Hundreds of compounds have been detected in different environmental compartments, which may be natural or anthropogenic origin. In many cases, little is known about these compounds, thus there is not regulations for them, leading them be considered effective contaminants and so are called emerging. Among these compounds can be cited the biocides of...

To understand the stability of hydrous phases in mafic oceanic crust under deep subduction conditions, high-pressure and high-temperature experiments were conducted on two hydrous basalts using a Kawai-type multi-anvil apparatus at 17–26 GPa and 800–1200 °C. In contrast to previous studies on hydrous basalt that reported no hydrous phases in this p...
At the European Spallation Source (ESS), neutrons will be generated by spallation induced by a 2-GeV proton beam on a tungsten target. ESS will have a grid of 42 beamports available for a variety of neutron scattering experiments. Neutron moderators will provide thermal and cold neutrons to the instruments, allowing bispectral beam extraction where...
Stormwater carries pollutants that potentially cause negative environmental impacts to receiving water bodies, which can be quantified using life cycle impact assessment (LCIA). We compiled a list of 20 metals, almost 300 organic compounds, and nutrients potentially present in stormwater, and measured concentrations reported in literature. We calcu...
Exposure science, in its broadest sense, studies the interactions between stressors (chemical, biological, and physical agents) and receptors (e.g. humans and other living organisms, and non-living items like buildings), together with the associated pathways and processes potentially leading to negative effects on human health and the environment. ...
Objetivo/contexto: Se presenta una reflexión antropológica sobre lo que provocan los procesos de desertificación del lago Poopó, en Bolivia, particularmente para el grupo uru-qotzuñi (“gente del agua”), desde un enfoque que se propone como una antropología de la vida. Se analiza cómo las prácticas cotidianas y rituales permiten una correspondencia ...
The objective of the present work was to evaluate the water hyacinth (WH) as a substrate for the production of hydrolytic enzymes (cellulases and hemicellulases) of 100 strains of filamentous fungi under conditions of solid growth. Five fungal strains, identified as Trichoderma harzianum, Trichoderma atroviride, Penicillium griseofulvum, Penicilliu...

In this work, the surface mechanisms including reaction, adsorption and desorption steps during the ALD of Al2O3 from TMA and H2O on Si substrates are investigated. The analysis is performed using a surface chemistry model, coupled to a CFD model for a commercial reactor treating 20 cm Si wafers. [4] This model is used to feed a geometric model tha...
