Ordered morphology control

In order to control spot deposihon and ultimately spot diameter and morphology, one must first control the rate of evaporation from the quill reservoir. The change in surface tension causes variations in spot characteristics. Evaporation of water from fhe bulk solution held in the quill reservoir increases the salt and probe concentrations, which in turn increases the... 

The broad distribution of the lengths and diameters of the final nanotubes is probably caused by the same broad size-distribution in the templating [Pt(NH3)4](HC03)2 nanofibers. During the coating process obviously no drastic changes in the morphology occur. In order to control the size of the nanotubes, the emphasis should be put on the effort to control the precipitation of the metal-salt nanofibers. 

Strontium ferrite SrO-6Fe2O3 doped with various oxides was studied. The oxides were added in order to control calcination processes and to fabricate the magnetic material with required structure and morphology of grains. However, besides of the introduced oxides the target sample can contain some impurities, which occur in the feed stock, e.g. in kaolin. According to emission analysis the... 

Crystal Morphology Crystal morphology determines the mechanical properties, the biodegradability, and the biocompatibility of polymers. Thus, it is necessary to understand the mechanism of polymer crystallization in order to control the polymer microstructure and, thereby, its properties. The crystallinity and cavitation of polymers have been studied using optical and in situ electron microscopy as complementary techniques, among many others. 

In order to control the particle morphology and size, surfactants may also be applied to the Polyol process [79, 80]. 

The crystallization kinetics and thermodynamics must be fully understood, in order to control the solid-state morphology that ultimately provides the desired...
