At this point , it ’d be more of a surprise if graphene was n’t an constitutional part of a mind - bending , platter - set up raw technology . But , of course , it is . Again . Enter the lightest material in the world : graphene aerogel .
Aerogel isnothing new . All made primarily of air , dissimilar flavors of aerogel have been one - upping each other for the title of lightest for years now . The late disc holder was aerographite with a density of 0.18 milligram / cm3 , and now researchers atChina ’s Zhejiang Universityhave made some aerographene , which takes the crown with a compactness of 0.16 mg / cm3 .
Building chunk of the almost - but - not - quite weightless material involves some eminent - tech freeze drying that can relent graphene leech of arbitrary size . Professor Gao Chao , the research squad ’s drawing card , says the appendage can easily be scale up to an Holy Order of meters . And apart from being less dull than helium — an acheivement in and of itself — aerographene is extremely live and can mop up 900 clock time its weight in oil , making it potentially indispensable as a clean-living - up leech .
The sponge may not be as immediately useful as say , terabit - down graphene antennas , but if / when there ’s another awful fossil oil - spillway , aerographene will be worth far more than its weight in awesomeness . Tack it on to theever - growing list of graphene craziness . Some sort of graphene immortality ca n’t be that far off , right ? [ Zhejiang UniversityviaGizmag ]
