this is called hydrolysis. Those organic substances that contain polar groups (—OH, —NH2, —COOH, and others) and whose molecular weight is not too high dis-solve in water. Water itself is readily soluble (or mixes well in all proportions) only in a limited number of organic solvents. ...

Substances that dissolve readily in water are termed hydrophilic. They include ions and polar molecules that attract water molecules through electrical charge effects. Water molecules surround each ion or polar molecule and carry it into solution. 容易溶于水的物质被称为亲水性。它们包括通过电荷效应吸引...
Fresh polar waters stabilized the deep-warm water heating systemover the whole Earthas thermal energy was absorbed by the oceans at low latitudes. Water stores and transports huge quantities of thermal energy, especially if distributed ocean-wide and ocean-deep. Even if transport is very slow, it...
It should be noted that several mechanisms, such as polar or non-polar, might be possible for the transformation of azide to tetrazole 61-63. Nitrile formation does not occur in the present work because of the azide ion's nucleophilic attack on the electron- deficient carbon atom64. Rather,...
This indicates that the light excitation is not the dominant factor for the high selectivity of liquid alcohol. When the solar light intensity was fixed at 365 mW/cm2, as shown in Fig. S5, an increase of reaction temperature leads to not only increased yield but also a significantly varied...

Noteworthy, ikaite also was identified within sea ice, where it might play an important role in the polar carbon cycles (Dieckmann et al., 2008; Dieckmann et al., 2010; Fischer et al., 2013; Geilfus et al., 2013). The discrepancy between frequent occurrence in nature and metastability ...
The sample recovered elastically and retained its original length, which suggests that it had not been subjected to plastic deformation during the entire experiment. The compressional wave velocities are plotted against pressure in Figure 3 and against temperature in Figure 4. Figure 3 Plot of the ...
