Here's one for you:
I read this when I was very young. It was written by a Russian guy, it was actually a collection of 3 novellas (or novels?). In one of them, this guy went to a space station. I remember vividly a paragraph where he had to go through a decontamination chamber, and then while in the space station he had a discussion about how even a grain-size meteor could kill them.
And in the second one, this maniac was absorbing all the oxygen in the atmosphere and had a plan for selling bottled oxygen to rich people.
Never got to reading the third one, because it was borrowed and I had to return it
