High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to application-oriented, experimental and theoretical studies on thermophysical properties of matter as well as experimental and modeling solutions for applications where control of thermophysical properties is critical. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids, at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions such as high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology and industrial applications, and book reviews.The journal is listed in JCR (Journal Citation Reports) and SCOPUS.
