Modulation of the solvent-dependent dual emission in 3-hydroxychromones by substituents
Klymchenko, AS; Pivovarenko, VG; Ozturk, T; Demchenko, AP (2003-01-01)
3-Hydroxychromones (3HCs) are fluorescent dyes, which respond to solvent perturbations by shifts and changes in the relative intensity of the two well-separated bands in the emission spectra. These bands originate from an excited state intramolecular proton transfer (ESIPT) reaction, which can be modulated by different factors, including modi. cations in the 3HC chromophore. In view of the great importance of 3HCs as prospective basic elements of molecular sensors, we have performed the first systematic stu...
Modulation of frontogenetic plankton production along a meandering jet by zonal wind forcing: An application to the Alboran Sea
Oguz, Temel; Mourre, Baptiste; Tintore, Joaquin (2017-08-01)
We present a coupled physical-biological modeling study to elucidate the changes in ageostrophic frontal dynamics and the frontogenetic plankton production characteristics of a meandering jet under the impacts of successive westerly/easterly wind events combined with seasonal variations in the upstream transport and buoyancy flux characteristics of the jet, using a case study for the Alboran Sea (Western Mediterranean). Their nonlinear coupling is shown to result in different forms of physical and biologica...
Controlling the photoconductivity: Graphene oxide and polyaniline self assembled intercalation
Vempati, Sesha; Ozcan, Sefika; UYAR, Tamer (2015-02-02)
We report on controlling the optoelectronic properties of self-assembled intercalating compound of graphene oxide (GO) and HCl doped polyaniline (PANI). Optical emission and X-ray diffraction studies revealed a secondary doping phenomenon of PANI with -OH and -COOH groups of GO, which essentially arbitrate the intercalation. A control on the polarity and the magnitude of the photoresponse (PR) is harnessed by manipulating the weight ratios of PANI to GO (viz., 1: 1.5 and 1:2.2 are abbreviated as PG1.5 and P...
Analysis of nanoparticle Transmission Electron Microscopy data using a public-domain image-processing program, Image
Woehrle, GH; Hutchison, JE; Özkar, Saim; Finke, RG (2006-01-01)
The need to easily and quickly count larger numbers of nanoparticles, in order to obtain statistically useful size and size-distribution data, is addressed via the use of a readily available, free, public-domain program for particle counting, NIH-Image (and 2 others derived from it, Scion Image and Image J), collectively referred to herein as Image. The best protocols that we have found useful for the use of Image are reported; both appropriate as well as problematic applications of Image are then illustrat...
Ternary nanocomposites of low density, high density and linear low density polyethylenes with the compatibilizers E-MA-GMA and E-BA-MAh
Işık Coşkunses, Fatma; Yılmazer, Ülkü; Department of Chemical Engineering (2011)
The effects of polyethylene, (PE), type, compatibilizer type and organoclay type on the morphology, rheological, thermal, and mechanical properties of ternary low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE), matrix nanocomposites were investigated in this study. Ethylene – Methyl acrylate – Glycidyl methacrylate terpolymer (E-MAGMA) and Ethylene – Butyl acrylate- Maleic anhydrate terpolymer (E-BA-MAH) were used as the compatibilizers. The organo...
