PURPOSE: To easily obtain a crosslinked hydrophilic copolymer used, e.g. for an adsorbent for a liquid having high surface tension, by using an aqueous alkali for saponifying the surface of a macroporous crosslinked hydrophobic copolymer lattice prepared by the precipitation polymerization of ...
Hydrophobic nanoparticles could achieve stable adhesion on the hydrophobic membranes due to the strong attraction. By adding these two materials to particles, it is possible to create a ''composite particle'' with microbumps and nanobumps similar to those on lotus leaf, and make the surface of ...
have been identified as particularly important dietary contributors to dental caries14. Consumption of sweetened foodstuffs can rapidly increase the concentration of carbohydrates in the oral cavity, leading to a sharp decline in the pH values of biofilm to 4 or even lower15. Research has revealed...
aIn the last week they share their results and see how consistent their predictions were. In addition they suggest the likely features of the active binding site, such as its dimensions and the presence of hydrophobic or hydrophilic regions within the binding pocket 在上星期他们分享他们的结果并且...
The tail of a surfactant molecule is hydrophobic, or not attracted to water. What the hydrophobic end is attracted to is grease and dirt. The head of the surfactant molecule, on the other hand, is hydrophilic -- it's attracted to water [source: Silberberg]. So when a greasy piece of ...
This mechanism enables the translocase to transport a large variety of proteins of different sizes and properties, providing that the substrates are unfolded or can be unfolded at the time of transport [22] (Fig. 2). Recent analysis indicates that a pore ring of SecY hydrophobic residues acts...
Substances that dissolve in water are hydrophilic. This means that they are as strong or stronger than water's cohesive forces. Salt and sugar are both polar, like water, so they dissolve very well in it. Substances that do not dissolve in water are hydrophobic. This is the source of the...
Determine if the compound is ionic or covalent. The ionic compounds are typically composed of metals and nonmetals. The metals, with the exception of hydrogen, are located to the left of the periodic table, and the nonmetals are located on the right side. An example of an ionic compound ...
