    spectrum of probes L1 and L2 (40 μM) were investigated in the presence of metals ions in DMSO solvent. As shown in Fig. 1, Schiff base L1 exhibited absorption band at 269 nm, 310 nm, 323 nm and 347 nm; and L2 at 264 nm, 319 nm, 341 nm, 439 nm and 462 nm, that may be attributed to π-π* charge transfer transition. However, no remarkable changes were observed in absorption spectra after the addition of 1 equivalent various metal ions such as Ag(I), K(I), Li(I) Na(I), Co(II), Cu(II), Cd(II), Pb(II), Mg(II)

    Clayton J. Walp Mr. Morill American Lit. and Comp. 25 September 2017 Smoke Signals: Elements of Representation Natural elements will often be viewed as symbols to represent a cycle of life changing experiences that will ultimately change the character forever on a deeper, spiritual level than what scratches the surface. Going through life, major events that change that person’s sense of direction and demeanor, for better or for worse, can be visualized as an element. Anger, sadness, loss of hope

    The specificity of albumin binding experiment was to determine the binding interactions that occur between serum albumin and three synthetic dyes with the use of electrophoretic procedure. Whole blood, or plasma. Clots upon standing and if the clot is removed, the remaining straw colored fluid is called serum. The major protein in serum is albumin which functions as a carrier molecule for the transport of certain small molecular weight compounds in blood. Molecules that bind to serum albumin are

    fact, many people have never even heard of them. Lanthanum is one of these unsung elements. Although, quite often, one may live his entire life without ever hearing of this element, lanthanum is practically everywhere. Far from being a “rare earth” metal, as its name implies, it can be found in many places, from the bones that make up the human form, to the vegetables that make their meals. (1)(4) This poster will tell the fascinating history of lanthanum, some of the physical properties that

    We all know the saying, “Don’t judge a book by it’s cover.” Similarly, every element in the periodic table has its’ own story and its’ own unique meaning. However, the average high schooler simply associates these elements as something used in their chemistry classes. In fact, the elements seen on the periodic table actually have much more to do in our daily lives and in history than most people know. While giving a whole new perspective to the meaning of Chemistry, author Sam Kean successfully recounts

    Transition metals are a group of metals that are considered dense and have high melting and boiling points. They are located between the alkaline earth metals group and the boron group. The transition metals are characterized by the number of inner energy levels that are occupied by the atoms. They are then separated into 2 groups: d-type transition metals and f-type transition metals. D-type transition metals are mostly consisted of important metals (commercially) and the rare and unimportant metals

    Precious metals do not have their own group on the periodic table. They are arranged together on the table. These elements do have the same chemical properties, however they do not have their own classification. All of these metals do not rust, they are resistant to oxidation and corrosion and they only break down when they are in high temperatures. Gold (Au), silver (Ag), platinum (Pt), ruthenium (Ru), rhodium (Rh), palladium (Pd), iridium (Ir), and osmium (Os) all have similar properties and are

    drug which will meet all requirements by exploring and understanding the structure and reactivity of the molecule. It is specifically focused on transition metal-based anticancer drug. Transition metals have unique properties and reactivity. They have different oxidation state which able them to interact with molecules of different negative charges. The metals are co-ordinated by different ligands which contribute to different chemical properties. The common anticancer drug produced is platinum-based
