The project entitled “Laboratory for the ultracool preparation of complex oxides“, ULTRACOOL in short, was chosen by the JSI Director’s Council as most prosperous and was granted financial support from the Director’s fund for 2017. The prize winners are Hana Uršič, Mojca Otoničar and Marko Vrabelj. The received financial resources are intended for constructing a new laboratory, equipped for preparation of materials at low temperatures (i.e., at or near room temperature). Two techniques that will enable complex functional materials’ processing at low temperatures and will be implemented and further developed are (1) Aerosol deposition and (2) Cold sintering process.
