Successful in situ and in-step formation of C-dots composited TiO2 mesocrystals is closely related to the complexation between carbon source and Ti ion.

Carbon Structures

Carbon source precursors for high-grade, clean, and low-carbon refractories were obtained by in situ exfoliation of flake graphite (FG) and phenol–formaldehyde resin (PF) composites with three-roll milling (TRM) for the fabrication of graphite nanoplatelets. In addition, by using Ni(NO3)2·6H2O as a catalyst in the pyrolysis process, multidimensional carbon nanostructures were obtained with coexisting graphite nanoplatelets (GNPs), glassy carbon (GC), and carbon nanotubes (CNTs). The resulting GNPs (exfoliated 16 times) had sizes of 10–30 μm, thicknesses of 30–50 nm, and could be uniformly dispersed in GC from the PF pyrolysis. Moreover, Ni(NO3)2·6H2O played a key role in the formation and growth of CNTs from a catalytic pyrolysis of partial PF with the V–S/tip growth mechanisms. The resulting multidimensional carbon nanostructures with GNPs/GC/CNTs are attributed to the shear force of the TRM process, pyrolysis, and catalytic action of nitrates. This method reduced the production costs of carbon source precursors for low-carbon refractories, and the precursors exhibited excellent performances when fabricated on large scales.

Biological Phosphorus

The microbial communities in activated sludge acclimated with either acetate or glucose as the major carbon source under phosphorus limited or rich conditions were investigated morphologically, phylogenetically and chemotaxonomically. The sludge with a minimized polyphosphate content was dominated by tetrad shaped bacteria, which were suspected to be ‘glycogen accumulating bacteria (GAOs) or G bacteria’ The sludge containing high polyphosphate was dominated by cluster forming coccus bacteria. Quinone analyses suggested that all the sludge tested contained various ubiquinones and menaquinones, of which the ubiquinones Q-8 and Q-10 were dominant. Analyses with rRNA targeted probes showed that beta sub class of Proteobacteria was most predominant in all sludges tested. Morphological, phylogenetic and chemotaxonomic investigation all indicated that both high and low P sludges are microbiologically diverse.

Hybrid Carbon

The in situ TiC/Al-Cu nanocomposites were fabricated in the Al-Ti-C reaction systems with various carbon sources by the combined method of combustion synthesis, hot pressing, and hot extrusion. The carbon sources used in this paper were the pure C black, hybrid carbon source (50 wt.% C black + 50 wt.% CNTs) and pure CNTs. The average sizes of nano-TiC particles range from 67 nm to 239 nm. The TiC/Al-Cu nanocomposites fabricated by the hybrid carbon source showed more homogenously distributed nano-TiC particles, higher tensile strength and hardness, and better abrasive wear resistance than those of the nanocomposites fabricated by pure C black and pure CNTs. As the nano-TiC particles content increased, the tensile strength, hardness, and the abrasive wear resistance of the nanocomposites increased. The 30 vol.% TiC/Al-Cu nanocomposite fabricated by the hybrid carbon source showed the highest yield strength (531 MPa), tensile strength (656 MPa), hardness (331.2 HV), and the best abrasive wear resistance.
