Enhanced terahertz sensitivity for glucose detection with a hydrogel platform embedded with Au nanoparticles
We presented a strategy for enhancing the sensitivity of terahertz glucose sensing with a hydrogel platform pre-embedded with Au nanoparticles. Physiological-level glucose solutions ranging from 0 to 0.8 mg/mL were measured ...
Photosynthesis, resource acquisition and growth responses of two biomass crops subjected to water stress
This study compares photosynthesis, growth, 13C and 15N labelling patterns of two biomass crops (Arundo donax L. and Panicum virgatum L.) grown under water stress in greenhouse conditions. Plants were exposed to three water ...
I Jornada de Joves Investigadors de l'IdRA
La I Jornada de Joves investigadors és una primera iniciativa per fer aflorar i donar visibilitat a la recerca dels més joves, planter de les futures generacions de l'IdRA. La pròpia tasca organitzativa i científica de na ...
Nitrate removal by combining chemical and biostimulation approaches using micro-zero valent iron and lactic acid
The occurrence of nitrate is the most significant type of pollution affecting groundwater globally, being a major contributor to the poor condition of water bodies. This pollution is related to livestock-agricultural and ...
Geology, geochemistry and mineralogy of the Loma de Hierro Ni-laterite deposit, Venezuela
Ni-laterite deposits host over 60% of the word land-based Ni resources (McRae, 2018). They formed from the weathering of Mg-rich ultramafic rocks exposed to the surface under favorable topography and climatic conditions. ...
VIII Jornada de Joves Investigadors de l’IdRA
L’aigua ens connecta a tots amb tot. És present en cada racó de la nostra vida i alhora és un dels recursos més fràgils que tenim. Aquest any, més que mai, hem sentit la seva absència i la seva força: la sequera persistent ...
Evaluation of a virus concentration method based on ultrafiltration and wet foam elution for studying viruses from large-volume water samples
Assessing the presence of viruses in large-volume samples involves cumbersome methods that require specialized training and laboratory equipment. In this study, a large volume concentration (LVC) method, based on dead-end ...
Analysing the contribution of intermittent rivers to beta diversity can improve freshwater conservation in Mediterranean rivers
In Mediterranean climate regions, intermittent rivers (IRs) harbor highly dynamic communities with species and trait composition changing over time and space. Simultaneously considering multiple biodiversity facets and a ...
Evaluation of synthesis conditions for plastic scintillation foils used to measure alpha- and beta-emitting radionuclides
Plastic scintillation foils of polystyrene and polycarbonate with a thickness between 45 and 200 μm, have been produced using the solvent evaporation method. PSfoils presented a reproducible thickness (10-20%). PSfoils ...
Moradebrichthys vilasecae gen. et sp. nov., a new perleidid (Actinopterygii: Osteichthyes) from the Middle Triassic of Catalonia (NE Iberian Peninsula)
A new actinopterygian, Moradebrichthys vilasecae gen. et sp. nov., from the Middle Triassic (Late Ladinian) of Móra d'Ebre-Camposines (Catalonia, NE Iberian Peninsula) is erected on the basis of several, almost complete, ...
La Transformación del mundo agrario en un territorio turístico de montaña. Las comarcas de Alta Ribagorça, Aran y Pallars Sobirà.
[spa] En el Pirineo catalán, partiendo de una economía tradicional de base ganadera y forestal, el territorio se ha especializado desde la perspectiva económica en el sector terciario; hecho que también ha supuesto importantes ...
Significado científico y valor patrimonial del glaciar histórico del Corral del Veleta (Sierra Nevada). Scientific value and natural heritage of the historical glacier of the Veleta cirque (Sierra Nevada)
Resumen. El reducto glaciar del Corral del Veleta fue el más importante de los desarrollados en Sierra Nevada durante la Pequeña Edad del Hielo (PEH) permaneciendo visible hasta mediados del siglo xx. En la actualidad, ...
Multivariate standard addition for the analysis of overlapping voltammetric signals in the presence of matrix effects: Application to the simultaneous determination of hydroquinone and catechol
A multivariate version of the classical univariate standard addition method is tested as a proof of concept for the voltammetric analysis of complex samples generating overlapped signals in the presence of significant ...
Considerations on the use of spectroelectrochemistry in reflection mode for quantitative analysis: Study of the Fe(III)/Fe(II) - orthophenanthroline system
Theoretical and experimental considerations are made about possible analytical applications of spectroelectrochemistry (SEC) in reflection mode using screen-printed electrodes. The system Fe(III)/Fe(II) - orthophenanthroline ...
Determination of HPLC-UV fingerprints of Spanish paprika (Capsicum annuum L.) for its classification by linear discriminant analysis
The development of a simple HPLC-UV method towards the evaluation of Spanish paprika' phenolic profile and their discrimination based on the former is reported herein. The approach is based on C18 reversed-phase chromatography ...
