    "abstract": "The method for determination the microscopic surface tension $\\sigma(R)$ of\nnanobubbles is developed based on the new elaboration of the positronium bubble\nmodel. In contrast to existing structureless Ps bubble models, our version\ncontains experimentally known molecular characteristics of liquids. The\nrelationship, similar to Tolman\u0027s equation, between $\\sigma(R)$ and the radius\n$R$ of the Ps bubble is derived on a microscopic basis. Numerical values for\n$\\sigma(R)$ are determined for a large number of liquids and liquified gases.\nThe results are in agreement with the theoretical expectations and independent\nevaluations, available in literature.",
