The effects of ultraviolet and x-ray irradiation are described, and the results are interpreted in terms of valence changes of impurities, principally iron. A method for the analysis of the photoconductivity data is given. This method corrects for the effects of strong nonionizing absorption, which may lead to spurious peaks in photoconductivity spectra. The sign of the optically excited charge carriers was deduced by a method which involves the formation of a space-charge field by the motion of carriers in an applied electric field, and the detection of the asymmetry in this space-charge field when carriers are subsequently allowed to move under the influence of the space-charge field only. A band centered at 5.05 ev has been detected in all specimens measured and this is believed to be due to the impurity Fe2+. Irradiation in this band provides free electrons some of which are believed to be trapped by other Fe2+ ions. Three absorption bands previously observed by other authors are believed to be associated with the impurity Fe3+.</p>]]></content:encoded> <category><![CDATA[Magnesium Oxide]]></category> <link>https://rawgoods.org/MagnesiumOxide/magnesium-oxide-crystals</link> <guid isPermaLink="true">https://rawgoods.org/MagnesiumOxide/magnesium-oxide-crystals</guid> <pubDate>Wed, 24 Apr 2024 11:10:00 +0000</pubDate> </item> <item> <title>Oxidizing Atmosphere</title> <description>A reducing atmosphere is an atmospheric condition in which oxidation is prevented by removal of oxygen and other oxidizing gases or vapours, and which may contain actively reducing gases such as hydrogen, carbon monoxide and ...</description> <content:encoded><![CDATA[<img src="/img/longquan_celadon.jpg" alt="Oxidizing atmosphere which" align="left" /><p>A reducing atmosphere is an atmospheric condition in which oxidation is prevented by removal of oxygen and other oxidizing gases or vapours, and which may contain actively reducing gases such as hydrogen, carbon monoxide and gases that would oxidize in the presence of oxygen, such as hydrogen sulfide. Materials processing [edit] In metal processing, a reducing atmosphere is used in annealing ovens for relaxation of metal stresses without corroding the metal. An inert gas, usually nitrogen, is used, or for more extreme conditions, hydrogen gas. A reducing atmosphere is also used in order to produce specific effects on ceramic wares being fired. A reduction atmosphere is produced in a fuel fired kiln by reducing the draft and depriving the kiln of oxygen. This reduced level of oxygen causes incomplete combustion of the fuel and raises the level of carbon inside the kiln. At high temperatures the carbon will bond with and remove the oxygen in the metal oxides used as colorants in the glazes. This loss of oxygen results in a change in the color of the glazes because it allows the metals in the glaze to be seen in an unoxidized form. A reduction atmosphere can also affect the color of the clay body. If iron is present in the clay body, as it is in most stoneware, then it will be affected by the reduction atmosphere as well. In most commercial incinerators, exactly the same conditions are created to encourage the release of carbon bearing fumes. These fumes are then oxidized in reburn tunnels where oxygen is injected progressively. The exothermic oxidation reaction maintains the temperature of the reburn tunnels. This system allows lower temperatures to be employed in the incinerator section, where the solids are volumetrically reduced. Planetary atmospheres [edit] The same principle applies to planets. Many scientists think the early Earth had a reducing atmosphere, along with Mars and Venus. This would have proven to be a good environment for to evolve the first photosynthetic metabolic pathways which gradually increased the oxygen portion of the atmosphere, changing it to what is known as an oxidizing atmosphere. With increased levels of oxygen, the evolution of the more efficient aerobic respiration might have been enabled, allowing animal life to evolve and thrive. Though most scientists conceive of the early atmosphere as reducing, a 2011 article in Nature found that cerium oxidation in zircon—which comprises the oldest rocks on Earth at roughly 4.4 billion years of age—was comparable to that of present-day lava. This observation implies that Hadean atmospheric oxygen levels were similar to those of today.</p>]]></content:encoded> <category><![CDATA[Nitrous Oxide]]></category> <link>https://rawgoods.org/NitrousOxide/oxidizing-atmosphere</link> <guid isPermaLink="true">https://rawgoods.org/NitrousOxide/oxidizing-atmosphere</guid> <pubDate>Wed, 17 Apr 2024 10:51:00 +0000</pubDate> </item> <item> <title>Nitric oxide precursors</title> <description>Pre-workout drinks which raise the levels of nitric oxide (NO) in your system are a craze with gym goers and athletes alike.

Pump" align="left" /><p>Pre-workout drinks which raise the levels of nitric oxide (NO) in your system are a craze with gym goers and athletes alike. The reason the so called pump you get when doing typical bodybuilding exercises combined with the ability to rep out a few more on all exercises. Contrary to anecdotal evidence, however, there is not much published research on the alleged effects of pre-workout intake of NO. The question to be asked is: do pre-workout supplements really bump up your blood NO levels? And, are they worth spending your hard-earned money on! Let us investigate! Chemistry of Nitric Oxide Nitric oxide or NO for short is a chemical released by the innermost layers of your blood vessels the endothelium; main function it serves is causing relaxation of the blood vessel walls resulting. This causes increased blood supply to the concerned organ or tissue. Not surprising then that NO is also known as the endothelium derived relaxing factor (EDRF) (Furchgott & Zawadzki, 1980). NO is synthesized from the amino acid l-arginine; the process requires the presence of oxygen, enzymes and co-factors like vitamins (Collier & Vallance, 1991). Thus, arginine (being the precursor of NO) is present in most pre-workout NO boosting supplement formulations. Physiological Roles of Nitric Oxide Some of the important physiological functions that nitric oxide serves are as follows (Thomas et al., 2008; Anderson, 2000; Salanova, Schiffl, Puttmann, Schoser, & Blottner, 2008): Increases blood flow owing to the relaxation of blood vessel walls (Furchgott & Zawadzki, 1980) Improved resistance to development of angina and other peripheral arterial diseases Enhances immune function (with decreased stickiness of the white blood cells as well as platelets)</p>]]></content:encoded> <category><![CDATA[Nitric Oxide]]></category> <link>https://rawgoods.org/NitricOxide/nitric-oxide-precursors</link> <guid isPermaLink="true">https://rawgoods.org/NitricOxide/nitric-oxide-precursors</guid> <pubDate>Wed, 10 Apr 2024 10:44:00 +0000</pubDate> </item> <item> <title>Aluminum oxide decomposition</title> <description>****Section 1 - Chemical Product And Company Identification **** MSDS Name: Aluminum Oxide, Activated, Acidic, for Column Chromatography, 50-200 Synonym: Aluminum Oxide; Morin Dyed.

Oxidation: \( I^- \rightarrow I_2 \) This is the oxidation half because the oxidation state changes from -1 on the left side to 0 on the right side. This indicates a gain in electrons. Reduction: \( MnO_4^- \rightarrow Mn^{2+} \) This is the reduction half because the oxidation state changes from +7 on the left side to +2 on the right side. This indicates a reduction in electrons. 2) In order to balance this half reaction we must start by balancing all atoms other than any Hydrogen or Oxygen atoms. Oxidation: \( 2I^- \rightarrow I_2 \) In order to balance the oxidation half of the reaction you must first add a 2 in front of the I on the left hand side so there is an equal number of atoms on both sides. Reduction: \(MnO_4^- \rightarrow Mn^{2+} \) For the reduction half of the reaction, you can notice that all atoms other than Hydrogen and Oxygen are already balanced because there is one manganese atom on both sides of the half reaction. 3) Balance Oxygen atoms by adding H2O to the side of the equation that needs Oxygen. Once you have completed this step add H+ to the side of the equation that lacks H atoms necessary to be balanced. Oxidation: \(2 I^- \rightarrow I_2 \) Because there are no Oxygen or Hydrogen atoms in this half of the reaction, it is not required to perform any kind of balancing. Reduction: \( MnO_4^- \rightarrow Mn^{2+} + 4 H_2O \) The first step in balancing this reaction using step 3 is to add4 H2O atoms in order to balance the Oxygen atoms with the 4 on the other side of MnO4- Reduction: \( MnO_4^- + 8 H^+ \rightarrow Mn^{2+} + 4 H_2O \) Now that the Oxygen atoms have been balanced you can see that there are 8 H atoms on the right hand side of the equation and none on the left. Therefore, you must add 8 H+ atoms to the left hand side of the equation to make it balanced. 4) Now that the two half reactions have been balanced correctly one must balance the charges in each half reaction so that both the reduction and oxidation halves of the reaction consume the same number of electrons. Oxidation: \( 2 I^- \rightarrow I_2 + 2e^- \) Because of the fact that there are two I's on the left hand side of the equation which a charge of -1 we can state that the left hand side has an overall charge of -2. The I on the left side of the equation has an overall charge of 0. Therefore to balance the charges of this reaction we must add 2 electrons to the right side of the equation so that both sides of the equation have equal charges of -2. Reduction: \( 5 e^- + 8 H^+ + MnO_4^- \rightarrow Mn^{2+} + 4 H_2O \) Looking at the left hand side of the equation you can notice that there are 8 Hydrogen atoms with a +1 charge. There is also a MnO4- ion that has a charge of -1. When we add these two charges up we can calculate that the left hand side of the equation has an overall charge of +7. The right hand side has an Mn atom with a...</p>]]></content:encoded> <category><![CDATA[Black Oxide]]></category> <link>https://rawgoods.org/BlackOxide/oxidation-reduction-reactions-examples</link> <guid isPermaLink="true">https://rawgoods.org/BlackOxide/oxidation-reduction-reactions-examples</guid> <pubDate>Sun, 31 Mar 2024 08:18:00 +0000</pubDate> </item> <item> <title>Chromium oxidation</title> <description>This page looks at some aspects of chromium chemistry required for UK A level (and its equivalents).
