Graphene as Filler for Thermoplastic Nanocomposites

To save costs and reduce weight, a company is exploring graphene as a filler for thermoplastic resins. Work to date has shown that graphene dispersion is generally poor in thermoplastics, leading to less than optimal reinforcement properties and darker color. The manufacturer is specifically interested in the reinforcement properties of graphene in polyethylene and polypropylene. Potential solution proposals must include the source of the material, the matrix they are dispersing into, the level of transparency and color, and some measure of mechanical reinforcement.

Gauge Calibrates Three-Dimensional Coordinate Measuring Machine (CMM)

A gauge, which is used in examining the accuracy of a coordinate measuring machine (CMM), enables total calibration of errors and numbers of revisions of the measured values. The accurate calibration is possible for a CMM of any size. Various machines can also be calibrated by combining the gauge.

Inspection Technology Identifies Surface Defects

An automated surface inspection technology identifies potential defects on a painted surface so that they can be remedied. The system provides a database so that the size, location, quality, and other aspects of production line defects can be tracked over time.

Razor “Saws” Hair for Easier Shaving

With traditional razors, the cutting edge of a blade moves in the direction of the cut. A new shaving device, however, includes one or more blades that perform a vibrating motion perpendicular to the direction of the cut, and parallel to the blade’s edge; the hairs are cut by sawing, rather than cutting.

Medical Valves Withstand Magnetic Fields

Parker Hannifin has created design concepts for valves that can be used in MRI-compatible ventilators. The valves, built to work with a variety of medical fluids and gases, are unaffected by strong magnetic fields and, in turn, do not create any magnetic fields of their own. In addition, the valves can be designed to handle a range of operating characteristics while minimizing total footprint.

High-Temperature Seals for Non-Nuclear Test Facility

The United States National Research Council (NRC) has identified Nuclear Thermal Propulsion (NTP) as a high-priority NASA Space Technology Roadmap Area. NTP could be an enabling technology to reduce transit time and mission risk to Near-Earth Objects, Mars, and other deep space destinations. Nuclear power and propulsion technologies are key enabling technologies for future NASA exploration missions. The goal for Stennis Space Center is to investigate the technologies that would be required in the potential development of a Nuclear Propulsion and Power Nonnuclear (NP2N) test facility to provide component- and system-level ground testing of the NTP systems during the development and certification phases of their lifecycle.

Sterilizable Applicator for Pre-Mixed Liquid Formulation

An organization needs an inexpensive device to deliver a pre-measured amount of liquid evenly to a surface. The applicator is intended for a single use, must be able to be sterilized after final assembly, and needs to hold enough liquid or gel to cover about 1 to 3 square feet of surface completely. The user’s hands cannot touch either the liquid or the surface to which the liquid is being applied. The design should also be scalable so that units delivering as little as 3 mL can be manufactured.
