Electronic Structures and Optical Properties of Partially and Fully Fluorinated Graphene [PDF]
Phys. Rev. Lett. 114, 047403 (2015), 2014 In this letter we study the electronic structures and optical properties of partially and fully fluorinated graphene by a combination of abinitio G0W0 calculations and large-scale multi-orbital tight-binding simulations. We find that for partially fluorinated graphene, the appearance of paired fluorine atoms is more favorable than unpaired atoms.

Superconductivity in WO2.6F0.4 synthesized by reaction of WO3 with Teflon [PDF]
Phys. Rev B 84, 174519 (2011), 2011 WO3-xFx (x < 0.45) perovskite-like oxyfluorides were prepared by a chemically reducing fluorination route using the polymer polytetrafluoroethylene (Teflon). The symmetry of the crystal structures of WO3-xFx changes from monoclinic to tetragonal to cubic as the fluorine content increases.

Plausibility of potassium ion-exchanged ZSM-5 as soot combustion catalysts
Scientific Reports, 2017 Potassium (K) ion-exchanged ZSM-5 zeolites were investigated for catalytic soot combustion. X-ray absorption fine-structure (XAFS), Raman, in situ IR and NH3-temperature programmed desorption (NH3-TPD) confirmed the location of K+ at the ion-exchanged ...

Effect of fluorine patterns on electronic transport in fluorinated graphene [PDF]
, 2019 Within the framework of stochastic reactive molecular dynamics simulations we develop a statistical method for generating fluorinated graphene structures with desirable fluorine distribution. Electronic transport properties of fluorinated graphene in a wide range of functionalization degree and system ordering are investigated.

On the cosmic origin of Fluorine [PDF]
, 2020 The cosmic origin of fluorine, the ninth element of the Periodic Table, is still under debate. The reason for this fact is the large difficulties in observing stellar diagnostic lines, which can be used for the determination of the fluorine abundance in stars.

Metal-Free Fluorine-Doped Carbon Electrocatalyst for CO2 Reduction Outcompeting Hydrogen Evolution.
Angewandte Chemie, 2018 The electrochemical CO2 reduction (ECDRR), as a key reaction in artificial photosynthesis to implement renewable energy conversion/storage, has been inhibited by the low efficiency and high costs of the electrocatalysts.
