The Invention describes LED illuminated photocatalytic fluid purification systems, especially for use for ethylene mitigation and control in agricultural, horticultural and floricultural growth, storage and transport modules. Aspects of the invention include systems integration with grow lights, ethylene and plant stress sensors, and communication with external control and data sources.

Photocatalytic fluid purification systems

Monolithic composite photocatalysts for fluid purification are disclosed. The monolithic composite photocatalysts comprise a photoactive nanocrystal component and a non-photoactive porous support. Photocatalytic fluid purification systems that contact an impurity-containing fluid with the subject monolithic composite photocatalysts are also disclosed. The monolithic composite photocatalysts may be affixed to or embedded in scaffold structures to promote fluid flow through a fluid purification system and contact with the monolithic composite photocatalysts.

Monolithic composite photocatalysts

Polymer coatings and surfaces are disclosed with antimicrobial properties. The antimicrobial action is provided by high surface area materials contained within the coating or surface. The high surface area materials may contain photocatalysts that create reactive oxygen species upon exposure to visible light or transition metals that create reactive oxygen species upon exposure to hydrogen peroxide. The high surface area materials may also sorb disinfecting liquids and desorb them over time to provide disinfection.

Antimicrobial surface systems

Fluid purification systems employing a monolithic composite photocatalyst to remove volatile organic compounds (VOCs) and/or pathogenic organisms are disclosed. Pairing of systems tuned to abate each of these materials are discussed in different configurations such as series and parallel, as well as combining systems to target both materials simultaneously. System configurations that allow a portion of the fluid stream to be purified are also disclosed as are configurations that allow regeneration of the photocatalyst. These features may be augmented by sensors that allow closed loop control of bypass and regeneration cycles in the systems.

Combined VOC mitigating and antimicrobial systems

The Invention describes photocatalytic reactor systems that employ fluidization of the photocatalyst. These systems are useful for performing chemical transformations on a chemical containing fluid, including for VOCs. Aspects of the invention include non-imaging optics, abrasion resistant coatings and photoreactor designs.

Photocatalytic fluidized bed reactor systems

Monolithic composite photocatalysts for fluid purification, chemical transformations, and surface sterilization are disclosed. The monolithic composite photocatalysts comprise a photoactive nanocrystal component and a non-photoactive porous support. Photocatalytic fluid purification systems that contact an impurity-containing fluid with the subject monolithic composite photocatalysts are also disclosed.

The Invention describes integration of photocatalytic materials into composite surfaces in order to achieve antimicrobial properties. Aspects of the invention include types of photocatalytic materials and methods to achieve long lifetimes, high durability and mechanical robustness, for application to medical and sanitary uses, among others. In particular, the invention describes production of photocatalytic islands on a porous support substrate, and various methods to prevent full contact of a matrix material with the photocatalytic islands on the porous support substrate when forming the photocatalytic composite. Reducing the area of contact between the matrix material and the photocatalytic material improves the lifetime of the photocatalytic materials employed in the photocatalytic composite.

Photocatalytic surface systems

A carbon pyrolyzate material is disclosed, having utility as an adsorbent as well as for energy storage and other applications. The pyrolyzate material comprises microporous carbon derived from low cost naturally-occurring carbohydrate source material such as polysaccharides. In adsorbent applications, the carbon pyrolyzate may for example be produced in a particulate form or a monolithic form, having high density and high pore volume to maximize gas storage and delivery, with the pore size distribution of the carbon pyrolyzate adsorbent being tunable via activation conditions to optimize storage capacity and delivery for specific gases of interest.

Microporous carbon monoliths from natural carbohydrates

A particulate form carbon pyrolyzate adsorbent, having the following characteristics: (a) COcapacity greater than 105 cc/gram at one bar pressure and temperature of 273&#xb0; Kelvin; (b) COWorking Capacity greater than 7.0 weight percent; (c) COheats of adsorption and desorption each of which is in a range of from 10 to 50 kJ/mole; and (d) a CO/NHenry's Law Separation Factor greater than 5. The carbon pyrolyzate material can be formed from a polyvinylidene chloride-based polymer or copolymer, or other suitable resin material, to provide an adsorbent that is useful for carbon dioxide capture applications, e.g., in treatment of flue gases from coal-fired power generation plants.

A carbon pyrolyzate adsorbent is described that is selective for carbon dioxide in contact with gas mixtures including carbon dioxide and methane. The adsorbent has a carbon dioxide adsorbent capacity at 1 bar pressure of greater than 50 cmcarbon dioxide per gram of adsorbent at 273K, a methane adsorption capacity at 1 bar pressure of less than 35 cmmethane per gram of adsorbent at 21&#xb0; C., and a bulk density of greater than 0.55 gram per cubic centimeter of volume. Such adsorbent can be utilized, for example, for biogas upgrading, natural gas purification, coal bed methane purification, and refining operations.

A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions include novel corrosion inhibitors. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.
