Spectroscopic studies on polymerized and doped fullerenes and pressure induced phase transition in BaTiO3
In conclusion, we have observed pressure induced polymerization in the case of C but not in C . This calls for detailed theoretical analysis, incorporating the changes in electronic structure with the application of ... -
Bulk and thin growth of pure and substitued indium antimonide for infrared detector applications
InSb single crystals were grown by the vertical and horizontal Bridgman techniques. About 81 experimental runs were carried out altogether (for 8 mm, 10 mm and 20 mm diameter InSb crystals). Among them, as many as 47 runs ... -
Investigations of electroporation physics using optically transparent polymer devices and molecular dynamics simulation
New technologies have emerged in the medical field over the last decade to treat problems such as cancer and tumors. Electroporation is one such technique that has been extensively used in electrochemotherapy, drug delivery, ... -
Design and performance testing of a PC-based control system for nuclear waste vitrification
The high computing and informationprocessing power of a General Purpose Digital Computer (GPDC) in the form of a Personal Computer (PC) has become available throughout the world, leading to the emergence of the PC as a ... -
Studies on design parameters and construction of parabolic trough concentrators for an industrial process heat system
Line focus solar concentrating collector systems of the parabolic trough type with single axis tracking are being increasingly used for Industrial Process Heat (IPH) applications such as the production of process steam and ... -
Amorphous hydrogenated silicon microstructure analysis and effect of plasmons on solar cell performance
Hydrogenated amorphous silicon (a?Si:H), a well?known material for photovoltaics, thin?film transistors, MEMS, etc., is most extensively deposited using the PECVD technique, which is well studied and is primarily used in ... -
Crystal structure of a light-harvesting protein C-phycocyanin from spirulina platensis and bioinformatics analysis of beta-bulge turns in proteins
The conclusions for the crystal structure of light-harvesting phycobiliprotein, C-phycocyanin from an important cyanobacterium, Spirulina platensis, are summarized as follows: We have solved the three-dimensional structure ... -
Investigations of AC response in certain type II superconductors
We have intentionally varied the microstructures of polycrystalline YBCO samples and studied their AC loss behavior. A close correlation between AC losses and the microstructures of the superconducting samples is observed. ... -
Study of electromechanical and optoelectronic behavior of carbon nanostructures
Electric field induces a large actuation (up to 14-30%) in bulk CNT cellular structure. The actuation is symmetric, polarity independent, non-instantaneous, and directly proportional to the square of the applied electric ... -
Investigations in X-ray crystallography
he crystal structure of glycine silver(I) nitrate has been solved in the non-ferroelectric phase by the heavy atom technique and refined to an R value of about 11% with four sets of intensity data, three sets collected at ... -
Theoretical study on localization and transport in disordered systems
It is hard to conclude and give constructive critical remarks on a subject, especially at a stage when all the “easy” things have been done and the “hard” things left untouched. As mentioned in the Introduction, what is ... -
Femtosecond time domain spectroscopy and nonlinear optical properties of iron pnictide superconductors and nanosyatems
In a broad sense, ultrafast laser pulses (pulsewidth ?t < 1 ps) have three important applications: (i) Inducing a perturbation in a system of study within a time much shorter than the characteristic lifetimes of the system ... -
Instabilities coarsening and chaos in driven systems : Growing interfaces and sheared wormlike micelles
We now provide a summary and outlook of the various topics discussed in this thesis. This thesis deals with systems driven far from equilibrium. Such systems show many interesting phenomena, notably nonequilibrium phase ... -
