Graphene Graphene Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands (zero bandgap material).<ref name="10.1002/adma.201502544 p.6519-6525"></ref> It is the basic structural element of many other allotropes of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes. Graphene has many uncommon properties. It is the strongest material ever tested, conducts heat and electricity efficiently, and is nearly transparent. Graphene shows a large and nonlinear diamagnetism, greater than that of graphite, and can be levitated by neodymium
Early 2000s recession late 2000s. Early 2000s recession The early 2000s recession was a decline in economic activity which mainly occurred in developed countries. The recession affected the European Union during 2000 and 2001 and the United States in 2002 and 2003. The UK, Canada and Australia avoided the recession, while Russia, a nation that did not experience prosperity during the 1990s, in fact began to recover from said situation. Japan's 1990s recession continued. This recession was predicted by economists, because the boom of the 1990s (accompanied by both low inflation and low unemployment) slowed in some parts of East Asia during the
