Optoelectronic properties of phosphorene quantum dots functionalized with free base porphyrins
Electronic and optical properties of phosphorene quantum dots functionalized with an organic molecule, porphyrin, are investigated using density functional theory with two different van der Waals functionals. The electronic ... -
Optical properties of n-type asymmetric triple ?-doped quantum well under external fields
We present a theoretical investigation about the the influence of external electric, magnetic and non-resonant intense laser fields on intersubband-related second harmonics generation (SHG) and the nonlinear optical ... -
Magneto-optical properties of Fibonacci graphene superlattices
Abstract: We have studied the transition strength and magneto-optical absorption in Fibonacci graphene superlattices under the effects of perpendicularly applied magnetic field. It is shown that the former quantity present ... -
Assessing Colombia's policy of socio-economic stratification: An intra-city study of self-reported quality of life
This paper aims to analyse whether the Colombian government's classification of households into socio-economic strata accurately reflects the level of quality of life of households in Medellin. To this end, logit multilevel ... -
New insights on the influence of low frequency pulsed current on the characteristics of PEO coatings formed on AZ31B
In this work, anodic oxide layers on the surface of an AZ31 magnesium alloy were obtained by plasma electrolytic oxidation (PEO) process under low frequency pulsed current. For this, electrolytical solutions containing ... -
Investigation and evidence of context as elements of criminal policy for the prosecution of the organized crime [La investigación y la prueba de contexto como elementos de política criminal para la persecución del crimen organizado]
The problem addressed by the article is directly related to the reflection about what is the incidence of research and context evidence as elements of criminal policy to prosecute the organized crime. We drew as first ... -
