Absorption and near-infrared emission properties of Bi-doped “powder-in-tube” fabricated fibers were compared with the bulk glass samples of the same Mg-Al-silicate glass composition. The losses in the fibers were an order of magnitude less than in Ir crucible melted glasses.
The micro-structure of systems with competition often exhibits many universal features. In this thesis, we study certain aspects of these structural features as well as the microscopic interactions using disparate exact and approximate techniques. This thesis can be broadly divided into two parts. In the first part, w…
Experimental results are presented on the development of a high explosive (HE) suitable for the welding of thin metallic foils. The explosive is formed from a mixture of brisant HE (RDX or PETN) and an inert material, namely sodium bicarbonate. Sodium bicarbonate releases a rather large quantity of gas during decompos…
The microstructure of the cast iron materials for sintering machine trolley is analyzed by the optical microscope,scanning electron microscopy (SEM),X-ray diffraction(XRD) and the energy dispersive spectroscopy (EDS). The results show that the austenite, carbide and some martensite are contained in the microstructure…
The mean-field approximation predicts pairing and shape phase transitions in nuclei as a function of temperature or excitation energy. However, in the finite nucleus the singularities of these phase transitions are smoothed out by quantal and thermal fluctuations. An interesting question is whether signatures of these…
Recent research results on a green LED and solar cell based on ZnTe are reported. The wall plug efficiency of ZnTe LED has been improved to 0.15% by adopting a thin film structure, which is comparable to that of GaP-based green LED. The solar cell based on ZnTe with an efficiency of 1.42% has also been developed. The…
This paper presents the results of preparing and investigating the solid solutions of the formulae (Pb1-xLax)(Zr1-yTiy)O3, where x = 0.03 or 0.06, y = 0.9, (PLZT) and (Pb1-xLax)[(Zr1-yTiy)1-zSnz]O3, where x = 0.04, y = 0.9, z = 0.02, 0.04, 0,06, 0,08, (PLZTS). These materials belong to perovskite type oxygen octahedra…
The kinetics of aniline oxidative polymerization has been studied by the potentiometric technique. This is the first time that a kinetic model of oxidative polymerization has been constructed as a heterogeneous autocatalytical process. The change in the degree of rate of aniline oxidative polymerization has been deter…
Lifetime of an indium tin oxide (ITO) target is an important characteristic in the production of liquid crystal displays (LCDs). Increasing the sintering density of the ITO target is assumed to lead to an increased lifetime. So far, it has been clarified that the carbon concentration in In2O3 powder, the raw material…
Fast ion conducting system (SbI3)0.3 - (Ag2CrO4)0.7 containing 0.3 mole fraction SbI3 was synthesized by rapid melt-quenching method. The open circuit voltage, (OCV) measured for the solid state primary electrochemical cell fabricated using the above best conducting composition (SbI3)0.3 - (Ag2Cr04)0.7 is found to be…
We demonstrate efficient mode convertors for guided transverse electric (TE) and transverse magnetic (TM) modes on sub-wavelength plasmonic waveguides. Efficient mode conversion is important for realization of multi-functional optical nanocircuits and surface plasmon amplification.
This study presents a technique to fabricate monolithic, low-index guided-mode resonance filters by means of conventional photolithography. Linear and hexagonal grating geometries achieved narrowband resonance while demonstrating control over polarization dependence.
The chemiluminescence (CL) emission spectra of luminol were recorded using Fuss spectrograph in different aqueous aliphatic amines using sodium persulphate alone and mixture with hydrogen peroxide as an oxidant. The CL emission spectra after resolution showed two emission bands at 425 and 455 nm. The CL mechanism was…
Theoretical works have predicted that the thermal conductance of a deformed 1D system will start to decrease when the radius of curvature (Rc) is comparable to the phonon mean free path (l). However, due to limited mechanical strengths and short phonon mean free paths of most materials, no experimental works are capab…
The μLSF is a micro-plastic forming method with the laser-induced shock load generated by the plasma in confined medium. It is characterized in the high-pressure and ultra-high strain ratio. This paper developed the model of metal micro-bulk forming by laser shock, simulated the process of forming and compared the inf…

Abstract This report looks into the application and feasibility of manufacturing natural composite canoes. The main fabrics that were analyzed are flax, hemp, and jute. These were then compared to carbon fiber and fiberglass to see the difference in mechanical properties. It was found that the natural fibers have lowe…
The microstructure, mechanical properties and damage morphology of as-cast and as-extruded AZ31 Mg alloy under different annealing treatments were investigated. The result of three-point bending test showed that the as-extruded magnesium alloy after annealing treatment followed by 300°C×30min can obtain a good mechani…
We theoretically investigate using of Chalcogenide glasses in a metamaterial structure and obtain an intensity dependent magnetic permeability. We also numerically investigate the role of the dielectric used in a fishnet metamaterial structure at microwave wavelengths.
Single-Molecule Magnets (SMMs) are complexes in which the individual molecules act as discrete magnetic domains. As such they are potential candidates for nano-scale data storage and processing. However, it can be difficult to tailor the structural and magnetic properties of an SMM because modifying a component may le…
