Modeling of biological objects on the basis of computer and magnetic resonance imaging is a common practice today. DICOM source files (CT with contrast agent, heart without pathologies) were obtained at the Saratov cardiology center and correspond to diastole of cardiac cycle. The created geometric model consists of the internal volume of blood, ventricles, atria, heart valves and tendon chords. The resulting model can be studied using various computer systems, in particular, the finite element method.
Last times carbon nanostructures based on carbon nanotubes and graphene are actively used in different fields of science and technic. Main problem of using these carbon nanostructures in water environment is that carbon nanostructures have a tendency to bond with each other via Van-der-Waals interaction. This issue can be resolved by the appending surface-active materials, such as phospholipids, into composite. We have carried out research on influence of phospholipids on stability of carbon composite. This researching was carried out by the increasing of the number of the phospholipids in the structure. Numerical counts were carried out on minimal structure cell of composite using AMBER energy potential with Berenson thermostat. Its concluded that stable of composite decreases by the increasing of number of the phospholipids.
