We consider a general solution of the electromagnetic wave scattering problem for arbitrarily shaped homogeneous particles, whose surface can be expressed by a function of angular coordinates, using a Laplace series expansion. This can include regularly shaped particles (e.g., ellipsoids and cubes) as well as irregularly shaped particles like Gaussian spheres. For calculations of scattering pro...

In this study, selenium was recovered from an industrial dust. After the purification process, the researchers were able to prepare selenium micro powder. The objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. The results showed that selenium micronized powder and nano particles had high purity. The obtained nanoparticles were t...
