Question. H2S is more acidic than H2O because B(a)oxygen is more electronegative than sulphur.(b) atomic number of Sulphur is higher than oxygen.(c) H -S bond dissociation energy is less as compared to H -O bond.(d) H -O bond dissociation energy is less also compared to H - S bo...
Conclusions The reason could be assigned to the suitable acidic and alkaline strength and quantity distributions on the surface of Cluster Al2O3. Meanwhile, smaller-particle MoS2 has more edge-exposed active sites, whi...
However, in the case of weak acidic conditions (pH < 7.0), the fluo- rescence turn-on signal is marginally lower, which was commonly observed in nucleophilic-reaction probes29–33. To test the biological applicability of the dual-reactable probe 1, we examined whether 1 can be used ...
Moreover, H2S can maintain the redox balance and prevent further apoptosis by dynamic regulation of the NADPH oxidase and antioxidant enzyme systems (Kolupaev et al.2017; Yang et al.2016). H2S facilitates the production of more H2O2by NADPH oxidase through the enhancement of transcription and e...
Moreover, Sargassum fluitans III extracts have already shown effectiveness in inhibiting corrosion on steel in acidic environments exceeding 90%. The interaction between zinc and these chemical species, forming a barrier against corrosive agents, could explain the slowdown in corrosion....
Figure 1 reveals that the Nf-TNPP-film-based OWG sensor is more sensitive and more stable toward EDA and H2S than the TNPP-film-based sensor. This is ascribable to electrostatic interactions between the four -NO2 functional groups on the porphyrin and the -SO3− groups of the Nafion ...
