Evolution of Pentagonal Nano- and Micro-Objects in Temperature Fields.

The effect of temperature and annealing atmosphere on the structure and morphology of small icosahedral copper particles and filamentary pentagonal crystals has been investigated. Particles and filamentary crystals were obtained by electrodeposition of metal, and their structure and morphology were investigated by electron microscopy and x-ray diffraction. It has been shown that during annealing, whiskers are formed on the surface of the particles together with porous and 'flake' structures, and cavities are formed inside them. [ABSTRACT FROM AUTHOR]
