Phase diagram of the copper-oxygen system in the liquid-phase temperature rangeOsterwald, Joerg
The Atlas–Centaur rocket was the first rocket to use the combination of liquid hydrogen/oxygen (LH2/LOX) for propulsion. This rocket’s second stage, Centaur, used the RL10 LH2/LOX rocket engine shown in Figure 1. The RL10 manufactured by Pratt and Whitney was the first engine to use...
Here, r is the intermolecular oxygen–oxygen distance and θ is the smallest among the four angles between the intramolecular O–H and the intermolecular O–O lines. As shown previously19, no ambiguity in the identification of hydrogen bonds remains if the Chandler–Luzar geometric criterion is ...
The value of the stoichiometric ratio depends on the composition of the air and, in particular, the oxygen content, often assumed equal to 23.48%. However, the air composition is not a universally used value. Solid fuels may have the form of a veryfine powder(e.g., aluminum) or a solid...
摘要: On the basis of the analysis of the published data on the phase relations in the Sm-Ba-Cu-O system in air, two possible versions of the liquidus surface of the system are constructed in the entire composition range and the corresponding equations of phase reactions are derived....
(solid line) during the interaction process.fRepresentative configurations of the associated GK-16*; the right panel shows a magnified view of the bidentate H-bonds, green arrows indicating the H-bonds. Atoms in Dopa residues are colored as follows: hydrogen, white; oxygen, red; carbon, cyan...
(ALI; cells access the culture medium only from the basolateral cell side), result in highly differentiated oviduct epithelial cell cultures. The oxygen (O2) tension within the oviduct is 4–10% across species, and its reduced O2content is presumed to be important for early reproductive ...
The proposed loss mechanisms suggest that the oxygen vacancies and the average grain sizes are the influencing factors in the dielectric loss of MTO ceramics. 展开 关键词: Microwave dielectric properties La2O3 and V2O5 additives Microstructure ...
Fluorine and oxygen are powerful oxidizers even in liquid form. Some cryogens are flammable; hydrogen is especially delicate to handle. Hydrogen is an unusual fluid in that the molecule exists in two forms known as ortho and para, with somewhat different properties. The ratio of ortho to para ...
In the case of Ni-additives, the formation of a combination of A-site and oxygen vacancies (which also forms the basis for the charge compensation mechanism for a B-site dopant location in the earlier explanations, Eq. (1)) was shown to be significantly less favourable than the formation ...
