This chapter contains sections titled: Principles of Radiography Use of Radiopaque Materials in Medical Devices Radiopaque Fillers Types of Radiopaque Fillers Other Radiographic Materials and Coating Systems Radiopaque Coatings by Physical Vapor Deposition Challenges in Producing Radiopaque Coatings Using PVD Gold Rad…
As for the fuel cladding in the light-water reactor, silicon fiber reinforced silicon carbide composite (SiC/SiC composite) is expected as a potential replacement of Zircaloy due to its many superiorities, where it is necessary to develop the end-cap seal of SiC/SiC composite cladding. In this research, as one possibl…
The Kansas Department of Transportation (KDOT) has designed and constructed numerous mechanically stabilized earth (MSE) walls to support new and expanded highway projects throughout Kansas. MSE walls often contain galvanized steel strips as mechanical reinforcement within layers of specified backfill material. Inclus…
The current status of high performance SiC/SiC component R & D by Nano Infiltration and Transient Eutectic (NITE) method is introduced. Start with the brief history of NITE SiC/SiC R & D, the recent efforts on heat resistant SiC/SiC component R & Ds are presented. The combustion cycle test results between 1350C and 20…
This article presents a systematic theoretical enquiry concerning the conceptual foundations and the nature of phonon-mediated electron-electron interactions. Starting from the fundamental many-body Hamiltonian, we propose a simple scheme to decouple the electrons and nuclei of a crystalline solid via effective intera…
Ultrafast optical heating of the electrons in ferrimagnetic metals can result in all-optical switching (AOS) of the magnetization. Here we report quantitative measurements of the temperature rise of GdFeCo thin films during helicity-independent AOS. Critical switching fluences are obtained as a function of the initial…
A novel environmental barrier coating system for oxidation/corrosion protection of steel consisting of a perhydropolysilazane (PHPS) derived bond coat and a polysilazane-based glass/ceramic composite top coat has been under investigation. The work was aimed at development of a relatively thick, protective, dense and w…
The development of ceramic and metal-ceramic components with graded microstructures concerning material or porosity opens new fields of application. Components with different porosities combine different properties in the gradient structure regarding thermal conductivity and capacity, density, mechanical strength, and…
Dense sintered B4C is an attractive material for a variety of critical applications in different industries. Using sintering aids is a typical approach to help increase the relative density. SiC is one of the common additives for this purpose. In this study, spark plasma sintering (SPS) technique was used to sinter B4…
The lightweight Al2O3-MgO castable with micro-porous aggregates is of importance for energy-saving and consumption reducing in refining ladle, and the slag corrosion resistance is significantly concerning its service life. For lightweight porous castable, a method, in which aggregates and matrix were described with di…
Nuclear waste generated during nuclear power production and other applications of nuclear technology requires safe storage and disposal. As a consequence, significant research effort is devoted to development of methods and materials that could be used for conditioning and disposal of long-lived radionuclides. We cont…
The Mark–Houwink–Sakurada (MHS) equation allows for estimation of rheological properties, if the molecular weight is known along with good understanding of the polymer conformation. The intrinsic viscosity of a polymer solution is related to the polymer molecular weight according to the MHS equation, where the value o…
We performed systematic ab initio atomistic simulations of monazite (LnPO4) and pyrochlore (A2B2O7 )-type ceramics. The simulated properties include the thermodynamic parameters, the threshold displacement energies, the elastic constants and the energies of defects formation. We computed the excess effects of mixing i…
We have investigated structural, electrical, and magnetic properties of single crystals of modified pyrochlore fluorides ${\mathrm{Rb}}_{}{\mathrm{V}}_{2}{\mathrm{F}}_{6}$ and ${\mathrm{Cs}}_{}{\mathrm{V}}_{2}{\mathrm{F}}_{6}$, which have mixed-valent V atoms. At room temperature, they have orthorhombic structures. Wi…
The results of investigations carried out to improve the quality of the CO2 welding process with an additional filler wire (AFW), fed into the tail part of the molten pool in the cold state, are presented. The effect of the AFW on the quality of the produced bead is studied. The results of metallographic studies of th…
The influence of external stress (0-800bar) on the dielectric properties of PLZT x/65/35 (2≤x≤13) ceramics was investigated. Applying uniaxial pressure leads to a change in the peak intensity of the electric permittivity (ϵ), of its frequency dispersion as well as in the dielectric hysteresis. The peak intensity of ϵ…
Polylactide (PLA) was plasticized with poly(diethylene glycol adipate) (PDEGA). The plasticized PLA was further blended with core-shell structured particles of glycidyl methacrylate-functionalized methyl methacrylate-butyl acrylate copolymer (GACR) using a twin-screw extruder, and the extruded samples were blown using…
A novel strategy for the synthesis of CoSb 2 nanoparticles is demonstrated via preparation of novel organometallic complexes.Hydrated cobalt oleate (CoOl) and non-hydrated antimony oleate (SbOl) complexes are synthesized as precursors.The CoSb 2 nanoparticles are prepared by hot injection, which involves thermolysis o…
The effects of surface plasmon oscillations on the radiative recombination rate and internal quantum efficiency of silver coated CdSe/ZnS quantum dots imbedded in quartz matrix is studied theoretically and numerically. The analysis is carried out by introducing the local field enhancement factor for the description of…
