The streaming potentials of two different nanofiltration membranes were studied with several electrolyte solutions to investigate the influence of salt type and concentration on the zeta potential and kinetic surface charge density of the membranes. The zeta potentials decreased with increasing salt concentration, whereas the kinetic surface charge densities increased. The kinetic surface charg...

Local surface charge density of lipid membranes influences membrane-protein interactions leading to distinct functions in all living cells, and it is a vital parameter in understanding membrane-binding mechanisms, liposome design and drug delivery. Despite the significance, no method has so far been capable of mapping surface charge densities under physiologically relevant conditions. Here, we ...

We present numerical self-consistent field calculations in a two-gradient cylindrical coordinate system for a ~translationally restricted! quenched polyelectrolyte star which is electrostatically attracted to an oppositely charged surface with homogeneous surface charge density at a given ionic strength of a 1:1 electrolyte. The results prove that without any additional driving force for adsorp...

The drag of fluid flow at the solid-liquid interface in the micro/nanoscale is an important issue in micro/nanofluidic systems. Drag depends on the surface wetting, nanobubbles, surface charge and boundary slip. Some researchers have focused on the relationship between these interface properties. In this review, the influence of an applied voltage on the surface wettability, nanobubbles, surfac...

objective(s): iscomatrix vaccines have now been shown to induce strong antigen-specific cellular or humoral immune responses to a broad range of antigens of viral, bacterial, parasite or tumor. in the present study, we investigated the role of iscomatrix charge in induction of a th1 type of immune response and protection against leishmania major infection in balb/c mice.  materials and methods:...

The Fermi surface topology plays a crucial role in the study of high-temperature superconductivity cuprates. conventional method for determining is maximum spectral intensity method, which involves numerical analytical continuation Matsubara data one-body Green's function. However, sensitive to noise or precision data, and hence not always reliable. With this mind, we propose simple specific no...
