In this work, SrFe12O19 samples were synthesized by hydrothermal method. We systematically studied the influence of an alkaline environment (NaOH) with the molar ratio (R) of 2 , 3 and 4 on the structure, magnetic properties of SrFe12O19 particles prepared by hydrothermal method. The relation between morphology, magnetic properties and microwave absorption properties of materials have been investigated.

his paper investigates the nonlinear vibration of imperfect smart sandwich plate which consists of an auxetic graphene reinforced metal matrix composite (GRRMC) core layer integrated with two magneto-electro-elastic face sheets. The Poisson’s ratio of the GRMMC core is negative while the material properties of magneto-electro-elastic face sheets depend on the volume fraction of piezoelectric and piezomagnetic phases.

This paper presents a method for establishing the exact receptance function of a tapered axially functionally graded (AFG) beam with nonlinear ratios of properties using the Adomian method. In current papers, the Adomian method was applied for linearly tapered beams where the geometric series was used conveniently.

This study determined effect of nano TiO2 ratio on some properties of wood plastic composite (WPC), especially ultraviolet (UV) resistance of the material. Research results showed that, the TiO2 nanoparticles did not significantly affect bonding quality between wood flour and plastic, it means when adding nanoparticles into WPC, the strength of material was almost unchanged.

This paper investigates the influence of intergranular friction and grain size distributions on the initial void ratio of a granular sample subjected to isotropic compression loading. In the field of geomechanics, besides the loading path and evolution of microscopic properties, the initial void ratio is a crucial and key factor that governs the mechanical behavior of geomaterials.

Two copper phyllosilicates were prepared via co-precipitation accompanied by hydrothermal treatment at pH constant. The obtained materials were physically characterized by XRD, H2-TPR, TEM, BET and XPS techniques. The results indicated that Cu(II) ions were successfully intercalated into the phyllosilicate framework at a low Cu/Si molar ratio.

We report on the improved stability and yield of silver nanorods with well controlled aspect ratios synthesized using a modified seed mediated approach conducted at room temperature. It is found that the longitudinal surface plasmon resonance of these nanoparticles can be tuned in the spectral range 400e 700 nm by varying the concentration of seed particles.
