  "textContent": "The global shortage of freshwater has become a critical challenge. Conventional water treatment relies heavily on fossil fuels and associated infrastructure, which can make it unsuitable for remote and harsh regions. In contrast, solar thermal evaporation is a promising alternative, but its application is limited by material performance and production constraints.",
