Electrically tunable adaptive lenses provide several advantages over traditional lens assemblies in terms of compactness, speed and efficiency. Such a lens is a broadband device with its performance independent of light polarization. Here we developed a process for making liquid lens with tunable focal distance on applying electrical input. Materials used to make the lens were polydimethylsiloxane...
Cellulose nanocrystals (CNC) extracted from trees, plants, algae, tunicates, and bacteria are considered today as a novel class of nanomaterials which many attracting properties such as optical and mechanical properties. These properties vary depending on how CNCs are aligned and formed in the composites. In this study, different processing such as random casting, shear casting and electro spinning...
Cellulose based materials display positive uniaxial birefringence. How cellulose is processed and manufactured can maximize this anisotropy. In this study different processing techniques were used to produce cellulose nanocrystal (CNC) thin film. Different processing conditions and techniques were used to align CNC fiber in CNC thin film. After CNC based film was produced, it was optically tested...
