aAir is the name given to atmosphere used in breathing and photosynthesis. Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. 空气是名字被给用于呼吸和光合作用的大气。 干燥的空气大致包含(由容量) 78.09%...
Light-stimulation enables non-invasive spatiotemporal control over the mechanical properties of the framework, which ultimately leads to pore contraction and subsequent guest release via negative gas adsorption. The complex mechanism of light-gated breathing is established by a series of in situ ...
This study investigated breathing argon/oxygen and 100% oxygen gas mixtures during staged decompression prior to exposure to 3.5 psia.During this study, 40 subjects each completed 3 hypobaric exposures to 3.5 psia for 3 h in a reclined position: (A) a 4-h 25-min 14.7-psia (ground level)...
argon lasers, respectively. Photobleaching was performed using the 561-nm laser for 80 frames at 100% power, targeting ROIs. Three combinations of connexin–Clover (donor, green) and connexin–mRuby2 (acceptor, red) are shown before and after bleaching. Colocalisation is shown in white in the...
Gas flow at the catholyte side was oxygen gas during ORR and argon gas during OER. The anolyte was 1 M Li2S4 + 1 M LiOH and the catholyte was 0.5 M Li2SO4 + 0.1 M H2SO4. With increasing current density, the voltage efficiency decreases since additional contributions to impedance ...
