is used to differentiate between strong and weak acids. the acid dissociates more as the ka increases. strong acids must therefore dissociate more in water. a weak acid, on the other hand, is less likely to ionise and release a hydrogen ion, leading to a less acidic solution. the acid ...

The stability of the protein increases by salt addition [11], thus showing that electrostatic interactions play an important role in structural stability. In the figure, we have emphasized negatively charged carboxylate groups and positively charged groups as, respectively, red and blue spheres. ...
Currently, the most popular methods of GaN growth are HVPE [25], ammonothermal [26], acidic [27], and Na-flux [28]. The basic method of ammonothermal growth requires the application of pressure in the range of 1 GPa. Crystals of up to 8 inches can be obtained using this method. ...
Ion-complementary self-assembling peptides have been studied in many fields for their distinct advantages, mainly due to their self-assembly properties. However, their shortcomings, such as insufficient specific activity and poor mechanical properties, a
