Surface tensionMolecular areaMethylated and hydroxypropylated cyclodextrins (CDs) are highly efficient mass transfer promoters in biphasic aqueous organometallic processes. The surface tension measurements demonstrated that these CDs adsorb at air–water interface and allowed to determine surface excess of CD ...
the reversed motion of a ring fault, accompanying e.g., inflation and deflation phases of the volcanic system45,46. In the frame of tectonic processes, focal mechanism reversals have been reported more sporadically and generally attributed to stress changes induced by large earthquakes and overshoot...
As you would expect, mercury-xenon lamps produce a compromise, balanced across a wider range of wavelengths.Who invented arc lamps? Photo: The basic concept of the arc lamp. An electric discharge passes between two carbon electrodes, giving off light. Strictly speaking, we use the term arc ...
Explain the concept of conservation of linear and angular momentum and its applications. The image below shows a glass pipe with water flowing inside it. Suppose that you change the material of the pipe from glass to ...
waveforms prone to cycle skipping before calculating the cross-correlation and a time-independent criterion for the comparison of the maximum and the second largest peak (sidelobe maximum, CCslm, corresponding to the largest positive value of the cross-correlation function in the case of anti-...
Explain the concept of surface tension. How does it act like a rubbered sheet? Why does it tend to occupy less surface area? Explain the relation pressure is inversely proportional to velocity. When pressure increases velocity also increases. How is the above relation possible? Explain the ...
Explain how surface tension and viscosity are used to transport water and nutrients in trees. Explain why water is such a good solvent for so many different solutes. Explain how to prepare 1.0 L of isotonic saline, which is a 0.92% NaCl solution. Explain the following statement on the b...
The polarity of a bond is determined by a periodic concept called electronegativity. Electronegativity is an expression of an atom's tendency to attract electrons in a chemical bond. In order to determine the polarity of a bond, you must find the difference in the electronegativies of the atom...
So, when the two layers don’t work as a single unit, the performance and strength of the structure will suffer. So, a bonding agent (also called a bonding adhesive) must be put on the existing concrete surface so that the new concrete will stick. It is also true for fixing floors. ...
The division of the earth’s surface into continents and oceans is a consequence of plate tectonics but a geological paradox exists at continent-ocean boundaries. Continental plate is thicker and lighter than oceanic plate, floating higher on the mantle
