A research team at the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, has used scanning nitrogen-vacancy microscopy and vector magnetic field reconstruction to demonstrate at the nanoscale that zigzag graphene nanoribbons embedded in hexagonal boron nitride exhibit strong perpendicular magnetic anisotropy. The work was published in the Journal of Functional Materials and Devices.

In a paper published in Earth and Planetary Physics,a research team of seismologists explores strong earthquake hazards along major active faults on the western Ordos margin using multiple seismological methods. The sparse earthquake segments overlapping low b-value anomalies mark stress-loaded locked fault patches, interpreted as potential seismogenic asperities. Theoretical magnitudes estimated from the spatial extents of these sparse segments along the faults are broadly consistent with the magnitude range of historical strong earthquakes.

A Chinese research team has shown that a self-developed, transportable cold atom gravimeter can measure the strength of Earth's gravity as accurately as the world's mainstream laser-interferometer instruments. During a two-month comparison organized by China's Crustal Movement Observation Network (CMONOC) in Wuhan, the atom-based instrument, WAG-H5-2#2508, was tested side by side with eight conventional absolute gravimeters. Its result differed from the group consensus value by only 1.4 microGal, about one billionth of the surface gravity, confirming that mechanically wear-free atom interferometry is now ready for high-precision, long-term gravity monitoring.

In a comprehensive review published in Earth and Planetary Physics, researchers from Wuhan University synthesize recent advances in the climatological variations and complex driving mechanisms of the equatorial electrojet (EEJ). The study highlights how the daytime EEJ responds to E-region conductivity, atmospheric tides, and intense mid- and high-latitude electrodynamic disturbances.

A research team at the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences has proposed a method for optimizing superconducting integrated circuits based on “time scaling”. By constructing a dual-active-device layer within a single wafer, the researchers successfully transformed key logic paths from planar structures into vertically compressed ones, significantly reducing pulse propagation time and paving a new path for superconducting computing in the post-Moore’s Law era.
