Fluorine is the chemical element we will focus on today, atomic number 9 and symbol F. We are talking about the most electronegative element in the periodic table, the only one capable of oxidizing oxygen. Elemental fluorine at room temperature is a pale yellow gas, slightly heavier than air, toxic, extremely aggressive and with a pungent odor.
Many products containing fluorine have been marketed since the 1960s:
- Low friction plastics such as PTFE.
- High resistivity non-flammable polymeric products, for example for the sheaths of electric cables.
- Transparent plastics with a high refractive index for polymeric optical fibers.
- Lubricants for extreme conditions, such as those used to lubricate the Mars Pathfinder probe
- Coolants such as freon. Hydrofluorochlorocarbons are used extensively in air conditioning and refrigeration systems. Chlorofluorocarbons have been banned for these applications because they are suspected of contributing to the formation of the ozone hole. Both of these classes of compounds are potent greenhouse gases. Fluorine is used to produce new low environmental impact refrigerants such as hydrofluoroethers.
- Fluorine is often a substitute for hydrogen in organic compounds. In medicines, it multiplies the therapeutic efficacy and at the same time delays the metabolization of the active ingredient. It is estimated that about 20% of pharmaceutical products currently on the market contain one or more fluorine atoms.
- Together with other halogens it is very common in anesthetic substances.
- As an anti-caries agent in toothpastes and mouthwashes.
- Hydrofluoric acid (HF) is used to etch the glass of light bulbs and other products.
- In the semiconductor industry.
- In fuel cell membranes and membrane cells for chlorine production.
- In Li-Ion and Li-Polyr batteries.
Fluoride and hydrofluoric acid must be handled with great care and any contact with skin and eyes should be avoided. Very strict safety procedures allow the transport of liquid or gaseous fluorine in large quantities.
For this reason we decided that we could not afford a large amount of Fluorine NFT. The maximum supply of this NFT is 149 and 30 NFTs will be allocated to this giveaway:
- 25 NFTs will be given to the first 25 readers who will leave their wax address in the comments
- the other 5 NFTs will be randomly given away among all the others who will leave their wax address in the comments by Monday 26 October at 14:00 CEST and who, at that date / time, will have 6 different NFT elements in their portfolio (the verification procedure will be done manually so I recommend not to sell the elements before 16:00 pm CEST ;-) )
The previous Oxygen NFT giveaway sold out in 14 hours, giving away 40 NFTs and excluding others interested. For this giveaway we have decided not to do any promotions and leave it to Publish0x readers to discover the opening.
The Periodic Table NFT project
The Periodic Table NFT project aims to raise awareness of chemical elements in a modern key, basing the approach on blockchain and Non Fungible Token.
Day after day it will be possible to know the single elements that make up the table, to collect curiosities about each of them and about the table in general.
We are working to be able to learn, in a playful way, also what happens by combining the various elements.
The whole project is based on the collection of NFTs that can be bought on the site https://wax.atomichub.io/market?collection_name=periodicelem&order=desc&sort=created&symbol=WAX or by participating in simple giveaways published on publish0x.
