Lotteries are introduced into Cavalcanti and Erosa (2008) [2], a version of Trejos and Wright (1995) [4] with aggregate shocks. Lotteries improve welfare and eliminate the two notable features of the optimum with deterministic trades: over-production and history-dependence. Moreover, the optimum can be supported by buyer take-it-or-leave-it offers. © 2011 Elsevier Inc. All rights reserved. JEL ...

We consider transport through a single N@C60 molecule, weakly coupled to metallic leads. Employing a density-matrix formalism we derive rate equations for the occupation probabilities of many-particle states of the molecule. We calculate the current-voltage characteristics and the differential conductance for N@C60 in a break junction. Our results reveal Coulomb-blockade behavior as well as a f...

Hybrid nanostructured materials can exhibit different properties than their constituent components, and can enable decoupled engineering of energy conversion and transport functions. Novel means of building hybrid assemblies of crystalline C60 and carbon nanotubes (CNTs) are presented, wherein aligned CNT films direct the crystallization and orientation of C60 rods from solution. In these hybri...

Organic semiconductor/ferromagnetic bilayer thin films can exhibit novel properties due to the formation of spinterface at interface. Buckminsterfullerene (C60) has been shown ferromagnetism interface when it is placed next a ferromagnet (FM) such as Fe or Co. Formation occurs orbital hybridization and spin-polarized charge transfer In this work, we have demonstrated that one enhance magnetic a...

Solution-processed organic field effect transistors (OFETs), which are amenable to facile large-area processing methods, have generated significant interest as key elements for use in all-organic electronic applications aimed at realizing low-cost, lightweight, and flexible devices. The low performance levels of n-type solution-processed bottom-contact OFETs unfortunately continue to pose a bar...

sensitivity analysis with respect to the functional forms provides estimates of the uncertainties involved in choosing a specific functional structure. this is vital in cge modeling where it is conventional to take elasticities from other studies. in the present study, the robustness of model results with respect to the functional form is checked. in one scenario, the production function is rep...

We have assembled molecular arrays of C60 inside double-walled carbon nanotubes (DWNTs) with internal diameters of 11-26 A and directly observed the existence of different crystalline phases of C60 previously predicted theoretically. The structure of the encapsulated C60 crystal is defined by the internal diameter of the DWNT, as the molecules adjust their packing arrangement in order to maximi...

Fullerene (C60) films were prepared on Si, ITO, and Cu substrates by the physical vapor deposition (PVD) method. It was observed that the morphology and structure of fullerene films strongly depend on the substrates. Along with the interactions between fullerenes and substrates increasing from ITO, Si to Cu substrate, C60 forms small polycrystalline grains, large polycrystalline grains and full...

A new series of exTTF hosts has been synthesized for supramolecular binding study of fullerenes C60 and C70. Binding constants for C60 in chlorobenzene, toluene, toluene-CH2Cl2 and CS2 have been calculated for different hosts and a direct structure-affinity relationship has been established. As predicted, receptors with two exTTF moieties (1, 3 and 4) have demonstrated higher binding abilities ...

C60 nanorods, about 200 nm in diameter and several micrometers in length and with a rectangular cross section, have been synthesized by a simple solution-growth method. Raman spectroscopy and TEM indicate that the C60 nanorods have a fcc crystalline structure similar to that of pristine C60. Nanorods were polymerized at high temperature and high pressure below 2 GPa. Two different polymeric str...
