Methodology for Mapping the Residual Stress Field in Serviced Rails Using LCR Waves

Thermal barrier coatings (TBCs), as effective thermal protection separating the substrate from high-temperature combustion gases and reducing the substrate temperature, are widely used in aerospace and other fields.

Present Status and Future Plan at High Magnetic Field Laboratory in Osaka University

We report on the development of experimental apparatus and the achievement of our research since 2006 when we reported “the present status and future plan of research in high magnetic fields” at the RHMF 2006 conference, after brief introduction of history and facility of the High Magnetic Field Laboratory at KYOKUGEN in Osaka University. As for our high-field and multi-frequency electron spin resonance (ESR) apparatus, we have expanded the magnetic field range up to 65 T and the frequency range up to 6 THz. In addition, ultra low temperature ESR apparatus down to 0.1 K for static fields and down to 0.6 K for pulsed fields have been fabricated. Furthermore, we have constructed a wide bore pulse magnet with the bore diameter of 48 mm? that enables us to perform resistivity measurements, which have been improved with the signal to noise ratio more than 100 times, under high pressure utilizing a diamond anvil pressure cell.

An All-Scale Hierarchical Architecture Induces Colossal Room-Temperature Electrocaloric Effect at Ultralow Electric Field in Polymer Nanocomposites

Composed of electrocaloric (EC) ceramics and polymers, polymer composites with high EC performances are considered as promising candidates for next-generation all-solid-state cooling devices. Their mass application is limited by the low EC strength, which requires very high operational voltage to induce appreciable temperature change. Here, an all-scale hierarchical architecture is proposed and demonstrated to achieve high EC strength in poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)-based nanocomposites. On the atomic scale, highly polarizable hierarchical interfaces are induced by incorporating BiFeO₃ (BFO) nanoparticles in Ba(Zr_0.21Ti_0.79)O₃ (BZT) nanofibers (BFO@BZT_nfs); on the microscopic scale, percolation of the interfaces further raises the polarization of the composite nanofibers; on the mesoscopic scale, orthotropic orientation of BFO@BZT_nfs leads to much enhanced breakdown strength of the nanocomposites. As a result, an ultrahigh EC strength of ≈0.22 K m MV⁻¹ is obtained at an ultralow electric field of 75 MV m⁻¹ in nanocomposites filled with the orthotropic composite nanofibers, which is by far the highest value achieved in polymer nanocomposites at a moderate electric field. Results of high-angle annular dark-field scanning transmission electron microscopy, in situ scanning Kelvin probe microscopy characterization, and phase-field simulations all indicate that the much enhanced EC performances can be attributed to the all-scale hierarchical structures of the nanocomposite.     

Understanding barriers to BIM implementation: Their impact across organizational levels in relation to BIM maturity

This multiple case study of a contracting firm contributes to understanding the barriers that organizations face during the implementation of building information modeling (BIM) by providing insights into the impact of these barriers across different organizational levels (i.e., from top management to project teams) and by relating these barriers to different degrees of BIM maturity. First, we observe the dominance of barriers related to the motivation, competence, and time capacity of people across all levels of an organization. Second, the cluster of barriers at the middle-management level highlights the important role of this level in reducing these barriers. Third, only those cases with a low level of BIM maturity have struggled with lack of top management support, thereby highlighting the importance of such support in achieving BIM maturity growth. High BIM maturity situations are more prone to externally oriented barriers in attempting to further leverage the benefits of BIM. Our study provides insights on where to focus BIM implementation measures and how to enhance organizational BIM maturity.
