    decomposes into water and oxygen upon heating or in the presence of numerous substances, particularly salts of such metals as iron, copper, manganese, nickel, or chromium. It combines with many compounds to form crystalline solids useful as mild oxidizing agents; the best-known of these is sodium perborate (NaBO2H2O23H2O or NaBO34H2O). With certain organic compounds, hydrogen peroxide reacts to form hydroperoxides or peroxides, several of which are used to initiate polymerization reactions. In most of

    Advanced Oxidation Process (AOP) AOP is based on production of very strong oxidizing species to treat toxic or hazardous organic and inorganic pollutant. Commonly, AOP is combination of strong oxidizing agent and ultraviolet light (Balcinglu et al., 2003). In industrial wastewater, the common oxidizing agent used to treat the wastewater is ozone. It is known that ozone is used to treat drinking water but it is quite new in wastewater treatment. Ozone has higher oxidation potential than chlorine thus

    Organic Hair Dyes Organic dyes in hair products and cosmetics have been used throughout history for many aspects of culture and art. Today organic dyes are used in the process of hair dying and colouring where many aspects of the organic molecule are taken into account. Some dyes are permanent where they stay until the hair falls out, where some dyes can be washed away due to their binding process into the hair1. Certain dyes have their own way of being set into hair fibres and easier ways to

    The “blue-bottle” experiment demonstrates a redox reaction. This is one of the most common reactions in chemistry. Redox reactions are the movement of electrons from one substance to another. The word “redox” comes from the concepts of reduction and oxidation. Reduction is the intake of an electron by an atom. Oxidation is the opposite. It is the loss of an electron by an atom. These two reactions go hand in hand because in a chemical reaction, one reaction cannot happen without the other. The blue

    THE Quality of Indoor Air has become increasingly important given that the amount of time spent indoors is more than ever before. Indoor Air has been found to be contaminated with microbials (including viruses, microscopic bacteria, fungi, etc.), harmful gases (like VOCs, radon, formaldehyde, H2S, etc.) and particulates (PMx , dust, etc.) that are responsible for “building related diseases”( US EPA, 1990; WHO 1989).

    Through an oxidation-reduction reaction sequence, Borneol is converted to isoborneol. First, borneol is oxidized through a reaction with sodium hypochlorite at 400C to form camphor. When the camphor is then reduced by sodium borohydride, isoborneol is formed. The percent yeild of isoborneol collected was 56.4%, and the melting point range was found to be between 174.2-179.90C. Through analysis of the product through 1H NMR spectroscopy the percent purity is found to be 77.2% pure isoborneol.

    Surface morphology of the prepared samples was investigated through SEM studies (Fig. 2). It is evident from Figs. 2(a) and (b) that PPy nanofibers of diameters about 63 and 51 nm are formed in the presence of HCl and HNO3, respectively. The PPy nanofibers formed in the presence of HCl (A1) are quite uniform and longer than the nanofibers prepared with HNO3 (A2), whereas, agglomerated structures without any definite shape and size have been observed with HClO4 (A3) and H2SO4 (A4).

    "Why is DsbA Such an Oxidizing Disulfide Catalyst?" Introduction The importance of the DsbA enzyme is due to its protein-folding ability in Escherichia coli bacteria. Protein is an essential part of all forms of life. Genes code for proteins, both structural and enzymes responsible for the utilization of other macromolecules. All bodily functions, therefore, are dependent upon proteins. Every protein, or polypeptide chain, uses the amino acid cysteine, which contain dithiol molecules. IN E

    reduced to two possible diastereomers, in which isoborneol was favored, with the use of sodium hypochlorite and sodium borohydride. Hypochlorous acid served as the oxidizing agent and was vital in the formation of the ketone making up the bicyclic compound Camphor. Second most important, sodium borohydride provided the reducing agent, hydride, which added in on the endo side of the second carbon (C2) to make the exo alcohol isoborneol. The mechanisms of oxidation and reduction mirrored similar reactions

    Fireworks How do fireworks produce their brilliant colors and loud bangs? To produce the noise and flashes, an oxidizer (an oxidizing agent) and a fuel (reducing agent) are used. The oxidizer oxidizes the fuel in a very exothermic reaction which produces a brilliant flash and a loud report from the rapidly expanding gases produced. For a color effect, an element with a colored emission spectrum is included. Electrons in atoms can be raised to higher-energy orbitals when the atoms absorb

    The film Stigmata & the Challenge of Conceptualizing Women as Spiritual Agents The history of Western religion has, for the most part been a history of men's religious stories, practices, and writings. It is quite rare and exceptional to find accounts of religion or practicing groups that place women's experiences at the center. Books, films, and various other cultural products bear this out by demonstrating a stubborn lack of attention to women's religious experiences. At first glance, the movie

    The Public Market - Company Managers Should be Public Actors Rather than Private Agents ABSTRACT: The marketplace as an institution enjoys widespread popularity today. Many economists hold that most of society’s problems could be best solved by applying the market mechanism to them. Government, by contrast, is widely considered to be a problem rather than a solution. Some would like to see the government restructured along market lines so that policies would follow voter choice, as products follow

    Humanity Educating Philosophy ABSTRACT: In what follows, I focus on the partiality and fallibility of each of us as individuals, and explore what that means for us as epistemic agents. When we examine the tradition of Western European thought, we note that most epistemological theories assume individuals can know the answer, and are able to critique what is passed down to others as socially constructed knowledge. Many have made the argument that while humanity can be deceived, one individual

    In her essay "Penelope as Moral Agent," Helene Foley attempts to discuss Penelope, a major character in Homer's the Odyssey, in terms of Classical Athenian portrayals of women and, as her title suggests, in terms of what she calls a "moral agent." In her introductory paragraph she lays out guidelines as set down by Aristotle and his contemporaries that constitute a moral agent: the character must make an ethical and moral decision "on which the actions turns...without critical knowledge of the circumstances"

Current shopping bots are more akin to metasearch engines. They do not fulfill a request, but merely return information in response to a query. At present, shopping bots have not reached the point where they are software agents, but everyone expects shopping bots to evolve into personal software agents as the

Although they speak of the future, they do not seem to affect the course of it. They are the agents of fate because they only speak of the truth of what will happen. There is one line in the play that has the most supernatural effect. “Fair is foul and foul is fair.” The theme that foul is fair and fair is fowl has the biggest supernatural pull
