Hello everyone. I am trying to isolate heavy water from regular tap water. It turns out to be much more difficult than I expected. Anyone have some advice or a relatively inexpensive method of doing this?

Thats it? Does it rise exponentially with experience?

They have a private jet?

Roughly how much does a Cern physicist or other scientist make each year?

Forget that. Would water combined with solid bismouth cause pure water to pass through a selectively permeable membrane.

Quick question before I put my picture up. Is ferrofluid repelled by a magnet? If it is can it be mixed in water?

How do I put a picture up?

Two containers are connected, divided by a selectively permeable membrane. The continer on the left contains pure water. The container on the right contains water and a negatively charged solute. The container on the right is angeled vertically so that when the water diffuses across the membrane...

Selectively permeable for either positve or negative molecules. I need the membrane to cause osmosis.

Is it possible to create an artifical selectively permeable membrane? I need one for a science fair project idea I had.
