Abstract We improved organic light-emitting transistors (OLETs) characterized by aluminum-doped zinc oxide (AZO) layer insertion between organic and gate insulator layers using organic oligomer semiconductor crystals. (i) To ensure firm contact between the crystal and the AZO layer, we shaped the AZO layer into a rect…
Silica supported polyoxometalate K 4 [a-SiW 12 O 40 ]·nH 2 O was prepared systematically using tetraethyl ortho silicate by sol gel method to form K 4 [a-SiW 12 O 40 ]·nH 2 O/Si. Compound K 4 [a-SiW 12 O 40 ]·nH 2 O/Si was characterized by diffraction, spectroscopic, and acidity analyses follow by thermal activity tes…

Due to the paraantiferromagnetic transition of oxygen at 45 K, the contamination with this element may deeply affect measurements performed with high-resolution magnetometers around this temperature. We have studied this spurious effect by measuring with a commercial SQUID-based magnetometer (Quantum Design, model MPM…
This special topical volume on is aimed to cover the recent advancements and trends in the area of building materials with reference to energy efficiency and sustainable development. The volume will be of special interest to environmentally-minded producers of building materials and to engineers, architects and buildi…
A new technique to quantify signal-to-noise ratio (SNR) value of the scanning electron microscope (SEM) images is proposed. This technique is known as autocorrelation Levinson-Durbin recursion (ACLDR) model. To test the performance of this technique, the SEM image is corrupted with noise. The autocorrelation function…
Adv. Energy Mater. 2015, 5, 1500665 On page 3 of the originally published article, there is a production error in Figure 2b. The X-ray photoelectron (XPS) spectrum for graphene oxide (GO) was omitted from the published version in error. The full figure with the missing spectrum included is shown here. The editorial of…
We demonstrate a simple, scalable fabrication method for producing large-area arrays of vertically stacked metallic micro-rings, embedded in a deformable polymer sheet. Unusual polarisation-dependent hotspots are found to dominate the reflection images. To understand their origin, the arrays are characterized using po…
In this study, novel ferrocene-functionalized N-alkyl substituted pyrrole derivatives, namely 4-ferrocenyl-1-[3-(pyrrol-1-yl)propyl]-1H-1,2,3-triazole (Py3Fc), 4-ferrocenyl-1-[4-(pyrrol-1-yl)butyl]-1H-1,2,3-triazole (Py4Fc), and 4-ferrocenyl-1-[6-(pyrrol-1-yl)hexyl]-1H-1,2,3-triazole (Py6Fc), were synthesized via clic…
This paper addresses a simple method to prepare antibacterial carboxymethyl cellulose (CMC)/polyoxyethylene(PEO) nanofiber mats containing silver nanoparticles (Ag NPs). The nanofibers are fabricated by electrospinning of CMC/PEO/AgNO3 blend aqueous solution with an AgNO3 concentration of 10mmol/L. In electrospinning…
Abstract The utilization of CaSO 4 -based oxygen carrier suffers the deactivation problem caused by sulphur loss. To capture the gas sulphides and to improve the stability of CaSO 4 oxygen carrier, calcined limestone was introduced into the fuel reactor of Chemical Looping Combustion (CLC). Kinetic behaviors and therm…
Abstract The thermal behavior of 1,2,4,5-tetracyanobenzene (TCNB), the synthesis of metal-2,3,9,10,16,17,23,24-octacyanophthalocyanine–metal [MPc(CN)8–M] (M = Cu, Fe, Ni) complexes by the tetramerization of TCNB, and the growth of MPc(CN)8–M nanorods were investigated. By chemical vapor deposition (CVD) in vacuum, MPc…
Dielectric and magnetic properties in the relaxor magnet LuFeCoO4 having a triangular lattice are studied by permittivity, magnetization, and neutron diffraction measurements. We found that LuFeCoO4 has the nuclear diffuse scattering induced by Polar Nanoregions (PNRs) where local polarizations in nanoregions are rand…
In this study we measured radon (Rn) concentrations in offices at the Meselik campus of Eskisehir Osmangazi University to estimate the effective dose of Rn and its progeny for office occupants. The measurements were performed four times in 2011 over a period of 3 months using solid state nuclear track detectors (LR-11…
Tokyo Gas has developed a residential fuel cell CHP system named “ENE-FARM” jointly with Panasonic, and began to sell ENE-FARM as the world’s first commercial fuel cell cogeneration system in May 2009. Following the first-generation model of ENE-FARM, the second-generation was released in 2011, and the third-generatio…
