3 - You are working on an improved lightly cross-linked polyethylene (+[CH2]n-) hip replacement socket that releases a cocktail of water soluble anti-inflammatory drugs after implantation and is coated with type I collagen to allow bio-recognition and promote tissue integration. The polyethylene you are using is highly shear thinning, a necessity for the process you are using to form the socket. 1. How would you confirm the polyethylene has the correct rheology? 2. How would you quantify the components of...
