Preparation of selenium-based drug-modified polymeric ligand-functionalised Fe3O4 nanoparticles as multimodal drug carrier and magnetic hyperthermia inductor
In recent years, much effort has been invested into developing multifunctional drug delivery systems to overcome the drawbacks of conventional carriers. Magnetic nanoparticles are not generally used as carriers but can be ... -
Evolución de la enseñanza de las aguas subterráneas en los libros de texto y diseño de una propuesta didáctica para su enseñanza en la educación secundaria
A pesar de que las aguas subterráneas son la mayor fuente de agua dulce líquida en la Tierra, su naturaleza abstracta ha ocasionado que sea el concepto más complicado de entender dentro del ciclo del agua, siendo uno de ... -
La huella litológica de los verracos vetones: análisis geoquímicos de las esculturas zoomorfas de la meseta nordoccidental
Arqueológicamente, el término verraco se aplica a las esculturas zoomorfas vettonas que representan toros o cerdos. El pueblo vetón ocupó un espacio impreciso entre las cuencas de los ríos Tajo y Duero en la Península ... -
High magnetic, transport, and optical uniaxial anisotropis generated by controlled directionally grown nano-sheets in Fe thin films
Fe films with thicknesses between 17 and 95 nm were grown with a nano-sheet morphology, which enabled their high uniaxial magnetic, transport, and optical in-plane anisotropies. The top edge of the nano-sheets was directly ... -
Synthesis strategies of alumina from aluminum saline slags
Aluminum saline slags is a waste of the metallurgical industry that presents serious environmental problems since it needs very extensive areas for its disposal, the toxicity it causes in the atmosphere and groundwater, ... -
Gaseous fueling of an adapted commercial automotive spark-ignition engine: simplified thermodynamic modeling and experimental study running on hydrogen, methane, carbon monoxide and their mixtures
In the present work, methane, carbon monoxide, hydrogen and the binary mixtures 20 % CH4–80 % H2, 80 % CH4–20 % H2, 25 % CO–75 % H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection four-cylinder ... -
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 ... -
Improved adhesion of cathodic arc PVD AlCrSiN coating on ion-implanted WC-Co substrates
Ion implantation has been shown to improve adhesion strength of AlCrSiN coatings due to a synergic enhancement on fracture toughness and load bearing capability of the substrate that can potentially increase the in-service ... -
Differential effect of free-air CO2 enrichment (FACE) in different organs and growth stages of two cultivars of durum wheat
Wheat is a target crop within the food security context. The responses of wheat plants under elevated concentrations of CO2 (e[CO2]) have been previously studied; however, few of these studies have evaluated several organs ... -
Carbon density in boreal forests responds non-linearly to temperature: an example from the Greater Khingan Mountains, northeast China
Boreal forests play a crucial role in the global carbon (C) cycle and in climate stabilization. To better predict global C budgets, it is important to accurately estimate the size of forest C pools, and to identify the ... -
Monitoring structural transformations in metamagnetic shape memory alloys by non-contact GMI technology
(IOP Publishing, 2023) Artículo / ArtikuluaDifferent applications based on metamagnetic shape memory alloy (MSMA) require monitoring the evolution of the martensitic transformation (MT) to optimize the actuation mechanism. To avoid interaction with the active ... -
Tunability of hybrid silica xerogels: surface chemistry and porous texture based on the aromatic precursor
The interest in new materials with specific properties has increased because they are essential for the environmental and technological needs of our society. Among them, silica hybrid xerogels have emerged as promising ... -
Graphene oxide: key to efficient charge extraction and suppression of polaronic transport in hybrids with poly (3-hexylthiophene) nanoparticles
Nanoparticles (NPs) of conjugated polymers in intimate contact with sheets of graphene oxide (GO) constitute a promising class of water-dispersible nanohybrid materials of increased interest for the design of sustainable ... -
Metal-Al layered double hydroxides synthesized from aluminum slags as efficient CO2 adsorbents at pre- and post-combustion temperature
Layered double hydroxides (LDH) have been proposed as the materials that offer the best performance in the moderate-temperature range, between 200 and 450 °C, for CO2 adsorption, so the effect of some synthesis parameters ... -
