Shape memory alloys, materials capable of being deformed and maintaining the deformation additionally returning to initial position, are valued for a range applications from actuators flexible microdevices. Maintaining properties that make them useful, their ability deform reform, requires shape alloys must be protected against corrosion, in which integration polymers can act as means protectio...

The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...

Let us see how this contrasts with the standard foundations for geometry that have existed for almost three thousand years. In the standard foundations, a geometric object consists of those properties of a figure that do not change under a set of actions. These properties are called the invariants of the actions. Geometry began with the study of invariance, in the form of Euclid’s concern with ...
