With the exception of the present study, the influence of solar activity on high-frequency paleoenvironmental evolution in other parts of the globe has not been reported in the Triassic. Whether solar activity had a global effect on paleoenvironmental evolution is yet to be verified in other areas...
Solar eruptive activities, mainly including solar flares, coronal mass ejections (CME), and solar proton events (SPE), have an important impact on space weather and our technosphere. The short-term solar eruptive activity prediction is an active field of research in the space weather prediction....
The Earth’s magnetosphere provides a global magnetic shield protecting life on our planet from the hazardous flow of solar wind plasma. This shield is not perfect: solar wind particles and interplanetary magnetic field flux may penetrate inside the magnetosphere and accumulate there, causing magnetic...
Several studies on volcanic activity and solar activity, greenhouse gas increase and digital simulation have been completed so far27,28,29,30,31,32,33,34,35,36, which have revealed the operational mechanism of a certain aspect of AO/NAO formation. These studies are interdecadal or interannual ...

Existing sensitized solar cells appear to have a life span of about 2 years whereas a ruthenium complex also has photoelectrochemical degradation. This incident seems to be mainly reliant on the surface bonding and hence the superiority of the adsorption site of the molecules involved [13]. ...
