Single-molecule selection methods are provided for identifying target-binding molecules from diverse sequence and shape libraries. Complexes and imprints of selected target-binding molecules are also provided. The subject selection methods are used to identify oligonucleotide and nonnucleotide molecules with desirable properties for use in pharmaceuticals, drug discovery, drug delivery, diagnostics, medical devices, cosmetics, agriculture, environmental remediation, smart materials, packaging, microelectronics and nanofabrication. Single oligonucleotide molecules with desirable binding properties are selected from diverse sequence libraries and identified by amplification and sequencing. Alternatively, selected oligonucleotide molecules are identified by sequencing without amplification. Nonnucleotide molecules with desirable properties are identified by single-molecule selection from libraries of conjugated molecules or nucleotide-encoded nonnucleotide molecules. Alternatively, target-specific nonnucleotide molecules are prepared by imprinting selected oligonucleotide molecules into nonnucleotide molecular media. Complexes and imprints of molecules identified by single-molecule selection are shown to have broad utility as drugs, prodrugs, drug delivery systems, willfully reversible cosmetics, diagnostic reagents, sensors, transducers, actuators, adhesives, adherents and novel multimolecular devices.

Systems, methods and processes teach by specific examples how the cost of sequestering carbon dioxide (CO2) can be totally offset and turned into profits during coal powered electricity generation from revenue and co-benefits. The process is provided whereby fly ash-carbon mixtures, or de-volatilized coal char, or anthracite coal culm is co-fired in an air-cooled, slagging combustor with limestone or similar slag fluxing materials converts the ash into cementitious slag with properties similar to ground granulated blast furnace slag.

A synthetic underwater visualization system (SUVS) comprising a real-time graphics software engine, a sophisticated underwater environmental sensor, a fixed-base database, and a retrieval system designed to accept and assimilate into a common database bathymetric and environmental information acquired from around the world by components of other deployed SUVS sensing systems. SUVS is capable of sensing, modeling, and realistically displaying underwater environments in real-time, and will foster widespread utilization in the areas of homeland security, commercial and recreational maritime navigation, bathymetric data collection, and environmental analysis. The technology will also be readily adaptable and highly desirable in non-marine applications.

The method disclosed by the invention has the advantages of simplicity and easiness in operation, controllable structure and morphology, controllable crystal form and electrochemical properties of metal oxides, and the like; the preparation method is environment-friendly, and nuisanceless, has no by-product, can be used for reducing the economic costs of traditional preparation methods, and can be popularized; and the transition metal oxide / carbon-based laminated composite material not only can be used as a key electrode material of a new energy storage device, but also can be used as a denitration catalyst, so that the material can be applied to the fields of environmental remediation, and the like.

A technique for controlling an irrigation system is disclosed. The technique comprises receiving landscape information, receiving environmental information, deriving an irrigation schedule based on the landscape information and the environmental information, and sending the irrigation schedule to an irrigation control unit.

This invention provides an environment controlling system and method thereof. The present system integrates and analyzes an individual's physiological and health information as well as environment information on a real-time basis to control environmental conditions and determine a living space beneficial to personal health. A healthy living space suitable for home care and disease management can be established by controlling environmental factors such as temperature, humidity, light, sound, etc.

Effective in-situ injection technology for the remediation of dense nonaqueous phase liquids (DNAPLs) such as trichloroethylene (TCE) benefits from the use of decontamination agents that effectively migrate through the soil media, and react efficiently with both dissolved TCE and bulk TCE. A novel decontamination system contains highly uniform carbon microspheres preferably in the optimal size range for transport through the soil. The microspheres are preferably enveloped in a polyelectrolyte (such as carboxymethyl cellulose, CMC) to which preferably a bimetallic nanoparticle system of zerovalent iron and Pd is attached. The carbon serves as a strong adsorbent to TCE, while the bimetallic nanoparticles system provides the reactivity. The polyelectrolyte serves to stabilize the carbon microspheres in aqueous solution. The overall system resembles a colloidal micelle with a hydrophilic shell (the polyelectrolyte coating) and a hard hydrophobic core (carbon). In contact with bulk TCE, there is a sharp partitioning of the system to the TCE side of the interface due to the hydrophobicity of the core. These multifunctional systems appear to satisfy criteria related to remediation and are relatively inexpensive and made with potentially environmentally benign materials. An aerosol process is preferably used to produce zerovalent iron particles supported on carbon. A method of lubricating includes creating carbon microspheres produced from a monosaccharide or polysaccharide, the carbon microspheres having a diameter of 50 nm to 6 microns, coating the microspheres with a surface coating and using the carbon microspheres as a lubricant.
