Abstract: A method for identifying and removing malicious code uses a personal computing device that can communicate with a remote server. The remote server manages a blacklist and a whitelist. The blacklist is a list of programs that are known to contain malicious code. The whitelist is a list of programs that are known to be free of malicious code. The method begins when a scan request is received. The scan request is a command that directs the personal computing device to work with the remote server to perform a scan of a collection of files that will identify malicious code. The method then performs a sandboxed-evaluation process to identify files that are found to contain malicious code. The sandboxed-evaluation process is an isolated testing routine that runs program files to detect malicious code. Finally, the method executes a threat remediation process if malicious code is found.

Abstract: The present invention relates to a mesoporous monolith containing a conducting polymer such as poly(3,4-ethylenedioxythiophene) and methods for making the monolith. The mesoporous monolith is electroactive, at least semi-transparent and has one or more of a large internal pore surface area, pore size and pore volume. It can be used for various applications in photovoltaics, sensing electrochromics, separations, reversible ion exchange and control of protein activity. The method employs hydrothermal treatment and/or substantially complete drying to obtain the desirable properties of the monolith. Conducting polymer can be covalently bound to the internal pore surfaces and polymerized in situ to partially or completely fill the pores producing increased mechanical strength and a high conductivity per unit area.

Abstract: Periodic mesoporous organosilicas (PMO) which incorporate an optically active molecule into the material for use as an optical indicator of target binding. This material combines the stability, selectivity, and high density of binding sites characteristic of the PMO with the sensitivity and selectivity of the optically active molecule. The material undergoes a change when exposed to a sample containing a target molecule. The change can be observed by visual inspection or through the use of fluorescence spectra.

Abstract: A molecularly imprinted material made from polymerizing a monomer having the structural formula (OR)3Si—B-A-B—Si(OR)3. A is a divalent organic group, B is a saturated or unsaturated divalent hydrocarbon group or a covalent bond, and R is an independently selected saturated or unsaturated monovalent hydrocarbon group. A preconcentrator having: a container comprising in inlet and an outlet and the above material within the container. The inlet is capable of allowing a fluid to enter the container. The outlet is capable of being coupled to a sensor and of allowing the fluid to exit the container.

Abstract: Enzymes are modified by incorporating anchor sites for linking the enzymes to a target surface without destroying the catalytic activity of the enzymes. A stable carrier to accommodate and bind the selected enzyme is constructed, and the enzyme is non-covalently linked to the carrier, generally through metal salts of iminodiacetate.

Abstract: A method of making a molecularly imprinted porous structure makes use of a surfactant analog of the molecule to be imprinted that has the imprint molecule portion serving as the surfactant headgroup. The surfactant analog is allowed to self-assemble in a mixture to create at least one supramolecular structure having exposed imprint groups. The imprinted porous structure is formed by adding reactive monomers to the mixture and allowing the monomers to polymerize, with the supramolecular structure serving as a template. The resulting solid structure has a shape that is complementary to the shape of the supramolecular structure and has cavities that are the mirror image of the imprint group. Similarly, molecularly imprinted particles may be made by using the surfactant to create a water-in-oil microemulsion wherein the imprint groups are exposed to the water phase.

Abstract: This invention pertains to adsorption by an adsorbent of an adsorbate and to regeneration of the loaded adsorbent. The adsorption includes contacting an adsorbent selected from arylene-bridged polysilsesquioxanes and derivatives thereof with an adsorbate selected from aromatics and heterocyclics, particularly monocyclic heterocyclics containing carbon and nitrogen atoms in a 6-member non-aromatic ring, for a period of time sufficient to adsorb all or part of the adsorbate by the adsorbent. Regeneration of the loaded adsorbent includes removing all or part of adsorbate from the adsorbent by means of an alcohol wash or by thermal desorption of the adsorbent containing adsorbate.
