Alterations and Contaminations in Ceramics Deposited in Underwater Environments: An Experimental Approach
(MDPI, 2021-07-15)Ancient ceramics recovered after a long burial period have probably undergone several alterations and contaminations, introducing a chemical variability, affecting the ceramic’s natural variability. That is, the chemical ... -
An electroactive and thermo-responsive material for the capture and release of cells
(Elsevier, 2021-06-05)Non-invasive collection of target cells is crucial for research in biology and medicine. In this work, we combine a thermo-responsive material, poly(N-isopropylacrylamide), with an electroactive material, poly(3,4-ethyle ... -
Application of a Biological Multilevel Response Approach in the Copepod Acartia Tonsa for Toxicity Testing of Three Oil Water Accommodated Fractions
(Elsevier, 2021-06-01)Abstract Copepods play a critical role in the marine food webs, being a food source for marine organisms. In this study, we investigated the toxic effects of Water Accommodated Fractions (WAFs) from three types of oil: ... -
Aspergillus fumigatus Fumagillin Contributes to Host Cell Damage
(MDPI, 2021-11-03)The activity of fumagillin, a mycotoxin produced by Aspergillus fumigatus, has not been studied in depth. In this study, we used a commercial fumagillin on cultures of two cell types (A549 pneumocytes and RAW 264.7 ... -
AZO Embedded IDEs for Monitoring Stimuli Responsive Materials
(Wiley, 2018-11)A combination of atomic layer deposition and photolithography is applied to fabricate interdigitated electrodes of aluminum-doped zinc oxide embedded in polyethylene terephthalate substrates. Various designs with different ... -
Biochemical and Metabolomic Changes after Electromagnetic Hyperthermia Exposure to Treat Colorectal Cancer Liver Implants in Rats
(MDPI, 2021-05-17)Background: Hyperthermia (HT) therapy still remains relatively unknown, in terms of both its biological and therapeutic effects. This work aims to analyze the effects of exposure to HT, such as that required in anti-tumor ... -
Characterization of the contamination fingerprint of wastewater treatment plant effluents in the Henares River Basin (central Spain) based on target and suspect screening analysis
(Elsevier, 2022-02-01)The interest in contaminants of emerging concern (CECs) has increased lately due to their continued emission and potential ecotoxicological hazards. Wastewater treatment plants (WWTPs) are generally not capable of eliminating ... -
