Lyotropic liquid crystals are realized from certain concentration of amphiphilic molecules, such as phospholipids, in water. The specific interactions in which water is involved are very important for model-membrane stability. Dipalmitoylphosphatidylcholyne (DPPC) model membranes have been studied by FTIR technique at different temperatures in the spectral range {2500 - 4000} cm(-1). A Gaussian deconvolution has been performed in order to study the water behaviour from the point of view of hydrogen-bond formation between water molecules and both the hydrophilic heads of phospholipids and the components of buffer solution. This study contributes to the understanding the mechanisms which assure the model membrane stability.

Temperature dependence of the phospholipids bilayers stability, studied by FTIR spectroscopy Severcan, Feride; Agheorghiesei, Catalin; Dorohoi, Dana-Ortansa (2008-03-01) The temperature induced modifications in the lipid bilayers in water were studied by using 2D-FTIR Correlation Spectroscopy. The spectral range analysed in this paper corresponds to symmetric and asymmetric stretching vibrations of the -CH2 groups from the acyl chains of DPPC. Autocorrelation peaks at 2916 cm(-1) and 2848.5 cm(-1) and asynchrone modifications in the spectral ranges 2916-3000 cm(-1) and 2848-3000 cm(-1) were evidenced. The revealed modifications indicate changes in the conformers of the hydr...
Shape Effects on the Structure and Response of the Polymeric Particles Synthesized from Cholesteric Liquid Crystal Templates Avşar, Deniz Işınsu; Büküşoğlu, Emre (2021-01-01) : Liquid crystals (LCs) have been shown to provide molecular templates for the synthesis of polymeric particles. Past studies have revealed the elastic effects to dominate internal configuration of the LC molecular templates for the sizes below 10 µm. Sacrificial microwells were used in this study to study the effect of shapes of the particles synthesized from the cholesteric liquid crystals on their structure and response. Specifically, mixtures of diacrylate based reactive (RM257) and nonreactive mesogens...
Temperature effects on the structural and optical properties of the TlInSe2xS2(1-x) mixed crystals (x=0.3) Omar, A.; Qasrawi, A. F.; Hasanlı, Nızamı (2017-11-15) In this work, we have studied the temperature effects on the recrystallization process and on the energy band gap of the TlInSe(2)xS(2(1 - x)) mixed crystals at the critical composition (x = 0.3) where structural phase transition from tetragonal to monoclinic takes place. Remarkable effect which included permanent recrystallization process, enlargements in the monoclinic crystallite size, decreases in the compressing strain and in the dislocation density as well as in the stacking faults and in the energy b...
Amino Acid Conjugated Spiropyrans: Synthesis and Photoisomerization Studies Şentürk, Bengi; Akdağ, Akın (2022-09-01) Among photo-switchable compounds, spiropyrans have attracted significant attention owing to their multi-responsiveness towards a change in the pH, solvent polarity, and temperature, along with light. Upon exposure to the external stimulants, the merocyanine form is obtained due to bond cleavage between spiro carbon and oxygen, which transforms the optically active spiropyrans into an achiral form. The back conversion of the resulting achiral merocyanine form to the spiropyrans brings about a racemic mixture...
Temperature dependence of the energy transfer from amorphous silicon nitride to Er ions Li, R.; Yerci, Selçuk; Dal Negro, L. (2009-07-27) The 1.54 mu m photoluminescence and decay time of Er-doped amorphous silicon nitride films with different Si concentrations are studied in the temperature range of 4 to 320 K. The temperature quenching of the Er emission lifetime demonstrates the presence of nonradiative trap centers due to excess Si in the films. The temperature dependence and the dynamics of the energy coupling between amorphous silicon nitride and Er ions are investigated at different temperatures using two independent methods, which dem...
