FLiBe is a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF2). It is both a nuclear reactor coolant and solvent for fertile or fissile material. It served both purposes in the Molten-Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory. The 2:1 mixture forms a stoichiometric compound, Li2BeF4, which has a melting point of 459 °C, a boiling point of 1430 °C, and a density of 1.94 g/cm3. Its volumetric heat capacity is similar to that of water (4540 kJ/m3K = 1085 kcal/m3K): 8.5% more than the standard value considered for water at room temperature), more than four times that of sodium, and more than 200 times that of helium at typical reactor conditions. Its specific heat capacity is 2414.17 kJ/kg K, or about 60% that of water.Its appearance is white to transparent, with crystalline grains in a solid state, morphing into a completely clear liquid upon melting. However, soluble fluorides such as UF4 and NiF2, can dramatically change the salt's color in both solid and liquid state. This made spectrophotometry a viable analysis tool, and it was employed extensively during the MSRE operations. The eutectic mixture is slightly greater than 50% BeF2 and has a melting point of 360 °C. This mixture was never used in practice due to the overwhelming increase in viscosity caused by the BeF2 addition in the eutectic mixture. BeF2, which behaves as a glass, is only fluid in salt mixtures containing enough molar percent of Lewis base. Lewis bases, such as the alkali fluorides, will donate fluoride ions to the beryllium, breaking the glassy bonds which increase viscosity. In FLiBe, beryllium fluoride is able to sequester two fluoride ions from two lithium fluorides in a liquid state, converting it into the tetrafluorberyllate ion BeF4−2. (Wikipedia).

What is Flibanserin (AKA "Female Viagra")?
"Female Viagra" and regular or "male" Viagra were both originally investigated as treatments for conditions other than sexual dysfunction. Viagra came out of studies on hypertension, and "female Viagra" for depression. But… that's where most of the similarities end. How so? Let's discuss.

Addyi Isn't that Effective, and it Isn't Selling Very Well
No studies this week. We're actually going to do news. It's time for an Addyi update. Addyi, or Flibanserin was touted as the "female Viagra" despite the fact that it isn't very similar to Viagra. It still doesn't work very well or for very many patients. And it has a lot of side effects.
