In order to combat global warming CO_2 emission reduction from the iron and steel making industry is necessary. The Active Carbon Recycling Energy System for the iron making process (iACRES) has been developed as a technical option for substantial CO_2 reduction. Lithium ortho-silicate (Li_4SiO_4, LS), which can separ…
Ammonia is a hydrogen storage material that may solve several problems related to hydrogen transportation and storage in the hydrogen economy. Catalytic thermal decomposition is a promising technique for producing hydrogen from hydrogen, however treatment of unreacted ammonia is a critical issue for fuel cell use. We…
Soldering is essential technique for assembly of parts of cars, devices, IC's, and so on. The main component of solder is tin. We electrochemically analyzed the oxidation rate of tin because that the oxide thickness affects the strength of oxide film on tin surface. The methods we used are measuring polarization curve…
A modeling methodology of polycrystalline aggregate has been studied to define the representative volume element (RVE) within finite element analyses of a periodic microstructure which enable us to estimate the deformation state of the microstructure and the corresponding macroscopic material response. In general, a p…
Improving the corrosion resistance of a thin aluminum film by surface treatment using 1, 2-Bis(triethoxysilyl)ethane(BTSE), Bis(triethoxysilyl)propyl)tetrasulfide(BTSPS), and Bis(trimethoxysilylpropyl)amine(BTSPA)was evaluated. A thin silane coupling layer of BTSE or BTSPS was formed on the film by immersion in a BTSE…
The KA facility in Rokkasho Reprocessing Plant started the active tests to solidify HAW into the glass in 2007 which was the examination of the final stage before the operation, but the active test had to be discontinued due to the trouble of glass melter operation with down of pouring by deposit of noble metals on th…
A pulse jet generator equipped with flow-control has been developed for the formation of high speed, high frequency consecutive droplets up to 140m/s, 500k drops/s for 10MPa plunger pump. The high speed pulse water jet with abrasive using this generator have been studied for surface machining to gain a smooth, reflect…
cBN-particle-dispersed-aluminum (Al) matrix composites were fabricated in solid-liquid co-existent state by Spark Plasma Sintering (SPS) process from the mixture of cBN powders, Al powders and Al-5 mass%Si powders. The microstructures and thermal conductivities of the composites fabricated were examined. These composi…
This paper presents a direct numerical simulation of a flexible filament in a flowing soap film and a small-scale von Karman vortex street trailing behind the filament. The numerical method is an interface-tracking ALE finite element method with an implicit and monolithic time integration scheme. The numerical results…
Recently, flight characteristic of dragonfly has been investigated by many researchers. In particular, wing motion such as dragonfly has attracted attention. Dragonfly has high flight performances in spite of small size. On the other hand, dragonfly wing has about 3000 of micro spikes of which length is about from 10…
Surface design is important when designing micro/nano-scale devices as their function and performance are largely determined by the surface properties of adhesion, friction, wear, and wettability, etc. For the purpose of surface design, we have developed a method to pattern molecularly thin liquid lubricant films coat…
This paper deals with the basic cutting characteristics of tungsten carbide using a diamond-coated carbide end mill at ultrasmall feed rates. The influence of cutting conditions on the cutting force and tool life were experimentally investigated. The three components of the cutting force were decreased by occurrence o…
In recent years, the price of alloys, such as Ni and Mo rises, so that it is difficult to use the stainless steel containing these elements. Therefore, Ni was reduced and Mn and N were added to the conventional stainless steels alternatively. 'Lean grade or Low grade1 duplex stainless steels have attracted industrial…
A numerical approach of structural analysis is proposed for carbon-fiber reinforced plastics (CFRP) by combining atomistic simulation and finite element analysis using Materials Studio and Abaqus. Heat curing resin is modeled by molecular dynamics (MD) with consideration of cross-linking reaction, and thermal and mech…
The purpose of this study is to investigate the mechanical properties of wood plastic composites (WPC). The target of this study was the wood particles of 1-100 um which were fabricated by wet milling. In this paper, the mechanical properties of WPC were evaluated by the tensile test. Wood flour obtained from thinning…
Dynamic behavior of unburnt diesel sprays under no-evaporation and evaporation conditions were investigated by dual nano-spark shadowgraph photography method. This method enables obtaining two individual high definition shadowgraph images with short photographing interval. Details of temporal behavior can be obtained…
Wood is a complex material which has late part on a hard layer and early part on a soft layer. In order to expand an application of wood, the mechanical properties of wood should be investigated. In this study, the indentation test to the micro region of wood is carried out. The mechanical properties of wood can be gi…
A new method for producing gapless biaxial microlens array is proposed for a dual-directional light-control film with a high fill factor. Three steps in this production technique are included for formations of semiellipsoid microlens array with low fill factor to be caulked into gapless biaxial microlens array mold in…
When grain size decreases to the nanometer scale, dislocation structures hardly form in the grain; hence, it cannot be expected to obtain a large work hardening rate for nanostructured materials within the conventional framework of the theory based on the dislocation-dislocation interaction. However, the strength cont…
Since titanium has a corrosion resistance and biological compatibility, it has recently been used in aeronautics and biomedical fields such as the development of artificial bone, medical tools and equipment. These specific applications often require a mirror-like surface in order to achieve an optimum efficiency and q…
