Placing concrete requires much more water than the cement needs for its hydration. This results in an important porosity in the hardened concrete, which accentuates the degradation of this material. By adding small amounts of polymeric admixtures, called s ...
The adsorption of ions at the interface between two immiscible electrolyte solutions (ITIES) is primarily controlled by the potential distribution across the interface, which in turn is influenced by the adsorption process. In the present paper, we simulat ...
The spectroscopic and electrochemical properties of two-dimensional electrostatic assembly of Au nanocrystals are examined on poly-L-lysine (pLys) modified gold electrodes. The surface preparation for the nanoparticle deposition involved the self-assembly ...
Despite progress during the last decade, the behavior of charged macromolecules, polyelectrolytes, including their interactions is not yet completely understood. In particular, interactions with oppositely charged surfaces, which play a significant role in ...
The addn. of inert particles of lighter d. and smaller diam. increases considerably the mass transfer coeff. in comparison to that of mono-component active particles at the same liq. velocity. This effect was applied to elimination of Cu ions by adsorption ...
Sequential adsorption of N atoms on a MgO(100) supported Fe-7 cluster is studied using a density functional approach. For the number of adsorbates varying between one and six, the most favorable adsorption geometries are determined and the corresponding po ...
A family of cationic polyelectrolytes possessing defined chain lengths, narrow chain length distributions, uniform charge d., but substituents of different hydrophilicity at the quaternary ammonium group served as model compds. for adsorption studies. Thes ...
