Analysis of electroosmotic dewatering at constant voltage.

Electroosmotic dewatering of dredged sediments: bench-scale investigation.

The Indiana Harbor (Indiana, USA) has not been dredged since 1972 due to lack of a suitable disposal site for dredged sediment. As a result of this, over a million cubic yards of highly contaminated sediment has accumulated in the harbor. Recently, the United States Army Corps of Engineers (USACE) has selected a site for the confined disposal facility (CDF) and is in the process of designing it...

Low frequency voltage clamp: recording of voltage transients at constant average command voltage.

We implemented a simple feedback system that modifies the conventional current clamp mode of a patch clamp amplifier so that transient potentials, such as action potentials and synaptic potentials, can be measured as in the usual current clamp, while the average membrane potential is kept constant at a value chosen by the user. The circuit thus works like the current clamp for high frequency si...

Constant Voltage Contact Surface

LIDAR (laser radar) is used to measure three-dimensional(3-D) object positions. It produces a range and an intensity image ofthe measured object and relieson the range image to determine the 3-Dpositions of the object. But, the range image is frequently corrupted withnoise. A dynamic calibration method has been established to improvethe LIDAR accuracy basedon a polyn...

Low-voltage electroosmotic pumps fabricated from track-etched polymer membranes.

Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...
