The development of novel advanced nanomaterials (NMs) with outstanding characteristics for their use in distinct applications needs to be accompanied by the generation of knowledge on their potential toxicological impact, in particular, that derived from different occupational risk exposure routes, such as inhalation, ingestion, and skin contact. T...

Five benches of used vegetable oils were prepared by deep frying of commercial edible vegetable oil. Raman analyses of original and waste samples revealed few and small differences between samples. Nevertheless, statistical multivariate analysis, in particular unsupervised principal component analysis (PCA) followed by supervised partial least squa...

Thermal polymerization of glycine, the simplest amino acid bearing only one alfa carbon atom, is not an efficient process in mild conditions. Hydrothermal processing of glycine produces only small peptides, up to 4 units on average, with only a fraction of glycine that reacts. In the present work, we have used boric acid as a catalyst to promote th...

Due to the ever-increasing worldwide interest in the exploitation of waste vegetable oils, the development of analytical tools able to detect their adulteration with edible oils, is considered a priority for the scientific and industrial community. In this work, edible and waste vegetable oils have been analysed by Fourier Transform-InfraRed (FT-IR...

Fabrication of hydrophobic thin films from a liquid phase is a hot topic with critical technological issues. Interest in the production of hydrophobic surfaces is growing steadily due to their wide applications in several industrial fields. Thin films from liquid phases can be deposited on different types of surfaces using a wide variety of techniq...

Carbon nanotubes (CNTs) have attracted the attention of academy and industry due to their potential applications, being currently produced and commercialized at a mass scale, but their possible impact on different biological systems remains unclear. In the present work, an assessment to understand the toxicity of commercial pristine multi-walled ca...

In this work, piezoceramics of the lead‐free composition K0.5Na0.5NbO3 with an increasing amount of MgNb2O6 (0, 0.5, 1, 2 wt.%) were prepared through conventional solid‐state synthesis and sintered in air atmosphere at 1100 °C. The effect of magnesium niobate addition on structure, microstructure and piezoelectric properties was evaluated. The cera...
