In this study, we report the preparation of Bi nanoparticles (NPs) and thin films via the solventless pyrolysis of bismuth(III) dithiolates (Bi2(S2CnH2n)3, n = 3, 4) at 160–220 °C, whose thermolysis features the absence of the precursor melting and finishes before the product (Bi metal) melting, and then we demonstrate their oxidation conversion to Bi2O3 NPs and thin films at different temperatures. The polymorphs and phase transitions of so-formed Bi2O3 are highly dependent on the oxidation temperature. Pure-phase β-Bi2O3 (tetragonal), formed by thermally oxidizing Bi NPs at 400 °C, will transform to α-Bi2O3 (monoclinic) by the traditionally known phase transition or β’-Bi2O3 by the c-oriented lattice thermal expansion as the oxidation temperature increases to 500 and 600 °C, which normally leads to an incomplete β → α transition and a mixed product of β’(β)/α phases. Compared to the β phase, the lattice-expanded variant β’-Bi2O3 is found to be stable at both high temperature (500–600 °C) and room temperature (RT) and to display a wide bandgap (∼3.0 eV), a narrow visible-light absorption range and thus relatively poor activity in RhB photodegradation. Moreover, Bi NPs are also found to be oxidized to bismuth oxycarbonate (Bi2O2CO3) at RT in the presence of H2O and CO2. This work opens a novel avenue to synthesize Bi and Bi2O3 NPs and thin films and presents new findings and insights regarding the phase regulation, polymorphism and photocatalytic performance of Bi2O3.

View paper →Selling masculinity – A qualitative analysis of gender representations in social media content about “low T”

Social Science & Medicine·2026
Testosterone has long been advertised through gendered messages that link masculinity with strength, sexual performance and vitality. In recent years, this marketing has moved onto social media, where platforms offer new ways to target audiences and shape ideas about men's health. This study examines how gender and masculinity are portrayed in social media content about testosterone testing and treatment on Instagram and TikTok. Using qualitative content analysis informed by performativity theories, we constructed four themes: (1) low testosterone as a crisis of masculinity and male sexual performance; (2) the rebranding of low testosterone from an “old man's problem” to an issue affecting younger men and their fitness; (3) self-optimisation tied to stereotypical masculine ideals; and (4) the construction of a binary opposition between being a “real man” and being feminine. These portrayals align with wider online communities, often referred to as the “manosphere”, which circulate narrow and exclusionary ideas of masculinity and regressive ideas and attitudes towards femininities. The analysed social media posts prey on men's insecurities about relationships and sexual performance and co-opt advocates' emancipatory language to sell testosterone products. Such portrayals of masculinity have medicalising implications for how men perceive themselves and their mental health, but also promote capitalistic practices like consumption of testosterone products for improving the masculine self without supporting evidence.
