Abstract: Disclosed are cellulose-based 5 flexible aerogels and xerogels containing bacterial cellulose nanorods, ribbons, fibers, and the like, wherein the gels have tunable optical, heat transfer, and stiffness properties. Further disclosed are highly transparent and flexible cellulose nanofiber-polysiloxane composite aerogels featuring enhanced mechanical robustness, tunable optical anisotropy, and low thermal conductivity.

Abstract: Disclosed are cellulose-based flexible gels containing cellulose nanorods, ribbons, fibers, and the like, and cellulose-enabled inorganic or polymeric composites, wherein the gels have tunable optical, heat transfer, and stiffness properties. The disclosed gels are in the form of hydrogels, organogels, liquid-crystal (LC) gels, and aerogels. Further disclosed are highly transparent and flexible cellulose nanofiber-polysiloxane composite aerogels featuring enhanced mechanical robustness, tunable optical anisotropy, and low thermal conductivity. Further disclosed are gels comprising cellulosic material derived from bacteria and processes for preparing bacterial cellulose gels and methods of use.

Abstract: A method and system of using a supercritical fluid are disclosed. Exemplary methods include using temperature and pressure variation (e.g., above or below supercritical conditions) to remove material from a substrate to form separated and to cause movement of fluid within the system.

Abstract: Insulated assemblies, insulation units including an assembly, and methods of forming the assemblies and units are disclosed. Exemplary assemblies include a first pane of material, a second pane of material, and one or more monolithic insulating layers interposed between the first pane of material and the second pane of material. The insulating layer can exhibit a thermal conductivity less than 26 mW/(K.m).
