Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

In this work, a novel copper nanoparticles-modified graphene (Cu-NPs@GN)-reinforced Al matrix composites were fabricated. The Cu-NPs@GN hybrids were firstly synthesized by an NaCl template-assisted in situ CVD method and then incorporated into the Al matrix to fabricate Cu-NPs@GN/Al bulk composites by cold-press sintering and hot extrusion. With the merit of the unique characteristic of Cu-NPs@GN hybrid, the Cu-NPs@GN/Al composites exhibited homogeneously dispersed GNs and a strong GN–Al interfacial bonding. It was found that the in situ grown Cu-NPs@GN showed much better strengthening effect than that of the ex situ grown counterparts, which might be attributed to the pinning effect of Al2Cu at the interface and thus promote the load transfer efficiency. Compared with pure Al, the composites with only 0.75 wt% Cu-NPs@GN exhibited a 68% increase in tensile strength (224 MPa) as well as had a total elongation of 17.5%.
