Synthesis of heterocyclic aromatic compounds has been pursued for a long time by chemists in order to analyze their properties and potential applications in biomedical and materials sciences including electronic devices such as organic light emitting devices (OLEDs) and in hydrogen storage.

Scientists at NASA’s Goddard Space Flight Center in Greenbelt Maryland are in the early stages of designing a sample-collecting comet harpoon. NASA Goddard’s Donald Wegel, lead engineer on the project, will work with researchers to send a spacecraft to rendezvous...

Progress has been made into adapting and enhancing a commercially available infrared spectrometer for the development of a handheld device for in-field measurements of the chemical composition of various samples of materials. The intent is to duplicate...

A miniaturized instrument for performing chemical and isotopic analysis of rocks has been developed. The rock sample is ablated by a laser and the neutral species produced are analyzed using the JPL-invented miniature mass spectrometer. The...

A system allows crime scene and accident scene investigators the ability to acquire visual scene data using cameras for processing at a later time. This system uses a COTS digital camera, a photogrammetry calibration cube, and 3D photogrammetry processing software.

DLiSPS is a collection of software modules that processes lidar data and displays/archives the output products. It has the same features as the real-time version written in C++, except the hardware control capability, with many other functionalities for off-line lidar signal processing. DLiSPS is...

Powerful new parallel data mining algorithms can produce diagnostic and prognostic numerical models and analyses from observational data. These techniques yield higher-resolution measures than ever before of environmental parameters by fusing synoptic imagery and time-series measurements. These techniques...
