#4 Germaine Greer

1) Was an Australian feminist author who wrote The Female Eunuch, which is apparently one of the most significant works of feminist literature.
2) She was an anarchist communist.
3) Her feminism was not about equality with men but women’s liberation, sexual and otherwise.

*At one point was arrested for using the words “bullshit” and “fuck” during her speech (which is not a vitally important fact, but I am, apparently, three years old :P )



#3 Activated charcoal and its use in filters

1. Activated charcoal is charcoal treated with oxygen in order to make it porous. First it’s heated in an oxygenless area, and then treated with oxygen.

2. Um, since it has pores, it’s surface is bigger and tere are more bonding sites for other particles to bond with it, and that’s how it does the filtering . It’s called adsorption. I feel like a three years old trying to explain this to myself, but I’ve always sucked at chemistry and always will…

3. The activated charcoal ‘attracts’ the contaminant particles. It can filter them physically (some molecules literally get stuck in the pores) or chemically. Basically, I don’t really understand the chemical part. It has more success with organic molecules because it itself is organic and in this case similar tends to bond with similar (for some reason). Physical attraction has something to do with van der Waals forces, but that may be another entry.



#2 Gas Mask

1. Apparently, they age. The filter gets old. It’s not a good idea to use an old gas mask.

2. Up to 1950s they used blue asbestos in making of gas masks, which is apparently toxic. They don’t any more. Once again, not a good idea to try and use an old one.

3. The filter can work on several principles. For biological threats like anthrax, it uses particle filtration. Apparently, bacteria are larger than the filter openings.

For organic threats, activated charcoal is used. It bonds somehow the organic particles (organic, being based on carbon, I’m guessing it’s got something to do with positive and negative charge, but I’m making that into another entry. It’s not cheating. Shutup.)

For nonorganic threats, filters that are used are based on chemical reactions. Differently made filter for a different threat.



#1 Malic acid

Lots of chemistry stuff in Wikipedie, duh. Don’t understand a word of it. So, from some other sources, translated to dummy-captain language, because I wouldn’t get it otherwise.

1. It is crucial in some energy-producing processes in cells (actually, in mytochondrias).

2. It’s also used in aging the wine.

3. It can be used for detoxifying (esp. helps you get rid of aluminium in your body).
