Characterization and Reactivity of Molecular Oxygen Species on Oxide Surfaces
M. Che,A.J. Tench +1 more
TL;DR: This chapter discusses the characterization and reactivity of mononuclear oxygen species on oxide surfaces and there is evidence from the examples for some of the species that are stable at much higher temperatures and may play an important role in catalytic reactions.

Charge Generation and Propagation in Igneous Rocks
TL;DR: In this article, it was shown that when dry gabbro and diorite cores are impacted at relatively low velocities, approximately 100 m/s, highly mobile charge carriers are generated in a small volume near the impact point.
Journal ArticleDOI
Electric currents streaming out of stressed igneous rocks - A step towards understanding pre-earthquake low frequency EM emissions
TL;DR: In this paper, it was shown that, when applied stresses to one end of a block of igneous rocks, two currents flow out of the stressed rock volume, i.e., defect electrons on the oxygen anion sublattice, and it flows out through at least 1 m of unstressed rock to meet the electrons that arrive through the outer electric circuit.

Time-resolved study of charge generation and propagation in igneous rocks
TL;DR: In this paper, the authors used low-to medium-velocity impacts to measure electrical signals with microsecond time resolution, and observed that when gabbro and diorite cores are impacted at relatively low velocities, ≈ 100 m/s, highly mobile charge carriers are generated in a small volume near the impact point.

Critical performance evaluation of catalysts and mechanistic implications for oxidative coupling of methane
TL;DR: In this paper, global performance data of catalysts used for oxidative coupling of methane are evaluated with the object of identifying good catalysts and correlating the observed activity trends with the catalyst compositions.

Electron spin resonance studies of radiation effects in inorganic solids
TL;DR: In this article, it was shown that the hole centres may be induced by grinding and x irradiation of magnesium oxide or other alkaline earth oxides, sulfides or selenides which have the MgO structure.

A hydrogen-containing trapped hole center in magnesium oxide☆
TL;DR: In this article, the 3296 cm −1 band is attributed to an OH− ion with hydrogen adjacent to the vacancy. But the authors refer to the new center as the V OH− center.

EPR Study of 17O− on Magnesium Oxide
Ning‐Bew Wong,Jack H. Lunsford +1 more
TL;DR: In this article, the EPR spectrum of 17O− on MgO has been obtained by the reaction of N2O containing 71.9% oxygen−17 isotope with trapped electrons on the surface.
