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 ... -
Studies on substituted LnBa2Cu3O7-d (Ln=Y or Rare-Earth) : synthesis, structure, microstructure, and properties of bulk materials and thin films
The most commonly employed solid-state reaction method for the synthesis of YBa?Cu?O??? ceramic has been improved upon. The shift in the incongruent melting of YBa?Cu?O??? to a higher temperature in an oxygen atmosphere ... -
Studies on pressed and roll-compacted alkaline iron-electrodes for nickel-iron secondary cells
It is concluded that various sulfide additives employed in this study retard passivation of the iron electrode during discharge and suppress the rate of the HER during charging. The electrodes doped with Bi?S? show minimum ... -
Synthesis, structure and properties of inorganic-organic hybrid compounds
Synthesis, structure, photodimerization, structural transformation and photocatalytic studies have been carried out on a family of cadmium thiosulfate compounds with varying dimensionalities. The observation of unique Cd?S? ... -
Electron spectroscopic investigations of nitrogen adsorbed on transition metal surfaces and of oxide superconductors.
1.4 Conclusions The core and valence level binding energies and vibrational stretching frequencies of nitrogen adsorbed on clean as well as modified transition?metal surfaces are summarized in Tables I.1–I.3. From Table ... -
Nanocrystals and nanocrystalline films of metal oxides and related materials
Certain observations and conclusions regarding the investigations presented in Chapters 5 to 9 are described here. The analysis is in relation to the ‘SCOPE OF THE WORK’ indicated in Chapter 1. The present work is mainly ... -
X-ray spectroscopic and magnetic....systems
The thesis is primarily based on detailed studies of transition metal oxide systems employing X?ray absorption spectroscopy, X?ray photoelectron spectroscopy and magnetic susceptibility measurements. Chapter I deals with ... -
Studies on the vapour-phases oxidation of somealcohols in a fixed, bed reactor
Mechanism of the vapour?phase oxidation of alcohols over ferric molybdate catalyst was investigated in a fixed?bed isothermal differential flow reactor. Ring?substituted 1?phenylethanols were used as the organic substrates ... -
Synthetic investigations in steroids: a new approach to the total synthesis of estrone and its analogues.
The object of the present investigation is to develop a new strategy for the synthesis of aromatic steroids and their analogues. The thesis entitled “SYNTHETIC INVESTIGATIONS IN STEROIDS: A NEW APPROACH TO THE TOTAL SYNTHESIS ... -
