    Introduction: At present, the polymer gel dosimeter is considered to be the best possible dosimeter for measuring 3-dimesional radiation dose distribution in radiotherapy. These gels are normally toxic; therefore, manufacturing, handling and discarding them require special attention. In order to...

    The rheology of dense colloidal suspensions is sensitive to modifications in the surface properties of the particles. We are using lattice Boltzmann simulations to investigate the effects of polymer coatings on the squeezing flow between parallel plates. In this study, we used random arrays of...

    We describe a new type of electroactive polymer gel. In contrast to cross-linked polyacrylates, this system is based on triepoxides cross-linked with polyfunctional amines. The stoichiometry is selected to form a cross-linked gel with excess amino hydrogens. In acid solutions these become...

    We examine the effect of a dynamic stress on the reduction of flow in porous media using polymer gels formed in situ. To develop the theory for the response of the gel, we consider three dominant factors: (a) compressive (elastic) deformation of the gel and porous medium, (b) microscopic flow in...
