Modulation of Phenol Oxidation in Cofacial Dyads.
The presentation of two phenols on a xanthene backbone is akin to the tyrosine dyad (Y730 and Y731) of ribonucleotide reductase. X-ray crystallography reveals that the two phenol moieties are cofacially disposed at 4.35 Å. Cyclic voltammetry reveals that phenol oxidation is modulated within the dyad, which exhibits a splitting of one-electron waves with the second oxidation of the phenol dyad o...
متن کاملElectrochemical oxidation of benzene to phenol.
Gas-phase electrochemistry: The direct hydroxylation of benzene to phenol was investigated using an electrochemical cell. The production of phenol over a VO(x) anode was found to be significant at 50 °C. The resultant current efficiency for phenol production and selectivity toward phenol reached 76.5 and 94.7 %, respectively.
متن کاملA numerical study of supercritical water oxidation of phenol
Supercritical water oxidation has attracted attention of many researchers ever since the ideahas emerged about three decades ago as a promising technique in the waste managementindustry. Providing more details about the behavior of a supercritical water oxidation systemunder various operating conditions and extending available data can greatly assist more accurateand reliable design of such sys...
متن کاملOxidation causes melanin fluorescence.
PURPOSE The goal of this study is the characterization of the strong yellow fluorescence of oxidized melanin in the retinal pigment epithelium (RPE) and the choroid. METHODS Naturally occurring melanin in the human retina and choroid was oxidized by exposing fixed and plastic-embedded sections of a human eye to light and hydrogen peroxide. Synthetic melanin was also oxidized in vitro by expos...
متن کاملHypothalamic Amenorrhea: Causes, Complications, & Controversies
Hypothalamic amenorrhea (HA) is considered a reversible condition characterized by the absence of menses for 3 months or more, due to suppressed secretions of gonadotropin releasing hormone affecting the entire hypothalamic-pituitary-ovarian axis. HA can be triggered by excessive stress, weight loss or excessive exercise, however, the etiology is still largely unknown. Serious, long-term compli...
