Growth of the soil bacterium Stenotrophomonas maltophilia in the presence of selenite produced a mixture of two types of cells: those that contained numerous electron-dense bodies of elemental selenium and those that did not. Light diffraction and electrical impedance measurements indicated that the

Flow field-flow fractionation is introduced as a new tool applicable to protein studies. Specific advantages of this method are discussed, including the capability for measuring diffusivities and Stokes radii directly. even for trace components. The theoretical equations of flow FFF are summarized a
Sedimentation field-flow fractionation can be readily used to characterize the particle size distributions in metal hydrosols with particle diameters extending well below 0.01 pm. Processes that change the size distribution, such as particle growth or coagulation, can be investigated by this method.
