The study was carried out to evaluate and compare dentine margin microleakage of nano-filled resin composite restorations placed with a RMGIC using the co-cure technique and those placed with an ‘all-in-one’ self-etch DBA. In premolar teeth, that had to be extracted for orthodontic reasons, two proximal boxes with gingival margins placed in dentine were prepared. Restorations were inserted usin...

the mixed metal nanocomposite mgo∙al2o3∙zno has been prepared by coprecipitation method. the product was characterized by xrd. the average particle size was found to be 34.89 nm from xrd data. sem and sem-eds were studied for evaluating surface morphology and elemental composition. the ftir spectrum of prepared mixed metal nanocomposites mgo∙al2o3∙zno and mgo∙al2o3∙zno-curcumin were studied. th...

Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

Recent studies have paid particular attention to polymer-nanoparticle composite materials considering they a number of interesting properties, which include optical, thermal, electrical, and others (Reyna-Gonzalez et al., 2009; Yakuphanoglu 2010). In this study, free radical polymerization process was used create copolymer N-vinylcarbazole (NVC) benzyl methacrylate (BZMA) at 25–75 mol% each. Th...

Anisotropic nanostructures of metals are extensively studied due to their sizeand shapedependent properties and interesting growth mechanisms. Usually materials based on noble metals are investigated in this context, although anisotropic nanostructures of other transition metals are also prepared. Spherical as well as anisotropic magnetic nanoparticles are of great interest due to potential app...

Co-Cr and Co-Cr/nano-TiO2 coatings were electrodeposited from Cr(III) based baths. The effect of TiO2 nano-particles incorporation on the morphology, structure, crystallite size, and preferred orientation was studied. Corrosion behavior of the composite coating was also investigated by means of polarization and electrochemical impedance spectroscopy techniques in Hanks’ si...

This study aimed to identify biological contaminants of banana in vitro cultures. We also tested the effect of Zn or ZnO nanoparticles on elimination of some bacterial and fungal contaminants and their influence regeneration. Nine strains of bacterial contaminants (Cellulomonas uda, Cellulomonas flarigena, Corynebacterium panrometabolum, Bacillus megaterium, Staphylococcus spp., Klebsiella spp....

Nano-sized ZnO catalysts were prepared by a direct precipitation method under the optimal conditions (calcination of precursors at 550 ̊C for 120 min). The as-synthesized ZnO catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-Vis spectroscopy. The photocatalytic properties of ZnO nanoparticles were investigated via methyl orange (MO) as a model org...
