The substantial build-up of non-biodegradable plastic waste from packaging sector not only poses severe environmental threats but also hastens the depletion of natural petroleum-based resources. Presently, poly (3-hydroxybutyrate-co-3-hydroxy valerate) (PHBV), received enormous attention as ideal alternatives for such traditional petroleum-derived plastics based on their biocompatibility and superior mechanical properties. However, high cost of such copolymer, due to expensive nature of feedstock, inefficient microbial processes and unfavorable downstream processing strategies restricts its large-scale commercial feasibility in the packaging sector.

Article Synopsis
  • Liquid crystal materials face challenges in achieving bright displays and fast switching times, particularly when using pure ferroelectric liquid crystals, due to their passive nature.* -
  • A novel electro-optical device was created by adding a tiny amount (0.25 wt%) of bimetallic nanoparticles (Au@Ag NPs) to a ferroelectric liquid crystal matrix, resulting in a 29-fold increase in light emission and up to a 53% reduction in switching time.* -
  • The enhanced performance is attributed to the unique properties of the Au@Ag NPs, such as improved electron density and stability, which boost the electromagnetic field and mesogenic alignment within the liquid crystal matrix.*
