Area selective atomic layer deposition of titanium dioxide: Effect of precursor chemistry

Novel Antimicrobial Titanium Dioxide Nanotubes Obtained through a Combination of Atomic Layer Deposition and Electrospinning Technologies

The search for new antimicrobial substances has increased in recent years. Antimicrobial nanostructures are one of the most promising alternatives. In this work, titanium dioxide nanotubes were obtained by an atomic layer deposition (ALD) process over electrospun polyvinyl alcohol nanofibers (PVN) at different temperatures with the purpose of obtaining antimicrobial nanostructures with a high s...

Introduction to (plasma-enhanced) atomic layer deposition

Film growth by the atomic layer deposition (ALD) method relies on alternate pulsing of the precursor gases and vapors into a vacuum chamber and their subsequent chemisorption on the substrate surface (Fig. 1) [1,2]. The different steps in the process are saturative such that ALD film growth is self-limiting yielding one submonolayer of film per deposition cycle. ALD has some unique characterist...

Methylene Blue Immobilized on Cellulose Acetate with Titanium Dioxide: an Application as Sensor for Ascorbic Acid

Neste trabalho, o corante azul de metileno foi imobilizado na superfície do acetato de celulose modificado com dióxido de titânio produzindo um material híbrido sólido denominado de CA-TiO 2 MB. O experimento produziu uma quantidade de 1,8 mmol g de TiO 2 incorporado no acetato de celulose e uma quantidade de 0,170 0,005 mmol g de azul de metileno adsorvido na superfície do CA-TiO 2 . Um eletro...
