pHsidonnainen
pHsidonnainen is a fictional metric proposed in discussions of pH-responsive materials and polyelectrolyte networks. It serves as a composite parameter that attempts to quantify how proton activity (as represented by pH) interacts with binding or cross-linking events within a material. The term combines the chemical concept of pH with “sidonnainen,” a coined root intended to evoke bonding interactions.
The concept was introduced in a hypothetical framework by researchers exploring the interplay between acid–base chemistry
Calculation and interpretation
In simple form, pHsidonnainen can be described as a function of normalized proton activity and a binding
It is used in theoretical modeling of pH-responsive hydrogels, in pedagogical materials to illustrate coupled phenomena,
