Current work discussed advancements in nano cellulose preparation techniques, innovative methods, and cutting-edge applications. The ease of nano cellulose excels as a material for tissue engineering scaffolds, wound dressings, flexible and sustainable electronics, and drug delivery systems in the biomedical industry. It is desirable component in composites due to its remarkable reinforcing abilities in polymers. The use of environmental applications such as water purification, oil spill cleanup, and biodegradable packaging is also highlighted in this research. The studies emphasize the need for more investigation and optimization of extraction processes, characterization, and applications. This multidisciplinary study intends to motivate academics and scientists to fully utilize nano cellulose and contribute to the creation of environmentally friendly and sustainable solutions across a range of industries.

Supercapacitors have garnered substantial interest owing to their capacity to deliver power effectively for short-term applications. However, current supercapacitors suffer from limited stability and low-capacity storage. Metal-organic frameworks (MOFs) have emerged as a promising solution due to their high surface area and abundant active redox sites. MOF-based electrodes combined with aqueous based electrolytes have shown potential to enhance supercapacitor performance. While there is limited literature on MIL-101(Fe) MOF-based electrodes, a comparative study was conducted to investigate the supercapacitor performance of MIL-101(Fe) electrodes synthesized using hydrothermal and microwave-assisted processes. Processing parameters, such as the method used, alter the microstructure, morphology, and uniformity of supramolecular chemistry, impacting electrochemical characteristics. This study aimed to determine the active redox reactions, chemical stability, surface area, adsorption characteristics, and electrochemical characteristics of the electrodes. The electrodes from hydrothermal synthesis [MF(ht)] exhibited excellent electrochemical activity in comparison to the microwave-assisted [MF(m)] electrodes in the three-electrode configuration. At a high current density of 7 A/g, the MF(ht) electrode displayed a remarkable specific capacitance of 775.6 F/g and a good cyclic stability (82% @ 10 A/g) after 5000 galvanostatic charge–discharge cycles. At a current density of 1 A/g, the two-electrode configuration of MF(ht) yielded a high energy density of 74.7 Wh/kg at a power density of 2160 W/kg and a decent cyclic stability after 5000 cycles. The results suggest that the MF(ht) electrodes possess remarkable electrochemical properties that make them a promising candidate for advanced applications in energy storage.
