GRAPHENE: Nano Material with Macro Potential Abstract With the advent of technological advances in searching new and efficient sources of energy‚ Graphene has been touted to be the next big thing in the areas of energy storage and conversion. Being 200 times more stronger than steel and having current density million times greater than copper (at room temperature)‚ or its intrinsic mobility is a hundred times greater than that of Silicon‚ or its specific area being 2630 (m2/g)

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Podzols In soil science‚ podzols (also known as podsols or Spodosols) are the typical soils of coniferous or boreal forests. They are also the typical soils of eucalypt forests and headlands in southern Australia. The name Podzol is derived from the Russian words pod = under and zola = ash. Characteristics of Podzol soils - Deep organic layer comprising L (litter)‚ F (fermenting organic matter) and H (humus) forest‚ less under moorland - An ash-grey‚ structure less‚ silica rich E or elluvial

Experiment VI: Oxidation of Isoborneol with Bleach Purpose: In this experiment‚ Green chemical procedures were applied to oxidize isoborneol to camphor using bleach (NaOCl)‚ rather than the tradition chromium-based oxidizing reagents. The camphor was then purified using the process of sublimation. Procedure: Using a 50-mL Erlenmeyer flask‚ 1.316 g (8.5 mmol) isoborneol and 1.0 mL (17 mmol) glacial acetic acid were stirred vigorously with a magnetic stir plate. A volume of 1.7 mL NaOCl

complex biological sample‚ or of similar synthetic chemicals from each other)‚ and manufacturing (e.g. during the production process of pharmaceutical and biological products).[1] Chromatography can be described as a mass transfer process involving adsorption. HPLC relies on pumps to pass a pressurized liquid and a sample mixture through a column filled with a sorbent‚ leading to the separation of the sample components. The active component of the column‚ the sorbent‚ is typically a granular material

Abstract In order to experiment with distinct components of a mixture‚ they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further
