I wonder if this UCLA newly developed nano valve would store hydrogen? investorshub.com I don't see why not - though they don't mention it. Porous silica particles 500nm across with valving abilities to open and close at will. "The valve is like a mechanical system that we can control like a water faucet," said UCLA graduate student Thoi Nguyen, lead author on the paper. "Trapping the molecule inside and shutting the valve tightly was a challenge. The first valves we produced leaked slightly." "Thoi was a master nano plumber who plugged the leak with a tight valve," Zink said. This nano valve consists of moving parts — switchable rotaxane molecules that resemble linear motors designed by California NanoSystems Institute director Fraser Stoddart's team — attached to a tiny piece of glass (porous silica), which measures about 500 nanometers, and which Nguyen is currently reducing in size. Tiny pores in the glass are only a few nanometers in size. "It's big enough to let molecules in and out, but small enough so that the switchable rotaxane molecules can block the hole," Zink said.
