3D Printing of Deformable Multicolor Alternating-Current Electroluminescent Devices Through Rational Design of Functional Inks Jeongbin Park, Shakti Singh, Jinhwan Yoon Small, 2025 The development of flexible and customizable electroluminescent devices represents a significant challenge in advanced manufacturing. This paper introduces a novel approach for fabricating highly deformable, fully 3D‐printed alternating‐current electroluminescent devices through the rational design of UV‐curable functional inks. The devices feature a unique multilayer structure including a UV‐curable thiol‐ene crosslinked emission layer (ZBS‐t‐SE) and temperature‐responsive ionic hydrogel electrodes (FFP). The ZBS‐t‐SE demonstrates exceptional mechanical properties, with a strain of 259% at 727 kPa, whereas the FFP electrodes exhibit excellent printability through controlled micelle formation, high ionic conductivity (2.5 × 10⁻2 S cm−1), and stable performance under repeated deformation (>3000 cycles at 200% strain). The optimized devices maintain stable operation under various deformation modes, including stretching, bending, and twisting, achieving a maximum luminance of 267.4 cd m−2 at 200% strain. Furthermore, the 3D printing approach enables the fabrication of complex 3D structures with multi‐color emission through precise spatial control of functional materials, presenting a transformative strategy for next‐generation flexible electronics and display technologies.
Self-powered fluoride detection and removal system using waste material utilization and self-healing capabilities Shakti Singh, Chandra Bhan, Abhisikta Bhaduri, Manoj Kumar Gupta, Jinhwan Yoon, Chiranjit Maiti, Jiwan Singh, Bal Chandra Yadav Materials Today Communications, 2024 The current work outlines the finding of a distinctive method to detect hazardous fluoride ions in the water below permissible limits using a waste material-based self-healable triboelectric nanogenerator. In this work, the authors showed the steps involved to detect fluoride in a chemisorption-based self-powered sensor. The device is made-up of waste materials like butadiene-styrene rubber, used polythene bags, and used plastic sheets, and Lanthanum doped Polyaniline-Polypyrrole nanospheres , which validates the waste to energy conversion ability with maximum output voltage of ∼242 volts and 40 μA current. The present self-powered fluoride detection device displays a maximum sensor response of 12.10, a % sensor response of 1110 %, and limit of detection of 4.7 μM, which is far better than previous reports. The self-healing ability of Polydimethylsiloxane/Butadiene-Styrene rubber powder decorated with LaPP (lanthanum doped Polyaniline-Polypyrrole) nanospheres shows fast healing in ∼25 min with a healing efficiency of 99.9 %, which is one of the unique features of this device. Additionally, the present work also demonstrates not only recognition but the removal of fluoride ions using waste Juncus effusus biomass. The removal percentage of the fluoride was found to be 92.6 % having an adsorption capacity of 2.31 mg/g. In summary, this paper establishes a special way to sense the fluorides and their removals using waste materials.
Self-Powered Fluoride Ion Detectors Based on Piezoelectric Nanogenerators with Filler Materials Comprising Mn-Doped BaTiO3 Nanostructures and Carbon Nanotubes Abhisikta Bhaduri, Shakti Singh, Manoj Kumar Gupta ACS Applied Nano Materials, 2023 The current study depicts an exclusive technique to detect fluoride ions in water using a cost-effective self-powered sensing device using nanostructured Mn-doped BaTiO3 as the detecting element. The device is powered by a piezoelectric nanogenerator (PENG), whose substrate was modified by addition of the Mn-doped BaTiO3 nanomaterial and carbon nanotubes as fillers to generate high PENG output voltage sufficient for driving the fluoride detector. A highest voltage of 43.6 V and current of 1.23 μA was achieved by the modified PENG substrate. This substrate was then connected as the input to the fluoride detection film via a rectified voltage divider circuit. The device was found to detect fluorides in water mixed at different concentrations, with the highest sensor response of 32.69 and a limit of detection as low as 1.18 μM. This work enlightens a unique method to detect fluoride in a very efficient and inexpensive way.
Modified Fe3O4 Magnetite Core@Shell Type Nanomaterials for Highly-Responsive LPG Sensing: A Comparative Analysis Shakti Singh, Artur Dzeranov, Lyubov Bondarenko, Kamila Kydralieva, Gulzhian Dzhardimalieva, Arseniy Babaytsev, Gulsara Kugabaeva, Nina Golubeva, Bal Chandra Yadav Ecs Sensors Plus, 2023 The present work focuses on the synthesis of Fe3O4 magnetite core@shell type nanoparticles modified with three types of ligands: Magnetite with activated carbon (MAC), Magnetite with silica (tetraethoxysilane, TEOS, and 3-aminopropyltriethoxysilane, APTES) (MTA) and Magnetite with silica, APTES and humic acids (MTAH). The MTAH sample shows greater porosity in comparison to MTA, and MAC samples. The band gap of MTAH is 4.08 eV, which is higher than MTA (2.92 eV), and MAC (2.80 eV). Rietveld quantitative phase analysis of all derivatives was performed and compared with all three samples. The LPG sensing at room temperature shows the highest sensor response of 9.42, in comparison to 3.87 sensor response for MAC, and 4.60 for MTA. This approximately double sensor response increment is justified with the help of band gap, porosity, and size of all 3 the samples. The MTAH sample shows the lowest response-recovery time of 9.33 and 10.78 s respectively in comparison to MAC and MTA samples. In conclusion, this manuscript describes the synthesis procedure of different derivatives of Fe3O4 core@shell materials along with the relation of LPG sensing with different parameters of the materials.
