Eastern exoticism: Thackeray as tourist and anti-tourist
(Istanbul Universitesi, Edebiyat Fakultesi - University of Istanbul, Faculty of Letters, 2021) Kennedy, Valerie
William Makepeace Thackeray’s 1846 Notes on a Journey from Cornhill to Grand Cairo exemplifies the complexity of nineteenth-century travel-writing where exploration exists alongside tourism (and anti-tourism). In key Ottoman locations like Smyrna, Constantinople, and Cairo, the narrator’s desire for Oriental exoticism is sometimes realised but often disappointed as the East becomes increasingly modernised and Westernised. These conflicting perspectives are expressed through allusions, East-West comparisons, and irony and satire in a self-conscious and unstable narrative. William Makepeace Thackeray’in 1846 tarihli Notes on a Journey from Cornhill to Grand Cairo keşfin turizmle (ve turizm karşıtlığıyla) birlikte yer aldığı on dokuzuncu yüzyıl seyahat yazılarının karmaşıklığına örnek teşkil eder. İzmir, İstanbul, Kahire gibi Osmanlı şehirlerinde yazarın Doğu egzotizmi hevesi, Doğu’nun giderek modernleşmesi ve Batılılaşmasıyla ancak bazen gerçekleşmekte, fakat çoğu zaman hayal kırıklığıyla sonuçlanmaktadır. Bu çelişkili bakış açıları imalarla, Doğu-Batı karşılaştırmalarıyla, mahcup ve güvenilmez bir anlatı dâhilinde ironi ve taşlamayla aktarılır.

Efficient synthesis of plate-like crystalline hydrated tungsten trioxide thin films with highly improved electrochromic performance
(Royal Society of Chemistry, 2011) Jiao, Z.; Wang, X.; Wang, J.; Ke, L.; Demir, Hilmi Volkan; Koh, T. W.; Sun, X. W.
Plate-like hydrated tungsten trioxide (3WO(3)center dot H(2)O) films were grown on a fluorine doped tin oxide (FTO) coated transparent conductive substrate via an efficient, facile and template-free hydrothermal method. The film exhibited a fast coloration/bleaching response (t(c90%) = 4.3 s and t(b90%) = 1.4 s) and a high coloration efficiency (112.7 cm(2) C(-1)), which were probably due to a large surface area.

Karabük Postası: Karabük'ün uzun soluklu yerel gazetesi
(Bilkent University, 2024) Zegerek, Ahmet Fatih; Acar, Eren; Kafadar, Sahra Nur; Pekşen, Selim; Tümbaş, Zehra
Karabük Postası 1956 yılında kurulmuş ve günümüzde hala daha Karabük’te varlığını devam ettiren yerel bir gazetedir. HIST 200 dersi kapsamında proje olarak Karabük Postası’nın Türkiye’deki yerel gazeteler arasındaki konumu, onlardan ayrışan ve benzerliklere inceledik. Karabük Postası’nda 1960-2000 yılları arasında ne tarz haberlerin (ekonomi, askeri, gündem, sağlık ve cinsellik, yerel ve dünya magazini, çevre ve spor, sanat) basıldığını ve yer verildiğini inceledik. Bu haberlerden ve 35 yıldır Karabük Postası’nın çalışanı olan Nurettin Acar ile yaptığımız röportajdan yola çıkarak Karabük Postası’nın 1960 yılından günümüze kadar ne gibi değişim ve gelişmelere tanıklık ettiğini gözlemleyip makalemizde yer verdik.

Morphology-tailored synthesis of tungsten trioxide (Hydrate) thin films and their photocatalytic properties
(ACS Publications, 2011-01-10) Jiao, Z. H.; Wang, J. M.; Ke, L.; Sun, X. W.; Demir, Hilmi Volkan
Tungsten trioxide hydrate (3WO(3)center dot H(2)O) films with different morphologies were directly grown on fluorine doped tin oxide (FTO) subsi:rate via a facile crystal-seed-assisted hydrothermal method. Scanning electron microscopy (SEM) analysis showed that 3WO(3)center dot H(2)O thin films composed of platelike, wedgelike, and sheetlike nanostructures could be selectively synthesized by adding Na(2)SO(4), (NH(4))(2)SO(4), and CH(3)COONH(4) as capping agents, respectively. X-ray diffraction (XRD) studies indicated that these films were of orthorhombic structure. The as-prepared thin films after dehydration showed obvious photcicatalytic activities. The best film grown using CH(3)COONH(4) as a capping agent generated anodic photocurrents of 1.16 mA/cm(2) fork oxidization of methanol and 0.5 mA/cm(2) for water splitting with the highest photoconversion efficiency of about 0.3% under simulated solar illumination.

Racing toward history: Utopia and progress in John Guare’s a free man of color
(University of Toronto Press, 2015) Mansbridge, J.
This article examines the way John Guare’s A Free Man of Color (2010) mobilizes a metatheatrical aesthetic to question the methods we use to organize our understandings of the past and formulate our projections of the future. Looking specifically at George C. Wolfe’s production at Lincoln Center’s Vivian Beaumont Theatre and drawing on the work of Reinhart Koselleck and Ernst Bloch, the article shows how Guare’s densely textured epic stages a metatheatrical duel between two competing forces of history: one grounded in Enlightenment notions of progress (rational, linear, forward movement), the other in utopia (an imagined future always on the horizon). As progress and utopia jostle for the authority to define the history – and so also the future – that the play re-enacts, it becomes clear to the audience that what is at stake, in our present, is the meanings and practices of citizenship, race, sexuality, and class that history defines.

Reaction in politics
(Brill, 2020) Alexander, James
Reaction is a subject usually avoided by political theorists, since it raises awkward historical, philosophical and political questions. Perhaps philosophers of history might make better sense of it. In this article I claim that reaction has to be understood in relation to the concepts of revolution, tradition, progress and conservatism. I argue that the specific meaning of reaction is a response to the specific action that establishes the principle that order should be established only on enlightened principles. The few theorists who have dealt with reaction have disagreed about whether it is the same as conservatism or not. I show that reaction is not an element in what I call a status quo conservatism, though it is an element in any conservatism conceived more broadly. I characterise reaction in full as the attempt to reverse the establishment of the principle that only enlightened principles shall be the basis of political order, the attempt to resist the further establishment of those enlightened principles, and also the attempt to criticise contemporary enlightened politics in terms of the unenlightened standards which existed before the revolution.

Stable distorted T phase of MSi₂N₄ (M = Ru and Os) monolayers: First-principles insights into structural, vibrational, mechanical, electronic, and optical properties
(American Physical Society, 2024-07-15) Varjovi, Mirali Jahangirzadeh; Durgun, Engin; Pacchioni, Gianfranco; Tosoni, Sergio
The recent synthesis of two-dimensional (2D) MoSi₂N₄ and WSi₂N₄ crystals has given rise to a new class of 2D materials with distinctive properties and significant potential for applications in advanced technologies. The transition metal (TM) elements can potentially be substituted with other TMs, adding the possibility of introducing new members to this emerging 2D family. In this regard, we propose three structural phases (1H, 1T, and 1T′) of MSi₂N₄ (M = Ru and Os) monolayers and examine their structural, vibrational, mechanical, electronic, and optical properties using ab initio methods. The results of cohesive energies (EC) indicate that the 1T′ structures are energetically more favorable than their 1H and 1T counterparts. The calculated phonon spectra reveal that the MSi₂N₄ nanosheets in distorted 1T′ phase are dynamically stable, while their 1H and 1T forms exhibit imaginary phonon modes, signifying vibrational instability of the systems. Ab initio molecular dynamics (AIMD) simulations also confirm that the 1T′−MSi₂N₄ structures remain thermally stable, even up to 600 K, without any notable structural deformations. The mechanical properties of 1T′ structures are assessed through the computation of in-plane stiffness (Y₂D), Poisson's ratio (ν), and ultimate tensile strain (UTS). The intrinsic geometrical anisotropy of the 1T′ nanosheets induces strong orientation-dependent elastic properties, and the calculated large values of Y₂D and high UTS indicate their rigidity and suitability for strain engineering of electronic and optical properties. The calculated electronic band structures reveal that, whereas unstable 1T−MSi₂N₄ structures exhibit ferromagnetic metal properties, the stable 1T′−RuSi₂N₄ and 1T′−OsSi₂N₄ monolayers possess a nonmagnetic semiconducting ground state with indirect band gaps of 1.40 and 1.47 eV, respectively, at the level of the HSE functional. The observed shifts from metallic characteristics in the 1T phase to semiconducting nature in the 1T′ structures can be attributed to the Peierls distortion. Additionally, in accordance with the direct electronic bandgap of the 1T′−MSi₂N₄ crystals, strong optical absorption within the visible parts of the optical spectrum is estimated. Our study not only expands the family of 2D M⁢A₂⁢Z₄ crystals, but also introduces members with distinctive 1T′ geometries that exhibit promising mechanical, electronic, and optical features for nanomechanical, optoelectronic, and green-energy applications.
