    <p>Desiccant humidity control systems have been garnering considerable attention in the attempt to achieve highly efficient utilization of low-temperature heat exhausted from various industries at temperatures less than 373 K. We have focused on thermosensitive polymers as new desiccants because a large amount of dehumidified water would be expected in the system because of their thermosensitivity. Our previous study focused on the water adsorption behavior of poly(N-isopropylacrylamide) (poly(NIPA)), which has a low critical solution temperature (LCST) of 306 K. In this study, poly(N-isopropylmethacrylamide) (poly(NIPMA)) and poly(2-(dimethylamino)ethyl methacrylate) (poly(DMAEMA)) cross-linked with N,N′-methylenebisacrylamide (MBAA) were investigated. These polymers are known to exhibit thermosensitivity in the temperature range of 313–319 K in water, which is a higher LCST than that of poly(NIPA). Poly(NIPMA) adsorbed water vapor linearly with increasing relative humidity. It was also observed that poly(NIPMA) prepared at MBAA concentrations of 200 mol/m<sup>3</sup> exhibited a thermosensitivity in the temperature range of 303–313 K in water vapor adsorption. Meanwhile, poly(DMAEMA) adsorbed little water vapor up to a relative humidity (RH) of 40%; however, it exponentially adsorbed water at RH levels higher than 40%. From the estimation results of effective water adsorptivity, we found that poly(DMAEMA) is applicable in desiccant humidity control systems when the dehumidification process is performed at high RH.</p>

    <p>The Mahalanobis-Taguchi system (MTS) is one of the multi-variate analyses which can classify data by correlations among multi-variables. The MTS has significant advantage of applying a cause analysis which provides effective variable combinations to upgrade the accuracy of the classification. In this study, droppings, which were extruded from Japanese rhinoceros beetle larva were selected to classify into male/female based on their shape-related features using the MTS. Based on the cause analysis, the projected area/Feret’s diameter (A/F) and solidity were the best variable combination which all the larval droppings were classified into male/female. Both the variable has surface roughness-related factors with size effect (A/F) without size effect (solidity). The MTS has the great ability to classify from the powders’ minor difference and will be an effective tool for particle design in the near future.</p>

  11. Effects of Additional Mullite Micro-Powder on Rheological Behavior of Highly Concentrated Aqueous Silicon Slurry

    <p>Low-thermal-conductive reaction-bonded silicon nitride (RBSN), with a thermal conductivity of 8.08 W/(m·K), was developed by the addition of mullite micro-powder as a rare-earth-free oxide sintering agent to silicon nitride. This addition was expected to generate a glassy grain boundary as well as a solid solution of oxygen across the microstructure of the RBSN, which leads to low thermal conductivity. During the fabrication of a heat-insulating component with a hollow structure made of the RBSN via slip casting and subsequent reaction sintering, it was found that the viscosity of aqueous silicon-mullite slurries decreased evidently by the addition of the mullite micro-powder with ammonium polycarboxylate as a dispersant. The viscosity decreased even though the pH (7–8) of the slurries were maintained, and the particle size distributions did not vary significantly. At the effective mullite content when the viscosity decrease was attained, the ratio of the number of particles of mullite to silicon was approximately 1. Therefore, the viscosity decrease in Si slurry (50 vol%) was primarily caused by the steric hindrance due to the adsorption of dispersant by the mullite particles, preventing the direct contact among the silicon particles, rather than by electrostatic repulsions among the silicon particles. This was also explained through the modality of bimodal dispersion. Thus, it was found that the mullite not only acts as a sintering agent but also facilitates viscosity decrease of highly concentrated aqueous Si slurry, which successfully enables the integration of the slip casting and reaction sintering processes.</p>

    <p>It is meaningful to predict and design the efficiency of large-scale circulation systems in advance. However, since various energies and substances are input and discharged into the system in different qualities and shapes, it cannot be said that an index or method for evaluating the efficiency has been established. We are focusing on exergy as an index showing the common resource properties of substances and energy, and are developing an exergy graph tool (tentative name) that can be applied especially to the design of large-scale circulation systems. This time, we verified the effectiveness of the graph tool for ceramic processes using waste silicon.</p>

    <p>Influence of both surface roughness and surface morphology on frictional behavior of ceramics during run-in period under dry sliding was investigated simultaneously. Similar average surface roughness (R<sub>a</sub> = 0.01–0.02 µm) was produced for the three ceramics: monolithic boron carbide ceramics, boron carbide-silicon carbide composite ceramics and monolithic silicon carbide ceramics. Surface roughness parameters show some influence on friction processes, however, surface morphology is considered as a more important competitive factor. Lower friction coefficient during run-in period and shorter sliding distance up to the steady state condition were observed for the B<sub>4</sub>C–SiC composite ceramics, which has a different surface morphology from those of monolithic B<sub>4</sub>C ceramics and monolithic SiC ceramics.</p>

    <p>In the modern society, the promotion of energy saving while reducing the amount of waste is an important issue for modern humanity. There are two points in recycling of material. The first is the reduction of input exergy in the circulation system and the balance between cost and raw material supply between waste and recycled products. On the other hand, with the spread of electric vehicles, heat insulation technology for automobile interior parts has attracted attention. Conventionally, a composite of polypropylene using an inorganic filler has been used as an interior heat insulating material. In this study, we examined substitution of shredded paper to inorganic filler. We aim at exergy analysis of the use of fibrous paper, polypropylene and blends for thermal insulation and the effectiveness of their recycling. The surface of the composite of paper fiber and polypropylene was analyzed using a scanning electron microscope (SEM). We also calculate exergy analysis, which I would like to show in the presentation.</p>

    <p>The fracture mechanism and reliability of typical dense ceramics can be statistically analyzed using a Weibull distribution as a basis for device design. However, it is not understood if the Weibull distribution can even be applied to highly porous ceramics. In this study, porous Siliconized Silicon Carbide (Si–SiC) ceramics with anisotropic three-dimensional network structures in a porosity range of 71–92% were fabricated and subjected to a fracture analysis using the results of three-point bending tests. Observations of fracture behavior during the bending tests were conducted using a high-speed camera, image analysis of stress distribution, and observation of crack distribution inside the partially damaged specimens using X-ray computed tomography. The results indicate non-linear behavior with multiple peaks in the load–displacement curves. In this regard, the fracture mechanism of the porous Si–SiC ceramics was intrinsically different from the brittle fracture of dense ceramics and did not appear to be based on the weakest-link model. However, the Weibull distribution was found to be applicable to the bending strength of the porous ceramics with a confidence coefficient of 0.90. This was because although strain and cracks were generated sporadically during loading, the catastrophic fracture of the porous Si–SiC ceramic specimens occurred with a macroscopic crack opening at the bottom of the test specimens, almost the same as a Mode I crack opening in dense ceramics. Furthermore, graded three-layer structures can be formed integrally using the proposed novel replication method with uniaxial pressing, taking the plateau of the stress–strain curve of the template polyurethane foam into account, providing a kind of damage tolerance owing to the sporadic generation and sequential propagation of cracks, manifested as the multiple peaks shown in the load–displacement curves.</p>

Currently, as heat storage body, Al<sub>2</sub>O<sub>3</sub> ball has been used, however, for further compactification of the system, the development of new heat storage body with higher heat input rate and energy density have been required. In this study, a hollow tetrapod structure was devised as a modified shell structure made of fine ceramics. This structure aims to increase the heat transfer area by using the outside and inside surfaces of the heat storage body and to reduce the weight of the heat storage tank. The hollow tetrapod structure was made by slip cast molding method. It was experimentally considered that he heat storage rate for a short time of the packed bed of hollow Al<sub>2</sub>O<sub>3</sub> tetrapod was increased in compared with the case of conventional Al<sub>2</sub>O<sub>3</sub> body.</p>

    <p>Regenerative burner system generally ignites a pair of burners integrated with the heat reservoirs alternately at intervals of several tens of seconds. While one burner is burning, the exhaust gas passes through and heats the other burner’s heat reservoir to recover the energy of the exhaust gas. Then, when the other burner burns, the air for combustion in turn passes through the preheated heat reservoir to recover the exhaust gas energy which had conventionally been wasted, to provide high efficient combustion. In recent years, and energy saving of further industrial furnace is required, we are towards the efficiency improvement and downsizing of this regenerative burner system, it was decided to proceed with the research and development that focuses on the wall structure of the heat storage body using fine ceramics.</p>

    <p>Authors have been developing a spherical container having an inner wall constructed with skeletal ceramic units for transporting molten aluminum. This container is expected to provide innovative weight reduction and higher heat retaining property compared with current cylindrical containers having an inner wall made of castable refractory. In this study, a spherical inner wall with a combinative structure was designed: molten contacting part of the inner wall was constructed with skeletal unit made of reaction bonded silicon nitride (RBSN), while the non-contacting part with molten was constructed with skeletal unit made of aluminum titanate (AT). The quantity of heat emission from the container, temperature drop of molten in the container and thermal stress at the inner wall, while holding the molten, were simulated by heat transfer analysis. As a result, the spherical container reduced the quantity of heat emission compared with an inner wall constructed with only the RBSN unit, and was more reliable compared with that with only the AT unit. Thus, the new inner wall which enables a combination of light weight, high heat retaining property and reliability was proposed.</p>
