Effect of nano TiO2 particles on the corrosion properties of an epoxy based coatings was investigated. Coatings and nano Titania were applied on standard phosphated steel panels by cathodic electrodeposition simultaneously. The coated panels were immerged in 3.5 NaCl solution for 2880 hours 120 days. The SEM and EIS technique were used to investigate the electrodeposion of nano Titania particle...

A successful synthetic tissue engineering scaffold requires a hierarchical internal structure with interconnecting pores for nutrition transportation, cell infiltration and vascularization as well as nanoscale surface features favorable for cell attachment and long-term functions. However, traditionally, fabricating macro-scale scaffolds in a defined manner from nano-scale constituents has prov...

pure anatase titania (tio2), mixed 1.0 wt.% cerium-anatase titania (1.0 wt.%ceo2-tio2), and mixed 1.0 wt.% zirconia-anatase titania (1.0 wt.%zro2-tio2) nano powders were synthesized by co-precipitation method and characterized using x-ray diffraction (xrd), brunauer-emmett-teller (bet) surface area analysis, uv-vis diffuse reflectance spectroscopy (drs), and transmission electron microscope (te...

an efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured zno, nano-g-alumina and nano-zsm-5 zeolites, as the catalyst. the optical properties of the nano-structured catalysts and organic molecules were studied. the advantages of ...

background: heavy metals in aquatic systems usually interfere with many beneficial uses of water. divalent nickel is a commonly occurring toxic metal in natural ecosystems due to the effluent of refineries, electroplating, and casting industries. in aquatic environments, nickel appears as ni (ii) and ni0. despite the high reported toxicity for ni (ii), ni0 is only slightly toxic. various method...

Titania nano particles were synthesized at carbon paste electrode by cyclic voltammetry and then it was employed for the determination of acetaminophen in phosphate buffer at pH 7.4. Carbon paste electrode with titania nano particle displayed excellent electrochemically catalytic activities by shifting the oxidation potential of acetaminophen towards the negative side. The mass transfer process...

Titania coated silica spheres (SiO2@TiO2) prepared by heterocoagulation of silica and titania nano-particles were investigated as catalyst in he photodegradation of rhodamine B (RB) in aqueous solution. The silica spheres were prepared by the well-known Stöber method and titania ol by a hydrolysis–condensation reaction in acidic media. The uncoated and coated particles were characterized by zet...

Seaweeds, being prolific sources of bioactive components have garnered unprecedented interest in recent times. The complex polysaccharides from the brown, red and green seaweeds possess broad spectrum therapeutic properties. Especially, the sulfated polysaccharides, viz. fucans, carrageenans and ulvans have exhibited strong antioxidant, antitumor, immunostimulatory, anti-inflammatory, pulmonary...
