Improved empirical force field for multicomponent oxide glasses and crystals
No full textIn this paper, the self-consistent PMMCS force fields (FFs) [Pedone et al., J. Phys. Chem. B 110, 11780 (2006)10.1021/jp0611018] widely used for the simulation of a large variety of silicates, aluminosilicate and phosphate crystals, and multicomponent oxide glasses have been revised and improved by the inclusion of two types of three-body interactions acting between T-O-T bridges (T=Si and P) and network former-network former repulsive interactions. The FFs named Bertani-Menziani-Pedone (BMP)-harm and BMP-shrm better reproduce the T-O-T bond angle distributions (BADs) and network former-oxygen distances. Consequently, the prediction of Qn distributions (Q stands for quaternary species, and n is the number of bridging oxygens around it), neutron total distribution functions, solid-state nuclear magnetic resonance spectra of spin active nuclei (Si29, O17, P31, Al27), and the density have also been hugely improved with respect to the previous version of our FF. These results also highlight the strong correlation between the T-O-T BADs and the other short and intermediate structural properties in oxide glasses, which have been largely neglected in the past. In addition to the improvement of the structure, the FF has been revealed to reproduce well the ionic conductivity in mixed alkali aluminosilicate glasses and the elastic properties. The systematic comparison with other interatomic potential models, including the polarizable core-shell model, carried out in this paper showed that our potential model is more balanced and effective for simulating a vast family of crystalline and amorphous oxide-based systems
Transformation through Transculturation in Chen Xi’s Comics
No full textChen Xi (1981–), aka Long Santiao, is a UK based transnational cartoonist, writer and illustrator. With the exception of Under the sky of Rome (Luoma de tiankong xia), an illustrated novel published in 2009 by Shaanxi Normal University Press, her work consists mainly of comics and graphic novels, some of them collected in a book titled Dreams and Shadows: Tales from Planet Xi’s Teahouse, published in 2015 by the British independent publisher Line of Intent, and others self-published or simply uploaded on her blogs. Since her style – playfully called ‘Sinophone pop’ (Pedone 2018)– draws upon different cultural traditions to shape original, fluid meanings, her work can be described as transcultural (Dagnino 2012). This occurs through the massive use of scripts and images ascribable to a Chinese cultural context (traditional folklore, wuxia martial heroes, mythology and fantasy), combined with European ones (Italian writers Buzzati, Calvino, Eco, or atmospheres from Britain’s Victorian era or London’s Swinging Sixties). In a skilfully crafted paradox, Chen Xi employs commodification, fetishisation and self-Orientalisation to create a personal neonomadic, transcultural landscape. The most recurring theme in Chen Xi’s work being that of transformation, setting off from this category, the chapter aims at exploring how the aforementioned policultural aesthetic elements are transformed in Chen Xi’s work to produce a “post-loyalist” (Wang 2013) atmosphere that transcends cultural essentialisms while also distancing itself from mere displacement, or even “in- betweenness” (Bhabha 1994). Interrogating the hybridity of the graphic novel/illustrated fiction as a genre to challenge the univocity of identity, the chapter also demonstrates that Chen Xi’s work is an act of creative agency to articulate a specific Sinophone chronotope (Shih 2011), in a continued questioning of the centre/periphery matrix that reflects the author’s transformation through active (trans)culturation empowerment
