The high-affinity adsorption of a cationic dioctadecyldimethylammonium bromide (DODAB) bilayer to the yeast form of the fungal cell Candida albicans was studied as a function of DODAB dispersion method, DODAB concentration and cell number density (n) in pure water. As previously observed for bacteria, the number of liposomes adsorbed per cell decreased as a function of n, possibly owing to increased...

The adsorption of Cd onto two titanium dioxide nanoparticles (nTiO2) with distinct crystalline phases and sizes was investigated in conditions that can be found in freshwater systems (I=0.01 M, pH 6.0–8.5). Cd dynamic speciation was assessed by two distinct electroanalytical techniques: absence of gradients and nernstian equilibrium stripping (AGNES) and scanned stripping chronopotentiometry (SSCP)...
The factors that control Ni availability and adsorption in serpentine soils from the northeast of Portugal, which developed under temperate climacteric conditions, were investigated following characterisation of the soils' selected physicochemical properties.Ni bioavailability was assessed through complementary extractions. The results showed that surface-bound Ni in serpentine soils is primarily...
