Project An investigation of the mechanisms at the interaction between cavitation bubbles and contaminants
Researcher (PI) Matevz DULAR
Host Institution (HI) UNIVERZA V LJUBLJANI
Call Details Consolidator Grant (CoG), PE8, ERC-2017-COG
Summary A sudden decrease in pressure triggers the formation of vapour and gas bubbles inside a liquid medium (also called cavitation). This leads to many (key) engineering problems: material loss, noise and vibration of hydraulic machinery. On the other hand, cavitation is a potentially a useful phenomenon: the extreme conditions are increasingly used for a wide variety of applications such as surface cleaning, enhanced chemistry, and waste water treatment (bacteria eradication and virus inactivation).
Despite this significant progress a large gap persists between the understanding of the mechanisms that contribute to the effects of cavitation and its application. Although engineers are already commercializing devices that employ cavitation, we are still not able to answer the fundamental question: What precisely are the mechanisms how bubbles can clean, disinfect, kill bacteria and enhance chemical activity? The overall objective of the project is to understand and determine the fundamental physics of the interaction of cavitation bubbles with different contaminants. To address this issue, the CABUM project will investigate the physical background of cavitation from physical, biological and engineering perspective on three complexity scales: i) on single bubble level, ii) on organised and iii) on random bubble clusters, producing a progressive multidisciplinary synergetic effect.
The proposed synergetic approach builds on the PI's preliminary research and employs novel experimental and numerical methodologies, some of which have been developed by the PI and his research group, to explore the physics of cavitation behaviour in interaction with bacteria and viruses.
Understanding the fundamental physical background of cavitation in interaction with contaminants will have a ground-breaking implications in various scientific fields (engineering, chemistry and biology) and will, in the future, enable the exploitation of cavitation in water and soil treatment processes.

Summary The profound advantages of printed photovoltaics (PVs), such as their light weight, mechanical flexibility in addition to the small energy demand, and low cost equipment requirements for roll-to-roll mass production, characterise them as a dominant candidate source for future electrical power. Over the last few years, the discovery of novel solution processed electronic materials and device structures boosted PV power conversion efficiency values. Despite that, power conversion efficiency is not a 'stand-alone' product development target for next generation PVs. Lifetime, cost, flexibility and non-toxicity have to be equally considered, regarding the technological progress of solution processed PVs. The ambit of the Sol-Pro research programme is to re-design solution processed PV components relevant to the above product development targets. Based on this, processing specifications as a function of the electronic material properties will be established and provide valuable input for flexible PV applications. Adjusting the material characteristics and device design is crucial to achieve the proposed high performance PV targets. As a consequence, a number of high-level objectives concerning processing/materials/electrodes/interfaces, relevant to product development targets of next generation solution processed PVs, are aimed for within the proposed ERC programme.
