modeling are discussed. Recent developments in in silico models of brain permeation are summarized in the context of the current state of the art in prediction accuracy. An analysis of...
متن کاملNonequilibrium water permeation in Si0 2 thin films
d;r, _:0 films by thermal treatments in steam. Thermal oxides were grown on silicon to a t ,ickntss of 260 nm in dry 02 and were subsequently treated in steam at temperatures of 320 and 500"C for periods lasting between 390 and 6 X 10' s. The concentrations of hydrogen carried in by permeating water were then profiled with 6.4 MeV "N ions using the resonant nuclear reaction 'H(1N, ay)"C. Water ...
