Micromachined Shape-Memory-Alloy Microactuators and Their Application in Biomedical Devices

open access: yesMicromachines, 2015
Shape memory alloys (SMAs) are a class of smart materials characterized by shape memory effect and pseudo-elastic behavior. They have the capability to retain their original form when subjected to certain stimuli, such as heat or a magnetic field.

Toughening mechanisms in novel nano-silica epoxy polymers [PDF]

open access: yes, 2007
A crosslinked epoxy polymer has been modified by the addition of nano-silica particles. The particles were introduced via a sol-gel technique which gave a very well dispersed phase of nanosilica particles which were about 20 nm in diameter.
