2.Densities and viscosities of the binary mixture of (dimethyl carbonate+methonal) at the temperatures interval (293.15~323.15K) and of (dimethyl carbonate+chlorobenzene) at the temperatures interval (293.15~ 343.15K) were determined under atmospheric pressure by using a vibrating U-shaped sample tube densimeter and Ubbelohde suspended-level viscometer.
3.The magnetic microspheres P(St-co-MAA-co-AM) were prepared by microemulsion polymerization. The morphological,thermal stability and magnetic properties of the microspheres were investigated by different techniques(i.e.SEM,TGA,optical microscopy,vibrating sample magnetometer,FTIR).
4.The magnetic properties were investigated by a VSM with a liquid nitrogen equipment. The Curie temperature can be determined as 285 K according to the M-T curve.
5.The results of magnetic performance by VSM displayed that the magnetic PS nanoparticles exhibited the characteristics of single domain system when saturated magnetization was equal to 31.7 emu·g-1.
6.The effect of deposition parameters,such as pH value and molar ratio of NiSO_4/FeSO_4 on the composition,the structure and the magnetic performance of the deposits was studied by EDX,XRD,TEM and VSM.
7.The magnetic properties of the Fe63-xNd37Alx(x = 5, 8, 10, 12) alloys made by suction casting into the copper mold were investigated by differential scanning calorimetry (DSC), vibrating sample magnetometer (VSM), and the scanning electron microscope (SEM).
8.The effect of Co on crystalline behavior and magnetic properties of Nd-Fe-Al based bulk amorphous alloys was investigated by differential scanning calormrter (DSC), X-ray diffraction (XRD) and the vibrating sample magnetometer (VSM).
9.This dissertation reports the preliminary experimental results of magnetic properties of carbon atom wires (CAWs) and their electrochemical features demonstrated in the anode of lithium-ion secondary batteries A vibrating sample magnetometer (VSM) and an electron paramagnetic resonance (EPR) spectrometer were used in the magnetic investigation and the number of unpaired electrons in CAWs was evaluated.
10.In this article, miniemulsion polymerization and soap-free emulsion polymerization were adopted to prepare magnetic polymer microspheres with different structures. The magnetic polymer microspheres were characterized by X-ray diffraction (XRD), dynamic light scattering (DLS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and thermogravimetric analysis (TGA). Some results have been obtained as follows:
