Scientists at the University of Science and Technology of China in Hefei led the research. The team explored whether an AI robot could use materials found on Mars to produce catalysts to break down water and release oxygen. A catalyst is a substance that permits certain chemical reactions to ha...

They are also dynamic places that redistribute heat and other forms of energy. On...
In the simplest model the defect may be regarded as a non-linear symmetric Ge2O quasi-molecule, with vibration modes as shown in Figure 4.1 [1]. The mode labels as given in the figure will be used throughout this chapter, even if the true form of the modes may be somewhat different ...
Although culture systems present maximal oxygen concentrations of approximately 0.2 mmol O2 l−1, the blood of a healthy adult man can carry up to 9.5 mmol O2 L−1 due to the capacity of the blood protein hemoglobin to form four reversible bonds per molecule with oxygen (reference 23 in...
Oxygen is the third most abundant element in the universe by mass, after hydrogen and helium, and the most abundant element by mass in the Earth’s crust. Dioxygen as a gas makes up 20.9% of the volume of Earth’s atmosphere and is also present in the form of water vapor and CO2. ...
It is able to generate oxygen in normal when malfunction happens to main control system. Energy Efficiency Equipped with unique energy-saving standby technology, oxygen concentration could reach national standard in 3 mins and oxygen production rate increase by 50%. ...
The oxygen reduction reaction (ORR) is an electrochemical process of the utmost importance in energy conversion and storage, corrosion and chemical technologies. The ORR plays a major role in biological processes (such as respiratory biochemical chain reactions) and is being incorporated into numerous ...

In the process of H2S decomposition, *HS is the key intermediate to form S*. In terms of reaction kinetics, oxygen vacancy does not favor the creation of S*, but in terms of thermodynamics, it is favorable. Similarly, S* is the key intermediate in the formation of HgS. Although O-...
