The effect of polymer polydispersity on the fluid–fluid demixing of an athermal mixture of colloids and self-excluding polymers is analysed with the first-order thermodynamic perturbation theory (TPT1) of Wertheim. The colloidal particles and the segments making up the polymer chains are modeled as hard spheres of different diameters. The polydispersity of the polymer is represented by a distri...

Polycaprolactone (PCL) is being developed as the material of scaffolds for tissue engineering [1]. PCL is considered having fair mechanical properties and characteristics of potentials for load bearing applications, including cardiovascular, dental, and musculoskeletal [1-4]. Yet, its implementation faces some issues, e.g. inadequate mechanical properties, bioresorbability, and hydrophilicity [...

studies of three selected sulfide-silicate assemblages from ore samples from the sar cheshmeh porphyry copper deposit led to some ore genetic conclusions. the presence of chalcopyrite blebs in the groundmass orthoclase and quartz from the stock suggests liquid immiscibility in a cooling late-magmatic melt. this is in favor of the orthomagmatic model proposed for porphyry copper deposits. the pr...

The merging of immiscible drops differs significantly from the miscible due to formation a liquid–liquid interface between drops. immiscibility requires four-phase contact point, where drops, gas, and substrate meet. We show that this point has its own unique dynamics, never studied beforehand. For very different scenarios, propagation distance follows scales with time like t12. A model balanci...

The three-dimensional computer model of the Co-Cu-CoS-Cu2S subsystem T-x-y diagram at temperatures above 800?C is represented. It shown that liquid immiscibility in binary Cu-Cu2S transformed within ternary system with Co into wide two-phase region two immiscible melts, which interrupts univariant curve and Cu2S co-crystallization. special features structure solidus surface cobalt, caused by li...
