Development of Oxygen Scavenger Additives for Future Jet Fuels. A Role for Electron-Transfer-Initiated Oxygenation (ETIO) of 1,2,5-Trimethylpyrrole?

March 1, 2000
Author(s)
B Beaver, V Sharief, Y Teng, R DeMunshi, J P. Guo, E Katondo, D Gallagher, David M. Bunk, J Grodkowski, Pedatsur Neta
Model autoxidative, radiolytic and product studies are presented which explore the potential of 1,2,5-trimethylpyrrole (TMP) as an oxygen scavenger additive for future jet fuels. The results are consistent with a mechanism for the initial stages of the

Reversible CO2 Hydrogenation, Neutron Crystallography, and Hydride Reactivity of a Triiridium Heptahydride Complex

April 1, 2025
Author(s)
Valeriy Cherepakhin, Van K. Do, Anthony J. Chavez, Jacob Kelber, Ryan Klein, Eric Novak, Yongqiang Cheng, Xiaoping Wang, Craig Brown, Travis J. Williams
The authors report the structure, reactivity, and catalytic utility of a triiridium complex, [Ir3H6(μ3-H)(PN)3]2+ (2-H, PN = (2-pyridyl)CH2PBut2). Despite its unusual stability to unsaturated organics, electrophiles, and even CF3SO3D, they find that

Chemisorbed Oxygen on Ni(110) Studied by Spin Polarized Inverse Photoemission

January 1, 1985
Author(s)
C Feigerle, A Seiler, J Pena, Robert Celotta, Daniel T. Pierce
Dissociative chemisorption of O2 on the surface on Ni(110) has been investigated by the techniques of AES, LEED, and spin polarized inverse photoemission spectroscopy (SPIPES). SPIPES provides a unique method for studying the empty electronic states of the

Differences in PDMS Modification Affect Laminin Deposition and Smooth Muscle Cell Response

August 16, 2009
Author(s)
Joy P. Dunkers, Hae-Jeong Lee, Marvi Matos, Lisa Pakstis, Juan M. Taboas, Steven D. Hudson, Marcus T. Cicerone
When culturing cells on flexible surfaces, it is important to consider extracellular matrix treatments that will remain on the surface under mechanical strain. Here we investigate differences in laminin surfaces that were deposited on oxidized PDMS (plasma
