History

Solvothermal and hydrothermal research have attracted the attention of many active researchers because of their advantages in the processing of nanostructured materials and their wide variety of technological applications. 

At the Joint Meeting of the 8th International Symposium on Hydrothermal Reactions

(ISHR) and 7th International Conference on Solvothermal Reactions (ICSTR) in Sendai in August 2006 it was decided that a new international association would be formed.

ISHR and ICSTR would be joined into one big association namely International Solvothermal

and Hydrothermal Association (ISHA). 

The 1st ISHA meeting was held in Nottingham (September 2008), followed by 2nd Beijing (September 2010), 3rd Austin (Jan 2013), 4th Bordeaux (Oct 2014), 5th Taiwan (January 2016), 6th Sendai (Aug 2018), 7th Online (Oct 2021), and 8th Valladolid (Sep 2023). The 9th ISHA2025 conference was held in Bali (June 2025) as a joint conference with ISSF (International Symposium on Supercritical Fluids). 

The aim of this Joint event was to offer an opportunity for researchers from all over the world to exchange scientific ideas and to promote the basic and applied aspects of

research in hydrothermal and solvothermal technology. 

The Next Meetings

The 10th ISHA meeting will be held in 2027.
