High Coherence Times in NV‐Doped Diamond Films for Quantum Sensing
physica status solidi (a), Volume 223, Issue 2, January 2026.This study demonstrates the growth of micrometer‐thin diamond films with nitrogen‐vacancy centers exhibiting record‐long spin coherence times at room temperature. By combining isotopic purification, controlled nitrogen incorporation, and strain minimization, the authors achieve coherence times approaching theoretical limits, paving the way for highly ...

Placement of Nitrogen‐Vacancy‐Centers in Diamond Through Chemical Vapor Deposition Growth Techniques
physica status solidi (a), Volume 223, Issue 2, January 2026.Chemical vapor deposition techniques for precise nitrogen‐vacancy (NV) center positioning in diamond for quantum applications are reviewed. Delta‐doped layer fabrication achieves vertical positioning accuracy, while advanced methods provide full spatial control over NV placement.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.To address nonlinearity in high‐voltage flat‐wire EV motors, a new layering theory is developed for calculating stator natural frequency and frequency response functions. The method is validated by finite element analysis and experimental hammering tests, showing a significant improvement in simulation accuracy to within 1% for natural frequencies ...
