A method and system for carbon capture through a voltage-swing is provided. The present invention may include capturing carbon dioxide from a gas mixture through physisorption by applying a positive electrical charge to a sorbent to increase the sorbent's selectivity and adsorption and liberating the carbon dioxide from the sorbent by removing the positive electrical charge from the sorbent and applying a desorption method to the sorbent.

Voltage-swing method for carbon capture using porous carbons

A structure and method for carbon capture, e.g., in flue gas. An oxygen-terminated crown pore in graphene can be provided. Exposed carbon atoms on the pore edge can be bonded with oxygen to make a crown pore. When the COis inside the pore, the electrostatic interaction becomes attractive because the positively charged carbon atom in COis now exposed to negatively charged oxygen atoms on the crown pore edge. A favorable interaction between COand the crown pore can be expected.

A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

A compressible fluid separator pump includes a crankshaft, four cylinders, and four pistons. Each cylinder includes an inlet including an inlet valve for mixed fluid comprising a target component and a discharge component, a reject outlet including a reject valve for a reject fluid, and a select outlet for a select fluid, wherein each of the select outlets includes a separator member that prefers the target component over the discharge component such that the target component is at a higher concentration in the select fluid than in the mixed fluid and in the reject fluid. Each piston is connected to the crankshaft and is positioned in one of the four cylinders, and the crankshaft is configured to position two of the pistons at top dead center when the other two of the pistons are at bottom dead center.

A gas capture system is configured to purify gas streams. The gas capture system includes a first capture system including a plurality of first chambers interconnected by a first path. Each first chamber includes a first adsorbent. The gas capture system further includes a second capture system including a plurality of second chambers interconnected by a second path. Each second chamber includes a second adsorbent. The gas capture system further includes a third path connecting each first chamber to the second path such that a first output of the first capture system is input into the second capture system. The gas capture system further includes a fourth path connecting each second chamber to the first path such that a second output of the second capture system is input into the first capture system.

Two-system gas stream separation

A technique is provided for controlling biomolecules in a nanodevice. A membrane has two reservoirs at opposing ends of the membrane. A nanochannel is formed in the membrane connecting the two reservoirs. A gate electrode is formed on the membrane such that the gate electrode extends laterally in a region of the nanochannel. A biomolecule is trapped in the nanochannel by applying a first voltage to the gate electrode. In response to trapping the biomolecule, the biomolecule is stretched in the nanochannel by applying a second voltage to the gate electrode. The biomolecule is stretched based on changing from the first voltage to the second voltage applied to the gate electrode.

A nanosensor for detecting molecule characteristics includes a membrane having an opening configured to permit a charged carbon nanotube to pass but to block a molecule attached to the carbon nanotube. The opening is filled with an electrolytic solution. An electric field generator is configured to generate an electric field relative to the opening to drive the charged carbon nanotubes through the opening. A sensor circuit is coupled to the electric field generator to sense current changes due to charged carbon nanotubes passing into the opening, and to bias the electric field generator to determine a critical voltage related to a force of separation between the carbon nanotube and the molecule.

Nanospore sensor for detecting molecular interactions

A nanodevice includes a reservoir filled with conductive fluid and a membrane separating the reservoir. A nanopore is formed through the membrane having electrode layers separated by insulating layers. A certain electrode layer has a first type of organic coating and a pair of electrode layers has a second type. The first type of organic coating forms a motion control transient bond to a molecule in the nanopore for motion control, and the second type forms first and second transient bonds to different bonding sites of a base of the molecule. When a voltage is applied to the pair of electrode layers a tunneling current is generated by the base in the nanopore, and the tunneling current travels via the first and second transient bonds formed to be measured as a current signature for distinguishing the base. The motion control transient bond is stronger than first and second transient bonds.

Techniques for increasing the capture zone in nano and microchannel-based polymer testing structures using concentric arrangements of nanostructures, such as nanopillars are provided. In one aspect, a testing structure for testing polymers is provided that includes a first fluid reservoir and a second fluid reservoir formed in an electrically insulating substrate; at least one channel formed in the insulating substrate that interconnects the first fluid reservoir and the second fluid reservoir; and an arrangement of nanostructures within either the first fluid reservoir or the second fluid reservoir wherein the nanostructures are arranged so as to form multiple concentric circles inside either the first fluid reservoir or the second fluid reservoir with each of the concentric circles being centered at an entry point of the channel. A method of analyzing a polymer using the testing structure is also provided.

A nanopore is formed through the membrane, and the nanopore is coated with an organic compound. A first part of the organic compound binds to a surface of the nanopore and a second part of the organic compound is exposed freely inside of the nanopore. The second part of the organic compound is configured to be switched among a first neutral hydrophilic end group, a second negatively charged hydrophilic end group, and a third neutral hydrophobic end group based on a switching mechanism.

The present invention provides a nano-fluidic field effective device. The device includes a channel having a first side and a second side, a first set of electrodes adjacent to the first side, a second set of electrodes adjacent to the second side, a control unit for applying electric potentials to the electrodes and a fluid within the channel containing a charge molecule. The first set of electrodes is disposed such that application of electric potentials produces a spatially varying electric field that confines a charged molecule within a predetermined area of said channel. The second set of electrodes is disposed such that application of electric potentials relative to the electric potentials applied to the first set of electrodes creates an electric field that confines the charged molecule to an area away from the second side of the channel.
