  • Patent number: 9446348
    Abstract: The present invention provides gels, solutions, films, membranes, compositions, and other materials containing polymerized and/or non-polymerized room-temperature ionic liquids (RTILs). These materials are useful in catalysis, gas separation and as antistatic agents. The RTILs are preferably imidazolium-based RTILs which are optionally substituted, such as with one or more hydroxyl groups. Optionally, the materials of the present invention are composite materials comprising both polymerized and non-polymerized RTILs. The RTIL polymer is formed from polymerized RTIL cations typically synthesized as monomers and polymerized in the presence of the non-polymerized RTIL cations to provide a solid composite material. The non-polymerized RTIL cations are not covalently bound to the cationic polymer but remain as free cations within the composite material able to associate with charged subunits of the polymer. These composite materials are useful in catalysis, gas separation, and antistatic applications.

  • Publication number: 20150258273
    Abstract: Electrochemical actuation is disclosed for fluid movement and flow control in microfluidic devices, allowing for miniaturization, minimal power requirements, single-use disposability and engineering of small, complex fluidic networks. In one embodiment, a single-dose fluid delivery device is operable to deliver a bolus dose, in a single extended stroke or in multiple repeated doses. The device uses three electrochemically-actuated chambers, two of the chambers operating as inlet/outlet valves for the device and a third providing both a temporary containment and pumping action. By sequential manipulation of the fluid pressure in the three chambers, fluids may be delivered in precise quantities by the device.

  • Publication number: 20140352533
    Abstract: The invention provides methods for making silicoaluminophosphate-34 (SAPO-34) membranes comprising interlocking SAPO-34 crystals. In the methods of the invention, the SAPO-34 membranes are formed through in situ crystallization on a porous support using a synthesis mixture initially including a SAPO-34 forming gel and a plurality of SAPO-34 crystals dispersed in the gel. The invention also provides supported SAPO-34 membranes made by the methods of the invention. The invention also provides methods for separating a first gas component from a gas mixture, the methods comprising the step of providing a membrane of the invention.

  • Publication number: 20140154499
    Abstract: A method of forming a nanoporous membrane includes preparing a solution of a gemini Imidazolium Lyotropic Liquid Crystal (LLC) monomer, a polar low-volatility organic solvent, and a radical photo-initiator in a volatile organic solvent; solvent-casting the solution onto a porous material, evaporating the volatile organic solvent; heating such that the gemini imidazolium monomer forms a Q-phase material and photopolymerizing the imidazolium monomer by exposing the radical photo-initiator to UV light; and exchanging the polar low-volatility organic solvent. Also disclosed is a membrane composed of polymerized gemini imidazolium LLC monomers, and a thin-film composite membrane having the Q-phase material supported on a porous supporting membrane.

  • Patent number: 8679227
    Abstract: The present invention provides methods for making improved zeolite and crystalline silicoaluminophosphate (SAPO) membranes, in particular SAPO-34 membranes, on a porous support through improved removal of the organic structure-directing templating agent. A calcining step is performed in an oxygen free atmosphere, such as under a vacuum or inert gas, to remove the organic templating agent. By removing the templating agent in the absence of oxygen, the calcination step can remove a greater amount of the templating agent than comparable template removal steps conducted in the presence of oxygen and the calcination step can be conducted at significantly lower temperatures. The membranes of the present invention provide increased permeance while maintaining comparable selectivity for gas separations, particularly carbon dioxide (CO2) and methane (CH4) separations and separations at high temperatures.

  • Patent number: 8409326
    Abstract: SAPO-34 membranes and methods for their preparation and use are described. The SAPO-34 membranes are prepared by contacting at least one surface of a porous membrane support with a synthesis gel. The Si/Al ratio of the synthesis gel can be from 0.3 to 0.15. SAPO-34 crystals are optionally applied to the surface of the support prior to synthesis. A layer of SAPO-34 crystals is formed on at least one surface of the support. SAPO-34 crystals may also form in the pores of the support. SAPO-34 membranes of the invention can have improved selectivity for certain gas mixtures, including mixtures of carbon dioxide and methane.

  • Patent number: 8343324
    Abstract: The invention provides electrochemically-based methods and devices for producing fluid flow and/or changes in fluid pressure. In the methods and devices of the invention, current is passed through a divided electrochemical cell. Adjacent compartments of the cell are divided by a separator which comprises an ionically conducting separator. Each compartment includes an electrode and an electrolyte solution or ionic liquid. The electrolyte solution(s) or ionic liquid(s) and the ionically conducting separator are selected to obtain the desired relationship between the current through the cell and the fluid flowrate and/or change in fluid pressure.

  • Patent number: 8302782
    Abstract: SAPO-34 membranes and methods for their preparation and use are described. The SAPO-34 membranes are prepared by contacting at least one surface of a porous membrane support with a synthesis gel comprising a first and a second templating agent. SAPO-34 crystals having a narrow size distribution were applied to the surface of the support prior to synthesis. A layer of SAPO-34 crystals is formed on at least one surface of the support. SAPO-34 membranes of the invention can have improved selectivity for certain gas mixtures, including mixtures of carbon dioxide and methane.
