Studies on porous iron electrodes for alkaline storage batteries and supplementary investigation on porous lead electrodes of lead-acid
It has been demonstrated that an analysis of the open-circuit transients is useful for understanding several aspects of the alkaline iron electrodes. It provides diagnostic criteria for studying the effect of additives. ... -
A Study of electronic structure and semiconductor-metal transitions in perovskite oxides
In this chapter we discuss the semiconductor-metal transition in La???Sr?CoO?. We study the electrical resistivity, X-ray photoelectron spectroscopy (XPS), Ultraviolet photoelectron spectroscopy (UPS), Auger electron ... -
Computer simulation studies of ionic motion in nasicon-type superionic conductors
In summary, a new interionic potential function for Li? with the Zr?(PO?)? framework of the LiZr?(PO?)? system, consisting of three terms-Coulombic, repulsive, and charge-polarizability interaction-has been proposed. ... -
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 ... -
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 ...
