    Abstract: Aluminium oxide (Al2O3) were mixed with multicomponent such as Zirconia (ZrO2) and Titania (TiO2). The aim of this thesis was to investigate the effect of TiO2 addition to Zirconia Toughened Alumina (ZTA). The physical, mechanical and microstructural behavior was characterized in this research. The percentage of Alumina was 83-85% and Zirconia used... Show More

    Abstract: The changes in the surface chemical properties of SiC suspensions consequent to the addition of polyethylene glycol (PEG) and chitosan, both individually and in the presence of each other were studied. The adsorption densities of PEG and chitosan for SiCwere found to be higher at pH 2-3 and 7-7.5 respectively. The adsorption behaviour in the combin... Show More

    Abstract: New smart coating for towels was developed. Montmorillonite (MT) as clay layers was decorated with silver nanoparticles (AgNPs) of an average size of 32 nm. Developed MT-AgNPs composite were dispersed in commercial binder producing good dispersion coating system. Then the formed coating was coated on two different towels. The mass loadings of montm...

    Abstract: Plasma immersion ion implantation (PIII) of nitrogen has been performed on three austenitic stainless steels namely, Type 304L SS, MnSS-1 (16%Cr-6%Mn-4Ni) and MnSS-2 (16%Cr-9%Mn) with at three different temperatures namely, 250, 380 and 500°C for 3 h. The GXRD studies shows that mixed iron nitride phases were formed along with expanded austenitic, ... Show More

    Abstract: Surface ignition and extinction of very fuel-lean hydrogen-air mixtures on platinum surfaces were modeled using a detailed surface kinetic mechanism and transport phenomena. A stagnation-point flow geometry was employed to study the effect of heat flux, flow velocity, and composition on the surface ignition and extinction. The temperature and conce... Show More

    Abstract: It has been conducted the analysis of IR-absorption spectra of layered single crystals of GaS and GaS <Yb>, irradiated by gamma-quanta with subsequent annealing. It has been found that, a part of impurity atoms, introduced during the growth of crystals, as well as point defects, formed by irradiation, are located in the interlayer space, that... Show More
