Atmospheric Gravity Waves Observed in the Nightglow Following the 21 August 2017 Total Solar Eclipse

Geophysical Research Letters, 2020
Nighttime airglow images observed at the low‐latitude site of São João do Cariri (7.4°S, 36.5°W) showed the presence of a medium‐scale atmospheric gravity wave (AGW) associated with the 21 August 2017 total solar eclipse.

Piezoceramics Boosting Photocatalytic Hydrogen Evolution of Covalent Organic Frameworks

Advanced Science, EarlyView.
This study develops a core‐shell Z‐scheme piezo‐photocatalyst using covalent interfacial bridging between piezoelectric ceramics and covalent organic frameworks. Proper band alignment enables efficient electron transfer and internal electric field formation, while piezoelectricity generates a polarization field under ultrasound, enhancing solar energy ...

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

Advanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

Analysis of penumbral eclipse data [PDF]

, 1977
Two days of data from the ATS-6 1976 eclipse season were analyzed to determine the effects of varying photoelectron flux on spacecraft potential. Particular emphasis was placed on the variation in potential as the satellite entered the earth's penumbra ...
