TL;DR: In this article, the authors highlight outstanding issues related with the processing of nanoceramics and ceramic nanocomposites, discuss the novel processing techniques currently used to develop these materials, and critically analyses the property modifications resulting.
Abstract: The recognition that bulk nanoceramic materials, having grain sizes typically 100 nm or finer, possess appealing mechanical, physical and tribological properties has generated considerable recent research activity. A major challenge in the research on bulk nanoceramics and nanoceramic composites is concerned with the aspect of processing, in particular restriction of grain growth during sintering. In this regard novel processing techniques have been developed with the aim of fabricating bulk ceramic nanomaterials. The superior properties exhibited by these bulk nanoceramics and ceramic nanocomposites, compared with conventional ceramic materials, have opened up prospects for their use in applications demanding better mechanical properties. The present review highlights outstanding issues related with the processing of nanoceramics and ceramic nanocomposites, discusses the novel processing techniques currently used to develop these materials, critically analyses the property modifications resulting...

TL;DR: In this article, an adherent thin coating was obtained using the electrophoretic deposition (EPD) technique at 30-V and sintering at 850-C. The microstructure of the coated surfaces was characterized by optical microscopy, AFM, and SEM, and the composition of the coating was examined using EDAX.

TL;DR: In this article, a review examines the fundamental factors underlying nanoceramic sintering and the approaches to effectively utilize these factors to improve the performance of the sintered grains.
Abstract: There are two challenges in nanoceramic sintering: fully densifying the sintered body and maintaining the sintered grains at <100 nm size. This review examines the fundamental factors underlying nanoceramic sintering and the approaches to effectively utilise the sintering factors to advantage. Nanoceramic sintering techniques are divided into four categories: pressureless sintering, pressure sintering, electrically assisted sintering, and other sintering related techniques. Pressureless sintering has mainly evolved around modifying sintering schedules, improving nanoparticle packing characteristics, and using additives to tailor the diffusion rates. Pressure sintering, which includes hot pressing, hot isostatic pressing, and sinter forging, can effectively achieve full densification for nanostructured ceramics but microstructural inhomogeneity and sintered shape limitation are difficult to overcome. For electrically assisted sintering, many nanoceramics have been sintered to full density with spar...

TL;DR: In this article, a solution casting method was used to synthesize polymer nanocomposite (PNC) films based on sodium alginate and polyaniline (SA/PANi) and TiO2 as nanoceramic.
Abstract: Polymer nanocomposite (PNC) films based on sodium alginate and polyaniline (SA/PANi) and TiO2 as nanoceramic were synthesized by solution casting method. XRD displayed that the average size crystalline of the TiO2 NPs is 19 nm, and the amorphuos degree of the SA/PANi blend decreased due to the addition of TiO2 NPs. The interaction between the TiO2 NPs and the SA/PANi blend was confirmed by FT-IR spectroscopy, due to vibrational changes that occurred after the addition of TiO2 dopant in the polymer blend. The UV–Visible spectrum was used to calculate optical energy band gaps (direct and indirect). Both of the Egdi and Egind were reduced with the rise in TiO2 content. Thermogravimetric showed that the thermal stability of the nanocomposite was higher than the pure SA/PANi. With the increase in TiO2 NPs concentrations and frequency, the electrical properties such as dielectric and ac conductivity of pure blend improved and displayed maximum electrical properties (dielectric and conductivity) at 1 wt% loading. Additionally, the doping of TiO2 NPs in the polymer matrix proved that the nanocomposites exhibited excellent antimicrobial activity against all the bacteria taken for the test. It is obvious from the results that the nanocomposites have the potential for use in active packaging applications.
