A collaborative client-server system having performance reliability improvement (PRIM) includes collaboration techniques for sharing server data among two or more servers, each server coupled to one or more client computers. A communication link between a client computer and a server is handed off to another respective one of the two or more servers under a variety of conditions. Hand off conditions include, congestion of the server processing load, congestion of the communication link between the client computer and the server, and loss of data signal integrity between the client computer and the server.

The present invention discloses a relatively simple CVD method for forming specifically tailored carbon-based nanostructures. In general, the method is a chemical vapor deposition method in which at least a portion of the precursor materials are provided as a liquid at atmospheric conditions. The precursor materials include at least one carbon source and at least one catalyst source. Optionally, the precursor materials can also include one or more dopant sources. The carbon source and the optional dopant source can be injected as liquids into the system, and the liquid catalyst source can be either injected into the system or located on a substrate in the reactor prior to the process. Very high yield of nanostructures exhibiting particular characteristics can be attained by the process. Control of electrical characteristics as well as structural characteristics of the products are possible via control of process parameters including the particular precursors used as well as the relative amounts of the precursors used.

This invention relates to the development of a new Raman enhancing reagent and a surface-enhanced Raman scattering (SERS) method for rapid and ultra-sensitive detection and identification of perchlorate (ClO) and other anions such as technetium (TcO), uranium and nitrate in environmental samples. The method involves the synthesis of controlled gold nanoparticles which are modified with amine functional groups such as 2-(dimethylamino)ethanethiol and N,N,N-trimethylaminethiol. These functionalized Au nanoparticles were found to be reactive with perchlorate and other anions and can be used to detect these anions by Raman spectroscopy at ultra low concentrations in complex environmental matrices. This invention overcomes the limitations of currently-available analytical techniques by offering an inexpensive, rapid, ultra-sensitive, and real-time identification and detection of perchlorate and other anions. The technique is not only sensitive but also highly specific because of the unique Raman vibrational bands of perchlorate and other anions.

Anchored nanostructure materials and methods for their fabrication are described. The anchored nanostructure materials may utilize nano-catalysts that include powder-based or solid-based support materials. The support material may comprise metal, such as NiAl, ceramic, a cermet, or silicon or other metalloid. Typically, nanoparticles are disposed adjacent a surface of the support material. Nanostructures may be formed as anchored to nanoparticles that are adjacent the surface of the support material by heating the nano-catalysts and then exposing the nano-catalysts to an organic vapor. The nanostructures are typically single wall or multi-wall carbon nanotubes.

Methods of fabricating nano-catalysts are described. In some embodiments the nano-catalyst is formed from a powder-based substrate material and is some embodiments the nano-catalyst is formed from a solid-based substrate material. In some embodiments the substrate material may include metal, ceramic, or silicon or another metalloid. The nano-catalysts typically have metal nanoparticles disposed adjacent the surface of the substrate material. The methods typically include functionalizing the surface of the substrate material with a chelating agent, such as a chemical having dissociated carboxyl functional groups (—COO), that provides an enhanced affinity for metal ions. The functionalized substrate surface may then be exposed to a chemical solution that contains metal ions. The metal ions are then bound to the substrate material and may then be reduced, such as by a stream of gas that includes hydrogen, to form metal nanoparticles adjacent the surface of the substrate.

Techniques for modeling living biological systems include receiving constant values for multiple interaction factors w. A set of initial state values is received for state variables that indicate relevant properties of a living biological system. Also received is a set of trial values for perturbation variables that indicate factors that might affect one or more of the relevant properties of the biological system. A temporal change in a value for a particular state variable is determined based on a non-linear transformation of a sum of the trial value for the perturbation that affects the particular state added to a sum of all non-zero values for a product of wand a state variable over all state variables. In some embodiments, measurement-based values are received for a measurable subset of the state variables. Values for the constant interaction factors ware determined based on the measurement-based values.

Methods for fabricating anchored nanostructure materials are described. The methods include heating a nano-catalyst under a protective atmosphere to a temperature ranging from about 450 C. to about 1500 C. and contacting the heated nano-catalysts with an organic vapor to affix carbon nanostructures to the nano-catalysts and form the anchored nanostructure material.

A fluffy nano-material and method of manufacture are described. At 2000× magnification the fluffy nanomaterial has the appearance of raw, uncarded wool, with individual fiber lengths ranging from approximately four microns to twenty microns. Powder-based nanocatalysts are dispersed in the fluffy nanomaterial. The production of fluffy nanomaterial typically involves flowing about 125 cc/min of organic vapor at a pressure of about 400 torr over powder-based nano-catalysts for a period of time that may range from approximately thirty minutes to twenty-four hours.
