“…The boehmite formula is -AlOOH, which is the precursor of -Al 2 O 3 . This formula has been widely used in composites, ceramic materials, protective coatings, and semiconductors [58][59][60][61][62]. The SDS charges the CNT surface negatively, and the stable sol of boehmite is a positively charged nanoparticle.…”

AbstractNanocarbon materials (carbon nanotubes, graphene, graphene oxide, reduced graphene oxide, etc.) are considered the ideal toughening phase of ceramic matrix composites because of their unique structures and excellent properties. The strengthening and toughening effect of nanocarbon is attributed to several factors, such as their dispersibility in the matrix, interfacial bonding state with the matrix, and structural alteration. In this paper, the development state of nanocarbon-toughened ceramic matrix composites is reviewed based on the preparation methods and basic properties of nanocarbon-reinforced ceramic matrix composites. The assessment is implemented in terms of the influence of the interface bonding condition on the basic properties of ceramic matrix composites and the methods used to improve the interface bonding. Furthermore, the strengthening and toughening mechanisms of nanocarbon-toughened ceramic matrix composites are considered. Moreover, the key problems and perspectives of research work relating to nanocarbon-toughened ceramic matrix composites are highlighted.

This study investigates the effect of core-shell-structured supports prepared with alumina as the core on the CO 2 capture performance of K 2 CO 3 . One main issue in using alumina-basedsupported K 2 CO 3 is the high moisture uptake of the sorbent, which converts active sites of K 2 CO 3 to hydrated by-products with a very low CO 2 capture capacity. To address this issue, the support was shelled with a less hydrophilic material using a core-shell technique. Six core-shell-structured supports were prepared using alumina-based cores (γ-alumina and Boehmite), and TiO 2 , ZrO 2 and SiO 2 shells. K 2 CO 3 was impregnated on each support and tested in a thermogravimetric analyzer over ten cycles. K 2 CO 3 /Boehmite/TiO 2 showed the lowest moisture uptake and the highest surface area, and thus the best CO 2 capture performance. A semi-empirical model was developed using a response surface methodology

Pool boiling heat transfer (BHT) of R-141b on porous Cu coated heating surface was experimentally studied. Porous Cu coating was fabricated on a plain Cu heating surface through a two-stage electrodeposition method. Surface characterization of Cu coating confirmed the successful synthesis of micro/nano-porous Cu coating. Experimental results showed that the Cu coated heating surface introduced a significant enhancement in heat transfer coefficient (HTC) and a great reduction in wall superheat compared to the plain Cu surface. The maximum enhancement in HTC for the Cu coated heating surface was approximately 53% compared to the uncoated heating surface. This is believed to have resulted from the increase in active surface area, nucleation site density and cavitation activity owing to the microporous structure of Cu coating. Obtained results showed that the microporous Cu coated heating surface could be employed in modern heat transfer applications.
