Influences of Reaction Parameters on the Product of a Geothermite Reaction: A Multi-Component Oxidation-Reduction Reaction Study
This study investigated an oxidation-reduction reaction involving a mixture of minerals, glass, and aluminum that exhibited thermite-type reaction behavior. Thermite reactions are a class of Self-propagating High-temperature Synthesis (SHS) reactions. Chemical reactions between raw minerals and a …

Reducing of iron corrosion in water pipelines by hydrogen addition
… of iron in the pipelines is the result of an oxidation reduction reaction. In that reaction hydrogen ion is reduced and the iron is oxidized. The hypothesis of this thesis is that the electrochemical potential of the hydrogen half-cell reaction can be reduce by dissolution of hydrogen gas in …

Cation radical induced oxidative chemistry of hydrazones and oximes
Electron transfer reactions of cation radicals have drawn much interest (1). Shine and Sugiyama were the first to observe that alkyl radicals were formed by an initial electron transfer step in reactions of thianthrene cation radical with organomercurials (2). The possibility that thianthrene …

Effect of citrate on the redox properties of cytochrome C and its kinetic and binding behaviour with cytochrome oxidase /
… (30 mM) decreases the rate of cytochrome ~ reduction by ascorbate. This effect is also seen at both high (600 mM) and low (19 mM) ionic strengths, and the Kapp for citrate increases with increasing ionic strength. Citrate binds d both ferri -and ferrocytochrome ~, but with a lower affinity …

Ferric/ferrous determinations in synthetic biotite
… Fe, Al, and Mg contents among biotites. A simple oxidation-reduction reaction is used to relate changes in the non-steric ferric iron to hydrogen fugacity and temperatures for the Fe-Mg-Al biotites. The equilibrium constant for the reaction can be expressed as: (1) log K= 3607.2/T - 4.47 where, …

Testing the ancient marine redox record from oxygenic photosynthesis to photic zone euxina
… of oxygenic photosynthesis relative to the Great Oxidation Event (GOE; ~2.4 Ga) is poorly constrained. After the deep ocean became oxygenated in the early Phanerozoic, hydrogen sulfide, which is toxic to most aerobes, may have transiently accumulated in the marine photic zone (i.e. photic zone …

Processes Affecting the Behavior of Redox-Sensitive Elements in Chesapeake Bay
… of an estuary, including (1) biogeochemical reactions in the water column, (2) advective transport, and (3) diffusion from underlying sediments.</p> <p>The purpose of the study was to establish whether estuarine redox reactions are controlled by a complex interaction of processes 1 to 3. …

STRUCTURE REFINEMENT OF CYTOCHROME C555 (CHLOROBIUM, THIOSULFATOPHILUM).
… for its evolutionary implications. Second, the oxidation-reduction potential of cytochrome c₅₅₅ is significantly different from the oxidation-reduction potential of other cytochromes whose structures have been determined. Comparisons with the other structures would provide information concerning …

Quantum chemical modeling of redox reactivity, degradation pathways and persistence for aqueous phase contaminants
… that are reported here for the first time. The oxidation of HMPA is estimated to require at least iron-reducing conditions at low to neutral pH, and nitrate-reducing conditions at high pH. Furthermore, the transformation of HMPA by permanganate, a common groundwater remediation agent, is …
