Abstract: Cell engineering, soft robotics and wearable electronics often desire soft materials that are easy to deform, self-heal, and relax stress. Hydrogel, a type of hydrophilic networks, which can be made responsive to environmental stimuli, are often used in the aforementioned applications. However, conventional hydrogels often suffer from poor stretchability and repairability. Here, we report hydrogels consisting of boronic ester dynamic covalent bonds in a double network of poly(vinyl alcohol) together with chitosan, demonstrating extreme stretchability (up to 310 times of the original length), instant self-healing (within 5 sec), reusability as well as inherent adhesion. Their instant stress relaxation as a result of low activation energy of the boronic ester bond exchange (less than 20 KJ/mol) contributes to the extreme stretchability and self-healing behaviors.

Abstract: The present invention introduces a capillary distillation method comprising the following steps: heating wastewater, subsequently directing the heated wastewater to one end of a water-diversion fiber material. Through capillary action, the heated wastewater permeates the water-diversion fiber material, diffusing downward along microchannel pathways within the material. Upon reaching the surface of the water-diversion fiber material, the wastewater evaporates. Water vapor is then directed to a condensation module, where it undergoes condensation and collection, resulting in the production of fresh water.

Abstract: Multi-state switchability is highly desirable in optoelectronic devices. For liquid crystal (LC) based devices, the stability of any configuration is achieved through a balance between imposed interactions and the LC's orientational elasticity. In most cases, the latter acts to resist deformation. By combining surface topography and chemical patterning, provided here are the effects of saddle-splay orientational elasticity, a property that, despite being intrinsic to all LCs, is routinely suppressed. Utilizing theory and continuum elastic calculations, provided here are example conditions for which, even using generic, achiral LC materials, spontaneously broken surface symmetries develop. Also provided are multi-stable devices in which a weak, but directional, applied field switches between spontaneously-polar surface state domains. The disclosed approach is useful in low-field and fast-switching optoelectronic devices, beyond those attainable by current technologies.
