A macroscopic theory for surface segregation in and copolymers and polyblendsIn this work, the gradient theory was used to explain and correlate some of the phenomena observed for polymer surface segregation....
Influence of bulk concentration on the discontinuous transition in surface segregationAbstract: The discontinuous transition of surface concentration due to the change of bulk concentration in isosteric/isothermal surface segregation has been discussed quantitatively according to the modified Darken model....
Surface segregation in supported pd-pt nanoclusters and alloysSurface segregation processes in Pd-Pt alloys and bimetallic Pd-Pt nanoclusters on alumina and carbon supports (technical catalysts) have been investigated by determining the ...
Quantum chemistry for surface segregation in metal alloys... A phenomenon that occurs in alloys that does not arise in pure metals is surface segregation, where the composition of the surface differs from the bulk composition....
