CO OZNACZA SŁOWO GRAPHENE
Grafen
Graphene to czysty węgiel w postaci bardzo cienkiego, prawie przezroczystego arkusza, o grubości jednego atomu. Jest niezwykle silny z powodu bardzo małej wagi, a przy tym oferuje ciepło i energię elektryczną z dużą wydajnością. Choć naukowcy teoretyzowali graphene od dziesięcioleci, po raz pierwszy została ona wyprodukowana w laboratorium w 2004 roku. Ponieważ jest praktycznie dwuwymiarowa, oddziałuje dziwnie ze światłem i innymi materiałami. Naukowcy zidentyfikowali efekt tranzystora bipolarnego, balistyczny transport ładunków i duże oscylacje kwantowe. Technicznie, grafen jest krystalicznym allotopem węgla o właściwościach dwuwymiarowych. W przypadku grafenu, atomy węgla są gęsto zapakowane w regularnie spotykany wzór sproszkowanego kurczaka atomowego. Grafen można opisać jako grubą warstwę grafitu o grubości jednego atomu. Jest to podstawowy element strukturalny innych alotropów, w tym grafit, węgiel, nanorurki węglowe i fulereny. Można ją również uznać za niezmiernie dużą aromatyczną cząsteczkę, ograniczającą rodzinę płaskich policyklicznych węglowodorów aromatycznych. Badanie grafenu szybko się rozszerzyło, ponieważ substancja została po raz pierwszy wyizolowana w 2004 r.

CYTATY ZE SŁOWEM «GRAPHENE»
Słynne cytaty i zdania ze słowem
graphene.
A carbon nanotube is just a graphene sheet that's rolled up seamlessly, and this happens in nature; carbon nanotubes are found in mineral deposits around the planet.
The concept of graphene came along in 1947, but nobody paid much attention to it. I was fascinated because it had a linear E versus K while everything else that people were working on at that time had a quadratic dispersion relationship. I wondered why this was and what was so special about it. That was my fascination.
