Raman spectra were recorded using a Renishaw InVia Raman spectrometer in the near infra red excitation line (785 nm) of a diode laser source. The instrument is equipped with Peltier cooled charge coupled device (CCD 576x400 pixels). A Leica DMLM microscope with a XYZ motorized stage with 200 and 500 magnification objectives is equipped to Raman spectrometer which can provide a sample irradiation diameter of up to 1 μm. A

to study in vitro the permeability of amorphous drug systems in different conditions. First‚ three complementary techniques are performed to characterize the crystalline and amorphous form of indomethacin. These techniques include IR spectroscopy‚ Raman spectroscopy and differential scanning calorimetry. Indomethacin is a compound belonging to class II of the BCS and is consequently a poorly water-soluble drug. The limiting step in order to have a good bioavailability is the dissolution step. Several

Amlodipine is a calcium channel blocker that acts on the cardiac muscle and its peripheral vessels. Acting on the myocardial cells‚ which are responsible for the conduction of the electric stimuli of the heart‚ Amlodipine causes a decrease of the myocardial contractility [1]. Amlodipine causes dilation of coronary and peripheral arteries which is an important treatment of hypertension‚ as well as increasing blood flow to the cardiac muscle which aids angina [2].

characterization of the examined wall paintings was carried out by means of optical microscopy (OM)‚ scanning electron microscopy (SEM) equipped with an energy dispersive X-ray detector (EDS)‚ X-ray diffraction analysis (XRD)‚ Fourier transform infrared spectroscopy (FT–IR) and the colorimetric characterization. The results revealed the characterization of the stratigraphic structure of wall decorations of the tomb and their chemical composition. The obtained results helped in identifying the chromatic palette

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
