Hirarchical Multi-ferroic FeBiO3 Nanoparticles Prepared by a Facile Solvothermal Method: Undergraduate Experiments for Inorganic Chemistry
Baoxiang Wang, Zhaobo Wang, Zhiyan Guo, Ruotao Feng, Fanglin Du
Journal of Laboratory Chemical Education, 2018, 6(3), pp. 60-64
DOI: 10.5923/j.jlce.20180603.02
Open Access
Wetting chemical method is a common method for the preparation of nano-materials, which are useful for experimental study by undergraduate students. Hierarchical multi-ferroic FeBiO
3 nanoparticles were prepared by a facile solvo-thermal method and adopted as dispersing materials for electrorheological (ER) fluids. The morphology of FeBiO
3 nanoparticles was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The structure was characterized by X-ray powder diffraction. Moreover, the electrorheological (ER) behavior of FeBiO
3 nanoparticles was characterized using a rotational rheometer.

The impact of rainfall and wet pavement has the potential to influence the number of traffic crashes along a roadway as the reduction in pavement friction and visibility potentially lead to a greater number of crashes. To study this impact, researchers have used traffic crash records with reported roadway conditions to determine if there is a relationship between the rainfall event and the number of traffic crashes. This paper examines the accuracy of the reported roadway condition related to the presence of rainfall using a crash database and rainfall records from gauges throughout the state of Alabama. The results of this study indicate that there is a high likelihood, or almost 12 percent of the crashes in the database, where the pavement condition will be reported as wet when there is no rainfall occurring in the area and when there was not a report of rainfall in the recent timeframe. This high percentage of incorrect values might influence the results of statistical studies intended to evaluate the influence of rainfall on crashes.
