The research shows a bioinspired approach to be adopted design of systems based on Shape Memory Alloys (SMAs), class Smart Materials that has in common with muscles the capability react an impulse (thermal for SMAs) contraction. biomechanically inspired machine is discussed paper refers antagonistic pairs, which belongs Skeletal Muscles and are normally arranged opposition so as one group contract another relaxes or lengthens. study proposes model, solution not only specific application, but...
In this text, we intend to answer the following question: is Augmented Reality an enhancer for Higher Education students in math's learning? For purpose, define augmented reality and present a state of art mapped mainly by studies that focus AR educational contexts. We also describe our research, including methodological aspects data collection creation 3D contents AR. Then, synthesize analysis some preliminary data, briefly presenting perceptions practices learning with contents. Finally,...
Bone tissue engineering has been developed in the past decades, with of bone substitutes on vanguard this regenerative approach. Polycaprolactone-based scaffolds are fairly applied for regeneration, and several composites have incorporated so as to improve scaffolds' mechanical properties in-growth. In study, hydroxyapatite is polycaprolactone-based at two different proportions, 80:20 60:40. Scaffolds produced blending methods, solvent casting melt blending. The prepared 3D printed through...
This comprehensive review explores advancements in the design, fabrication and performance evaluation of three-dimensional (3D) printed antennas, across different frequency ranges.The highlights use diverse printing methods, materials structures, to achieve specific antenna characteristics designs, such as wide bandwidth, high gain, circular polarization, beamforming capabilities.Simulation measurement results are compared assess performance, considering parameters impedance radiation...
This study investigated the factors affecting properties of geopolymer (GP) mortars through a two-stage experimental program created central composite design experiments. Stage I focused on effects SiO₂/Al₂O₃, H₂O/Na₂O, and total water-to-total solids (W/S) ratios formulated using metakaolin (MK) as only geopolymerization precursor, while II evaluated impact introducing biomass fly ash (BFA) second precursor. Most importantly, SiO₂/Al₂O₃ ratio was defined based raw materials' dissolution...
In this paper an integrated methodology for implants personalized manufacturing is presented. This materializes the hybrid material through integration of two or more advanced Additive Manufacturing (AM) technologies. Furthermore, high strength biomechanical with optimized geometry and mass can be manufactured by biomimetic concepts application. The combination polymers ceramics metal materials (or alloys) allows a significant leap in development production great diversity components...
Biomaterial properties and controlled architecture of scaffolds are essential features to provide an adequate biological mechanical support for tissue regeneration, mimicking the ingrowth tissues. In this study, a bioextrusion system was used produce 3D biodegradable with architecture, comprising three types constructs: (i) poly(ε-caprolactone) (PCL) matrix as reference; (ii) PCL-based reinforced cellulose nanofibers (CNF); (iii) CNF hydroxyapatite nanoparticles (HANP). The effect addition...
The actual demand for sustainable construction has fostered the research of alternative products made new materials, such as composites based on renewable resources obtained directly from nature or, most importantly in this context, wastes industries thus encouraging implementation recycling processes. This study reports optimization wood plastic (WPC) industrial residues pine sawdust, high density polyethylene (HDPE) and maleic anhydride-grafted-polyethylene (PE-g-MA) coupling agent. These...
Recycling is crucial for the conservation and improvement of environment. The reduction natural resource exploration recovery waste are examples actions to contribute a sustainable development. Waste from end-of-life tires undifferentiated plastics represents an environmental problem due very high number tons used produced, but with economic potential because their incorporation into value-added products issue utmost importance. manufacturing technologies oriented increase in quality levels,...
In recent years, concerns about environmental preservation have motivated industries to adapt towards more environmentally friendly materials, resorting for this recycled and waste materials. This has been the center a growing number of research studies enable less virgin materials [1], [2]. The use thermoplastics considered production wood plastic composites in years [3]. New developed with view developing eco-composites, several advantages, both at an level ecological level, including...
The pandemic situation caused by coronavirus clearly demonstrated the need for alternatives able to protect respiratory tract and inactivate infectious agents. Based on this, antibacterial face-mask filters of polycaprolactone (PCL) dopped with magnesium oxide (MgO) copper (CuO) nanoparticles (NPs) were produced using an electrospinning technique. A morphological analysis electrospun meshes evaluated success nanoparticles' incorporation as well average fibers' diameters (481 ± 272 nm)....
Among natural fillers, cork has been acknowledged as a suitable alternative of other cellular materials that are widely employed in engineering applications due to their low conductivity heat, noise and vibration, high abrasion resistance flexibility, compressibility ratio, among characteristics [1]. The eco-friendly features fillers based composites make them very promising sustainable solution large markets mainly if additive manufacturing technologies, such 3D printing, used [2]. Through...
