"The process is called sintering, which aggregates fine particles together into a more solid state. It is similar to powder metallurgy in the manufacturing of ceramics," continues Tsumori.

To get the mass, the team measured the total surface area of the plastic particles and incorporated a standard measure of thickness and density based on the most common microplastic waste types: polyethylene and polypropylene.

The T-vant adjuvant is derived from bacterial outer membrane vesicles, tiny particles that naturally stimulate the immune system.

The sky is blue because of atmospheric particles that scatter light in slower wavelengths.

This facilitates the reaction of the intermediates with each other to make a polyester, which gels into solid particles that can easily be separated out.
