Bulk production of a new form of sp(2) carbon: crystalline graphene nanoribbons.

Abstract: We report the use of chemical vapor deposition (CVD) for the bulk production (grams per day) of long, thin, and highly crystalline graphene ribbons (<20−30 μm in length) exhibiting widths of 20−300 nm and small thicknesses (2−40 layers). These layers usually exhibit perfect ABAB... stacking as in graphite crystals. The structure of the ribbons has been carefully characterized by several techniques and the electronic transport and gas adsorption properties have been measured. With this material available to researchers, it should be possible to develop new applications and physicochemical phenomena associated with layered graphene.

Fiscal Policy, Profits, and Investment

Abstract: This paper evaluates the effects of fiscal policy on investment using a panel of OECD countries. In particular, we investigate how different types of fiscal policy affect profits and , as a result, investment. We find a sizable negative effect of public spending -- and in particular of its public wage component -- on business investment. This result is consistent with models in which government employment creates wage pressure for the private sector. Various types of taxes also have negative effects on profits, but, interestingly, the effects of government spending on investment are larger than the effect of taxes. Our results have important implications for the so called 'Non-Keynesian' (i.e. expansionary) effects of fiscal adjustments.
