The previous ISHR meetings were held in Japan (1982), USA (1985), Russia (1989), France (1993), USA (1997), Japan (2000) and China (2003), with the concept of bringing together scientists involved in various aspects of high-pressure/temperature research in different solvent media including aqueous solutions. The previous ICSTR meetings were held in Japan (1994 and 1996), France (1999), Japan (2000), USA (2002) and India (2004), with a focus on the reactions in a variety of solvent media including aqueous solutions. The joint meeting of ISHR-7 and ICSTR-6 was first held in Kochi, Japan (2000).
In 2006, the International Solvothermal and Hydrothermal Association (ISHA) was established and the Joint meeting of the ISHR-8 and ICSTR-7 was held in Sendai, Japan, which brought a large number of scientists from all over the world to share the common interests in the fields. In 2008, the first ISHA International Conference was held at the University of Nottingham, UK. The second conference was held in Beijing in 2010 (China) and the third one in Austin (Texas, USA) in 2013.
ISHA 2014 will be held in Bordeaux (France).
