Letter to the EditorA comment on ‘‘pH and the surface tension ofwater’’ (J. K. Beattie, A. M. Djerdjev, A.Gray-Weale, N. Kallay, J. Lützenkirchen, T.Preoc ˇanin, A. Selmani, J. Colloid Interface Sci.422 (2014) 54.)Beattie et al. measured surface tension of water as ...
Solution of pure HULIS in concentrations corresponding to real incipient cloud droplets decreased the surface tension of water by about 30%, and the major decrease occurred within several tens of seconds. In diluted solutions, however, the thermodynamic equilibrium in surface tension was only reached ...
Millimeter-sized 'liquid marbles' can be prepared using the pH-responsive PAaH-SiO2 particles. The 'liquid marble' can be transferred intact onto the surface of a neutral or acidic water pool and exhibit long-term stability. When the pH of the water pool becomes alkaline, the 'liquid marble...
As the surface tension of water is 71.8 mN/m at 20 °C, the change in the pH barely influenced the surface tension of the solution. Thus, the surface tension is not a key factor and has a negligible effect on the CA switching in this system. The super wettability of the as-...
This device, which is fabricated using a one-step electrospinning method, consists of biodegradable polycaprolactone and an anionic surfactant. Intriguingly, not only can the resulting micromotor move autonomously on the surface of water for a long period of time (~40 min) due to the Marangoni ...
Free Essay: pH is usually to measure acidic or basic water is. pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water. There are...
What effect does adding soap to water have on the surface tension of water? What effect did changing the temperature of the water bath have on the diving reflex? Explain how extremes of temperature, pH, and osmotic and hydrostatic pressure limit microbial growth. ...

This step served to improve the consistency of the data collected using the USB spectrometer; however, it was noted that the surface tension at the edges of the PCB holder caused imperfections in the uniform path length that the holder was designed to create. Then, 0.4 V was applied to...
With alternatively adding HCl (pH=5.0) and NaOH (pH=10.0), the surfactant could be reversibly switched between highly asymmetrical HOBAB and approximately symmetrical imine-type double-tail amphiphile because of the breakage and formation of imine bonds. Surface tension experiment showed that the ...
