Experimental Studies and Numerical Simulation of Polypyrrole Trilayer Actuators

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Polypyrrole Soft Actuators

Soft, flexible micromanipulators comprising polypyrrole trilayer microactuators

Within the areas of cell biology, biomedicine and minimal invasive surgery, there is a need for soft, flexible and dextrous biocompatible manipulators for handling biological objects, such as single cells and tissues. Present day technologies are based on simple suction using micropipettes for grasping objects. The micropipettes lack the possibility of accurate force control, nor are they soft ...

4th World Congress on Biomimetic, Artificial Muscles and Nano-Bio Life Time of Trilayer Actuators Based on Polypyrrole

Artificial muscles based on polypyrrole films doped with ClO4 had demonstrated movements up to 180 degrees in LiClO4 aqueous solution which are controlled through the applied electrical current. Movements of this type are achieved with currents from 10 mA. The current density and its polarity control the rate and the movement ́s direction of the artificial muscle[1, 2]. Besides, bilayer and tril...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
