Purpose The purpose of this study is to systematically review the literature on the intersections among family, migration and entrepreneurship in the context of Vietnam. This paper aims to shed light on the current state of knowledge of the research field by highlighting some key bibliographic trends among existing literature, mapping existing knowledge in the field of research and recommending future research agenda. Design/methodology/approach This study adopts a systematic literature review approach with five steps. A list of 24 papers that are extracted from a pool of 643 papers in the Core Collection of Web of Science and Scopus were selected as the most relevant to the research questions used for further in-depth analysis. Findings Bibliometric analysis indicates that this research field is considered an infant research stream that is dominated by qualitative empirical studies. Content analysis reveals how Vietnamese migrant families mobilize and use various kinds of cultural, social, human and financial capital for entrepreneurship. They also generate resources to develop family-owned enterprises that are expected to be continued over generations. Five research gaps for future research are identified: functions of family, downsides of networks, the role of transnational and returnee entrepreneurs, gender and methodology. Research limitations/implications The choice of a limited number of keywords and access to only two databases (Web of Science and Scopus) are limitations of this study. Furthermore, the selection of the articles for content analysis is subjective although research triangulation is applied in this review. Originality/value This research is a pioneering systematic literature review that sheds light on the interconnectedness of family, migration and entrepreneurship in the case of Vietnamese migrant entrepreneurs.

This study focuses on the influence of gold nanoparticle sizes on optical and electrical properties of Au@TiO2 nanocomposite films. Here, the gold nanoparticles (AuNPs) of different sizes of 5 nm, 10 nm, 20 nm, 40 nm and 60 nm were dispersed onto nanoporous TiO2 thin films to form Au@TiO2 nanocomposite films. FE-SEM images and UV-vis absorption spectra show that AuNPs had good dispersion on the TiO2 films and all Au@TiO2 nanocomposite films exhibited a good surface plasmon resonance (SPR) with the resonance absorption peaks in the visible light region (about 550 nm). The effect of AuNPs on the films photoluminescence property was investigated using excited laser light of 325 nm wavelength at room temperature. The films electrical properties were studied from the change of the photocurrent under illumination of solar simulator and UV light source. The results show that the presence of gold nanoparticles has significantly improved the photocurrent of Au@TiO2 nanocomposite films and especially when AuNPs size was less than 20 nm. In addition, we also found that the photocurrent magnitude of the films with small AuNPs sizes (5 nm and 10 nm) under solar simulator light was 4 times larger than the one under UV light. These results indicate that AuNPs size had a great influence on the improvement of photocurrent in nanocomposite films.
