Covalent organic frameworks (COFs) have been hailed as next-generation materials for capturing water from air, powering dehumidifiers, and driving energy-efficient heat pumps. Built from lightweight and organic building blocks, these crystalline and highly porous materials are akin to molecular Lego sets: their geometry and chemistry can be tailored with precision. However, a significant issue remained: in humid air, COFs may collapse. /news/2025-09-molecular-rivets-porous-materials-collapsing.html Analytical Chemistry Materials Science Tue, 23 Sep 2025 12:50:01 EDT news677846571 PFAS are fluorinated compounds found in many everyday products, such as outdoor clothing and cookware like Teflon pans. This is because PFAS are durable, heat-resistant and dirt-repellent. Their stability is precisely what leads to problems: although potentially harmful to our health, these substances are scarcely broken down at all in the environment and are regarded as "forever chemicals." PFAS are also found in wastewater. Although they can be removed by filtration, this is a laborious process. /news/2025-09-ball-mill-technique-nanoscale-scaffolds.html Nanomaterials Tue, 23 Sep 2025 11:30:04 EDT news677845802 UNIST and Hanyang University researchers have developed a novel porous material capable of high-purity separation of xylene isomers at room temperature.
