Oxides

Properties).It is multidisciplinary area where in nanotechnology has led to major developments in health and medicine due to the integration the biotechnology in it (heralding new future-jyothi s a bhat). Nanoparticles such as silver, gold, zinc oxide and titanium oxide are being adopted as antimicrobials and additives in various aspects of consumers, health and industrial products(Nanoparticles and…

exhibited effervescence and was suspected to be sodium carbonate due to its solubility. The powders and crystals were divided depending on their solubility in deionised water. The two insoluble powders were suspected to be zinc carbonate and aluminium oxide. (6) was identified as zinc carbonate due to evolution of CO2 on addition of sulphuric acid. Among the soluble solids, two (1 and 12) formed precipitates in sulphuric acid. One was expected to be Barium chloride and to react with silver…

The researchers compared both biologically produced manganese oxides and chemically produced manganese oxides for the oxidation of diclofenac. Because biologically produced manganese oxides are known to have high specific surface areas and high catalytic reactivity, this substance offers higher rates of oxidation for diclofenac when compared to chemically produced manganese oxides.² If biologically produced manganese oxides prove to completely eliminate diclofenac from the water supply, the…

monoxide, hydrocarbons, nitrous oxides, carbon dioxide, and particulates. Carbon monoxide is a poisonous gas that is colorless and odorless. We have carbon monoxide detectors in our homes to ensure that there is not a fatal amount of this deadly gas in our own homes. Hydrocarbons react with nitrogen oxides and sunlight to form ground-level ozone, a major component of smog, which irritates the eyes, impairs lung tissues, and intensifies respiratory disease. Nitrogen oxides, like hydrocarbons,…

Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness,…

Everyone has heard of the impending doom of global warming. Over the last decade, most people have verbally expressed that it was a myth. Now, with the extreme transmutations in our climate, people are finally opening their eyes. The elevating temperatures and extreme weather patterns, pose the question, how could this have transpired? Well, let me tell you. Global warming is defined in Merriam-Webster’s dictionary as: the elevation in the earth’s atmospheric and marine temperatures…

Introduction Air quality refers to the condition of the air that surrounds us and good quality clean air is essential to the health and well being of humans as well as animal and plant life on this planet. Air pollution, caused either by humans or the natural environment, lowers air quality and in have severe health problems and in high enough concentration can cause death. For example, the World Health Organisation estimated in 2012, 7 million people world wide died prematurely due to the…

option that was nitrous oxide (N2O) but was still torn on what to prefer. This is an illustration of a problem that most pregnant women encounter before the birth of their…

Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…

number of minerals such as Dolomite (CaCO3∙MgCO3) and as Magnesite (MgCO3) [6]. Magnesium can be extracted from dolomite with the use of ferrosilicon (FeSi) The dolomite is heated, in air, this produces both magnesium oxides and calcium oxides. The mixture of magnesium and calcium oxides is then heated with the ferrosilicon which forms calcium silicate and magnesium [7] The extraction of magnesium from seawater is a completely different operation which relies on the fact that magnesium…
