Kavayitri Bahinabai Chaudhari North Maharashtra University is a university situated in Jalgaon, Maharashtra. Formerly North Maharashtra University was established on 15 August 1990 after separating it from the parent University of Pune.In 2001, NAAC accredited the prestigious 4-Star Status to the university. The university was re-accredited by NAAC as 'B'(CGPA 2.88 on 4 point scale) grade university. Currently during the third cycle re-accreditation by NAAC, the university has been awarded with 'A' grade (CGPA 3.
A one-pot telescopic approach has been developed for the safe, scalable, and efficient synthesis of substituted 2-arylimidazo[1,2-a]pyridines starting from commercially available and inexpensive substituted acetophenones and 2-aminopyridine. The procedure involves the in situ formation of phenacyl bromides via chemoselective bromination of acetophenones with N-bromosuccinimide, followed by nucleophilic substitution and heterocyclization with 2-aminopyridine to yield 2-arylimidazo[1,2-a]pyridines. This streamlined telescopic method avoids handling and isolation of hazardous and lachrymatory phenacyl bromides. Moreover, this synthetic protocol eliminates unit operations such as solvent extraction, solvent evaporation/distillation, and final product purification. Notably, the practical utility of this telescopic approach has been demonstrated on a gram scale, affording the product in good yields.
A novel azo dye-based Schiff base receptors 1 and 2 were designed and synthesized via a sequence of steps and characterized by 1H NMR and single crystal X-ray crystallography. The cation recognition properties of receptor 2 were systematically investigated using fluorescence spectroscopy. Notably, receptor 2 displayed a distinct "turn-off" fluorescence response that was highly selective towards Fe3+ ions, with no significant interference from other tested cations. The binding studies revealed a detection limit as low as 2.5 mu M, demonstrating the high sensitivity of receptor 2. Furthermore, the practical applicability of receptor 2 was validated by successfully determining Fe3+ levels in a pharmaceutical drug sample. These findings highlight the design synthesis of new receptor 2 as a promising, cost-effective fluorescent receptor for the selective detection of Fe3+ ions.
Mixed halide perovskite films are important for various optoelectronic applications. This study involves the synthesis and characterization of mixed halide perovskite films MAPbBrxI3-x (where x = 0, 1, 2, 3), by maintaining a fixed 1:1 molar ratio of the methylammonium halide and lead halide in spin coating. The films were fabricated via the spin coating method on glass substrates. UV–visible absorption spectroscopy revealed a tunable optical bandgap ranging from 1.57 (MAPbI3) to 2.27 eV (MAPbBr3), corresponding to absorption edges that shifted from 788 to 547 nm as the bromine content increased. X-ray diffraction confirmed high crystallinity, particularly in MAPbBr2I, which exhibited the most intense and sharp peaks. SEM analysis revealed varied morphologies influenced by the halide composition, with the fixed equimolar ratio resulting in well-defined and uniform crystal structures. Notably, MAPbBr2I displayed a smooth and uniform surface, indicating superior film quality and minimized defect density. FTIR and Raman spectroscopy provided insights into molecular interactions, vibrational modes, and structural properties. This study uniquely highlights how maintaining a consistent organic-to-inorganic ratio influences the optical, structural, and morphological properties of mixed halide perovskites. The findings suggest that MAPbBr2I, with its optimal crystallinity, bandgap, and morphology, is a promising candidate for optoelectronic applications.
Artificial Intelligence (AI) has emerged as a transformative force in the global economy, significantly influencing production systems, governance mechanisms, and social structures. In the Indian context, the evolution of AI forms an important part of the country’s post-independence journey towards modernization and digital transformation. Although India’s engagement with advanced technologies began gradually after independence in 1947, the rapid growth of digital infrastructure, data availability, and policy initiatives in the late twentieth and early twenty-first centuries has accelerated AI adoption across sectors. This research paper examines the role of Artificial Intelligence in shaping India’s digital economy after independence, with a focus on its major achievements, persistent challenges, and future prospects. The study is based entirely on secondary data collected from government reports, policy documents, research articles, and institutional publications. The findings indicate that AI has contributed significantly to economic efficiency, service delivery, innovation, and global competitiveness. However, issues such as data privacy, skill gaps, digital divide, ethical concerns, and regulatory limitations continue to pose challenges. The paper concludes by emphasizing the need for inclusive policies, skill development, ethical governance, and sustainable AI deployment to strengthen India’s digital economy in the years ahead.
Rural communities in developing economies often face financial vulnerability due to irregular income, limited access to formal financial services, and high exposure to life risks. Life insurance, when designed appropriately, can act as a critical tool for financial security, poverty reduction, and long-term rural development. This study examines the role of life insurance products tailored for rural populations, explores key challenges in adoption, analyses existing models, and proposes strategic innovations to enhance insurance penetration. Using a mixed-method research design—including literature review, policy analysis, and case studies from India, Bangladesh, Kenya, and micro-insurance models—the paper highlights how inclusive insurance products can improve household resilience, support entrepreneurship, and promote sustainable rural development. The findings suggest that simplified products, technology-driven distribution, community-based channels, flexible premium structures, and strong government support significantly increase uptake and impact. The paper concludes with policy recommendations and a framework for designing scalable, affordable rural life insurance solutions.
