A comparison of fluorescence and UV-visible spectrometry techniques for thermal phase transitions of agarose gels
Arda, Ertan; Kara, Selim; Mergen, Ömer Bahadır; Pekcan, Önder (Springer, 2015)In this study thermoreversible phase transitions of high (HMP) and low (LMP) melting point agarose gels were investigated by using the UV-vis and fluorescence spectroscopy techniques. Pyranine was added to the aqueous ... -
Effects of GNP addition on optical properties and band gap energies of PMMA films
Mergen, Ömer Bahadır; Arda, Ertan; Kara, Selim; Pekcan, Önder (Wiley, 2019)In this study the effects of graphene nanoplatelet (GNP) doping on the optical parameters (absorption coefficient alpha and extinction coefficient k) and the optical transition energies (optical band gap and Urbach energies) ...
