Additive manufacturing (AM) is fundamentally different from traditional formative or subtractive in that it the closest to ‘bottom up’ where a structure can be built into its designed shape using ‘layer-by-layer’ approach rather than casting forming by technologies such as forging machining. AM versatile, flexible, highly customizable and, such, suite most sectors of industrial production. Materials make these parts/objects widely varying type. These include metallic, ceramic and polymeric...
Manufacturing of nanomaterials is an interdisciplinary field covering physics, chemistry, biology, materials science and engineering. The interaction between scientists with different disciplines will undoubtedly lead to the production novel tailored properties. success nanomanufacturing depends on strong cooperation academia industry in order be informed about current needs future challenges, design products directly transferred into industrial sector. It paramount importance selection...
In this work, an extrusion-based 3D printing technique was employed for processing of biobased blends Poly(Lactic Acid) (PLA) with low-cost kraft lignin. Fused Filament Fabrication (FFF) process, objects are built in a layer-by-layer fashion by melting, extruding and selectively depositing thermoplastic fibers on platform. These used as building blocks more complex structures defined microarchitecture, automated, cost-effective minimum material waste. A sustainable consisting lignin...
Superhydrophobic and superamphiphobic toward superoleophobic polymeric surfaces of polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), polydimethyl siloxane (PDMS) are fabricated in a two-step process: (1) plasma texturing (i.e., ion-enhanced etching with simultaneous roughening), varying chemistry depending on the polymer, subsequently (2) grafting self-assembled perfluorododecyltrichlorosilane monolayers (SAMs). Depending absence or not an etch mask colloidal microparticle...
The elucidation of toxicity determinants multi-walled carbon nanotubes (MWCNT) is still incomplete. Functionalization with carboxyl groups is, however, commonly used to mitigate MWCNT toxicity, although the rationale for mitigating effect has not been fully clarified yet. In this work, two optimized chemical vapor deposition methods were employed obtain comparable length but different diameter, which subsequently functionalized. For diameter larger than 40 nm, no detrimental effects on cell...
Structural materials, typically based on metal, have been gradually substituted by high-performance composites carbon fibers, embedded in a polymer matrix, due to their potential provide lighter, stronger, and more durable solutions. In the last decades, industry has witnessed sustained growth, especially diffusion of these materials key markets, such as construction, wind energy, aeronautics, automobile sectors. Carbon fibers are, far, most widely used fiber applications. This important...
The management of energy consumption in the building sector is crucial concern for modern societies. Fossil fuels’ reduced availability, along with environmental implications they cause, emphasize necessity development new technologies using renewable resources. Taking into account growing resource shortages, as well ongoing deterioration environment, performance improvement phase change materials (PCMs) considered a solution that could balance supply together corresponding demand. Thermal...
A classification SAR approach for the toxicity of metal and oxide nanoparticles, towards various cells organisms. The analysis revealed key nanoparticle properties that induce toxicity.
A classification SAR approach is developed for the ecotoxicity assessment of multicomponent nanomaterials. Using their structure and composition, nanomaterials are classified toxicity towards Bacteria, Eukaryotes, Crustacean, Plants, Fish.
Dissimilar friction stir welding between aluminum alloys thick plates reinforced with TiC nanoparticles was conducted. The defect-free welds are characterized by good mechanical mixing the joined materials as well nanoparticle distribution and further grain refinement in comparison unreinforced weld. local behavior of produced metal matrix composites studied compared their bulk counterparts parent materials. Specifically, measured properties microscale nanoscale (namely hardness elastic...
Dissimilar friction stir welds were produced in 3 mm thick plates of AA6082-T6 and AA5083-H111 aluminum alloys using SiC as reinforcing material. The optimum weld presents a good distribution nanoparticles the nugget mechanical mixing two well further grain refinement compared to one without nanoparticles. Higher hardness is also evidenced, followed by enhanced ultimate tensile strength elongation values. All specimens, after test, lead fracture at heat affected zone specifically region...
