Summary: The diving and surfacing device fabricated from thermo-sensitive poly(N-isopropylacrylamide) or a poly(N-isopropylacrylamide)-containing hydrogel can exhibit fast and reversible diving/surfacing cycles in response to changing temperature. Modulation of the interaction between poly(N-isopropylacrylamide) chains and water molecules at different temperatures allows for control of gel density through swelling and de-swelling, enabling the gel to surface in water when heated and sink when cooled. Reversible diving/surfacing cycles of the device can also be achieved when exposed to electrical and ultrasonic stimuli.

Summary: This project aims to design a smart window that responds to both electricity and heat, achieving energy efficiency, privacy preservation, and enhanced decorative attributes. By using a novel electrochromic material design and optimizing electrochromic devices, high-performance ECDs with fast color-switching speed and significant transmittance modulation are obtained. Additionally, a thermochromic gel electrolyte is created to provide excellent thermal insulation and further enhance the window's performance. Overall, this work showcases a prospective design pathway for the development of next-generation ultrafast-switching, and energy-efficient intelligent windows.

Summary: Biomineralizing organisms have the ability to generate structural materials with exceptional crystallographic control, and the nacro-prismatic pearl oyster demonstrates systematic textural changes in its biogenic ceramic. The textured gradients in the shell result in variations in Young's modulus, providing intrinsic toughening properties similar to those of compositionally-graded synthetic materials. This unique concept of gradation based on elastic anisotropy makes oyster shells potential blueprints for future bioinspired functional materials and damage-resistant ceramics.
