Effect of Solar Activity Regions on the Interplanetary Magnetic Field.

The Astrophysical Journal, 1963
A correlation between the solar activity regtons and the Pioneer V interplanetary magnetic field measurements is presented for the months February through May, 1960. The usual 27-day coronal periodicity can be seen in this interval. The corresponding vaiues of coronal index and field magnitude are plotted against each other and the ratio of the field ...

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

Advanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...
