EN Nanosuspension was made using wire explosion in the liquid. Providing that silver and copper proportions are right, the liquid could be strongly sterile. Suspension which contains only silver particles has also antibacterial properties. We can control dimensions of metal in water by varying voltage,[...]

PL Omówiono zalety wstępnie zhydrolizowanych koagulantów glinowych o różnej alkaliczności, tzw. chlorków poliglinu. Badano próbki wody z Odry i Oławy różniące się temperaturą i poziomem zanieczyszczenia. Chlorki poliglinu zapewniły większą destabilizację koloidów oraz efektywniejsze usuwanie zanieczysz[...]
EN The advantages of polyaluminum chlorides (i.e. prehydrolyzed aluminum coagulants differing in basicity) are specified. Expts. were carried out on riverine water samples (from the Odra and its tributary, the Olawa) which varied in temp. and pollution level. Polyaluminum chlorides yielded a greater [...]

EN Irreversible adsorption of colloid particles at heterogeneous surfaces was studied experimentally. The substrate of controlled heterogeneity was produced by covering mica sheets by colloid iron oxide (hematite) particles to a desired concentration. The particles of averaged diameter of 70 nm were pr[...]

EN Irreversible adsorption of colloid particles at heterogeneous surfaces was studied theoretically. In contrast to previous models, the dimension of the adsorption sites having the shape of circular discs, was comparable with the size of adsorbing spheres. Adsorption was assumed to occur if the sphere[...]

EN Electrostatic interactions of two spherical particles immersed in an electrolyte mixture were analyzed theoretically. A numerical scheme was developed for solving the governing Poisson-Boltzmann equation expressed in the bispherical co-ordinate system. The method was based on the alternating directi[...]

EN Viscosity of colloid silica was determined as a function of the volume fraction varied between 0 and 0.37. A new method of viscosity measurements was applied, based on determination of particle sedimentation velocity. The sedimentation velocity was calcu-lated from the kinetics of irreversible adsor[...]

EN Arguably the most important factor in the wet end of your papermachine is Colloidal Retention. Colloidal trash can create problems with runnability and sheet quality. It doesn't let your retention system or additives work well, and it leads to deposits, holes, breaks, and overall papermaking chaos. [...]

EN The random sequential adsorption (RSA) approach was used to analyse adsorption kinetics of charged spheres at charged surfaces precovered with smaller sized, likely charged particles. The algorithm of M. R. Oberholzer et al. [20] was exploited to simulate adsorption allowing electrostatic interactio[...]
