Conformation of NADH studied by fluorescence excitation transfer spectroscopy

Autor: Paul S. Conger, Robert V. Hull, Ray Hoobler

Publikováno v: Biophysical Chemistry. 90:9-16

Dihydronicotinamide adenine dinucleotide (NADH), is known to stack in two limiting conformations. Surprisingly, previous experimental work on NADH has not clearly defined whether this folding and unfolding process can be described as first order (inv

Direct measurements of rate coefficients for the reaction of ethynyl radical (C2H) with C2H2at 90 and 120 K using a pulsed Laval nozzle apparatus

Autor: Seonkyung Lee, David A. Samuels, Stephen R. Leone, Ray Hoobler

Publikováno v: Journal of Geophysical Research: Planets. 105:15085-15090

Rate coefficients for the reaction C2H + C2H2 → C4H2 + H are measured at 90 and 120 K by using a new pulsed Laval nozzle apparatus equipped with laser ionization, time-of-flight mass spectrometric detection. The C2H radicals are generated by 193 nm

A pulsed Laval nozzle apparatus with laser ionization mass spectroscopy for direct measurements of rate coefficients at low temperatures with condensable gases

Autor: Seonkyung Lee, Stephen R. Leone, Ray Hoobler

Publikováno v: Review of Scientific Instruments. 71:1816-1823

A pulsed Laval nozzle, low Mach number supersonic expansion kinetics apparatus has been constructed to study neutral–neutral kinetics by a rather general laser photolysis initiation and laser photoionization detection of the product species. This n

Rate coefficients for reactions of ethynyl radical (C2H) with HCN and CH3CN: Implications for the formation of complex nitriles on Titan

Autor: Ray Hoobler, Stephen R. Leone

Publikováno v: Journal of Geophysical Research: Planets. 102:28717-28723

Rate coefficients for the reactions of C2H + HCN yields products and C2H + CH3CN yields products have been measured over the temperature range 262-360 K. These experiments represent an ongoing effort to accurately measure reaction rate coefficients o

Low-Temperature Rate Coefficients for Reactions of Ethynyl Radical (C2H) with Propane, Isobutane, n-Butane, and Neopentane

Autor: Brian J. Opansky, Ray Hoobler, Stephen R. Leone

Publikováno v: The Journal of Physical Chemistry A. 101:1338-1342

Low-temperature rate coefficients for the reactions of C2H + RH → products (RH = C3H8, i-C4H10, n-C4H10, and neo-C5H12) have been measured over the temperature range 154−361 K. Measurements were ma...

Models for reticle performance and comparison of direct measurement

Autor: Terrence E. Zavecz, Ray Hoobler

Publikováno v: Optical Microlithography XVIII.

It’s commonly reported that a difference exists between directly measured reticle feature dimensions and those produced in the final lithographic image. Quantifying this mask error function (MEF) and the sources of the perturbation has been the top
