O-phthalaldehyde (OPA) is a high-level disinfectant commonly used, for example, for sterilization of heat-sensitive medical instruments; it demonstrates effective microbicidal activity against a wide range of microorganisms (including mycobacteria, gramnegative bacteria, and spores). On the International Space...

Technology has been developed that provides a way to compute the remaining useful life (RUL) of a component or system. The estimation of the RUL of a degraded or faulty component is at the center of condition-based maintenance, and prognostics and health management. It gives operators a...

Internal electrostatic discharge (IESD) can cause spacecraft failure and anomalies related to the space environment, but it is very hard to predict when IESD might happen. Therefore, assessment of the IESD at a given space environment and a given dielectric geometry is important for spacecraft reliability.

ISAAC (Instrument Shared Artifact for Computing) offers adaptability, computation power, I/O bandwidth, digital interface standards, and data processing capability in a single, common, low-mass/power, and small-form-factor platform with significantly reduced, nonrecurring cost and risk...

In recent years, electrochemical capacitors, or supercapacitors, have gained the most intense interest as an alternative to traditional energy storage devices such as batteries. The demands of the potential supercapacitor applications range from plug-in hybrid electric vehicles (PHEVs) to...
