Oinez Basoa: using school-managed afforested land for soil education in Navarre, Spain
El estudio del suelo en la educación secundaria es un tema de debate ya que, a pesar de la creciente preocupación por el suelo en las ciencias ambientales, sigue siendo poco considerado en los planes de estudio y programas ... -
Olive industry liquid waste from trash to metal adsorbent for wastewater purifcation
The development of biobased polymeric materials for wastewater purification has become a demand due to the growing need for water free of hazardous metal ions for safe purposes. The organic components of the OLLW including ... -
One-pot synthesis of green-emitting nitrogen-doped carbon dots from xylose
Carbon dots (CDs) are interesting carbon nanomaterials that exhibit great photoluminescent features, low cytotoxicity, and excellent water stability and solubility. For these reasons, many fields are starting to integrate ... -
Operation strategies guideline for packed bed thermal energy storage systems
Packed bed thermal energy storage (TES) systems have been identified in the last years as one of the most promising TES alternatives in terms of thermal efficiency and economic viability. The relative simplicity of this ... -
Optimization of the pentachlorophenol adsorption by organo-clays based on response surface methodology
The aim of this study is to optimize the adsorption of pentachlorophenol (PCP) using an organo-clay under the response surface methodology. The adsorbent was selected from a montmorillonite exchanged by various cations, ... -
Optimizing the removal of nitrate by adsorption onto activated carbon using response surface methodology based on the central composite design
This study sheds light on the adsorption process for the removal of nitrate ions from synthetic aqueous solutions. This contaminant pose a potential risk to the environment and can cause health effects including cancers ... -
Organic carbon storage and dynamics as affected by the adoption of irrigation in a cultivated calcareous mediterranean soil
Irrigation is in the spotlight of land-use planning in semi-arid and sub-humid regions. It can be a promising practice to promote soil organic C storage (SOC), although it may also involve an increase in soil GHG emissions. ... -
Organocatalytic Michael addition of unactivated a-branched nitroalkanes to afford optically active tertiary nitrocompounds
The direct, asymmetric conjugate addition of unactivated ¿-branched nitroalkanes is developed based on the combined use of chiral amine/ureidoaminal bifunctional catalysts and a tunable acrylate template to provide tertiary ... -
Outstanding role of the magnetic entropy in arrested austenite in an ordered Ni45Mn36.7In13.3Co5 metamagnetic shape memory alloy
The relevance of the entropy and in particular the outstanding role of the magnetic contribution is analyzed in a non-equilibrium arrested austenite phase in a Ni 45 Mn 36.7 In 13.3 Co 5 metamagnetic shape memory alloy. ... -
Phenolic composition of artichoke waste and its antioxidant capacity on differentiated Caco-2 cells
Artichoke waste represents a huge amount of discarded material. This study presents the by‐products (bracts, exterior leaves, and stalks) of the 'Blanca de Tudela' artichoke variety as a potential source of phenolic compounds ... -
Phenolic composition of grape stems from different Spanish varieties and vintages
Grape stems are a by‐product from the wine industry that has been underused to date despite having great potential for the agro‐food and cosmetic industries. The aim of the present work was to characterize grape stem ... -
Phenyl siloxane hybrid xerogels: structure and porous texture
The aim of this research is to investigate the effect of phenyltriethoxysilane (PhTEOS) and tetraethoxysilane (TEOS) molar ratios as silicon precursors on the structure and porous texture of xerogels. We have prepared ... -
Photovoltaic technology as a tool for ecosystem recovery: a case study for the Mar Menor coastal lagoon
A wide range of environmental impacts have been triggered worldwide by intensive agrarian production designed to maximize crop yields. The ecological crisis in the Mar Menor, Europe's largest salt-water lagoon, is an example ... -
Physiological, hormonal and metabolic responses of two alfalfa cultivars with contrasting responses to drought
Alfalfa (Medicago sativa L.) is frequently constrained by environmental conditions such as drought. Within this context, it is crucial to identify the physiological and metabolic traits conferring a better performance under ... -
Pinus sylvestris L. and Fagus sylvatica L. effects on soil and root properties and their interactions in a mixed forest on the Southwestern Pyrenees
Tree species alter soil properties, potentially modifying forest nutrients cycling. In the current management context in which mixed species forests are favoured over monocultures due to their biodiversity and productivity-related ... -
A plant gene encoding one-heme and two-heme hemoglobins with extreme reactivities toward diatomic gases and nitrite
In plants, symbiotic hemoglobins act as carriers and buffers of O2 in nodules, whereas nonsymbiotic hemoglobins or phytoglobins (Glbs) are ubiquitous in tissues and may perform multiple, but still poorly defined, functions ... -
