Optical methods have been used for the sensitive characterization of surfaces and thin films for more than a century.The first ellipsometric measurement was conducted on metal surfaces by Paul Drude in 1889.The word 'ellipsometer' was first used by Rothen in a study of antigen-antibody interactions on polished metal s…
This paper presents a theoretical investigation of electromagnetic wave coupling and tunneling through chiral-chiral interfaces. The dispersion relation, conditions of the trapped modes, and evanescent wave coupling and tunneling in an optically active chiral slab and chiral ambient medium are derived. The transfer ma…
In this study, bubbled- armour forms are assessed for ballistic penetration resistance. A key component is optimization of the bubble shape to maximize its fundamental modal frequency. A ‘large- plastic- regime’ automotive steel alloy is adopted for the bubble and the penetration process simulated by LS- DYNA for a ‘r…
The authors have studied the co-winding coil method (CW method) using the co-wound coil electrically insulated from the HTS coil. In this method, the quench is detected by the voltage difference between the coil of the HTS tape (HTS coil) and the coil of the normal conductor (CW coil). The voltage induced in the CW co…
This thesis covers the applications of one dimensional nanostructured materials in energy storage devices such as lithium-ion batteries (LIBs) and micro-supercapacitors (MSCs). Besides energy storage devices fabrication, integration of energy storage devices with microelectronic devices is also included. The chapter 1…
Aptamers are known to undergo adaptive conformational change upon ligand binding, causing micro-environment rearrangements that may be linked with stilbene transducers.
The influence of low pressure on the surface potential decay of gamma irradiated polymer films of polypropylene (PP) and poly(ethylene terephtalate) (PET) were studied. Polymer film samples were subjected to integral irradiation doses (Ey = 1.25 MeV, 60 Co source) of 5 kGy and 25 kGy accumulated in air at a dose rate…
Poly (L-lactic acid) (PLLA) and glucose (Glu) were respectively dissolved in N, N-dimethyl acetamide to prepare solutions. The blends of PLLA and glucose with various ratios were prepared by mixed solution method, and characterized with infrared Fourier transform spectrometry, differential scanning calorimetry, therma…
The elemental composition of surfaces is of great importance for the understanding of many surface processes such as catalysis. For a reliable analysis and a comparison of results, the quantification of the measured data is indispensable. Positron annihilation induced Auger Electron Spectroscopy (PAES) is a spectrosco…
ZnO nanowires (NWs) have attracted tremendous attention in the past 15 years after the first demonstration of optically pumped ultraviolet laser by Yang et al. he global lightening market calls for

Ricinoleic acid grafted amphiphilic carboxymethy chitosan (CMC-g-RA) was synthesized as a carrier to load botanical drug rotenone (Rot). Then Rot/CMC-g-RA water dispersion in nanoscale was prepared, whose shape, zeta potential, loading efficiency and outdoor stability were characterized accordingly. The results indica…
Preparation and percutaneous absorption of 2-methyl-2-perfluoro-2-methyl-3-oxoca-proyloxyl ethoxycarbonyl ethylmethyldipolyethoxylsilicane (V) were investigated. V was synthesized from 2-perfluoro-2-methyl-3-oxocaproyloxylethyl methacrylate and methyldichlorosilicane by hydrosilication, then by alcoholysis with polygl…

The evolution of volume porosity previously obtained by using the existing low temperature high burn-up gaseous swelling model with progressive recrystallization for UO2 fuel is utilized to study the degradation of irradiated UO2 thermal conductivity calculated by the FRAPCON model of thermal conductivity. A porosity…
The aim of this research is to demonstrate achievements and difficulties of using large amplitude Fourier transformed (FT) alternating current (AC) voltammetry for measurement of the electrode kinetics of fast electron transfer processes. Research is focussed on study of outer-sphere electron transfer processes at ele…
The storage of solar energy into chemical bonds, such as hydrogen or hydrocarbon fuels, through system mimicking photosynthesis is attracting intensive attention at the moment as a potential pathway to provide cheap and affordable source of renewable energy. The obstacle for the practical application of the artificial…
Scattering properties of meta-surfaces for plane wave incidences can successfully be analyzed using their own transmission line models (TLMs). The main idea of the TLM is the decomposition of a periodic structure into a frequency selective surface (FSS) or a meta-film and dielectric slab as a spacing medium between th…
A three-dimensional reinforced concrete frame structure under diluted debris flow impact was established using explicit dynamic analysis finite element software LS -DYNA. The dynamic damage distribution and stress redistribution process of the structure under the impact were calculated and analyzed. The results show t…
A VecDec4SAS program has been developed to provide a fast and easy description of the dynamics of any process occurring in a nanoparticle solution observed by the small-angle scattering technique. The process should be characterized by the some conditional initial and final stages, in fractions of which all intermedia…
