A method for continuously separating components from a sample includes providing a field-flow fractionation device including: a channel coupled to a flow generator for translocating the sample components along the channel in a first direction, an actuator for translocating the sample components in a second direction, at an angle with the first direction, and an array of electrodes electrically or capacitively connected to an AC power source, operating the actuator so as to translocate the sample components in a second direction at an angle with the first direction, operating the AC power source so as to generate an AC electric field between adjacent rows, and operating the flow generator, collecting sample components from the sample outlets.

A microfluidic device can include a base an outer surface of which forms one or more enclosures for containing a fluidic medium. The base can include an array of individually controllable transistor structures each of which can comprise both a lateral transistor and a vertical transistor. The transistor structures can be light activated, and the lateral and vertical transistors can thus be photo transistors. Each transistor structure can be activated to create a temporary electrical connection from a region of the outer surface of the base (and thus fluidic medium in the enclosure) to a common electrical conductor. The temporary electrical connection can induce a localized electrokinetic force generally at the region, which can be sufficiently strong to move a nearby micro-object in the enclosure.

The present disclosure describes methods, devices and systems comprising materials comprising dielectrics.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.
