Using cavitation to break down invisible water pollutants
Researchers from the Faculty of Mechanical Engineering and the National Institute of Chemistry conducted an experimental study in which they achieved the degradation of a water-soluble synthetic polymer - poly(vinyl alcohol) PVOH - by acoustic and hydrodynamic cavitation. The use of PVOH is rapidly increasing, and as a result, increasing amounts of this material are being released into the environment. PVOH is widely used in the textile and paper industries, as well as in households, for example in the form of detergent pods. It is estimated that thousands of tons of it are washed into the aquatic ecosystem every year.

The innovative solutions for the use of flexibility in the power system
The increasing share of renewable distributed energy resources (DERs) in the power system is becoming a key for the decarbonization of the European energy sector and thus achieving the EU's energy and climate change policy objectives. The variability and uncertainty of the DERs generation present significant risks and challenges related to the stability and reliability of the entire interconnected European power system, as well as national and even small local networks while opening new opportunities for the development of new energy concepts and solutions.

A controlled experiment tests the effectiveness of knowledge transfer in Slovenian agriculture for the first time
With agriculture accounting for around 10% of greenhouse gas emissions in the European Union, and with cattle farming contributing the largest share, there is an urgent need to increase the uptake of low-emission farming practices in this sector. Education and good advisory support play an important role in promoting such changes, enabling farmers to acquire new knowledge and change their attitudes towards this issue.
