RAPID 3D PRINTING OF AEROGELS WITH BIOINSPIRED SURFACE STRUCTURES FOR SOLAR STEAM GENERATION

Resumen de: US20260152658A1

0000 A polyacrylamide-based aerogel may be an efficient solar vapor generation device. Internal pores of the polyacrylamide-based aerogel may provide capillary forces while elongated surface channels provide a transport force in response to the polyacrylamide-based aerogel contacting liquid. The polyacrylamide-based aerogel may be formed from a photocurable resin doped with reduced graphene oxide particles. The photocurable resin may be printed in layers in a micro continuous liquid interface projection process to form a polyacrylamide-based hydrogel. The polyacrylamide-based hydrogel may be immersed in water to form a swollen hydrogel structure. The swollen hydrogel structure may be frozen. The frozen hydrogel structure may be dried to form a polyacrylamide-based aerogel structure.

HEATING SYSTEM

Resumen de: US20260153266A1

0000 A heating system includes a thermal battery having a storage container configured to hold a first fluid and an opening configured to substantially expose the first fluid to atmospheric pressure. A fluid conductor is disposed through the first fluid and extends from an inlet point at the storage container to an outlet point at the storage container. The fluid conductor is configured to receive a second fluid at a first temperature at the inlet point and to supply the second fluid at a second temperature higher than the first temperature at the outlet point. Thermal energy stored in the first fluid is transferred to the second fluid through the fluid conductor while the first fluid remains substantially non-pressurized. The arrangement enables efficient on-demand heating while decoupling thermal storage from pressurized fluid delivery.

METHOD, DEVICE AND APPLICATION OF SOLID-STATE PHASE CHANGE HEAT STORAGE AND HEAT RELEASE OF BAROCALORIC MATERIALS BASED ON GLASSY-CRYSTALS AND ACTIVE CONTROL

Resumen de: US20260153291A1

0000 The present invention discloses a method, device and application of solid-state phase change heat storage and heat release of barocaloric materials based on glassy-crystals and active control, which belongs to the technical field of solid-state phase change energy storage. A glassy-crystal phase is an intermediate metastable state formed in the change process from a high temperature plastic-crystal phase to an ordered crystal phase, which can be obtained by cooling the high temperature plastic-crystal disordered state of the barocaloric materials quickly. Rapid cooling makes the high temperature disordered state of the material supercooled and frozen, thereby avoiding the full oriented order that generally occurs at low temperature. The material is applied with a small pressure, which can achieve the change from the glassy-crystal phase to the ordered crystal phase, thereby achieving heat release. The glassy-crystal phase has good thermal stability, thereby achieving long-term storage, long-distance transportation and controllable release of heat energy.
