    In the vitrification process of alkaline waste (ALW), the viscosity and electrical conductivity of molten glass are crucial properties because ALW is immobilized by a joule-heated liquid-fed ceramic melter. This motivated us to perform the present study to evaluate the viscosity and electrical conductivity of molten borosilicate-based ALW glass with waste simulants (i.e. SiO2-B2O3-Al2O3-ZnO-MgO-P2O5-Na2O system) by varying the temperature and Na2O concentration. The temperature dependence of both properties obeys the Arrhenius equation. The measured viscosities were compared with property-compositional models, and it was revealed that the high-MgO content in the ALW glasses results in poor fit with published compositional models owing to the limitation of a dataset. Hence, the measured data in this study is beneficial for developing property-compositional models in terms of compositional variety.

    <p>Wettability between molten iron and non-metallic inclusions is an important factor, as it influences the behavior of non-metallic inclusions during secondary metallurgy. In the present study, the wettability of CaS against molten iron was investigated using the sessile drop method at 1873 K. The CaS substrate was fabricated using spark plasma sintering, achieving a high relative density of 98%. The measured contact angle of CaS against molten iron was found to be 118 degrees. This finding indicates that the wettability of CaS is poor, which contrasts with the previous report. This result will contribute to further understanding regarding the inclusions’ behavior during secondary refining processes.</p>

    <p>This study investigates the viscoelastic properties and the transition behavior between the liquid and solid of polyethylene beads dispersed in silicone oil and silicone oil-water mixtures, simulating the flow behavior of a layered structure consisting of iron ore and a coke bed with derived melts. Oscillation tests revealed that all samples exhibited elastic responses at small strains, transitioning to viscous responses at higher strains. Higher viscosity of silicone oil led to reduced strain at the onset of flow, indicating enhanced lubrication between solid phases. Creep tests showed minimal strain under low stress but significant strain increase over time at high stress, suggesting that the system can achieve a more fluid-like state over an extended period. These findings highlight the impact of liquid viscosity and phase fraction on the mechanical properties of complex multiphase systems.</p>

  • Evaluation of Analytical Uncertainty in Quantitative Determination of Elements - The Case of Boron Reviewed

    Takehiro Sumita, Takahito Osawa, I-Huan Chiu, Atsushi Ikeda-Ohno

    Analytica Chimica Acta   15 ( 1329 )   343256 - 343256   2024.9   （ ISSN:0003-2670 eISSN:1873-4324 ）

    Background: The uncertainty including accuracy and precision is the most vital factor that determines the overall quality of quantitative analysis. The uncertainty has been, however, evaluated relatively within the same analytical technique. Given this background, the present study evaluates the uncertainty on quantitative elemental analysis with a quasi-absolute approach. The objectives of this study are (1) to investigate the analytical uncertainty of prompt gamma-ray analysis (PGA), a chemical interference-free method in principle, on the quantitative analysis of boron and (2) to evaluate the applicability of inductively coupled plasma optical emission spectrometry (ICP-OES), a common technique for quantitative elemental analysis including boron. Results: PGA provided analytical quantity that is equivalent to the true quantity. The quantity values determined for a series of boron-containing samples are all well above the detection limit of the PGA system, the quantity resolution of which is also much smaller than the minimum difference in quantity among the samples. These facts confirm that the evaluation of analytical uncertainty with the present PGA system is statistically meaningful. The analytical uncertainty in both methods was adequately evaluated by comparing the results from PGA and ICP-OES for a series of boron-containing materials with different physical/chemical properties (i.e. CrB2, B4C, and solidified products of stainless steel-B4C melt) and the major sources of uncertainty in both methods are specified. The conditions for sample preparation/pretreatment were optimized to lower the uncertainty. Significance and novelty: This study proposes a new concept to perform the quasi-absolute evaluation of analytical uncertainty by employing a chemical interference-free technique. The proposed concept is not limited to the combination of PGA and ICP-OES as demonstrated in this study, but it is applicable to any combination of any analytical methods for any element. Hence, the concept demonstrated in this study could be beneficial to a wide range of analytical chemistry.

  • Comparison of the viscoelastic properties and viscosity of suspensions determined by oscillation and creep testing

    Nakanishi Kento, Sumita Takehiro, Saito Noritaka, Nakashima Kunihiko

    <p>Knowledge of the viscoelastic properties of suspensions is essential for many industrial processes. Although oscillation and creep testing are widely used to measure the viscoelastic properties of complex fluids, few studies on the correlation between the viscoelastic properties measured using these methods have been published. This study aims to provide insights into the differences between these methods and determine which method is better suited for a particular application. The room-temperature viscoelastic properties of a suspension composed of polyethylene beads dispersed in a silicone oil matrix were measured by oscillation and creep testing and compared. The results of oscillation testing indicated that the suspension showed weakly elastic deformation, whereas the results of creep testing revealed that the suspension was relatively elastic, with the liquid phase showing lower viscosity. In addition, the viscosity measured by oscillation testing was lower than that measured by creep testing. When the imposed flow causes microstructural changes, such as when the shear flow and particle‒particle contact induce aggregation, the analyzed flow property considerably differs between testing methods.</p>

    <p>Gas permeability in a blast furnace is maintained via a layered structure comprising iron ore and a coke bed. High temperatures may induce a breakdown of this layered structure, and hence, an understanding of the transition from solid-like deformation to liquid-like deformation is crucial for preventing the breakdown. In this study, the flow behavior analogous to that of a layered structure comprising iron ore and a coke bed with derived melts was examined using polyethylene beads and silicone oil. Oscillation and creep tests were conducted on analogous samples of polyethylene beads and silicone oil with viscosities similar to that of the slag melt. The samples were prepared by mixing at liquid-phase to solid-phase volume ratios of 10/90, 25/75, and 40/60. Air was present in the samples used herein. The transition between the solid-like and liquid-like flow was investigated via oscillation testing, and the flow behavior on long timescales was investigated via creep testing. The results of oscillation testing indicated that a larger strain is required for flow at an intermediate liquid fraction or greater liquid viscosity. The results of creep testing revealed that the sample deformation changes from decelerating to accelerating as the applied stress increases at higher or lower liquid-phase fractions. In contrast, at an intermediate liquid fraction, the sample deformation decelerated at a relatively higher stress. The number of liquid bridges may be the highest at an intermediate liquid fraction, and the force between the particles generated by the liquid bridges is expected to be the most significant.</p>

    Solidification and re-melting mechanisms of SUS-B4C eutectic mixture
    Fundamental understanding of the high-temperature interaction between stainless steel (SUS) and B4C is indispensable for estimating and characterizing the fuel debris generated during severe accidents of boiling water reactors (BWR), such as Fukushima Dai-ichi Nuclear Power Station (FDNPS, also referred to as "1F") in Japan. This study aims at systematically characterizing the solidified products of molten SUS-B4C mixtures by powder X-ray diffraction (PXRD), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), and thermogravimetry-differential thermal analysis (TG-DTA) with a range of the B4C content relevant to the fuel debris composition expected at 1F, in order to elucidate the solidification and re-melting mechanisms. The results indicated that gamma-Fe and (Cr,Fe)(2)B are the major solidified phases when the B4C content is below 3 mass&#37;, while (Cr,Fe)(23)(C,B)(6) is formed as an additional third phase when the B4C content exceeds 3 mass&#37;. The solidification of molten SUS-B4C mixture and remelting of solidified SUS-B4C melt are eutectic, which is mainly controlled by the pseudo-binary Fe-B system that is influenced by the C and Cr content and additional minor components such as Mo.

    Analysis of Seminar Formation Factors and Their Relevance in Science and Engineering Education based on Skopos Theory
    In this research, an analysis of seminars diversity and their characteristics based on translation studies (Skopos theory) was conducted to obtain knowledge to improve the quality of seminars in university laboratory. From the investigation that regarded expression of the seminars as intersemiotic translation, seven types of activities were found : (1) introducing papers, (2) reading materials in turn, (3) progress report, (4) presentation, (5) discussion, (6) lecture, and (7) others. With the focus on progress report, the relevance between the seminar formation factors and students&amp;rsquo; growth was considered by integrating the factors with Skopos. With the idea that the diversity was created by the factors, it was inductively concluded that by adjusting factors, enhancement of specific educational effects can be achieved.

    Dissolution behavior of core structure materials by molten corium in boiling water reactor plants during severe accidents
    For the decommissioning of the Fukushima Daiichi Nuclear Power Plant, it is necessary to consider the access route to the fuel debris for its removal, which can be determined by knowing the corruption situation of the core support structure. To predict the damage condition of reactor vessel, dissolution behavior of the core structure material should be understood. In this study, the dissolution behavior of core structure materials (stainless steel) by molten metallic corium (stainless steel + B4C) originated from control rod and its cladding was investigated. As a result of immersion experiment, it was found that there were two types of dissolution mode in this system: (1) chemical dissolution by eutectic reaction between Fe and B and (2) physical dissolution caused by the grains falling off from solid steel due to infiltration of molten metal. Moreover, on the basis of kinetic analysis, it was considered that the chemical dissolution in this system was slow. Therefore, the dissolution is considered to mainly occur through the mechanism that physical dissolution precedes chemical dissolution.

    As a consequence of severe accident in Fukushima Dai-ichi nuclear power plant, the fuel debris was formed at the bottom of reactor container due to the reaction between the dropping corium and structural stainless steel. To assess the access route to the fuel debris for its removal, corrosion condition of the structural stainless steel should be well understood. In this study, the SUS304 stainless steel and Fe-Cr-Ni-B-C alloy were employed to investigate the corrosion behavior. By immersion experiment, the diffusion coefficient of boron into the SUS304 stainless steel was estimated. The dissolution time of SUS304 stainless steel rod into the liquid alloy was predicted.

    本研究では、ホウ素材料分析の高度化を目指す。
    新材料開発を推進するうえで、材料の正確な組成情報は必要不可欠である。ところが材料の機能発現の一翼を担っているホウ素においては、その定量分析の困難さから、材料中濃度が正確に定量されていない。
    そこで本研究では、即発ガンマ線分析の強みを生かして各種汎用分析手法におけるホウ素分析確度を評価する。
    本研究から得られるホウ素分析の定量確度・精度に関する知見をまとめることで、分析手法・分析機関に依らない新材料研究に貢献する。
