Description of Scientific Interests Environmental Technology and Energy Technology‚ the two strongly connected‚ and very much socially relevant interdisciplinary fields have inspired me a lot right from my school days. My bachelors and masters in the broad fields of Biotechnology & Biochemical Engineering and Biotechnology & Bio-reaction Engineering‚ respectively‚ have prepared me well enough for pursuing further in the fields of Environmental Technology and Energy Technology. I have been very

EXPERIMENT 4 ANALYSIS OF HYDROCARBON IN COMMON FUELS BY SOLID-PHASE MICROEXTRACTION (SPME) AND GAS CHROMATOGRAPHY-MASS SPECTROMETRY (GC-MS) Abstract In the analysis the solid-phase microextraction (SPME) and capillary gas chromatography/mass spectrometry (GC/MS) was developed for the identification of volatile compounds (hydrocarbon) in fuel. The samples was used is (kerosene‚ diesel‚ thinner and petrol) and one unknown. After the analyte was extracted by SPME in 20min‚ it directly injected

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

respiratory pigments; these pigments are metal containing proteins which combine reversibly with oxygen. Respiratory pigments are found within cells of blood and their primary function is to aid in the transportation of molecular oxygen. There are four unanimously recognised respiratory pigments‚ these are; hemoglobin‚ followed by hemocyanin‚ then chlorocruorin and Hemerythrin. These four pigments occur in greater percentages and are far more efficient in carrying oxygen than the few other pigments known

The energy is traveling through pigments until the it reaches the reaction center. To boost the electron to a high level the energy would transfer to p680. After the energy being transferred its then passed to an acceptor molecule which would replace an electron from water. O2 would be

geochemistry has played an important role in many areas of exploration and production for fossil fuels. Many of the more recent developments can be seen to have developed in parallel with developments in analytical chemistry such as gas chromatography and gas chromatography−mass spectrometry. For the past two decades such analytical techniques have been used to search for trace amounts of compounds known as biomarkers present in oils and source rock extracts which can be used to provide valuable information

effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to leak out by diffusion. Biological principle: The cell membrane is mainly made up of phospholipids and proteins. The phospholipid

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One
