Title: Harnessing the potential of sulfamidyl radical in photocatalytic synthesis of organosilanes and organogermanes Authors: Bajya, Kalu Ram Abstract: The focus of this thesis is to harness the potential of sulfamidyl radical for the functionalization of Si-H/Ge-H bonds of hydrosilanes/hydrogermanes through hydrogen atom transfer for the photocatalytic synthesis of organosilicon and organogermanium compounds. Firstly, the sulfamidyl radical was generated under visible light-assisted photocatalytic reductive quenching condition by using simple sulfonamide as a precursor for sulfamidyl radical and achieved selective functionalization of Si-H/Ge-H bond over C-H bond of hydrosilanes/hydrogermanes. Moreover, sulfonamides are readily accessible from inexpensive and commercially available sulfonyl chlorides and amines, rendering them cost-effective HAT catalyst. The steric and electronic properties of sulfonamide can be systematically tuned, enabling optimal matching with the varying bond dissociation energies of the Si-H and Ge-H bond of hydrosilanes and hydrogermanes respectively. In addition, a complementary protocol was also developed for the generation of sulfamidyl radical under photocatalytic oxidative quenching condition using N-aminopyridinium salt, enabling the synthesis of organosilicon and organogermanium compounds.

Title: Reimagining public spaces through city literature of Delhi: mapping the history, present concerns and future transformations Authors: Bala, Apsara Abstract: The ongoing debate surrounding public spaces revolves around several key issues: their historical existence, the meaning attributed to them, the varying expectations from different communities regarding how they perceive these spaces, the influence of material structures on the creation of the public sphere, and the contentious nature of the term ‘public,’ especially given the evidence of various forms of exclusion. Questions arising in this area highlight the compromises, conflicts, and contestations that characterise public space’s inherently ambiguous and fluid nature. Although there are various theories and histories (Arendt 1958; Lefevre 1991; Sennett 1992; Mitchell 1995, 2003) regarding public space and accessibility, our exploration revealed a significant gap in the thorough analysis and reimagining of public spaces within the Indian context. Consequently, this thesis analyses the transformation of public spaces through an architectural lens in urban literature and applies the literary urban studies (Daniel and Queiroz 2013; Gurr 2021; Jason 2022) framework in the analysis. Here, we are more focused on critiquing the aspects of growing privatisation efforts (Boycko 1996) and the top-down approach in urban planning, which displays the postcolonial urbanism (Kalyan 2017; Grubbauer 2019; Myers 2020) aspect of our thesis.

Title: Dynamics of an interacting hadron gas and measurements of Υ(nS) production and polarization in proton-proton collisions at √s = 13.6 TeV with ALICE Authors: Pradhan, Kshitish Kumar Abstract: Ultra-relativistic heavy-ion collision programs at the Large Hadron Collider (LHC) at CERN and the Relativistic Heavy Ion Collider (RHIC) at BNL are designed to explore strongly interacting matter under extreme conditions of temperature and energy density. In these experiments, the so-called little Bang created in ultra-relativistic nuclear collisions leads to the formation of a novel state of matter known as the quark–gluon plasma (QGP), in which quarks and gluons are no longer confined within hadrons. This state of matter is believed to have existed during the first few microseconds after the Big Bang. Consequently, studying the properties of QGP not only deepens our understanding of the strong interaction at the microscopic level but also provides valuable insight into the early evolution of the universe. The short lifetime of the QGP matter does not leave any direct signature. Its properties are inferred through indirect signatures and through a detailed understanding of the system’s evolution across different stages of the space-time evolution of the created fireball. The transport properties can play a major role in characterizing the dynamical evolution of the produced medium. Since the transport coefficients can, in principle, be derived from fundamental theory, their variation with thermodynamic parameters such as temperature and chemical potential can be useful in identifying the phase structure of QCD.
