Contamination modeling provides important insights into the transport mechanisms among sources, sinks, and sensitive surfaces. It is an indispensable tool in the discipline of contamination control and is often used to predict the outcome of a contam

The notion of percent area coverage (PAC) has been used to characterize surface cleanliness levels in the spacecraft contamination control community. Due to the lack of detailed particle data, PAC has been conventionally calculated by multiplying the

Contamination control plays an important role in sustaining spacecraft performance. One spacecraft degradation mechanism involves long-term on-orbit molecular outgassing from spacecraft materials. The outgassed molecules may accumulate on thermal con

Perfluorinated compounds (PFCs), notably perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), have been reported in human blood. Furthermore, the occurrence of PFCs in the blood of newborn babies, coupled with the need to study the pote

Pressure dependence of the tunneling rate for the hydrogen transfer photoreaction in acridine: fluorene was investigated at 1.4 K. Above 10 kbar, the rate rises exponentially with increasing pressure. These data constitute a measurement of tunneling

A delocalized electron at a metal-dielectric interface interacts with the adlayer and spatially localizes or self-traps on the femtosecond time scale into what is termed a small polaron. The dynamics can be studied by two-photon photoemission. Theore

We demonstrate a numerical technique for registering multiple frames of point cloud data from an airborne 3D flash ladar system that we have designed, built, and flown. This technique stitches together ladar data even in the presence of inaccuracies
