摘要:
Substantially pure oxygen is provided to an up flow reformer (49a) from a separator (108) downwardly impelled water droplets (53) mix with the outflow (58) of a CPO (59), flowing upwardly through high temperature (68) and low temperature (73) water gas shift reactors. The reformer output flows through a mixer (79) to a down-flow PrOx containing two beds (82, 94) of preferential CO oxidation catalyst therein. A series of compressors (120-122) compress water and carbon dioxide out of the gaseous flow to provide pure, pressurized hydrogen. Oxygen (111) is separated (105, 108) from nitrogen (112).

A fuel processing system (FPS) (120, 220, 320) provides a hydrogen-rich reformate having a reduced level of CO (34, 234, 62), as for use in a fuel cell power plant (120). The FPS includes, in combination, a reformer (30, 230) for converting hydrocarbon feedstock (22) to reformate and a multistage hybrid WGS reactor (150, 250, 350) for converting CO with H2O in the reformate to H2 and CO2 to reduce the CO in the reformate. The multistage hybrid WGS reactor (150, 250, 350) has one stage (154, 254, 352) of active noble metal catalyst (174, 274, 374), typically platinum and/or rhenium, and an other stage (152, 252, 354) of Cu-based WGS catalyst (172, 272, 372), e.g. Cu/ZnO, whereby the collective volume of the one and the other stages is relatively small, being less than about ½ that of prior WGS reactors. The Cu-based WGS catalyst may be modified to reduce self-heat. Protection from sulfur in the reformate is also provided. The multistage hybrid WGS reactor (150, 250, 350) may further include an O2 guard.

摘要:
The present invention relates to a device for preparing assay samples using a number of microscope slides. Each slide has a number of assay reaction surface locations spaced on the planar surface of the slide. In preferred embodiments, the device comprises, in part, a microscope slide holder that has the exterior dimensions of a SBS standard microplate, such as a 96 well plate. The device accepts conventional microscope slides equipped with sixteen microarray surfaces spaced nine millimeters apart on center, or four for a 96 well plate. Individual chamber plates are placed on top of the slides, creating an individual well above each assay reaction surface location. In preferred embodiments, each assay reaction surface location can comprise a microarray of multiple reactive sites. Thus, parallel processing can be done of samples for genomic or proteomic profiling. An advantage of the present invention is that one can use the conventional high throughput assaying equipment for SBS standard microplates while using conventional microscope slides, thereby allowing the use of robotic assay reading equipment designed for slides.
摘要:
Oxides of nitrogen are adsorbed onto the surfaces of, and particulates are trapped in, pores of channels (130, 133, 139-151) in a porous, interdigitated ceramic particulate filter (57, 100) that has relative rotation with respect to a gas inlet distributor (76, 101). The distributor has a baffle (85) or ribs (121, 122) that causes constantly flowing engine exhaust (53) to enter the filter channels over a large portion of a revolution of the adsorption bed or the distributor, and causes constantly flowing syngas (54) to thereafter pass through those passages during a small portion of each revolution. Either the inlet gas distributor (101) or the filter bed (57) may be rotated to distribute the gases. Dual, alternately regenerated filters (35, 36) may be used.

摘要:
The present invention relates to a novel amphiphilic block copolymer and the preparation method thereof, as well as a micellar drug-loaded system formed by said copolymer and an anti-tumor drug. Said amphiphilic block copolymer comprises a hydrophilic segment and a hydrophobic segment, and the end group of said hydrophobic segment is end-capped with a hydrophobic group. Methoxypolyethylene glycol (or polyethylene glycol)-polyester block copolymer which has recognized safety is used as a fundamental material of the amphiphilic block copolymer of the present invention, and the terminal hydroxyl group of the polyester segment is modified with a hydrophobic group, whereby the compatibility between the drug molecule and the hydrophobic segments of the block copolymer is improved, and the interaction therebetween is enhanced. Moreover, a larger space for accommodating the drug molecules is provided. Said micelles are more effective in restricting the drug molecules inside the micellar core and preventing the drug from dissolved out of the micelles. Therefore, a drug-loaded micelle with high stability is obtained.

A page-turning method for reading an MMS message in a mobile phone is disclosed herein, and comprising steps: A. enter the MMS message and turn to a first page; B. detect an operating command to determine an operating type, enter step C if it is a page-turning operation, enter step D if it is a page designating operation; C. execute the corresponding operating command to turn to a next or previous page according to the page-turning operation; and D. execute the corresponding operating command to turn the MMS message to a designated page according to the page designating operation. The method described above can help the user determine the type of the page-turning operation and provides two page-turning operations (a page-turning operation and a page designating operation), so the user can turn the MMS message arbitrarily to the page, and thereby conveniently enter to read the MMS message.
