Nature and strength of weak O···O interactions in nitryl halide dimers
(2022-12-14)The use of real space functions and molecular graphs has pushed some chemists to wonder: Are interactions between negatively charged oxygen atoms possible? In this contribution we analyze whether there is a real interaction ... -
Obtención de pirodextrinas de sorgo para usos en alimentos
(2022-10-06)Las pirodextrinas son un producto de la piroconversión del almidón que resultan resistentes a la hidrólisis por las enzimas digestivas. Se obtienen mediante un tratamiento ácido-térmico, resultando en un producto con ... -
Production of wort from high tannin content sorghum through a whole grain extrusion process
(2021-11-21)En el uso de granos alternativos para elaborar bebidas fermentadas para personas celíacas, como el sorgo, puede partirse de granos malteados o sin maltear. Cuando la materia prima es el sorgo sin maltear, se debe recurrir ... -
Rosetas de melamina sustituidas : interrelación entre la energía de dimerización y los efectos de sustitución
(2021-11-18)La melamina (M) es una triamino triazina ampliamente usada en la química supramolecular, dado que es capaz de formar hexámeros cíclicos mediante puentes de hidrógeno. Estas rosetas pueden ser adsorbidas sobre diferentes ... -
The impact of pirodextrin addition to improve physicochemical parameters of sorghum beer
(2021-06-28)The traditional sorghum beer brewed by African communities differs from the traditional beer obtained from barley, mainly in the absence of hops and in a higher acidity level. People diagnosed with celiac disease find it ... -
Understanding the chloride affinity of barbiturates for anion receptor design
(2021-02-25)Due to their potential binding sites, barbituric acid (BA) and its derivatives have been used in metal coordination chemistry. Yet their abilities to recognize anions remain unexplored. In this work, we were able to identify ... -
Understanding the influence of alkali cations and halogen anions on the cooperativity of cyclic hydrogen-bonded rosettes in supramolecular stacks
(2022-11-07)Hydrogen-bonded supramolecular systems are known to obtain extra stabilization from the complexation with ions, like guanine quadruplex (GQ). They experience strong hydrogen bonds due to cooperative effects. To gain deeper ...
