Electrospray wings for molecular elephants by John B Fenn( Visual )

3 editions published between 2003 and 2004 in English and held by 4 WorldCat member libraries worldwide

In a very technical lecture, Dr. Fenn discusses the history and applications of electrospray method for mass spectrometry to physics, chemistry, and biology. Dr. Fenn won the Nobel Prize in Chemistry (2002) for his work. He traces the history of the develop of mass spectrometry from gravimetric analysis to the work of Otto Stern's work on molecular beams. Dr. Stern won a Nobel Prize for Physics (1943). Dr. Fenn also describes the work of Arthur Krantrowitz and Jerry Grey on high intensity molecular beams. The original application was for supersonic jets. In addition, Dr. Fenn illustrates the work of John Zeleny of Yale identifying the electrospray. He describes the work of Malcolm Dole on determining the molecular weight of polymers. The goal of the experiments was to develop a method to create a single ion from a large molecule. Using information from these sources, Fenn and his post-doctoral student Masamachi Yamashita developed the first electrospray mass spectrometer
Thermal recovery factors in supersonic flows of gas mixtures by George Maise( Book )

3 editions published in 1969 in English and held by 4 WorldCat member libraries worldwide

Thermal recovery factors were measured at the stagnation point of a hemispheric probe in low density supersonic jets of helium-argon and hydrogen-nitrogen mixtures. A 'guard' heater in the probe made it possible to eliminate conduction losses. Radiation corrections were small. The final values correspond to adiabatic conditions. With jets of mixed gases the experimental recovery factors were as high as 1.6, substantially above the free molecule limit for pure gases. It is suggested that these anomalously high values are due to the species separation which occurs during the stagnation process and which results in concentrations of heavy species in the stagnation zone higher than in the free stream. The results are correlated in terms of the degree of rarefaction and the composition of the source gas. (Author)

Microscale electrospinning of polymer nanowires for sensing applications by Royal F Kessick( Book )

3 editions published in 2005 in English and held by 3 WorldCat member libraries worldwide

All project tasks have been completed. Prototype chemical and infrared sensors have been fabricated and tested and the performance parameters (presented below) are extremely promising. In addition a new fiber processing technology based on supercritical fluids has been developed and demonstrated. Finally, new polymeric helical structures have been developed and tested and represent a new technology for microscale sensing and actuation. At this time three journal articles (two in Applied Physics Letters and one in the Journal of Supercritical Fluids) have been published based on this research program and a fourth paper has been submitted to Sensors and Actuators. The research results have been presented at four international conferences including the AFOSR Molecular Dynamics and Theoretical Chemistry Conference and the SPIE Defense and Security Symposium. The following sections provide a detailed summary of the program accomplishments and new findings
Vacuum sublimation of ammonium perchlorate by Steve Tang( Book )

2 editions published in 1972 in English and held by 2 WorldCat member libraries worldwide

Time-of-flight measurements have been made on the flux of molecules from the surface of ammonium salts vaporizing into vacuum. As expected with ammonium halides and ammonium bi-sulfate the TOF distributions correspond to equimolar fluxes of ammonia and the corresponding acid. In the case of ammonium perchlorate the vapor subliming from a single crystal comprised ammonia and perchloric acid. When the source was compressed powder, the vapor was a mixture of lower molecular weight species. This result seems best explained in terms of subsurface decomposition. (Author)
Velocity Distributions of Several Gases Scattered from High Temperature Surfaces by A Cassuto( Book )

2 editions published in 1971 in English and held by 2 WorldCat member libraries worldwide

Polycrystalline surfaces of molybdenum, tungsten and rhenium at temperatures up to 2600K were exposed to free molecule flows of hydrogen, helium, nitrogen, oxygen and argon at Mach numbers up to 4 from a room temperature source. Time-of-flight measurements were made for molecules reflected in the surface normal direction. Apparent translational accommodation coefficients ranged from .01 for hydrogen on a hot surface to nearly unity for all gases on surfaces at room temperature. (Author)
Clustering of water on hydrated protons in a supersonic free jet expansion by J. Q Searcy( Book )

2 editions published in 1974 in English and held by 2 WorldCat member libraries worldwide

The paper presents results concerning size distribution and growth in the gas phase of ions in the series H+(H2O)n. The measurements span a range of cluster sizes up to n = 28, a domain not previously investigated quantitatively. The molecular beam sampling technique developed for this study promises to be a powerful tool in the study of ion nucleation phenomenon. Noteworthy observations include the unusual stability of the cluster with n = 21 and the absence of trapped molecules of carrier gas within a cluster. (Author)

A description of research on producing high energy molecular beams is given. Results of previously published work are summarized for the development of techniques for generating neutral beams in the 1 to 10 eV range using gas dynamic acceleration of heavy species by light carrier gases in nozzle flows from which molecular beams are extracted. Measurements of heavy species velocities, velocity distributions and intensities in the molecular beams formed are discussed in relation to theoretical predictions. Studies of the gas dynamics of free jets of pure gases and mixtures used as molecular beam sources are reported. A brief assessment of applications to research on atomic and molecular collision processes is included. (Author)
Strand size and low pressure deflagration limit in a composite propellant by Roy E Cookson( Book )

2 editions published between 1968 and 1969 in English and held by 2 WorldCat member libraries worldwide

The low pressure deflagration limit was determined for a composite ammonium chlorate propellant over a range of pressures from 35 torr to 235 torr. The independent variable was strand size in terms of cross-section dimensions. A linear relation was found between the 'hydraulic radius' of the strand and the low pressure limit. It was thus possible to extrapolate and determine the low pressure limit for a strand of infinite extent. At this limit it would seem that heat losses could only be by radiation from the surface
Background and sampling effects in free jet studies by molecular beam measurements by John B Fenn( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

The effects of finite background pressures on free supersonic jets from sonic nozzles were investigated. It was found that at sufficiently low jet densities, which were characterized in terms of nozzle Knudsen number, axial distance and background pressure level, the background gas freely invades the jet flow field. This invasion results in substantial scattering of the jet molecules with the consequence that molecular beams extracted from such jets suffer a marked attenuation of their intensity. Some possible implications with respect to previously observed species separation are discussed. (Author)
Intermolecular Energy Exchange by Infrared Radiometry( Book )

2 editions published between 1978 and 1980 in English and held by 2 WorldCat member libraries worldwide

Excitation by translational energy of the asymmetric stretch vibrational mode of ground state carbon dioxide molecules in collision with nitrogen, oxygen and argon molecules has been studied, by intersecting two slightly collimated molecular beams in the field of view of an InSb photovoltaic detector which monitored resulting radiation in the 4.3 micrometer band. The excitation cross sections for all three combinations of partners were of similar magnitude and showed a strong dependence upon collision velocity. For nitrogen the measured cross sections ranged from about 0.0008 square Angstroms at 2 km/s to about 0.5 square Angstroms at 5 km/s. A similar but separate experiment determined an upper limit of 0.1 square Angstroms for the collisional excitation of hydrogen fluoride by krypton at energies up to 1.7 times the threshold requirement. Bulk relaxation rates for molecules in free jet expansion were also investigated. Results obtained from experimental data with the frequently used Sudden Freeze Model have been compared with those obtained by Numerical Integration. Success has been achieved in obtaining Method-of-Characteristics solutions for the free jet expansion with a varying specific heat ratio. This development provides the best description yet of relaxation in free jet expansion for any internal mode which can be characterized by a Boltzmann distribution of energy. (Author)
Viscous effects on impact pressure measurements in low density flows at high mach numbers( Book )

1 edition published in 1968 in English and held by 2 WorldCat member libraries worldwide

Impact pressures were measured with hemispherical probes in free jets of argon, nitrogen and argon-helium mixtures. Free stream Mach numbers ranged from 2.8 to 23; probe Reynolds numbers from 2 to 2000. (Author)
