Abstract

Methods and apparatus for growing photosynthetic organisms lacking Photosystem II (PSII) function using externally supplied electrons shuttled into the organism using redox mediators to improve photosynthetic output and to produce and recover chemicals of interest. By removing PSII, all PAR photons are funneled toward Photosystem I, thereby significantly increasing the theoretical photon utilization efficiency for CO2 fixation, energy storage and the capacity to synthesize valuable chemicals. Additional genetic modification can be performed to insert or enhance specific metabolic pathways to generate products of commercial interest.

Polymer-hybrid electro-optic devices and method of fabricating polymer-hybrid electro-optic devices

Patent Ocola, Leonidas E.; Gosztola, David J.; Yanguas-Gil, Angel

A polymer-hybrid electro-optic device is fabricated by providing a semiconductor substrate, depositing a metal electrode layer on the semiconductor substrate, depositing a dielectric barrier core layer within a gap of the metal electrode layer, patterning a polymer layer to cover the dielectric barrier core layer and partially covering the metal electrode layer, infiltrating the polymer layer with an inorganic component to form a hybrid oxide-polymer layer, and removing excess inorganic component from the semiconductor substrate and metal electrode layer.

Artificial photosynthesis systems and methods for producing carbon-based chemical compounds

Patent Yang, Peidong; Chang, Michelle C. Y.; Chang, Christopher J.; ...

This disclosure provides systems, methods, and apparatus related to artificial photosynthesis. In one aspect a system includes a photoanode chamber including a photoanode assembly, a photocathode chamber including a photocathode assembly, an electrical connection electrically connecting the photoanode assembly and the photocathode assembly, a membrane separating the photoanode chamber and the photocathode chamber, and a microorganism disposed in the photocathode chamber. The photoanode assembly is operable to oxidize water to generate oxygen, protons, and electrons. The membrane is permeable to the protons and operable to allow the protons to travel to the photocathode chamber. The electrical connection provides electrons tomore » « less

Method for improving product yields in an anionic metalloporphyrin-based artificial photosynthesis system

Patent Shelnutt, John A [Albuquerque, NM]

A method for improving product yields in an anionic metalloporphyrin-based artificial photosynthesis system for hydrogen generation which comprises forming an aqueous solution comprising an electron donor, methylviologen, and certain metalloporphyrins and metallochlorins, and irradiating said aqueous solution with light in the presence of a catalyst. In the photosynthesis process, solar energy is collected and stored in the form of a gas hydrogen. Ligands attached above and below the metalloporphyrin and metallochlorin plane are capable of sterically blocking photochemically inactive electrostatically bound .pi.--.pi. complexes which can develop.
