P7. Thinking of the case of the hydrogel used as the absorbing element in diapers, how would you balance absorbance capacity of the beads with mechanical strength of the beads?

P8. You are tasked with the design of a new polymeric mesh system to treat skin burns while delivering a regenerative drug. What type of polymer would you select for such application? Provide a rationale for your choice and 2-3 different compositions.

P9. You are given two polymer samples and are tasked with the design of a mechanical testing protocol to figure out basic material properties. Sample (A) is a crystalline polymer with Tm>100oC, sample B is an amorphous polymer with Tg = 20oC. Making the necessary assumptions, explain how you would conduct mechanical testing for each case.
