Geodesolver for the Geodesic Equation

NASA has a need to determine the distribution of dark matter around planets like Earth. Doing so necessitates the ability to repeatedly solve the geodesic equation in simulations of weakly interacting particles streaming through bodies described by a Schwarzschild metric. Geodesolver numerically solves the...

Passive In-Situ Gas and Chemical Sensor

In many chemical processes, it is often desirable to detect the presence, quantity, and/or qualities of certain chemicals of interest; for example, in many closed chemical processes (either batch or...

Despite years of effort to stabilize proteins outside of their native environments, scientists have made limited progress in combining proteins with synthetic components like fibers without...

Innovators at NASA's Glenn Research Center have adapted a process to apply thermal and environmental barrier coatings using a unique combination of a plasma spray (PS) process and...

A polymer was discovered that possesses many of the same characteristics as plastics, such as light weight, heat resistance, strength, and durability. But the new polymer, unlike...

Trilinear Line Scan Cameras

Teledyne e2v (Milpitas, CA) has announced its next generation of line scan cameras — the high-resolution ELiiXA+ trilinear color range. These new 8k pixel...

Over the past decade, researchers have been working to create nanoscale materials and devices using DNA as construction materials through a process called DNA origami. A single long “sca...
