On thermodynamic stability conditions for nanosized particles

On applicability of Gibbs thermodynamics to nanoparticles

“…Analyzing the method used in this paper, a conclusion can be made that the characteristic radius R c corresponds to the correlation sphere radius in the bulk maternal phase. The conclusion agrees with our theoretical results on stability conditions for nanoparticles [21] as well as with the results laboratory [22] and computer [23] experiments. Presumably, R = R c corresponds to a speci¯c phase transition when the two-phase heterogeneous system (R > R c ) is transformed into a thermodynamically homogeneous system containing micro-heterogeneities of very small radii R < R c .…”

On the size dependence of surface tension in the temperature range from melting point to critical point

“…For droplets consisting of aspherical molecules (such as higher alcanes) we used the RISM-model which suggests that fragments of molecules (e.g. groups −CH 2 − and −CH 3 ) be interpreted as structural units instead of whole molecules [6]. However, the form of the σ (R) dependence is not sensitive to the choice of the pair potential and the shape of molecules.…”

“…The interest to thermodynamics of small objects has greatly increased in view of rapid development of nanoscience and nanotechnology. In fact, the thermodynamic method shows great promise in predicting nanoparticle stability or instability [6,7].…”

The Investigation of the Influence of Point Defects on the Thermodynamic and Structural Properties of Nanocompacted Cobalt and Copper

“…В данном случае скорее можно вести речь о термической стабильности нанокластера [9,10], хотя нельзя исключать и влияние механизма потери механической стабильности, который связан с флуктуациями объема частицы и определяется балансом между объемной упругой энергией, характеризующейся изотермической сжимаемостью массивной материнской фазы, и поверхностной энергией [11].…”
