A nanotube membrane also has the advantage of simplicity. Some companies, such as Denmark’s Aquaporin, are working on molecular filters that rely on a synthetic version of a natural protein called an aquaporin. Although scientists have struggled with making reasonably uniform carbon...
Water is a polar molecule consisting of two hydrogen atoms and one oxygen atom. Although its net charge is zero, the molecule has a positive side (hydrogen) and a negative side (oxygen). This polarity causes the molecule to orient in a particular direction when in the presence of an electri...
A while back I asked a member of the LLNL team what the best investment of dollars would be for research in this field. He said that the best investment currently would be “in coming up with scalable (economical) processes for producing membranes that use nanotubes or other useful nanomate...
