We leverage the phase segregated microstructure of polyurea to study its shock response using molecular dynamics (MD) simulation. The two domains, hard and soft are investigated separately. domains is studied a multiscale shock-simulation approach that allows simulation low pressure shocks. Both exhibit an unconventional behavior at velocities typically associated with polymers. domain marked b...

statement of problem: despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. purpose: the aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. materials ...
