The coadsorption and interaction of molecular icosahedra with mercury
نویسندگان
چکیده
We have investigated the changes in the electronic structure of molecu larly adsorbed orthocarborane fi lms, as a function of Hg co-adsorption, using photoe mission. The interaction between Hg and molecular orthocarborane is weak and results in the formation of some small aggregates of Hg. This behavior is very different from alkali metals interaction with molecular carborane fi lms and the interaction of Hg with semiconducting boron carbide fi lms. Hg doping of semiconducting boron carbide may decrease the activation barrier for intrinsic carrier mobility, but does not signifi cantly increase the number of carriers.

Mercury and C2B10 Icosahedra Interaction
We contrast the interaction of mercury with adsorbed orthocarborane films and semiconducting (dehydrogenated) boron carbide. Photoemission spectra reveal small shifts in orthocarborane (C2B10H12) molecular orbital binding energies as well as the shift in mercury 5d5/2 shallow core level binding energies, suggesting only small interaction between mercury and the molecular film. Mercury does, how...
متن کاملCoadsorption of Dioxygen and Carbon Monoxide on a Mg(100) Surface
The activation of carbon monoxide by oxygen on Mg(100) surface has been investigated by X-ray photoelectron spectroscopy (XPS). Carbon monoxide is only weakly adsorbed (dispersion-type forces) on a magnesium surface. The XPS result has shown that the dissociation of carbon monoxide leading to the formation of a metastable surface carbonate species occurs through the participation of an oxyg...
متن کاملThe Effective Potential Function of the Liquid Mercury on the Metallic and Nonmetallic States by Using the Experimental Internal Pressure
The major reason for the prediction of thermodynamic properties of mercury lies in the fact that itsintermolecular interactions highly depend on temperature and density. Internal pressure is a good criterion toinvestigate the density dependence of the interatomic interactions. Because its physical base is a forcetending to close together the molecules that is intermolecular interactions, and as...
متن کاملStudy of the Interaction of Cinnamaldehyde with Alpha-lactalbumin: Spectroscopic and Molecular Docking Investigation
Cinnamaldehyde is an important compound of the cinnamon essential oil, and it is responsible for the most of the health benefits of cinnamon. Enriching foods such as milk with cinnamaldehyde can lead to greater utilization of cinnamaldehyde properties. In this study, we investigated the interaction of cinnamaldehyde with bovine alpha-lactalbumin. Analyzing the spectrum of alpha-lactalbumin in t...
متن کاملSelf-Assembly of Patchy Particles.
Molecular simulations are performed to study the self-assembly of particles with discrete, attractive interaction sites - "patches" - at prescribed locations on the particle surface. Chains, sheets, rings, icosahedra, square pyramids, tetrahedra, and twisted and staircase structures are obtained through suitable design of the surface pattern of patches. Our simulations predict that the spontane...
