The absorption of 25 wt% and 50 wt% glycerol in water is measured at least three times on the same Al2O3 plate and the results are presented in Fig. 9. The bars in Fig. 9 indicate the standard deviation in the measurement series. The spread in the results equals 10%, which ...
Thismethod is also known as the porous plate technique. The only disadvantage with this method is that itis time consuming caused by the low flux through the diaphragm (porous plate).In this paper we present drainage capillary pressure curves and resistivity index measured on reservoirrock samples...
10(c)) showed almost the same electrochemical active surface area within the measurement error range, suggesting that Pd may be able to replace Pt as an electrocatalyst in PEMEC. Sign in to download hi-res image Fig. 10. (a) The images of platinum particles deposited on GNFs (a1) and ...
In this contribution, we develop a microfluidic setup that allows for the simultaneous measurement of the inlet pressure during immiscible displacement within 2D PDMS porous-like domains at extremely high accuracy (i.e.\(\pm 20 {\rm Pa}\)which is sufficient for resolving both capillary and visco...

The filtration pressure at which water flux was measured was 2 kg/cm2. The filtration pressure at which rejection was measured was 0.5 kg/cm2. The filtration temperature was 25° C. for both measurements. The measurement was made 5 minutes after the beginning of filtration. The water flux ...
However, the measurement of surface energies (𝛾𝑠𝑣 and 𝛾𝑠𝑙γsv and γsl) is difficult to perform. Therefore, surface energy modeling approaches can be used. The most widely known surface energy estimation approaches are Owens, Wendt, Rabel, and Kaelble (OWRK) [58], van Oss,...
The data as to thickness for some membranes were again omitted where lateral striations made meaningful measurement difficult. The column for normalized flow reports a calculated figure, which is the rate of water flow through the membrane tested, but calculated to a thickness of 100 micrometers. ...
We conducted variable-humidity (VH) and variable-temperature (VT) PXRD measurement withVPC-1to evaluate the detailed structural change upon H2O sorption. The VH-PXRD patterns at 22.6 °C exhibited an abrupt and reversible enhancement/attenuation of the peak area upon increasing and decreasing th...
