Flexible fluorinated graphite foils with high contents of the (CF) phase for slow neutron reflectors.

In order to prepare self-standing and flexible slow neutron reflectors made of graphite fluoride (GF) with high contents of (CF) structural phase, graphite foils of different thicknesses were used as starting materials for gas (F)/solid fluorination. The maximal interlayer distance of GF was obtained with this phase thanks to the stacking sequence FCCF/FCCF; this is mandatory for the efficient reflection of slow neutrons. 71 and 77% of the (CF) phase were achieved for graphite foils with thicknesses of 1.

High Energy Density of Ball-Milled Fluorinated Carbon Nanofibers as Cathode in Primary Lithium Batteries.

Sub-fluorinated carbon nanofibers (F-CNFs) can be described as a non-fluorinated core surrounded by a fluorocarbon lattice. The core ensures the electron flux in the cathode during the electrochemical discharge in the primary lithium battery, which allows a high-power density to be reached. The ball-milling in an inert gas (Ar) of these F-CNFs adds a second level of conductive sp carbons, i.

[End-of-life and advance healthcare directives].

In the context of the care of people at the end of life, the implementation of measures relating to advance healthcare directives still appears to be problematic. A nursing team in Saône-et-Loire carried out a research project on this issue and highlighted several obstacles: poor knowledge of the law, a lack of information among the general public, the sensitivity of the subject, etc. The project revealed avenues for further reflection now being explored.
