Synthesis of terpolymer PLGC: The terpolymer PLGC was synthesized using a reported procedure with a starting monomer ratio of 70:20:10 of L-LA‚ GL and Ɛ-CL respectively using the catalyst tin(II)2-ethyl hexanoate. The chemical reaction is given in the figure1. The yield % of the synthesized polymer was calculated by the equation: Yield %= (Weight of synthesized polymer)/(Weight of the monomers taken) ×100 Characterization of synthesized polymer: Chemical analysis using Fourier transform infrared

Then we address preventive treatment‚ disease-time treatment‚ and diagnosis in the context of some of the most recent advances in nano technology. Nanoparticle science is also briefly addressed as the foundation upon which most nanotechnology cancer therapy is based. It is demonstrated how nanotechnology can help solve one of the most challenging and longstanding problems in medicine‚ which is how to

Sophia Lopez Period Three February 3rd‚ 2017 Research Paper Outline I. Introductory Paragraph A. King Tut was the 12th king of the 18th Egyptian dynasty‚ in power from 1332 to 1323 B.C.E. After his death at age 19‚ he disappeared from history‚ until the discovery of his tomb in 1922. Since then‚ studies of his tomb and remains have revealed much information about his life and times. B. British archaeologist Howard Carter had begun excavating in Egypt in 1891‚ and after World War

Theory of Fighting Pathogens with Pathogens Is Homeopathy A Credible Treatment? Around 1790‚ Samuel Hahnmann‚ a German physician took in a certain amount of quinine from the bark of Cinchona sp. which was usually used to treat malaria (the main symptom is fever) and later he noticed some effects such as his body temperature raised. With further study‚ he concluded the theory that a substances cause disease symptom can also alleviate the disease which later developed to be “Homeopathy” treatment

Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

1.1 Definition Nanochemistry is concerned with generating and altering chemical systems‚ which develop special and often new effects as a result of the laws of the nanoworld. The bases for these are chemically active nanometric units such as supramolecules or nanocrystals. Nanochemistry looks set to make a great deal of progress for a large number of industry sectors. Nanotechnology exists in the realm where many scientific disciplines meet. Achievements in physics are getting progressively

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big
