Investigators from Prince Songkla University Target Powder Technology

May 13, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Powder Technology are presented in a new report. According to news reporting originating in Songkhla, Thailand, by VerticalNews journalists, research stated, "Nanostructured ZnO films have been successfully synthesized on Zn substrates by a simple hydrothermal method at 120 degrees C in 24 h. The morphologies of the products were controlled by the following alkaline precursor solutions: NaOH, LiOH and NH4OH, which played a role in the crystallization process by generating rod-like, pencil-like and star-like particles, respectively."

The news reporters obtained a quote from the research from Prince Songkla University, "The phase and crystallinity of the nanostructured films were characterized by X-ray diffraction and selected area electron diffraction, the vibrational modes were determined by Fourier transform infrared spectrometry and Raman spectroscopy, and their morphologies were visualized by scanning electron microscopy and transmission electron microscopy. The photoluminescence of the products exhibited a strong, green-yellow band emission at 540 nm."

According to the news reporters, the research concluded: "By using the inhibition zone method, the as-synthesized ZnO nanostructures were observed to inhibit bacterial activity."
