Editorial 

The Editor is very happy to announce the first issue of Eclética Química Journal of 

2020, which contains varied and interesting subjects for the readers. The first article combines the 

color parameters of digital images with artificial neural networks (ANN) to predict the bulk 

density in leguminous grains of different traits. The challenge of estimating physicochemical 

properties of dry grains includes variations in shape, texture, and size and similarity of grains 

colors to the naked eye. The study allowed to obtain a very good correlation between the reference 

values and values predicted by the ANN. In the sequence, the synthesis, characterization using 

different physicochemical techniques, and theoretical calculations on the optimized structures of 

the Ni(II) mixed-ligand complexes are presented and discussed. The Schiff bases are coordinated 

to the Ni(II) ion via the two deprotonated phenolic oxygen and azomethine nitrogen atoms. The 

presented complexes, according to biological studies, demonstrated to have antibacterial and 

antioxidant properties. Following, a satisfactory method for identification and quantification of a 

widely used medicinal plant, species Harpagophytum procumbens DC, is described using high-

performance liquid chromatography allows the quality control of commercial products. The 

importance of this medicinal plant is promptly recognized due to the anti-inflammatory properties, 

which are attributed to an iridoid glycoside. Afterwards, it is well known that the continuous 

research endeavors for the optimization of mineral resource utilization efforts, justified by the 

primacy of the mineral industry and the need to fulfill the demand of the global market. In this 

sense, mineral characterization may be the first step, which was here achieved by grain-size 

analysis of coarse and fine aggregates of verdete rock and the methodology used represents a 

contribution to the mineral characterization. This issue of EQJ is closed with the description of 

how to obtain of exact bound state energy spectrum of the Schrödinger equation with energy 

dependent molecular Kratzer potential, using asymptotic iteration method. Particularly, the 

influence of the energy-dependent Kratzer potential on some diatomic molecules is described. 

The Editor and his team thank all the authors for their effective contributions, and the 

reviewers for their excellent evaluation of the manuscripts, wishing everyone a prosperous year 

in 2020.
