Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

open access: yesSmall, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

Long-Term Outcomes of Triple Cannulated Compression Screws Combined With Bone Graft Sleeve Parallel Implantation of DBM Crunch Internal Fixation for the Treatment of Femoral Neck Fractures in Middle-Aged and Young Adults. [PDF]

open access: yesOrthop Surg
This study compared the therapeutic effects of two internal fixation methods, including triple cannulated screws combined with a bone graft sleeve for parallel implantation of DBM Crunch internal fixation (CCSBGS), and cannulated compression screws (CCS). Fracture reduction and CCS fixation were the same as those in the CCS group.

Versatile High‐Sensitivity EPR Using Superconducting Spiral Microresonators

open access: yesSmall Methods, EarlyView.
A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.

Defining double burden of malnutrition across individual, household and population level: A narrative review

open access: yesNutrition &Dietetics, EarlyView.
Abstract Aims This study aims to evaluate the existing definitions of double burden of malnutrition and to synthesise and propose operational definitions at different levels, with the goal of improving consistency in measurement and policy development. Methods We conducted a narrative review that used structured search and narrative synthesis to review

Pregnancy Outcomes in Women Diagnosed With Attention‐Deficit/Hyperactivity Disorder: A Population‐Based Register Study

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background Maternal attention‐deficit/hyperactivity disorder (ADHD) has been associated with various pregnancy outcomes, but the degree to which that association is explained by concomitant mental disorders and smoking during pregnancy remains unclear.

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire

open access: yesArchaeometry, EarlyView.
ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.
