To reduce a film-diffusional resistance in the very vicinity of the photocatalyst surface, titanium oxide particles containing a small amount of adsorbent particles (310 %) are immobilized on a stainless steel screen by a spraying method and its performance is investigated by decomposing 2,4-dinitrophenol in water. It is found that the activity of this photocatalyst screen is higher than that o...

Stainless steel reinforcing has an elevated chloride threshold and is an attractive alternative for prestressed concrete applications. However, due to the high strength requirements for prestressing strands, concern exists about the possibility of stress corrosion cracking (SCC). This investigation screened for potential SCC development three candidate high strength alloys for use as prestresse...

Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coat...

The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...

The basic calcium phosphate mineral, hydroxyapatite (HAP) (Ca10(PO4)6(OH)2)), is the prototype of one of the major constituents of bone and teeth. Thin layers of HAP were coated on the surface of type 316L stainless steel by electrophoretic deposition (EPD) from a 2.5% suspension in isopropyl alcohol, and this was followed by vacuum sintering at 800uC for 1 h. The development of HAP coatings wa...

This conference paper presents a series of electron cloud measurements in the Fermilab Main Injector and Recycler. A new instability was observed in the Recycler in July 2014 that generates a fast transverse excitation in the first high intensity batch to be injected. Microwave measurements of electron cloud in the Recycler show a corresponding dependence on the batch injection pattern. These e...

Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...
