The synthesis of zirconia nanomaterials by a one-step sol-gel route under supercritical C02(l) drying using zirconium alkoxides and acetic acid was reported by Sui et al. [24]. Their materials exhibited high surface areas (up to 399 m /g) and porosity, while the calcined materials demonstrated tetragonal and/or monoclinic nanocrystallites. Either a translucent or opaque monolith was obtained. Investigation by electron microscopy showed that the translucent monolithic Z1O2 exhibited a well-defined mesoporous structure, while the opaque monolith, formed using added alcohol as a co-solvent, was composed of loosely compacted nanospherical particles with a diameter of approximately 20 nm. 

ABSTRACT Polymer binder modification of polymer mortars with inorganic nanomaterials could be a potential and efficient solution to control matrix flammability of these materials without scarifying other important properties. However, the incorporation of nanomaterials into polymer mortar materials can expose workers and final users to new risks. This research work aims to evaluate the risk in the polymer mortar production with nano-zirconia, focusing on exposure to the NP in a known research laboratory. In order to obtain exposure data control, air particle measurements were made with a Dust-Trak TM Aerosol Monitor (1 pm nozzle). Maximum concentration was observed in the cleaning task (0,195 mg m ). Future challenges relative to nanomaterials exposure prevention and control should focus on the development and use of more sensitive and specific equipment, devices and measurement methods.

The chapter incorporates a comprehensive overview of the synthesis and use of zirconia nanomaterials in the Hfe sciences today. First, an overview is provided of the synthetic schemes for nanoparticles and anisotropic nanostructures, with the most frequently used strategies being discussed, together with examples. In general, the syntheses are described with no specific application in mind rather, the discussion will center on synthetic approaches for nanomaterials used in biomedical applications, or which may be further processed to materials capable of use in the life sciences. 

During the two decades that have passed since the above-described studies were conducted, the synthesis of nanomaterials has attracted enormous attenhon, and the synthesis of nanostructured zirconia has become a focus of research. Whereas, during the early days research into nanoscale particles was carried out mainly by those achve in the field of ceramics, today the major inveshgahons into nanostruc-...
