Plasma sprayed zirconia deposits have been employed in wide applications for thermal protection. Recently, the use of nanostructural surface represents an alternative for improving the performance of these coatings. The present paper reviewed the works in this field at our research group, including synthesis of nanostructural ZrO2 powders, influence of spraying parameters on microstructure and ...

Copyright © 2012 Frederick Furness Publishing 14 Nasal sprays that deliver active ingredients using droplets are well-established drug delivery vehicles, both for locally acting and systemic therapies. More recently, though, the pharmaceutical industry has started to turn its attention to delivering dry powders via the nasal route, a step that parallels the introduction of dry powder inhalers (...

Composite material based on Fe3Si micro-particles and Mn-Zn nano-ferrite was prepared using powder metallurgy technology. The sol-gel followed by autocombustion process was used for synthesis of Mn0.8Zn0.2Fe2O4 ferrite. 3 wt.% of mechanically milled ferrite was mixed with Fe3Si powder alloy. Mixed micro-nano powder system was homogenized by the Resonant Acoustic Mixing using ResodynLabRAM Mixer...

Solid freeform fabrication (SFF) methods for metal part building, such as three-dimensional laser cladding, are generally less stable and less repeatable than other rapid prototyping methods. A large number of parameters govern the three-dimensional laser cladding process. These parameters are sensitive to the environmental variations, and they also in ̄uence each other. This paper introduces th...

The main objective of this study was to prepare Risperidone (RIS) nasal powder by spray drying method, so as achieve controlled drug release and high deposition efficiency in the cavity. microparticles with uniform size controllable structure were prepared mixing hydroxypropyl -βcyclodextrin (CD) API before a novel microfluidic technology. properties particles characterized terms particle size,...

The combined terahertz time-domain spectroscopy (THz-TDS) and chemometric technology is used to detect the adulteration of similar substances in Panax notoginseng powder. Four kinds samples are prepared experiment, three adulterated powder adulterating with zedoary turmeric powder, wheat flour, rice respectively. values concentration from 5% 60%, interval 5%, other sample pure modeling predicti...
