20110186448 | DETECTION AND DISCRIMINATION OF TARGET DNA SEQUENCE AND SINGLE NUCLEOTIDE POLYMORPHISM DIRECTLY ON DOUBLE-STRANDED OLIGONUCLEOTIDE AND PCR PRODUCT WITHOUT DENATURATION OF DSDNA SAMPLE BASED ON PNA-DSDNA HYBRID AND UTILIZING PNA PROBE - A method of detection and discrimination of target DNA sequences and of single nucleotide polymorphisms (SNPs) directly on double-stranded DNA (dsDNA) samples without the need for denaturation of the target dsDNAs. This is achieved by the use of a PNA chain as a probe. This probe is self-assembled on a gold electrode; hybridization of the probe with the target dsDNA forms a PNA-dsDNA hybrid. The hybrid is then labeled with a mediator, and the PNA-dsDNA hybridization is monitored. Monitoring of the hybrid formation can be achieved using an electrochemical approach. This method is able to detect and discriminate target DNA sequences and SNPs on ds-oligonucleotides. Furthermore, this method is able to detect and discriminate target DNA sequences and SNPs on double-stranded PCR products. | 08-04-2011 |

20100210878 | Release and Recovery from Aliphatic Primary Amines or Di-Amines - There is disclosed a process for hydrogen release and chemical storage by dehydrogenating low molecular weight aliphatic amines and di-amines to produce their corresponding nitriles in a reactor system containing a hydrogen fractionation membrane (or sweep gas) to quickly remove any and all hydrogen generated during the dehydrogenation reaction. This disclosure further provides a process for hydrogen recovery using bi- and tri-functional amines that produce corresponding nitriles and high density hydrogen release. | 08-19-2010 |
20110020214 | Dehydrogenation of Cyclic Thioethers - There is disclosed a surprising reaction of an alkane thiol with a catalyst and heat to become dehydrogenated and form a thiophene rather than an expected desulfurization reaction to form the corresponding alkane or alkene. Moreover, there are disclosed surprising results regarding the form of a catalyst to allow a reaction of an alkane thiol to form the dehydrogenated thiophene at lower temperatures and at higher conversion percentages to allow for more efficient recovery of thiophenes to allow for recycling and reuse of thiophenes to hydrogenate to form alkane thiols. Further still, there is disclosed a set of reaction conditions and catalyst presentation that allows for recovery of usable diatomic hydrogen gas from a dehydrogenation reaction of substituted or unsubstituted cyclic thioethers to substituted or unsubstituted thiophene. | 01-27-2011 |
20120258020 | MICRO CHANNEL REACTOR WITH INTEGRAL HEATING ELEMENTS - In one example disclosed in the current application, by supplying just enough heat to the channel walls to replace the reaction heat removed during the reaction, a reactor exhibits tighter temperature tolerances with respect to the desired reaction temperature. In other words, the surface temperature can be more closely matched to the desired reaction temperature. Also, having a design where the channels can be scaled in both geometry and number allows control of the rate of mass transport through the channels to minimize unwanted side reactions. | 10-11-2012 |
20120282151 | REACTOR FOR REMOVAL OF HYDROGEN FROM A LIQUID ORGANIC CARRIER - The current application is directed to a packed-bed reactor comprising a housing; and section portions contained within the housing, each comprising a spiral-wound heater. The spiral-wound heaters together comprise a catalyst-disk stack. | 11-08-2012 |

20120302428 | CONTROLLED POROUS CATALYSTS TO PRODUCE HYDROGEN GAS BY DEHYDROGENATING ORGANIC COMPOUNDS - The current application discloses a method for producing a porous catalyst, the method comprising providing a powder of metal particles with a specific size; mixing into the powder of metal particles spacer spheres with a fixed diameter less than that of the metal particles; placing the metal-particle/spacing-sphere mixture in a ceramic container; heating the mixture in an oven, furnace or microwave oven to sinter the metal particles and fuse them to a solid matrix; and removing the spacing spheres either by solvolysis or pyrolysis. | 11-29-2012 |

20140134100 | HYDROGEN STORAGE SYSTEM BY CATALYTIC DEHYDROGENATION OF AMINES - The current disclosure is directed to a hydrogen-storage system that employs catalytic dehydrogenation of low-molecular-weight amines in a hydrogen reactor. The hydrogen-storage system comprises aliphatic amines and di-amines as organic carriers that store hydrogen covalently, a hydrogen reactor that releases and separates hydrogen gas from the carrier, and metal or metal-oxide catalysts that promote a dehydrogenation reaction to release hydrogen. In certain implementations, a metal or metal-oxide catalyst may be carried on high-surface-area support materials, such as gamma-alumina and metal-organic-framework materials, to enhance catalytic properties. The hydrogen reactor may be a packed-bed reactor, a monolith reactor, or a flow-through hydrogen-membrane reactor. In one implementation, the flow-through hydrogen-membrane reactor comprises an inlet through which the organic hydrogen carrier flows into the reactor, a hydrogen-separation membrane selectively permeable to hydrogen, a recirulation outlet for removing unspent organic carrier, and a hydrogen outlet for releasing hydrogen and reaction byproducts. The spent organic carrier are collected and hydrogenated to regenerate the original fuel. | 05-15-2014 |
20140187416 | PROCESSES FOR PRODUCING CONTROLLED POROUS CATALYSTS FOR THE DEHYDROGENATION OF ORGANIC COMPOUNDS - The current document is directed to processes for producing improved porous catalysts for the dehydrogenation of organic compounds. In one implementation, the process comprises providing a powder of metal particles, sieving the powder using vibrating-screen sieves, aligning metal particles collected from sieving under an external magnetic field, partially sintering the aligned metal particles to form a solid matrix by heating the aligned metal particles in a furnace or microwave oven, or heating the aligned metal particles using a laser sintering process with a controlled amount of external heat, to a temperature below the melting point of the metal powder, and oxidizing the matrix to produce the porous catalyst. The catalysts produced by the disclosed methods have a porous body with increased surface area, can assume various microstructures, and consist essentially of metal oxides. | 07-03-2014 |
