The model couples Langmuir adsorption kinetics with geometric concentration and mechanical equilibrium. A sharp jamming boundary exists in the (Langmuir affinity, desorption rate) plane; commercial butyl and isobutyl xanthates lie deep inside the jammed region at typical flotation dosages (Monte-Carlo probability 1.00). Hysteresis energy spans 10−14 to 10−9 J, and the critical bulk concentration for jamming ranges from 8.2 · 10−6 to 0.35 mol m−3. The boundary shifts predictably with bulk concentration, pressure, and cycle time, but is insensitive to the shell modulus. Numerical convergence is confirmed, and a one-cycle divergence exponent peaks at +0.42 s−1 near the transition. The model provides a predictive tool for surfactant-stabilised nanobubbles across flotation, catalysis, and biomedical nanosystems.</p></abstract><trans-abstract xml:lang="ru"><p>Представлена минимальная 0D кинетическая модель для межфазного заклинивания нанопузырьков, стабилизированных поверхностно-активными веществами. Модель связывает кинетику адсорбции Лангмюра с геометрической концентрацией и механическим равновесием. В плоскости (сродство Лангмюра, скорость десорбции) существует резкая граница заклинивания; коммерческие бутиловые и изобутиловые ксантаты находятся глубоко внутри заклиненной области при типичных дозах флотации (вероятность Монте-Карло 1,00). Энергия гистерезиса составляет от 10−14 до 10−9 Дж, а критическая объемная концентрация для заклинивания колеблется от 8.2 × 10−6 до 0.35 моль·м−3. Граница предсказуемо смещается в зависимости от объемной концентрации, давления и времени цикла, но нечувствительна к модулю оболочки. Подтверждена численная сходимость, а показатель расходимости за один цикл достигает пика при +0.42 с−1 вблизи перехода. Модель представляет собой инструмент прогнозирования для нанопузырьков, стабилизированных поверхностно-активными веществами, в процессах флотации, катализа и биомедицинских наносистем.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нанопузырьки</kwd><kwd>межфазное заклинивание</kwd><kwd>гистерезис</kwd><kwd>кинетика Лангмюра</kwd><kwd>флотация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanobubbles</kwd><kwd>interfacial jamming</kwd><kwd>hysteresis</kwd><kwd>Langmuir kinetics</kwd><kwd>flotation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors thank N.H.
