Selective Oxidation of Cellulose-A Multitask Platform with Significant Environmental Impact. Microplastics are often defined as plastic particles smaller than 5 mm in length, with a subset smaller than 1 m in length often referred to as nanoplastics. Carbon Block Water Filters These filters can reduce the high concentration of microplastics as these particles will be trapped and absorbed in the carbon surfaces. In a separate study, the researchers showed that the filter could also remove drug-based micropollutants from water. Healthy cities. Promoting excellence in science education and outreach.
