Three-dimensional bioprinting is a technology in constant development, mainly due to its extraordinary potential revolutionize regenerative medicine. It allows fabrication through the additive deposition of biochemical products, biological materials, and living cells for generation structures bioengineering. There are various techniques biomaterials or bioinks that suitable bioprinting. Their rheological properties directly related quality these processes. In this study, alginate-based...

Supercapacitors, as an energy storage device, have shown great potential a tool to help solve today's problems. There are currently three types of supercapacitors: electrochemical double layer, pseudocapacitors and hybrid supercapacitors. They aroused interest due their high-power density, fast charging discharging good cyclic behaviour, nowadays, it is necessary continue study in order extend capabilities. This work proposes design fabrication method for supercapacitors with materials guide...

The sharp increase in energy consumption recent years has increased the demand for new storage systems or improvement of existing ones. Supercapacitors are answer to this great challenge needed by any industrialized society. In work, improve system these supercapacitors, composition carbon-based electrodes been modified adding carbon carbonaceous materials and influence porous texture (porosity porosity distribution) on electrodes. Thus, a commercial activated electrode PCO-1000 was...

Three-dimensional extrusion bioprinting technology aims to become a fundamental tool for tissue regeneration using cell-loaded hydrogels. These biomaterials must have highly specific mechanical and biological properties that allow them generate biosimilar structures by successive layering of material while maintaining cell viability. The rheological hydrogels used as bioinks are critical their printability. Correct printability allows the replication biomimetic structures, which great use in...

One of the main European objectives is to promote change consumption towards renewable energies, which have shown a remarkable worldwide growth, problem lies in fact that technologies used, been developed very rapidly during these years, do not sufficiently advanced energy storage systems. The this study design and manufacture supercapacitors suffer corrosion processes with higher performance. To end, supercapacitor connectors designed machined different materials order find one best ensures...

Tissue engineering is a continuously evolving field. One of the main lines research in this field focuses on replacement bone defects with materials designed to interact cells living organism order provide body structure which new tissues can easily grow. Among most commonly used are bioglasses, frequently due their versatility and good properties. This article discusses results production an injectable paste Bioglass® 45S5 hydroxyapatite 3D printed porous by additive manufacturing, using...

3D bioprinting, like printing, is a process that builds structures by depositing material layer layer. In the specific case of these layers are composed biocompatible together with living cells, allowing creation three-dimensional recreate functional tissues and organs. Bioprinting cell-laden complicated high rate cell damage stress occurs during process, caused pressures stresses to which they subjected. To minimise it important study optimise certain bioprinting conditions beforehand...

In recent years, the production and consumption of plastics has increased. This growth in resulted an increasing amount plastic waste, which is a global problem. Among plastics, high density polyethylene (HDPE) one most widely used polymers packaging industry, so its waste recycling process. One main disadvantages accepting recycled HDPE processes odour, makes it impossible to use lines. The aim this work reduce and/or eliminate odours present samples selected for through sepiolites. FTIR...

Las grietas estructurales en pilares, vigas y viguetas pueden suponer un enorme riesgo para la integridad de estructura edificio, ya que progresar hasta extenderse por todo su espesor. Por tanto, es necesario realizar seguimiento evitar aumenten los riesgos y, cuando sea posible, proponer medidas repararlos. De este modo, aumenta probabilidad actuar antes se produzca el colapso estructural. Este trabajo ha producido patentado dispositivo (ES1293890 U) monitorización remota edificios pruebas...

"Insanity is doing the same thing over and again expecting different results". This phrase, attributed to Albert Einstein, contains a message that sums up what happening in education systems. Fortunately, an increasing number of "madmen" are choosing do something "innovate" teaching-learning process. paper shows influence innovating four key aspects learning: instruction, methodology, space time, if we want improve competence performance start make objectives Bologna Declaration reality,...

Tissue engineering is a continuously evolving field. Much research has been done in this field on the replacement of bone defects using scaffolds composed different materials. Among them, bioglasses are frequently used due to their versatility and good properties. This article deals with results production an injectable paste Bioglass® 45S5 hydroxyapatite 3D printed porous structure by additive manufacturing, thermoplastic (PLA). The were evaluated specific application paste, therefore...

Extrusion 3D bioprinting technology aims to make a significant contribution tissue regeneration through the use of cell-loaded hydrogels. These biomaterials must meet very specific mechanical and biological properties that allow them generate biosimilar constructs application successive layers material while maintaining cell viability.The rheological hydrogels used as bioink are decisive in their printability. A correct printability allows replication biomimetic structures great utility...

Electrical conductivity measurement techniques for carbonaceous and powdery materials show a large variation in the results, as electrical resistance is influenced by factors such method itself. Based on four-prong method, cylinders of different dimensions have been designed 3D printed which, together with connectors digital multimeter, made it possible to obtain values varying pressure applied or amount material introduced, giving rise patent (P202130647). The main objective this work has...
