Congruent biospheric and solar-terrestrial cycles

Solar Cells using Congruent Thermal Evaporation

Although highly valuable as an R&D tool, ALD is a rather slow and thus expensive fabrication method for growing fi lms on the order of 1 μm thick, posing a challenge to industrial scaleup. Hence, there is a need to transfer learnings from ALD to higher-throughput manufacturing techniques without compromising quality. We fi rst demonstrate the ease of phase purifi cation of commercial SnS powder...

Solar Flare Cycles

We present a review of different solar flare periodicity intervals. Our analysis includes a statistical investigation of flare occurrence and N-S hemispheric distribution over the last three 11-yr solar cycles (SCs 21-23, corresponding to the period 1976-2001). Moreover, we try to estimate if there is any connection between the flare activity and the strength of solar cycles. For that purpose, ...

The NASA Solar Terrestrial Relations

The NASA Solar Terrestrial Relations Observatory (STEREO) mission will place two spacecraft into solar orbits with sufficient separation to provide remote sensing instruments with a stereoscopic view of the heliosphere extending from the lower solar corona to beyond one astronomical unit. Analysis of the stereographs returned from the two spacecraft will allow solar physicists to infer the thre...
