Keystone Pipeline Project The United States is a fossil fuel hungry nation whose economy‚ markets‚ and transportation is highly dependent on the abundance of crude oil and petroleum. Although there is roughly 85.9 billion barrels of undiscovered technically recoverable crude oil currently in the form of oil shale located beneath our soil‚ we still rely on imports from foreign countries. With a crude oil and petroleum product net import of 7‚270 thousand barrels per day the United States is one

spectroscopy. The unknown ketone is from a homologous series of methyl ketones. CH3CO (CH2) nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin layer chromatography. The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction

An early observation of fluorescence was described in 1560 byBernardino de Sahagún and in 1565 by Nicolás Monardes in theinfusion known as lignum nephriticum (Latin for "kidney wood"). It was derived from the wood of two tree species‚ Pterocarpus indicus andEysenhardtia polystachya.[2][3][4][5] The chemical compound responsible for this fluorescence is matlaline‚ which is the oxidation product of one of the flavonoids found in this wood.[2] In 1819 Edward D. Clarke[6] and in 1822 René Just Haüy[7] described

Polyvinylchloride (PVC) film and sheets are used in a variety of application especially for packaging because their permeability‚ transparency‚ tear and impact properties are important. The effect of unmodified and titanate treated nano-CaCO3 on the microstructure as well as on the mechanical‚ barrier‚ optical properties of PVC films‚ prepared by solution casting method were studied. The tensile strength and barrier properties of nano-CaCO3/PVC increase with increasing loading of CaCO3 nanoparticles
