Kinetic and synthetic investigation of the reactions os halogeno and arlyosycyclophosphazenes
The reaction of hexafluorocyclotriphosphazene, N?P?F? (14), with sodium phenoxide in THF yields phenoxy?substituted fluorocyclotriphosphazenes of all degrees of substitution. The results obtained in this investigation ... -
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 ... -
Kinetics and mechanism of the transient behaviour of magnesium anodes
The main objective of the present investigation is to study the mechanism of delayed dissolution of magnesium anodes during discharge of magnesium dry cells. A supplementary part of the work is devoted to the development ... -
Lanthanide and actinide complexes of diphosphazane dioxides and lanthanide complexes of amino acids and peptides
The chemistry of f-block elements is currently undergoing rapid developments, and a rich and diverse chemistry is emerging because of its various applications (e.g., MOCVD precursors, MRI contrast agents). In addition, ... -
Low temperature synthesis & characterization of fine particle perovskite oxide & structurally rlated mixed metal oxides
This thesis concentrates on the precursor chemistry of simple and mixed metal carboxylates, especially the citrates and tartrates. The carboxylate process is simple, convenient and most efficient to synthesize fine powders ... -
Low-Symmetric Water-Soluble Molecular Hosts for Molecular Separation and Optical Modulation
Nature employs the strategy of self-assembly in a remarkable way at every scale to construct numerous functional architectures. Various noncovalent interactions, such as hydrogen bonding, 𝜋-𝜋 stacking, and electrostatic ... -
Low-temperature preparatioin and characterization of the perovskite lanthanide chromites and related oxides
The thermal decomposition of lanthanum biscitrato chromate(III) dihydrate was investigated in both static air and flowing argon atmospheres. The complex decomposes in four distinct steps, forming oxycarbonate and ... -
Magnetic and spectroscopic investigations of iron and other ..... Ligands
The complexes of a new ligand, 2-thioacetamido thiazole (TATZ) with halide and nitrate salts of Fe(II), Ni(II), Cu(I,II), Zn(II), Cd(II) and Hg(II) have been synthesized. The compounds have the general formula, M(TATZ)?·nH?O ... -
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 ... -
Many-body effects in electrochemisorption and electron transfer processes
Two important phenomena that govern the behaviour of an electrochemical interface are (a) chemisorption and (b) electron transfer. The combination of these — electron transfer involving chemisorbed entities — is also of ... -
Mapping The Reaction Coordinate For The Oxidative Addition Of Molecular Hydrogen To A Metal Center
(2010-07-15)The binding of molecular hydrogen to a metal center leads to the elongation of the H−H bond and subsequently to its cleavage along the reaction coordinate for the oxidative addition of H2. There has been considerable ... -
Materials For Hydrogen Generation, Storage, And Catalysis
(2013-01-22)Hydrogen, nature’s simple and the most abundant element has been in the limelight for the past few decades from the stand point of the so-called hydrogen economy. With a high calorific value (142 MJ/kg) that is three times ... -
Measurement Of Dissociation Constant (Ka) And Partition Coefficient (KP) Of Weak Organic Acids From Their First Hyperpolarizabilities
(2012-05-30)Weak organic acids and their salts are slowly becoming recognized as an important class of materials for second-order nonlinear optics (NLO) due to their high second harmonic generation (SHG). The main advantages in using ... -
Mechanism of electroreduction of nitrobenzene in alkaline media
Nitrobenzene is shown to give a stepwise reduction in certain media. With a view to examine the factors which influence the scheme of reduction, the effect of different solvents and ionic strengths are examined using tast ... -
Mechanistic Insights Into Small Molecule (Amine-Boranes, Hydrogen, Methane, Formic Acid Carbon dioxide) Activation Using Electrophilic Ru(II)-Complexes
(2017-11-09)Current fossil fuels (Coal and Petroleum) based economy is not sustainable in the long run because of its dwindling resources, and increasing concerns of climate change due to excessive carbon dioxide (CO2) emission. To ... -
Mechanistic Investigation and Engineering of a Membrane-Bound Hydrocarbon-Producing Metalloenzyme
The pursuit of sustainable and environmentally friendly fuels, such as biofuels, is gaining attention as an alternative to diminishing fossil fuel resources. Consequently, there is a significant focus on the sustainable ...
