Methods, systems and devices are described for temporarily or permanently evacuating stagnating air from a diseased lung area, typically for the purpose of treating COPD. Evacuation is accomplished by displacing the stagnant CO2-rich air with a readily diffusible gas using a transluminal indwelling catheter specially configured to remain anchored in the targeted area for long term treatment without supervision. Appropriate elevated positive gas pressure in the targeted area is then regulated via the catheter and a pneumatic control unit to force under positive pressure effusion of the diffusible gas out of the area into neighboring areas while inhibiting infusion of other gases thus effecting a gradual gas volume decrease and deflation of the targeted area.

One or more external surfaces of an extruded foam are coated by co-extruding a skin of polymer on the surface to reduce the diffusion the foaming gases out of the cells of the solidifying polymer foam. The sealing effect can involve coating one side of the extruded foam (AB foam) or both sides (ABA form). The skins can be solid or foamed. Alternatively, a cylinder is formed from an annular die and, preferably, a cylindrical cooling mandrel. By extruding and drawing the cylinder of foam onto a cooled cylindrical mandrel, which expands the diameter of the cylinder, the optimum physical properties of the structure can be achieved. This is because the foam structure is stretched in longitudinal and lateral directions. Preferable, the foaming polymer has “inherent melt strength” and “strain hardening” so that the foam cells are more consistent in size and shape. The preferred polymers are polypropylene or polystyrene.

The present invention provides a method for producing an electrolytic capacitor including a porous body of a valve metal, an oxide film on a surface of the valve metal, and a conductive polymer layer on a surface of the oxide film. The step of forming the conductive polymer layer on the surface of the oxide film includes the steps of dipping the porous body in a monomer solution; lifting the porous body from the monomer solution and dipping the porous body in an oxidizing solution; and lifting the porous body from the oxidizing solution and allowing the porous body to stand. In the step of dipping the porous body in the oxidizing solution, a period for which the porous body is dipped in the oxidizing solution is equal to or shorter than a period in which 30% of the monomer contained in pores of the porous body diffuses and flows into the oxidizing solution. Alternatively, the volume of the oxidizing solution can be less than three times that of the porous body. The above method can be performed by replacing the monomer solution and the oxidizing solution with each other. Furthermore, a temperature of the porous body is maintained at a low temperature (e.g., 10 DEG C. or less) in the step of dipping the porous body in the oxidizing solution.

This invention addresses the clinical problem of how to optimize biological cell based therapies, such as stem cell therapy. Currently, cell therapies administered by intravenous, intra-arterial, and / or direct tissue injection are limited by the lack of clinically available imaging methods to detect the in vivo fate of the administered cells. There are many efforts underway to develop imaging strategies for stem cells in vivo, including radionuclide and MRI-based approaches. However, these approaches are limited by potential safety issues (e.g. radioactive exposure of stem cells, toxicity of iron particles used for MRI) and difficulty in serial tracking due to complex instrumentation and / or the requirement for repetitive radiation exposure.

A method for producing a crystalline silicoaluminophosphate (SAPO) membrane in which a porous support is contacted with SAPO seed crystals to form a SAPO seeded porous support. The SAPO seeded porous support is filled with an aqueous SAPO synthesis gel including a mixture of sources of aluminum, phosphorus, silicon, oxygen, water, and a templating agent, forming a gel-filled porous structure which is then heated to form a SAPO layer of SAPO crystals on a surface of and / or within pores of the porous support. The SAPO layer is calcined, thereby removing the templating agent and forming a supported porous SAPO membrane layer, which is then subjected to a pore size reduction post-synthesis treatment process, producing a reduced pore size supported porous SAPO membrane layer having an average pore size of less than about 0.38 nm.

The invention provides a method of making silicon-on-insulator SOI substrates with nitride buried insulator layer by implantation of molecular deuterated ammonia ions ND3+, instead of implanting nitrogen ions (N+, or N2+) as is done in prior art nitride SOI processes. The resultant structure, after annealing, has a buried insulator with a defect density which is substantially lower than in prior art nitride SOI. The deuterated nitride SOI substrates allow much better heat dissipation than SOI with a silicon dioxide buried insulator. These substrates can be used for manufacturing of high speed and high power dissipation monolithic integrated circuits.

By modifying the dielectric liner for a spacer structure so as to exhibit an enhanced diffusion blocking characteristic, for instance by incorporating nitrogen, the out-diffusion of P-dopants, such as boron, into the dielectric material may be significantly reduced. Consequently, transistor performance, especially of P-type transistors, may be significantly enhanced while nevertheless a high degree of compatibility with conventional techniques may be maintained.
