Melatonin induces opposite effects on order and dynamics of anionic DPPG model membranes Sahin, Ipek; Severcan, Feride; Kazanci, Nadide (Elsevier BV, 2007-05-27) The temperature and concentration induced effects of melatonin on anionic dipalmitoyl phosphatidylglycerol (DPPG) multilamellar liposomes (MLVs) were investigated by using Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC). The results show that melatonin does not perturb the phase transition profile, while a decrease in the main transition temperature (T-m) is noticed at high melatonin concentrations (15, 24 and 30 mol Low concentrations of melatonin (3, 6 and 9 mol ...
ELECTROLUMINESCENT PROPERTIES OF CERTAIN POLYAROMATIC COMPOUNDS: PART 2-ORGANIC EMITTERS Türker, Burhan Lemi; Tapan, Alper; Gumus, Selcuk (Informa UK Limited, 2009-01-01) This review is based on the electroluminescent and optical properties of certain polyaromatics in OLEDs with special attention to their specific function in the emitting layer, performance and emissive color. DAD and TDAD dopants depending on their concentration in the emitting layer exhibit good efficiencies and color purity for blue emission. When copolyethers with diphenylanthracene emitting segments are used in a single layer diode, visible pure blue light (440 nm maximum) around 15-20V can be achieved....
Immobilization studies utilizing solid supports for the determination of fructose by dansylaminophenyl boronic acid (DAPB acid) and chromate by diphenylcarbazide (DPC) Bulut, Mukadder; Volkan, Mürvet; Department of Chemistry (2006) Immobilization of fluorescent chemosensors and chromogenic reagents on solid supports for developing optical sensors result in improved analytical performance characteristics such as continuous read-out, increased sensitivity, lower reagent consumption and possibility of using the sensor in solvents where the free molecule displays low solubility. The aim of this study is to immobilize dansylaminophenyl boronic acid (DAPB acid) and diphenylcarbazide (DPC) into various solid supports for the determination of...
Electrochromic and photovoltaic applications of benzotriazole bearing donor acceptor type conjugated polymers Baran, Derya; Toppare, Levent Kamil; Department of Chemistry (2010) Organic semi-conductors are of great interest since these compounds can be utilized as active layers in many device applications such as ECDs, LEDs and solar cells. Incorporating the benzotriazole units into the polymer backbone enhances the optical properties of donor units. Hexyl thiophene and pyrrole are commonly used as electron donor materials. Benzotriazole can be coupled to hexyl thiophene or pyrrole to yield materials which can be polymerized to give donor acceptor type polymers. These materials are...
Resonant frequency shifts related to the elastic constants near the alpha-beta transition in quartz Yurtseven, Hasan Hamit (Elsevier BV, 2019-03-05) The resonant frequency shifts of vibrational modes are related to the elastic constants at various temperatures for the alpha-beta transition in quartz (T-c = 573.0 degrees C for alpha-quartz and 574.3 degrees C for beta-quartz). This correlation is constructed on the basis of the spectroscopic modifications of the Pippard relations near the alpha-beta transition in quartz by using the observed data from the literature.
