Studies on the synthesis, Structure and Properties of Amine - Templated Arsenate frameworks
Amine-templated open-framework gallium arsenates with one- (I), two- (II and IV) and three-dimensionally (III–V) extended structures have been isolated and characterized. The exclusive presence of only one type of SBU in ... -
Novel layered and network metal oxides: synthesis and characterization.
The present investigation shows that reaction of electropositive metal iodides with the transition-metal oxides containing reducible cations affords a novel route for the synthesis of oxide bronzes as well as lower valence ... -
Electronic structure and Photophysical study of semiconducting nanocrystallites
Sizable photocurrent was observed from the CdS-4.5 and CdS-2.2 nanocrystalline films, although the EL efficiency was weak. The I-V characteristic of CdS-4.5 and CdS-2.2 has a typical diode behavior with the onset voltage ... -
Transport properties of binary mixture
In this paper, we have presented molecular dynamics (MD) simulations and mode coupling theory (MCT) calculations of the composition dependence of viscosity in binary mixtures. We have proposed two models to capture the ... -
Modeling the solar magnetic cycle
The intriguing variety of activities displayed by the Sun naturally awakens human curiosity. Also, by virtue of its physical proximity, the Sun serves as an excellent astrophysical laboratory for testing our theoretical ... -
Electronic analogue methods in X ray Crystallography
Among the advantages of the structure factor computer described here are the following: (i) Use of standard components throughout, and very little wiring requirements, thus ensuring great ease in mass production. (ii) Very ... -
Investigating Nucleosynthesis During Formation of Black Holes and Extracting Their Properties
Measurement of black hole spins is of great interest to physicists in general and to astrophysicists in particular, as this provides a direct proof of the theory of general relativity for rotating black holes. It involves ... -
Advanced wavefront sensing algorithms in astronomical adaptive optical syatems
Atmospheric turbulence limits the quality of imaging in ground-based astronomical telescopes (Hart; 2010). To obtain diffraction-limited imaging, there is a need for a technology that removes the effects of atmospheric ... -
High rydberg state recombination lines from interstellar carbon : an observational study
This thesis describes the results of an observational study of partially ionized gas in the Galaxy using low-frequency radio recombination lines of carbon, which arise due to electronic transitions at large quantum numbers ...
