New fundamental physics research provides insights on the process of diffusion in complex systems such as living organisms. This new theoretical framework has broad implications for active surfaces, ...

Part of Biology (Single Science) Living together - Food and ecosystems Active transport is a process that moves molecules against a concentration gradient. The process requires energy. For plants to ...

Modifications to existing theories have enabled researchers to better understand and model the dynamics of systems which don't obey conventional laws of diffusion. In normal circumstances, particles ...

Microvascular Tissue Engineering: Tissue engineering has the potential to revolutionize healthcare. A significant challenge in tissue engineering is to overcome substrate mass transfer limitations, ...

For an organism to function, substances must move into and out of cells. Three processes contribute to this movement – diffusion, osmosis and active transport. Cellular respiration and transport - ...
