Surface morphological studies

The aim of this study was to design and characterize a NdFeO3-based photocatalyst prepared by sol-gel method for treatment of oily wastewater. Different characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophometer were used to elucidate the structure, morphology, surface functional groups, and optical absorption properties of the prepared NdFeO3 photocatalyst.

Non-metallic C, N, and S doped TiO2 materials were prepared using the hydrothermal method from titanyl sulfate solution with different doped precursors. The influence of non-metallic elements on crystal structure, morphology, surface area, bonding state, and light absorption ability of materials was studied through XRD, SEM, BET spectra, and UVis - DRS.

We report a facile process to fabricate cuprous thin films by thermal oxidation of copper substrates. Structure and phase identification were studied by X-ray diffraction measurement and Raman spectroscopy. Scanning electron microscopy was utilized to study surface morphology of the as-fabricated thin films and optical properties of the samples were investigated by diffused reflectance spectroscopy.

Present study was conducted on the humerus bones of five adult Indian tigers. The shaft was a four sided structure upto the one third of its length, after which it became three sided because of merging of the anterior surface distally. Olecranon fossa was heart shaped and had several foramina. Greatest length of humerus was (33.62 cm) approximately three times than mid-shaft diameter of the humerus (10.88 cm).

In this study, the electrochemical behavior of carbon steel surface treated in H2ZrF6/silane solution was investigated. The impact of immersion time on the morphology and the composition of ZrO2/silane film was evaluated and the effect of ZrO2/silane pretreatment on corrosion protection of powder coating was studied.

Cotton bamboo fibers were prepared by mechanical method and their diameter were about 9- 26 µm. Surface composition and morphology of fibers were studied. The analytic result shown that most of hemicellulose and lignin were removed. There is a strong and sharp peak in the untreated bamboo spectra at about 1736 cm-1 corresponding to carbonyl group (C=O), but this peak disappeared in alkaline treated bamboo spectra. Epoxy composites reinforced cotton bamboo fiber have been developed with varying fiber contents.

Nanoparticle of Perovskite La1-xSrxCoO3 (x = 0, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7) were prepared by using citric acid sol-gel method. The structure and morphology of products were investigated by X-ray difraction (XRD) and transmission electron microscopy (TEM). The specific surface area (BET) was determined by N2 adsorption/desorption at 77 K. The catalytic oxidation of propene and removal NOx were studied by Temperature Program Surface Reaction (TPSR) over every compositions. The results show that the contened of substituted ion Sr2+ influenced on the oxidation temperature of propene.

Immunophenotype and Relevance to the WHO Classification The immunophenotype of human leukemia cells can be studied by multiparameter flow cytometry after the cells are labeled with monoclonal antibodies to cell-surface antigens. This can be important for separating AML from acute lymphoblastic leukemia (ALL) and identifying some types of AML. For example, AML that is minimally differentiated (immature morphology and no lineage-specific cytochemical reactions) is diagnosed by flow-cytometric demonstration of the myeloid-specific antigens cluster designation (CD) 13 or 33.
