It can be

It was very possible that the size of PAN chains was too large to diffuse out of the PMMA shell, thus, the

In the elastic tendons of dragonflies and locust ligaments mentioned above, it was found to have a Young’s modulus of 0.6–0.7 MPa and 0.9 MPa, respectively [11]. In addition, fully hydrated resilin can be stretched to more than three

In this particular case, the loss in sensitivity dominates and the phase values increase (see also reference [24] for a similar type of experiment on a polystyrene–polybutadiene diblock copolymer).

Thus, repulsive bimodal imaging of polymer surfaces yields a good signal quality for amplitude ratios smaller than A01/A02 = 10:1 without affecting the topography feedback.
