Methods of stabilizing the molecular weight of polymer stents scaffolds after E-beam sterilization are disclosed. The molecular weight of the polymer of the irradiated scaffolds is stabilized through exposure to gas containing oxygen.ワン,ユンビン...
Divide the molecular weight of the polymer by the molecular weight of the monomer unit to calculate the degree of polymerization. If the molecular mass of tetrafluoroethylene is 120,000, its degree of polymerization is 120,000 / 100 = 1,200. References "Chemistry: Textbook"; Raymond Chang; ...
How can the average molecular weight of this polymer be determined? There’s just one step to solve this.
However, you will need to divide the tube into smaller sections with uniform diameter and calculate the volume for each section separately before adding them together for the total volume. 5. Is the molten polymer tube model applicable to all types of polymer tubes?

(R0), then things become very easy. If you want to evaluate new solvent, you just get Hansen solubility parameter(HSP) of that solvent, and calculate HSP distance (Ra) from polymer HSP. If the distance is shorter than interaction radius (R0) then that solvent will dissolve that polymer ...
Fundamentals of Polyethylene – Part 6: PE Performance Don’t assume you know everything there is to know about PE because it’s been around so long. Here is yet another example of how the performance of PE is influenced by molecular weight and density. Read More Materials Know How 9 ...
We next asked how it is possible that long-lived misfolded proteins are able to bypass the post-translational cellular chaperone machinery. To address this question we used coarse-grained Langevin dynamics to calculate the dissociation constant between the chaperone GroEL and three distinct conformational...
One is flow induced residual stress. When in molten state, polymer molecules are unstressed, and they tend to an equilibrium, random coil state... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create...
To interpret our model, we further analyze the random forest regression results using SHAP (Shapley Additive exPlanations)35, a generalized metric for feature importance, which utilizes the game-theory-based Shapley values to calculate the contribution of each feature to the model’s output. SHAP in...
