Description	Water has been subject to more studies than any other substance. Yet there are technologically significant regions where its properties are poorly understood. This project focuses primarily on liquid water and solutions of selected salts below the freezing point (supercooled water), and water in nano-droplets. Existing hypotheses include the possibility of phase separation of supercooled water into two liquid phases below the second critical point. Density of supercooled water is only known at 0.1 MPa. Suggested measurements up to 100 MPa will provide first data. A new method and apparatus will be developed. The surface tension of supercooled water and a salt solution will be measured. The surface tension of nano-droplets will be estimated from nucleation experiments. A range of theoretical approaches including phenomenological methods, simplified microscopic models, and molecular simulations, will be used with experimental data to obtain fundamental findings and engineering models. (en) Voda byla předmětem více studií než kterákoli jiná látka. Přesto existují technicky významné oblasti, ve kterých jsou její vlastnosti známy zcela nedostatečně. Tento projekt se zaměřuje předně na kapalnou vodu a roztoky vybraných solí pod bodem mrazu (podchlazená voda) a na vodu v nano-kapkách. Existující hypotézy zahrnují možnost separace podchlazené vody do dvou kapalných fázi pod druhým kritickým bodem. Hustota podchlazené vody je známa pouze při 0.1 MPa. Navržená měření do 100 MPa poskytnou první data. Bude vyvinuta nová metoda a přístroj pro tento experiment. Dále bude proměřeno povrchové napětí podchlazené vody a roztoků solí. Povrchové napětí nano-kapek bude určeno z nukleačních experimentů. Bude použita řada teoretických přístupů, zahrnujících fenomenologické metody, zjednodušené mikroskopické modely a molekulární simulace. Výsledkem budou nové fundamentální poznatky a matematické modely vhodné pro technické aplikace.
