Thirty-two molecules were designed as donor–bridge–acceptor (D–π–A) push-pull type nonlinear optical (NLO) chromophores with five-membered heterocyclic (O, S, NH, PH) bridges. An eigenvector following (EF) method was employed to optimize the structures of the molecules and a parametric method number six (PM6) method w…
Sporocytophaga sp. JL-01 is a sliding cellulose degrading bacterium that can decompose filter paper (FP), carboxymethyl cellulose (CMC) and cellulose CF11. In this paper, the morphological characteristics of S. sp. JL-01 growing in FP liquid medium was studied by Scanning Electron Microscope (SEM), and one of the FPas…
Deuterium retention after low energy plasma exposure was investigated using the polycrystalline tungsten samples of which grain elongation directions are parallel and perpendicular with respect to the surface. The deuterium retention calculated from TDS spectra is 2-10 times larger in the sample with perpendicular gra…
We prepared mesoporous silica particles with inner surfaces coated with carbonaceous materials. A functional mesoporous silica particle (FSP) having methoxy urethane moieties tethered to the pore wall was synthesized by the template method from tetraethoxysilane (TEOS) and an amphiphilic organotriethoxysilane bearing…
We report a controllable nanoscale diffusion-limited chemical etching for detaching aligned polystyrene nanocones from 3D taper-nanopore alumina templates, which can be recycled.
The chemical state analysis of AES is, at present, performed only for some limited elements. This is because the peak broadness and the shape complexity of Auger spectra make it very difficult to identify the superimposed spectrum as each individual specific chemical state. In this report an advanced chemical state an…
Most of the studies carried out in this area have been devoted to measuring static thermal properties. Nevertheless, not only the amount of heat released to the environment is important but also the process of heat transmission over time. However, investigations in the field of the heat transfer process through knitte…
This paper examine the microstructure and the mechanical properties of maize stalk ash particles reinforced polyester composites with the aim of producing a composite material showing enhanced properties for engineering applications. Maize stalk ash particles (MSAp) were added in different volume fractions into a poly…
Owing to the unique order mesopores, mesoporous SBA‐15 could be used as the carrier of the magnetic nanoparticles. The magnetic nanoparticles in the frame and the mesopores lead to the exchange‐coupling interaction or other interactions, which could improve the magnetic properties of SBA‐15 nanocomposites. Mesoporous…
Optically transparent and bulk single crystal of l-histidine hydrochloride monohydrate (LHHM) was successfully grown by slow evaporation technique. The cell parameters and the crystallinity of the grown crystal were estimated by the single crystal XRD. Optical transmittance of the crystal was recorded using the UV-vis…
Functional corrosion-resistant glass enamel coatings make it possible to protect inner surface of oil pipelines in extreme operating conditions. The aim of this study is to propose competitive fluorine-free coatings for energy-effective direct-on enameling technology of pipes. The enamel coatings were applied on the s…
In a study of diatoms from ten springs and fi ve streams of Turkmen Mt. we identifi ed over 300 diatom species, 59 of which are among the most commonly reported diatoms from Turkey. Several of these diatoms are truly widespread but can also be accompanied or replaced by taxa of more limited distribution. Some commonly…
Since the technology concerning gamma radiation showed a rapid development, it became a necessity to be protected from it. One of the common shielding materials for this purpose is concrete. This study aims to give the effect of pumice rate on the gamma radiation attenuation coefficients of normal concrete ( = 2.476 g…
The effect of impurity elements on the mechanical properties of Ti-6Al-4V alloy is presented in this paper. Impurity levels of oxygen and iron were varied between 0.1 and 0.7%. Tensile and proof strength increased and elongation, cross-sectional area reduction, and Charpy impact strength decreased as the oxygen conten…
In2O3/C core-shell nanospheres have been synthesized via template-free hydrothermal approach at 200 °C first, then treated in glucose aqueous solution and annealed at 500 °C. The products were around 100 nm in dimension with carbon shell about 10 nm in thickness. Electrochemical tests demonstrated that the In2O3/C cor…
The study describes recent simulation results for underwater explosions in close-proximity to rigid targets. Simulations are performed using Chinook, an Eulerian computational fluid dynamics (CFD) code. Predicted target loadings are compared with measurements taken from a series of experiments conducted under an inter…
Objective: To evaluate the impact of the fortification of rolls with microencapsulated iron sulfate with sodium alginate on the hemoglobin levels in preschoolers as compared to controls.Methods: Double-blind randomized controlled trial comprised of children aged 2 to 6 years with initial hemoglobin exceeding 9 g/dL fr…
In the present study, nano-structured ZrO2doped ZnO photocatalysts withhigh sunlight photocatalytic activity were successfully synthesized through theelectrochemical method. The prepared photocatalysts were characterized byPositron annihilation lifetime spectroscopy (PALS), Powder X-ray diffraction,Scanning electron m…

一系列 Mn-Cu 混合了氧化物催化剂被降水准备方法。催化剂被 N2 吸附解吸附作用， H2-TPR 和 XPS 描绘。当到铜氧化物的锰氧化物的装载比率是 8:2 或 7:3 时，催化剂拥有了更好催化的活动，并且苯在 558 K 完全被变换。H2-TPR 的结果证明装载铜氧化物的小数量减少了催化剂的减小温度。XPS 的结果证明装载铜氧化物的小数量在催化剂的表面上增加了锰和有缺点的氧的比例，并且以更高的氧化状态稳定了锰。并且自从在锰氧化物和铜氧化物之间的相互作用是太强壮的，有装载比率 7:3 的催化剂比 8:2 有点更坏，铜氧化物在过量移居到催化剂和锰氧化物的表面被埋头。
