Abstract: The invention provides for the integration of a CO-consuming process, such as a gas fermentation process, with a CO2 electrolysis process. The invention is capable of utilizing a CO2-comprising gaseous substrate generated by an industrial process and provides for one or more removal modules to remove at least one constituent from a CO2-comprising gaseous substrate prior to passage of the gaseous substrate to a CO2 electrolysis module. The invention may further comprise one or more pressure modules, one or more CO2 concentration modules, one or more O2 separation modules, and/or an H2 electrolysis module. Carbon conversion efficiency is increased by recycling CO2 produced by a CO-consuming process to the CO2 electrolysis process.

Abstract: An apparatus comprises a slider having an air bearing surface, a first waveguide for directing electromagnetic radiation to a focal point adjacent to the air bearing surface, a storage medium position adjacent to the air bearing surface, a detector for detecting electromagnetic radiation reflected from the storage medium, and a structure positioned adjacent to the focal point for collecting the reflected electromagnetic radiation and for transmitted the reflected electromagnetic radiation toward the detector.

Abstract: A data writing system includes an array of cells for storing data and a write transducer that moves over a selected cell in the array of cells. The write transducer includes a writer producing a write magnetic field that intersects the selected cell. The write transducer also includes a plasmon resonator that is adjacent the writer. The plasmon resonator is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot intersecting with the selected cell. The plasmon radiation heats the selected cell above a write temperature.
