Influence of molybdenum on structural, morphological, optical and electrochemical properties of ZnO nanoparticles P. Sakthivel, P. Periasamy, N. Dineshbabu, T. Suthan, N. Chidhambaram, K. Ravichandran Next Materials, 2026 The present research explores the addition of molybdenum (Mo)-doped ZnO nanoparticles synthesized using a hydrothermal method. The initial goal of the study is to remove the inherent downsides of pristine ZnO nanostructures corresponding to low electrical conductivity and low electrochemical activity by defect engineering. Pure ZnO nanomaterials were enriched with 2-percent (mol) of Mo and characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), UV–visible spectroscopy, photoluminescence (PL), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The XRD analysis indicated the formation of single-stage hexagonal wurtzite ZnO with the successful addition of Mo in the lattice as well as contraction of the lattice, decreased crystallite size (between 30 nm and 22 nm) and increased microstrain. The morphological analysis showed that the agglomeration is lower and increased heterogeneity on the surface of the doped sample. Optical studies revealed that the defect induced intermediate energy states between 3.5 eV and 3.7 eV, with the blue-shift of the absorption edge and increased bandgap of 3.5 eV to 3.7 eV. The photoluminescence measurements further proved the high defect density by the suppression of near-band-edge emission and high deep-level emissions. The electrochemical analysis demonstrated that the performance of Mo-doped ZnO has significantly improved, and a reduced resistance to charge transfer (7.7 kΩ). These enhancements have arisen due to the defect-assisted pseudocapacitive behavior, increased electroactive sites and improved charge transfer kinetics. The specific capacitance for pure and Mo-doped ZnO nanostructure was called 78 F/g and 91 F/g respectively. Finally, the present study demonstrates that dopant-induced structural changes and multifunctional behavior are directly correlated with Mo-doped ZnO, which makes such material a promising candidate to be used in energy storage, optoelectronics and sensing applications.
Beyond Graphene: Rise of 2D Materials P. Periasamy, Tony Dhiwagar, Kamalam Sambasivam Rajni, V. Dhineshkumar Evolution of Low Dimensional Biosensors in Food Safety Agriculture and Healthcare, 2026 Biosensors are indispensable analytical devices that deliver accurate measurements of biological or chemical reactions, providing key applications in fields such as food safety, agriculture, and healthcare. Graphene, a 2D honeycomb lattice structure comprising a single sheet of carbon atoms, has become an important building block for low-dimensional biosensors. Its derivatives, such as graphene oxide (GO) and graphene quantum dots, add essential characteristics such as high specific surface area, efficient electron transport, and excellent mechanical strength, which give them the potential to be used in a wide variety of applications. Graphene-based biosensors utilize these properties in various signal output approaches, each suited to different types of biomarker detection. Fluorescent detection uses graphene’s fluorescence quenching ability to detect targets, while electrochemical detection measures changes in current, potential, or impedance to signal the presence of a target biomolecule. The multifunctional detection capabilities of graphene-based sensors have widened their application in food safety, agriculture, and healthcare, providing innovative methods for multiple target detection. Sensors for multifunction detection combine recognition of multiple biomarkers with different signal readouts, expand the application range of biosensors, and offer new avenues for comprehensive analytical methods in diagnostics. The integration of graphene in biosensors represents a significant advancement in the field, aligning with the needs of food safety, agriculture, and healthcare to provide precise, rapid, and cost-effective analytical tools. This, coupled with ongoing research, underscores the potential of graphene-based biosensors to revolutionize these critical sectors. The integration of 2D materials, exclusively in food safety, agriculture, and healthcare, has transformed biosensors by offering unparalleled sensitivity and specificity.
Introduction to Chalcogenide-Based Nanocomposites Advances in Optoelectronics Energy Systems and Sustainability Periasamy Palanisamy, S. Satheeskumar Chalcogenide Based Materials for Optoelectronics Energy and Sustainability, 2025 Chalcogenide nanocomposites are nanosized materials wherein chalcogen elements (sulfur, S; selenium, Se, and tellurium, Te) are combined with a wide range of metals and/or semiconducting materials, have attracted researchers' interest due to their peculiar optoelectronic, energy storage and environmental sanitization characteristics. This chapter describes recent progress on the synthesis, properties, and applications of nanocomposites based on chalcogenides in the field of optoelectronics, energy, and sustainability. Potential applications include solar cells, light-emitting devices, photodetectors, energy storage systems (such as batteries and supercapacitors) and environmental sustainability-related fields such as photocatalysis and water purification. This chapter describes new trends and perspectives in the fabrication of chalcogenide nanocomposites, which are proposed as advanced materials for next-generation energy technology, including eco-friendly applications
Pioneering sensing solutions for in-situ monitoring of volatile organic compounds in soil and groundwater using chemiresistor sensor technology Periasamy Palanisamy, Maheswaran M. Sensors for Environmental Monitoring Identification and Assessment, 2024 The monitoring and classification of volatile organic compounds (VOCs) in soil and groundwater is a critical task in guaranteeing environmental protection and remediation of contaminated sites. Traditional methods of sample collection and off-site analysis could be expensive, laborious, and may not accurately represent in-situ conditions. To address these encounters, state-of-the-art sensing solutions using chemiresistor sensor technology have been developed for instantaneous, uninterrupted, and long-term monitoring of VOCs in the subsurface. The chemiresistor comprises of a chemically-sensitive polymer dissolved in a solvent and mixed with conductive carbon particles. The resultant ink is deposited onto thin-film platinum traces on a solid substrate. When VOCs come into interaction with the polymers, they are absorbed, initiating the polymers to swell and change the resistance of the electrode. This variation in resistance can be measured and recorded, providing information about the concentration of the VOCs.
Biogenic sorption: An intelligent and sustainable approach to reclaiming and reutilizing heavy metals in the Modern Era Periasamy Palanisamy, M. Kumaresan, M. Maheswaran Biosorption Processes for Heavy Metal Removal, 2024 The treatment of heavy-metal-bearing wastewaters is a critical environmental challenge, as access to clean drinking water becomes increasingly difficult due to pollution and rising water treatment costs. Traditional adsorbents derived from fossil fuels are not sustainable and can contribute to secondary pollution. To address this issue, researchers have turned to biogenic sorbents made from modern biomass as a promising alternative. These biosorbents utilize biological waste materials that would otherwise contaminate water systems, promoting a circular economy and sustainable water treatment practices. This chapter explores the potential of biogenic sorbents for water decontamination, focusing on their use in the removal of heavy metals from contaminated waters. Further, this chapter delves into the preparation methods, adsorbent types, adsorption mechanisms, and regeneration techniques employed with these biosorbents.
