C07F 15/00
C07D 403/00

US Classification:

423226, 548101, 548255

Abstract:

Various methods and structures of complexes and molecules are described herein related to a zinc-centered catalyst for removing carbon dioxide from atmospheric or aqueous environments. According to one embodiment, a method for creating a tris(triazolyl)pentaerythritol molecule includes contacting a pentaerythritol molecule with a propargyl halide molecule to create a trialkyne molecule, and contacting the trialkyne molecule with an azide molecule to create the tris(triazolyl)pentaerythritol molecule. In another embodiment, a method for creating a tris(imidazolyl)pentaerythritol molecule includes alkylating an imidazole 2-carbaldehyde molecule to create a monoalkylated aldehyde molecule, reducing the monoalkylated aldehyde molecule to create an alcohol molecule, converting the alcohol molecule to create an alkyl halide molecule using thionyl halide, and reacting the alkyl halide molecule with a pentaerythritol molecule to create a tris(imidazolyl)pentaerythritol molecule. In another embodiment, zinc is bound to the tris(triazolyl)pentaerythritol molecule to create a zinc-centered tris(triazolyl)pentaerythritol catalyst for removing carbon dioxide from atmospheric or aqueous environments.

Appl. No.:

13/117079

Inventors:

Sarah Elyse Baker - PLEASANTON CA, US
Tiziana Bond - LIVERMORE CA, US
Allan Shih-Ping Chang - SAN RAMON CA, US

International Classification:

G01N 33/554
G06F 19/00
C12Q 1/70

US Classification:

702 19, 435 732, 435 5

Abstract:

Isolation of biological or chemical organisms can be accomplished using a surface enhanced Raman scattering (SERS) system. The SERS system can be a single or a stacked plurality of photonic crystal membranes with noble-metal lined through pores for flowing analyte potentially containing the biological or chemical organisms. The through pores can be adapted to trap individual biological or chemical organisms and emit SERS spectra, which can then be detected by a detector and further analyzed for viability of the biological or chemical organism.

B01J 23/00

US Classification:

210668, 2102421

Abstract:

A system is provided that substantially increases the efficiency of COcapture and removal by positioning a catalyst within an optimal distance from the air-liquid interface. The catalyst is positioned within the layer determined to be the highest concentration of carbon dioxide. A hydrophobic tether is attached to the catalyst and the hydrophobic tether modulates the position of the catalyst within the liquid layer containing the highest concentration of carbon dioxide.

International Classification:

H01M 10/6568
H01M 4/04
H01M 10/6561

Abstract:

Disclosed are electrochemical reactors with electrodes that have variable porosity across the electrode. The electrodes are designed and micro-architected to have variable porosity and 3D flow. In one aspect, an electrochemical cell apparatus is disclosed. The apparatus includes an electrochemical vessel and an electrochemical fluid contained in the electrochemical vessel. The apparatus further includes a porous electrode submerged in the electrochemical fluid in the electrochemical vessel, the porous electrode having different porosities in different areas of the porous electrode. The different porosities inhibit electrochemical fluid flow and increase electrical conductivity in first areas of the porous electrode with decreased porosity compared to second areas, and enable increased electrochemical fluid flow and decrease electrical conductivity in the second areas of the porous electrode with increased porosity compared to the first areas.

Abstract:

Generation of energy and storage of energy for subsequent use is provided by electromethanogenesis of carbon dioxide into a fuel gas and the storage of the fuel gas for subsequent use. An electromethanogenic reactor includes an anode conductor and a cathode conductor wherein the cathode conductor includes submicron to micron scale pores. Electromethanogenesis microbes and/or enzymes are located in the micron scale pores of the cathode electrode conductor. Carbon dioxide is introduced into the electromethanogenic reactor and the electromethanogenesis microbes/enzymes and the carbon dioxide interact and produce a fuel gas. The fuel gas is stored for subsequent use, for example use in power generation.
