The ionospheric responses to the 11 August 1999 solar eclipse: observations and modeling [PDF]

open access: yesAnnales Geophysicae, 2008
A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40°–50° N. The ionospheric responses to this eclipse were measured by a wide ionosonde network.

Cr3+‐Doped γ‐ and β‐Gallium Oxide Nanoprobes for Bioimaging: Synthesis, Persistent Luminescence, and Biocompatibility

open access: yesAdvanced Optical Materials, EarlyView.
γ‐Ga2O3:Cr3+ nanospheres are synthesized and transformed into colloidal β‐Ga2O3:Cr3+ nanoparticles (NPs) enabling to establish the relationships between their crystal structures and their NIR photoluminescence and persistent luminescence (PersL). Cytotoxicity and in vivo toxicity studies indicate that β‐Ga2O3:Cr3+ NPs are adequate nanoprobes for ...

Fingerless [PDF]

open access: yes, 2017
This reflective poem about the self and being in a new area is based on the total solar eclipse (dubbed the Great American Eclipse) that occurred on August 21, 2017. It explores themes similar to those raised in discussions about the case of Charity Lamb.

Application of a Dynamic Semitransparent Agrivoltaic Panel for Controlling Sunlight Allocation to Solar Cells and Crops

open access: yesAdvanced Sustainable Systems, EarlyView.
Effects of dynamic agrivoltaic semitransparency controls on cucumber seedling growth are assessed for this study using a micro‐cell photovoltaic panel. Seedling growth with 9:30–14:30 agrivoltaic shading is comparable to that without shading. The dynamic shading regulates the electrical energy and crop production allocation.

The dynamic effects of solar eclipses of October 25, 2022, and October 14, 2023, on GPS-derived total electron content

open access: yesGeodesy and Geodynamics
This study analyzes total electron content (TEC) variations during two solar eclipse events that occurred on October 25, 2022, and October 14, 2023. The solar eclipse of October 25, 2022, was a partial solar eclipse, while the eclipse of October 14, 2023,

Search for Rapid Changes in the Visible-Light Corona during the 21 June 2001 Total Solar Eclipse [PDF]

open access: yes, 2010
Some 8000 images obtained with the SECIS fast-frame CCD camera instrument located at Lusaka, Zambia, during the total eclipse of 21 June 2001 have been analyzed to search for short-period oscillations in intensity that could be a signature of solar ...
