Incorporation of Cellulose-Based Aerogels into Textile Structures
Given their exceptional attributes, aerogels are viewed as a material with immense potential. Being a natural polymer, cellulose offers the advantage of being both replenishable and capable of breaking down naturally. Cellulose-derived aerogels encompass the replenish ability, biocompatible nature, and ability to degrade naturally inherent in cellulose, along with additional benefits like minimal weight, extensive porosity, and expansive specific surface area.

Metamaterial Perfect Absorbers for Controlling Bandwidth
Metamaterial absorbers have garnered significant interest due to their unique electromagnetic properties, which facilitate the efficient absorption of electromagnetic radiation in a specific frequency range or multiple frequency ranges. The metamaterial absorbers are designed based on artificially engineered structures that enable tailored absorption properties. These structures might include multiple resonances or incorporate electrical resistive components to achieve broadband absorption.

Food-Based Carbon Dots for Biomedical Applications
Thermal treatment is one of the common methods used in food processing to reduce microbial activity and control the presence of foodborne pathogens. During thermal processing, carbonization reactions are often observed in foods, which could result in the formation of carbon dots (CDs). Typical CDs are regarded as organic carbonization products with sizes less than 20 nm, exhibiting excitation-dependent fluorescence properties. They possess sp2/sp3 carbon skeletons and feature an abundance of functional groups and polymer chains within their structures. The surface of CDs is rich in hydrophilic compounds, including carboxyl, hydroxyl, and amine groups, contributing to their excellent water dispersibility.

Nanotechnology Platform for Advancing Vaccine Development Against COVID-19
The COVID-19 pandemic has had a profound impact on societies, public health, healthcare systems, and the world economy. Vaccination emerged as the most effective strategy to combat this infectious disease. For vaccination strategies, any conventional vaccine approach using attenuated live or inactivated/engineered virus, as well as other approaches, typically requires years of research and assessment. However, the urgency of the situation promoted a faster and more effective approach to vaccine development against COVID-19. The role of nanotechnology in designing, manufacturing, boosting, and delivering vaccines to the host to counter this virus was unquestionably valued and assessed.

Geopolymer Materials for Extrusion-Based 3D-Printing
3D-printing is a sustainable approach to geopolymer material manufacturing, promoting waste reduction, energy consumption reduction, and CO2 emission reduction. In addition, 3D-printing technology based on geopolymers confronts hurdles that must be overcome to produce high-performance goods. One of the most important aspects of the quality and accuracy of 3D-printed geopolymers is the design of the mixture. Utilising industrial waste from mining and building as well as alternate aluminosilicate sources are two ways to advance the development of printing geopolymer combination compounds.

Applications of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)-Based Materials
Among the various biopolymers derived from the PHA family, the copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), commonly known as PHBV, stands out for its inherent versatility. Unlike many other members of the PHA family that are derived from a single monomer and exhibit consistent physicochemical properties, PHBV offers the unique advantage of tunability. By adjusting the ratio of 3HB to 3HV monomers, the material properties can be tailored to produce products from flexible films to rigid molded objects. This adaptability made PHBV more versatile and expanded its potential applications.
