Abstract Black photothermal materials with broadband solar absorption have attracted great interest for efficient steam generation. However, the solar steam device composed of thermal insulators and water supply paths makes the device more intricate and problematic to operate. Herein, inspired by random close packing structure of beetle, black TiO2 (BTiO2) film with random size distribution is fabricated for simplifying the vapor generation device. The BTiO2 with random size distribution realize...

Abstract Amorphous carbon (a-C) films have been coated on the metallic bipolar plates (BPPs) in Proton Exchange Membrane Fuel Cells (PEMFCs) to improve the corrosion resistance and the interfacial electrical conductivity of metallic BPPs. However, the durability of a-C in the harsh environments of PEMFCs is still confronted with enormous challenges. In this paper, a-C films are prepared on SS316L BPPs via pulsed DC sputtering power with different frequency and the further understanding of corres...

Abstract In this research, the Poisson’s ratio of three different types of almost isotropic interpenetrating composites are designed to be either positive, or negative, or zero. As they are strengthened by a self-connected fibre-network and do not contain any pore in their structure, they all are stiffer than the conventional particle composites. In addition, structural hierarchy is also demonstrated to be able to significantly enhance the auxetic behaviour for the three types of interpenetratin...

Abstract Defect engineering, which is a concept applied to exploit the potential of a given material fully, is also considered when designing materials for energy-related applications. In general, defect engineering focuses on the direct chemical or physical changes caused by defects through varied mechanisms. In this study, sulfur vacancies on the surface of molybdenum disulfide (MoS2) nanoflakes are created easily via hydrogen-etching and are employed to improve the composite uniformity and bi...

Abstract Carbon-based aerogels have demonstrated to have a great promise as advanced microwave absorption materials due to their ultralow volumetric density, unique pore structure, and high electrical conductivity. However, the comparatively complex fabrication process, weak machinability and difficulty in regulation of electromagnetic properties still hinder its large-scale application. Here, we reported a facile and scalable fabrication of novel carbon hybrid aerogels with adjustable electroma...

Abstract Graphite flakes reinforced aluminum matrix (Gr/Al) composites with high thermal conductivity, low thermal expansion and low bulk density have been widely studied. However, the application of Gr/Al composites has been limited due to the low through-plane thermal conductivity as well as poor mechanical properties. In this work, the vertically aligned graphene nanoplatelet (GNP) was initially grown on the surfaces of Gr flakes (Gr(GNP)) by chemical vapor deposition (CVD), and then the Gr(G...

Abstract The interface reaction is the focus of interface control in the graphene/Al composites, but its evolution processes are still unclear. The present work revealed the nucleation and growth mechanisms of the interfacial reaction product, aluminum carbide (Al4C3), in the graphene nanosheet (GNS)/Al composites. The nucleation of Al4C3 was found to mainly start at the open edge of GNSs due to the high chemical reactivity, and the formed Al4C3 was found to mostly locate either along or at an a...

Abstract Effective joining techniques are urgent and necessary for the rapid developments and widespread applications of aluminum matrix composite (AMC) components. Friction stir welding (FSW) is a very promising method for joining AMCs without clear defects, while double-sided FSW is especially preferred in joining thick or ultra-thick AMC plates. The overlapping region stirred twice by the two welding passes is formed during the double-sided FSW, which has an important effect on the microstruc...
