1. Načrtovanje in izgradnja spletne aplikacije za lokalizacijo polnilnic za električna vozila : diplomsko deloNikola Kurdumanović, 2024, undergraduate thesis Abstract: Z naraščajočo uporabo električne mobilnosti se povečuje potreba po učinkoviti polnilni infrastrukturi za električna vozila. V diplomskem delu raziskujemo področje vse večje uporabe spletnih in mobilnih aplikacij za lokalizacijo polnilnih postaj za električna vozila, in sicer tako v svetu kot v Sloveniji. Opisani so principi razvoja in implementacije tovrstnih spletnih aplikacij s poudarkom na uporabi različnih tehnologij, kot so: JavaScript, HTML (ang. HyperText Markup Language), CSS (ang. Cascading Style Sheets) in drugih za ustvarjanje funkcionalnih aplikacijskih komponent. Navdih za raziskavo izhaja iz zanimanja za sodobne tehnologije ob upoštevanju naraščajoče potrebe lastnikov električnih avtomobilov po zanesljivih informacijah o možnih lokacijah polnjenja. V okviru diplomskega dela smo v grobem načrtali in razvili prototip aplikacije, ki omogoča hiter dostop do potrebnih informacij o polnilnih postajah. Rezultati naše raziskave so nam omogočili uvid in boljše razumevanje sodobnih tehnologij ter njihove praktične uporabe.

2. Synthesis of helional by hydrodechlorination reaction in the presence of mono- and bimetallic catalysts supported on aluminaOreste Piccolo, Iztok Arčon, Das Gangadhar, Giuliana Aquilanti, Andrea Prai, Stefano Paganelli, Manuela Facchin, Valentina Beghetto, 2024, original scientific article Abstract: Hydrodechlorination reaction of 3-(benzo-1,3-dioxol-5-yl)-3-chloro-2-methylacrylaldehyde in the presence of different low metal content heterogeneous mono- or bimetallic catalysts was tested for the synthesis of the fragrance Helional® (3-[3,4-methylendioxyphenyl]-2-methyl-propionaldehyde). In particular, mono Pd/Al2O3, Rh/Al2O3 or bimetallic Pd-Cu/Al2O3, Rh-Cu/Al2O3 catalysts were tested in different reaction conditions from which it emerged that mono-Rh/Al2O3 was the best performing catalyst, allowing achievement of 100% substrate conversion and 99% selectivity towards Helional® in 24 h at 80 °C, p(H2) 1.0 MPa in the presence of a base. To establish correlations between atomic structure and catalytic activity, catalysts were characterized by Cu, Rh and Pd K-edge XANES, EXAFS analysis. These characterizations allowed verification that the formation of Pd-Cu alloys and the presence of Cu oxide/hydroxide species on the surface of the Al2O3 support are responsible for the very low catalytic efficiency of bimetallic species tested.

4. A method for quantification of mineral dust in air based on optical absorption of particles concentrated by a virtual impactor and a device performing the said method : SI3783336 (T1), 2024-02-29Luka Drinovec, Griša Močnik, Iasonas Stavroulas, Spiros Bezantakos, Michael Pikridas, Florin Unga, Jean Sciare, 2024, patent Abstract: The present invention belongs to the field of devices and methods for measurement of particle concentration, more precisely to the field of devices and methods for quantification of particles based on their physical characteristics, especially with the use of optical means. The invention relates to a method for determination of ambient mineral dust concentration based on optical absorption of particles concentrated by a virtual impactor as well as a device performing the said method. The method comprises the following steps:- Sampling air samples with particle size smaller than 1 µm (PM1) and sampling air samples with particle size up to 10 µm;- Concentrating the samples with particle sizes up to 10 µm with a virtual impactor;- Measuring optical absorption of collected samples at least one wavelength from UV to IR spectre, preferably from 370 to 950 nm, most preferably at 370 nm;- Subtracting the absorption of the samples with particle size smaller than 1 µm from the absorption of the sample concentrated by the virtual impactor.
