RE 4Al13Pt9—New Representatives in the RE–Al–Pt System with the Ho4Ge9Ir13‐Type Structure (RE = Y, La‐Nd, Sm, Gd‐Dy)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The RE4Al13Pt9 series has been extended to RE = Y, La‐Nd, Sm, Gd‐Dy. The compounds have been investigated by X‐ray diffraction and magnetic susceptibility measurements. Of the RE4Al13Pt9 series, the RE = Ce, Pr, and Eu representatives were previously reported. In this work we extend the series to RE = Y, La‐Nd, Sm, Gd‐Dy.

Design of optimized tread profile for high-speed EMUs

To address two significant issues in high-speed electric multiple units (EMU), i.e. degraded vehicle dynamic performance under existing wheel-rail interactions and increased wheel tread wear at elevated operating speeds, this paper proposes an optimized tread profile design that balances wheel-rail interactions, dynamic performance, and wear resistance.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Differentiated by Design? Cross‐Border Cooperation in Europe as Differentiated Integration From Below

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Differentiated integration has become a central concept in contemporary theorizing about European integration, reflecting the increasingly multi‐speed, multi‐tier and multi‐menu nature of integration within the European Union (EU). This research note extends the conceptual lens of differentiated integration to the level of cross‐border regions.

The changing landscape of training in microscopy facilities: Reflections on seven decades of research user support at the University of Sydney

Journal of Microscopy, EarlyView.
Abstract This thematic contribution highlights the critical role of established professional training regimes in microscopy and microanalysis in supporting high‐quality research. As microscopy technologies continue to evolve in complexity, the risk of mishandling and data misinterpretation by inexperienced researchers increases significantly.

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Study of Wheel-slide-protection Strategy of High-speed EMUs

, 2017
Wheel-slide-protection control is one of the core technologies for the high-speed EMUs brake system. The effective and reliable wheel-slide-protection strategy can not only avoid the wheel tread flat, and protect the safety of the vehicle equipments, but also can take advantage of adhension force between wheel and rail to guarantee braking distance ...
