pH-driven self-assembly of colloidal particles confined between parallel walls

Abstract: Small particles with dimensions of a few hundred nanometers tend to behave differently when confined in small spaces. Examples of such situations are easy to find in nature -- red blood cells flowing in capillaries come to mind -- and in modern technologies. When confined, small objects may spontaneously form ordered structures or they may find it impossible to move in the way they do in a larger space. We have found evidence that the electric charge on such small particles can strongly influence how they arrange themselves between two parallel walls and we want to use neutrons to understand this phenomenon. A better understanding of a system like this may lead to improvements in technologies ranging from lubrication to the healing of fractures.
