Abstract:  Thermosets with permanent crosslinking networks have been extensively used in high-performance applications requiring thermal stability, chemical resistance, and structural integrity. However, they are extremely hard to be reprocessed and recycled using conventional methods, leading to ever-increasing contaminations in the waterways, wildlife, and human bodies. Covalent adaptable network (CAN) polymers can rearrange their macromolecular chain network by bond exchange reactions (BERs) with a simple stimulus (e.g. heat, light), which attribute to unusual properties that are not seen in conventional thermosets.…

Abstract: Advanced condenser surfaces with micro- and nanoscale wettability patterns have attracted much attention recently due to their potential to significantly increase performance in water harvesting and thermal management applications. Performance in these systems is measured in terms of the condensation rate, which is dictated not only by vapor-to-liquid phase change processes but also by the transport of condensed liquid droplets along the condenser surface. Computational fluid dynamics modeling offers a pathway to design surface patterns that optimize condensation rates,…
