Laser cladding (LC) is a laser-based surface modification technology that has been widely adopted for the development of thin layers operate under harsh conditions. Corrosion contributes to approximately 50% oil and refinery equipment failures. These major risks require sophisticated methods improve performance. LC promotes generation superior properties on substrate surface, which improves ser...

the effects of a prolonged oral administration of methylthiouracil was studied on the electrophoretically - separated serum protein fractions in 24 dogs. though the statistical mean of changes in serum albumin and alpha2 globulin were highly significant but the individual alterations were not consistent and therefore on the basis of the available data there does not seem to be a characteristic ...

As orthopaedic and dental metallic implant materials, titanium and titanium alloys are widely used due to their relatively low modulus, good fracture toughness, excellent strenthto-weight ration, and superior biocompatibility and corrosion resistance (Long and Rack, 1998). They have become the first choice above all other candidate metallic implant materials such as Co-Cr-Mo alloys, stainless s...

dye sensitized solar cell was fabricated from a double layer photoanode. first, tio2 nanoparticles  were synthesized by hydrothermal method. these tio2 nps were deposited on fto glasses by electrophoretic deposition  method in applied voltage of 5 v and epd time of 2.5-10 min. then tio2 hollow spheres (hss) were synthesized by sacrificed template method with carbon spheres as template and ttip ...

background: meat products may be unacceptably tough because of the high connective tissue content of meats used in their manufacture. objective: the aim of this study was using meat acid marination method on some physicochemical and sensory characteristics of beef burgers. methods: meat was marinated in three concentrations (0.5%, 1% and 1.5%) of lactic and citric acid solutions (1:4 w/v) at 4 ...

Abstract Carbon nanoparticle coatings on laser-patterned stainless-steel surfaces present a solid lubrication system where the pattern’s recessions act as lubricant-retaining reservoirs. This study investigates influence of structural depth line patterns coated with multi-walled carbon nanotubes (CNTs) and onions (COs) their respective potential to reduce friction wear. Direct laser interferenc...

Ni–Ti shape memory alloys (Nitinol) are suitable for biomedical applications such as orthodontic, orthopedic, and cardiovascular implants. However, to avoid local inflammatory processes, efforts being made functionalize the surface of alloy with bioactive materials. Chitosan-based composite coatings can be applied improve properties due their excellent properties, low toxicity, biocompatibility...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...
