Synthesis and microwave absorbing properties of FeCo alloy particles/graphite nanoflake composites

Facile synthesis, magnetic and microwave absorption properties of Fe3O4/polypyrrole core/shell nanocomposite

“…There has been a growing and widespread interest in microwave absorption materials for many years as a result of the serious electromagnetic interference pollution arising from mobile phones, radar systems and various electronic devices [1][2][3]. Magnetite as a conventional microwave absorption material has drawn considerable attention because of its high specific resistance and excellent microwave absorption property.…”

Synthesis and characterization of nanosized urchin-like α-Fe2O3 and Fe3O4: Microwave electromagnetic and absorbing properties

“…For this purpose, extensive studies have been carried out to exploit new and high efficient absorbents to prevent such phenomena. Among all the contenders, new type nanomaterials with complex nanostructures have attracted considerable attention owing to their unique chemical and physical properties [1][2][3][4][5][6], especially as microwave absorbing and shielding materials [7][8][9][10][11][12]. For example, Cao et al [8] prepared cagelike ZnO/SiO 2 nanocomposites with the maximal attenuation of 10.68 dB at 12.79 GHz.…”

Resistance to Oxidation at 150℃ of Sub-Micrometer Diameter Silver-Coated Copper Particles Produced by Wet Chemical Synthesis and Immersion Plating

“…The increase in size observed in the sample with a ratio of 5:5 is attributed to an increase in agglomeration due to collision between primary Cu particles that are explosively formed during synthesis in the absence of a surfactant. [21][22][23] The yield of Cu particles obtained through synthesis at 90 C for 20 min with different volume ratios of hydrazine hydrate to ammonium hydroxide, as shown in Fig. 5, was calculated by dividing the weight of Cu particles obtained by the weight of Cu in the precursor.…”
