We are glad to inform that our Special Issue “Metal Oxide Thin Films: Synthesis, Characterization and Applications” published in Materials is now closed. The last two decades have witnessed the development of new technologies for thin-film deposition and coating. This issue compiles works on vapor-phase deposition processes including ALD and mist-chemical-vapor deposition to the stabilization of metastable phases and the effect of growth conditions. It also includes liquid-phase coatings like sol-gel, solution immersion, micro-arc oxidation, Plasma Electrolytic Oxidation Processing and single pulse anodization. The last paper reports on a new metal oxide thin film characterization method that can extract the majority charge carriers’ type, their concentration, and mobility and is extendable to the study of other wide-bandgap semiconductors. We hope that this special issue will serve as a valuable support for researchers in the field of metal oxide thin-film deposition and characterization and we wish you a pleasant read.

Our application (COVSG-9) to develop new nanocomposites to prevent and limit both rapid contamination of Covid-19 is funded by the Estonian Research Council (ETAg) . This research project will be done at Eesti Maaülikool at the Institute of Technology and the Veterinary Institute and in collaboration with the LBN (Montpellier, France).
“The COVID-19 outbreak requires urgent effective antiviral treatment as well as mitigation of its proliferation. Since 2004, nanomaterials have been investigated towards the development of the so-called ‘nano-antimicrobials,’. Now with COVID-19 pandemic, nanoantivirals have been the focus of investigations. Nanomaterials in antiviral applications and nanotechnology can offer a great support in the design of contamination-safe equipment through metal-loaded nanocomposites. Polymer nanocomposites combining cobalt, copper and silver in polymer matrix will be studied to develop antiviral additives for plastic items production and coatings to protect surfaces (door handles, protective visors, panels…). The technological transfer for industrial production will be done with Estonian Companies. The well-known antiviral properties of various formulations and nanostructures will be studied and exploited to fight COVID-19 and prevent and limit both rapid contamination leading to contagion.”
