Electronic structure and optical properties of triangular GaAs/AlGaAs quantum dots: Exciton and impurity states
Electronic structure and optical properties in equilateral triangular GaAs/Al0.3Ga0.7As quantum dots are studied extensively. The effects of donor and acceptor impurity atoms positioned in the orthocenter of the triangle, ...
Structure and bonding in WCn (n = 2–5) clusters
Stochastic explorations of the configurational spaces for WC n (n = 2–5) clusters lead to densely populated spin states at each molecularity. We found 8, 16, 42, and 68 well-defined minima for n = 2, 3, 4, 5, respectively, ...

Organizational software processes improvement offers a key opportunity for organizations to be more efficient and effective. However, in most cases software process improvement initiatives in organizations become a path ...
Gas-Phase Elimination Reaction of Ethyl (5-cyanomethyl-1,3,4-thiadiazol-2-yl)carbamate: A Computational Study
The gas‐phase elimination reaction of ethyl (5‐cyanomethyl‐1,3,4‐thiadiazol‐2‐yl)carbamate has been studied computationally at the MP2/6–31++G(2d,p) level of theory. The values of the activation parameters and rate constants ...
Remote sensing analysis of belmira's paramo vegeatation with landsat imagery [Teledetección de la vegetación del páramo de belmira con imágenes landsat]
The purpose of this study is to distinguish the forest of Belmira's Páramo from other land cover classes. Three LANDSAT images are available (1996, 2002 and 2003). Remote sensing analysis of the vegetation coverage includes ...
Study of the formation of alkaline electroless Ni-P coating on magnesium and AZ31B magnesium alloy
In this work, alkaline electroless Ni-P coatings were directly formed on commercial purity magnesium and AZ31B magnesium alloy substrates using a process that avoided the use of Cr(VI) compounds. The study focused on two ...
Excitation-dependent fluorescence from atomic/molecular layer deposited sodium-uracil thin films
Atomic/molecular layer deposition (ALD/MLD) offers unique possibilities in the fabrication of inorganic-organic thin films with novel functionalities. Especially, incorporating nucleobases in the thin-film structures could ...
Ab initio study of hydrogen chemisorption in nitrogen-doped carbon nanotubes
The electronic structure of single walled nitrogen-doped carbon nanotubes is calculated by first principles using density functional theory within the supercell approach with periodic boundary conditions. The effect of the ...
