Científicos de todo el mundo trabajan para lograr formas más eficientes de proteger los metales de la corrosión. Una de las formas más empleadas por mejorar otras propiedades además de la resistencia a la corrosión en aceros, es la reducción química de níquel. Cuando se emplea hipofosfito como agente reductor en este proceso, se desarrollan...

Actualmente, existe la necesidad de desarrollar nuevas técnicas más sostenibles para la incorporación de fertilizantes al cultivo. Así se ha planteado la liberación controlada de estos fertilizantes a partir de matrices proteicas biodegradables de soja. No obstante, su técnica de obtención se debe optimizar, ya que supone una incorporación...

The nanoparticles (NPs) synthesis poses an environmental problem: the formation of other toxic substances. An eco-friendlier alternative method based on the use of polyphenolic extracts is gaining interest due to their potential to reduce metal salts for the formation of NPs without toxic products. Thus, the main objective of this work was to...

Biomaterials have been used since ancient times. However, it was not until the late 1960s when their development prospered, increasing the research on them. In recent years, the study of biomaterials has focused mainly on tissue regeneration, requiring a biomaterial that can support cells during their growth and fulfill the function of the...

A lo largo de la historia, se han desarrollado diferentes técnicas para la elaboración de andamios para Ingeniería Tisular. No obstante, en estudios recientes se ha realzado el uso de la bioimpresión 3D para esta aplicación debido a su facilidad para definir la estructura del material garantizando su reproducibilidad. Por tanto, en el presente...

Currently, gelatin-based films are regarded as promising alternatives to non-environmentally friendly plastic films for food packaging. Nevertheless, although they have great biodegradability, their weak mechanical properties and high solubility limit their applications. In this way, the use of nanoparticles, such as FexOy-NPs, could improve...

Regenerative medicine is increasingly focused on the development of biomaterials that facilitate cell adhesion and proliferation through the use of natural polymers, which have better biocompatibility and biodegradability. In this way, the use of hydrogels has been considered as a potential option for tissue engineering due to their physical...

The electrospinning process is an emerging and relatively easy technique to prepare three-dimensional matrices with micro- and nanofibers. To achieve it, aqueous polymer solutions from synthetic or natural polymers are used. PVA was selected as polymer and gelatin because of its biocompatibility and biodegradability. A complete characterization...

Controlled release systems are increasing their presence on the market. However, their use is not generating a great impact on horticultural production, mainly due to their price, which makes crop production more expensive. This work proposes a cheaper alternative for the manufacture of these devices. Thus, an agri-food byproduct (soy protein...

Conventional plastics can be substituted for protein-based bioplastics due to their natural origin and their biodegradability. Nevertheless, their properties are inferior to those obtained for synthetic plastics. The chemical crosslinking of these bioplastics with aldehydes could improve their properties to compete in the actual market. Thus,...

La situació actual ha generat la necessitat de replantejar- se l'ensenyament no presencial. No obstant aixo, aquest tipus d'ensenyament en carreres cientificotecniques pot tenir grans inconvenients. Per aquest motiu, en aquest treball es planteja una comparativa entre l'elaboració de practiques presencials i no presencials en assignatures...

Estudios recientes han propuesto el uso de matrices bioplásticas de proteína de soja para la incorporación controlada de micronutrientes a los cultivos, mitigando así el uso excesivo de fertilizantes en horticultura. No obstante, la incorporación de los micronutrientes reduce la capacidad superabsorbente de estas matrices, limitando su uso como...

Climate change and the enhancement of ecology have generated the need to create packaging that is biodegradable and, at the same time, allows food to be preserved efficiently in order to avoid the accumulation of plastic and minimize food waste. In this sense, protein-based bioplastics are a promising alternative, but due to their limited...

In recent years, tissue engineering research has led to the development of this field by designing scaffolds with better properties that can fulfill its purpose of better and faster tissue regeneration, consequently improving people's quality of life. Scaffolds are matrices, predominantly composed of polymeric materials, whose main function is...

La acumulación de plásticos ha generado la necesidad de crear envases biodegradables que al mismo tiempo permitan la conservación eficiente de los productos. En este sentido, los bioplásticos a partir de subproductos son una alternativa prometedora, pero debido a sus limitadas propiedades necesitan tratamientos adicionales para competir con los...

El desarrollo de biomateriales abarca tres etapas diferentes: selección de materia prima, técnica de procesado y caracterización del producto final. Entre ellos, los hidrogeles se han presentado como candidatos potenciales en aplicaciones farmacéuticas y biomédicas por sus propiedades fisicoquímicas. La mayor parte de los estudios sobre...

El uso de materiales superabsorbentes ha aumentado recientemente en horticultura ya que presentan grandes ventajas como la eficiencia en el uso del agua en periodos de sequía, siendo capaces de retener agua y suministrarla a los cultivos conforme a su necesidad. No obstante, estos materiales superabsorbentes están hechos con polímeros...
