[Special Issue Report] Prevalence of small-scale jets from the networks of the solar transition region and chromosphere

17-10-2014 | H. Tian; E. E. DeLuca; S. R. Cranmer; B. De Pontieu; H. Peter; J. Martínez-Sykora; L. Golub; S. McKillop; K. K. Reev ..., Science , 2014

As the interface between the Sun’s photosphere and corona, the chromosphere and transition region play a key role in the formation and acceleration of the solar wind. Observations from the Interface Region Imaging Spectrograph reveal the prevalence of intermittent small-scale jets with speeds of ...

Ca2Mn2O5 as Oxygen-Deficient Perovskite Electrocatalyst for Oxygen Evolution Reaction

14-10-2014 | Jaemin Kim; Xi Yin; Kai-Chieh Tsao; Shaohua Fang; Hong Yang, Journal of the American Chemical Society, 2014

This paper presents the use of Ca2Mn2O5 as an oxygen-deficient perovskite electrocatalyst for oxygen evolution reaction (OER) in alkaline media. Phase-pure Ca2Mn2O5 was made under mild reaction temperatures through a reductive annealing method. This oxygen deficient perovskite can catalyze the ...
