Eco conscious synthesis of poly(tetramethylene itaconate) emphasizing inhibitor free and solvent free sustainability

open access: yesScientific Reports
Artificial tissues and organs can be obtained through a modern material processing method − 3D printing. In this method, 3D printing inks are used. Those are most commonly made of polyacrylates which show several undesirable characteristics.

Role of solvent for globular proteins in solution

open access: yes, 2005
The properties of the solvent affect the behavior of the solution. We propose a model that accounts for the contribution of the solvent free energy to the free energy of globular proteins in solution.
