Question here is how is medicinal chemistry applied in thee most advanced centaury off technology, widgets and gadgets? This text is aimed to clarify just that. A pharmaceutical supplement is a compound also commonly called a `drug` but according to Goeltze(2000) who is a chemist at the University of Ukraine gave a general opinion in an interview, stating that many scientist dislike the term `drug` since society views the word with suspicion. With media headlines such as “drug trafficking In Namibia” or “Drug Addiction sweeps city streets”, this is hardly surprising .However, Medicinal Chemistry suggests that a distinction can be made between drugs which are...

..._____________________________________________________________________CHEM 100 LECTURE UNIT 1. FOUNDATIONS OF CHEMSITRY Chemistry is the study of matter and the changes it undergoes. Matter is anything that occupies space and has mass. Applications of Chemistry • Energy and the Environment • Fossil fuels • Solar energy • Nuclear energy Health and Medicine • Sanitation systems • Surgery with anesthesia • Vaccines and antibiotics Materials and Technology • Polymers, ceramics, liquid crystals • Room-temperature superconductors? • Molecular computing? Food and Agriculture • Genetically modified crops • “Natural” pesticides • Specialized fertilizers • • • Classification of Matter A substance is a form of matter that has a definite composition and distinct properties. An element is a substance that is composed of tiny particles called atoms. A compound is a substance composed of atoms of two or more elements chemically united in fixed proportions. Compounds can only be separated into their pure components (elements) by chemical means. A mixture is a combination of two or more substances in which the substances retain their distinct identities. Physical means can be used to separate a mixture into its pure components. Homogenous mixture – composition of the mixture is the same throughout. Heterogeneous mixture – composition is not uniform throughout. 1 |P a g e _____________________________________________________________________CHEM 100 LECTURE PROPERTIES OF MATTER...

...quantum yield and rate constant of fluorescence quenching of antracene by CCl4. Methods A solution of anthracene and another solution of CCl4 are made in ethanol and mixed and diluted to various concentrations. The fluorescence and absorption spectra of these solutions are measured using a UV-visible spectrometer and a fluorescence spectrometer. Then a solution of anthracene is prepared in cyclohexane. Again, the fluorescence and absorption spectra are obtained and served as a reference for all calculations. Procedure The procedure followed was given in the lab manual, Experiment 23, Photophysics of Anthracene: Absorption, Fluorescence, Quantum Yield, and Fluorescence Quenching Rate. J. F. Wójcik and T. S. Ahmadi, Experimental Physical Chemsitry, p. 189-199. Data A total of 10 solutions were made. Solution 1 was prepared by dissolving 0.0154 g of anthrancene in ethanol in a 100-mL volumetric flask. Solution 2 was prepared by dilution 1 mL of solution 1 in a 25-mL volumetric flask. Solution 2 was prepared by dilution 1 mL of solution 2 in a 25-mL volumetric flask. Then solution 4 was prepared by mixing 2 mL of the fluorescence quencher, CCl4, with ethanol in a 100-mL flask. Solutions A through F are prepared according to Table 23.1 in the lab manual. Finally, 0.0165 g of anthracene is dissolved in cyclohexane in a 100-mL volumetric flask (solution CH1). Then 1 mL of solution CH1 was diluted in a 25-mL volumetric flask with cyclohexane (solution CH2). Both fluorescence and absorption...

...Abstract: Fluorescence has many practical applications such as mineralogy and chemical sensors. In this experiment, the fluorescence spectrum of an organic dye, Fluorescein was obtained and compared with its absorption spectrum. It was found that Fluorescein has a maximum absorption wavelength at (486±2) nm and maximum fluorescence emission at (517±2) nm. The cause in the shift of the wavelength between the absorbed and the emitted photons, known as the stroke’s shift, was caused by the collisional and vibrational non-radioactive decay in which some of the energy from the absorbed photon is converted into heat to the surrounding molecules. Hence the emitted photons have less energy and longer wavelength as: E=hv (1) These processes occur before the fluorescence because they have a much shorter lifetime (10-12 s) compared to the lifetime of the fluorescence (10-8 s) and thus competes effectively with fluorescence. Introduction: The aim of this experiment is to obtain the absorption and fluorescence spectrum in the organic dye molecule, Fluorescein. First, the spectrum of a xenon lamp was obtained using a monochromator combined with a photomultiplier tube detector. Then a fluorescence dye was inserted between the xenon lamp and the detector in order to obtain the absorption spectrum of the fluorescein dye. The equipment set up was then altered to investigate the fluorescence spectrum of the dye. The absorption spectrum and the fluorescence spectrum...
