skills about photonics. That’s why‚ TUBITAK ( Turkish National Scientific and Technical Research Center) Materials Institute was very good place for me‚ so I started to do my training there in Electron Microscopy and XRD-Spectroscopy Laboratories. In TUBITAK I focused on spectroscopy techniques‚ photonics systems‚ photonic detection and characterization. Compulsory official training time was 1 month but I extended the time to 5 months for my self. My training result was (AA – in German System 1.0) excellent

The discipline of archaeology is by no means a simple nor singular study of the past. Due to the wide range of evidence within the archaeological record‚ from organic to inorganic‚ many different methods and approaches are taken in order to deal with the wide spectrum of differing evidence. Nevertheless‚ the study of pottery is without doubt one of the most important tasks taken on by any archaeologist. A great wealth of information can be gained from the study of pottery‚ despite its inanimate state

Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

(2) ATOMIC ABSORPTION SPECTROSCOPY OF THE MIXTURE Experiment 4 Dates of Experiment: 10/14/08 through 10/30/08 Date of Report: 11/7/08 Chem 2262L � I. Introduction In this experiment‚ the zinc and nickel contents of unknowns were tested using two methods. In the first method‚ nickel and zinc were separated through ion-exchange chromatography and analyzed through chelometric titration. In the second method‚ the unknown was analyzed through the atomic absorption spectroscopy (AAS) of the mixture

of this experiment was to successfully prepare an endo‚cis-diacid from the synthesis of the bicyclic anhydride (cis-Norbonene-5‚6-endo-dicarboxylic anhydride). The percent yield of the product was calculated and found to be 39.01%. The infrared spectroscopy confirmed the presence of a O-H group with a stretch at 2948.03 1/cm and the presence of C=O with a stretch at 1698.93 1/cm. Melting point determination found the melting point range of the products to be 149.2-164.1 for the bicyclic anhydride

It must be noted that the actual undertaken procedure included a few differences from the ideal protocol. A total of 7 ml of extra water was added to the reaction before it was treated in the separatory funnel due to there being so much white precipitate that the mixture had turned to a paste as opposed to a liquid. The aqueous layer was accidentally not drained between adding the two different ether fractions‚ so the aqueous layer was drained after that and 10 ml of extra diethyl ether were added
