An aneurysm clip is an implant tool for assisting the neurosurgeon in treating acute hemorrhagic stroke and cerebral aneurysm. This equipment stops blood flow of a ruptured or enlarged vessel In development production, titanium alloy most used material selection. Several researchers reported that this metal leads to artifacts during MR (magnetic resonance) CT (computed tomography) imaging. Sinc...

Beeswax (C46H92O) is a naturally derived substance that has the potential to be used as solid fuel for hybrid rocket applications and substitute paraffin wax in rockets. BW burns more efficiently than because of oxygen molecule it contains. The low thermal stability poor mechanical properties limit its practical use upper-stage propulsion applications, these issues are rarely addressed literatu...

The present paper investigated a preparation of Nano sized Mg0.2Fe0.8O by eco-friendly chemical combustion synthesis using magnesium and iron nitrates as oxidizers and the glycine as a fuel to drive the reaction. Powder characterization was carried out by X-ray diffraction (XRD) to estimate crystallite size, Particle Size Analyzer (PSA), Thermal gravimetric analyzer (TGA) for determining sample...

Abstract Nanomaterials and nanocomposites have gained relevance in science technology due to their excellent properties. Therefore, the characterization of these materials is important. Thermogravimetric analysis a powerful technique for iron-carbon nanotubes (Fe/MWCNT) as hybrid nanomaterials, which may be prepared by impregnation step (alkaline or microwave-assisted precipitation). High-resol...

Partial chemical modification of poly(vinyl alcohol) (PVA) was performed through tosylation followed by azidation. Amine functional PVA was also prepared by grafting propargylamine using click chemistry reaction. Through this approach, a tosyl group (a good leaving group), azide group (a group used in click chemistry) and amine group (a group used for amidation) were attached to PVA polymer cha...

Oxidation of ferritic/martensitic steel P92 was investigated in pure oxygen and in pure steam at 600-800 °C by thermogravimetric analysis (TGA), optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The results showed that the oxidation of P92 was significantly enhanced and multilayer scale with an outer iron oxides layer formed in pure steam. At 700 °C, the ...

This work reports the thermodynamic characterizations of organometallic species as a vehicle for the rapid separation of volatile nuclear fission products via gas chromatography due to differences in adsorption enthalpy. Because adsorption and sublimation thermodynamics are linearly correlated, there is considerable motivation to determine sublimation enthalpies. A method of isothermal thermogr...

The high optical transparency glycine maelate crystals were grown by slow evaporation technique at room temperature. The grown crystal was subjected to optical and thermal studies. The optical studies ascertained high optical transparency and cut off wavelength was found to be 361 nm imperative for nonlinear applications. The optical constants, extinction coefficient, refractive index, optical ...
