Farewell from Friedhart Klix
(2005)
Metal nanoparticles are the most frequently used nanostructures in plasmonics. However, besides nanoparticles, metal nanowires feature several advantages for applications. Their elongation offers a larger interaction volume, their resonances can reach higher quality factors, and their mode structure provides better coupling into integrated hybrid dielectric-plasmonic circuits. It is crucial though, to control the distance of the wire to a supporting substrate, to another metal layer or to active materials with sub-nanometer precision. A dielectric coating can be utilized for distance control, but it must not degrade the plasmonic properties. In this paper, we introduce a controlled synthesis and coating approach for silver nanowires to fulfill these demands. We synthesize and characterize silver nanowires of around 70 nm in diameter. These nanowires are coated with nm-sized silica shells using a modified Stober method to achieve a homogeneous and smooth surface quality. We use transmission electron microscopy, dark-field microscopy and electron-energy loss spectroscopy to study morphology and plasmonic resonances of individual nanowires and quantify the influence of the silica coating. Thorough numerical simulations support the experimental findings showing that the coating does not deteriorate the plasmonic properties and thus introduce silver nanowires as usable building blocks for integrated hybrid plasmonic systems.
Die Manosphere
(2020)
Die sogenannte Manosphere – eine digitale Gemeinschaft, die sich hauptsächlich durch misogyne und antifeministische Beiträge und Ideologien auszeichnet – ist aufgrund ihrer Verbindung zu verschiedenen Terroranschlägen in der letzten Zeit verstärkt in das Blickfeld der Medien gelangt. Dieser Beitrag untersucht die bislang häufig vernachlässigte Rolle digitaler Räume und Netzwerke im Kontext regressiver, frauenfeindlicher Ideologien und daraus erwachsende gewalttätige antifeministische Handlungsrepertoires aus Perspektive der Bewegungsforschung. Am Beispiel der Manosphere auf der Plattform Reddit zeige ich, wie durch das Zusammenspiel zwischen technologischer Infrastruktur und regressiver Ideologie die Grundlage für die Mobilisierung und Sozialisierung in antifeministische Bewegungskulturen mit gewalttätigen Handlungsrepertoires on- und offline geschaffen wird.
The United Nations (UN) policy agenda on Preventing and Countering Violent Extremism (P/CVE) promotes a “holistic” approach to counterterrorism, which includes elements traditionally found in security and development programs. Advocates of the agenda increasingly emphasize the importance of gender mainstreaming for counterterrorism goals. In this article, I scrutinize the merging of the goals of gender equality, security, and development into a global agenda for counterterrorism. A critical feminist discourse-analytical reading of gender representations in P/CVE shows how problematic imageries of women as victims, economic entrepreneurs, and peacemakers from both the UN’s Sustainable Development Goals and the Women, Peace and Security agenda are reproduced in core UN documents advocating for a “holistic” P/CVE approach. By highlighting the tensions that are produced by efforts to merge the different gender discourses across the UN’s security and development institutions, the article underlines the relevance of considering the particular position of P/CVE at the security–development nexus for further gender-sensitive analysis and policies of counterterrorism.
The Other Side
(2020)
Given the current polarization of gender knowledge in the public discourse, this article investigates the "other side" of gender knowledge production. Building on feminist standpoint literature, I conduct a close reading of the affective-discursive dynamics of knowledge production in two anti-feminist online communities in the United States and India. I find that anti-feminist communities appropriate feminist practices of consciousness-raising to construct a shared sense of victimization. This appropriation is, however, incomplete. In contrast to feminist practices, anti-feminist knowledge generation is premised on the polarizing themes of "ultimate victimhood" and "ultimate other," which lead to violence and exclusion, rather than liberation.
Women's rights are a core part of a global consensus on human rights. However, we are currently experiencing an increasing popularity of anti-feminist and misogynist politics threatening to override feminist gains. In order to help explain this current revival and appeal, in this article I analyse how anti-feminist communities construct their collective identities at the intersection of local and global trends and affiliations. Through an in-depth analysis of representations in the collective identities of six popular online anti-feminist communities based in India, Russia and the United States, I shed light on how anti-feminists discursively construct their anti-feminist 'self' and the feminist 'other' between narratives of localized resistance to change and backlash against the results of broader societal developments associated with globalization. The results expose a complex set of global-local dynamics, which provide a nuanced understanding of the differences and commonalities of anti-feminist collective identity-building and mobilization processes across contexts. By explicitly focusing on the role of discursively produced locations for anti-feminist identity-building and providing new evidence on anti-feminist communities across three different continents, the article contributes to current discussions on transnational anti-feminist mobilizations in both social movement studies and feminist International Relations.
