This study aims to explore the synergistic effect of oxide nanoparticles (ZnO, Fe₂O₃, SiO₂) and cerium nitrate inhibitor on anti-corrosion performance of epoxy coating. First, cerium nitrate inhibitors are absorbed on the surface of various oxide nanoparticles. Thereafter, epoxy nanocomposite coatings have been fabricated on carbon steel substrate using these oxide@Ce nanoparticles as both nano-fillers and nano-inhibitors.

To evaluate the impact of oxides@Ce nanoparticles on mechanical properties of epoxy coating, the abrasion resistance and impact resistance of epoxy coatings have been examined. To study the impact of oxides@Ce nanoparticles on anti-corrosion performance of epoxy coating for steel, the electrochemical impedance spectroscopy has been carried out in 3% NaCl solution.

ZnO@Ce3+ and SiO2@Ce3+ nanoparticles provide more enhancement in the epoxy pore network than modification of the epoxy/steel interface. Whereas, Fe2O3@Ce3+ nanoparticles have more to do with modification of the epoxy/steel interface than to change the epoxy pore network.

Incorporation of both oxide nanoparticles and inorganic inhibitor into the epoxy resin is a promising approach for enhancing the anti-corrosion performance of carbon steel.

Drawing on ethnographic field research on female sex workers and male clients in Ho Chi Minh City, Vietnam’s global sex industry, this paper complicates our understanding of human trafficking in two ways. First, introducing the term perverse humanitarianism, the paper extends work on carceral feminism by offering concrete examples of interagency commitments between NGOs and the police. Second, my ethnography reveals that women framed their relationships with male clients as mutually beneficial because the men provided them with alternate pathways to economic mobility outside of sex work. Drawing on the same tropes of victimhood employed by the NGOs, sex workers elicited sympathy from male clients that they leveraged into gifts of money. Using men’s charitable gifts, many women became small entrepreneurs who opened local businesses and empowered other sex workers far beyond what NGOs were able to provide.

Drawing from emotional labour (EL) and emotion regulation (ER) theories, this paper aims to identifiy what helps and what hinders the emotional intelligence (EI) practice of Vietnamese hotel workers. Researching EI qualitatively from a novel context highlights the influence of culture on EI.

The critical incident technique (CIT) was adopted as the qualitative methodological approach using a self-administered form and semi-structured interviews to collect empirical data from a sample of 34 Vietnamese hotel workers in 19 different hotels.

The findings show that following Joseph and Newman’s (2010) cascading model of EI would help hotel workers in their practice. The research also found different factors hindering the EI practice from the individual and organisational levels. Vietnamese culture was believed to guide deep-acting and meditation. Language barrier and manager support emerged as significant factors that could help or hinder their EI practice.

The research proposes a conceptual framework addressing the factors that could help or hinder the EI practice and provides implications for HR practices and management. Caution could be taken when applying the research implications because of the small sample as a nature of qualitative research.

To the best of the authors’ knowledge, this is the first attempt to appraise the EI practice adopting the CIT as a qualitative methodological approach in an under-research context and add evidence to the theoretical links between EI, EL and ER.
