Processes that do not involve the movement of molecules from an area of greater concentration to an area of lower concentration include active transport and bulk transport (vesicular transport). Active transport requires energy to move molecules against their concentration gradient, while bulk transport involves the movement of large particles or groups of molecules, often through endocytosis or exocytosis, rather than simple diffusion. Both processes can lead to an accumulation of molecules in areas of higher concentration.

He was also interested in human anatomy; often drawing out the human body, helping to successfully desgin the human body in his paintings and drawings.
