Punyashlok Ahilyadevi Holkar Solapur University is a state university located in Solapur, Maharashtra, India. Formerly it was postgraduate centre of Shivaji University. Punyashlok Ahilyadevi Holkar Solapur University was established on 1 August 2004 and was inaugurated on 3 August 2004 by the Governor of Maharashtra. The formation of the university at Solapur was a long cherished desire of the people of this region. Earlier, to the formation of Punyashlok Ahilyadevi Holkar University, Solapur had a P.G. Centre of for over two decades. The centre for P.G. studies had three postgraduate science departments and 7 postgraduate courses conducted in the P.G. departments. With this sound background has been established to cater the needs of over 60,000 students community. The university is poised for an ambitious growth. The University is now a hub of various academic activities. Good number of Engineering, Agricultural, Architectural, Medical and Traditional institutions of national fame are located in and around the city. Solapur is a home of religious saints of various languages as the district is at a triple junction of linguistic states of Andhra, Karnataka. Therefore, Solapur is secular and metropolitan to its core. The said backdrop makes the University stands for transcendent principles and embodying noble mission. It is a small team yet progressive and forward-looking. Perched on a plateau, the is a citadel of higher learning. Recently the university has introduced the concept of school system and has decided to bring its various departments under umbrella of various schools, viz.
Iron oxide thin films with compact and granular morphology were successfully synthesized at room temperature via the chemical bath deposition (CBD) technique with systematic variation in the molar concentration of ferrous sulfate precursors. The influence of precursor concentration on the structural, morphological, and electrochemical properties was comprehensively investigated. X-ray diffraction (XRD) confirmed the polycrystalline nature of the films, while Fourier-transform infrared (FTIR) spectroscopy verified the formation of Fe–O bonding. Field-emission scanning electron microscopy (FE-SEM) revealed concentration-dependent modifications in the granular morphology, whereas wettability measurements demonstrated the hydrophobic character of the films. Electrochemical evaluation in 1 M NaOH using cyclic voltammetry (CV), chronopotentiometry, and electrochemical impedance spectroscopy highlighted a strong dependence of capacitance behavior on precursor concentration. The optimized electrode achieved a maximum specific capacitance of 244 F g⁻1 at 5 mV s⁻1, alongside superior energy and power densities of 90.35 Wh kg⁻1 and 8.30 kW kg⁻1, respectively, with an efficiency of 98.2
The zinc oxide (ZnO) nanostructures are widely regarded as promising candidates for advanced energy storage systems owing to their outstanding electrochemical behaviour. ZnO nanostructures are fabricated through an eco-conscious bottom-up synthesis route using night jasmine leaf extract as a natural reducing and stabilizing medium. The synthesis is carried out without the use of any additional catalysts, highlighting the green and sustainable nature of the process. The synthesized ZnO nanostructures are systematically characterized by X-ray diffraction to determine the crystalline phase, Fourier transform infrared spectroscopy to identify the surface functional groups, scanning electron microscopy to examine morphological features, and energy-dispersive X-ray spectroscopy to confirm elemental composition. Electrochemical performance is evaluated using cyclic voltammetry in a three-electrode configuration, where the ZnO electrode exhibits pronounced pseudocapacitive behaviour. The night jasmine-derived ZnO coated on a stainless steel substrate delivers a high specific capacitance of 480 F/g at a scan rate of 2 mV/s, while maintaining stable performance during repeated measurements. These results demonstrate that green-synthesized ZnO nanostructures provide a low-cost, sustainable, and efficient pathway for supercapacitor applications.
The digital transformation of academic ecosystems requires systems capable of addressing diverse cognitive behaviors. Traditional models lack personalized pathways, which reduces student engagement. In this chapter per the authors, a comprehensive adaptive framework is proposed to enhance academic outcomes. By integrating predictive analytics, the system dynamically assesses performance, identifies knowledge gaps, and recommends personalized resources. A hybrid approach combining Random Forest for static prediction and Long Short-Term Memory networks for sequential analysis captures structural and temporal data patterns. Experimental evaluations demonstrate significantly improved prediction accuracy, faster dropout risk identification, and higher engagement. This architecture provides a robust, data-driven foundation for developing student-centric environments while democratizing intelligence for scalable institutional deployment.
The present study systematically investigates the influence of sintering temperature on the gas-sensing and photocatalytic performance of pristine WO3 nanostructures synthesized via a facile one-step hydrothermal route. The as-synthesized WO3 powders were sintered at 425, 525, 625, and 725 °C to modulate their structural, morphological, optical, and surface characteristics. Comprehensive characterization using XRD, FE-SEM/EDX, TEM/HRTEM, XPS, UV–Vis spectroscopy and BET surface area analysis confirmed the formation of phase-pure monoclinic WO3 with a well-defined nanoplate-like morphology. Among the investigated samples, WO3 sintered at 525 °C exhibited optimized crystallinity, an enhanced specific surface area, favourable pore characteristics and a higher concentration of surface oxygen species. Gas-sensing measurements demonstrated a maximum response of 85.09
Purpose This study aims to examine the impact of India’s Unified Payments Interface (UPI) on rural financial inclusion and economic growth (2019–2023), focusing on entrepreneurship, household financial behaviour and business formation. It identifies the mechanisms through which UPI adoption drives rural economic transformation. Design/methodology/approach Using a difference-in-differences approach, the study analyses UPI transaction data and household surveys from 200 villages across four Indian states to assess causal effects on financial and economic outcomes. Findings Villages with higher UPI adoption saw a 27% rise in business registrations, a 34% increase in savings accounts and a 42% growth in female-owned enterprises. In comparison, informal borrowing declined by 53% and digital credit access improved by 29%. These effects stemmed from lower transaction costs, better financial information access, network effects driving adoption and increased trust in digital finance. Research limitations/implications The findings are confined to four Indian states – Maharashtra, Karnataka, Uttar Pradesh and Gujarat – and the extrapolation to other regions or emerging economies needs to be taken with caution, observing local economic and institutional conditions. Long-term consequences need to be investigated further. Regional differences, wealth generation and policy reforms applicable to other economies need to be considered in future research. Practical implications Strategic deployment of digital finance, literacy programmes and regulatory safeguards can maximise inclusion and economic impact. UPI adoption also empowers women entrepreneurs, formalises businesses and reduces informal lending dependence, but it requires mitigation of digital exclusion and cybersecurity risks. Originality/value To the best of the authors’ knowledge, this study provides the first causal evidence of UPI’s role in rural economic transformation, introducing a theoretical framework linking digital finance to market integration and financial inclusion.
