252 Cf is a very strong neutron emitter, which makes it extremely radioactive and harmful. [24] [25] [26] 252 Cf, 96.9% of the time, alpha decays to curium-248; the other 3.1% of decays are spontaneous fission. [11] One microgram (μg) of 252 Cf emits 2.3 million neutrons per second, an average of 3.7 neutrons per spontaneous fission. [27]
The structure of fluorographene can be derived from the structure of graphite monofluoride (CF) n, which consists of weakly bound stacked fluorographene layers, and its most stable conformation (predicted for the monocrystal) contains an infinite array of trans-linked cyclohexane chairs with covalent C–F bonds in an AB stacking sequence.

Carbon is stable in a fluorine atmosphere up to about 400 °C, but between 420-600 °C a reaction takes place to give substoichiometric carbon monofluoride, CF 0.68 appearing dark grey. With increasing temperature and fluorine pressure stoichiometries up to CF 1.12 are formed. With increasing fluorine content the colour changes from dark grey ...
By the early 1990s, the Con-way companies were doing well, representing about US$600 million of CF's revenue, and CF's long-haul operation, CF MotorFreight, was successful as well. However, they were dragged down by Emery leading CF to a company-wide loss of US$41 million with a debt load of US$614 million in 1990.
Californium-252 (Cf-252, 252 Cf) undergoes spontaneous fission with a branching ratio of 3.09% and is used in small neutron sources. Fission neutrons have an energy range of 0 to 13 MeV with a mean value of 2.3 MeV and a most probable value of 1 MeV.
