RESEARCH SUMMARY 

Dr. Duarte has more than 25 years research experience in Thermodynamics.  He has measured PVT and heat capacity of new alternative refrigerants. During his tenure at Union Carbide Corporation/Dow Chemical, he measured a wide variety of physical properties of industrially important chemicals (measurements of VLE, LLE, SLE, solubility of gases in liquids, solubility of gases in polymers, and diffusion coefficient of gases in polymers). He developed a technique to measure the solubility and diffusion coefficient of gases and vapors in polymers using a magnetic suspension balance. As a professor, he has directed more than 40 master’s research projects at Texas A&M University – Kingsville.
