Solar steam generation has been considered as an effective way to solve the shortage of freshwater resources. In this paper, we have designed an interfacial evaporation device for efficient solar steam generation based on near infrared (NIR)‐absorbing lanthanum hexaboride (LaB6) nanoparticles and melamine sponge (MS) as the skeleton. LaB6 nanoparticles as a photothermal conversion material can absorb the NIR light and convert it into heat. Due to the porous 3D network and better hydrophilicity of MS, it can act as a substrate to support the LaB6 dispersed on the surface and transport the water by the capillary force. The evaporation rate of 1.13 kg m−2 h−1 and photothermal conversion efficiency of 60.7% under 1 kW m−2 solar illumination were achieved. Moreover, LaB6‐MS photothermal conversion device (LaB6‐MS PTCD), with excellent chemical stability could purify different water sources such as simulated seawater, strong acid, strong alkaline, and dyed methylene blue solution, exhibiting promising application in highly efficient solar energy‐driven seawater desalination and wastewater purification.

SiCp/A390 composite was fabricated by powder metallurgy method and hot extrusion process. The interfacial microstructure of SiCp/A390 composites after heat treatment was characterized by HRTEM. The results show that the interface between SiC and Al matrix has an orientation relationship of [4510] SiC //[011] Al , (1010) SiC //(111) Al and forming a semi-coherent interface. The crystallographic orientation relationship between SiC and Si in the SiCp/A390 composites is [010] SiC //[001] Si , (004) SiC //(220) Si. The interplanar spacing of Al matrix on lattice plane (111) is close to the twice interplanar spacing of the Si phase on lattice plane (400). They keep a semi-coherent crystal plane, with an orientation relationship of [011] Al //[001] Si , (111) Al //(400) Si .

“…Recently, the mechanical properties and corrosion behavior of Al/SiC (comprising 20 vol.% SiC) composites fabricated by vacuum hot pressing sintering at 700°C under a pressure of 20 MPa were studied by Zhang et al [15], in their work the high relative density of 99.65 ± 0.08% for the Al/SiC composite can be obtained. Cold isostatic compaction of Al/SiC composite powders with different content of nano SiC particulates as the reinforcement was experimentally performed by Bajpai et al [16], where various properties such as hardness, density, porosity, compressive strength, indirect tensile strength and the microstructure of the samples were measured and characterized.…”

Uniaxial die compaction of two-dimensional (2D) Al/SiC core/shell (core: SiC; shell: Al) composite powders with different initial packing structures was numerically reproduced using DEM-FEM coupled MPFEM modeling from particulate scale. The effects of external pressure, initial packing structure, and SiC content on the packing densification were systematically presented. Various macro and micro properties such as relative density and distribution, stress and distribution, particle rearrangement (e.g. sliding and rolling), deformation and mass transfer, and interfacial behavior within composite particles were characterized and analyzed. The results show that by properly controlling the initial packing structure, pressure, and SiC content, various anisotropic and isotropic Al/ SiC particulate composites with high relative densities and uniform density/stress distributions can be obtained. At early stage of the compaction, the densification mechanism mainly lies in the particle rearrangement driven by the low interparticle forces. In addition to sliding, accompanied particle rolling also plays an important role. With the increase of the compaction pressure, the force network based on SiC cores leads to extrusion on Al shells between two cores, contributing to mass transfer and pore filling. During compaction, the debonding between the core and shell of each composite particle appears and then disappears gradually in the final compact.
