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 sui
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

We developed a new apparatus to measure the adhesive force between particles with a high resolution of approximately 2 nN. The force was measured directly by applying a pulling force to the particles with a contact needle. In addition, the separation process was observed with a 3CCD camera during th
