摘要
An insight into the molecular assembly processes that lead ultimately to the gelation of water by small organic molecules can be gained by the combination of two powerful techniques. Vitrified ice cryo-transmission electron microscopy (TEM) (see Figure) and X-ray diffraction. have been applied to evaluate the nanoscale structure and molecular organization of an organic hydrogel in its native (hydrated) state.
