Electropolishing for Hydraulics and Pneumatics

Manufacturing components for the hydraulic and pneumatic industries often involve creating the ideal surface finish: neither too rough nor too smooth. When it comes to surface finish, electropolishing can help manufacturers walk that fine line and achieve the ultimate in function.

All-Organic Electroactive Device Fabricated with Single- Wall Carbon Nanotube Film Electrode

These devices have applications as electromechanical sensors, sonar, medical and optical devices, artificial muscles, and noise control. Langley Research Center, Hampton, Virginia A novel, all-organic electroactive device system has been fabricated with a single-wall carbon nanotube (SWCNT) film used as an alternative electrode. This system was fabricated with LaRC-Electro Active Polymer (LaRC-EAP) active layer and the SWCNT films by pressing at 600, 3,000, and 6,000 psi (≈4.1, 20.7, and 41.4 MPa, respectively). Silicone elastomer plates (3-mm thick) were used on the press plate surfaces for better contact adhesion between the SWCNT film and the actuating layer. This polymeric electroactive device layered with the SWCNT-FE (SWCNT-Film Electrode) can serve as an actuator. The density (or modulus) of the SWCNT-FE can be controlled by adjusting the fabrication pressure. It is anticipated that less dense SWCNT-FE can provide less constrain displacement of the polymeric actuating layer by matching the modulus.

Purifying Hydrogen for a Life Support Process

An advanced hydrogen purification technology is proposed to purify hydrogen of acetylene, carbon monoxide, and other gases to enable utilization of the hydrogen for oxygen recovery. Marshall Space Flight Center, Alabama NASA’s endeavor to further enable long-duration manned space exploration requires further closure of the oxygen loop of the life support system that is currently realized aboard the International Space Station. Currently, oxygen is recovered from crew-generated carbon dioxide via the use of a Sabatier carbon dioxide reduction system coupled with water electrolysis. Water is electrolyzed to form oxygen for crew consumption, as well as hydrogen. The hydrogen is reacted with carbon dioxide, forming water and waste methane gas. Since hydrogen is lost from the desired closed-loop system in the form of methane, there is insufficient hydrogen available to fully react all of the carbon dioxide, resulting in a net loss of oxygen from the loop. In order to further close the oxygen loop, NASA has been developing an advanced plasma pyrolysis technology that further reduces the waste methane to higher hydrocarbons in order to better utilize the hydrogen for oxygen recovery.

Low-Pressure Casting of Bulk Metallic Glasses for Gears and Other Applications

Applications include the automotive, aeronautics, aerospace, robotics, commercial, and military/defense industries. NASA’s Jet Propulsion Laboratory, Pasadena, California With the correct selection of composition, some bulk metallic glasses (BMGs) have been demonstrated that have excellent combinations of hardness, fracture toughness, and wear resistance so that their use in gears and gearboxes is a potentially commercially viable application. For BMGs to be used as a low-cost alternative to steel gears, rapid fabrication strategies are needed to cast the BMGs into net-shaped gears that require little or no post-casting machining prior to use. Die casting, suction casting, and other cold-mold casting techniques have been widely demonstrated for BMGs in the past, but the unique nature of gears precludes traditional techniques from being used in an optimal way.
