A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Gases diffuse between water and capillaries in gills, which are immersed in the flow of water. In contrast, diffusion of gases between inhaled air entering the lungs and capillaries occurs within ...

In diffusion, coffee particles move from the coffee machine (an area of high concentration) to the rest of the coffee shop (an area of low concentration). In gases and liquids, particles move ...

they applied dynamic chemical interactions to adjust pore dynamics and reverse isomer diffusion preferences. Their work is published in Nature Communications. Chemical (gas, hydrocarbons ...
