“…In this paper, we are interested in photocatalytic performances of transparent, well-aligned and well-controlled TiO 2 NTAs that are grown on glass substrates. TiO 2 in particulate and film forms has been widely used as photocatalyst − . Transparent TiO 2 films are highly sought after in commercial applications such as photoactive coatings on glass or ceramics substrates .…”

Transparent, well-aligned TiO(2) nanotube arrays (NTAs) with controllable dimensions are grown on glass substrates via atomic layer deposition (ALD) of TiO(2) onto free-standing porous anodic alumina (PAA) templates. Photodegradation of aqueous methylene blue (MB) solution and solid stearic acid (SA) film using TiO(2) NTAs of various wall thicknesses are investigated. The Pd functionalized TiO(2) NTAs, with a wall thickness of 15 nm and height of 200 nm, has the highest photodegradation efficiency at 76% after 4 h of UV irradiation. These functionalized NTAs are able to photodegrade MB molecules completely as no obvious demethylated byproducts are observed during the process. It also demonstrates excellent photocatalytic activity for solid contaminants such as SA film. By using the ALD technique, the nanotube wall thickness can be precisely controlled so that it is sufficiently thin to be transparent while sufficiently thick for excellent photocatalytic performances. The transparent TiO(2) NTAs on glass substrates with excellent photocatalytic properties might have potential applications in self-cleaning coating, transparent electronics, and solar cells.

“…Antimicrobial coatings reduce infectious complications to prolong the useful life of devices and implants. A number of methods have been reported for synthesising the antibacterial coatings, such as calcium phosphate, 1,2 hydroxyapatite, [3][4][5] diamond-like carbon, [6][7][8][9][10][11] TiO 2 , [12][13][14] TiN, Al 2 O 3 , 15 etc., as biofilm on a variety of metallic substrates. Electroless Ni-B coating is a new candidate to use in a broad range of industry applications due to its unique properties, such as cost effectiveness, thickness uniformity, good wear resistance, lubricity, good ductility and corrosion resistance and excellent solderability and electrical properties.…”

A surface deposition treatment like electroless Ni–B deposition, which is a new candidate to use in a wide range of engineering applications owing to many advantages, including low cost and good wear resistance, may improve the antibacterial activity and physical properties of stainless steel biomedical devices. In the present study, the structural and antibacterial properties of electroless Ni–B coatings deposited on AISI 304 stainless steels under different deposition conditions were investigated. Escherichia coli, the most important causative organism for infection, were used as the testing bacteria for in vitro test, including incubation at 37°C and 24 h. X-ray diffraction for crystallographic examination and scanning electron microscopy for morphological analysis were also used. The characterisation results showed that the antibacterial activity of the steel substrates deposited with coatings having especially high NaBH4 concentrations (1·2 g L−1), thus being amorphous, was strongly improved. Furthermore, the bactericidal performance difference of the coatings exhibiting cauliflower-like surface morphology was more obvious than that of the others. Electroless Ni–B surface treatment may be utilised for increasing the lifetime of stainless biomedical devices.
