Publication Metadata only Genetic disruption of nucleoside transporter 4 reveals its critical roles in malaria parasite sporozoite functions.(2022-08-24T00:00:00Z) Deveci, GÖZDE; Kamil, Mohd; Kina, Umit; Temel, Binnur Aydogan; Aly, Ahmed S I; DEVECİ, GÖZDE; KAMIL, MOHD; KINA, ÜMİT YAŞAR; TEMEL, BİNNURPublication Metadata only Thermally curable main-chain benzoxazine prepolymers via polycondensation route(2013-02-01T00:00:00Z) Demir, Kubra Dogan; Kışkan, Barış; Aydogan, BİNNUR; Yağcı, Yusuf; TEMEL, BİNNURPolybenzoxazines are addition-cure thermosetting polymers exhibiting versatility in a wide range of applications due to their good mechanical properties, dimensional stability, chemical resistivity, flame resistance property phenolic or epoxy resins have myriad applications in diverse fields starting from commodity materials to high technology aerospace industries. In this paper, we present synthetic strategies to incorporate thermally curable benzoxazine functionality into polymers as main-chain fashion in order to further improve various properties. The strategies successfully employed including monomer synthesis and polycondensation routes like Mannich reaction, click chemistry, hydrosilylations, and coupling reactions. The structure-property relationships of the cured materials have also been presented and discussed. (C) 2012 Elsevier Ltd.

Subsequently, pyrene possessing polymeric nanoparticles are attached onto multiwalled carbon nanotube (MWCNT) surfaces by pi-pi stacking strategy. Gel permeation chromatography, thermal gravimetric analysis, ultraviolet-visible, and fluorescence spectroscopies are used to analyze modified nanoparticles and their precursors. Electron microscopy and dispersion studies show that pyrene-modified polymeric nanoparticles are able to interconnect various CNTs. (c) 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 2709-2714Publication Metadata only Long wavelength photoinitiated free radical polymerization using conjugated thiophene derivatives in the presence of onium salts(2011-01-01T00:00:00Z) Beyazit, Selim; Aydogan, BİNNUR; Osken, Ipek; Öztürk, Turan; Yağcı, Yusuf; TEMEL, BİNNURLong wavelength free radical photopolymerization of (meth) acrylic monomers using a conjugated thiophene derivative, namely 3,5-diphenyldithieno[3,2-b: 2-,3--d]-thiophene (DDT) and one of the following compounds, namely diphenyliodonium hexafluorophosphate (Ph(2)I(+)PF(6)(-)), triphenylsulfonium hexafluorophosphate (Ph(3)S(+)PF(6)(-)) and N-ethoxy-2-methylpyridinium hexafluorophosphate (EMP(+)PF(6)(-)), as photosensitizer and coinitiator, respectively, was described. Polymerization occurred only when DDT, in the presence of the onium salts, was irradiated at wavelengths where the salts have no absorption. A feasible initiation mechanism involves intermolecular electron transfer from photoexcited thiophene compound to the onium salt. The relative initiation efficiencies of the salts were investigated and evaluated in terms of their redox potentials.Publication Metadata only Single Dose Mixed Species Malaria Vaccination of Genetically Attenuated Blood Stage Malaria Parasites Induce Sterile Immunity Against Lethal Challenge by Both Species(2021-09-13T00:00:00Z) Deveci, Gözde; Temel, Binnur; Aly, Ahmed Sayed Ibrahım; DEVECİ, GÖZDE; TEMEL, BİNNUR; ALY, AHMED SAYED IBRAHıMPublication Metadata only Covalent Immobilization of Furanone Derivatives for the Inhibition of Biofilm Formation on Implant Surfaces(2018-04-01) Yelboğa, Emrah; TEMEL, BİNNUR; Karagüler, Nevin Gül; Tüter, Melek; TEMEL, BİNNURPublication Metadata only Polysiloxane-Containing Benzoxazine Moieties in the Main Chain(2010-11-15T00:00:00Z) Aydogan, BİNNUR; Sureka, Dilek; Kışkan, Barış; Yağcı, Yusuf; TEMEL, BİNNURPolysiloxanes containing thermally curable benzoxazine units in the main chain have been synthesized. For this purpose, first the diallyl functional benzoxazine monomer is synthesized through the Mannich and respective ring closing reactions of 4,4--isopropylidenediphenol (bisphenol A), formaldehyde, and allyamine. Subsequent hydrosilylation reaction of the resulting allylic monomer (B-ala) with 1,1,3,3-tetramethyldi-siloxane (TMDS) in the presence of Pt catalyst yields the corresponding oligo(B-ala-tetramethyldisiloxane)s (OBTMDS). Using the anionic polymerization route, OBTMDS was then converted to poly(bisbenzoxazinedimethylsiloxane)s (PBDMSs) by reacting with readily available cyclic oligomer octamethylcyclotetrasiloxane (D4) or decamethylcyclopentasiloxane (D5) in the presence of tetrabutylammonium hydroxide as catalyst. The structures of the precursor diallyl monomer, the intermediate oligomer, and the resulting polymers are confirmed by Fourier transform infrared and H-1 NMR analysis. Curing behavior of the products at various stages has also been studied by differential scanning calorimetry. Flexible transparent films of the PBDMSs are obtained by solvent casting. Thermal properties of the cured polymers are also investigated by thermogravimetric analysis. (C) 2010 Wiley Periodicals, Inc.

Its capability to act as caged one-component Type II photoinitiator for free radical polymerization was examined. Upon irradiation, this photoinitiator releases 5-benzoyl-1,3-benzodioxole possessing both benzophenone and 1,3-dioxole groups in the structure as light absorbing and hydrogen donating sites, respectively. Subsequent photoexcitation of the benzophenone chromophore followed by hydrogen abstraction generates radicals capable of initiating free radical polymerization of appropriate monomers.
