(Summary) <p>The major objective of the present study was to investigate the creep fracture process of a copper tricrystal having 110 -tilt Σ3, 3, 9 grain boundaries. Creep tests at 0.81 T<sub>M</sub> (T<sub>M</sub>: melting temperature on the absolute temperature scale) under 4 MPa tensile stress were carried out for three samples prepared from the same tricrystal. Grain-boundary sliding occurred along only the Σ9 boundary, and the triple junction of the boundaries completely suppressed the sliding. The three samples were in different stages of creep deformation. Creep fracture was initiated by sliding-induced voids along the Σ9 boundary. Grain-boundary damage by the void formation developed into complete separation along the Σ9 boundary, and the Σ9 boundary crack induced surface grooves along one of the Σ3 boundaries, arranged almost perpendicular to the tensile axis. The crack propagation resulted in the final fracture of the tricrystal along the Σ9 and Σ3 boundaries. The formation of cavities in the Σ3 fracture surface suggested that the final fracture occurred in a ductile manner after the neighboring grains were partly separated along the Σ3 boundary.</p> (Keyword) tricrystal / copper / creep fracture / grain-boundary sliding / void / crack (Link to Publication Site) ● Publication site (DOI): 10.2320/matertrans.MT-M2022066 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390855809731163264 ● Search Scopus @ Elsevier (DOI): 10.2320/matertrans.MT-M2022066 (DOI: 10.2320/matertrans.MT-M2022066, CiNii: 1390855809731163264)

(Summary) In the transformation reaction of alkanes to alkenes via catalytic dehydrogenation, it is generally accepted that the so-called catalytic deactivation behavior will occur. This phenomenon causes a drastic reduction in activity with time-on-stream. It is understood that carbon deposition generated during the reaction then covers the surface of the catalyst, and this leads to a drastic decrease in activity. However, contrary to this common wisdom, our laboratory reported that the dehydrogenation of isobutane to isobutene on NiO/γ-Al2O3 within a specific range of NiO loading in the presence of CO2 actually improved the yield of isobutene with time-on-stream. Since few such cases have been reported, in this study, isobutane was dehydrogenated in the presence of CO2 using NiO/α-Al2O3 as the catalyst with 20% NiO loading and improvement was again observed. In order to investigate the cause of the improvement, both NiO/γ-Al2O3 and NiO/α-Al2O3 with 20% NiO loading were examined in detail following the reaction. According to TEM analysis, both catalysts were covered with a large amount of carbon deposition after the reaction, but there was a difference in the types. The carbon deposition on NiO/γ-Al2O3 had a fibrous nature while that on NiO/α-Al2O3 appeared to be a type of nanowire. Raman spectroscopy revealed that the carbonaceous crystal growth properties of two forms differed depending on the support. In particular, a catalytically active species of metallic nickel was formed in a high degree of dispersion in and on the above two forms of carbon deposition during the reaction, and this resulted in high activity even if the catalyst was covered with a carbon deposition.

Waterhouse and Yan Li : Influence of alkali treatment on internal microstructure and tensile properties of abaca fibers, Industrial Crops and Products, Vol.65, 27-35, 2015. (Summary) The objective of this study is to investigate the effect of alkali treatment on the internal microstructure and tensile properties of abaca fibers. The abaca fibers were immersed in aqueous solutions of NaOH (5, 10, or 15 wt%) for 30 min, rinsed and dried. The fibers were subsequently characterized by scanning electron microscopy, X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), and tensile strength tests. The lumen is a hollow region in each elementary fiber of the abaca fiber bundles. It was found that the lumen of the abaca fibers completely collapsed after 10 and 15 wt% NaOH treatment, due to swelling of the fibers. The fibers also became twisted after these alkali treatments. It was found that cellulose I in abaca fibers was partially transformed to cellulose II after 15 wt% NaOH treatment, as evidenced by XRD measurements. FT-IR analysis indicated that the alkali treatment led to a gradual removal of binding materials; such as hemicelluloses and lignin, from the abaca fibers, resulting in the separation of abaca fiber bundles into individual elementary fibers. The tensile strength of alkali-treated abaca fibers did not vary with alkali concentration. The Young's modulus of the abaca fibers treated with 5 wt% NaOH solution increased by 41%, whereas those treated with 10 and 15 wt% NaOH solution decreased by 24 and 29%, respectively. A non-linear behavior was observed in the stress strain curves of the abaca fibers after 10 and 15 wt% alkali treatment, which could be attributable to the twisting of the fibers.

In the present copper single crystal sample, both right-up and right-down band-like regions are formed in which either of the primary slips was activated. The arrangement of band-like regions on the overall sample surface was almost symmetrical. Between band-like regions, there were regions of patchy slip appearance, consisting of double-slip and single-slip areas. The band-like regions were rotated so that the slip directions moved towards the tensile axis.

(Summary) Platinum nanoelectrodes, which the electroactive region is located on the tip, were prepared in two steps. First, an insulating film was formed on the tapered tungsten probe by electrodeposition coating using the cationic electrodeposition paint, and then platinum nanopillars with a diameter of about 200 nm were formed on the tip using Focused-Ion-Beam Chemical-Vapor-Deposition (FIB-CVD). The conditions for forming an insulating film on tungsten surface with low thickness and excellent insulation properties were investigated and were evaluated by electrochemical measurements and SEM observations, and an appropriate insulating film was successfully produced. After the formation of a platinum pillar on the tip of an insulating film-coated tungsten probe, a platinum nanoelectrode was obtained and confirmed to function as an electrode. Using automatic micro manipulation system, repeated insertion of platinum nanoelectrode into HeLa cell was attempted. The results showed that the insertion of platinum nanoelectrodes into HeLa cells appeared to be successful.
