Publication number: 20130116111Abstract: Preparation of a molecularly imprinted carbon is described. The molecularly imprinted carbon has a surface that is imprinted on the molecular level for a specific template molecule of interest, making it highly selective for analytes corresponding to at least a portion of the template molecule. Devices including the molecularly imprinted carbon and their use in methods of detecting analytes are also described. As an example, dibutyl butylphosphonate (DBBP), a surrogate for chemical warfare agents, was used as a template molecule. Electrospun molecularly imprinted SU-8 and pyrolyzed polymer (PP) solid-phase microextraction (SPME) devices were prepared; their ability to preferentially extract DBBP from an aqueous matrix, with and without interferences present, was evaluated via comparison with non-imprinted SU-8 and PP SPME fibers. The electrospun devices demonstrated a higher selectivity for DBBP, as evidenced by their extraction time profiles.Type: ApplicationFiled: March 2, 2011Publication date: May 9, 2013Applicant: The Ohio State University Research FoundationInventors: Susan V.

Patent number: 8377310Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.Type: GrantFiled: May 11, 2010Date of Patent: February 19, 2013Assignee: J.I.

Patent number: 8076034Abstract: A high pressure hydrogen confinement apparatus according to one embodiment includes carbon nanotubes capped at one or both ends thereof with a hydrogen-permeable membrane to enable the high pressure confinement of hydrogen and release of the hydrogen therethrough. A hydrogen confinement apparatus according to another embodiment includes an array of multi-walled carbon nanotubes each having first and second ends, the second ends being capped with palladium (Pd) to enable the high pressure confinement of hydrogen and release of the hydrogen therethrough as a function of palladium temperature, wherein the array of carbon nanotubes is capable of storing hydrogen gas at a pressure of at least 1 GPa for greater than 24 hours. Additional apparatuses and methods are also presented.Type: GrantFiled: September 18, 2008Date of Patent: December 13, 2011Assignee: Lawrence Livermore National Security, LLCInventors: David H. Lassila, Brian P. Bonner
