KICKER: WHEN BUILDING A SUPERCAPACITOR BEARS FRUIT
NEIL/ANCHOR: Our final story for the week asks: Are you hungry for a
new kind of supercapacitor? Wrap your tastebuds around this one from
Australia, which John Williams, VK4JJW, is serving to you, right now.
JOHN: What are hackers cooking up on their workbench lately? Well, at
the University of Sydney, it looks like jackfruit, and durian fruit
are what's on the menu. Researchers on this Australian campus found
they were able to use biomass from waste scraps of the two fruits to
create electrodes for a supercapacitor which, according to one published
report, doesn't let out any characteristic stench while in normal use.
The fruit aerogels were seen as having a large surface area and porous
structures, and the durian fruit in particular, was a top performer.
The fruit also had the winning combination of pyridinic and graphitis
nitrogen. Researchers say electrodes based on these aerogels outperform
standard carbon materials for energy storage.
The website Hackaday writes that clever tinkerers can replicate the
researchers' process in their own garages - provided of course, they
are adept at handling vinylidene fluoride, and other chemicals, and have
a vacuum oven, and a furnace, with nitrogen on hand.
Oh, and don't forget a stinky ripe durian or two. It might be the only
way to get your ultracapacitor project to truly bear fruit.
For Amateur Radio Newsline, I'm John Williams, VK4JJW.
