2533. Air quality and climate change - how smart can the cities be?Griša Močnik, Matevž Lenarčič, 2020, unpublished invited conference lecture Abstract: What starts as an air quality problem in urban areas, ends up as a climate change problem globally. Emissions from cities and the power generating facilities powering the cities have local, regional and global effects. We show examples spanning these scales with very practical advice on how to start abatement locally.
Keywords: air quality, climate change, black carbon, aerosol, co2, smart city

2534. OBJECTIVE AND PERCEIVED ENVIRONMENTAL QUALITY IN THE TOWNS OF ZENICA AND MARIBOR : GROUP PROJECT FINAL REPORTIvana Pandža, Katja Belec, Matjaž Žvokelj, Merima Vrškić, Tajda Huber, Ula Urbas, 2020, treatise, preliminary study, study Abstract: In this study, we measured the concentrations of specific heavy metals in the soil and sediment samples taken on different locations of the cities of Maribor (Slovenia), and Zenica (Bosnia and Herzegovina). The report also includes a questionnaire regarding the residents’ views about the environmental quality of the city they live in.
Keywords: Soil, sediments, heavy metals, AAS, pollution, questionnaire, environmental quality.

2540. Photoelectric effect with a twistGiovanni De Ninno, Jonas Wätzel, Primož Rebernik Ribič, Enrico Allaria, Marcello Coreno, Miltcho B. Danailov, Christian David, Alexander Demidovich, Michele Di Fraia, Luca Giannessi, Klaus Hansen, Špela Krušič, Michele Manfredda, Micheal Meyer, Andrej Mihelič, Najmeh Mirian, Oksana Plekan, Barbara Ressel, Benedikt Rösner, Alberto Simoncig, Simone Spampinati, Janez Štupar, Matjaž Žitnik, Marco Zangrando, Carlo Callegari, Jamal Berakdar, 2020, original scientific article Abstract: Photons have fixed spin and unbounded orbital angular momentum (OAM). While the former is manifested in the polarization of light, the latter corresponds to the spatial phase distribution of its wavefront1. The distinctive way in which the photon spin dictates the electron motion upon light– matter interaction is the basis for numerous well-established spectroscopies. By contrast, imprinting OAM on a mat- ter wave, specifically on a propagating electron, is gener- ally considered very challenging and the anticipated effect undetectable2. In refs. 3,4, the authors provided evidence of OAM-dependent absorption of light by a bound electron. Here, we seek to observe an OAM-dependent dichroic photo- electric effect, using a sample of He atoms. Surprisingly, we find that the OAM of an optical field can be imprinted coher- ently onto a propagating electron wave. Our results reveal new aspects of light–matter interaction and point to a new kind of single-photon electron spectroscopy.
Keywords: FEL, OAM, Photoelectric effect
