Yeast-derived biosynthesis of silver/silver chloride nanoparticles and their antiproliferative activity against bacteria [PDF]

, 2016
Here, we provide the first evidence of yeast strains assisted Ag/AgCl-NPs production in vitro. The formed nanoparticles were characterized by spectroscopic and electron microscopy approaches. UV-vis supported the biosynthesis. TEM analysis evidenced that

Scanning tunneling microscopy (STM) and scanning electron microscopy (SEM) of electrodispersed gold electrodes [PDF]

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988
Abstract Images of large active surface (electrodispersed) gold electrodes obtained by electroreduction of an oxide layer grown by applying a fast periodic square wave potential to polycrystalline specimens, have been obtained by STM and SEM. For the first time a correlation of imaging data of both microscopes can be established which allows one to ...
