In order to synthesize our metal complexes, we were able to make both Copper and Ruthenium metals. From this, we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum, it was determined that S=O shifted to a lower wavenumber in CuCl2~2DMSO and that S=O shifted to a higher wavenumber in RuCl2~4DMSO.

The Lithium Nickel Manganese oxide battery is still in its experimental stages. It consists of a 25% nickel substituted in a LiMn2O4 spinel. This is because Manganese will have 4 electrons in its valence shell which will avoid the Jahn-Teller distortion caused due to the Mn3+. Due to the oxidation or reduction of Nickel ions which leads to the transfer of electrons which corresponds to electric current. LiNi0.5Mn1.5O4 takes shape in two conceivable crystallographic structures concurring the cationic sub lattice: the face-focused spinel (S.G. Fd3m) named as "cluttered spinel" furthermore, the straightforward cubic stage (S.G. P4332) named as "requested spinel". This addition allows

The rare earth mineral/element yttrium is a soft-silvery, crystalline transition metal, which is naturally found stable in the half-life isotope form of 89Y (1). The element is found on the periodic table in group 3, and period 5, with an atomic number of 39, and can be considered ductile, odorless, lustrous, fairly reactive, and soluble in hot water (1, 2). Not only does this element have a hexagonal crystal structure, it has an atomic mass of 88.906u, has melting point of 1522°C, and a boiling point of 3338 °C(1-3). Yttrium is available in many different compounds, and forms just alone in metal (2, 3). Some of these forms include, but not limited to metal balls, turnings, wire, rocks, ribbon, rings,

The rarest resources are the metals that the use for the electrical

Seaborgium is the element I will be teaching you about in this research paper today. Seaborgium is a element that not a lot of people completely understand. Seaborgium is a man made element that is radioactive, so it is kind of hard to study. For example the electronegativity according to pauling is unknown, the density, melting point, boiling point and ionic radius is unknown.

The synthesized pellets of La1-xSrxMnO3, (x=0.3, 0.4 and 0.5) manganites are shown in figure

Another 30 artificial radioisotopes of tungsten have been characterized, the most stable of which are 181W with a half-life of 121.2 days, 185W with a half-life of 75.1 days, 188W with a half-life of 69.4 days, 178W with a half-life of 21.6 days, and 187W with a half-life of 23.72 h. Tungsten typically combines with oxygen to form the yellow tungstic oxide, WO3, which dissolves in aqueous alkaline solutions to form tungstate ions,

One of the key differences of the two elements were how they were discovered. For example, according to the article “Tales of Technetium” by Eric Scerri, the element

In order to explore novel physical properties and phenomena and realize potential applications of nanostructures and nanomaterials, the ability to fabricate and process nanomaterials and nanostructures is the first corner stone in nanotechnology. There exist a number of methods to synthesize the nanomaterials, which are categorized in two techniques “top down and bottom up”. Solid state route, ball milling comes in the category of top down approach, while wet chemical routes like sol-gel, co-precipitation, etc. come in the category of bottom up approach. Secondly, characterization of nanomaterials is necessary to analyze their various properties. Therefore, this chapter describes the various methods of synthesis and characterization of nanomaterials. Characterization techniques include XRD, SEM, TEM, EDAX, UV-Visible spectroscopy, FTIR spectroscopy, etc.

In hardware it used to be used for the most part for electrical contacts however most now goes into chip resistors. In the substance business it is utilized as a part of the contacts for chlorine creation in electrochemical cells. Ruthenium is one of the rarest metals on the earth and is found as the free metal. Ruthenium is very contaminated and extremely hazardous to be around. Some of the compounds of ruthenium stain our skin and is reserved strongly in our bones. Ruthenium 106, one of its isotopes was used in testing the atmosphere of nuclear weapons, in the mid-1940s with a U.S. test and ended with a Chinese test. It’s one of those radionuclides that have and continue to produce improved cancer

Francium is the most reactive metal. When an atom reacts, it either loses or gains electrons. You can compare the reactivity of atoms by observing how readily they react. The 2 most important things that affect the reactivity of a metal are the atomic radius and the ionization energy. Atomic radius is the distance between the outermost electron and the nucleus, and the ionization energy is the energy required to remove the most loosely-held electron, turning it into an ion. The larger the atomic radius, generally, the lower the ionization energy, and the more readily the atom will react. The distance between two charges is more important to the strength of the attraction than the magnitude of the charges. According to our lab, potassium sparked a violent fire in water, which was more

Scandium is a transition metal but it was considered to be a rare earth element as its chemical properties were similar to other rare earth elements, the group Scandium belongs to is group 3, d-block and its period number is 4.

orbital contribution and (iii) the GdII exhibits the largest single-ion spin (S = 7/2) arising from the 4f7 electron configuration. (iv) Although MnIII ion possesses magnetic anisotropy due to Jahn-Teller distortion, it exhibit a comparatively high spin (S =2) and a large maximum entropy value calculated as Rln(2SMn + 1)/MMn = 271 Jkg-1K-1). In view of the above considerations compound 1 could be a good aspirant for magnetic coolers properties.
