Green Synthesis of Multifunctional Carbon Nanodots from Phyla Nodiflora Leaves Extract and their Potential Applications A. Mushira Banu, S. Jayathivya, B. Arifa farzana, M. Kathiravan Journal of Environmental Nanotechnology, 2025 This study focuses on the synthesis and characterization of carbon nanodots derived from Phyla nodiflora leaves, a naturally abundant and sustainable precursor. Phyla nodiflora leaves due to their rich content of bioactive compounds, such as polyphenols, flavonoids, triterpenes, and saponins. Carbon Nanodots (CNDs) exhibited strong blue-green fluorescence, high quantum yield, and excellent photostability, making them suitable for multifunctional applications. In this research work, CNDs were synthesized from Phyla nodiflora leaf extract using a one-step hydrothermal method to produce highly fluorescent CNDs with remarkable physicochemical properties1.Comprehensive characterization techniques, including UV, Fourier-transform infrared spectroscopy (FT-IR), and fluorescence studies, revealed the surface functional groups and heteroatom doping of the CNDs. The presence of oxygen- and nitrogen-containing groups, naturally doped into the CNDs during synthesis, was attributed to the phytochemical composition of Phyla nodiflora leaves, enhancing their optical and catalytic properties. This study explores the advanced synthesis using a hydrothermal approach and application of PN-CNDs' as a corrosion inhibitor for mild steel in a 1.0 M HCl solution. PN-CNDs were found to be effective in improving corrosion resistance, as evidenced by electrochemical measurements showing a significant increase in polarization resistance and a decrease in corrosion current density. By tackling corrosion-related issues in a range of industrial applications, our research aids in the development of sustainable materials for corrosion protection. The equilibrium data were analyzed using the Langmuir isotherm model to determine the adsorption capacity and surface heterogeneity. Furthermore, structural evaluations using scanning electron microscopy (SEM) validated PN-CNDs-C's dependability as a corrosion barrier.

Syed Ali Padusha, A. Mushira Banu, Swastika Maitra, Hanan M. Alharbi, Vinoth Kumarasamy, Daniel E. Uti, Popat Mohite, Athanasios Alexiou, Iftikhar Ali BMC Chemistry, 2024 The pursuit of advanced multifunctional compounds has gained significant momentum in recent scientific endeavours. This study is dedicated to elucidating the synthesis, rigorous characterization, and multifaceted applications—encompassing anti-corrosion, antimicrobial, and antioxidant properties—of Diethyl 4-(5-bromo-1H-indol-3-yl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate. The 1,4-dihydropyridine derivative was meticulously synthesized through a strategic reaction of ethyl acetoacetate, ammonium acetate, and 5-bromoindole-3-carboxaldehydein the ethanol medium at 60 C. Subsequent spectral validations were conducted using sophisticated techniques, namely FTIR, NMR, and Mass spectrometry, resulting in data that perfectly resonated with the hypothesized chemical structure of the compound. Its anti-corrosive potential was assessed on mild steel subjected to an aggressive acidic environment, employing comprehensive methodologies like gravimetric analysis, Tafel polarization, and EIS. Concurrently, its antimicrobial prowess was ascertained against a spectrum of bacterial and fungal pathogens viz., Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas, Candida albicansandAspergillusniger, leveraging the disc diffusion method and using Gentamicin as a reference standard.The empirical results illustrated a substantial decrement in corrosion rates with ascending concentrations of the organic compound, achieving an apex of anti-corrosive efficacy at 81.89% for a concentration of 2 × 103 M. Furthermore, the compound outperformed Gentamicin in antimicrobial screenings, manifesting superior efficacy against all tested pathogens. The antioxidant potential, quantified using the DPPH free radical scavenging assay against ascorbic acid as a benchmark, was found to have an IC50 value of 113.964 ± 0.076 µg/ml.This comprehensive investigation accentuates the paramount potential of the synthesized dihydropyridine derivative in diverse domains—from industrial applications as a corrosion inhibitor to therapeutic avenues given its pronounced antimicrobial and antioxidant capabilities. The compelling results obtained pave the way for expansive research and development initiatives cantered around this multifaceted compound. Graphical Abstract
Microwave-assisted synthesis of carbon nanodots from Bombax ceiba leaves for enhanced Tribo-corrosion resistance: An experimental and computational analysis A. Mushira Banu, B. Arifa Farzana, N.

Riaz Ahamed, Ashish Kumar Results in Surfaces and Interfaces, 2024 This study presents a novel method for synthesizing carbon nanodots (BC-CNDs) from Bombax ceiba leaf extract via microwave assistance, yielding cost-effective, biodegradable, and water-soluble nanomaterials. Spectroscopic analysis, including FT-IR, UV–Vis, and fluorescence emission spectrophotometry, revealed the distinctive characteristics of BC-CNDs. Additionally, an anti-corrosive coating (BC-CNDs-C) was formulated by blending BC-CNDs with a plasticizer and binder. Quantitative evaluation of BC-CNDs-C showed an impressive inhibitory rate of 92.55% against corrosion. Electrochemical measurements indicated a notable increase in polarization resistance (R p values: 1782.2 Ω cm 2 for P1 to 4778.3 Ω cm 2 for P4) and a decrease in corrosion current density (I corr values: 0.065 μA/cm 2 for P1 to 0.010 μA/cm 2 for P4) with the incorporation of BC-CNDs, highlighting their effectiveness in enhancing corrosion resistance. Additionally, structural analyses via scanning electron microscopy (SEM) and atomic force microscopy (AFM) confirmed the reliability of BC-CNDs-C as a corrosion barrier. This research contributes to the development of sustainable materials for corrosion protection, addressing corrosion-related challenges in various industrial applications. • Novel microwave-assisted synthesis of eco-friendly carbon nanodots. • BC-CNDs show impressive 92.55% corrosion inhibition rate. • Enhanced corrosion resistance with BC-CNDs in anti-corrosive coating. • Structural analysis confirms BC-CNDs-C as reliable corrosion barrier. • Sustainable solution for corrosion protection in diverse industries.
The Role of Inorganic Nanomaterials in Energy Storage Devices A. Mushira Banu, B. Arifa Farzana, F.M. Mashood Ahamed Multifunctional Inorganic Nanomaterials for Energy Applications, 2024 Energy storage devices, particularly supercapacitors (SCs) and batteries, are the principal chemical-based modern sources that are widely used in our day-to-day life, such as in the early stages of autos and children’s toys. Nevertheless, given that everything is dependent on energy, the rising demand for these gadgets is alarming. Researchers are always looking for alternatives to fossil fuels, such as electrochemical super capacitors, fuel cells, and batteries, to avoid these issues. There has been a lot of interest in creating effective materials for energy storage applications, particularly for supercapacitors and batteries, which are the most promising and significant power sources used in daily life. Nevertheless, the SC’s performance is influenced by the electrode, or active material, as well as the current collector’s behavior, which includes electrical conductivity, surface area, porosity, electrochemical activity, and morphological geometries. To achieve extremely efficient energy use, our society has been up against growingly difficult obstacles. Multifunctional nanomaterials have been gaining popularity in the area of energy applications. The electrical, thermal, mechanical, optical, and catalytic properties of materials are crucial for a variety of energy applications, including energy generation, conversion, storage, savings, and transmission. Thermoelectric, piezoelectric, triboelectric, photovoltaic, catalytic, and electrochromic materials have significantly impacted a variety of energy applications at the nanoscale level due to their distinctive qualities, such as electrical, thermal conductivity, a large surface area, and chemical stability. Inorganic nanoparticles are extremely competitive in the energy sector. The most recent studies and developments of multifunctional inorganic nanomaterials for energy applications were compiled in this study from the standpoint of various energy applications. In order to enhance their performances and the incorporation of nanomaterials’ individual functions into a device, researchers demonstrated the special functionalities of inorganic nanomaterials. The restrictions imposed by scaling the relationships between multifunctional inorganic nanomaterials and energy devices, however, can be blamed for the difficulties.
