The origin of the political. Hannah Arendt or Simone Weil
No full textIn this book Roberto Esposito explores the conceptual trajectories of two of the twentieth century's most vital thinkers of the political: Hannah Arendt and Simone Weil. Taking Homer's Iliad-that "great prism through which every gesture has the possibility of becoming public, precisely by being observed by others"- as the common origin and point of departure for our understanding of Western philosophical and political traditions, Esposito examines the foundational relation between war and the political. Drawing actively and extensively on Arendt's and Weil's voluminous writings, but also sparring with thinkers from Marx to Heidegger, The Origin of the Political traverses the relation between polemos and polis, between Greece, Rome, God, force, technicity, evil, and the extension of the Christian imperial tradition, while at the same time delineating the conceptual and hermeneutic ground for the development of Esposito's notion and practice of "the impolitical." In Esposito's account Arendt and Weil emerge "in the inverse of the other's thought, in the shadow of the other's light," to "think what the thought of the other excludes not as something that is foreign, but rather as something that appears unthinkable and, for that very reason, remains to be thought." Moving slowly toward their conceptualizations of love and heroism, Esposito unravels the West's illusory metaphysical dream of peace, obliging us to reevaluate ceaselessly what it means to be responsible in the wake of past and contemporary forms of war
Enhanced photocatalytic hydrogen evolution via ball-milled PtO<sub>2</sub>/TiO<sub>2</sub> heterojunction photocatalyst: an alternative approach for efficient energy production
No full textA novel PtO2/TiO2 heterojunction photocatalyst was synthesized via ball milling and investigated for its potential in photocatalytic hydrogen production. The effects of PtO2 loading, catalyst concentration, and sacrificial agent concentration on the hydrogen evolution rate (HER) were systematically evaluated. The results indicate that increasing the PtO2 concentration in the catalyst significantly enhances the hydrogen production rate, reaching a maximum value of approximately 54 mmol∙h−1∙g−1 at a PtO2 concentration of 20 wt%. The effect of the sacrificial agent concentration on the hydrogen production exhibited a Langmuir-Hinshelwood behavior with constant hydrogen production rates at sacrificial agent concentrations greater than 2.5 M. The experimental results were described by a kinetic model to shed light on the reforming mechanism. Finally, the stability of the photocatalyst was confirmed through four consecutive cycle tests. This synergistic integration of experimental and modelling analyses provides a robust platform for uncovering mechanistic details of photocatalytic hydrogen generation using a photocatalyst synthesized through a facile preparation method.</p
