I need to keep scientific samples (chips) in solution for weeks at a time, and they're growing bacteria. I suspect biologists have a good way of dealing with this, since they tend to do more solution work than I do; are any of you out there able to point me in the right direction in terms of UV lamps or something similar?

I need help understanding analysis of mass spectrometry and UV, IR, NMR spectroscopy readouts. I'm looking up tutorials on websites and re-reading my textbook, and while I think I understand the
theory behind each method I'm drawing a blank when it comes to actually interpreting results to complete problems.

I'd like to use a single 5mm UV LED
(3.4Vf, 20-25mA) to charge a daub of glow-in-the-dark paint. It only needs to be lit around 1 minute of every 10 (or 6 seconds of every 60), and only when the (room) lights are out. What battery/circuit would be most economical to operate, and require the least-frequent battery changes?

When are the sun's UV rays weaker: from 10am to 11am, or from 5pm to 6pm? (East coast USA, this month.) Beach has strict swimming hours, 10am-6pm. I'm looking for which is the better hour to go swimming -- regularly over the course of June -- in a bathing suit, very-wide-brimmed solid straw hat, and sunglasses, but no sunscreen.
