“Laser-Powered Precision at Scale: Revolutionizing Supercapacitor Manufacturing Cost-Effectively” Satnamkaur S. Mattu, Dhruv Dhoke, Ujjwal Chamate, Jyoti Shahu, Preeti Mangrulkar, Abhay Deshmukh Advanced Sustainable Systems, 2026 Miniaturized and flexible energy storage systems are critical for next‐generation microelectronics, yet scalable fabrication remains a fundamental challenge. Here, we demonstrate a rapid, ambient‐processable strategy to fabricate flexible micro‐supercapacitors (MSCs) by direct laser‐induced carbonization of Co@ZIF‐based (a combination of ZIF‐8 and ZIF‐67) metal–organic framework (MOF) films deposited on commercial cellulose paper. This substrate‐integrated approach combines a simple vacuum filtration process with CO 2 laser scribing, enabling the in situ formation of porous carbon–metal oxide hybrid electrodes in seconds, without the need for high‐temperature or inert‐atmosphere processing. We show that the morphology and electrochemical performance of the MSCs can be precisely tuned by adjusting the laser scribing parameters, with optimal performance achieved at a scan speed of 650 mm s −1 . The resulting devices exhibit an areal capacitance of 724.86 µF cm −2 , robust cycling stability over 9000 cycles, and dual‐polarity operation. Integration into a low‐voltage, USB‐powered circuit further validates the device's functional applicability. This work introduces a cost‐effective, sustainable, and scalable platform for high‐performance micro‐energy storage, bridging the gap between laboratory‐scale concepts and real‐world implementation.
Understanding the structural changes, interfacial mechanisms, and mechanical properties of polymer/MWCNT nanocomposites after microwave treatment Swamini Chopra, Kavita Pande, Amisha Kelkar, Shrikant Deo, Jash Panchmatiya, Sumitra Sharma, Abhay Deshmukh, Dilip Peshwe Polymer Composites, 2025 The use of microwave radiation for the post‐processing treatment of engineering polymers is a recent trend not seen by many. In the case of polymers, their crystalline nature is a significant factor in optimizing the treatment time for maximum improvement in mechanical properties. With the advent of nanomaterials, the aim of the present work is to explore the possibility of post‐processing microwave treatment on the structure and property relationships in MWCNT‐reinforced polymer matrices. The microwave‐activated nucleating tendency of MWCNTs was found to be promoting molecular chain rearrangement in poly‐amide (PA) and poly‐butylene‐terephthalate (PBT) nanocomposites. This considerably improved the mechanical characteristics of the composites by facilitating the rearrangement of the crystalline segments of the polymer matrix. The wear performance of PA nanocomposite increased by 30%, while the elongation of PBT nanocomposite increased by 93%, after a treatment of only 15–20 s. However, comparing with previous studies, it was found that, similar to virgin polymers, the treatment time needed for maximum improvement in polymer/MWCNT nanocomposites is hugely dependent on polymer matrix crystallinity as well. A detailed analysis of the microwave‐treated nanocomposites' structure and mechanical properties illustrates the post‐processing microwave treatment as a time‐efficient, cost‐effective, and environmentally friendly technique.Highlights Direct use of microwave radiation to heat the finished polymeric component. Microwave treatment brings about structural changes resulting in enhanced properties. Instantaneous heating is a key reason for the systematic arrangement of polymeric chains. Microwave‐activated nucleating tendency of MWCNTs also promotes chain arrangement. Properties increase as high as 30% wear rate and 93% elongation.
Electrodeposition of porous metal-organic frameworks for efficient charge storage Deepa B. Bailmare, Boris V. Malozyomov, Abhay D. Deshmukh Communications Chemistry, 2024 Efficient charge storage is a key requirement for a range of applications, including energy storage devices and catalysis. Metal-organic frameworks are potential materials for efficient charge storage due to their self-supported three-dimensional design. MOFs are high surface area materials made up of coordination of appropriate amounts of metal ions and organic linkers, hence used in various applications. Yet, creating an effective MOF nanostructure with reduced random crystal formation continues to be a difficult task. The energy efficiency and electrochemical yield of bulk electrodes are improved in this study by demonstrating an effective technique for growing MOFs over a conducting substrate utilizing electrodeposition. An exceptionally stable asymmetric supercapacitor is created when activated carbon cloth is combined with the resulting MOF structure that was directly synthesized via an electrochemical method resulting in 97% stability over 5k cycles which is higher than conventional processes. High performance in supercapacitors is ensured by this practical approach for producing MOF electrodes, making it a suitable structure for effective charge storage. Metal-organic frameworks (MOFs) are promising charge storage materials due to their high surface area, tunable pore size, and chemical diversity, but reliable and easy syntheses of MOF conductors are needed. Here, the authors report the electrodeposition synthesis of highly conductive cobalt MOF films and their application in a supercapacitor with a power density of 480 Wkg-1 and 5k cycle stability.
Tailoring iron MOF/carbon nanotube composites as flow electrodes for high-performance capacitive deionization Maheshwari Akulwar, Deepa B. Bailmare, Ravin M. Jugade, Abhay D. Deshmukh Discover Materials, 2024 Capacitive deionization techniques are of interest in water treatment technology due to their low cost, excellent efficiency, and environmental friendliness. Currently, metal–organic frameworks are highly impactful candidates for use as electrode materials in electrochemistry. It provides a large pore volume, good chemical stability, and a high specific surface area. Tuning metal–organic frameworks with carbon materials will have a good impact on electrode materials with increasing performance. This study shows a facile and effective strategy for arranging flow capacitive desalination technology for salt removal. The conducting network of Fe-MOF/CNTs provides rapid electron transport and offers a high diffusion length of ions. This material exhibited excellent desalination performance, with a high salt adsorption of 80.575 mg/g at 1.6 V at an initial NaCl concentration of 1000 mg/L. Overall, the facile method and fabrication strategy greatly advances water treatment applications.
