The active concentration of a pesticide declines with time due to volatilization, absorption and translocation, microbial degradation, adsorption on soil particles and plant parts, chemical reactions, ...

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, ...

Diffusion is the movement of particles from a region where they are in high concentration to a region where they are in low concentration, and is one of the ways substances can move across the cell ...

Impact of dose density of adjuvant chemotherapy for locally advanced urothelial cancer. Background: Device-assisted intravesical mitomycin-C (MMC), including electromotive administration (EMDA) and ...

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.
