The inductance gradient is one of the important parameters on the design and evaluation of railgun performance. The size, shape, and material of rails have effects on the inductance gradient. In 2-D analysis, the length of rails assumed to be infinite and then the effect of the armature ignored and a constant inductan…
Ceramics are increasingly used in the fields of aerospace, communication, mechanical and modern biomedical engineering. With high hardness, strength and abrasive resistance, the machined ceramic components are most likely to contain surface/subsurface damages, influencing strongly the performance and reliability of ce…
We investigate the structural response of SrTiO 3 when Cooper pairs are broken in an epitaxially grown YBa 2 Cu 3 O 7 top layer due to both heating and optical excitation. The crystal structure is investigated by static, temperature-dependent and time-resolved x-ray diffraction. In the static case, a large strain fiel…
Abstract Various star‐shaped poly(phenoxy propylene sulfide)s (PPSs) bearing curable end groups were synthesized by the functionalization of the propagating ends of star‐shaped poly(PPS) with various electrophilies. The functionalization with chloromethyl styrene proceeded quantitatively, and afforded polymers with Mn…
A simple micromechanism-inspired rheological model is developed that incorporates the serrated flow nature of metallic glasses subjected to compressive deformation at room temperatures. The process of propagation and the arrest of shear bands were addressed in this model. Shear-induced nanocrystallisation was believed…
Abstract— Multi‐view spatial‐multiplexed autostereoscopic 3‐D displays normally use a 2‐D image source and divide the pixels to generate perspective images. Due to the reduction in the resolution of each perspective image for a large view number, a super‐high‐resolution 2‐D image source is required to achieve 3‐D imag…
The use of magnetic and magnetic/gold core/shell nanoparticles in biotechnology or medicine has shown good promise due to their hybrid nature which possesses superior magnetic and optical properties. Some of these potential applications include hyperthermia treatment, bio-separations, diagnostics, drug delivery and to…
Abstract The relation between electric and mechanical properties of dielectric elastomers allows using them as energy convertors under some conditions. The process is based on the relations between mechanical and electrical energy stored on the material. In this work, cycles of maximal mechanical energy to be converte…
Partial discharge (PD) monitoring is an effective predictive maintenance tool for electrical power equipment. As a result, an understanding of the theory related to PD and the associated measurement techniques is now necessary knowledge for power engineers in their professional life. This paper presents a modular cour…
The velocity distributions of the fragments produced by dissociative photoionization of C(60) have been measured in the extreme UV region for the first time, by using a flight-time resolved velocity map imaging technique combined with a high-temperature molecular beam and synchrotron radiation. Values of the average k…
Abstract We report a detailed study of the effect of deposition parameters on optical, structural, and morphological properties of InN films grown by reactive radio‐frequency (RF) sputtering on GaN‐on‐sapphire templates in a pure nitrogen atmosphere. Deposition parameters under study are substrate temperature, RF powe…
Extreme water repellency is greatly desired for microfluidics and self-cleaning applications. Post-like aligned carbon nanotube (CNTs) films were grown on the Ni-coated Si substrates by a plasma enhanced chemical vapor deposition (PECVD) technique. The surface of morphologies of the pretreated Ni thin films were inves…
Magnetic flux distributions of the permanent magnet (PM) section and the homopolar induction (HI) section in a hybrid excitation synchronous generator (HESG) are calculated by using the finite element method (FEM). The influences of the axial-length ratio of the two sections on the back EMF, inductance, and terminal c…
Abstract Novel bioengineering functional terpolymers were synthesized by complex‐radical terpolymerization of N‐isopropylacrylamide (NIPA), 3,4‐dihydro‐2H‐pyran (DHP) and maleic anhydride (MA) with α,α′‐azoisobisbutyronitrile (AIBN) as a radical initiator in 1,4‐dioxane at 65 °C under nitrogen atmosphere. Structure co…
BACKGROUND: Liposomes incorporating peptide from the Plasmodium circumsporozoite protein (CSP) accumulate rapidly and selectively in adult mouse liver. PURPOSE: The development of the liposome-binding pattern in liver and spleen was studied in relationship to the development of extracellular matrix molecules. METHODS:…
Abstract We use density functional theory to investigate the optical properties of vacancy di‐nitrogen, vacancy–nitrogen–hydrogen and vacancy di‐hydrogen defects. The first is a common defect found in irradiated natural type IaA diamonds while the second is found in as‐grown CVD diamond. The last has not yet been dete…
We introduce a computational scheme to analyze second harmonic generation in periodic metallic nanostructures, i.e. metamaterials, that are composed of multiple layers. To describe the nonlinear polarization by the metallic constituents, we rely on a hydrodynamic model for the conduction electrons. Our computational a…
As world water demand continues to grow there is a critical need to develop sustainable water treatment solutions. This chapter describes the potential for nanomaterials to improve the sustainability of water treatment. Nanomaterial-driven advances in disinfection, oxidation, membrane separation and groundwater remedi…
It is the aim of the paper to present a new point of view on rotational elasticity in a nonlinear setting using orthogonal matrices. The proposed model, in the linear approximation, can be compared to the well known equilibrium equations of static linear elasticity. An appropriate kinetic energy is identified and we p…
Abstract Several novel poly(pyridinium salt)s with heterocyclic pyridine moieties in their backbones with tosylate and triflimide counterions were prepared by either ring‐transmutation polymerization reaction of phenylated‐bis(pyrylium tosylate) with isomeric pyridine diamines of 4‐phenyl‐2,6‐bis(4‐aminophenyl)pyridin…
