Carbon Pseudocubes from Iron Oxide Templates for Capacitive Energy Storage
Sinan, Neriman; Ünür Yılmaz, Ece (Electrochemical Soc Inc, 2020)A surface-protected etching approach was used to synthesize monodisperse partially hollow carbon nanostructures with pseudocubic shapes. Monodisperse chemical templates (alpha-Fe2O3, MF) were synthesized by the gel-sol ... -
Diatom-Derived SiO2/N-Doped C Nanocomposite for Electrochemical Capacitors
Ünür Yılmaz, Ece; Yılmaz, Mete (Electrochemical Soc Inc, 2020)Microalgae present a massive and untapped natural source of biomass for various applications. The fresh-water microalgae biomass was collected from Lake Uluabat in Turkey. Diatoms, which contain large amounts of SiO(2)in ... -
Effect of vulcanization time on crosslink density and aging performance of natural rubber composites
Dayioglu, Ahu Kor; Balaban, Seda; Ünür Yılmaz, Ece (Carl Hanser Verlag, 2020)Natural rubber composites are widely used in the automotive industry because of their improved viscoelastic characteristics that are mostly governed by crosslink density. However, rubber parts suffer deterioration of ... -
Fe3O4/carbon nanocomposite: Investigation of capacitive & magnetic properties for supercapacitor applications
Sinan, Neriman; Ünür Yılmaz, Ece (Elsevier Science Sa, 2016)Fe3O4 nanoparticles with similar to 10 nm diameters were synthesized by an extremely low-cost, scalable and relatively biocompatible chemical co-precipitation method. Magnetic measurements revealed that Fe3O4 nanoparticles ... -
Functional nanoporous carbons from hydrothermally treated biomass for environmental purification
Ünür Yılmaz, Ece (Elsevier Science Bv, 2013)Hydrothermal carbonization (HTC) was utilized as a pretreatment method to convert high oxygen content lignocellulosic biomass, otherwise invaluable renewable material, to a more condensed functional material for higher ... -
Hydrothermal conversion of lignocellulosic biomass into high-value energy storage materials
Sinan, Neriman; Ünür Yılmaz, Ece (Elsevier Science Bv, 2017)Preparation of hierarchically porous, heteroatom-rich nanostructured carbons through green and scalable routes plays a key role for practical energy storage applications. In this work, naturally abundant lignocellulosic ... -
Nanoporous carbons from hydrothermally treated biomass as anode materials for lithium ion batteries
Ünür Yılmaz, Ece; Brutti, Sergio; Panero, Stefania; Scrosati, Bruno (Elsevier Science Bv, 2013)Biomass is transformed to carbon nanoparticles with surface-end groups called 'hydrochar' (HC) by an efficient and green hydrothermal carbonization (HTC) method. Three different approaches are used to introduce porosity ... -
PEDOT:PSS Enhanced Electrochemical Capacitive Performance of Graphene-Templated delta-MnO2
Sinan, Neriman; Ünür Yılmaz, Ece (Korean Electrochemistry Soc, 2020)Birnessite-type manganese dioxide (delta-MnO2) with hierarchical micro-/mesoporosity was synthesized via sacrificial graphene template approach under mild hydrothermal conditions for the first time. Graphene template was ... -
Synergistic effect of biomass-derived carbon and conducting polymer coatings on the supercapacitive energy storage performance of TiO2
Torbali, M. Ebubekir; Ünür Yılmaz, Ece (Carl Hanser Verlag, 2020)The application of anatase titanium dioxide (TiO2), which is an abundant and cost effective resource, in supercapacitors has been restricted due to its poor electronic conductivity and limited mechanical stability. A ...
