Analysis of Multi‐Component Echo Decay in Achilles Tendon by NMR Spectroscopy

open access: yesNMR in Biomedicine, Volume 39, Issue 4, April 2026.
The Achilles tendon was modeled as a set of water‐filled nanocavities. Here, ζ denotes the angle between the main axis ZC of a nanocavity and the normal N to the sample surface; the normal is parallel to the magnetic field H0. The structural and dynamic parameters of the nanocavities were determined by analyzing the decay of a single NMR signal from ...

Electron‐Deficient Bimetallic Oxide Electrocatalyst for High‐Efficiency Ammonia Synthesis Under Ambient Conditions

open access: yesChemSusChem, Volume 19, Issue 6, 27 March 2026.
An eco‐friendly solid‐state synthesis of an electron‐deficient Bi4V6O21@CB electrocatalyst enables efficient electrochemical nitrogen reduction (NRR) to ammonia (NH3) under ambient conditions. The synergistic Bi–V–O framework and conductive carbon support enhance N2 activation and proton‐coupled electron transfer, enabling carbon‐free NH3 production ...

Molecular Dynamics in Tetrafluoridoborate Salts of Divalent Metals Studied by Nuclear Magnetic Resonance Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 5, 13 March 2026.
We studied molecular dynamics in four tetrafluoridoborate salts by means of nuclear magnetic resonance. Characteristical motions in these systems are thermally‐activated reorientations of BF4− ions. We determine the activation energies for these processes and compare the dynamics with those in borohydride systems that share the tetrahedral geometry of ...

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

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
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 ...
