A new form of carbon, schwartzites, has been created

> Once inside, the carbon assembles into a graphene-like sheet that lines the walls of the zeolite pores. In doing so, the surface stretches and bends negatively.

I understand the negative curvature part, but the article fails to elaborate on why that’s an important or valuable property for a material to have. Can anyone explain a bit further?

Am I correct that it looks like a 3D lattice made of units like this?

"schwarzites", not "schwartzites", which the article mistakenly prints 4 times, plus the HN submission

How do they know that the structure has only negative curvature and not regions with positive curvature? (like a bunch of soap bubbles that have coalesced)The structure in the paper labeled ztc-RWY certainly looks like it is ONLY positively curved.

I am allowed to read articles at work, it is tangentially part of my job, but independent.co.uk just put me in an awkward situation, and not for the first time.

My boss walked by and made a joke about what I was reading. The physics of carbon is a perfect valid thing for me to read, but what caught his eye was the plethora of sidebar/sponsored content on independent.co.uk. Does every add have to involve sexy models? I've got a blonde schoolgirl pushing something about investments, a redhead with something to tell me about kindles, and a athlete in bathing suit pushing some other clickbait. Sure, this is a work computer and I'm sure the advertising spies know I'm male, but I don't want this crap on my screen at home either.

My mistake: I just tried to highlight one of the sponsored content headlines ... which was actually part of the underlying pic. So I just 'clicked' the redhead with the kindle. My bad. I guess I'll need to cover my screen every time I want to read about graphite.

Cue the "Spaceballs" references.
