Redox-Mediator Enhanced Electrochemiluminescence Under Non-Aqueous Conditions, Steven J. Blom, Fazeleh Mesgari, El M.S. Martin, Egan H. Doeven, David J. Hayne, Timothy U. Connell, Peter J. Barnard, Narges Saeedizadeh, Seyed Mohammad Jafar Jalali, Paul S. Francis

Research outputs 2022 to 2026

The introduction of small-molecule redox mediators into aqueous co-reactant electrochemiluminescence (ECL) systems has emerged as an effective strategy to increase signal intensity. Herein, we investigate the influence of a series of neutral iridium(iii) complexes (Ir(pmi)3, Ir(ppy)3, Ir(ppz)3 and Ir(ppy)2(acac)) as redox mediators for co-reactant ECL in acetonitrile. Using [Ru(bpy)3]²⁺ as a benchmark luminophore and tri-n-propylamine (TPrA) as a co-reactant, the redox mediators elicit similar effects in this solvent to those of their sulfonated [Ir(sppy)3]³⁻ and [Ir(sppz)3]³⁻ analogues under aqueous conditions. The Ir(ppz)3 complex was most effective; at a concentration of 100 µM it produced an 11-fold increase …

Relating To Difficult Weather Through Creative Practice: Responses To Marrugeku’S Cut The Sky, Helena Grehan, Jo Pollitt, O. J.E. Slater, Sam Fox

Research outputs 2022 to 2026

In this paper we argue that performance and the arts invite a deliberate sensorial connection with the body and can support a bodily turn or return, in order to help artists, scholars and communities more broadly, better attune to increasing climate instability, through collaborative, supportive and reflexive storytelling. Drawing on the three “weather” symposia, the paper focusses on the second symposium which featured a keynote presentation by Rachael Swain, co-artistic director of Marrugeku, Australia’s leading Indigenous Intercultural Dance and Performance Company. Responses to Marrugeku’s work Cut the Sky are collectively presented to illuminate what Swain argues are, “Dramaturgies of consequence” …

Brief For Jonathan H. Adler As Amicus Curiae Supporting Respondents And Affirmance, Jonathan Adler

Briefs

Global climate change presents many complex and intractable legal and policy questions. Assuming this Court has jurisdiction, the legal questions in this case are comparatively simple and straightforward. Nothing in federal law, let alone the Constitution, preempts state-law claims seeking relief from injuries allegedly caused or exacerbated by petitioners’ conduct.

At issue in this case is whether allegedly aggrieved parties, including subnational governments, may seek redress under state law from defendants otherwise subject to state court jurisdiction for harms allegedly caused or contributed to by petitioners’ conduct. In order to succeed, respondents will ultimately need to show that the damages …

Orthodox Traditionalism In The Late 16th – Early 17th Century: The Religious-Anthropological Dimension, Olena Hudzenko, Olga Dobrodum

Occasional Papers on Religion in Eastern Europe

This article explores the religious-anthropological concepts in the works of Ukrainian thinkers of the late 16th and early 17th centuries. Formed in the context of Catholic expansion and intense confessional conflict, their ideas sought to preserve the Byzantine and Old Rus’ Orthodox tradition. Thinkers of this period emphasized the importance of safeguarding ancestral faith through a return to the principles of Holy Scripture, the foundational structures of early Christian doctrine, and the spiritual legacy of Kyivan Rus. These themes were especially prominent in the theological discourse of the so-called “Ostroh traditionalists,” centered around the Ostroh and Derman religious and cultural …

On The Chekist Front: Little-Known Pages Of The Life Of Ivan Voronaev (Agent "Nepliuev"), Founder Of Soviet Pentecostalism, Oleksandr Korotaiev

Occasional Papers on Religion in Eastern Europe

The figure of Ivan Voronaev (1885-1937), founder of the Soviet Pentecostal movement, occupies a contested place in the history of Eastern European Protestantism. Confessional narratives portray him as an “apostle of the Slavs” and martyr of faith, while Soviet anti-sectarian literature depicted him as a “bourgeois agent” and conduit of foreign influence. Despite their opposition, both approaches largely ignore the Chekist dimension of Voronaev’s biography–his systematic interaction with the Soviet security services and his role in their operational activities as a covert agent.

This article reconstructs previously marginalized episodes of Voronaev’s life on the basis of operational, investigative, and reporting …

Disenchantment Of The World In The Context Of The Russian-Ukrainian War,, Olga Dobrodum, Eduard Martyniuk, Olena Nykytchenko, Mykola Palinchak, Ruslana Tkachenko

Occasional Papers on Religion in Eastern Europe

The article analyzes Max Weber's concept of the "disenchantment of the world" («Entzauberung der Welt») in the context of the full-scale Russian-Ukrainian war, which began with Russia's invasion in February 2022 and continues to the present. The author examines disenchantment as a process of rationalization and desacralization of society, tracing its development from ancient origins (Epicurus) and monotheistic traditions to contemporary interpretations (Adorno and Horkheimer, Barthes, Baudrillard, Habermas, Taylor, Haraway, Latour). The paradoxical nature of the process is emphasized: secularization does not eliminate the sacred but transforms it into new forms—from commodity fetishism to digital eschatology and posthumanist animism.

These materials record humanitarian and pastoral activity while also showing how the Church publicly interpreted its response. The early response relied heavily on structures already present in dioceses and local communities, which could be redirected quickly toward …

Religious Situation In Ukraine: Main Trends And Prognostic Visions, Olena Predko, Denys Predko, Ihor Maksymenko

Occasional Papers on Religion in Eastern Europe

The contemporary religious situation in Ukraine is characterized by the resilience of religious institutions despite the full-scale war and destruction of infrastructure, which demonstrates a high level of nominal religiosity and the social significance of religion. At the same time, a profound structural transformation of the Orthodox field is underway, reflecting processes of national identification, security, and the delegitimization of pro-Russian structures. In parallel, there is a shift in religiosity from a mobilizational to a reflective, individualized form, in which faith performs psychological, meaning-making, and symbolic functions rather than mere institutional affiliation. At the same time, the post-war period retains …
