Aqueous polyacrylic acid based gels: physicochemical properties and applications in cultural heritage conservation
Solutions of polyacrylic acid form strong gels upon the addition of bases. Two different gels have been studied by differential scanning calorimetry... -
Characterisation of aqueous solutions of ionic surface active agents by conductometry
Conductometry data were analysed to determine some equilibrium properties of sodium decylsulphonate aqueous solution. Temperature dependence of... -
Development of a pressure-controlled pendant-drop surface balance
A fully automated, pressure-controlled pendant-drop surface balance has been developed. It allows non-invasive surfactant adsorption kinetics studies... -
Colloidal systems in intense, two-dimensional laser fields
The properties of two-dimensional (2D) colloidal systems in the presence of a strong laser field are studied. By interfering three laser beams we... -
Nucleation and growth kinetics of colloidal silica
A stopped-flow, time- resolved small-angle X-ray scattering study of nucleation and growth of Stöber silica particles is presented. The measured... -

Wetting of low energy surfaces by perfluoropolyether carboxylic salts in aqueous solution
The study via dynamic contact angle (DCA) of a well-defined mixture of perfluoropolyether (PFPE) carboxylic salts has been carried out to evaluate... -
Oxidisable cationic detergent for gene therapy: condensation of DNA and interaction with model membranes
Cationic amphiphile-mediated delivery of plasmid DNA is the non-viral gene transfer method most often used. In the present work, we considered a new... -
C12E7-DPPC mixed systems studied by pyrene fluorescence emission
The lipid/surfactant mixed interactions between the lipids dipalmitoylphosphatidylcholine (DPPC) or egg phosphatidylcholine (EggPC) and the non-ionic... -
Brewster angle microscopy studies of the morphology in dipalmitoyl phosphatidyl glycerol monolayers spread on subphases of different pH
Dipalmitoyl phosphatidyl glycerol (DPPG) was investigated as Langmuir monolayers at the air/water interface by means of surface pressure measurements... -
Interactions of selected flavonoids with NaDS micelles
Critical micelle concentrations (cmc) and degree of counterion dissociation (β) of sodium dodecyl sulphate micelles, in the presence of two... -
Glycerolipid arginine-based surfactants: synthesis and surface active properties
The research on biomimetic surfactants is currently increasing given the biocompatibility of the natural systems. Amino acid-glycerolipid conjugates... -
Monitoring of the aroma of fruits at their surface by luminescence
Spectrofluorimetry has been used to detect in vivo the photoluminescence of native organic volatiles emitted from the surface of various fruits.... -

Cationic microemulsion hosting polynucleotides: effect of NaCl on host and guest
The structural features of the quaternary water-in-oil microemulsion CTAB/n-hexane/n-pentanol/water in the presence of fairly high concentrations of... -
Viscosity studies of pluronic F127 in aqueous solution
The viscosities of the triblock copolymer F127 [(poly(ethylene oxide))106-(poly(propylene oxide))70-(poly(ethylene oxide))106] in water and the... -
Rheology of starch-based colloidal microgels
Steady state rheology experiments were performed on aqueous suspensions of starch-based particles in dilute and concentrated regimes to quantify the... -
Langmuir monolayers of lipids at the water/air interface
In order to establish the mutual miscibility ofd ,l -dipalmitoylphosphatidylcholine (DPPC) and 4-methylumbelliferyl palmitate in a two-dimensional... -
Flashing of colloidal crystals in square wave electric fields
We have investigated the optical properties of colloidal crystals grown in confined parallel plate geometry and subjected to an alternating square...
