The Russian Science Foundation (RSF) has summed up the results of the 2021 competition for grants in the priority area of activity of RSF "Conducting fundamental scientific research and exploratory scientific research by small individual scientific groups". The project of Timofey Krit " Mechanical elasticity of tissue-like materials for tissue engineering" is supported. The project is aimed at solving the scientific problem of establishing the relationship between rheological parameters and characteristics of shear waves in viscoelastic media such as hydrogels. The relaxation times of hydrogels determine the frequency dependencies of the velocity and attenuation time of shear waves. The problem has become relevant in connection with the development of tissue engineering methods. Hydrogels are used as matrices for tissue engineering. The measurement of the viscoelastic properties of hydrogels and the creation of adequate models of these materials is therefore an important practical problem. The main objective of the project is the development of techniques and the study of rheological parameters (relaxation times) in viscoelastic media such as hydrogels. The solution to this problem will make it possible to correctly predict the response of hydrogels to impulse mechanical effects. The fundamental significance of this research is the creation of physical models that will lead to the further development of ideas about the viscoelastic properties of gel-like media. Congratulations to Timofey and the whole LIMU team with a new grant!
