摘要： Solar thermal devices are formed from a block of wood, where the natural cell lumens of the wood form an interconnected network that transports fluid or material therein. The block of wood can be modified to increase absorption of solar radiation. Combining the solar absorption effects with the natural transport network can be used for various applications. In some embodiments, heating of the modified block of wood by insolation can be used to evaporate a fluid, for example, evaporating water for extraction, distillation, or desalination. In other embodiments, heating of the modified block of wood by insolation can be used to change transport properties of a material to allow it to be transported in the interconnected network, for example, heating crude oil to adsorb the oil within the block of wood.

摘要： An ion-conducting structure comprises a metal-fibril complex formed by one or more elementary nanofibrils. Each elementary nanofibril can be composed of a plurality of cellulose molecular chains with functional groups. Each elementary nanofibril can also have a plurality of metal ions. Each metal ion can act as a coordination center between the functional groups of adjacent cellulose molecular chains so as to form a respective ion transport channel between the cellulose molecular chains. The metal-fibril complex can comprise a plurality of second ions. Each second ion can be disposed within one of the ion transport channels so as to be intercalated between the corresponding cellulose molecular chains. In some embodiments, the metal-fibril complex is formed as a solid-state structure.

摘要： A porous base substrate is infiltrated with a polymer material to form a hybrid substrate that combines the optical advantages of both. Prior to infiltration, the base substrate may exhibit relatively low optical transmittance. For example, the base substrate may be paper, textiles, aerogels, natural wood, or any other porous material. By infiltrating the base substrate with a polymer having a similar refractive index to that of the material of the base substrate, the transmittance can thus be improved, resulting in, for example, a transparent hybrid substrate that exhibits both relatively high optical haze and relatively high optical transmittance within the visible light spectrum. The hybrid substrate can thus serve as a base for fabricating electronic devices or can be coupled to electronic devices, especially optical devices that can take utilize the unique optical properties of the hybrid substrate.
