form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. 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. Diatomic oxygen gas constitutes 20.9% of the volume of ...
Cells lacking wild-type VHL or in which EGLN3 is inactivated have reduced mitochondrial mass. Tumorigenic VHL variants leading to different clinical manifestations fail to bind hydroxylated TFAM. In contrast, cells harbouring the Chuvash polycythaemia VHLR200W mutation, involved in hypoxia-sensing ...
·6H2O (Sigma, ≥ 99.0 %) and Fe(NO3)3·9H2O (Sigma, ≥ 99.95 %) were dissolved into de-ionized water with vigorous stirring until a transparent solution was formed, followed by addition of known mass of citric acid (Sigma, ≥ 99.5 %) and ammonia-dissolved ethylenediamine...
While GOLD and several other remote sensing data sets show a similar relationship with solar activity, the empirical data-driven model MSIS 2.0 (Mass Spectrometer Incoherent Scatter radar) overestimates the response of molecular oxygen density to solar forcing, most notably at low solar activity. ...

Definition The most abundant elementon earth, making up about 47% of the earth’s mass,and essential for respiration. General Description Oxygen is a colorless, odorless and tasteless gas. Oxygen will support life. Oxygen is noncombustible, but will actively support the burning of combustible mate...
Transition metal chalcogenides (TMChs) have a general formula of MxXz, in which M is the metal element and X is the chalcogen element (X = S, Se, Te). Monochalcogenide MX, dichalcogenide MX2, heazlewoodite M3X2, and pentlandite M9X8 are the most common stoichiometries of TMCh...
We quantified the mass loss of SGO related to surface oxygen vacancy formation by thermogravimetric analysis. As depicted in Supplementary Fig. 28, SGO exhibits weight loss during heating, while the weight of SO remains relatively constant in a nitrogen environment. The weight loss of SGO is appro...
