Enhanced drug efficiency of doped ZnO–GO (graphene oxide) nanocomposites, a new gateway in drug delivery systems (DDSs)

Materials Research Express, 2020
Graphene oxide (GO) nanosheets were doped to zinc oxide (ZnO) nanoparticles using a facile chemical deposition method. X-ray diffraction (XRD) confirmed the presence of hexagonal structure and increased peaks broadening upon doping. Undoped and ZnO doped

Augmentation of wear-protective coatings for non-ferrous alloys by the addition of Cr and Ni elements [PDF]

Materials Research, 2014
A number of Al-, Mg- and Ti-base alloys were preconditioned by oxidation via Plasma-electrolytic oxidation (PEO) followed by the addition of Cr and Ni elements in the coating pores by chemical precipitation and a final stage of mechanical treatment.

Modeling and Simulation of a Chemical Vapor Deposition [PDF]

Journal of Applied Mathematics, 2011
We are motivated to model PE‐CVD (plasma enhanced chemical vapor deposition) processes for metallic bipolar plates, and their optimization for depositing a heterogeneous layer on the metallic plate. Moreover a constraint to the deposition process is a very low pressure (nearly a vacuum) and a low temperature (about 400 K).
