Many propellant delivery systems use helium gas for storage, pumping, and pressurizing liquid propellants for in-space applications. To properly understand propellant tank functionality, reliable data on the solubilities of pressurant gases in these

This investigation studied the inclusion of various additives to paraffin wax for use in a hybrid rocket motor. Some of the paraffin-based fuels were doped with various percentages of LiAlH4 (up to 10%). Addition of LiAlH4 at 10% was found to increas

We have studied the oxidation of self-assembled monolayers (SAMs) of alkanes and alkenes with a thermal beam of OH radicals. The target films were produced by bonding alkane thiols and alkene thiols to a gold surface and the SAMs are mounted in a vac

We present experimental observations for the rotational state selection of formaldehyde. Data were acquired by using an electrostatic hexapole to focus a supersonic beam of formaldehyde seeded in argon into the ionizer of a quadrupole mass spectromet

A molecular beam source of pure hydroxyl radicals has been developed and used to explore the water reaction catalyzed over Pt(111). An electrostatic hexapole selectively focused OD radicals from a supersonic corona discharge source onto a Pt target a

Temperature-programmed desorption (TPD) measurements were made to probe the interactions of hydroxyl radicals (OD) with Pt(111). A pure, intense molecular beam of OD was prepared by filtering the effluent from a supersonic corona discharge D2O/He sou

Molecular beams of the b-type asymmetric top molecule methylenefluoride (CH2F2) were focused and rotationally state-selected with an electrostatic hexapole. The focusing behavior is mediated by the dependence of rotational energy on electric field st
