Layer-by-Layer (LbL) is a method which can be used for nanoscale coating and surface functionalization of a material. LbL technique mainly uses the electrostatic attracting between charged materials (polyelectrolytes, nanoparticles, etc.) and an oppositely charged surface. In this study, protein separation (BSA) from lactose solution was carried out using the LbL self-assembly method, which was...

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...

A study of the i-layer porosity as a function of the deposition parameters by PECVD technique, is presented here. It is demonstrated in particular, that for a fixed deposition rate of 2 Ays, increasing the plasma power tends to increase the layer ̊ density, while increasing the pressure tends to increase the layer porosity. Regarding the cells, no correlation between the layer density and the in...
