To improve access to safe and affordable drinking water, MIT engineers are tapping into an unconventional source: the air. They developed a new atmospheric water harvester and showed that it efficiently captures water vapor and produces safe drinking water across a range of relative humidities, including dry desert air.
A team of Korean scientists has developed an innovative green technology that transforms plastic waste into clean hydrogen fuel using only sunlight and water.
Researchers at the Institute for Basic Science (IBS) Center for Nanoparticle Research, led by Professor KIM Dae-Hyeong and Professor HYEON Taeghwan of Seoul National University, announced the successful development of a photocatalytic system that produces hydrogen from PET bottles. The key innovation lies in wrapping the photocatalyst in a hydrogel polymer, which helps it float on water and stay active even under harsh environmental conditions.Researchers have unveiled the first comprehensive analysis of China's urban expansion from 1990-2020, revealing how cities have adapted to their environments and faced varying disaster risks. The study found that while 83% of urban development occurred in suitable areas, 14% expanded into high-risk zones, with eastern regions facing water-related disasters, western regions threatened by earthquakes, and northeastern areas vulnerable to extreme cold.
