Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

open access: yesAdvanced Functional Materials, EarlyView.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

Quantitative Analysis of Slow-extraction Spill Spectrum and Its Application

open access: yesYuanzineng kexue jishu, 2022
Slow extraction from synchrotrons is widely used for delivering hadron beams to many physical experiments as well as hadron cancer therapy based on charged particle deposition on tumors. The extracted beam is also referred to as spill.

In situ Viscometry of Primitive Lunar Magmas at High Pressure and High Temperature

open access: yesFrontiers in Earth Science, 2019
Understanding the dynamics of the magmatic evolution of the interior of the Moon requires accurate knowledge of the viscosity (η) of lunar magmas at high pressure (P) and high temperature (T) conditions. Although the viscosities of terrestrial magmas are

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers

open access: yesAdvanced Functional Materials, EarlyView.
The metal–insulator transition temperature (TMI) is continuously tuned by the systematic change of relative thickness in VO2 and TiO2 films (tVO2/tTiO2${t_{{\mathrm{V}}{{\mathrm{O}}_2}}}/{t_{{\mathrm{Ti}}{{\mathrm{O}}_2}}}$) in freestanding TiO2/VO2/TiO2 tri‐layers.

3-Hydroxy-2-[(4-hydroxybenzyl)azaniumyl]propanoate monohydrate

open access: yesIUCrData, 2017
In the title hydrated zwitterion, C10H13NO4·H2O, the N—C—C—OH side chain shows a gauche conformation [torsion angle = −59.05 (18)°]. In the crystal, the components are linked by O—H...O, N—H...O and C—H...O hydrogen bonds to generate a three-dimensional ...

Point-like gamma ray sources as signatures of distant accelerators of ultra high energy cosmic rays

open access: yes, 2005
We discuss the possibility of observing distant accelerators of ultra high energy cosmic rays in synchrotron gamma rays. Protons propagating away from their acceleration sites produce extremely energetic electrons during photo-pion interactions with ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu

open access: yesAdvanced Functional Materials, EarlyView.
From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).
