Prokopenko, Registration Date 07-06-2010 Organization F.D. Ovcharenko Institute of biocolloidal Chemistry NAS of Ukraine popup.description2 Account is devoted to the investigation of nanochemical and physical-chemical transporting of nanoparticles providing contact interactions of solid surfaces and micro particles during theirs contacting and structure forming. The role of such interactions in contacting metal dispersed systems in the presence of dopants and melts-dissolvents is established. Influence of dispersion medium pH on the processes of embryonic iron-oxygen structures formation in the iron-carbon systems. Dependence of the nanosized embryonic iron-oxygen structures type on the dispersion medium pH value and existence form of iron cations is established for the FeO-H2O-O2 system. It is confirmed, that the rate of selective dissolving of Ag-Au initial system process is controlled by: for the chemical dealloying - the reaction products transport through the passivity film consisting of the silver compounds; for the anodic dealloying - the diffusion transport of the reaction components and products in ionic form between the initial alloy surface and the solution medium.
