Need an research paper on russian scientists’ contribution to the world science. Needs to be 5 pages. Please no plagiarism. It was stated that Mendeleev derived the Periodic table in his dreams. Mendeleev had the vision of the Periodic table in his mind but unable to put them into table. He worked continuously for three days to create the table. Ultimately he slept in his table and had a dream of the arranging the 63 elements in the Periodic Table of Elements. Then he wakes up from the dream and derived the table that he dreamt. It was perfectly correct with only a few corrections made in it. It took nearly 20 years to construct this precious table and his contribution helped greatly to learn the characteristics and property of the elements. Later he discovered Gallium, Scandium and Germanium. He worked as a professor at the St. University of Petersburg from 1868 to 1890. His other studies and contributions areThe derivation of 40° vodka formula was really an interesting story. It was the time world over running researches on weight analysis on alcoholic solutions. Mendeleev received the accurate results by missing the alcohol with water-based on weights while the whole other world used to mix by volumes. Then he formulated as the precise content of spirit in vodka to be 40°. Upon reciprocal dilution the largest compression a mixture can be made. That is 45.88% of anhydrous spirit can be mixed with 54.12% of water. To explain this exactly 1 litre of 40° vodka weights 951 grams exactly (Allaby & Gjertsen, 2002).Lebedev was born in 1834 in Lubin. He completed his graduation at St. Petersburg University. After his graduation, he moved from university to university in charge of the work and finally settled down at the Petersburg Margarine Factory (Encyclopedia Britannica Inc, 2002). His main works are devoted to the invention of the polymerization of the hydrocarbons of ‘diene’ type. He was the first to produce the polybutadiene&nbsp.synthetic rubber. This synthetic rubber replaced the natural rubber and was produced during World War I as there was a shortage of natural rubber.&nbsp. His wrote a book named as ‘Research in the polymerization of by-ethylene hydrocarbons’ in 1913, which became the basics guide for studies on synthetic rubber.&nbsp.
