That tiny, plastic-looking atramentous cube up there can blot up to 180 times its own weight in baneful decay without arresting any water. How? As with just about every amazing and/or baffling accurate advance nowadays, the acknowledgment is spelled N-A-N-O.
Researchers at the Peking and Tsinghua Universities accept acclimatized carbon nanotubes into a sponge-like actual which can be awkward dry, which sounds like extremely agitative account for the infomercial charwoman artefact industry. One accessory detail:
since carbon nanotubes are hydrophobic, there's no modification appropriate to accomplish them not blot water.
For the record, that includes mysteriously dejected infomercial audience water, so there goes that. If not ABSORBING 20 TIMES AS MUCH WATER AS ITS LEADING COMPETITOR, what absolutely is this new blazon of blot acceptable for? Environmental cleanup, evidently. See, instead of just bottomward dispersants into the average of an oil or actinic spill—which armament the discharge to artlessly blot into the water—these nanosponges could be acclimated to sop up the spill, afterwards which they could apparently be afraid dry and reused, like so:
It's an amazing idea, but I get the activity that carbon nanotube sponges, alarmingly abbreviated as CNT sponges, aren't absolutely cheap. [Materials View via Treehugger]
