Hi, I’m Seungbeom Cho, a second-year student at Korean Minjok Leadership Academy in Hoengseong, South Korea. I’m passionate about chemistry, environmental science, and materials science. I explore biodegradable polymers in our school lab, volunteer for local water-quality monitoring, and conduct experiments on catalytic upcycling. In my spare time, you’ll often find me playing basketball or enjoying R&B music. I look forward to meeting other water enthusiasts in Stockholm and exchanging ideas that can help advance sustainable science together.
Tell us what the water concern in your country is!Global warming accelerates desertification in South Korea’s southeastern counties, depleting reservoirs and jeopardizing crops. Securing dependable water—via rain-harvesting infrastructure, reclaimed wastewater, and precision irrigation—is now critical. Because migrating rainfall patterns transcend borders, international cooperation, data sharing, and joint contingency planning are imperative to safeguard regional water security for future generations.
This is what I think is one of the solutions for a sustainable future:A sustainable future requires universally deployable water-harvesting technologies such as MOF-based sorbents, which can extract moisture from air in almost any climate. To realize their promise, we must prioritize research that lowers production costs, boosts capture–release efficiency, and scales manufacturing, making safe, clean water accessible to all communities.
Energy-Efficient Atmospheric Water Harvester under All Climatic Conditions using Metal-Organic Frameworks
As water scarcity worsens due to climate change, atmospheric water harvesting is emerging as a sustainable solution for freshwater supply in regions with limited access. This study presents an energy-efficient atmospheric water harvesting device based on metal–organic frameworks (MOFs). Unlike existing systems that operate only once daily using temperature differences between day and night or require electricity, the proposed device collects water multiple times daily without external power. Integrating MOFs with manual vacuum pump and low-temperature sources like soil accelerated water collection up to fourfold compared to non-vacuum conditions. Incorporating MOFs into a porous sponge shaped into beads or films enhanced water uptake efficiency and portability. This approach offers a promising strategy for freshwater production across diverse climate conditions.
