Electrocatalytic conversion of lithium polysulfides by highly dispersed ultrafine Mo2C nanoparticles on hollow N‐doped carbon flowers for Li‐S batteries

open access: yesEcoMat, 2020
The significant challenge in exploring novel nanostructured sulfur host materials for Li‐S batteries is to simultaneously mitigate the notorious shuttle effect and catalytically enhance the redox kinetics of lithium polysulfides (LPSs).

Fluorine abundances in planetary nebulae [PDF]

open access: yesAstrophys.J.631:L61-L64,2005, 2005
We have determined fluorine abundances from the F II 4789 and F IV 4060 nebular emission lines for a sample of planetary nebulae (PNe). Our results show that fluorine is generally overabundant in PNe, thus providing new evidence for the synthesis of fluorine in asymptotic giant branch (AGB) stars. [F/O] is found to be positively correlated with the C/O

Fluorination Reaction of Uranium Dioxide by Fluorine [PDF]

open access: yesJournal of Nuclear Science and Technology, 2004
Kinetics of the fluorination reaction of uranium dioxide is studied using un-reacted core model with shrinking particles. The model includes the film mass transfer of fluorine gas and its diffusion in the particle. The rate constants of the model are determined by fitting the experimental data for 370–450°C.
