Chemical Modulation of Ferroptosis in Mammalian Cells by Synthetic Organoselenium and Gold-based Small Molecules
Oxidative stress induced by reactive oxygen species (ROS) plays a crucial role in triggering various forms of cell death, including apoptosis, autophagy, and necrosis. In recent years, a distinct and regulated form of cell ... -
Ultrafast Photophysics of Aminoboranes by Transient Absorption and Ultrafast Raman Loss Spectroscopy
B–N based aminoboranes systems have recently emerged as promising materials for organic optoelectronic and biomedical applications. They exhibit a wide range of functionalities such as delayed fluorescence, room-temperature ... -
Chemistry of hydrazine derivatives
The chemistry of hydrazine and its derivatives is of interest because of their use as rocket fuel, solid propellant oxidizers, explosives, antioxidants, insecticides, food preservatives, pharmaceuticals and materials for ... -
Kinetic studies on the interactions of gold (iii) with nucleic acids
The effects of the univalent ions like Li?, Na?, K?, Cs?, etc. and their counter ions on the CD spectra of various DNA samples have been investigated in some detail. With the increase in the concentration of the univalent ... -
Contributions to the chemistry of thiophosphoryl fluoride
The present status of knowledge about the chemistry of thiophosphoryl fluoride has been reviewed in the introductory chapter. Taking this background into consideration, a line of investigation has been undertaken which is ... -
Thermal studies on substituted ammonium and phosphonium perchlorates
The investigations described in this thesis have been aimed at contributing to the understanding of the thermal decomposition characteristics of some of the substituted ammonium and phosphonium perchlorates. The importance ... -
Electron diffraction studies of electro-deposits
The work described in this thesis has been directed towards the design and fabrication of an electron diffraction camera, and its use to study the dependence of the structure of electrodeposits upon electrochemical conditions ... -
Heterolytic Activation of the H-X (X=H,Si,B, and C) Bonds inSmall Molecules
The protonation reaction of trans-[Ru(H)(P(OMe)?)(dppe)?][OTf] 2.2 with HOTf led to the formation of 3 new dihydrogen complexes trans-[Ru(?²?H?)(P(OMe)???(OH)?)(dppe)?] (x = 0, 1, 2) which are characterized by their short ... -
Heterolytic activation of molecular hydrogen by transition metal complexes
New iron hydride complexes of the type trans-[(dppe)?Fe(H)(RCN)][BF?] (RCN = nitrile) with varying degree of ?-accepting ability of the nitrile moiety have been prepared and characterized. The protonation reactions of these ... -
Analysis and extraction of molecular hyperpolarizability from on and off resonance hyper-Rayleigh scattering measurements in solution : Ferrocenyl donor-organic acceptor and -(P=N)- linkage based donor acceptor molecules as case studies
Knowledge of accurate second?order nonlinearity or first hyperpolarizability (?) of organic and organometallic molecules is important in a variety of applications. The second?order response from a molecule in solution is ... -
Dynamics of I*(2p1/2) production in the UV photodissociationof alkyl iodides
The photodissociation dynamics of alkyl iodides in their A?band of absorption (arising from n ? ?* transition) has been of interest for dynamicists for the past three decades, starting from the pioneering work of Kasper ... -
Studies in the electro deposition of manganese
The investigations described in the thesis have been directed towards an understanding of the mechanism of electrodeposition of manganese from manganese sulphate–ammonium sulphate solutions and towards an elucidation of ... -
Aspects of the chemistry of copper(II) complexes having different nuclearity
Synopsis of the thesis entitled “Aspects of the chemistry of copper(II) complexes having different nuclearity” to be submitted by Mrs. K. Geetha under the supervision of Prof. A. R. Chakravarty of the Department of Inorganic ... -
Studies on the synthesis, structure and reactivity of amino and halo silanes
Tri(amino)silanes are generally prepared by the condensation route: HSiCl? + 6 R?NH ? HSi(NR?)? + 3 R?NH·HCl Even though these compounds have been extensively used both in industry and chemistry, only very little is known ... -
Electrochemistry at complex interfacial geometries
A study of electrochemical response of interfaces, when one or more of the electrodes assume arbitrary or rough (random) geometries, is of utmost importance but is difficult to analyse. The importance arises from the fact ... -
Magnetism and exchange in the layered transition metal thiophosphates and their solid solutions
It was mentioned in the Introductory Chapter that changes in the magnetic behaviour of the intercalation compounds of the transition metal thiophosphates depend crucially on the magnetism of the host lattice. Hence an ... -

Abstract not available -
Electrode kinetics of hydrogen evoluion reaction & electrodeposition of silver, palladium & silver-palladium alloys.
It has been demonstrated that chemically modified manganese dioxide can be prepared by oxidation of appropriate mixed salt solutions by chlorate ion. Manganese dioxide–coated titanium electrode has been found to be ...
