报告摘要：
Addressing global challenges necessitates advancements in energy and water sustainability. Direct solar desalination, for instance, holds immense promise for alleviating the worldwide freshwater crisis.This presentation will delve into practical considerations for developing solar heating and radiative cooling applications that promote water and energy sustainability. Specifically, I will discuss our recent advancements, spanning manufacturing to application development. We will begin by exploring our research efforts to create low-costsolar-drivenevaporation architectures using photothermal materials and systems. Additionally, we will discuss the potential applications of these architectures for zero-liquid-discharge water treatment using evaporation ponds. However, if the evaporated moisture cannot be collected, it merely contributes to atmospheric pollution. As the entropy sink, the cold source plays a crucial role incompleting the thermodynamic cycle of all heat-producing technologies. The unique challenge lies in obtaining coldness from renewable andsustainable sources. In the second part of this presentation,we will discussourrecent efforts on radiative cooling inwater and energy sustainability. Specifically, we will examine the potential of passive cooling technology to recycle atmospheric water. We will also highlight potential pitfalls to avoid in radiative cooling reporting, as summarized in our recent work.

报告摘要：
生物蛋白通道凭借其精确的亚纳米限域空间和独特的表面化学特性，可快速且选择性地传输水、离子和分子，在许多生命过程中起着关键作用。受生物通道的启发，构建具有类似结构和功能的人工通道并开发相应的膜材料与高效节能的膜分离技术，对水净化、石油精炼、化学品生产和碳捕获等众多工业过程具有重要意义。二维材料因其原子级厚度和独特的理化性质，有望成为新一代具有超高渗透性和选择性分离膜的纳米构筑单元。然而，将二维材料膜用于亚纳米尺度的精确分离过程仍面临诸多关键挑战，如控制非选择性缺陷、调节孔径分布以及在工业条件下保持长期稳定性等。
本报告将探讨如何设计、构筑和调控二维材料通道，并研究其在亚纳米尺度下对气体、液体和离子的选择性传输特性。内容主要包括：（i）有序二维通道膜的构筑，（ii）二维通道的调控策略，以及（iii）二维膜的分子工程设计。此外，报告还将讨论这些膜材料在类工业条件下的稳定性，并探索其在能源、环境和生物电子等领域的应用潜力。
