Autonomy for MRI Field Cameras: Synchronization, Self‐Calibration, and Sequence Detection

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences. Methods An independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position ...

Antiferromagnetic Chains in a Monolayer of Molecular Qubits Assembled on Graphene

Small, EarlyView.
This work explores the deposition onto graphene of a dithiazole‐based molecular qubit, [Cu(dttt)2], (dttt− = 1,3,2‐dithiazole‐4‐thione‐5‐thiolate), under ultra‐high vacuum conditions. Analytical techniques, including STM, XPS, and X‐ray absorption, reveal the molecular arrangement and magnetic interactions, emphasizing the role of vdW interactions in ...

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, Volume 38, Issue 20, 7 April 2026.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Optical Manipulation of Multiferroic Phases in BiFeO3 Thin Films

Advanced Materials Interfaces, Volume 13, Issue 7, 7 April 2026.
At the strain‐driven morphotropic phase boundary, optical control over the multiferroic rhombohedral and tetragonal phase mixture is demonstrated using above‐bandgap light illumination. The photoinduced charge carriers modify the electrostatic environment and induce the conversion into a single tetragonal phase.

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Engineering Asymmetry: How Chirality Boosts Catalysis, Spin Selectivity, and Light–Matter Interactions

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This review connects chiroptical spectroscopy, asymmetric catalysis, and spintronics, revealing how chirality influences the interactions of matter with light, charge, and spin. Across diverse systems, remarkable chiroptical effects emerge, showing among others that high efficiencies can arise without absolute enantiopurity, and that functionality is ...

Bio-sensing with NV-centers in diamond

JPhys Photonics
Color centers in diamond, most frequently the negatively charged nitrogen vacancy (NV ^− ) center, have demonstrated their applicability as optically actuated quantum sensors of e.g. temperature, magnetic field, or electrical fields. Further, the promise

Using biotelemetry to assess drone effects on whale sharks

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The use of unoccupied aerial vehicles or drones for wildlife research has proliferated in recent years and they have proven to be a valuable tool for collecting data for population surveys, morphometric and body condition measurements, and for observing behavior.
