Pondicherry University, also known as PU, is a collegiate public central university located in Kalapet, Pondicherry, Union Territory of Puducherry, India. It was established by an Act of Parliament in 1985 by the Department of Higher Education, Ministry of Education, Government of India. The Vice President of India is the Chancellor along with the Lieutenant Governor of Puducherry acting as the Chief Rector and the President of India is the Visitor of the University. The university is a collegiate university with its jurisdiction spread over the Union Territory of Puducherry located in Tamil Nadu (Pondicherry and Karaikal), Kerala (Mahé) and Andhra Pradesh (Yanam), and Union Territory of Andaman and Nicobar Islands. The vast jurisdiction over three Union Territories namely gives the University a national character. The residents speak diverse languages such as English, Tamil, French, Telugu, Malayalam, Hindi, Bengali, Oriya and Kannada.Local skill sets are advanced through several vocational programs such as paramedical courses using the on-site hospital facilities.
This study examines 120 research papers on cryptocurrency adoption, investment, and investor behavior using preferred reporting items for systematic reviews and meta-analyses–guided systematic literature review. Further, it intends to illustrate the key trends, institutions, and country contributions to this field through a bibliometric analysis. The findings indicate that people’s decision to adopt cryptocurrencies is primarily facilitated by social factors and hindered by fluctuations, ease of buying cryptocurrencies, and jurisdictional issues. It also reveals an impact of psychology, which erupts in the forms of herding and instrumental sentiments. A conceptual framework of cryptocurrency adoption and investment intensity in fintech ecosystem is proposed. The study provides fresh insights into investment intensity, fintech-motivated investment trends, and investor behavior in cryptocurrency.
Understanding tree community composition is central to monitoring biodiversity patterns, and recent advances in Earth observation (EO) offer powerful means to study these dynamics across large landscapes. In this study, we present an approach for classifying of tree communities by combining field-based information with machine learning that incorporates environmental factors and remote sensing data, including multi-temporal imagery and their derivatives. By leveraging EO data, five different scenarios with a combination of different EO variables were constructed and tested for their performance in accurately mapping 13 tree communities using a Random Forest classification approach. The evaluation results demonstrated that the utilisation of integrated EO data in scenario 5 yielded notably enhanced performance in accurately classifying tree communities with an overall accuracy of 83 Field and Earth observation data with spatial models used for tree community mapping. The map accuracy achieved 83
Doping serves as a versatile strategy to modify the chemical, physical, electrical, and optical characteristics of materials, making them highly suitable for energy storage applications. This work investigates the enhancement of electrochemical performance in hausmannite Mn3O4 nanoparticles (NPs) through doping with cerium (Ce) ions. Ce-doped Mn3O4 NPs were synthesized using a non-thermal microplasma discharge technique applied to a precursor solution containing KMnO4 and Ce(NO3)(3) & centerdot; 6H(2)O. The solution underwent air microplasma treatment for 30 mins at a discharge power of 40 W, achieving effective doping over the range of 0.5%-3.0%. Electrochemical testing performed in a standard three electrode configuration within a 1 M KCl electrolyte revealed notable improvements in energy storage performance. Specifically, 2% Ce doping resulted in a maximum specific capacitance of 234 Fg(-1) at 0.5 Ag-1. This enhancement is linked to Ce induced modifications in lattice structure and particle morphology, which favour pseudocapacitive behaviour and facilitate charge transfer. Moreover, the doped NPs showed excellent cyclic stability, retaining 86% of their capacitance and achieving 90% Coulombic efficiency after 5000 cycles at 4 Ag-1. These results demonstrate that Ce doped Mn3O4 NPs are promising pseudocapacitive materials for advanced supercapacitor applications.
The current study employed the enzyme-assisted extraction for the bioconversion of Ulva rigida and isolating the ulvan polysaccharide. The extracted ulvan was characterized using Fourier transform infrared spectroscopy, x-ray diffraction, electrospray ionization-mass spectrometry, and differential scanning calorimetry analysis. The antioxidant activity (scavenging of DPPH free radical and reducing power assays), antibacterial activity (against four food pathogenic bacteria), prebiotic activity, water- and oil-holding capacities, and emulsifying and foaming properties of the isolated ulvan were investigated. The ulvan yield from U. rigida by the enzyme method was 37.8%. The extracted ulvan possesses 92.64% DPPH scavenging and 0.2515 Abs, reducing power activities at a concentration of 4 mg/mL. Antibacterial studies revealed that the isolated ulvan exerted antibacterial activity against Escherichia coli and Listeria monocytogenes with 5- and 4-mm semidiameter inhibition zones at 10 mg/mL concentrations, respectively. However, it was not active against Staphylococcus aureus and Salmonella enterica. The growth of Bifidobacterium bifidum, Lactobacillus acidophilus, and Lactobacillus plantarum bacteria was increased in the presence of the extracted ulvan, which indicates its prebiotic activity. The water-holding capacity of the extracted ulvan (6.18 g water/g sample) was higher than its oil-holding capacity (0.5 g oil/g sample). The results also demonstrated that the extracted ulvan could emulsify the corn, sunflower, and canola oils. The foaming capacity and stability of the extracted ulvan were 14.08% and 4.30%, respectively. These results suggested that the enzyme method recovered ulvan from U. rigida with different bioactivities and technofunctional properties, making it suitable for application in various food and cosmetic products as a nutraceutical and natural preservative.
