Full-text available
Microplastics are pervasive pollutants that pose threats to the environment and human health. Detecting them reliably represents a crucial step toward finding solutions. While traditional techniques like vibrational and mass spectroscopies are time-consuming and have limitations in analysing polymers with pigment additives, surface plasmon resonanc...

In this work, we present a heat flow analysis for a conceptual design of an open cycle liquid nitrogen cryostat with application in Mössbauer spectroscopy. Initially, we made a study of the different configurations of Dewar type cryostats reported in the literature. These configurations are based on existing designs and the Mössbauer spectrometer r...

In this work we present the design and thermal modeling of a cold finger open cycle cryostat that operates with liquid nitrogen, intended to be implemented into the Mössbauer spectrometer available at the Universidad EAFIT of Medellín, Colombia, with the purpose of obtaining a low cost and good performance system for the acquisition of low temperat...
Article
The introduction of nosyl moieties onto the lower rim of the calix[4]arene skeleton led to the formation of compounds immobilised in cone conformations. Subsequent reduction of the nitro group and reaction with aryl isocyanates enabled the construction of new calixarene-based ligands for anion recognition. As proven by NMR and UV/vis titration expe...
Conference Paper
A discrete model for the Lcac Operon is solved using the SMT-solver Z3. Traditionally the Lac Operon is formulated in a continuous math model. This model is a system of ordinary differential equations. Here, it was considerated as a discrete model, based on a Boolean red. The biological problem of Lac Operon is enunciated as a problem of Boolean sa...
