Abstract: An apparatus includes a shaft assembly and swashplates fixed on the shaft assembly facing opposite to each other. At least two double rod cylinders are configured to reciprocate parallel to the shaft assembly between the swashplates. The at least two double rod cylinders are configured to push against the swashplates in either direction. This is done in such a way that the at least two double rod cylinders generate rotational force in the same direction at the shaft assembly. The apparatus may be used as a fluid motor, a fluid compressor (also called a pump) or an internal combustion engine (either with or without a guide path provided by or formed in the swashplates).

Abstract: The present disclosure provides for systems and methods for producing carbon nanotubes. More particularly, the present disclosure provides for improved systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using a carbon source in the presence of a catalyst. In exemplary embodiments, the present disclosure provides for improved systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using carbon monoxide (CO) disproportionation in the presence of a catalyst composition on a catalyst support material. In one embodiment, the present disclosure provides for systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using carbon monoxide (CO) disproportionation with CO pressure from about 0.20 atm to about 1.0 atm in the presence of a cobalt/molybdenum catalyst composition on a magnesium oxide catalyst support.
