The finished and preformed forgings of the rear lower arm are shown respectively, the shape of the rear lower arm is very complex.The tops of three branch arms are thick lumps and its central part consits of quite thin ribs.This forging is much more slender than the ordinary weldment made of steel plate and its weight…
Short-cut grass and starch were selected as raw materials to prepare environmentally friendly composite by hot-pressing method. Results indicated that short-cut grass and starch were easily mixed uniformly by water medium and adapt to hot-pressing process. Hot-pressing time and hot-pressing temperature influenced the…
A Ce-Zr-Ti oxide catalyst was prepared by an impregnation method and tested for the selective catalytic reduction of NO with NH3. The Ce-Zr-Ti oxide catalyst exhibited high activity and more than 95% NO conversion was obtained within the temperature range 300-500 °C at the high gas hourly space velocity of 50,000 h-1.…
The effect of carbon ion species distribution in arc discharge process becomes significant for the formation of carbon nanomaterial. It is essential to account for the velocity distribution of each carbon ion species to determine the greatest contribution from the kinetic energy possesses by each species that govern t…
This special Energy Materials issue of Materials Research Innovations includes four selected papers from those presented at the 2013 PVSAT Conference held in Swansea on 10–12 April. PVSAT is an ann...
Capping CdS nanorods on one side with Au nanoparticles makes these asymmetric nano-objects amphiphilic. As D. Mandler and co-workers report in article 1300030, this enables the formation of 2D nanometric monolayers at the liquid/air interface using the LB technique. This interesting system is studied in situ by variou…
Nanometer-sized gold particles supported on Cerium Oxide (CeO2) were prepared by the method of deposition-precipitation. These catalysts exhibited good activity for the combustion of formaldehyde and the factors affected the activity of the catalyst were observed. The results showed that CeO2 powder prepared by Ce (NO…
This paper presents a review of researches of luminescent optical glasses and fibers containing silver molecular clusters and semiconductor quantum dots. These materials can be applied for spectral radiation conversion in photonic devices, including fiber optic sensors of electrical discharge and temperature, luminesc…
Differentiation in microstructural characteristics ofPunica granatumfruit in response to different dynamic temperatures (2 oC, 4 oC, 6 oC, and 8 oC) during cold storage inside the fibre insulation materials was investigated. The results from Fourier Transform Infrared Spectroscopy (FTIR) measurements showed that the p…
All future engine developments must consider the primary task of achieving the required emission levels. An important step towards the development of combustion engines is the optimization of the flow in the intake ports. The charging movement in the combustion chamber, which is generated by the intake flow, considera…
Today various nano-moieties including nanoparticles, nanocubes, nanosticks, nanoflowers and nanoprimes have been synthesised. It is an interesting challenge to build nanostructures using those nano-moieties as blocks owing to their distinct properties and numerous applications. Herein, we demonstrate a smart way, self…
The diffusible rejuvenator containing dissolving-diffusing agent was prepared. Effects of the diffusible rejuvenator on properties of recycled asphalt mixture were investigated in comparison with those of common rejuvenator. The results show that the properties of recycled asphalt mixture were significantly improved w…
The theoretical optimization of the process was based on our kinetic model of MCH dehydroalkylation with methanol in the presence of HNa TsVM zeolite (SiO 2 /Al 2 O 3 =30) modified with platinum and gallium and gadolinium oxides.
The diesel methanol combinational combustion (DMCC) engine with methanol fumigation has been shown considerable petroleum-saving potential and obvious fuel cost reduction. However, the DMCC engine emissions have been deteriorated severely. The selective catalyst reduction (SCR) schemes therefore were investigated to f…
Microelectrodes are a powerful tool for interfacing neural tissue with electronics, both for in vitro and in vivo. So called microelectrode arrays allow for electrical recordings as well as for electrical stimulations at many parallel sites. Their design and substrate may vary strongly with the field of application. F…
중앙에 균열을 갖는 단층 그래핀시트(single layer graphene sheet, SLGS)의 모드 II 파괴 거동을 원자시뮬레이션과 해석 모델에 기초하여 고찰하였다. 지그재그 그래핀 모델의 파괴를 분자동역학(molecular dynamics, MD)에 의해 해석한 결과 모드 II 파괴인성은 2.04MPa√m인 것으로 밝혀졌다. 또한 SLGS 의 이론적인 KIIc 를 유도하기 위해 면내전단하중을 받는 다공체에 대한 파괴역학적 해석도 진행하였고 유한요소해석도 병행하였다. 모드 I 과 모드 II 의 비를 다양하게 변화시켜가면서 SLGS 의 혼합모드 파괴를 검토한…
In article number 1300632, Jong Hak Kim and co-workers present a nanopatterning technique using nanostamps that provides a facile process to create a nature-inspired moth-eye structure. The structure achieves high transmittance in the visible range as well as a self-cleaning effect. The resulting solid-state dye-sensi…
Liquid-crystal-based films of different thicknesses, fabricated by the Langmuir technology, have been studied. Previously, we revealed a structural phase transition in these films at a temperature of ∼75°C. To clarify the nature of this transition, the temperature dependences of the capacitance and conductance of thes…
A Ni-7.2at%Ti alloy was prepared and thed-electron occupancy of Ni was measured from electron energy loss spectroscopy (EELS) of nickel. The results showed that the white-line intensity of Ni EELS and thed-electron occupancy of Ni in Ni-7.2at%Ti alloy did not change significantly relative to pure Ni.
