Abstract Boron nitride nanosheet/copper (BNNS/Cu) nanocomposites were fabricated using a molecular-level mixing process. This process was facilitated by electrostatic interactions between negatively charged functional groups on the BNNSs and Cu metal precursor ions. The mixing process induced the formation of oxygen (O)-mediated bonding between BNNSs and the Cu matrix, which enabled enhanced dispersion of BNNSs and interfacial bonding with the Cu matrix. The mechanical properties of the resultin...

Novel one-dimensional template-grown coaxial SiC@carbon nanotubes (SiC@CNTs) were fabricated using a chemical vapor deposition method. To facilitate the formation of SiC on CNT template, a molecular-level mixing process was used to coat the surface of commercial multiwalled carbon nanotubes (MWCNTs) by Fe2O3. These Fe-CNTs were transformed into SiC@CNT nanotubes, which were then mixed with Al6061 alloy and consolidated by spark plasma sintering to obtain Al6061-SiC@CNT nanocomposites. The additi...

Abstract Graphene reinforced copper matrix (graphene/Cu) nanocomposite powders are fabricated by the molecular-level mixing process and consolidated by spark plasma sintering and pressureless sintering process followed by hot isostatic pressing for the full densification. The addition of 1.2% volume fraction of graphene in Cu matrix resulted in 1.9 and 1.3 times increase in yield strength and elastic modulus, respectively, in comparison to those of pure Cu fabricated by same sintering process. H...

Abstract Graphene fibers are regarded as a novel platform material for flexible electronic applications based on their superior electrical conductivity, mechanical properties and potential for mass production. However, properties of graphene fibers are still far from commercial level and considerable effort has been made recently to improve these characteristics. In this paper, we drastically enhanced both the mechanical and electrical properties of graphene-based fibers by converting infiltrate...

We explore two small molecules containing arms of dicyano-n-hexylrhodanine and diathiafulvalene wings terminated with benzothiadiazole linker, denoted as BAF-4CN and BAF-2HDT, respectively, as small molecule non-fullerene acceptors (SMNFAs) in organic solar cells. The proposed materials are mixed with a low band gap polymer donor PTB7-Th having broad absorption in the range of 400–750 nm to form solution-processed bulk heterojunctions (BHJs). The photoluminescence (PL) measurements show that bot...
