Ultrasonic photoacoustic source from graphene nanocomposite film on polymer substratePublicated: 25.October 2022Researchers from the Laboratory for Laser Techniques (LASTEH) in cooperation with researchers from Jožef Stefan Institute developed a graphene-Polydimethylsiloxane (PDMS) composite on a flexible substrate for the photoacoustic generation of ultrasounds. They investigated in detail the photoacoustic (PA) response of the film when irradiated with a nanosecond pulsed laser, for different graphene concentrations and thicknesses. The results of the research were published in the journal Photoacoustics (IF=9,656).

SPATIALLY SELECTIVE DILUTION IN COMBUSTION PROCESSESPublicated: 14.September 2022Researchers from Laboratory for Internal Combustion Engines (LICeM) published a paper in Journal of Environmental Management (IF=8.9) where they presented a novel concept for control of mixture reactivity in continuous combustion systems (burners, gas turbines). Innovative approach confirms the hypothesis that direct and spatially selective injection of inert and partially inert (CO2) gasses in regions with high heat release rates allows a precise control of temperature and concentration field in combustion chamber.
