RAMAZANOV Baku State University‚ Baku‚ Azarbaijan E-mail: mamed_r50@mail.ru Several composites have been studied for static dissipationand microwave absorbing materials based on polyaniline with metallic oxides. These composites which are conducting polymers have been widely used because of their lower density as well their good environmental stability as in

of MPTP dramatically accelerates this process in the course of days and not years (Hanson et al.‚ 2015). Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it forms MPP+ which is toxic. Toxic oxidation later reaches the extracellular fluid and

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared

FREEDOM Freedom. Isn’t that such a beautiful word. A luxurious gift we’ve been given. A feeling many people would like to experience. We have a right as people living in the United States of America to have and experience freedom. But did we ever really take the time to think of what freedom really means and how lucky we are to have such a thing. Freedom has such a great meaning and value to me because I know what it is like to have no freedom. To me freedom is much more than just being able

Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Huckleberry Finn: Morality vs Society Morality is what sets humans apart from the animal kingdom. We act on our beliefs‚ instead of our instincts‚ which perhaps makes us the flawed species. As humans‚ we all develop our own set of morals of which we use to make decisions in our day to day life. We use this moral compass to differentiate between right and wrong‚ but what we see as the right thing to do is not necessarily our own opinion‚ but societies.

Title IX Title IX creates an inefficient bureaucracy that fails to address the real causes of sexism and instead creates problems in regulations and further inequalities. Title IX provides opportunities to female athletes‚ but at the expense of lesser known male sports teams. Title IX‚ like many other laws‚ has good intentions but lacks the resources to support it. It is not right that the University of Minnesota "axed its trophy winning men’s gymnastics team‚" (Source A) simply because it needed
