The geometric and electronic structures of a monolayer of C60 on a h-BN monolayer-covered Ni 111 surface are studied by first-principles calculations. The interaction between ions and electrons is described by the projector-augmented plane-wave method. The most stable structure of the h-BN/Ni 111 surface is found to be N on the top and B on the fcc site of Ni 111 . Upon adsorption, the structur...

This paper proposes a new panel model of cross-sectional dependence. The model has a number of potential structural interpretations that relate to economic phenomena such as herding in financial markets. On an econometric level, it provides a flexible approach of modelling interactions across panel units and can generate endogenous cross-sectional dependence that can resemble the dependence tha...

Disability and Multi-State Labour Force Choices with State Dependence I use a dynamic mixed multinomial logit model with unobserved heterogeneity to study the impact of work limiting disabilities on disaggregated labour choices. The first seven waves of the Household Income and Labour Dynamics in Australia survey are used to investigate this relationship. Findings point out to strong state depe...

Path dependence in occupations refers to the observed occupational distribution in a population or in a sub-population at a point in time that depends on changes that occurred years or centuries earlier. Path dependence in occupations can be the outcome of the cumulative concentration of certain productive activities in specific regions over time, it can emerge through the effect of parental in...

A water-soluble covalently linked C(60)-porphyrin compound-C(60)Por is reported to show enhanced DNA-cleaving activity. The highly enhanced DNA-cleaving activity is expected to be ascribed to the high water-solubility and affinity of C(60)Por to DNA, as well as to the accessibility to the charge-separated states C(60)˙(-)-Por˙(+) formed under radiation.

China and ASEAN have been maintaining a relationship both cooperative and competitive in the textile trade. Due to its labor intensive feature and high dependence on foreign trade , the textile trade has received much attention after the 2008 financial crisis. The customs data (classified by the HS code) from year 2006-2009 is employed to research the impact of the crisis on the trade pattern o...

We report a novel crystalline carbon-cage structure synthesized from laser-driven shock wave loading of a graphite-copper mixture to about 14+/-2 GPa and 1000 +/- 200 K. Quite unexpectedly, it can be structurally related to an extremely compressed three-dimensional C60 polymer with random displacement of C atoms around average positions equivalent to those of distorted C60 cages. Thus, the pres...

The C60 fullerenes are fascinating objects and even many years after their discovery the photo-physics of C60 is still full of surprises. With their well defined, highly symmetric structure the fullerenes are challenging model systems and examples of an interface between atoms or small molecules and the solid state. The 60 delocalized π electrons in the C60 fullerene give rise to interesting bu...

We present a force constants model for the vibrational modes in C60 dimer and polymer phases. The results of this model are used to calculate the nonresonant Raman spectra of infinitely long isolated C60 dimer and polymer peapod in the framework of bondpolarization theory by using the spectral moment’s method. The changes of the Raman spectrum in terms of the structure of the C60 molecules insi...

Organic thin-film solar cells with a conducting polymer (CP)/fullerene (C60) interpenetrating heterojunction structure, fabricated by spin-coating a CP onto a C60 deposit thin film, have been investigated and demonstrated to have high efficiency. The photovoltaic properties of solar cells with a structure of indium-tin-oxide/C60/ poly(3-hexylthiophene) (PAT6)/Au have been improved by the insert...
