What is the novel drying process? I can't proxy in to my uni on my phone so i cant read the full paper but the article doesnt seem to mention a new drying technique. Aerogels have been made using super critical CO2 for decades now (for example, as the space shuttle reentry tiles covering the entire spacecraft) and many interesting variants have been made using this technique including carbon aerogels which have a mind-boggling capacitance, on the order of 5 Farads per cubic centimeter.
I also believe gold/nanoparticle aerogels have been made before (difficult to find citation now), although this is the first time I've seen anyone use protein fibers.
- iokevins 11y agoThank you; it seems I may have misunderstood. From the article, "The method chosen, in which the gold particles are crystallised directly during manufacture of the aerogel protein structure (and not, for example, added to an existing scaffold) is new. The method's biggest advantage is that it makes it easy to obtain a homogeneous gold aerogel, perfectly mimicking gold alloys." The paragraph, on drying, preceded the above text. Hope this helps.
