“…As can be seen in Figure 10, fully dense samples with improved mechanical properties were achieved at comparatively lower sintering temperatures by using SPS 66 . The effectiveness of SPS is not only that samples are fully densified, but also that CNTs are retained in the 20 composites.…”

“…Balazsi et al 66 compared the effectiveness of SPS to conventional hot isostatic pressing for silicon nitride composites reinforced with 6 wt.% MWNTs. As can be seen in Figure 10, fully dense samples with improved mechanical properties were achieved at comparatively lower sintering temperatures by using SPS 66 .…”

“…Modulus of elasticity of composites as a function of apparent density for Si 3 N 4 composites containing 6wt.% MWNT produced by hot-isostatic press sintering and spark plasma sintering 66 . The results clearly indicate that spark plasma sintering produces highly dense composites leading to at least 100% increase in modulus of elasticity (Permission to published these images has been requested) …”

Ceramic matrix composites containing carbon nanotubes

Due to the remarkable physical and mechanical properties of individual, perfect carbon nanotubes (CNTs), they are considered to be one of the most promising new reinforcements for structural composites. Their impressive electrical and thermal properties also suggest opportunities for multifunctional applications. In the context of inorganic matrix composites, researchers have particularly focussed on CNTs as toughening elements to overcome the intrinsic brittleness of the ceramic or glass material. Although there are now a number of studies published in the literature, these inorganic systems have received much less attention than CNT/polymer matrix composites. This paper reviews the current status of the research and development of CNT-loaded ceramic matrix composite materials. It includes a summary of the key issues related to the optimisation of CNT-based composites, with particular reference to brittle matrices and provides an overview of the processing techniques developed to 2 optimise dispersion quality, interfaces and density. The properties of the various composite systems are discussed, with an emphasis on toughness; a comprehensive comparative summary is provided, together with a discussion of the possible toughening mechanism that may operate. Lastly, a range of potential applications are discussed, concluding with a discussion of the scope for future developments in the field.3

“…The peaks of the characteristic prompt gamma ray are demonstrated on a continuous energy spectrum. If the discrimination of the prompt gamma ray peak is applied to the non-destructive inspection, although the components of the target material were not previously identified, the target can be estimated without using a chemical component test or the destructive techniques [2][3][4][5]. Thus, this prompt gamma ray activation analysis (PGAA) method can be applied to detect explosives and drugs in an airport or a harbor [6,7].…”

The purpose of this research is a statistical analysis for discrimination of prompt gamma ray peak induced by the 14.1 MeV neutron particles from spectra using Monte Carlo simulation. For the simulation, the information of 18 detector materials was used to simulate spectra by the neutron capture reaction. The discrimination of nine prompt gamma ray peaks from the simulation of each detector material was performed. We presented the several comparison indexes of energy resolution performance depending on the detector material using the simulation and statistics for the prompt gamma activation analysis.

“…[26]. CNTs have been proved an efficient heterogeneous nucleating agents that can accelerate the crystallization of several inorganic materials, including cement, silicon nitride and zirconium oxide [27][28][29]. The effect of pristine and functionalized single-walled CNT (SWCNT) and multi-walled CNT (MWCNT) on CaCO 3 mineralization has been also investigated.…”

Abstract:In our crystallization experiments, the influence of alginate from Chilean Lessonia nigrescens and functionalized multi-walled carbon nanotubes (MWCNTs) was tested through electrocrystallization (EC) and gas diffusion (GD) methods on the crystal growth of calcium carbonate (CaCO 3 ) and their possible stabilization of proto-structures in amorphous CaCO 3 (ACC) state through pre-nucleation clusters (PNC) essays with automatic potentiometric titrations were performed. CaCO 3 crystals obtained in the in vitro above-mentioned crystallization systems were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectrometry (EDS) and powder X-ray diffractometer (XRD). Our experimental findings showed that ALG and functionalized MWCNTs stabilized truncated and agglomerated vaterite-like particles through GD and EC methods. While, on the other hand, we obtained qualitative information about induction or inhibition of CaCO 3 nucleation that was provided by potentiometric titrations.
