Development of a novel smart ceramic for microplastics detection and removal

Autor: Del Río Bonnin, Laura

The current socio-environmental and health problems that have arisen from the research of the presence of microplastics in the human body expose the need not only to reduce the use of plastics but to eliminate those that are already there. This proje

Most mammals sniff to detect odors, but little is known how the periodic inhale and exhale that make up a sniff helps to improve odor detection. In this combined experimental and theoretical study, we use fluid mechanics and machine olfaction to rati
