Oxygen gas sensor fabrication and characteristics Fig. 1: Sensing platform for oxygen transport through pulmonary membranes. Full size image The mechanism of oxygen sensing is that in the FET sensor, the applied gate voltage induces a surface potential, thereby modulating channel conductance (Fig.2a)...
Oxygen has two allotropic forms, diatomic (O2) and triatomic (O3, ozone). The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for theparamagnetismof oxygen. The three atoms in theozonemoleculedo not lie along a straight lin...
For a given system of N indistinguishable gas molecules (such as pure O2) the total partition function of the system is given by \(Q = \frac{{q^N}}{{N!}}\), where q is the total partition function of individual molecule in transition state, expressed as the product of partition ...
All of these processes are a result of low energy ion-molecule collisions (0.1 - 49 eV[sub lab]). The normalized intensity of the fullerence products exhibit little dependence on size of fullerence clusters examined. However, the reactivities of the fullerenes are found to be highly dependent...

17. Dainton and Norrish found that the addition of inert gas increases the induction period and narrows the explosion region in agreement with the observation of Thompson and Hinshelwood that nitrogen depresses the U.C.C. Sign in to download full-size image FIG. 17. Induction periods and ...
molecule in the bulk ionomer (m2 s−1), KO2 is the Henry constant (mol m−3 Pa−1), δ is the ionomer thickness (m), and kion/Pt and kion/gas are the apparent rate constants of oxygen permeation through the ionomer/Pt and ionomer/gas interfaces (m s−1), ...
Full size image Since the dipolar interaction is inversely proportional to the cube of the distance between two17O atoms, the detected correlations in Fig.2ashould mainly originate from 2-bond17O-Al-17O correlation rather than 4-bond17O-Al-O-Al-17O correlation by considering the transfer eff...
