Scientists In China Predict Pentagonal Graphene
TechkNighT_1337 writes: Chinese scientists made calculations and predict that a new 2D allotrope of carbon based in a pentagonal form resembling a common pavement in the streets of Cairo can be synthesized. They call this new form penta-graphene. From the announcement in the Chemistry World, they say: "The team found that not only should a pentagon-containing version of graphene be fairly stable, it should also be stronger than conventional graphene and be able to withstand higher temperatures, up to 730C. It would also be a natural semiconductor, unlike conventional graphene, which is a highly efficient conductor and has to be chemically modified to turn it into a semiconductor."
Yes. Graphene does not "melt". it sublimates at very high temperatures. That's why graphite crucibles are used in foundries.
You know they changed it right because Pizza Hut paid them a pile of cash? Anyone who goes along with the change to Pizza Hut from Taco Bell is an asshole. It doesn't even make sense because some scenes still show the Taco Bell logo.
Your theory doesn't take in to consideration Pizza Hut and Taco Bell are part of the same company (was PepsiCo at the time of filming now Yum! Brands) and Pizza Hut and Taco Bell even have co-located in some stores (although there are other combinations like KFC/PizzaHut and KFC/TacoBell).
The commonly accepted rationale is that Taco Bell is mainly just a US brand and since PepsiCCo paid for the product placement originally, they wanted to substitute one of their well known international brands for the international release of the movie to get more advertising mileage out of the placement...
But PepsiCo probably had to pay for the change, and of course they did a crappy job of executing the change...
Right alongside heavier-than-air flight.
