Unveiling the Aging Effect at the Interface of N719 Dye‐Sensitized Solar Cells

Advanced Materials Interfaces, EarlyView.
Iodide is incorporated into the N719 layer through two mechanisms: the known ligand exchange of NCS with I and a second yet unknown mechanism which significantly blocks the charge regeneration process of the N719 dye contributing to the cell degradation.

Development of Kabila rocket: A radioisotope heated thermionic plasma rocket engine

Chinese Journal of Aeronautics, 2015
AbstractA new type of plasma rocket engine, the Kabila rocket, using a radioisotope heated thermionic heating chamber instead of a conventional combustion chamber or catalyst bed is introduced and it achieves specific impulses similar to the ones of conventional solid and bipropellant rockets.
