Mopping up microplastics: Nanopillar-stabilized metal-organic framework removes contaminants from water

By Lisa McDonald / December 13, 2022

Adsorption is an effective way to remove microplastics from water by adhering them to an easily removable/retrievable surface. Researchers at RMIT University in Australia developed a nanopillar-stabilized metal-organic framework adsorbent that effectively removes microplastics from water, as well as the toxic pollutant methylene blue.

Monitoring mental stress: Nanosheet-type tin oxide gas sensors provide quantitative measurement of emotional tension

By Lisa McDonald / October 28, 2022

Determining when to seek help for mental stress can be difficult. However, the recent identification of discernible odor substances that emanate from the skin during emotional tension may offer a way to quantifiably measure mental stress. Two researchers in Japan propose nanosheet-type tin oxides could be used as gas sensors to detect these substances.
