Researchers have been focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the Electrochemical Impedance Spectroscopy (EIS) method. EIS is a technique used for evaluating coating permeability or barrier performance based on the electrical imped...

Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...

This work addresses two ways of loading proteins on microchannel surfaces for immunoassay applications: the "stop-flow" and the continuous flow processes. The "stop-flow" method consists of successive static incubation periods where the bulk solution depletes upon the adsorption process. In the present paper, a multi-step "stop-flow" protein coating is studied and compared to a coating under co...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

and light microscopy were used to identify the changes after the heat-treatment. Microhardness and indentation modulus values were also investigated to analyse the changes in the mechanical properties after the heat-treatment. Results of this investigation indicated that the residual stress gradient within the coating material decreases after the heat-treatment, and the stress field in the subs...

Hot-melt coatings (HMC) are widely used to provide drug protection, to increase aesthetic value of products, to reduce acidity if vitamins, to provide lubrication and modified drug release. In hot-melt coating the substrates are coated with molten form of coating materials. Substrates used for coating are beads, capsules, granules, pellets, pills, spherules and tablets. Hot-melt coating devoid ...

Minimally invasive restorative techniques can be applied with direct resin composites. However, the preparation for an indirect restoration tends to lead to over-treatment of the tooth structures. A resin-coating technique has been proposed in which both a hybrid layer and a tight sealing film are produced on the dentin surface with a dentin adhesive system and a low viscosity micro-filled resi...
