Oxidative stress and growth temperature in Bacillus subtilis.
(1987)Pretreatment of Bacillus subtilis with low concentrations of hydrogen peroxide protected the cells against the lethal effects of higher levels of oxidative stress. During the period of adaptation, eight proteins were ... -
Oxidative stress, mitochondrial dysfunction and calcium overload in human lamina cribrosa cells from glaucoma donors.
(2011)Oxidative stress is implicit in the pathological changes associated with glaucoma. The purpose of this study was to compare levels of oxidative stress in glial fibrillary acid-negative protein (GFAP) lamina cribrosa (LC) ... -
Oxide template for self-assembling arrays of metal nanoclusters
(2006)We demonstrate that ordered arrays of metal clusters of a few nanometers in size can be fabricated by self-assembly on a range of oxide nanotemplates. Two systems were chosen, FeO/Pt(111) and Fe3O4, having in common a ... -
Oxide-mediated recovery of field-effect mobility in plasma-treated MoS<inf>2</inf>
(2018)Precise tunability of electronic properties of two-dimensional (2D) nanomaterials is a key goal of current research in this field of materials science. Chemical modification of layered transition metal dichalcogenides leads ... -
Oxo-Free Hydrocarbon Oxidation by an Iron(III)-Isoporphyrin Complex
(2020)Metal-halides that perform proton coupled electron-transfer (PCET) oxidation are an important new class of high-valent oxidant. In investigating metal-dihalides, we reacted [FeIII(Cl)(T(OMe)PP)] (1, T(OMe)PP = meso-tetra ... -
Oxygen Electromigration and Energy Band Reconstruction Induced by Electrolyte Field Effect at Oxide Interfaces
(2018)Electrolyte gating is a powerful means for tuning the carrier density and exploring the resultant modulation of novel properties on solid surfaces. However, the mechanism, especially its effect on the oxygen migration and ... -
Oxygen evolution at oxidized iron electrodes: a tale of two slopes
(2012)The electro-catalytic activity with respect to water oxidation to form molecular oxygen of iron oxyhydroxide thin films on iron support surfaces in aqueous base is described. A mechanism involving iron surfaquo groups is ... -
