Spin-polarized density functional theory has been used to study the effects of vacancy defects on the magnetic properties of graphene. Structural optimization shows that introducing a carbon vacancy cluster into a graphene sheet changes the spatial distribution of the neighbor atoms,...

We develop an input–output methodology to estimate how Chinese exports affected the country's total domestic value added (DVA) and employment in the years 2002 and 2007. For every US$1000 dollar of Chinese exports in 2007 (2002), DVA and employment are estimated to be US$591 (US$466) and 0.096...
