Irregularities in hydrogen fuel cell catalysts
The increasingly evident consequences of climate change are a major motivation for the development of low-carbon technologies, among which fuel cells, using hydrogen as fuel, hold great promise. One of the obstacles to the wider commercialization of the technology is the use of expensive and rare platinum in catalysts, which is why effort goes into trying to reduce the amount of platinum used while preserving the relevant properties of these materials. For the oxygen reduction reaction, one of the reactions in a fuel cell, we use catalysts with alloyed nanoparticles containing platinum and cheaper transition metals. Since certain defects in the nanoparticle structure can occur during the preparation of the catalyst, the effects of all aspects of the structure on the performance in the fuel cell need to be studied in detail.

The thin line of sheet metal forming
The production of thin-walled components from sheet metal is an integral part of the automotive, aerospace and other industries. Forming the initial sheet metal into the desired final shape of the product requires overcoming reaction forces and thinning of the sheet metal, which can lead to fractures. Knowing the influence of many parameters of the forming process allows controlled change of the shape of the workpiece, thus achieving the target shape of the final component.

Project »FEATURE«: Far-from-Equilibrium ATtractors at Ultra-Relativistic Energies
One of the grand challenges facing the high-energy physics community is understanding the far-from-equilibrium evolution of quantum chromodynamics (QCD). This new postdoctoral Marie Skłodowska-Curie project, carried out at the Faculty of Mathematics and Physics, will take the critical step to bring theoretical understanding to the level of complexity required for realistic phenomenology, by fully characterizing the properties of the QCD attractor without resorting to simplifying assumptions done in the current preliminary studies. This will be done via the inclusion of fermionic degrees of freedom and by relaxing simplifying spatial symmetries.

Treating wastewater through cavitation and understanding the effects of bubbles on bacterial cells
Increasing environmental pollution and drinking water shortages are a growing socioeconomic problem, in which cavitation technology can contribute to a cleaner and greener approach to wastewater treatment. Cavitation is a physical phenomenon that describes the phase change from liquid to vapour and back at constant temperature. The mechanical, thermal and chemical effects of cavitation can be utilised for various purposes, including to inactivate microorganisms in drinking water and wastewater. It has been proven that cells are subjected to damage in the immediate vicinity of a bubble. Further numerical analysis has identified the formation of microjets as a possible mechanism of bacterial cell damage.

Hydrodynamic cavitation can be used to inactivate enveloped viruses
Researchers from the Faculty of Mechanical Engineering at the University of Ljubljana, led by Prof. Dr. Matevž Dular, have shown in an experimental study that the phi6 virus, which belongs to the viruses with a lipid envelope, can be successfully inactivated using hydrodynamic cavitation. The study is significant in that it shows that hydrodynamic cavitation has the potential to inactivate pathogenic enveloped viruses in water under ambient conditions. Although the primary mode of transmission for enveloped viruses is not water, the recent pandemic has reminded us that we need to be prepared for the worst, given the possibility of the emergence of enveloped viruses or virus strains that can be transmitted through water in the future.

A research breakthrough in the dating of historical books
Heritage scientists can now date historical paper using only infrared light and computational analysis of spectroscopic data. In the research of postdoctoral researcher Dr. Floriana Coppola and colleagues, which is published in the top scientific journal 'Journal of the American Chemical Society', shows that it is possible to date paper extremely accurately, even to 2 years. An uncertainty this low is not possible with any other method, much less with a non-destructive method.

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.

Shocking in the field of pressure metrology
Accurate measurements of time-varying pressure are important to many industrial sectors. The most stringent requirements for accurate high-frequency pressure measurements come from the automotive, aerospace and ballistics industries, where pressure with frequencies up to few hundred kHz must be accurately measured. To provide dynamic calibrations of pressure meters in the required frequency range and therefore enable accurate measurements in the most demanding industries, many national metrology institutes worldwide are developing a primary dynamic measurement standard for pressure based on the shock tube. In the shock tube, the calibrated pressure meter can be excited by an almost ideal pressure step change generated by the reflection of the shock wave from the end wall of the shock tube. Such an extremely rapid reflection of the shock wave, in addition to generating the high-frequency pressure, inevitably also excites unwanted mechanical vibrations, which can produce spurious output signals of the pressure meter being calibrated.
