Organic small material lead phthalocyanine (PbPc) nanocolumns were prepared via glancing angle deposition (GLAD) on indium tin oxide (ITO) coated glass substrates. Organic electron acceptor materials fullerene (C60) was evaporated onto the nanocolumn PbPc thin films to prepare heterojunction structure ITO/PbPc/C60/Bph…
To improve the behaviors of DC-DC converters,a hysteresis control strategy with inductor current feedback is put forward. The output voltage, output of hysteresis comparator and inductor current are measured to control the capacitor voltage, the value of the capacitor voltage and the hysteresis band width are calculat…
The behavior of carbon steel SAE 1045 in 1 M NaOH solution containing different concentrations of palm kernel oil (PKO) has been studied by weight loss and polarization measurement. Results showed that the corrosion of carbon steel in NaOH solution was considerably reduced in presence of such inhibitors. The inhibitio…

The PFBR core, which is highly enriched, is very compact due to neutronic considerations. The gap provided for coolant flow is so less that deformation of the clad will disturb the coolable geometry, which may lead to severe damage to the core. If adjacent pins balloon at the same axial level (coherent ballooning) the…
福島第一原子力発電所の事故により、広範囲に拡散した大量の放射性物質を適切に除染するとともに、汚染された災害廃棄物を適切に処理、処分することが求められている。そこで本研究では、モルタル中でのセシウムの吸着、浸透、溶出挙動を把握することを目的とした。実験結果から、セメントや各種細骨材にセシウムは吸着しにくく、飽水処理したモルタル供試体では、供試体表面および内部ともに80％ものセシウムは可溶性として存在していた。一方で乾燥させた供試体の表面付近では60％のセシウムが非可溶性であり炭酸化の影響が示唆された。
The effect of intercalation of Bi atoms and the joint intercalation of atoms of Bi and noble metals (Au, Cu) on the spin and electron structure of graphene formed on Ni(111) is investigated by angle and spin-resolved PES. It is shown that the spin-orbit splitting of π states of graphene of 20–30 meV is observed for th…
TEPCO announced that the safety relief valves of the Fukushima Daiichi NPP Unit 1 were never manually opened during the accident due to the shortage of DC power. However, the measured reactor pressure was about 1MPa at 2:43 of March 12. At that moment the core damage must already start due to almost no core injection…
This study describes the application of intelligent control systems in electrospinning engineering as well as to use these approaches for optimizing processing conditions. A multi-objective optimization method based on gene algorithm (GA) has been proposed for the design and control of electrospinning process. The pro…
Solution viscosity can be regarded as the most important factor in determining the morphology of the product obtained in electrospinning. Viscosity can be adjusted for a given solution by tuning the solution temperature or by adding fillers to the solution prepared. The electrospinning of PLA solution was performed at…

Hydroxyapapite has been widely used because of its excellent biocompatibility. In this work, we studied the decomposition characteristics of both nano-hydroxyapapite powders prepared by the precipitation method and the corresponding sinters at the temperature from room temperature to 1500 C. X-Ray diffractometer, Rama…
The study presents a realised concept of an ultrasonic transducer intended to work in a gaseous medium, that radiates a focused ultrasonic beam in many directions simultaneously. The use of a L-L type vibration direction converter makes it possible to radiate ultrasonic energy in a required direction without changing…
Urea-SCR technology is the main means for heavy-duty diesel engines to meet the emission standards of CN IV and CN V 1,2 , using 32.5 % urea solution, matching with the optimal combustion, so that it can reduce the emission of NOx and effectively decrease the fuel consumption. With increasingly stringent emission regu…
Three kinds of polystyrene spheres with different sizes were fabricated on glasses by drifting method of nanosphere lithography. Au thin films with various thicknesses were prepared by magnetron sputtering under controlled deposition time. Triangle-shaped Au nanoparticles array in three different heights after removin…
Coherent x-ray micro-diffraction and local mechanical loading can be combined to investigate the mechanical deformation in crystalline nanostructures. Here we present measurements of plastic deformation in a copper crystal of sub-micron size obtained by loading the sample with an Atomic Force Microscopy tip. The appea…
Y 0.9 Gd 0.1 Fe 2 (H z D 1-z ) 4.2 compounds crystallize in a monoclinic structure at room temperature, with an increase of the cell parameters versus the H content. These compounds undergo a ferro-antiferromagnetic first-order transition, the transition temperature of which increases from 98 to 144 K for z going from…
Given a finite set $\{S_1\dots,S_k \}$ of substitution maps acting on a certain finite number (up to translations) of tiles in $\mathbb{R}^d$, we consider the multi-substitution tiling space associated to each sequence $\bar a\in \{1,\ldots,k\}^{\mathbb{N}}$. The action by translations on such spaces gives rise to uni…
Culex quinquefasciatus cause severe biting nuisance and responsible for the spread of dreadful diseases among human beings. Biological researchers are trying to introduce eco-friendly products for the control of mosquitoes. The use of botanical pesticides has become very popular throughout the world as an alternative…
