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...

26Additive manufacturing technologies offer a multitude of medical applications due to the advances in development materials used reproduce customized model products.

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.

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...

Building sector is a major contributor to the emissions of pollutant gases, which are responsible for health-damaging effects climate change. To quantify and reduce these emissions. This comparative study presented between two buildings that could have sanitary or any other type use. Both similar characteristics, except their structures, one made metal concrete. The design, structural calculation three-dimensional dimensioning were performed using Information Modeling (BIM). budget product...
