Fourier transformed infrared spectroscopy (FTIR) has been employed to observe and understand structural variations in SiO2 matrix during the formation of Ge and Si nanocrystals by ion implantation as a function of processing parameters. The Si-O asymmetric stretching peak of absorption spectra were used to monitor the evolution of SiOx (x < 2) films during the annealing process. It was shown that the recovery process in Si-O network is quite different in Ge and Si implanted samples and the deformation caused by Ge atoms in the SiO2 matrix can be recovered by annealing the implanted samples at lower temperatures than that by Si atoms. This is in agreement with the formation kinetics of the Si and Ge nanocrystals in SiO2 as observed by Raman spectroscopy and photoluminescence measurements of the same samples.

Evolution of Vibrational Modes of SiO2 During the Formation of Ge and Si Nanocrystals by Ion Implantation and Magnetron Sputtering İMER, ALİ; Yerci, Selçuk; ALAGOZ, A. S.; KULAKCI, M.; SERINCAN, U.; FINSTAD, T. G.; Turan, Raşit (2010-01-01) Structural variations of SiOx matrix have been studied with Fourier Transform Infrared Spectroscopy (FTIR) during the formation of Si and Ge nanocrystal. Two frequently used methods, magnetron sputtering and ion implantation have been employed to form SiOx matrix containing excess Si and Ge. The Si-O-Si stretching mode has been deconvoluted to monitor the evolution of SiOx films during the annealing process. The integrated area and the shift in the SiOx peak positions are found to be well correlated with th...
The influence of gramicidin S on the thermotropic phase transition of dipalmitoylphosphatidylglycerol DPPG/GS systems: Experiment and computer model Stan, C; Cristescu, CP; Severcan, Feride; Dorohoi, D (2004-09-01) The paper presents experimental data recorded by Fourier Tran form Infrared Spectroscopy regarding the influence of the antimicrobial peptide gramicidin (GS) concentration on the thermotropic phase transition of dipalmitoylphosphatidylglycerol (DPPG) lipid bilayer membrane in DPPG/GS systems, as reflected in the change of the bandwidth of the symmetric stretching band of CH2. The samples were investigated cyclically in a temperature range between 26.5degrees and 61.1degreesC which includes the gel to liquid...
Effect of progesterone on DPPC membrane: Evidence for lateral phase separation and inverse action in lipid dynamics Korkmaz, F; Severcan, Feride (Elsevier BV, 2005-08-15) Interactions of progesterone with zwitterionic dipalmitoyl phosphatidylcholine (DPPC) triultilamellar liposomes were investigated as a function of temperature and progesterone concentration by using three non-invasive techniques namely Fourier transform infrared spectroscopy, turbidity at 440 nm, and differential scanning calorimetry. The results reveal that progesterone changes the physical properties of DPPC bilayers by decreasing the main phase-transition temperature, abolishing the pre-transition, broad...
Using artificially generated spectral data to improve protein secondary structure prediction from Fourier transform infrared spectra of proteins Severcan, M; Haris, PI; Severcan, Feride (Elsevier BV, 2004-09-15) Secondary structures of proteins have been predicted using neural networks from their Fourier transform infrared spectra. To improve the generalization ability of the neural networks, the training data set has been artificially increased by linear interpolation. The leave-one-out approach has been used to demonstrate the applicability of the method. Bayesian regularization has been used to train the neural networks and the predictions have been further improved by the maximum-likelihood estimation method. T...
Structural properties of an engineered outer membrane protein G mutant, OmpG-16SL, investigated with infrared spectroscopy Yilmaz, Irem; Yildiz, Ozkan; KORKMAZ ÖZKAN, FİLİZ (Informa UK Limited, 2019-05-31) The structural and functional differences between wild type (WT) outer membrane protein G and its two mutants are investigated with Fourier transform infrared spectroscopy. Both mutants have a long extension to the primary sequence to increase the number of beta-strands from 14 (wild type) to 16 in an attempt to enlarge the pore diameter. The comparison among proteins is made in terms of pH-dependent conformational changes and thermal stability. Results show that all proteins respond to pH change but at dif...
