Dynamic Stern layers in charge-regulating electrokinetic systems: three regimes from an analytical approach

, 2018
We present analytical solutions for the electrokinetics at a charged surface with both non-zero Stern-layer conductance and finite chemical reaction rates. We have recently studied the same system numerically [Werkhoven {\em et al.}, Phys. Rev.

Antigen/adjuvant‐free liposome induces adjuvant effects for enhancing cancer immunotherapy

Exploration
Cancer vaccines are promising to treat malignancy by delivering antigens and adjuvants to elicit host immunity. Beyond aluminum adjuvants, liposomes show efficient adjuvant effects through regulating the accumulation, internalization and release of ...

Quantitative measurement of the surface charge density

, 2010
We present a method of measuring the charge density on dielectric surfaces. Similar to electrostatic force microscopy we record the electrostatic interaction between the probe and the sample surface, but at large tip-sample distances.

Variational approach for electrolyte solutions: from dielectric interfaces to charged nanopores

, 2010
A variational theory is developed to study electrolyte solutions, composed of interacting point-like ions in a solvent, in the presence of dielectric discontinuities and charges at the boundaries.

Magnetic reconstruction at (001) CaMnO$_3$ surface

, 1999
The Mn-terminated (001) surface of the stable anti-ferromagnetic insulating phase of cubic perovskite CaMnO$_3$ is found to undergo a magnetic reconstruction consisting on a spin-flip process at surface: each Mn spin at the surface flips to pair with ...

Scaling Theory of Polyelectrolyte Adsorption on Repulsive Charged Surface

, 2004
We studied polyelectrolyte adsorption on a repulsive charged surface by scaling analysis. At low ionic strength and low surface charge density in which a single polyelectrolyte is able to be adsorbed onto the surface, different regimes in the phase ...

Surface Complexes of Cr(VI) by Eucalyptus Barks

Indonesian Journal of Chemistry, 2022
The sorption mechanism of hexavalent chromium sorption on eucalyptus barks was evaluated as a function of solution pH for different adsorbent dosages, surface coverage, and the amount of adsorbent.

Charge writing at the LaAlO3/SrTiO3 surface

, 2010
Biased conducting-tip atomic force microscopy (AFM) has been shown to write and erase nanoscale metallic lines at the LaAlO3/SrTiO3 interface. Using various AFM modes, we show the mechanism of conductivity switching is the writing of surface charge ...
