Broadband antireflection and field emission characteristics of silicon nanopillars (Si-NPs) fabricated by self-masking dry etching in hydrogen-containing plasma were systematically investigated. In particular, the effects of ultrathin (5-20 nm) titanium nitride (TiN) films deposited on Si-NPs by atomic layer deposition (ALD) on the optoelectronic properties were explored. The results showed tha...

Axial plasma spray is one of the thermal techniques to deposit multifunctional advanced coatings. The present work explores use this process thin, continuous, and adherent Ca5 (PO4)3OH (hydroxyapatite, HAp) coatings characterize its microstructure, phases, hardness adhesion strength. Three different suspension-deposited HAp were investigated compared with powder-deposited coating on a Ti6Al4V s...

There is increasing demand to functionalize meso- and nanoporous materials by coating and make the porous substrate biocompatible or environmentally friendly. However, coating on a meso-porous substrate poses great challenges, especially if the pore aspect ratio is high. We adopted the pulsed laser deposition (PLD) method to coat Ni(3)Al-based meso-porous membranes, which were fabricated from a...

Nanosized TiO2 particles were prepared by sol–gel method. The TiO2 particles were co-deposited with chromium using electrodeposition technique. In investigating of coating surfaces by scanning electron microscope (SEM), the results showed that the morphology of the coating surface was changed by adding TiO2 nanoparticles to the chromium coating. The corrosion behavior of the coatings was assess...

Introduction Indium tin oxide (ITO) is a commonly used transparent conducting oxide (TCO) with applications as a transparent electrode for flat panel displays [1], photovoltaic devices [2] and as an infrared mirror in energy saving windows [3]. ITO offers the best combination of electrical conductivity and visible light transmission with excellent environmental stability, reproducibility and su...

A twin surface dielectric barrier discharge is used for the catalyst-enhanced plasma oxidation of 300 ppm n-butane in synthetic air. Plasma-only operation results conversion into CO and CO2. Conversion improved by increasing temperature feed gas, but selectivity shifts to undesired CO. ?-MnO2 as a catalyst deposited on electrodes spray coating with distance 1.5 mm between uncoated grid lines sq...

A novel method for the facile fabrication of conformal, ultrathin, and uniform synthetic amino acid coatings on a variety of practical surfaces by plasma-enhanced chemical vapor deposition is introduced. Tyrosine, which is utilized as an agent to reduce gold nanoparticles from solution, is sublimed into the plasma field and directly deposited on a variety of substrates to form a homogeneous, co...

In order to increase the bone bioactivity of metallic implants, hydroxyapatite (HA: Ca10(PO4)2(OH)6) is often coated on their surface so that real bond with surrounding bone tissue can be formed. In present study, HA coatings were deposited on AISI 316L SS and titanium using shrouded plasma spray process. The coated specimens were subjected to X-ray diffraction (XRD) analysis, field emission sc...

Polymeric glazing and mouldings are an extremely high “want” from the transportation community, enabling more creative designs as well as improved part consolidation。 However, plastic windows and mouldings must have high-performance and low-cost protective coating systems with lifetimes in excess of 10 years. Current polymeric glazings do not meet durability/performance requirements for near-te...
