Even smaller than incendiary custard powder, nanoparticles take surface area to the extreme. Their minute size (100 nanometres max) means a massive surface area, which makes them way more reactive ...

"The iron powder was 26 times more effective than activated carbon per unit surface area," says Ji. Researchers outlined their findings in the study titled "Kinetic and Mechanism Study of PFOS ...

This is done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased: more particles are exposed to the other reactant there are ...

The powder has several advantages over other materials, according to its creators. Its porous design increases its surface area, which means more places to hold on to CO2 molecules. As a result ...

Custard powder makes a delicious dessert but also ... That's because, suspended in a cloud, all those particles have an enormous surface area exposed to oxygen. That makes them swift to combust.
