DNA is a promising construction material for the supramolecular 'bottom-up' engineering of artificial nanostructured devices. The use of DNA for the selective positioning of macromolecular components, the fabrication of nanostructured DNA scaffolds, as well as the DNA-templated synthesis of nanometer-sized and mesoscopic complexes, consisting of inorganic and bioorganic compounds, are exciting ...
Here we report a novel self-assembly induced solubilization strategy with nanostructured ionic liquids as solvents. Highly ordered mesoscopic structures featuring the solute as a key component, such as liquid crystals, were formed via self-assembly in nanostructured long-chain carboxylate ionic liquids, resulting in extremely high solubilities for sparingly soluble drug molecules.
In this study, The Al 6061 alloy sheets were produced by Cryorolling process and then were welded by resistance spot welding method. In this regard, the solution treated Al 6061 alloy cryorolled subsequently up to 90% reduction in thickness to produce nanostructure alloy. The cryorolled sheets were then subjected to aging treatment (130˚C-30h) in order to obtain simultaneous strength and ductil...
Several properties of bio-inspired surfaces like chemical composition, surface topography, surface hydrophilicity and even surface charge could influence bacterial adhesion to implant materials. Therefore, a nanostructured surface is being investigated to avoid bacterial colonization by their physico-mechanical and chemical aspects. Both smooth and rough-surfaced titanium (PT, SLA) and zirconia...
Al-Zn-Mg/3 wt-% Al2O3 nanostructured composite powder was synthesized through Mechanical Alloying (MA). At first, the 7014 alloy matrix constituents were milled in a planetary ball mill for 20 hours. Then, 3 wt.% µ-Al2O3 particles were added to the pre-milled matrix and the nanostructured composite powder was produced at different MA times to investigate the effects of MA time ...
Strength and ductility are two of the most important mechanical properties of structural materials. However, they are often mutually exclusive, i.e., a material may be strong or ductile, but rarely both at the same time. This is also true for bulk nanostructured materials, which usually have high strength, but disappointingly low ductility. Bulk nanostructured materials are usually synthesized ...
