In the field of transient tolerance tests, few studies have been conducted on gate voltage spikes of GaN HEMT components. A parametric generation of such overvoltage either implies precise and tedious hardware gate circuitry design, or require some simplification of the waveform making it less representative of actual and practical cases. Such test...
Nowadays, the exploitation of biopolymers in the industrial sector has become a trend. Chitosan is considered one of the most investigated biopolymers due to its abundance and antibacterial, antifungal, and antibiofilm activities. In this work, chitosan was chemically extracted from shrimp shells. Solutions of HCl 1 M, NaOH 4 M, and NaOH 15 M were ...
Bauxite residues (BRs) are highly alkaline wastes generated during alumina production from bauxite ore. Billions of tons have been accumulating worldwide for more than 100 years, they are stored in various forms, and pose environmental and societal issues. At the same time, BRs are promising secondary sources for the production of critical metals i...

Toxoplasma gondii is a zoonotic protozoan that can parasitize nucleated cells of all warm-blooded animals, and seriously harm human and livestock. Toltrazuril (TOL) has insecticidal activity against parasites of the phylum Apicomplexan at multiple development stages, but the clinical application is limited by its poor water solubility. To improve t...
[ES] Para la caracterización de materiales piezoeléctricos, el método de resonancias, descrito por el IEEE(Institute of Electrical and Electronics Engineers), es un método no destructiva dinámica para la obtención de las constantes del material. Cuatro cerámicas piezoeléctricas fueron elegidas y medidas utilizando un analizador de impedancias, obte...
