Kinetic evaluation of the solvolysis of isobutyl chloro- and chlorothioformate esters
Beilstein Journal of Organic Chemistry, 2011 The specific rates of solvolysis of isobutyl chloroformate (1) are reported at 40.0 °C and those for isobutyl chlorothioformate (2) are reported at 25.0 °C, in a variety of pure and binary aqueous organic mixtures with wide ranging nucleophilicity and ...

Development of a multiwire position sensitive proportional counter [PDF]
Nuclear Technology and Radiation Protection, 2011 Preliminary measurements in a proportional counter with two independently counting wires have shown that counting rates up to 106 counts/s per wire can be reached without critical loss in the “true versus measured” linearity relation. In this paper, a

Atoms, 2023 Although the comparison of fully differential ionization data for particle and antiparticle impact provides the ultimate tests of theoretical models, only very low antiparticle beam intensities are available. Hence, few experiments of this type have been

Modulated voltage metastable ionization detector [PDF]
, 1985 The output current from a metastable ionization detector (MID) is applied to a modulation voltage circuit. An adjustment is made to balance out the background current, and an output current, above background, is applied to an input of a strip chart ...

Self-Sustained Ionization and Vanishing Dead Zones in Protoplanetary Disks
, 2005 We analyze the ionization state of the magnetohydrodynamically turbulent protoplanetary disks and propose a new mechanism of sustaining ionization. First, we show that in the quasi-steady state of turbulence driven by magnetorotational instability in a ...

Field dependence of impact ionization coefficients in In0.53Ga0.47As [PDF]
, 2003 Electron and hole ionization coefficients in In/sub 0.53/Ga/sub 0.47/As are deduced from mixed carrier avalanche photomultiplication measurements on a series of p-i-n diode layers, eliminating other effects that can lead to an increase in photocurrent ...

Current-voltage characteristic of parallel-plane ionization chamber with inhomogeneous ionization
, 2007 The balances of particles and charges in the volume of parallel-plane ionization chamber are considered. Differential equations describing the distribution of current densities in the chamber volume are obtained. As a result of the differential equations

Ionization state of inter-stellar medium in galaxies: evolution, SFR-M * -Z dependence, and ionizing photon escape [PDF]
, 2013 We present a systematic study for ionization state of inter-stellar medium in galaxies at z=0-3 with ~140,000 SDSS galaxies and 108 intermediate to high redshift galaxies from the literature, using an ionization-parameter sensitive line ratio of [OIII ...
