A fully dense Al Al2O3 composite consisting of mostly nanocrystalline Al and γ-Al2O3, a small fraction of ultrafine Al grains and amorphous alumina was produced after four passes from the freshly formed particles.
This was expected, since bDBM (and consequently bECM) material directly derived from bone is known to be a composite of collagens (mostly type I), non-collagenous proteins and growth factors, residual calcium phosphate and retained cellular debris [27].
Nature overcomes a similar issue by arranging natural composites, made of mostly brittle constituents, in discontinuous and hierarchical microstructures.
The structure is made of mostly carbon composites and aluminum-honeycombed plates.
The spotlight shifted from the Dow Jones Industrial Average to the Nasdaq Composite Index Monday amid a flurry of mostly positive news from the tech sector.
The material properties of composites mostly exhibit a scatter due to their in-homogeneity and anisotropic characteristics, brittleness of the matrix and fibre and manufacturing defects.
The work, "Thirteen Most Wanted Men," was a mural-size composite of enlarged police mug shots, mostly of young and good-looking accused felons.
Yesterday, a late selloff in large-cap tech stocks sent the Nasdaq Composite Index down 35 points after a day of mostly apathetic trading.
One important aspect that this study adds to the literature is the description of a complex career decision-making process, with something of a "composite" emerging from mostly one-off interviews of doctors at different career stages.
For samples under study, the powder texture of PMPS/silica composites remained mostly similar to that of the initial oxide suggesting well distribution of PMPS molecules at the surfaces of all nanoparticles.
