Publication number: 20110175035Abstract: The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or ?-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state.Type: ApplicationFiled: April 1, 2011Publication date: July 21, 2011Applicant: Massachusetts Institute of TechnologyInventors: Timothy M. Swager, Jye-Shane Yang, Vance Williams, Yi-Jun Miao, Claus G. Lugmair, Igor A. Levitsky, Jinsang Kim, Robert Deans

Patent number: 7754910Abstract: A process for the ammoxidation of a saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon to produce an unsaturated nitrile, said process comprising contacting the saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon with ammonia and an oxygen-containing gas in the presence of a catalyst composition comprising molybdenum, vanadium, antimony, niobium, tellurium, optionally at least one element select from the group consisting of titanium, tin, germanium, zirconium, hafnium, and optionally at least one lanthanide selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. Such catalysts are characterized by very low levels of tellurium in the composition. Such catalyst compositions are effective for the gas-phase conversion of propane to acrylonitrile and isobutane to methacrylonitrile (via ammoxidation).Type: GrantFiled: January 29, 2008Date of Patent: July 13, 2010Assignee: Ineos USA LLCInventors: Claus G.

Patent number: 7134459Abstract: Method for preparing a mixed powder sample by mixing two or more different powders comprising transferring a quantity of a first powder to a mixing vessel and transferring a quantity of a second powder to the mixing vessel to form a powder bed in the mixing vessel comprising the first and second powders. The quantities of the powders are selected so the mixed sample has a predetermined ratio of first powder to second powder. The powder bed is fluidized to mix the powders and produce a mixed sample. The mixed sample weighs about 5 grams or less. The invention also includes apparatus for preparing mixed powder samples by mixing two or more different powders.Type: GrantFiled: June 3, 2004Date of Patent: November 14, 2006Assignee: Symyx Technologies, Inc.Inventors: Eric Carlson, Li Song, Daniel M.

Patent number: 6805175Abstract: Apparatus for aspirating and dispensing powder, comprising a hopper having a powder transfer port and a suction port for connection to a source of suction to establish an upward flow of air (or other gas) through the transfer port. A gas flow control system varies the upward flow through the transfer port to have different velocities greater than 0.0 m/s. These velocities include an aspirating velocity for aspirating powder into the hopper through the transfer port to form a fluidized bed of powder in the hopper, and a dispensing velocity less than the aspirating velocity but sufficient to maintain fluidization of the bed while allowing powder from the bed to gravitate through the transfer port for dispensing into one or more destination receptacles. A method of aspirating and dispensing powder is also disclosed.Type: GrantFiled: June 12, 2003Date of Patent: October 19, 2004Assignee: Symyx Technologies, Inc.Inventors: Daniel M. Pinkas, Claus G.
