Electroactive Polymers for Robotic Application: Artificial Muscles and Sensors
Electroactive polymers (EAPs) reply to electric stimulation with huge deformations. they're dynamic actuators that have attracted consciousness from an interdisciplinary viewers of engineers and scientists. An permitting EAP know-how is rising which makes an attempt to mimic the homes of common muscle and which, therefore, can practice a different functionality in numerous biologically-inspired robotics purposes.
Self-Organized Surfactant Structures
Highlighting contemporary advancements in addition to destiny demanding situations, this sequence of volumes covers such themes as emulsions, nano-emulsions, nano-dispersions and novel ideas for his or her research. It additionally considers the elemental procedure in parts comparable to managed liberate, drug supply and diverse purposes of nanotechnology.
Thermal Methods of Polymer Analysis
This booklet experiences a number of the thermal tools used for the characterisation of polymer houses and composition. these kind of tools examine the houses of polymers as they modify with temperature. The equipment mentioned during this publication are: differential photocalorimetry, differential scanning calorimetry, dielectric thermal research, differential thermal research, dynamic mechanical research, developed gasoline research, fuel chromatography, fuel chromatography mixed with mass spectrometry, mass spectrometry, microthermal research, thermal volatilisation, thermogravimetric research and thermomechanical research.
