nanocrystals of zno were prepared by microwave irradiation using zn (ii) acetate and triethanol amin (tea) as the starting materials and water as solvent. the nanocrystals of zno with hexagonal (wurtzite) structure were characterized by x-ray powder diffraction (xrd), transmission electron microscopy (tem), scanning electron microscopy (sem), uv-vis absorption and ftir spectroscopy techniques.
Po protein, the dominant protein in peripheral nervous system myelin, was studied immunocytochemically in both developing and mature Schwann cells. Trigeminal and sciatic nerves from newborn, 7-d, and adult rats were processed for transmission electron microscopy . Alternating 1-lam-thick Epon sections were stained with paraphenylenediamine (PD) or with Po antiserum according to the peroxidase-...
A central requirement for the subcellular localization of synthesized and/or endocytozed lipoproteins is the availability of antibodies against the antigen to be localized. The preparation of cells for electron microscopy, in particular the fixation and embedding routine, influences the antigenicity, often resulting in a markedly reduced labeling intensity. To ameliorate fixation-induced change...
in the present work, we report a suitable approach for the preparation of batio3 nanostructures via the hydrothermal condition using dolapix et85 as surfactant. the powders were investigated by x-ray diffraction (xrd), scanning election microscopy (sem), energy-dispersive x-ray spectroscopy (edax), field emission transmission electron microscopy (fetem), selected area electron diffraction (saed...
introduction: the purpose of this study was to evaluate the morphologic surface of guttapercha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...
Background: Scorpion envenomation is considered as one of the Public Health problems in some countries in the world including Iran. Annually, approximately 30,000 scorpion stings happen in Iran from which 12% belongs to Hemiscorpius lepturus (special small closely spaced, bead-shaped jointed tail, similar in the shape to a cows tail, and is locally called ‘‘gaodim'' (Gao, cow dim, tail)) with 9...
in this work, a novel hg2+ sensitive fluorescent chemosensor is constructed. the proposednano-chemosensor was prepared through the preparation of 3-(benzo[d]thiazol-2-yl)-7-hydroxy-2h-chromen-2-one functionalized silica nanoparticles which has high magnetization properties (btc-fe3o4@sio2). theûnal product was characterized by fourier transform infrared spectroscopy (ft-ir), thermal gravimetric...
Antibodies represent a major component of the mammalian immunological defense against picornavirus infection. The work reviewed here examines structural details of antibody-mediated neutralization of human rhinovirus 14 (HRV14) using a combination of crystallography, molecular biology and electron microscopy. The atomic structures of the Fab fragment from a neutralizing monoclonal antibody (Fab...
