Biological rarticles in liquid suspension exhibit varied electrophoretie mobili:y dependent upon the electric charge behavior of their surface constituents. The surface composition of a population of the same kind of biological particles is uniform in a constant environment. The microscope electrophoresis techniques for mobility and isoelectric point determinations of microscopic particles (bac...

By far, the analysis of particles heat and mass transfer in open nanosystems is of noticeable importance both in theoretical and practical researches. Due to a slotted and cylindrical systems resort we have been able to carry out some essential experimental investigations as well as provide new theoretical computations. The distinctive feature of nanosystems gas particles transport research is ...

The effective hydrodynamic size and free mobility of particles of varying aspect ratio were evaluated by Ferguson analysis of gel electrophoresis. The ligand layer thickness was estimated from the difference between the effective size and the size of the metal core from TEM imaging. The zeta potential of the particles was calculated from the Ferguson analysis result by applying conventional ele...

Following the demonstration that gravitational waves impart linear momentum, it is argued that if they are polarized they should impart angular momentum to appropriately placed 'test rods' in their path. A general formula for this angular momentum is obtained and used to provide expressions for the angular momentum imparted by plane and cylindrical gravitational waves. While the plane [1] and c...

Nanoscale particles are known to exhibit novel and unprecedented properties that make them quite different from their corresponding bulk-scale materials. The key differences are (i) an increased relative surface area and (ii) quantum size effects. Since the growth, catalytic activity and the various interactions with molecules (including biomolecules) occur at the surface of nanoparticles, a gi...

A comparative electron microscope study was carried out on ultrathin sections of bone marrow, spleen, lymph nodes, and mediastinal tumors from eighteen rats with leukemia induced by mouse leukemia virus (Gross). In organs of all eighteen rats with leukemia, two types of particles were observed: one type, described as virus particles of 990 A average diameter, with an electron-dense center of 63...

The optical bistability in a composite, composed of nonlinear metallic particles (spherical or cylindrical) with interfacial layers randomly embedded in a linear dielectric host, is investigated theoretically. It is shown that both interfacial property and the size of metallic particles can dramatically a!ect the optical bistable behavior, and the threshold value is more less in three dimension...

Novel trapped-particle asymmetry modes propagate on cylindrical electron columns when axial variations in the wall voltage cause particle trapping. These modes consist of E x B drifts of edge-trapped particles, partially shielded by axial flows of interior untrapped particles. A simple model agrees well with the observed frequencies and eigenfunctions, but the strong mode damping is as yet unex...
