Condensations and Extensions
Aleš Vaupotič, Narvika Bovcon, 2017, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: Every reading of a text follows a complex mechanism, which is outlined in phenomenological terms in Roman Ingarden's Das literarische Kunstwerk (1930) and later in reader-response criticism. Also Roland Barthes's explorations of intertextuality point in a similar direction of the text as heterogeneous and open texture. The complex mechanisms that allow the reader to gain meanings and construct represented objects etc. are scrutinized to emphasize the importance of the reader's collaboration in the readerly act and the transformations to the textual experience that depend on historical circumstances, on cultural and personal experience of the reader. Considering these critical traditions, any text is always interactive, an ad hoc construct, it comes to life only in contact with alien contexts whereby it virtually looses its supposed lasting identity. In Theorising the Digital Scholarly Edition (Literature Compass 7.2, 2010) Hans Walter Gabler attempts to provide a conceptual framework for a critical scholarly edition, a text genre which is supposed to preserve the original documents and the texts and/or works. However, Gabler rejects the ideology of preservation of memory in the »pure« form and argues for a relational and contextual idea of edition as a »knowledge site«. In addition, he states that the digital medium and the print medium can coexist since they serve different purposes, the printed edition is used for reading and the digital one for »use« and study purposes. The so-called old scholarly editions (pre-positivist) had a strong emphasis on the commentary, which added to the authorial function of the editor as the mediator between the vast textual archive and the receptive abilities of the addressee. Text-edition as a dynamic and collaborative »knowledge site« is sometimes introduced by the characteristics of a particular text. Dora García's art project and video installation The Joycean Society (2013) documents with a video (53 min.) and by exhibiting artefacts the reading process of the mysterious Finnegan's Wake (1939) by James Joyce, the multiple readings within a single heterogeneous reading group of the same book for 30 years. The second case study is the artist's book by a Slovenian net.artist Teo Spiller Znakovnost novih medijev (Semiotics of New Media, 2011). The printed illustrated pages are intended to be read in parallel with browsing the online versions of the art projects presented. Another key dimension of such book-projects is the swift change and disappearance of the on-line part of this plural reading-interface. The third example considered are the projects by Jaka Želaznikar, a Slovene digital poet, that relate to the works of one of the main Slovenian poets Tomaž Šalamun (1941-2014). Among them Železnikar's on-line project Izbris Šalamun (Deletion Šalamun, 2015), which is an on-line edition of two poetry books by Šalamun, Letni čas (Season, 2010) and Ta, ki dviga tačko, spi (The one, who rises the paw, sleeps, 2015), enables the reader to selectively delete the words from poems. The text will examine the reader's reception of the poems in the printed version and in the on-line interface. In this case, too, the context of the edition will be considered (the link with the publishing house and the printed edition, the role in promotion activities of the on-line edition in respect to the printed one).

Prostor, vržen iz tira
Srečo Dragan, Aleš Vaupotič, Narvika Bovcon, 2017, intervju

Opis: Prostor, vržen iz tira, razstava Sreča Dragana, likovnega umetnika, videasta, konceptualista in novomedijskega umetnika, tudi energičnega univerzitetnega profesorja, mentorja ter producenta in organizatorja odmevnih dogodkov in sodelovanj, pokriva pet desetletij umetniškega delovanja in ustvarjanja. V zasnove in izvedbe včasih tehnično izjemno zahtevnih projektov so bili vpleteni mnogi sodelavci in ustvarjalci. Do leta 1987 je Srečo Dragan umetniško deloval v tandemu z Nušo Dragan. Razstava se v naslovu navezuje na Draganovo retrospektivo v Moderni galeriji v Ljubljani leta 2000 z naslovom Čas, vržen iz tira: 1968–2000, ki privzema del Hamletovega verza: »The time is out of joint.« Takrat je razstavo pospremil programski zapis: »Inštitucija tehno-modificiranega pogleda kot primarnega okolja Draganovega medijskega ustvarjanja je od vseh, ki smo to predstavitev pripravljali, zahtevala spremembo klasične pregledne razstave v obliko kot-darazstave. To je bil osnovni model-ideja, ki omogoča polje za testne in problematične transferje za nove tehnologije, tehno-znanosti in elektronske, še posebej pa kibernetične umetnosti. / Trije interaktivni razstavni prostori-teritoriji, ki jih zasedajo nematerialne strukture kot-da-umetniška dela, predstavljajo aktivne točke komunikacije« (black.fri. uni-lj.si/sdmg2001). Tako kot na prelomu tisočletja se tudi letošnja retrospektiva vzpostavlja iz avtorskega urejevalnega in reaktualizirajočega postopka. Dela niso preprosto dana na ogled, ampak na novo aktivirana prek preteklih in sodobnih kontekstov. Naslov namiguje, da se nekaj zanimivega tokrat dogaja s prostorom. Pomembno vlogo igra pet stopenj rekonceptualizacije projektov, označene so bile z napisi na tleh galerije: konceptna tabla 1.0 vsebuje izvirni koncept, rekonceptualizacija 2.0 je instalacija-dokument dela kot novo avtorsko delo, tabla 3.0 rekonceptualizira kot modul za razstavljanje zgodovinsko kontekstualiziranih projektov na skupinskih razstavah, 4.0 konceptualizira robotsko vodenje obiskovalca po razstavi in končna faza 5.0 – to je živa podatkovna baza komentarjev obiskovalcev Draganovih razstav ter udeležencev v njegovih projektih.

Design of a highly photocatalytically active ZnO/CuWO4 nanocomposite
Matjaz Valant, Saim Emin, 2017, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje)

Opis: We report the synthesis, photocatalytic activity and mechanistic study of a novel heterostructure (HTS) with an efficient charge separation. A ZnO/CuWO4 HTS material is reported for the first time. The nanocomposite (NC) consists of CuWO4 nanoparticles (ca. 200-400 nm) decorated with ZnO nanorods (ca. 30 nm, 100 nm length) and is shown to be a highly active photocatalyst for decomposition of model contaminants including methyl orange and terephthalic acid. The ZnO/CuWO4 interface is shown to be the key for controlling the enhanced activity of the composite material. Transient absorption spectroscopy studies demonstrated that a photoinduced charge transfer across the ZnO/CuWO4 interface increased electron-hole lifetime by 3 orders of magnitude, from < 20 s in ZnO to 30 ms in the ZnO/CuWO4 NC sample. Our findings show that through interface design efficient HTS materials can be prepared for a wide range of photocatalytic applications.

Atomic-level mechanisms of magnesium oxidation
Dmytro Orlov, Matjaž Valant, Sandra Gardonio, Mattia Fanetti, 2016, objavljeni znanstveni prispevek na konferenci

Opis: Magnesium has been recently becoming an increasingly popular material for various applications. However, excessive chemical reactivity, and oxidation rate in particular, is a major obstruction on the way of Mg to become widely adopted. A significant problem causing the lack of Mg reactivity control is insufficient understanding of mechanisms involved in the oxidation of magnesium surface. Herewith we present the investigation of atomic-level mechanisms of oxidation initiation and propagation in pure Mg. Namely, X-ray photoelectron spectroscopy at synchrotron Elettra was used as a surface sensitive direct method to determine the valence of Mg and O and the valence band states at the early stage of oxide formation over a principal, most densely packed, crystallographic plane (0001) in pure Mg. The mechanisms of oxygen adsorption on magnesium free surface followed by oxidation (i.e. initiation and kinetics of MgO formation) are clarified.
