Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol and if it is greener than using a Jones reagent. Sure enough camphor was made with a 4.03 g of unsublimed camphor and 0.08g of pure camphor with a 2 % yield (in moles). No melting

TITLE: Determination of Riboflavin by using UV-Vis spectrophotometry. ABSTRACT: The amount of Riboflavin in various brand of children multivitamins was determine by using UV-Vis spectroscopy instrument‚ the series of standard of riboflavin was prepared in order to determine the amount of the riboflavin in the sample of children multivitamins. The maximum amount of riboflavin was found in the Champs multivitamin that contains 0.1155 mg followed by Chewies 0.1131 mg and Scott’s 0.0672 mg. OBJECTIVES:

Neuroimaging in traumatic brain injury 1.COMPUTED TOMOGRAPHY (CT) : While severe and moderate traumatic head and brain injuries often mandate head CT‚ several clinical scales require specific criteria in determining the need for neuroimaging after a mild TBI. These include the New Orleans Criteria (NOC) and the Canadian CT Head Rule (CCHR).(45) Both are relatively straight forward and use seven criteria readily obtained in the setting and evaluation of mild TBI. A head-to-head comparison

has been in the development of ultra fast lasers and electrons for studies of dynamics in chemistry and biology‚ and he received the 1999 Nobel Prize for Chemistry for his studies of the transition states of chemical reactions using femtosecond’s spectroscopy. Femtochemistry is the branch of chemistry in which chemical reactions are detected as they occur and the reaction times are measured. Femtochemistry gets its name from the fact that these times are measured in femtoseconds. One femtosecond

Gold Nanoparticles for Diagnosis and Treatment of Cancer Abstract—Nanotechnology has been an extremely hot topic over the decade. It is the science‚ engineering and technology conducted at nanoscale. Two of the main applications of nanotechnology include material science and biomedicine. We have achieved great strides in applying nanotechnology to material science that is well justified by the decreasing size of electronics available in market. However we haven’t made a mark in biomedicine yet

5)A spectroscopy would provide the different colours of the stars that make up the colour to be seen by the naked eye. It would provide the energy level that is made up in the star and would also tell astronomers what elements a certain star is made of. 6)Electrons in the Bohr theory are in perpetual motion‚ which says the electrons are constantly accelerating and decelerating. As the electrons are moving inward and outward they are moving through different energy levels‚ known as orbitals. In
