Electromotive Force in Electrochemical Modification of Mudstone

Osmotic Engine: Translating Osmotic Pressure into Macroscopic Mechanical Force via Poly(Acrylic Acid) Based Hydrogels

Poly(acrylic acid)-based hydrogels can swell up to 100-1000 times their own weight in desalinated water due to osmotic forces. As the swelling is about a factor of 2-12 lower in seawater-like saline solutions (4.3 wt% NaCl) than in deionized water, cyclic swelling, and shrinking can potentially be used to move a piston in an osmotic motor. Consequently, chemical energy is translated into mechan...

Electric Currents, Membranes, and Biological Sources of Electromotive Force **

A description of steady-state material transfer through the barrier of the idealized physiological transfer unit, phase 1, membrane, phase 2,-two homogeneous phases separated by a complex barrier-based upon Newton's laws of motion has been outlined previously.1 The supposition was made that the conservative forces tending to drive the kinetic materials through a barrier b can be derived from di...

The Electromotive Force Produced by the Acceleration of Metals.

mecum, and the cutting is due to constriction in this ring, and the constriction to a change in surface tension, the work invo ved would require a minimum reduction along the inner surface of the ring of at least 383 dynes per centimeter. The bulk of evidence at hand seems to indicate that the paramecia are divided by the approach of two pseudopods and not by the constriction of a ring. To acco...

Universal electromotive force induced by domain wall motion.

The electromotive force induced by a moving magnetic domain wall in a nanostrip has been calculated theoretically and detected experimentally. It is found that the emf depends only on the domain wall transformation frequency through a universal Josephson type relation, which is closely related to the topological nature of the domain wall. Our experimental measurements confirm the theoretical pr...
