The role of antioxidants in enhancing biodiesel oxidation stability: application in maritime decarbonization
Huang Teik Lay, Vibushan Arangaswamy, Sibnath Kayal, Imran Ibrahim, Ming Liu
Biofuels Bioproducts and Biorefining, 2026
From 2030, all new harbor craft operating in the Port of Singapore must be fully electric, or capable of using neat biodiesel, or compatible with net zero fuels such as hydrogen. B100 biodiesel consists of 100% pure biodiesel derived from renewable sources. To ensure its suitability for diesel engines, technical specifications and quality requirements are defined by European standard EN 14214, American standard ASTM D6751, and international standard ISO 8217, which set maximum or minimum limits for relevant parameters. This review examines the impact of antioxidants on biodiesel oxidation stability, considering feedstock selection and antioxidant performance to enhance storage reliability and operational performance in maritime applications. As a drop‐in fuel, biodiesel is susceptible to oxidation during production and storage, potentially causing quality degradation. Optimizing antioxidant selection to improve biodiesel storage stability and operational reliability in maritime applications requires a comprehensive understanding of concentration, polarity (as explained by the polar paradox theory), and molecular mobility (as described by the reduced mobility hypothesis).
Point-of-Care Photoresistive and Colorimetric Sensor for Iron Detection in Environmental and Biological Samples with Spectroscopic Validation
Shrikant Kashyap, Purushotam Shivshakti Mahan, Harendra Singh, Sibnath Kayal, Tapas K. Mandal
Chemistry an Asian Journal, 2025
The development of an innovative, selective, and portable digital photoresistive sensor for sensing iron in the environment and biological samples is reported in this article. Colorimetric sensing of the analyte is investigated, akin to the spectrophotometric absorption principle. Iron in the sample is measured by the formation of orange‐colored ferroin resulting from the 1,10‐phenanthroline reaction. The reaction scheme is designed to be pH‐specific, simple, quick, and effective in detecting trace amounts of iron in real sample matrices without employing any tedious route of synthesis and its characterization. A digital photoresistive prototype is fabricated using a light‐emitting diode (LED) and a light‐dependent resistor (LDR) to measure the concentration of iron much less than the recommended value by the World Health Organization (WHO). The limit of detection (LOD) is reported to be 0.017 mg L−1, the lowest to date for the class of point of care (POC) devices. The sensor was tested on 55 real‐life samples and exhibited good accuracy with UV–vis and AAS measurements with an average absolute % error of 3.258%–14.34%. The present prototype promises to be a user‐friendly, cost‐effective solution to the pressing need of monitoring iron for the environment and healthcare sector.

Canadian Journal of Chemical Engineering, 2024
2D simulations have been performed to investigate flow regimes in a flow‐focusing geometry by changing the dispersed phase and continuous phase velocities. The dispersed phase is polydimethylsiloxane (PDMS), and the continuous phase is water. Simulations have been performed in a range of oil–water viscosity ratio from 3 to 50, and interfacial tension ranges from 0.0118 to 0.002 N/m. The walls of the microchannel are considered to be poly(methyl methacrylate) (PMMA) surfaces. The contact angle (θ) of an oil droplet in the presence of water wetting the PMMA surface is 140°. Our study observed two types of flow regimes, namely dripping and jetting, by changing the dispersed phase and continuous phase velocities. The sequential time steps of void fraction contour have been presented to explore the droplet formation mechanism. The droplet pinch‐off time and jet growth time have been calculated for the dripping and jetting regime, respectively. The outcomes are summarized in the form of a flow pattern map at a viscosity ratio of 12 and interfacial tension of 0.0118 N/m, which shows the transition boundary between dripping and jetting phenomena. The simulated transition boundary agrees well with the analytical solution available in the literature. The effect of oil–water viscosity ratio and interfacial tension on droplet size is also investigated. These findings will help understand different flow regimes and their transition in a flow focusing geometry and will directly apply to microfluidic platform‐based devices.

Analysis of CH4 Adsorption Isotherms onto MIL-101 (Cr) Metal-Organic Framework and Its Derivatives with Alkali Ion Dopants
Ayushi Singh, Sibnath Kayal
Protection of Metals and Physical Chemistry of Surfaces, 2022
In this paper, methane (CH4) adsorption isotherms for metal-organic framework (MOF) adsorbents in the subcritical regions have been reported. Virgin MIL i-101 i-i (Cr) MOF and its derivatives doped with alkali ions, are used to study the impact of alkali dopants on CH4 adsorption isotherms. The CH4 adsorption isotherms have been analyzed by Langmuir, Toth and Dubinin–Astakohv adsorption models to determine the adsorption parameters. It has been observed that the isosteric heat of adsorption diminishes with increasing alkali dopant size, while the induced surface structural heterogeneity increases with increasing alkali dopant size.

Evaluation of optimum condition to improve the microstructure in hot-rolled medium carbon steel by elimination of coarse pearlite patches
Adityakumar Mishra, Sibnath Kayal
Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2022
The present study is aimed to eliminate the undesirable microstructure in the real working condition of the steel unit. In this work, the microstructure of hot-rolled medium carbon steel (grade 45C8) is studied for application in the automotive industry. The effect of the temperature and rolling rate on the microstructure has been thoroughly investigated by analyzing the microstructure containing ferrite and pearlite phases after each trial run of hot-rolled steel. The desired microstructure of fine ferrite and pearlite is very much essential in hot-rolled medium carbon steel for better strength and uniform properties of the material. The formation of coarse pearlite is undesirable, which may lead to breakage during drawing and hardness variation in the hot-rolled steel. Therefore, this study is focused to find the optimum condition for achieving the microstructure containing uniform distribution of fine pearlite and ferrite without the presence of blocky pearlite patches.
Benign Synthesis of Metal-organic Framework (MIL-101-Cr) and Evaluation of Car-bon-dioxide Adsorption Behaviour Employing Adsorption Isotherm Models
Ayushi Singh, Sibnath Kayal
Current Organic Synthesis, 2022
Background: In today’s world, rising temperature due to global warming is caused by higher concentration of carbon dioxide (CO2) emissions in the atmosphere. Metal-Organic Framework (MOF) materials have the potential to be used in carbon dioxide capture and utilization technology. Objective: The purpose of this work is to prepare metal-organic framework materials by a benign synthesis method using water as the solvent, followed by the characterization and property evaluation for CO2 adsorption study. Methods: MIL-101-Cr metal-organic framework and its derivatives with alkali ion dopants were prepared by benign hydrothermal synthesis route, which were characterized by powder X-ray diffraction method. The adsorption isotherms of CO2 for MIL-101-Cr and its derivatives were studied to comprehend the influence of alkali dopants on CO2 sorption behaviour. The equilibrium uptakes of CO2 were further evaluated by fitting the isotherms with Langmuir, Toth and Dubinin – Astakohv adsorption models to determine the adsorption parameters. Results: The crystalline structural integrity of MIL-101-Cr is not affected by doping with alkali ions. The isosteric heat of CO2 adsorption is diminished with an increase in alkali dopant size, while the induced surface structural heterogeneity increases with increasing alkali dopant size. Conclusion: The equilibrium and thermodynamic parameters calculated from this study are useful for applications in carbon dioxide capture and utilization technology.
