Effect of multi-donor doping on structure and electrical properties of DC ZnO varistor ceramics
Direct-current ZnO varistor ceramic samples were prepared by traditional ceramic sintering process with B2O3, In2O3 and Al2O3multi-donor doping. The effects of B2O3 doping ratio (0.1%-0.4%, molar fraction) on the microstructure and electrical properties ...

Dynamics of solar wind protons reflected by the Moon [PDF]
Solar system bodies that lack a significant atmosphere and significant internal magnetic fields, such as the Moon and asteroids, have been considered as passive absorbers of the solar wind. However, ion observations near the Moon by the SELENE spacecraft

Solar wind–magnetosphere coupling efficiency for solar wind pressure impulses [PDF]
We investigate the solar wind–magnetosphere coupling efficiency in response to solar wind dynamic pressure impulses. We carry out a superposed epoch analysis of 236 pressure impulses from the years 1998–2002 detected by the ACE/SWEPAM instrument. For the coupling efficiency, we use four definitions based on: the polar cap potential from SuperDARN ...

The Mother’s Day Solar Storm of 11 May 2024 and Its Effect on Earth’s Radiation Belts
The month of May 2024 was characterized by solar energetic particles events directed towards the Earth, especially the big event causing a strong terrestrial geomagnetic storm during the night from 10 to 11 May 2024, with auroras observed everywhere in ...

Recurrent geomagnetic storms and relativistic electron enhancements in the outer magnetosphere: ISTP coordinated measurements [PDF]
New, coordinated measurements from the International Solar-Terrestrial Physics (ISTP) constellation of spacecraft are presented to show the causes and effects of recurrent geomagnetic activity during recent solar minimum conditions.

A low leakage current (Co, Mn, Ta)-SnO2 varistor tailored by doping with chromium for power grids
A SnO2 varistor which was prospected to be used in ultra-high voltages grids as an overvoltage protection element was developed. The SnO2 varistor was doped with Cr to improve the comprehensive electrical properties. The optimal electrical parameters are

Lithium-6 from Solar Flares [PDF]
By introducing a hitherto ignored Li-6 producing process, due to accelerated He-3 reactions with He-4, we show that accelerated particle interactions in solar flares produce much more Li-6 than Li-7.

The Solar Wind Energy Flux [PDF]
The solar-wind energy flux measured near the ecliptic is known to be independent of the solar-wind speed. Using plasma data from Helios, Ulysses, and Wind covering a large range of latitudes and time, we show that the solar-wind energy flux is independent of the solar-wind speed and latitude within 10%, and that this quantity varies weakly over the ...
