  • Plutonium Violations

    39, ‘Safe Handling of Plutonium’ ( IAEA, 1998). Plutonium is a man-made radioactive element that is made from uranium in nuclear reactors (Environmental Protection Agency, 2014). Much of the plutonium made was to be used for nuclear war. When plutonium decays it releases radiation. So do the other forms of isotopes. The half-live of these…

  • Dystopia In Animal Farm By George Orwell

    “All animals are equal, but some animals are more equal than others.” This quote was written by George Orwell in his book Animal Farm, one of Orwell’s most famous novels. Throughout history the subject of a distant dystopia has always been explored in many works of literature. The possibility of humanity falling into a bleak and totalitarian society has always fascinated readers. These stories and themes can come to define an author and their legacy as a writer. There is no greater example of…

  • Ernest Rutherford's Atomic Model

    An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…

  • Negative Effects Of Carbon 14 Isotope

    An Isotope is an atom of an element which has a different number of neutrons and different mass number but the same proton number. The isotope that will be focused in the essay is carbon 14 isotope. Carbon is found in all living things and is the building block for organic material, there is carbon 12, 13 and 14 and they all have different properties. This isotope was discovered on February 27, 1940 by Martin Karmen and Sam Ruben and is the most radioactive out of all carbon isotopes. The…

  • How Nature Affects The Workplace Essay

    have been incorporating elements from nature as a decorative element since ancient times, but there hasn’t been any scientific data backing up the benefits of integrating nature into a space until recent times. Enabling the human connection to nature within an environment has been found to address the wellbeing of its occupants. Many urban-dwellers today have forgotten about their connection with nature and the natural world, and living in a world…

  • The Pros And Cons Of The Moonshine

    Lots of American farmers found themselves unable to make enough money to support their families. One of the main ingredients of Moonshine is corn. A farmer could take a subpar corn farm and turn it into a goldmine. Obviously the Government did not approve of this practice. There are a couple good reasons for the Government to oppose this practice. With underground Moonshine sales growing they were losing a large amount of tax revenue; secondly, there was no way to regulate production, and…

  • Role Of Purification In SA Precious Metals (SA Pty) Ltd.

    Introduction Silver, like gold, is found in a native state; frequently too it occurs as an alloy containing gold, which is recognized, when the silver is dissolved in nitric acid, as the black sediment or oxide of gold. Arsenic and antimony are found also alloyed with it. Several of the ores of lead and copper contain silver. As silver is a precious metal often used for coins, its mining has historically often been lucrative. As with other precious metals such as gold, newly discovered deposits…

  • Fepo4: The Reflection Of Transition And Tetrahedral Distortioning

    The space group for α-FePO4 is P3121, with the lattice symmetry being tetrahedral in shape. On the other hand, the space group for β-FePO4 is P6422, with the lattice symmetry being hexagonal in shape. In this writing assignment, FePO4 is studied at varying temperature ranging from 294K to 1073K by neutron powder diffraction. At a relatively low temperature, it adopts the structure of the α-quartz. However, at high pressures, it changes and it can be observed that it becomes a denser…

  • Differences And Similarities Between Dmitri Mendeleev And The Modern Periodic Table

    Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered them based upon increasing atomic weight. Another difference is that the modern periodic table has some elements that Mendeleev had not found. One of these family of elements are the non-reactive noble gases. There are also no gaps in the current Periodic Table. In Mendeleev’s version, he had gaps where elements had not been found yet. The last difference is that the…

  • How Is Fepo4 Formed From A Temperature Range Of 294K To 1073?

    Paragraph 1 The structural evolution of FePO4 studied from a temperature range of 294K to 1073K by neutron powder diffraction. It is unique from α-quartz isotopes. It is different because it’s a cation is a transition metal. The structure dimensions and atomic coordinates in the α phase tend to increase by great amounts as the high-temperature β-phase rises and exhibit first order transition at 980K. The atomic structure dimensions of the α-phase FePO4 increased in a non-uniform pattern with…
