5. In addition, we have measured the evolved gaseous O2 and H2 and the measured FEs are shows in Supplementary Fig. 6. The figure shows that the sum of the FE (O2) and FE (H2O2) is about 98–103%, confirming the accuracy in our H2O2 concentration measurement. Finally, the ...

Again, the pathway of V9+ HER demonstrates the importance of the presence of three V atoms, two of which form a V–O–V bridge in the H2VnO+ intermediate and the third provides the hydrogen receptor and the H2 removal site. Similar to the reaction paths of “\({\mathrm{V}}_5^ +...
The definition: Odor means the sensation(知觉) that results when olfactory receptors(嗅觉受体) in the nose are stimulated by particular chemicals in gaseous(气体的) form. The measurement: It can be measured by sensory(感觉的) methods, and specific odorant concentrations can be measured by instrume...

The large release of energy (latent heat of condensation) as water changes from the gaseous to the liquid state is the key to steam's sterilization efficacy and its efficiency, in general, as a heat transfer agent. If this phase change (condensation) is not allowed to happen because the ...
A volume of gas hydrate expands between 150- and 180-fold when released in gaseous form at standard pressure and temperature (1 kPa, 208 °C [688 °F]). Clathrate hydrates can form in the presence of gas molecules that range from 0.48 to 0.90 nm in size. Three distinct structural types...

In general, superhydrophobic surfaces could obtain OH─ from the nucleated droplet. When the droplet quickly jumps from the surface, it usually holds H+26. However, this phenomenon disappears due to form a counter electric field when the droplet is removed slowly. In this work, we fabricated ...
