Titanium and its alloys are reference materials in biomedical applications because of their desirable properties. However, one the most important concerns long-term prostheses is bone resorption as a result stress-shielding phenomena. Development porous titanium for implants with low Young’s modulus has accomplished increasing scientific technological attention. The aim this study to evaluate viability, industrial implementation potential technology transfer different powder-metallurgy...
A great variety of powder metallurgy techniques can produce biomimetic porous titanium structures with similar mechanical properties to host bone tissue. In this work, loose sintering and space holder techniques, two frequently used metallurgical are compared evaluate the influences porosity (content, size, morphology wall roughness), (stiffness yield strength) in-vitro cellular responses (adhesion proliferation myoblasts osteoblasts). These comparisons made achieve best balance between...
Although biofilm formation is a very effective mechanism to sustain bacterial life, it detrimental in medical and industrial sectors. Current strategies control proliferation are typically based on biocides, which exhibit negative environmental impact. In the search for environmentally friendly solutions, nanotechnology opens possibility interaction between biological systems colonized surfaces by introducing nanostructured coatings that have potential affect adhesion modifying surface...
Commercially pure (c.p.) titanium grade IV with a bimodal microstructure is promising material for biomedical implants. The influence of the processing parameters on physical, microstructural, and mechanical properties was investigated. achieved from blends powder particles different sizes, while porous structure obtained using space-holder technique (50 vol.% ammonium bicarbonate). Mechanically milled powders (10 20 h) were mixed in 50 wt.% or 75 c.p. titanium. Four mixtures precompacted...
Bone resorption and possible fracture of host tissue are some consequences resulting from the mismatch between Young's Modulus constituent materials implants bone that compromises reliability for replacing damaged tissue. The use functional graded porous presents an interesting approach could help decrease modulus while simultaneously mimicking highly hierarchical porosity structure. However, these structures more difficult to fabricate than those with homogenous porosity. design...
In today's world, it has become very common to find engineers working on multinational projects. As a result, educational institutions need prepare students succeed in this global environment by incorporating collaborative projects as learning experience. At the same time, should be aware of importance experience, recognize its benefit, and motivated participate It is documented literature that students' interest motivation are important factors contributing process any discipline,...
Multinational teams working in engineering solutions are becoming a common practice many industries around the world because companies interested capitalizing on human resources dispersed globally. This has increased significantly due to advancements information and communication technologies (ICT). The effectiveness of those geographically been topic interest for authors this paper particularly interaction among team members since literature recognizes that achieve better results when is...
The copper foam is an interesting field of research because its several advantages as engineering material. Powder metallurgy presents alternative route to obtain a porous structure with high strength weight ratio and functional properties. viability processing separately two different space-holders such ammonium hydrogen carbonate (NH4HCO3) sodium chloride (NaCl) 50 vol% was studied. green compacts obtained under 200 MPa were sintered at cycles for the complete removal space-holder. foams...
The softening elastoplastic models present an unsuitable behavior after reaching the yield strength: unbounded strain localization. Because of material instability, which is reflected in loss ellipticity governing partial differential equations, solution depends on discretization. work proposes to solve this dependency using meshless Finite Points Method. This meshfree spatial discretization technique allows enriching equations gradient’s plasticity and introducing internal length scale...

Engineers have the responsibility to identify and develop sustainable, culturally relevant solutions global problems. Consequently, an engineering education must necessary knowledge, skills, attitudes find viable, desirable, feasible sustainable solutions. One of main challenges in education, however, is identification appropriate model educate students area sustainability. The aim this paper a methodology based on case study approach that effectively exposes required for decision making...
Titanium (Ti) and its alloys are used for biomedical applications because of their high resistance to corrosion, good strength-to-weight ratio, fatigue resistance. However, a problem that compromises the performance material is mismatch between Young’s modulus Ti bone, which brings about stress shielding. One strategy has been investigated reduce this difference manufacture Ti-based foams, using powder metallurgy (PM) methods, such as space-holder technique. in uniaxial compaction, both...
Development of titanium foams with low Young’s modulus as a potential implant material has attracted significant attention.
