Vera Baquero, Fernando Leonardo; Sierra Alonso, Isabel; Morante Zarcero, Sonia; Casado Navas, Natalia; Gañán Aceituno, Judith, 2026, "Effect of fermentation and baking on tropane, opium, and pyrrolizidine alkaloids during the homemade preparation of gluten-free bread with poppy seeds and aromatic herbs", https://doi.org/10.21950/6DSCRN, e-cienciaDatos, V1
This study investigated the effect of bread-making on the fate of 29 different tropane (TAs), opium (OAs), and pyrrolizidine (PAs) alkaloids. The variation in the content of these compounds was determined during the fermentation stage and subsequently after baking. Doughs were prepared with ingredients that were likely to be naturally contaminated... |

MORENO DE LA CALLE, Alvaro; MEGIA, Pedro J.; Calles, Jose A; CARRERO, ALICIA; Vizcaíno, Arturo, 2027, "Shaped mesostructured Ni/CeO2 as active catalysts in hydrogen production from acetic acid oxidative steam reforming", https://doi.org/10.21950/DTGWBT, e-cienciaDatos, V2
Oxidative steam reforming (OSR) of acetic acid was carried out using shaped catalysts prepared by combining Ni supported on mesostructured ceria with various clays (kaolinite, sepiolite, attapulgite, and bentonite). Bentonite or attapulgite extrudates calcined with 1°C/min heating rate demonstrated better mechanical resistance. Higher acetic acid c... |

Pilar, Garcia Diaz; Espinosa Esteban, María del Mar; Martínez Rojas, Juan Antonio, 2026, "Acoustic Cavity Spectra for Classifying Salt Concentrations", https://doi.org/10.21950/Z0BEI4, e-cienciaDatos, V1
We present and validate an audible-band, resonant-cavity acoustic system that operates both as a sensor and as an automatic classifier for the nondestructive analysis of aqueous solutions, enabling the discrimination of solute concentrations using small liquid volumes. Frequency spectra computed from impact recordings on a glass resonator were used... |
