BAND THEORY OF SOLIDS According to quantum free electron theory of metals‚ a electron in a metal experiences constant(or zero) potential and free to move inside the crystal but will not come out of the metal because an infinite potential exists at the surface. Bloch Theorem: According to this theorem‚ the periodic potentials due to the positive ions in metal have been considered. (i.e. the electrons moves in a periodic potential provided by lattice). If the electron moves through these ions‚

Liquid CO2 Extraction of D-Limonene This convenient‚ effective and inexpensive liquid CO2-based extraction of a natural product (D-limonene) provides an engaging example of natural products extraction using an alternative solvent (liquefied CO2). Because the procedure can be carried out in a polypropylene centrifuge tube and uses crushed dry ice as its CO2 source‚ it provides an inexpensive alternative to the equipment-intensive extraction with supercritical CO2. A short video clip is available

The blame repeatedly falls on the shoulders of procrastination. It usually plays out like this… “I will start my essay now… After I get on facebook.” This is usually just the beginning. Social media and networking end in a night of catching up with old friends‚ reading countless of stories from less than reputable sources‚ and somehow

Micro-extraction of urine and/or stomach contents and analysis by TLC Abstract Thin Layer Chromatography (TLC) is one of the oldest chromatographic techniques used for the identification of compounds and for determination of the presence of trace impurities. The aim of the experiment was to determine two unknown samples (X and Y) by comparing results to the known standard drugs‚ of which there was five‚ using a specific TLC method. The same technique was used for the determination of

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because they
