Miscibility of methylmethacrylate-co-methacrylic acid polymer with magnesium, zinc, and manganese sulfonated polystyrene ionomers
Alkan, C; Yurtseven, N; Aras, L (2005-01-01)
The miscibility of methyl methacrylate-co-methacrylic acid polymer (MMA-MAA) with metal neutralized sulfonated polystyrene ionomers was investigated by viscometry, differential scanning calorimetry (DSC), and Fourier transform infrared radiation spectroscopy (FTIR) techniques. Polystyrene (PS) was sulfonated by acetic anhydride and sulfuric acid and the sulfonation degree was found to be 2.6 mole percent, and 2.6 mole percent sulfonated polystyrene was neutralized by Mg, Zn, and Mn salts. The miscibility be...

Miscibility of polystyrene-based lonomers with poly(2,6-dibromo-1,4-phenylene oxide)
Alkan, C; Aras, L (2001-12-27)
Blends of poly(2,6-dibromo-1,4-phenylene oxide) (PDBrPO) with 4.8 mol % sulfonated polystyrene (4.8SPS), Na-neutralized 1.7 mol % sulfonated polystyrene (Na1.7SPS), Mn-neutralized 3.8 mol % sulfonated polystyrene (Mn3.8SPS), and Zn-neutralized 3.8 mol % sulfonated polystyrene (Zn3.8SPS) ionomers were investigated for their miscibilities with varying compositions by dilute solution viscometry (DSV), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). Deltab, mu, and alpha paramet...
Misorientation and grain boundary orientation dependent grain boundary response in polycrystalline plasticity
Yalçınkaya, Tuncay; Tandoğan, İzzet Tarık (2021-02-01)
This paper studies the evolution of intergranular localization and stress concentration in three dimensional micron sized specimens through the Gurtin grain boundary model (J Mech Phys Solids 56:640-662, 2008) incorporated into a three dimensional higher-order strain gradient crystal plasticity framework (Yalcinkaya et al. in Int J Solids Struct 49:2625-2636, 2012). The study addresses continuum scale dislocation-grain boundary interactions where the effect of crystal orientation mismatch and grain boundary...
Covalent and noncovalent functionalization of pristine and defective graphene by cyclohexane and dehydrogenated derivatives
Sayin, Ceren Sibel; Toffoli, Daniele; Toffoli, Hande (2015-10-01)
The interaction of cyclohexane (C6H12), cyclohexyl (C6H11*) and cyclohexene (C6H10) with both pristine and defective graphene (single vacancy and a carbon adatom), is systematically investigated within the density functional theory framework. C6H12 physisorbs on both pristine and defective graphene while C6H10 chemisorbs on graphene in the presence of an adatom. The C6H11* radical binds covalently with the graphene substrate in all adsorption geometries considered.
