Recently I have read few papers that developed techniques to measure surface tension at high temperature and pressure. The techniques they have utilized is bubble pressure technique (Published in chemical engineering data) and pendant drop technique (Published in Fuel). I have contacted both authors if I can use their facility to measure some data as the editor will accept my paper once I have shown the experimental data. But none of them have replied. So I would like to know if any of you know which lab or university has the similar facility so I can contact them to measure the surface tension in high temperature and pressure.
