Sensors, Vol. 16, Pages 490: Frequency Management for Electromagnetic Continuous Wave Conductivity Meters

07-Apr-2016 | Mazurek, Przemyslaw ; Putynkowski, Grzegorz, Sensors, 2016

Ground conductivity meters use electromagnetic fields for the mapping of geological variations, like the determination of water amount, depending on ground layers, which is important for the state analysis of embankments. The VLF band is contaminated by numerous natural and artificial ...

Effect of volume ratio of acetonitrile to water on the morphology and property of polypyrrole prepared by chemical oxidation method

12-May-2012 | Zhenhao Huang, Shuchun Hu, Nan Zhang, Xiaolang Chen, Dan Chen, Qian Jin, Xian Jian, Polymer Engineering and Science, 2012

Abstract Polypyrrole (PPY) was prepared by the method of chemical oxidation polymerization in ice bath, and a series of products with different morphology or particle size were obtained through changing volume ratio of acetonitrile to water (VRAW) in the mixed reaction solvents. The structures, ...
