Structural and electronic properties of lead sulfide quantum dots from screened hybrid density functional calculations including spin-orbit coupling effects
(Springer Verlag, 2017)
We present in this work density functional theory calculations of the structural and electronic properties of (PbS)n nanoparticles with n=4-32. Particular care has been taken on the correct description of their electronic ...

Host-guest interactions between cyclodextrins and surfactants with functional groups at the end of the hydrophobic tail
(Elsevier, 2017)
The aim of this work was to investigate the influence of the incorporation of substituents at the end of the hydrophobic tail on the binding of cationic surfactants to α-, β-, and -cyclodextrins. The equilibrium binding ...

Critical Role of Oxygen in Silver-Catalyzed Glaser-Hay Coupling on Ag(100) under Vacuum and in Solution on Ag Particles
(American Chemical Society, 2017)
The essential role of oxygen in enabling heterogeneously catalyzed Glaser-Hay coupling of phenylacetylene on Ag(100) was elucidated by STM, laboratory and synchrotron photoemission, and DFT calculations. In the absence of ...

First Principles Study of Nickel Complex with 1,3-dithiole-2-thione-4,5-dithiolate Ligands as Model Photosensitizers
(Springer Verlag, 2017)
Dye-sensitized solar cells (DSSCs) have become in one important and promising technology in the photovoltaic field. The ability for a sensitizer to harvest light photons and inject the excited electrons into a photoanode, ...

Effects of the capping ligands, linkers and oxide surface in the electron injection mechanism of copper sulfide Quantum Dots sensitized solar cells
(Royal Society of Chemistry, 2017)
Because of the different components that constitute a quantum dots solar cells, QDSCs, and the difficulty of experimentally isolate the effect of each of them on the adsorption spectra of the system, we have modeled different ...

Molecular dynamics simulations of the role of salinity and temperature on the hydrocarbon/water interfacial tension
(Springer Verlag, 2017)
Interfacial tension of some hydrocarbon/water systems, including a mixture of aliphatic and aromatic hydrocarbons, has been estimated on the basis of molecular dynamics simulations. The dependence of the interfacial ...
