20090131643 | Rapid metal organic framework molecule synthesis method - A rapid, simple and versatile metal organic framework molecule (MOF) synthesis method particularly adapted to make non-linear MOFs includes heating MOF precursors, such as a metal or metal oxide and an organic ligand, in a microwave oven for a period sufficient to achieve crystallization. Microwave-assisted MOF synthesis yields high quality MOF crystals in a reaction time ranging from about 5 seconds to about 2.5 minutes, compared to hours and days required in conventional solvothermal and hydrothermal methods. In addition, microwave assisted methods provide MOF materials with uniform crystal size and well-defined shape. Further, microwave synthesis of MOFs allows the size and shape of MOF crystals to be tailored for use in a wide range applications by manipulating reaction conditions. Secondary growth processes may also be employed to grow larger crystals using seeds obtained from microwave-assisted synthesis methods. | 05-21-2009 |
20100132547 | HIGH GAIN SELECTIVE METAL ORGANIC FRAMEWORK PRECONCENTRATORS - Novel metal organic framework (MOF) molecules and methods of synthesizing them are described. MOFs are organometallic crystalline structures that have high sorption capacity due to high surface area, tailorable selectivity, an inert nature, and thermal stability at high temperatures. MOFs may be used as sorbents in preconcentrators for analytical devices to provide orders of magnitude of improved sensitivity in analyte detection. MOFs are also useful as sorbents in new compact and portable micropreconcentrator designs such as a modified purge and trap system and a multi-valve microelectromechanical system (MEMS) to achieve high gain in analyte detection. Further, MOFs may be used as coatings for novel microstructure arrays in micropreconcentrators where the microstructures are designed to increase the surface area to volume ratio inside the micropreconcentrator while minimizing the pressure drop across the micropreconcentrator. | 06-03-2010 |

20100075123 | WATER REPELLENT METAL-ORGANIC FRAMEWORKS, PROCESS FOR MAKING AND USES REGARDING SAME - Microwave assisted synthesis may be used to produce water-repellent metallic organic frameworks (MOFs) molecules. The water-repellent MOFs contain non-polar functional groups, such as a trifluoromethoxy group, which has a strong water repellent effect. The water-repellent MOF, when exposed to water vapor for one week does not result in a significant X-ray power pattern change. The water-repellent MOFs may be suitable as an adsorbent in many industrial applications, such as gas chromatography. | 03-25-2010 |

20110249954 | CAPTURING PRESENTATIONS IN ONLINE CONFERENCES - Presentations during an online conference are captured for subsequent playback. An instance of a presentation viewer is deployed to capture the presentation. Annotations and timing data are captured separately. The presentation with the annotations is recorded through a video encoding codec in a desired format, while timing and similar data is stored as metadata. Multiple presentations may be recorded separately to conserve resources. The recordation and the metadata can be subsequently played back to a requesting user. | 10-13-2011 |
