Foreign Direct Investment and Exchange Rate Regimes
The paper uses a comprehensive data set with bilateral direct investment flows and establishes the influence of the de-facto exchange rate regime for FDI flows. We find a strong and significant effect from fixed rates on bilateral FDI flows in developed economies, but no significant effect for developing countries. There is thus no general and uniform impact of stable exchange rates on FDI. We provide several possible explanations for this difference.Foreign Direct Investment, Multinational Enterprises, Exchanges Rate Regimes

The influence of the layer sizes on the conversion regimes realizing at layered composite synthesis
The composite materials with different structure find a variety of applications. However, the peculiarities of the propagation of chemical reactions between structural elements during composite material synthesis are poorly studied. This paper suggests a model describing the conjugation of structure composite elements using a solid phase reaction at the ignition from a free surface. It was established that depending on the relation between layer sizes, various conversion regimes between inert materials are observed. The regimes differ in temperature values in the reaction zone, heterogeneities of temperature field and reaction zone thickness. Relation between thermophysical properties and thicknesses of layers can both promote reaction and retard it
In situ observation of stress relaxation in epitaxial graphene
Upon cooling, branched line defects develop in epitaxial graphene grown at
high temperature on Pt(111) and Ir(111). Using atomically resolved scanning
tunneling microscopy we demonstrate that these defects are wrinkles in the
graphene layer, i.e. stripes of partially delaminated graphene. With low energy
electron microscopy (LEEM) we investigate the wrinkling phenomenon in situ.
Upon temperature cycling we observe hysteresis in the appearance and
disappearance of the wrinkles. Simultaneously with wrinkle formation a change
in bright field imaging intensity of adjacent areas and a shift in the moire
spot positions for micro diffraction of such areas takes place. The stress
relieved by wrinkle formation results from the mismatch in thermal expansion
coefficients of graphene and the substrate. A simple one-dimensional model
taking into account the energies related to strain, delamination and bending of
graphene is in qualitative agreement with our observations.Comment: Supplementary information: S1: Photo electron emission microscopy and
LEEM measurements of rotational domains, STM data of a delaminated bulge
around a dislocation. S2: Movie with increasing brightness upon wrinkle

Graphene on Ir(111): Physisorption with chemical modulation
The nonlocal van der Waals density functional (vdW-DF) approach is applied to calculate the binding of graphene to Ir(111). The precise agreement of the calculated mean height h = 3.41 Å ; of the C atoms with their mean height h = (3.38 ± 0.04) Å ; as measured by the X-ray standing wave (XSW) technique provides a benchmark for the applicability of the non-local functional. We find bonding of graphene to Ir(111) to be due to the van der Waals interaction with an antibonding average contribution from chemical interaction. Despite its globally repulsive character, in certain areas of the large graphene moiré unit cell charge accumulation between Ir substrate and graphene C atoms is observed, signaling a weak covalent bond formation
