✦ Synopsis


If the radii a and b are large and if R Γ‡ a / b A result for the integral of R 012 over two spheres of radii a and b is given. This result, together with Hamaker's result for the integral of R 06 , leads to an expression for the integral of the Len-

nard-Jones potential over two spheres that is suitable for calculations involving colloidal particles.

An atomic force microscope was used to measure the forces between a silica sphere (diameter 10 ΞΌm) and a n-decane droplet (diameter 0.3 mm) in water. Force-distance profiles showed a weak attraction and adhesion due to van der Waals forces. When the anionic surfactant sodium dodecyl sulfate was adde
