Atomic Fe on hierarchically ordered porous carbon towards High-performance Lithium-sulfur batteries
Chen, Xinan; Zhu, Zhengju; Vargun, Elif; Li, Yiwen; Saha, Petr; Cheng, Qilin (Elsevier B.V., 2023)Lithium-sulfur (Li-S) battery is the promising next-generation energy storage device owing to its ultra-high theoretical energy density and low cost. Unfortunately, its practical performance is significantly hindered by ... -
Biodegradable porous polylactic acid film as a separator for supercapacitors
Vargun, Elif; Ozaltin, Kadir; Fei, Haojie; Harea, Evghenii; Vilcakova, Jarmila; Kazantseva, Natalia; Saha, Petr (Wiley, 2020)A porous polylactic acid (PLA) film was investigated as a separator for supercapacitors (SCs) and compared with commercial separators, for example, NKK-MPF30AC and Celgard 2400. The porous PLA film was fabricated via a ... -

Vargun, Elif; Sankir, Mehmet; Usanmaz, Ali; Kanbur, Yasin; Abaci, Ufuk; Guney, H. Yuksel (Wiley, 2012)Copolymers of poly(acrylonitrile-co-ethyl methacrylate), P(AN-EMA), with three different EMA content and parent homopolymers were synthesized by emulsion polymerization. The chemical composition of copolymers were identified ... -
Synthesis and Characterization of 2-Hydroxyethyl Methacrylate (HEMA) and Methyl Methacrylate (MMA) Copolymer Used as Biomaterial
Vargun, Elif; Sankir, Mehmet; Aran, Bengi; Sankir, Nurdan D.; Usanmaz, Ali (Taylor & Francis Inc, 2010)A series of poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA), copolymers were synthesized by an emulsion polymerization technique. Copolymer compositions were determined by FT-IR and 1H-NMR spectroscopy. ... -
Synthesis and surface properties of polydimethylsiloxane-based block copolymers: poly[dimethylsiloxane-block- (ethyl methacrylate)] and poly[dimethylsiloxane-block-(hydroxyethyl methacrylate)]
Vargun, Elif; Usanmaz, Ali (Wiley-Blackwell, 2010)A polydimethylsiloxane (PDMS) macroazoinitiator was synthesized from bis(hydroxyalkyl)-terminated PDMS and 4,4'-azobis-4- cyanopentanoic acid by a condensation reaction. The bifunctional macroinitiator was used for the ... -
THERMAL DEGRADATION OF ORIENTAL BEECH WOOD IMPREGNATED WITH DIFFERENT INORGANIC SALTS
Vargun, Elif; Baysal, Ergün; Turkoglu, Turkay; Yuksel, Mehmet; Toker, Hilmi (Univ Bio-Bio, 2019)This study investigated the thermal properties of Oriental beech (Fagus orientalis) treated with (NH4)(2) H-PO4, K-2 HPO4, NH4Cl and (NH4)(2)SO4 salts and their mixtures (1:1; w/w) aqueous solutions at 3% concentrations. ...
