The critical current of disordered superconductors near 0 K

open access: yesNature Communications, 2020
Increasing the critical current of superconductors has been a central scientific effort, but the fundamental understanding of critical currents near 0 K is lacking. Here, Doron et al.

Imaging of Lipid Droplets in Living Cells and Mice with Metabolic Dysfunction‐Associated Steatotic Liver Disease via a Galactose‐Modified Supramolecular Near‐Infrared Fluorescent Glycoprobe

open access: yesAdvanced Functional Materials, EarlyView.
A galactose‐modified supramolecular near‐infrared (NIR) glycoprobe, TCF‐FBN@Gal‐BSA, enables targeted delivery to the liver through the asialoglycoprotein receptor (ASGPR) and facilitates liver‐targeting fluorescence visualization of lipid droplets (LDs) in metabolic dysfunction‐associated steatotic liver disease (MASLD) mice.

Absence of diode effect in chiral type-I superconductor NbGe2

open access: yesCommunications Physics
Symmetry elegantly governs the fundamental properties and derived functionalities of condensed matter. For instance, realizing the superconducting diode effect (SDE) demands breaking space-inversion and time-reversal symmetries simultaneously.

A route for a strong increase of critical current in nanostrained iron-based superconductors

open access: yesNature Communications, 2016
Simultaneous increase of critical temperature and critical current in superconductors is desirable for application purpose, but very difficult to realize. Here, Ozaki et al. report a simultaneous enhancement of Tc and Jc in FeSe0.5Te0.5films with cascade

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Preparing high-concentration individualized carbon nanotubes for industrial separation of multiple single-chirality species

open access: yesNature Communications, 2023
Industrial production of single-chirality carbon nanotubes is critical for their applications in high-speed and low-power nanoelectronic devices, but both their growth and separation have been major challenges.
