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.

Bacterial cellulose gels, process for producing and methods for use

Assemblies and methods for modulating (e.g., near) infrared radiation are provided. Exemplary assemblies include a composite material interposed between a first substrate and a second substrate. The composite material includes plasmonic nanoparticles (e.g., nanoplates) dispersed in a nematic liquid crystal.

Assembly and method for actively controlling radiation transmission

Composite condensed matter material, devices including the composite condensed matter material, and methods of forming and using the composite condensed matter material are disclosed. The composite condensed matter material includes a host material and particles dispersed and suspended within the host material. The composite condensed matter material can exhibit one or more low symmetry phases and reconfigurable properties.

Disclosed are cellulose-based 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.

Cellulosic gels, films and composites including the gels, and methods of forming same

Materials that can be templated by one or more of biological material and biologically-derived material, structures including such materials, and methods of forming and using the materials and structures are disclosed. Exemplary materials and structures can be used to reflect, polarize and/or retard electromagnetic radiation.

Templated materials, structures including the materials, and methods of using and forming same

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).

Insulated assemblies and methods of forming and using same

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, depending on the solvents in the gels.

Cellulose-enabled orientationally ordered flexible gels

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.

Cellulose enabled orientationally ordered flexible gels

Disclosed herein are compositions, comprising one or more types of surface modified anisotropic nanoparticles dispersed in a liquid crystal. The compositions provide tunable methods for modifying light and energy flow.
