cadmium oxide (cdo) nanoparticles were prepared by precipitation method using cadmium acetate and ammonia solution. presence of chemical species, were verified by fourier transform infra red (ftir) spectrum. from x-ray diffraction (xrd) spectrum the particle size, d-spacing value and structure of the nanoparticle were analysed. size of the nanoparticles and the elemental composition were detect...

biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish myofibril protein. the film forming solution containing 1.5%, 2% and 2.5%(w/v)myofibril protein isolate of 100ml solution and glycerol a...

objective: the aim of this study was to evaluate and compare the effect of dental surface treatment with er:yag , nd:yag ,co2 lasers and sodium ascorbate to recently laser bleached enamel by scanning electron microscope (sem). methods: 15caries-free extracted human third molars were selected for this study. the samples were bleached by heydent jw power activated by diode laser 810 nm. after 7 d...

A new technique for performing corneal endothelial cell autoradiography with the scanning electron microscope is presented. The scanning electron microscope is able to detect silver grains deposited over tritiated thymidine--labeled nuclei of regenerating corneal endothelium.
