The primary aim of this review article is to discuss superplasticity in ceramics and their composites at high temperatures. Superplastic ceramics including yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP), alumina (Al2O3), silicon nitride (Si3N4), hydroxyapatite (Ca10(PO4)6(OH2)) and Fe-Fe3C system compositi…
In this work, different computational methods such as HF, B3LYP, range separated functionals (CAM-B3LYP and LC-BLYP) with 6-31G* basis set were applied to investigate the electronic, spectroscopic and nonlinear optical properties of L-threoninium picrate (LTHP) molecule for the first time. The calculated values of IR…
The objective of this research was to evaluate the mechanical damage on TiO2 nanotubes upon implantation in an ex vivo manner mimicking the surgical implantation procedure. TiO2 nanotubes were grown on cp-Ti rods using anodization method and then the rods were implanted into the bone for the damage study. Silver was e…
This chapter focuses on the synthesis of Y2/3Cu3Ti3.9Fe0.1O12 (YCTFO) sample by the semi-wet route at a relatively lower sintering temperature and its dielectric and electrical properties were studied. Polycrystalline phase of YCTFO is characterized by XRD. Scanning electron micrograph reveals the presence of smooth s…
Ti2AlC belongs to the interesting group of ternary materials called MAX phases which can be found in the Ti-Al-C-N system. Thanks to the heterodesmic chemical bonding these nanolaminate structured materials possess unique set of properties locating them between metals and ceramics. One of the best methods of obtaining…
Steady increase of the chips integration, general increase in the layout density of elements and devices for electronic equipment leads to the search for improved design and technological solutions by microminiaturization electronic products. This chapter presents a technology for creating multi-pins bare chips with b…
In this thesis, we explore the electronic, dynamic and thermoelectric properties of different tellurium-based compounds. We perform ab-initio calculations within the Vienna Ab-initio Simulation Package (VASP) that works in the framework of Density Functional Theory (DFT). For the thermoelectric properties, we use the…
Fiber reinforced composites containing a ZrB2 matrix is prepared by reactive melt infiltration, using a Zr based intermetallic compound. Different precursors are evaluated in order to manufacture fiber reinforced preforms and enable a melt infiltration process. In order to infiltrate the porous preform, capillary forc…

A radioactive waste glass melter is a challenging environment for the materials of construction (MOC) due to the combination of high temperatures, chemical attack, and erosion; therefore, highly engineered materials must be selected for this application. The degradation or corrosion of these materials is one of the ma…
Gallium and iron-containing magnetic nanoparticles (MNP's) were synthesized by sol-gel method using different ratios of Fe:Ga (1:1, 2:1. 3:1, 4:1) followed by heat treatment at 500 °C for 1 h. The in vitro bioactivity assessment of MNP's was performed using a simulated body fluid (SBF), while their heating capacity wa…
A new methodology is developed that provides repeatable control the microstructure of Pb-free solder joints in an effort to prevent tin whisker formation. Tin whisker formation causes electronic failures in a variety of industries resulting in billions of dollars in lost equipment. This chapter introduces application…
Low accuracy of the Solvation Free Energy (SFE) calculation is a known problem of the numerical methods of the Integral Equation Theory of Liquids and the Classical Density Functional Theory (Classical DFT). Although functionals with empirical corrections can essentially improve the predictability of the methods, thei…
Cerium oxide nanoparticles have shown great potential as antioxidant and radioprotective agents for applications in cancer therapy. The surface chemistry of nanoparticles has a significant effect on their performance in biological applications. Recently, various nanosized polymer-coated cerium oxide preparations have…
This chapter summarizes the recent activities concerning maturation (ground/flight testing) of blanket based TPS, metallic TPS and oxide/silicon carbide CMC based TPS. AIRBUS D&S GmbH, Bremen focused recently on further maturation of its comprehensive TPS portfolio. Within the European demonstrator programs the blanke…
X-ray computed tomography is an invaluable tool for studying internal structure and composition of complex engineering systems such as TBCs. However, before meaningful results can be obtained and quantified, several parameters have to be optimized and measures have to be adopted to enhance reliability and reproducibil…
A crystal-tolerant glass approach is being developed for the Waste Treatment and Immobilization Plant at the Hanford Site in Washington State with a goal to maximize the loading of high-level waste in borosilicate glass without jeopardizing melter operation by crystal accumulation in the melter discharge riser. The re…
Titania (TiO2) nanostructures were produced via hydrothermal method using amorphous TiO2 powders synthesized by the sol-gel precipitation process. The hydrothermal system was isolated from the environment and hydrothermal reactions were allowed to execute at 130 °C for 36 h at autogeneous pressure, and at a stirring r…
We demonstrate a magnetometry technique using nitrogen-vacancy centres in diamond which makes use of coherent two-photon transitions. We find that the sensitivity to magnetic fields can be significantly improved in isotopically purified diamond. Furthermore, the long-term stability of magnetic field measurements is si…
Gas turbine engines have a working temperature as high as 1200°C to improve the energy efficiency and power output. Thus, thermal barrier coatings are applied to reduce the temperature of the superalloys. The coatings also prevent corrosion and degradation caused by molten calcium-magnesium-aluminum-silicon oxides (CM…
