Deposition of porphyrin thin films by electrophoresis
Andraž Mavrič, Tina Škorjanc, Mads Nybo Sørensen, Changzhu Wu, Matjaž Valant, 2022, published scientific conference contribution abstract

Abstract: Porphyrins are heterocyclic macrocycles consisting of interconnected pyrrole subunits acting as ligands for metal ions. Metallised metalloporphyrins naturally occur as cofactors in a series of enzymes, acting as active sites for biochemical transformations. Mimicking nature, a variety of functionalized porphyrins have been prepared for different catalytic purposes [1]. These organometallic complexes have isolated metal centers in tailored coordination environments to drive catalytic reactions in homogeneous solutions. The activity and selectivity of isolated metal ions acting as single-atom catalysts are defined by the coordination environment. Depending on the porphyrin structure, the solubility of these macrocycles and their processability in solutions can be altered. While such adjustments to the structure might ease the processability, the catalytic properties might also be altered. Because homogenous catalysis presents challenges with the separation and recyclability of the catalyst, it is common to fix metalloporphyrins into molecular organic frameworks or deposit them onto a substrate. Commonly used deposition techniques face several challenges. For instance, thermal evaporation can cause partial or complete degradation of some thermally-labile functional groups attached to the porphyrins. Similarly, spin coating commonly results in an uneven thickness and uneven morphology of the deposited films. To overcome these difficulties, we present an alternative method for the deposition of porphyrin thin films that is suitable for a wide range of functionalized porphyrins. The electrophoresis can force the molecules to deposit on a conductive substrate such as a metal foil or transparent conductive oxide by applying the electric field generated by a DC power supply. The film thickness can be precisely controlled by changing the voltage value, deposition time, or solution concentration using even a small amount of material [2, 3]. Six different functionalized porphyrin molecules have been successfully deposited onto the copper foil substrate by optimizing key parameters, including applied electric field, the duration of electrophoresis, the size of the copper electrodes, and solvent polarity. To demonstrate the generality of our approach, we have selected a broad range of porphyrins that incorporate the following functional groups: phenyl rings, carboxylic acids, pyridyl rings, methyl benzyl ethers, methyl benzoyl esters, and cobalt (II) metalized macrocycle. The impact of this study extends above catalysis to various applications of porphyrins thin films on conductive substrates such as optoelectronics and sensors.

European Film Co-productions with a Focus on Southeastern Europe
Boris Matić, 2022, master's thesis

Abstract: In this master thesis I shall deal with European film co-productions with an emphasis on the functioning of this form of film production in 6 countries of Southeast Europe. Starting from defining the concept of co-productions and their types, short history, agreements that provide the legal framework for their establishment all the way to sources of funding from European public national and supranational funds, broadcasters and production incentive systems. In other words, in this thesis I explain how this joint production adventure works in Europe, as well as in the surrounding countries where I myself work as a film producer. The starting point of the paper is that the authors and producers hail from countries with low audiovisual capacity, and due to high film production prices and lack of funding sources in these countries, they are almost forced to turn to international co-productions for more ambitious film projects. Through the analysis and production study of Father, I speak about the application of the co-production model in filmmaking and the use of almost all types of available European sources of financial closure, which is a successful example of cooperation between producers and filmmakers and collaborators from several European countries. In the practical part of my master’s thesis, I briefly deal with the making of my short fiction film Thursday.

Films in the closet : exploring the problematics of LGBTQ representation
Carolina Silveira, 2022, master's thesis

Abstract: Prvi del magistrskega dela raziskuje zgodovino reprezentacij LGBTQ skupnosti v filmu in medijih, s ciljem postavitve avtoričinega praktičnega projekta v kontekst, da bi ugotovili, na katere načine se le-ta vključuje v stereotipe in v katerih primerih se nahaja zunaj njih. Osredotočeno večinoma na ameriški in delno tudi na evropski film, pričujoče magistrsko delo ne predstavlja izčrpne študije teme, temveč gre za subjektivno izbiro določenih vrhuncev, ki so označili LGBTQ reprezentacijo v zgodovini filma ter pomembnih tem v odnosu do praktičnega projekta. Magistrsko delo izpostavi filme skozi desetletja in dogodke gejevskega gibanja z namenom kontekstualiziranja reprezentacije skupnosti v njenem družbeno-političnem presečišču. V svojem drugem delu avtorica razloži ustvarjalni proces filma (s)election, ki predstavlja praktični del magistrske naloge. Na koncu se oba dela povežeta.

Politični film : diplomsko delo
Benjamin Friškovec, 2022, undergraduate thesis

Abstract: Diplomsko delo obravnava nekaj ključnih vprašanja političnega filma, katerega prav tako definira ter kontekstualizira. Na začetku se posvetimo tipologiji političnega, ki presega zgolj obravnavanje vladajočega razreda, politikov kot oseb in izvajanje oblasti. Razločevanje med zgoraj opisanim in sfero skupnih zadev, ki se dotikajo naših življenj na vseh nivojih povežemo s filmom in za boljše razumevanje razširimo s temami, kot so žanr, teorija avtorstva, metode potujitve in realizem. Vsi ti dejavniki namreč vplivajo na definicijo političnega filma. Ključen faktor političnega filma je lahko prav produkcija filma, in sicer z rušenjem tradicionalnih hierarhij v procesu zasnove in produkcije filma. Prav politika je tisto, kar neposredno vpliva na naša življenja. Če film prikazuje perspektivo upornikov in ljudi, ki sicer ne bi imeli besede, če daje gledalcu možnost kritičnega razmišljanja o subjektu, temi ali sistemu in če je realističen, govorimo o političnem filmu. Za lažje razumevanje politične filme različnih klasifikacij razporedimo v kategorije in v nadaljevanju tudi razložimo, kako se tema povezuje s praktičnim delom diplomske naloge, ki ga predstavlja diplomski film z naslovom Ni vsak dan nedelja.

Thermal diffusivity downscaling of molybdenum oxide thin film through annealing temperature-induced nano-lamelle formation: a photothermal beam deflection study
S. Soumya, Vimal Raj, Mohanachandran Nair Sindhu Swapna, Sankaranarayana Iyer Sankararaman, 2021, original scientific article

Abstract: The present work proposes a method of downscaling the thermal diffusivity (α) of MoO3 thin films through annealing temperature-induced nano-lamelle formation. The thermal diffusivity modification of the MoO3 films, prepared by the doctor blade method, is investigated by the sensitive transverse photothermal beam deflection technique. The X-ray diffraction analysis confirms the structural phase transformation from monoclinic to orthorhombic in the films annealed from 300 to 450 °C. The thermal induced anisotropy of the film is evident from the variation of the morphology index and texture coefficient. The field emission scanning electron microscopic analysis unveils the morphology modifications from blocks to the nano-lamelle structure with layers of average thickness ~ 77 nm. The thermal diffusivity measurement reveals a 53% reduction upon annealing the film to 450 °C. The drastic reduction is achieved through the annealing temperature-induced nano-lamelle formation and the phase transformation from monoclinic to orthorhombic in the MoO3 films.

Red modernism : the films of Miklos Jansco
2022, radio or television broadcast, podcast, interview, press conference

Abstract: One of the most acclaimed Eastern European directors of the late 1960s, Miklos Jancsó became known for his abstract long-take style which explored the intersections of power, politics, history, and myth. (“Radical form in the service of radical content,” as the Village Voice film critic, James Hoberman, put it back then.) Now that the Beacon Cinema in Columbia City is hosting a retrospective of six of his films (including Red Psalm, which won him the best director prize at the 1972 Cannes Film Festival), Red May has invited three film scholars--Eszter Polonyi, Zoran Samardzija, and Steven Shaviro—to discuss Jancsó’s boldly stylized film language with Tommy Swenson, Film Curator of the Beacon Cinema
