The planet must deal with the two main concerns of the twenty-first century: energy storage and protecting the environment. Energy storage systems urgently require green and sustainable electrode materials due to the rise in worldwide demand for energy and severe environmental damage. The biopolymer-based device reduces e-waste and environmental issues caused by conventional electronic devices. Nanocellulose is a solid choice for green electronics, due to its unique properties, like being eco-friendly, cost effective, biodegradable, having great mechanical strength, and remarkable optical clarity. With its exceptional qualities, sustainability and distinctive structures, nanocellulose has become a hopeful nanomaterial with enormous potential for creating useful energy storage systems. This review aims to offer novel viewpoints on flexible composites made of nanocellulose or nanocellulose-based materials for enhanced energy technologies. Initially, a brief introduction to the special structural features and attributes of nanocellulose is made. To improve these composites’ performances, the structure-property-application interactions must be addressed. The most recent uses of nanocellulose-based composites are then thoroughly reviewed. These include flexible solar cells, supercapacitors (SC), lithium-ion batteries and developing energy device innovations. Finally, nanocellulose-based composites for the next generation of energy devices are offered, along with their current difficulties and potential future developments.

In recent times, there has been a significant increase in bone-related diseases, posing a pressing challenge in the field of medicine. While bone tissues possess a natural self-healing capability, severe injuries can lead to a loss of this regenerative potential. Traditional transplantation approaches, despite being billion-dollar industries, are riddled with issues such as a scarcity of organ donors, a high risk of infections, and post-transplant complications. To address this issue, tissue engineering has demonstrated to be a possible alternative for wound remodeling and organ transplantation. Recently, biopolymer-based aerogel has caught tremendous attention as a result of its exceptional qualities in the field of biomedical engineering. This review aims to provide comprehensive information on the properties and recent research regarding the use of polysaccharides like chitosan, cellulose, alginate, hyaluronic acid, and starch-based aerogels in bone tissue engineering. It highlights the potential of these aerogels in addressing bone-related issues and discusses the obstacles and future prospects of polysaccharides in tissue engineering applications.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is the most promising and appropriate microbial biopolymer as a replacement for conventional petroleum-based non-biodegradable polymers, due to its excellent biodegradability and biocompatibility. However, it has a few limitations that prevent it from being used commercially, including low mechanical strength, hydrophobicity, poor thermal and electrical properties, difficult processing, and high cost. Recent researches has shown that it is the most promising natural biopolymer, particularly for packaging. To use PHBV in biocomposites, methods of compensating for PHBV's shortcomings, such as adding fillers, more cost-effective and efficient production methods, or alternative PHBV sources, must be developed. Numerous researchers are looking into ways to improve characteristics and lower prices by developing biocomposites to address environmental safety concerns with PHBV, developing and discovering more affordable biological PHBV production methods, discovering new microbial strains or strain combinations, or developing less expensive PHBV extraction methods. The current review provides a detailed description of the studies conducted to improve the properties of PHBV as biocomposites by employing less expensive yet efficient reinforcements, particularly for food packaging applications. Furthermore, nanocellulose can be studied further as a PHBV biocomposites enhancement to improve properties and functionalities from various optimal sources in order to produce fully degradable bionanocomposites for sustainable packaging applications.
