Abstract null null Porous titanium scaffold has been prepared by freeze casting of TiH2 aqueous slurry for the application of structural core of sandwiches, filters, heat exchangers and bones due to the directional lamellar structure. The effects of freezing temperature and solid content, which are decisive parameter in freezing casting process, on porous structure are revealed. As freezing temperature drops and solid content increases, the porosity ranges from 15% to 73%, wall thickness increas...

Abstract null null Metal-organic framework (MOFs) derived carbon-based nanocomposites are considered as a class of new microwave absorption materials with great application potential. However, it remains a challenge to obtain high-efficiency absorbers based on MOFs with lower filling ratio and wider effective absorption band. In addition, it is difficult to construct uniform interconnection networks of carbon nanotubes (CNTs) in situ on the surface of MOFs derivatives by simple method. Here, we ...

Abstract null null Low melting point liquid metal alloys are progressively utilized in different research fields due to their unique physicochemical properties. Among them, EGaIn is liquid at room temperature with an excellent solubility for reactive metal atoms such as Al. Combined with their characteristic flexible surface, large area and atomically flat interfaces, a library of two-dimensional materials can be generated. Liquid metal synthesis routes provide a highly reproducible thickness of...

Abstract null null The formation of core–shell structure is one of the standard methods to improve the corrosion resistance of carbonyl iron powders (CIPs). In this manuscript, epoxy resin (EP) was coated on the surface of flaky carbonyl iron particles (FCIPs) by a simple one-step polymerization method to form the FCIP@EP composite particles, and they were used to obtained microwave response to accurately simulate, predict and optimize the microwave absorption performance of composites. After be...

Abstract null null The green and facile strategy of producing high efficiency microwave absorption materials (MAMs) has attracted wide attention, but remains a challenge. In this work, polydopamine (PDA) was used as carbon source and nitrogen source, polyvinylpyrrolidone (PVP) was used as protective layer and dispersant, and nanoparticles with concave cube morphology were prepared by self-template eco-friendly method. By adjusting the addition amount of PDA and PVP, the MOF derived materials wit...

Abstract null null Heteroatom nitrogen doping and morphology control have been considered as the effective approaches for improving electromagnetic wave (EMW) absorption ability of carbon-based absorbers. Herein, by controlling the adding dosage of pyridine, thickness controllable MOF-derived Ni@N-doped carbon (Ni@NC) hexagonal nanoflakes presented increased content of doped N atoms and tunable morphology from nanorods-, nanoparticles- to nanoflakes-like. Moreover, it made it possible to adjust ...

Abstract null null In the research of new type of absorbing materials, the influence of special three-dimensional (3D) microstructure and the composite effect of multi-component materials on the electromagnetic properties and absorbing properties of materials has attracted widespread attention. In this work, the 3D flower like ZnFe2O4 ferrite (3D-ZFO) was prepared by two solution chemical precipitation processes, and then a simple ultrasonic and heat treatment process was used to uniformly load ...

Abstract null null Due to the excessively high electrical conductivity and single dielectric properties of the graphene material, when used as a wave absorbing material, the imbalance of impedance matching causes strong reflection effects, resulting in poor wave absorbing performance. In this research, we partially reduced graphene oxide (GO) and loaded magnetic quantum dots (MQDs) through a one-step pyrolysis method, and a novel composite material of three MQDs (Fe, Fe3O4, Fe3C) embedded partia...

Abstract null null Despite the great advantages of the rapid developments in communication technology, it induces several serious intractable problem related to the electromagnetic interference with the environment and human civilization itself. To curb such issues, there is an urgent surge for the research on developing innovative microwave absorbing materials with improved corrosion and oxidation resistance, mechanical properties and microwave absorbing capabilities. In this context, this work...
