The NiceC Programming Language

NiceC is an improved version of ANSI C. It attempts to clean up C as much as possible using syntax translation. A type checker for NiceC is under development. The NiceC programming language is translated to, and fully compatible with, ordinary C. Thus it can be used as a drop-in replacement for C. The main benefits...

One-Step 3D Printing of Catalysts

While 3D printing has found applications in many areas, its use as a way to control chemical reactions, or catalysis, is relatively new. Current production of 3D catalysts typically involves various methods...

Bend- and Twist-Sensing Optical Fiber

A method was developed for concurrently measuring bending and twisting along an optical fiber using only the properties of light guided within the fiber. The method exploits polarization-dependent...

Development of Sodium Lidar for Spaceborne Missions

The metal layers at mesospheric altitudes are excellent tracers of neutral atmosphere dynamics, and have been used since the 1960s to study the chemistry and dynamics of the mesosphere. Ablation from meteors is believed to be the chief source of metals such as Na, Mg, K, Fe, and Ca in the...

APT Web Tool

Project planning data collected by the Analysis, Planning, and Tracking (APT) system during the planning cycle previously was available to users via an email request to a data administrator who would pull data from the database, format as requested, and respond via email. Access to the data was limited by the availability of the...

Aerosol-to-Liquid Particle Extraction System (ALPES)

Agents that could be used in chemical and biological warfare tend to disperse widely in the air when released. Quickly collecting a concentrated sample of these agents is critical to detecting them before they reach harmful dose levels in the air. Also, methods of detection such as by...

Conductive, High-Toughness Oxides Deposited by Plasma Spray-Physical Vapor Deposition (PS-PVD)

Oxide coatings deposited in Glenn Research Center's Plasma Spray-Physical Vapor Deposition (PS-PVD) facility can be processed to be mechanically tough (erosion-resistant) and electrically conductive at room temperature. The electrically conductive...

Echo Analysis Environment for Analyzing Large, Complex Datasets

Analyzing data piecemeal is usually uninformative. Analysts need tools to evaluate multiple pieces of data simultaneously that are related by a common thread. Identifying that...

Sensor Detects Nuclear Weapon Solvent

A new sensor picks up signatures of tributyl phosphate, a solvent used to enrich uranium, including for use in a nuclear weapon. Enzymes can detect tributyl phosphate signatures, but the lifespan of the enzymes is too short to make them practical for sensors.

Depth Sensors for Time-of-Flight Imaging

Time of flight is an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. In time-of-flight imaging, a short burst of light is fired...

Superalloy Surface Treatment for Improved Performance of Power Turbines

To produce power more efficiently and cleanly, the next generation of power turbines will have to operate at extreme temperatures and pressures. Currently, single-crystal, nickel-based superalloys are used in such extreme environments. MCrAlY coatings (where M = Co, Ni, or...
