Application of a new reagent for analysis of oxygen presence in a lowcarbon steel wire rod

A microstructural analysis was performed to determine the presence of oxygen in a wire rod section of AISI 1008 steel with a surface mechanical failure produced during wire *** failure zone was analyzed by comparison using three different attack reagents:alkaline sodium chromate(ASC),ASC with hydrogen peroxide and amyl alcohol,and a solution of nitric acid in ethyl *** reagents were applied in samples in the failure zone,showing different types of zones in regions with internal and superficial defects such as carbides,pores,cracks,deformation,and detachment zones,indicating the possible presence of *** areas identified were observed by means of an optical microscope and were correlated with the content of elements that were present in the region using a scanning electron microscope and a scattered X-ray energy spectrometer,which determined that the areas identified by chromate sodium correspond to regions with a high concentration of oxygen and slag-forming elements such as silicon,aluminum,and iron;this is associated with the presence of oxygen in the oxide *** was also observed that the ASC and the modified ASC solution with hydrogen peroxide and amyl alcohol could identify areas with a high presence of oxides,while the nitric acid solution only identified the steel *** modified ASC solution is an alternative to identify the presence of chemical variants of oxygen because the conventional formulation is unstable and has a too short shelf life,and therefore,its application must be carried out at the time of preparation.

Organometallic Titanium Oxides Obtained by Low-Pressure Plasmas of Water on Titanium Tetrapropoxide

Advances in Materials Physics and Chemistry 2012年第4期2卷 212-218页

作者： F. González-salgado G. j. Cruz M. G. Olayo G. García-Rosales L. M. Gómez Departamento de Física Instituto Nacional de Investigaciones Nucleares Carretera México-Toluca Ocoyoacac México Departamento de Posgrado Instituto Tecnológico de Toluca Metepec México Posgrado en Ciencia de Materiales Facultad de Química Universidad Autónoma del Estado de México Toluca México

This work describes the synthesis of organometallic titanium oxides using low-pressure plasmas of water on titanium tetrapropoxide (TTP) in solid phase with glow discharges in the 0.3 - 0.9 mbar, 100 - 150 W and 60 - 240 min intervals. The accelerated particles in the plasma promoted chemical reactions which produced the partial separation of organic and inorganic parts of TTP with the consequent formation of TiO in organometallic films and particles with photosensitivity. These compounds could hardly be obtained by conventional chemical synthesis. The size of particles was calculated in the 50 - 414 nm interval. The elemental analysis of the titanium oxides indicates that the C/Ti and O/Ti atomic ratios are in the 0.63 - 0.54 and 1.89 - 1.96 intervals respectively, depending on the conditions of synthesis, which suggests that the organic residues are approximately half of the inorganic content. This proportion affects the X-ray diffraction of the organometallic compounds making them essentially amorphous;however, they may have overlapped arrangements resembling some faces of anatase, at 25.3o and 32.5o, and rutile, at 43o, phases. The electrical conductivity of TiO between 20℃ and 100℃ was from 10–10 to 10–12 S/m with activation energy in the 0 - 2.12 eV interval with 3 tendencies associated with temperature.

The Use of Bovine Collagen and Skin Graft for Reconstruction of the Glans Penis Following Cancer Resection

Open j.urnal of Urology 2012年第3期2卷 216-218页

作者： Zhongyi Sun Varsha R. Sinha Ezekiel E. Young Brian Bensadigh Carmen Ceron Bruce R. Kava j.nnifer N. Landon Christopher j. salgado Division of Plastic Surgery DeWitt Daughtry Department of Surgery Leonard M. Miller School of Medicine University of Miami Miami USA

Penile reconstruction following cancer resection has long been a challenge due to demand for both aesthetic and functional preservation. Although various methods have attempted to achieve both goals, none have succeeded entirely. In this report, we introduce a novel reconstructive technique on a 64-year-old patient with squamous cell carcinoma of the glans penis. The technique consisted of two staged procedures. First, a dermal substitute, consisting of bovine collagen, was sutured onto the defect after partial glansectomy and three weeks later, the integrated dermis was covered with autologous non-meshed partial thickness skin graft. Use of this dermal substitute in a staged fashion allowed for ability to await final pathologic margins prior to definitive reconstruction and increased dermal thickness. After 9-month follow-up, sexual function returned within 3 months and the patient remained healed. We found this technique to be useful in concurrently preserving penile function and cosmesis. Future studies should include more patients and longer follow-up.

This work presents a study about the chemical structure of titanium oxide (TiO) particles synthesized by plasmas using titanium tetrapropoxide, Ti(-O-CH2-CH2-CH3)4. In plasmas, practically all chemical bonds are susceptible to participate in the reactions producing different results than those obtained by the traditional chemical routes. The particles obtained this way are semispheres and fibers grouped in random and layered structures in the 120-500 nm interval and mean diameter of 86.4 nm (fibers) and 308.6 nm (semispheres). The analysis of the resulting TiO structure was performed by IR and XPS finding that the main chemical state of Ti in these conditions was O2-Ti-O2 (Ti surrounded by O) which is part of the precursor structure, however, in O, the main chemical state was Ti-O-Ti formed with the rupture of the pre- cursor Ti-O-C bonds. These last bonds reduce the conj.gation between the structure of both elements, O2-Ti-O2 and Ti-O-Ti, to produce organometallic compounds. Other chemical states appeared showing consecutive dehydrogenation steps during the synthesis with the formation of multiple bonds as a consequence of the continuous collisions in the plasma. These results allow us to follow the chemical reactions promoted by this kind of plasmas to produce TiO nanoparticles which are essentially conformed of intensive dehydrogenation.
