Abstract: A system and method for splitting water to produce hydrogen and oxygen employing focused polarized sunlight energy is disclosed. Hydrogen and oxygen may then be stored for later use as fuels. The system and method use inorganic capping agents that cap the surface of semiconductor nanocrystals to form photocatalytic capped colloidal nanocrystals, which may be deposited and oriented on a substrate to form an oriented photoactive material. The oriented photoactive material may be employed in the system to harvest sunlight and produce energy necessary for water splitting. The system may also include a light polarization system and elements necessary to collect, transfer, and store hydrogen and oxygen, for subsequent transformation into electrical energy.

Abstract: The present disclosure relates to biological material identification systems and methods. DNA oligomers may be used to encode for specific characteristics of biological materials. Encoding may be done by depositing suitable amounts of DNA oligomers onto a portion of a biological material. To identify the biological materials, the encoded portions of the biological materials may be extracted and immersed in buffer solutions. Then, lateral flow tests may be used to decode the DNA for interpretation, creating a readable barcode that may be compared with a database to determine if the biological material may be approved.

Abstract: A method for encoding and identifying biological materials is disclosed. The method may include encoding and identifying plants from which controlled substances may be derived and other materials for which movement and distribution may need to be tracked. The biological material may be first encoded using DNA oligomers. A spray method or the use of an encoded substrate, both using these DNA oligomers for encoding the biological material, may be employed. The biological material, or a part of the biological material, may be first encoded by atomizing a solution containing DNA oligomers onto it and then dried by an appropriate method. Thereafter, the part of the encoded biological material, or the nitrocellulose substrate, may be dissolved with a buffer solution for extracting the DNA oligomers. Then, the dissolved solution may be used for generating a barcode by a suitable detection scheme.

Abstract: The present disclosure provides a system capable of dispensing DNA encoding solutions at controllable flow rates and in uniform patterns, allowing sufficient DNA to be deposited onto a substrate for subsequent detection and identification of the substrate. The disclosed dispensing system may also include a feedback mechanism capable of validating that sufficient DNA has been applied to a substrate so that a barcode may be generated, detected, and identified at a later time.

Abstract: A system for splitting water and producing hydrogen for later use as an energy source may include the use of a photoactive material including PCCN and plasmonic nanoparticles. A method for producing the PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. The PCCN may be deposited between the plasmonic nanoparticles and may act as photocatalysts for redox reactions. The photoactive material may be used in presence of water and sunlight to split water into hydrogen and oxygen. Production of charge carriers may be triggered by photo-excitation and enhanced by the rapid electron resonance from localized surface plasmon resonance of plasmonic nanoparticles. By combining different semiconductor materials for PCCN and plasmonic nanoparticles and by changing their shapes and sizes, band gaps may be tuned to expand the range of wavelengths of sunlight usable by the photoactive material.

Abstract: A system employing sunlight energy for reducing CO2 into methane and water is disclosed. The system may include the use of a photoactive material including plasmonic nanoparticles and photocatalytic capped colloidal nanocrystals (PCCN). A method for producing the PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. Additionally, the PCCN may be deposited between the plasmonic nanoparticles, and may act as photocatalysts for redox reactions. The CO2 reduction system may use inorganic capping agents that cap the surface of semiconductor nanocrystals to form PCCN, which may be deposited on a substrate and treated to form a photoactive material. The photoactive material may be employed in the system to harvest sunlight and produce energy necessary for carbon dioxide reduction. The system may also include elements necessary to collect and transfer methane, for subsequent transformation into electrical energy.
