Zero field optical magnetic resonance study of phosphorus donors in 28-silicon

open access: yes, 2018
Donor spins in silicon are some of the most promising qubits for upcoming solid-state quantum technologies. The nuclear spins of phosphorus donors in enriched silicon have among the longest coherence times of any solid-state system as well as ...

How are Forbush decreases related with IP magnetic field enhancements ? [PDF]

open access: yesarXiv, 2014
Cosmic ray Forbush decreases (FDs) are usually thought to be due to Earth-directed coronal mass ejections (CMEs) from the Sun and their associated shocks. When CMEs and their shocks reach the Earth, they cause magnetic field compressions. We seek to understand the relation between these magnetic field compressions and FDs at rigidities between 12 and ...

Evolution and Reconstruction of Air‐Electrode Surface Composition in Reversible Protonic Ceramic Cells: Mechanisms, Impacts on Catalytic Performance, and Optimization Strategies – A Review

open access: yesAdvanced Materials, Volume 37, Issue 11, March 19, 2025.
This review comprehensively summarizes the surface evolution and reconstruction of reversible protonic ceramic cell (R‐PCC) air‐electrodes. It begins by analyzing the thermodynamic and kinetic contributions to surface evolutions, followed by a summary of factors that lead to electrochemical performance degradation, emphasizing on both the negative and ...

Some theoretical aspects of the two-level magnetovariational method

open access: yesAnnals of Geophysics, 1997
We discuss some theoretical aspects of the two-level magnetovariational method for the determination of the underground electrical structure. The properties of two new apparent resistivity functions, respectively depending on gain and phase of the ...

The magnetic field within the earth [PDF]

open access: yesProceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949
The paper discusses the magnetic effects of internal motions in the core of the earth. It is shown that tidal friction, fluctuations in the rate of rotation, nutation, and the variation of latitude have negligible magnetic effects. Precession is also ineffective if Poincare’s theorem on the precession of a liquid sphere in a rigid shell is applicable ...

10 Years Development of Potassium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of
