Polyamorphous liquids and water’s secrets
Dr. Michal Duška, Laboratory of Electrophysics
A new class of liquids is capturing the attention of scientists for its ability to exist in different forms. What if one clear substance, like water, has this peculiarity? There would be two forms of waters separated by the phase transition, the one we know exists between water and vapor, ending in yet another critical point, the place where the two liquids became one. This phenomenon is provoking the imagination and sparking theoretical as well as experimental research.
Shock wave/boundary layer interaction in turbine blade cascades
Dr. David Šimurda, Laboratory of Internal Flows
Although new ways of producing electricity are implemented on an increasing scale, around 93% of electricity in the Czech Republic is still generated in steam and gas turbine power plants (i.e. mainly in nuclear and coal-fired power plants but also in power plants firing different types of gases, biomass, etc.). Even the slightest increase in turbine efficiency brings great savings, not only economically, but also from the environmental perspective. Higher efficiency of energy conversion means using less fuel to produce the same amount of electricity. Especially for power plants burning fossil fuels and various other biological substances this means that we produce less greenhouse gases, fly ash and other pollutants, not to mention air pollution, negative impacts on the landscape and on the whole environment.
Nanomaterial synthesis by spark discharge with application in hydrogen technologies
Dr. Tomáš Němec, Laboratory of Electrophysics
Just as electric cars are replacing fossil fuel cars today, in the future electric cars will be replaced by hydrogen cars. Technologies are already being developed to manage this transition – one of them in the research programme Efficient Energy Conversion and Storage of Strategy AV21, the strategic initiative of the Czech Academy of Sciences.
