Adsorption recovery of Ag(I) and Au(III) from an electronics industry wastewater on a clay mineral composite
The aim of this work is to investigate the ability of an adsorbent of a clay mineral composite to remove and recover gold and silver ions from wastewater. The composite was prepared by mixing phosphogypsum (PG), obtained ... -
An aerated axenic hydroponic system for the application of root treatments: exogenous pyruvate as a practical case
Background: Hydroponic systems are a convenient platform for plant cultivation when treatments are applied to the roots because they provide precise control of the composition of the growth medium, ensuring the availability ... -
Application of anti-transpirants temporarily alleviates the inhibition of symbiotic nitrogen fixation in drought-stressed pea plants
Stomatal closure is one of the first plant responses under a water deficit situation. This leads to a decline in transpiration but also in the plant photosynthetic activity. Legume plants grown under symbiosis with rhizobium ... -
Archaeometric study of Roman tesserae from Salamanca (Spain). Archaeology and geochemical analysis
In this study an analysis was made of 37 samples of tesserae of different shades and colours from Roman archaeological sites in the province of Salamanca (Spain), where pavements of opus tessellatum have been located. The ... -
Assessing the reliability of current simulation of thermoelectric heat pumps for nearly zero energy buildings: expected deviations and general guidelines
This paper makes evident that a rigorous review of simulation methods for thermoelectric heat pumps in nearly-zero energy buildings is needed, as incoherent results during verification and validation of simulation models ... -
Biodiesel production from heterogeneous catalysts based K2CO3 supported on extruded Γ-Al2O3
Catalytic biodiesel production from sunflower oil and ethanol using K2CO3/γ-Al2O3 in different configurations has been studied. To prepare the catalysts, boehmite was extruded with the aid of a binder and different percentages ... -
Biodiesel synthesis using a novel monolithic catalyst with magnetic properties (K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3) by ethanolic route
(Elsevier, 2020) Artículo / ArtikuluaA novel magnetic monolithic catalyst based on K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3 was developed seeking to convert efficiently soybean oil and bioethanol to ethanolic biodiesel and glycerol. The magnetic monolithic was attained ... -
Calculadora de sostenibilidad FIRST-Heat Navarra: generando energía sostenible al reducir el riesgo de incendios forestales en comunidades rurales
El cambio climático, la expansión urbanística o el aumento del uso recreativo en zonas forestales están aumentando la probabilidad de ocurrencia de incendios forestales. Las comunidades rurales pueden afrontar la oportunidad ... -
Catalytic performance of bulk and Al₂O₃-supported molybdenum oxide for the production of biodiesel from oil with high free fatty acids content
Non-edible vegetable oils are characterized by high contents of free fatty acids (FFAs) that prevent from using the conventional basic catalysts for the production of biodiesel. In this work, solid acid catalysts are used ... -
CIELAB color paths during meat shelf life
Meat color evolution from freshly cut to beyond shelf life, up to 40% of metmyoglobin, has been theoretically modeled using the Kubelka-Munk theory and a set of measured reference reflectance spectra of deoxymyoglobin, ... -
Coarse woody debris' invertebrate community is affected directly by canopy type and indirectly by thinning in mixed scots pine-European beech forests
Research Highlights: Thinning and tree species alter the forest floor microclimate by modifying canopy cover, radiation, wind, and humidity. Thus, forest management can directly influence the edaphic mesofauna responsible ... -
A combination of a vibrational electromagnetic energy harvester and a giant magnetoimpedance (GMI) sensor
An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric ... -
A combination of apple vinegar drink with Bacillus coagulans ameliorates high fat diet-induced body weight gain, insulin resistance and hepatic steatosis
Obesity is a worldwide epidemic characterized by excessive fat accumulation, associated with multiple comorbidities and complications. Emerging evidence points to gut microbiome as a driving force in the pathogenesis of ... -
A combination of Rosa canina extracts and gold complex favors apoptosis of Caco-2 cells by increasing oxidative stress and mitochondrial dysfunction
Given the alarming increase in colorectal cancer (CRC) worldwide, novel therapies are urgently needed. Plant-derived extracts have gained considerable interest in the last years due to their strong anticancer effect mediated ... -
Comparative removal of emerging contaminants from aqueous solution by adsorption on an activated carbon
Batch sorption experiments were performed to study the adsorption of six emerging pollutants from aqueous solutions using a commercial granular activated carbon as adsorbent. Caffeine, clofibric acid, diclofenac, gallic ... -
Development of digital competence in secondary education teachers' training
Digital competence is one of the eight key competences for life-long learning developed by the European Commission, and is a requisite for personal fulfilment and development, active citizenship, social inclusion, and ... -

Direct analysis of aluminum alloys by CSigma laser-induced breakdown spectroscopy
We report the application of CSigma laser-induced breakdown spectroscopy (Cσ-LIBS) to quantitative analysis of aluminum alloys without sample preparation. Cσ-LIBS simplifies strongly the conventional calibration procedure ... -
Drought tolerance response of high-yielding soybean varieties to mild drought: physiological and photochemical adjustments
Soybean is a crop of agronomic importance that requires adequate watering during its growth to achieve high production. In this study, we determined physiological, photochemical and metabolic differences in five soybean ... -
