Advanced Materials Interfaces, EarlyView.By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

Advanced Materials Interfaces, EarlyView.When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Evolution of surface hardness of concrete under sulfate attack [PDF]
Construction and Building Materials, 2014 Under sulfate attack, the erosion damage is not uniformly distributed in concrete, but firstly takes place at the surface since the sulfate radical ions diffuse from surface to inner of the material.

Abstract An acoustically hard surface has reflection coefficient of +1 for all angles of incidence. A surface characterized by an impedance boundary condition, on the other hand, has a reflection coefficient which is a function of the angle of incidence. In particular, an impedance surface has a reflection coefficient of −1 at grazing
