Nanotechnology is the engineering of purposeful systems at the molecular scale. It has an impact on every industry counting semiconductors, manufacturing, and biotechnology. Biomedical nanotechnology, bionanotechnology and nanomedicine are increasing biomedicine offered hybrid fields. The oncoming generations of nanoscale biomedical/pharmaceutical products will have object specificity, carry mu...
The development of novels materials represents a new and fast evolving application of research in physics and medicine. Processing synthesis is critical because it generally controls the final properties of the materials, ceramic forming techniques are generally based on powder processing with powder synthesis, forming and sintering. Moreover, ceramic processing has also to consider other techn...
objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...
Porous yttria-stabilised zirconia ceramics have been gaining popularity throughout the years in various fields, such as energy, environment, medicine, etc. Although yttria-stabilised zirconia is a well-studied material, voided yttria-stabilised zirconia powder particles have not been demonstrated yet, and might play an important role in future technology developments. A sol-gel synthesis accomp...
Due to the conventional understanding of sintering phenomenon in ceramic materials, considering two words of “cold” and “sintering” together may arise a doubt to a ceramic engineer since the usual sintering process has been accompanied by a heating regime at elevated temperatures. Recently, a new technique called Cold Sintering Process (CSP) has been introduced and developed as an ultra-low tem...
This paper presents actually work from development of mechatronic handling devices able to accomplish certain microand/or nano operation tasks. Piezo ceramic structures with (3,1)-piezoelectric effect integrated into the mechatronic system will be used an actuation element. The subject of this paper is structures with more than 1 degrees of freedom appropriate for different microand nano-applic...
The effect of Cerium and Cobalt substitution in Zinc ferrites with respect to their electrical and magnetic properties has been investigated in this paper. The nanoparticles of Zn1-x-y Cex Coy Fe2O4 ( x = 0.012, 0014, 0.016, 0.018; y = 0.01, 0.001, 0014, 0.016) is prepared by sol gel route and sintered in a microwave furnace. The nano size, structure and composition of Ce-Co doped Zinc ferrite ...
Choline chloride-malonic acid deep eutectic solvent (Cm-DES) was employed to synthesize Zr0.8Sn0.2TiO4 nano-powders using Zr(CH3COO)4, SnCl2∙2H2O, and Ti(OCH3CH3)4 as raw materials. The nano-powder with the mean grain size of 10.7 nm obtained at 450 °C, significantly lower than that by conventional mixed oxide routes. Meantime, densification ceramics improved as-synthesized powder. relative den...
Nano-particles of polycrystalline Zn Fe2 O4 are prepared using sol-gel method with Ni, and Sm. They are obtained as dried gel after the successful chemical reaction of their respective metal nitrate solutions in the midst of citric acid as catalyst. Synthesis of materials is confirmed using XRD from the report of single phase polycrystalline ferrite material. The magnetic properties of Zn-ferri...
