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 ...

First Tellurite Composite Fiber with NIR‐Driven Green Persistent Luminescence
Advanced Optical Materials, EarlyView.The first composite fiber based on SrAl2O4:Eu2+, Dy3+ PeL phosphors embedded in Yb3+/Tm3+ co‐doped tellurite glass is developed. The fiber exhibits green afterglow driven by 980 nm laser injection, suggesting that the PeL phosphors survive the fabrication process and the blue upconversion from the Yb3+/Tm3+ co‐doped glass matrix is strong enough to ...

Advanced Optical Materials, EarlyView.Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Ionospheric response over Europe during the solar eclipse of March 20, 2015
Journal of Space Weather and Space Climate, 2016 The solar eclipse on March 20, 2015 was a fascinating event for people in Northern Europe. From a scientific point of view, the solar eclipse can be considered as an in situ experiment on the Earth’s upper atmosphere with a well-defined switching off and

Solar eclipse effects of 22 July 2009 on Sporadic-E [PDF]
Annales Geophysicae, 2010 The total solar eclipse of 22 July 2009, was visible from some regions of China and the intense sporadic-E (Es) that broke out during the solar eclipse period over the eastern China provided a unique chance to study solar eclipse effects on the Es ...

Advanced Science, EarlyView.An electrochemical system is designed to convert CO2 into CO2‐derived electrolytes (CDE), mainly containing acetate and formate. The underlying mechanism of acetate metabolism in Halomonas TD80 is explored via ALE. Engineered TD80 produced high‐yield diversified products from CDE.
