Synthesis and Characterization of Multiferroic NiFe2O4/BiFeO3 Nanocomposites by Modified Pechini Method Xianming Liu1, a, Wenliang Gao2, b 1 College of Chemistry and Chemical Engeering, Luoyang Normal University, Henan Luoyang 471022, China 2 College of Chemistry and Chemical Engineering, Chongqing University, Chongqing 400044, China alliuxianming@yahoo.com.cn, bgaowl@cqu.edu.cn Keywords: Spinel; Perovskite; Multiferroics; Magnetoelectrics Abstract.
The structure and morphology of the composites were examined by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM).
The structure and the interface chemistry of BiFeO3/NiFe2O4 composite films or paprticles were invetigated due to their particular dielectric, magnetic, and magnetoelectric properties [6-9].
The phase structures of the as-prepared samples were determined on a powder X-ray diffraction (XRD) system (PW1830, Philips) with CuKa radiation.
All diffraction peaks for the materials correspond to spinel-perovskite mixed structure shown in Fig. 1c, suggesting that the powders are largely crystallized into a mixed phase of spinel-perovskite structure without traces of any impurity phases.

Biotemplate synthesis which means applying the biological tissues as templates and replicating the natural structure onto the materials is a new pathway to prepare the nano/micro materials with special structure and morphology.
Results and Discussion Structure and Morphology of the Pollen Grains.
The hollow structure of the SiO2 microsphere was investigated through some broken ones.
Furthermore the pore structure of the microspheres could also be affected by the amount of the TEOS.
The adsorption properties of the microspheres with different pore structures were studied.

Next, a dry etching process was employed to etch the 2 µm oxide hard mask under a photoresist (PR) mask using C4F8/Ar/O2 gas chemistries.
Each loop in the recipe consisted of 3 steps, having suitable gas chemistry for physical sputtering, SiC etching, and biproducts polymer removal during etching.
Arrow like structures in the center of the trench is coming from the Platinum coating on the sample.
It has been previously demonstrated that dense structures are more easily smoothed by the dry etching process than loosely packed structures [7].
As depicted in the crystal images in Table 1, the crystallographic orientations of -60° and -75° are more closely packed, systematic, and homogeneous structures.

However, the adsorption by activated carbon has been widely utilized as an adsorbent because activated carbon (AC) mainly consists of elementary carbon in structure.
During the activation process, the unique internal pore structure is created.
The chemical structure consists of amino acids have acidic site as a result of the carboxylic acid functional group , -COOH, and basic sites as a result of the amino group, -NH2[4].
