(polymer radius of gyration Rg=6 nm [20]), which would correspond to a hydrodynamic diameter of a single coil in solution of about 1.34 Rg≈ 8 nm [28]. An increase in particle radius does however not necessarily guarantee that the particles are stable against aggregation under high ...
The centrifuge supplied by Robinson, Inc., (Tulsa, Okla.) Model 620 was used. The temperature is set at 72° C. The top speed is about 2400 revolutions per minute (RPM) and the radius to the sandpack is 8 centimeters (cm), which gives a centrifugal force of 520 g. All weights ...
