WebFeb 14, 2024 · Figure 6 shows the relationship between nanoparticle size and melting point for gold according to the Gibbs-Thomson equation. As we can see, the melting point of gold nanoparticles can be even lower than room temperature (~23-25 °C) when the size decreases to less than about 1.4 nm. At that size, there are only about 85 atoms present … WebAnd at 500 mN/m, Ga’s surface tension is the largest of any liquid at room temperature; for comparison, water’s surface tension is 72 mN/m, and ethanol’s is 22 mN/m. Thus, in the absence of a surface oxide layer, the metal flows like water due to its low viscosity and naturally forms spherical shapes due to its high surface tension.
