In a world where gender disparities persist across various realms, this study delves into the ways in which communication can serve as a catalyst for dismantling oppressive norms, amplifying women’s voices, and propelling them towards empowerment. The article critically reviews existing literature on the multifaceted dimensions of women’s empowerment, considering economic, political, social, and personal aspects. It emphasizes the significance of communication as both a tool and an outcome of empowerment, highlighting how access to information and the ability to communicate effectively can shape women’s aspirations, decision-making, and participation in public and private spheres. Drawing on theoretical frameworks such as feminist communication theory, social identity theory, and empowerment theory, the paper dissects the mechanisms through which communication perpetuates or challenges power dynamics. It investigates how media representations, language use, digital platforms, and interpersonal interactions can either reinforce traditional gender roles or facilitate the redefinition of gender norms. Moreover, the article examines case studies from diverse cultural and geographical contexts to illustrate the real-world impact of communication on women’s empowerment. It discusses successful initiatives, campaigns, and policies that leverage communication strategies to enhance women’s agency, leadership, and economic autonomy. Additionally, it addresses the challenges and barriers that persist, including digital divides, online harassment, and the need for culturally sensitive communication approaches. In conclusion, this study underscores the need or a holistic approach to women’s empowerment that integrates communication as a central pillar. By recognizing communication’s role in shaping perceptions, disseminating knowledge, and fostering collective action, stakeholders across academia, policy, and civil society can contribute to dismantling gender inequalities and advancing women’s rights. Ultimately, the article advocates for a transformative and inclusive communication framework that empowers women to shape their own narratives, participate meaningfully in decision-making processes, and forge a more equitable future. 2024-01-01T00:00:00Z http://localhost:80/xmlui/handle/123456789/372 Title: Exploring anisotropic phases and spin transport in perovskite heterostructures: Insights into 3d/5d interfaces for antiferromagnetic spintronics Authors: Sardar, Suman Abstract: Transition metal oxides (TMOs) demonstrate a broad spectrum of properties encompassing electronic correlations, anisotropic transport, magnetism, and optical behavior. The anisotropy arises from both intrinsic crystal symmetry and extrinsic factors like epitaxial strain and structural asymmetry at TMO interfaces. Weiss and Neel's work has elucidated anisotropic magnetic behavior in antiferromagnetic (AFM) materials. AFM TMOs exhibit unique magnetotransport behavior, including weak antilocalization (WAL) and anisotropic magnetoresistance (AMR). Understanding the magnetic structure and band topology in AFM perovskites and their interfaces enables the tailored design of materials for spintronics and energy conversion. In few interfaces lacking inversion symmetry, Rashba spin–orbit coupling (SOC) induces WAL, a quantum correction in conductivity in a two-dimensional electronic system. Electron accumulation and charge transfer across 3d, 5d transition metal-based perovskite interfaces affect WAL and AMR, as observed in 3d/3d and 3d/5d AFM heterostructures, respectively. Advancements in spintronics rely on exploring spin-dependent transport anisotropy. This review focuses on various scattering mechanisms, categorized as extrinsic and intrinsic, in anisotropic transport, particularly in 3d/5d AFM superlattices. The WAL scattering mechanism depends on both intrinsic factors related to Rashba SOC-induced band topology and extrinsic sources like spin impurities and lattice ions. Moreover, the investigation into AMR mechanisms involves the application of impurity-based extrinsic scattering models, which are aligned with the Rashba and Dresselhauss models on Fermi surfaces. This exploration specifically targets the interface of two-band insulators, exemplified by LaAlO3/SrTiO3 and LaVO3/KTaO3. Furthermore, this model achieves comprehensive coverage, extending its applicability to 3d/5d AFM heterostructures like LaMnO3/SrIrO3 and CaMnO3/CaIrO3. Additionally, the intrinsic scattering mechanism tied to Berry phase effects related to band topology is studied, focusing on the CaMnO3/CaIrO3 superlattice. Despite manipulation challenges stemming from reduced stray fields, AFM materials show potential in interface physics and applications within the realm of spintronics. 2024-02-29T00:00:00Z http://localhost:80/xmlui/handle/123456789/370 Title: puruṣārthānām utsa-nirūpaṇam Authors: Jana, Baneswar Abstract: प्राणिभि : परिपूर््णमिदं जगत् ।तत्र तेषु मनुष्य: श्रेष्ठ:। परमब्रह्मणा विनिर्मिते अस्मिन् विश्वे मनुष्याणां भिन्नत्वस्य कारणमपि भगवता निर््धधारितम्। पुरुषार््थ: खलु वुद्धि मतां मनुष्याणां भिन्नत्वकारणम्। अयं पुरुषार््थश्चतुर्विध: धर््ममार््थकाममोक्षभेदेन। तत्र धर््म: खलु धारक:। जगत: धारक:। वस्तुत : धर्मो नियमस्य नामान्तरमेव। अर््थपदेन जागतिकविषया बोध्यन्ते। जगत: यानि कान्यपि प्रयोजनसाधकानि, तान्यर््थपदवाच्यानि। प्रवृत्तिमूलकपुरुषार््थ: काम:। कामवशादेव जगन्निर््ममाणम्। एवञ्चान्तिमे एतेषां त्रयाणां य: फलभूत:, स खलु परमपुरुषार््थ: मोक्ष:। परन्तु कुत्रा यं पुरुषार््थ: निहितोऽस्ति ? वेदादीनि शास्त्राणि पुरुषार््थथानामुत्सस्वरूपाणि। वेदे यद्यपि पुरुषार््थथानां बीजं निहितमासीत्, परन्तु तस्य बीजस्य. 2023-01-01T00:00:00Z http://localhost:80/xmlui/handle/123456789/368 Title: Designed and synthesized de novo ANTPABA-PDI nanomaterial as an acceptor in inverted solar cell at ambient atmosphere Authors: Bagui, Anirban Abstract: In this work, a novel soluble and air-stable electron acceptor containing perylenediimide moiety named ANTPABA-PDI was designed and synthesized with band gap 1.78eV and that was used as non-fullerene acceptor material. ANTPABA-PDI possess not only good solubility but also much lower LUMO (lowest unoccupied molecular orbital) energy level. Furthermore, its excellent electron acceptor capability also supported by density functional theory calculation which validates the experimental observations. Inverted organic solar cell has been fabricated using ANTPABA-PDI along with P3HT as standard donor material in ambient atmosphere. The device, after characterization in open air, exhibited a power conversion efficiency of 1.70%. This is the first ever PDI based organic solar cell that has been fabricated completely in ambient atmosphere. The characterizations of the device have also been performed in ambient atmosphere. This kind of stable organic material can easily be used in fabricating organic solar cell and therefore it can be used as the best alternative as non-fullerene acceptor materials. 2023-09-01T00:00:00Z
