Environmental remediation and wastewater treatment using silver incorporated dual metal oxide polyaniline nano composites kinetic insights into Pb (II) and As (III) adsorptive removal E. Parthiban, S. Sudarsan, Haiter Lenin Allasi, Mary Vasanthi Soosaimariyan, D. Arun kumar, A. Kistan, K. Ranganathan Scientific Reports, 2026 Adsorption plays an important role in the elimination of toxic metal ions from wastewater. The Fe₃O₄/CuO–itaconic acid/polyaniline@Ag nanocomposite composed of itaconic acid (IA), polyaniline (PANI), dual metal oxides (Fe₃O₄/CuO), and silver nanoparticles in a 2:2:1:1 ratio was investigated. This nanocomposite was analyzed in FTIR, SEM/EDAX, TEM, and XRD spectra. The adsorption process has been influenced by pH, contact time, size of sorbent, and concentration of toxic metal ions in solution. The capacity of Pb(II) and As(III) ions equilibrium adsorption on nanocomposites increased with metal concentration characterized by the Langmuir isotherm exhibited qm values at 47.915 and 61.012 mg/g. Adsorption of Pb(II) and As(III) followed pseudo-first-order and pseudo-second-order kinetic parameters. Both models were applied. The pseudo-second-order kinetic analysis revealed maximum adsorption capacities (qₑ) of 123.76 mg/g for Pb (II) and 119.33 mg/g for As (III), corresponding to R2 values of 0.95694 and 0.94696, respectively.
Exploring the role of halloysite nanotubes in improving carbon fiber reinforced composite performance across diverse temperatures Shebaz Ahmed J P, Kaviyan M, Yamini Sivakumar, Sudarsan Shanmugavel Engineering Research Express, 2025 The impact of Halloysite Nanotubes (HNTs) as nanofillers on the mechanical and thermal characteristics of carbon fiber-reinforced polymer (CFRP) composites is the main focus of this investigation. This work examines the effects of adding 1 weight percent Halloysite Nanotubes (HNTs) to carbon fiber-reinforced polymer (CFRP) composites on their mechanical and thermal performance at different temperatures. Tensile and flexural tests were performed at four different temperatures, 30°C, 50 °C, 70 °C, and 90 °C, to determine the effect of HNT reinforcement. The experimental results indicated an 10%–20% increase in mechanical strength and a 10%–12% rise in thermal stability relative to standard CFRP composites. Dynamic Mechanical Analysis (DMA) showed notable improvements in the temperature at which glass transitions occur, the ability to manage loads, and the damping ratio, resulting in reduced strain and postponed failure of structures. In addition, including HNTs offered similar thermal and mechanical advantages as graphene while being a more economical option. Scanning Electron Microscopy (SEM) was utilized to analyze the microstructural features, the distribution of nanotubes, and the failure modes identified during tensile and flexural testing. The results show that HNTs can be a practical and affordable substitute for conventional nanofillers such as graphene, backing their application in high temperatures in aerospace, automotive, and engineering industries.
High-Entropy (Ce0.2Pr0.2Zn0.2Nd0.2Tb0.2)2Zr2O7 Zirconate Pyrochlore: A Promising Photocatalyst for Diverse Environmental Applications Mariappan Anandkumar, Shanmugavel Sudarsan, Venkata Ramesh Naganaboina, Naveen Kumar Bandari, Ksenia Sergeevna Litvinyuk, Shiv Govind Singh, Evgeny Alekseevich Trofimov Nanomaterials, 2025 Although fast-paced ongoing industrial growth, on the one hand, enhances the lifestyle of the population, on the other hand, it affects human health and the environment as a result of the discharge of pollutants. To address this, designing a novel and effective photocatalyst is necessary to mitigate increasing environmental pollutants. In the present work, we aim to synthesize a single-phase high-entropy zirconate pyrochlore oxide (Ce0.2Pr0.2Zn0.2Nd0.2Tb0.2)2Zr2O7 using a modified Pechini method. The physicochemical properties of the prepared nanoparticles were investigated using X-ray diffraction, UV-visible spectroscopy, field emission scanning electron microscopy, and X-ray photoelectron spectroscopy. The photocatalytic properties were examined using cationic dye (methylene blue), anionic dye (Congo red), and Cr(VI). Photocatalytic degradation experiments demonstrate exceptional efficiency in the removal of persistent organic pollutants. The photocatalytic results indicate that the prepared high-entropy (Ce0.2Pr0.2Zn0.2Nd0.2Tb0.2)2Zr2O7 zirconate pyrochlore oxide could effectively degrade dyes and reduce Cr(VI). Radical trapping experiments indicate that the degradation of dyes was driven by the hydroxyl radicals, superoxide radicals, and holes. Furthermore, the position of the valence band and conduction band promoted efficient photocatalytic reaction kinetics. The prepared photocatalyst remains structurally stable and can be reused three times without losing activity.
Phase Evolution of High-Entropy Stannate Pyrochlore Oxide Synthesized via Glycine-Assisted Sol–Gel Synthesis as a Thermal Barrier Coating Material Mariappan Anandkumar, Kannan Pidugu Kesavan, Shanmugavel Sudarsan, Dmitry Evgenievich Zhivulin, Natalia Aleksandrovna Shaburova, Ahmad Ostovari Moghaddam, Ksenia Sergeevna Litvinyuk, Evgeny Alekseevich Trofimov Nanomaterials, 2025 High-entropy ceramics have gained wider attention due to their structural integrity and stability, which can be used in various functional applications. Especially, high-entropy oxides exhibit excellent thermal stability, particularly at high temperatures. Thermal barrier coating materials must demonstrate good thermal stability without any phase transformation or phase separation, which is critical in aerospace and energy conversion applications. To address this, we have prepared new high-entropy stannate pyrochlore oxide nanoparticles with the composition (Gd0.2Nd0.2La0.2Pr0.2Sm0.2)2Sn2O7 through a simple glycine-assisted sol–gel synthesis. The phase evolution was probed at different heat-treatment temperatures from 1000 °C to 1500 °C. Among the temperatures investigated, a single-phase pyrochlore oxide was formed from 1300 °C without any impurity or phase separation. The obtained nanoparticles were characterized using various techniques, including X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), nanoindentation, and dilatometry to investigate their physiochemical and mechanical properties. The Vickers hardness of high-entropy oxides is 4.2 ± 0.33 GPa, while a thermal expansion coefficient (TEC) of 8.7 × 10−6 K−1 at 900 °C is calculated. The results show that the prepared high-entropy pyrochlore oxide can be a suitable candidate for thermal barrier coating.
Band-Gap Engineering of High-Entropy Fluorite Metal Oxide Nanoparticles Facilitated by Pr3+ Incorporation by Gel Combustion Synthesis Mariappan Anandkumar, Kannan Pidugu Kesavan, Shanmugavel Sudarsan, Olga Vladimirovna Zaitseva, Ahmad Ostovari Moghaddam, Daria Valerevna Iarushina, Evgeny Alekseevich Trofimov Gels, 2025 Tailoring the bandgap of a material is necessary for improving its optical properties. Here, the optical bandgap of high-entropy oxide Ce0.2Gd0.2Sm0.2Y0.2Zr0.2O2-δ (HEO) nanoparticles was modified using Pr3+. Various concentrations of Pr3+ (x = 0, 0.01, 0.02, 0.05, 0.075, 0.1, 0.15) were incorporated into the host high-entropy oxide using a gel combustion synthesis. After the gel combustion step, the powders were heat-treated at various temperatures (650 °C, 800 °C, 950 °C) for 2 h. The obtained Pr3+-incorporated HEO powders were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV–visible spectroscopy. The results indicate that, when the samples are calcined at 950 °C, a single-phase cubic fluorite structure is obtained without any phase separation or impurity. The optical absorbance red-shifts to higher wavelengths when the concentration of Pr3+ is increased. This reduces the bandgap of the material from 3.15 eV to 1.87 eV for Pr3+ concentrations of x = 0 (HEO-0) and x = 0.15 (HEO-6), respectively. The obtained HEOs can be suitable candidates for photocatalytic applications due to their absorbance in the visible region.
