So, when the NO2-PM reaction becomes less effective as relatively little NO2 can be generated by the system, the O2-PM reaction takes over. In addition, when the engine is generating the exhaust temperatures of about 500 °C, and the engine-out NOx level is very high, even a 20% ...
A wet process for oxidation-absorption of nitric oxide by persulfate/calcium peroxide This study develops and evaluates a novel wet method for NO removal using a Na2S2O8/CaO2 solution. The effects of these two components both and alone in so... Z Wang,Y Zhang,Z Tan,... - 《Chemical Engi...
Oxy-fuel combustion is the most effective technology in CO2 emission control.The mercury speciation in oxy-combustion flue gas,especially the influence of high content H2 O and CO2 on the chemical reactions among the flue gas oxidative components(SO3,SO2,NO,NO2,HCl,O2,CO),as well as the in...
(iii) Ozone being an electrophilic agent can attack the nucleophilic position of the organic substances and the group in the aromatic molecule, such as -OH−, -NO2−and –Cl has a significant influence on the reactivity of the aromatic ring with ozone. (iv) Ozone demonstrates nucleophilic...
In particular, stress induced leakage current (SILC) characteristics showed that the generation of defect states can be dramatically suppressed in metal oxide semiconductor (MOS) structures with plasma-assisted oxide layer due to the formation of stable Si-O bonds and the reduced concentrations of ...
Kyoko Arimoto-Matsuzaki1, Haruo Saito1 & Mutsuhiro Takekawa2 Cytoplasmic stress granules (SGs) are multimolecular aggregates of stalled translation pre-initiation complexes that prevent the accumulation of misfolded proteins, and that are formed in response to certain types of stress including ER stress...
The solid electrolyte 12CaO·7Al 2O 3 (C12A7) is an interesting material where an atomic oxygen radical anion (O ) can be emitted from the C12A7 to vacuum when it is heated to 1000K under an applied electric field (100V/cm). However, the mechanical strength of the C12A7 is not...
1985). For the VOCs removal catalysts, the mesopore should be more beneficial to the adsorption of VOCs molecules. Typical mesoporous materials include SBA-15, carbon nanotubes, clays, and some man-made mesoporous metal oxides such as MnO2, Co3O4, CeO2, and CeMnO x (Sanchis et al. 2018...
aberration-corrected TEM image of Os/CNS was shown in Fig.1d. It is obvious that no large nanoparticles were observed. The evident lattice stripe of CNS support revealed its good crystallinity, which indicated a superior electronic conductivity. The inset of Fig.1dcorresponded to the selected area...
Such an interest is caused by features of NMs’ structure and morphology, where at least half atoms of an individual particle are on or near the surface, ready for adsorption and interaction with outer molecules. There is no surprise that various NMs are widely used for heterogeneous catalysts ...
