Abstract: Immobilized nitronyl nitroxide active sites on the surface of a porous inorganic oxide support act as efficient and rapid oxidants for NO, reacting with >99% of the NO under flow conditions through a packed bed; and, in a parallel configuration with nitroxyl radical active sites, act to remove >99 % of both NO and NO2 from a gas mixture, with >95% of the active sites participating in NOx trapping.

Abstract: Immobilized calixarenes and calixarene-related compounds are produced by a process comprising either: (a) contacting the calixarene or calixarene-related compound with a substrate containing one or more metallic or non-metallic oxides that has been surface modified by reaction with one or more polyhalides and/or polyalkoxides of an element capable of forming a stable aryloxide species with the substrate, or (b) reaction of such a substrate with a calixarene or calixarene-related compound that has been previously modified or derivatized by reaction with said polyhalides and/or polyalkoxides.

Abstract: Inorganic oxides, particularly silica or germania or inorganic oxides containing silica and/or germania, are imprinted with one or a plurality of functional moieties such as amine and/or thiol groups by a process featuring incorporating such groups into the oxide by use of a thermally labile material containing a protecting group for the amine or thiol, followed by removal of the thermally labile moiety by thermolysis. The resulting products are inorganic oxide substrates or bulk inorganic oxides imprinted with the functional moieties. A plurality of such moieties may be imprinted on a substrate in an order fashion using a polymeric imprinting compound, and may then be used as a templated array of functional moieties to which ordered metallic nanostructures may be constructed.

Abstract: The present invention relates to amorphous inorganic materials having pores of controlled size and shape with one or more spatially organized functional groups formed therein. Much like the active site residues in an enzyme, these functional groups can be positioned in a defined three dimensional relationship within the voids and with respect to each other. By varying both the positions and identities of these functional groups, diverse sets of substrate specific adsorbents and non-biologically-based catalysts can be made.

Abstract: An improved self-contained portable lighting system comprising: a first shell having an interior portion in which lights are mounted and having an exterior portion on which is mounted a first closure; a plurality of reflectors are mounted by hinges on edges of a front face of the interior portion of the first shell so that the reflectors may be folded on top of one another and substantially flat against the interior portion of the first shell; a second shell having an exterior portion including second closure for engaging the first closure and locking the first shell the said second shell together.

Abstract: A method using quartz resonators probes dynamically the mechanical characteristics of thin films. This method probes the film properties at the anti-resonance frequency where the vibrational amplitude is smallest, minimizing nonlinear contributions in the dependence of the film mechanical characteristics on the resonator electrical characteristics. Determination of the mechanical characteristics involves impedance analysis, transformation of .vertline.Y.vertline. and .theta. data into a linear form so that the conductance and susceptance at the frequency of minimum absolute admittance can be accurately determined, and use of a two-dimensional Newton-Raphson numerical method to determine the values of the storage modulus G', loss modulus G", as well as various other film and resonator properties.
