Solid-phase synthesis

electronegative than halogen Y results in the formation of polarized covalent bonds. This experiment consisted of using experimental techniques to synthesize and decompose highly reactive, thus unstable, interhalogens that seemingly violate the octet rule. Synthesis reaction: KClO3 + I2 + 6HCl → KCl + 2ICl3 + 3H2O Decomposition reaction: I2Cl6 → 2ICl + 2Cl2 The halogens used within this experiment consisted of Iodine and Chlorine to produce an oxidizing reagent Iodine trichloride. Due to…

stabilizer. The influence of various experimental parameters such as % volume fraction of coir extract, concentration of metal precursor, contact time and solution pH on the formation of AuNPs was evaluated to determine the optimum conditions for synthesis. As synthesized AuNPs were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis…

use those skills in actual data collection and analysis. In part one we used a sample of sodium saccharinate combined with a sample of a metal halide salt, our group used copper(II) chloride. The combination of these two samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of fertilizer. This sample was then compared to the amount of phosphorus which was present in the NPK ratio…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

weightlifting team and so he became to experiment with the drug on the US weightlifting Team (Peter M.Miller et al, 2013 ). Methandienone has the benefits of giving the user a quick increase in lean muscle mass, strength and a an increase in protein synthesis with less negative effects than that of pervious steroids (Dbol Muscle Secret, 2016) . Drug usage was still occurring throughout a lot of sporting competitions and even with the call of a drug ban back in 1928 throughout sporting…

types [1]. Y zeolite is widely used as catalyst or catalyst support but a proper post treatment process such as dealumination should be carried out [2, 3] to increase Si to Al molar ratio to values over 3, which is not achievable through direct synthesis [4]. Zeolite dealumination was introduced regarding instability of the framework in acidic and aqueous media [5, 6], and could be conducted by acid extraction [7], Al/Si substitution [8] and thermal treatment of ion exchanged NaY zeolite [9].…

Abstract – Photocopiers make use of Toner (powder) to form the latent electrical image on the electrostatically charged drum. The paper has to slide over the drum during Xerography process and hence it picks up the toner. Vague issues cause the non-picking of toner particles (approximately 10%) and they are left over the drum. This non-picked toner is termed as Waste Toner (WT). As it adversely affects the quality of proceeding copies, this has to be removed from the drum. A cleaning blade made…

Vitamins are the organic compounds required to carry out a living body’s metabolism and their absence can clump several metabolic reactions in the body. These essential nutrients cannot be synthesized in the body therefore must be taken from an outside food source i.e. plants, fruits, vegetables or animals. Basically there are two types of vitamins in nature; some are water soluble and others are the fat soluble ones. Water soluble vitamins are those which are soluble only in water and are B…

When conducting a research on the dynamism of stakeholders and their power in construction projects, Sarah Nash, Ezekiel Chinyio, Rod Gameson, Subashini Suresh came across an interesting observation resulting in a solid list of external stakeholders in construction projects. The research pointed out that external landowners, local communities and businesses in the neighborhoods represented a stronghold in construction projects and therefore had a high or low influence…

lower silica content decreased obviously in comparison with resistance value (2671 Ωcm2) of the modified electrodes comprising MPS with higher amount of SiO2. These results were in agreement with the results from CVs. Meanwhile, since the Bode and Phase diagrams of the modified electrode had two peaks and inflection points, respectively two capacitive responses and resistances can be considered. Hence, in the quantitative interpretation of the EIS results, the Cc and RC are capacitance and…
