This contribution presents the results of structural and compressive strength investigations on cured and high-temperature treated silica-based one-part geopolymer-zeolite composites.
Removing the residual metal in carbon nanofibers does not evidently influence the catalytic behavior whereas the lower conversion of ethylbenzene can be observed on the high-temperature treated carbon nanofiber samples.
Trace amounts of edge sites in natural graphite, synthetic graphite and high-temperature treated coke are quantitatively analyzed from the numbers of hydrogen atoms and oxygen-containing functional groups at carbon edge sites.
The decomposition of PEG during high temperature treating is considered to be responsible for the generation of porous structure in the films as compared with TiO2 film without addition of the polymer, and higher molecular weight leads to larger pore size and specific surface area.
This paper proposes a thermal conductivity model for gypsum at high temperatures, treating gypsum as a porous material consisting of solid and pores and takes into consideration the effects of radiation at high temperatures.
The high pressure and high temperature treated samples were examined by X-ray diffraction, transmission electron microscope, and Raman measurements.
The main reason for the low the turn-on and threshold fields, large current density of high temperature treated SnO2nanowires in oxygen can be probably attributed to the following factors: the high crystalline structure and the reduction of the oxygen vacancy concentration.
Furthermore, novel high-performance carbonized PF/2 wt% MWCNTs/Fe3O4 composite foams (C-PFC2Fs, carbon foam) with open-cell structure were fabricated by using high-temperature heat treating method.
Similar CNT growth is found on the pristine and high-temperature (1350 °C) treated particles under the experimental conditions used.
Carbon nano onions (CNOs) with diameters of 70 100 nm were fabricated by chemical vapor deposition at 800 °C, using methane as carbon source and high-temperature steam treated 316 stainless steel mesh as catalyst.
In assessing the high temperature ammonia treated samples, it is clear that they are generally less digestible than the low temperature ammonia treated and NaOH treated samples.
