Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

REPORT OF COSMIC-RAY NEUTRON OBSERVATION IN THE 8TH JAPANESE ANTARCTIC RESEARCH EXPEDITION 1967-1968

open access: yesAntarctic Record, 1969
At Syowa Station, Antarctica, the cosmic-ray neutron observation was made, at the initial stage, with the IGY-type neutron monitor during the period from March 1960 to December 1961.

Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

open access: yesAdvanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Surface Temperature of Magnetized Neutron Stars

open access: yes, 1996
We show that the expected inhomogeneous temperature distribution induced at the surface of a neutron star by the anisotropy of heat transport in the magnetized envelope allows us to understand quite well the observed pulse profiles of the four nearby pulsars for which surface thermal emission has been detected.

Mirror Coating Research and Developments for Current and Future Gravitational‐Wave Detectors

open access: yesAdvanced Photonics Research, EarlyView.
In gravitational‐wave detectors, research on mirror coatings is needed to mitigate thermal noise and enhance the detectors’ sensitivity. In this review, an overview of the latest worldwide research activities on coatings with low mechanical loss and low optical absorption is presented, including new coating designs such as multimaterial coatings and ...

High‐Speed Embedded Ink Writing of Anatomic‐Size Organ Constructs

open access: yesAdvanced Science, EarlyView.
A high‐speed embedded ink writing approach is proposed, which is powered by the development of a particle‐hydrogel interactive system to design suitable yield‐stress fluids. Using this approach, an anatomic‐size human kidney analog is printed in only 4.2 h at the speed ten times higher than the printing speed barrier of current methods, demonstrating ...

Brightened Optical Transition Hinting to Strong Spin‐Lattice Coupling in a Layered Antiferromagnet

open access: yesAdvanced Science, EarlyView.
The study reveals an unreported luminescent transition in CrPS4, a 2D antiferromagnetic semiconductor, near its Néel temperature. This transition arises from changes in Cr3+ octahedral crystal field distortion, shifting from anti‐polar to polar. It enhances the dipole moment and second harmonic generation intensity, suggesting a multiferroic state ...
