If the two rooms are too closed to each other, and if you're using just natural diffusion (which is REALLY slow), it'll cause overpressure faster and each electrolyzer will have a longer down time. Same goes if you have multiple electrolyzers in the same room. It's all about having ...
better to go with slightly lower yield per electrolyzer and perfect hydrogen production than the opposite as the amount of used water and power is directly proportional to amount of produced oxygen regardless of the setup - electrolyzer delays caused by overpressure stop both water and power use. ...
75), these encounter rates would support in situ rates between 3 and 30 nmol L−1 day−1, which is in line with the measured rates (Table1). It is likely that this is a conservative estimate as the encounter model assumes that anammox bacteria are not motile76,77, which limi...
The anaerobic samples (produced by blowing N2 over the liquid–air surface for ∼30 min, and leaving a slight N2-overpressure) are yellow, and were loaded in glass syringes (with greased stems to prevent oxygen from entering the solution) and consequently illuminated outside the apparatus ...
To ensure low O2 levels during ischemia, the ischemic solution was continuously bubbled with nitrogen, and the perfusion chamber covered with parafilm and gassed with nitrogen with a slight overpressure. This was to prevent the diffusion of O2 into the solution in the chamber. O2 levels at 1–...
Under a slight overpressure, water was dispensed into 12 ml exetainers (Labco, Lampeter, Ceredigion, UK) either directly or through helium-flushed inline filter holders, and immediately capped with deoxygen- ated lids. Rates were measured for two biomass fractions: bulk water containing all ...
the water was degassed with helium for 15 min. The water was dispensed into 160 mL glass serum bottles using a helium overpressure through an inline 47 mm diameter filter holder (PALL, USA) which was flushed with helium to avoid oxygen contamination. For bulk water samples, no filter...

The lipid monolayer surrounding the gas phase provides a Laplace overpressure (which favors diffusion of gas out of the particle), and prevents a direct blood-gas interface (which prevents blood trauma). Their small size optimizes the surface area volume ratio, creating a large surface area for...
