ABSTRACT
Despite high hepatitis B (HBV) prevalence among people of Vietnamese ethnicity in Australia and elsewhere, there is limited research on levels of HBV knowledge and factors associated with such knowledge. The aim of this study was to examine HBV knowledge and associated demographic and attitudinal factors among people of Vietnamese ethnicity in Australia. People of Vietnamese ethnicity (n = 966) were recruited through community events and social media groups to complete online surveys measuring HBV knowledge, attitudes towards HBV, levels of mistrust in Western medicine, and demographic characteristics. Findings of this study indicate that levels of knowledge are mixed, with gaps in knowledge related to transmission and treatment of the virus. Those with greater knowledge of HBV tended to be older, have higher levels of formal education, have been tested for HBV, and know someone living with HBV. Those with lower levels of knowledge tended to have more negative attitudes towards the virus and greater levels of mistrust in Western medicine. Given that health literacy is connected to effective communication from health providers, we suggest that there is a need for the development of health promotion and education resources targeted at people of Vietnamese ethnicity and translated into Vietnamese. We propose that such resources be developed in consultation with Vietnamese communities and health providers to ensure that they are culturally appropriate and sensitive to people of Vietnamese ethnicity living in Australia.
ABSTRACT
The sustainable production of hydrogen peroxide (H2O2) from oxygen and water has become an exciting research hotspot in the scientific community due to the importance of this fine chemical in various fields. Besides, piezo-photocatalysis is an emerging star for generating H2O2 from these green reagents. For developing catalysts for this specific application, doping heteroatoms into carbon-based materials such as graphitic carbon nitrides (g-C3N4) is a growing fascination among worldwide scientists. However, systematic study on the effects of doping precursors on the catalytic results is still rare. Herein, we fabricated sulfur (S) and selenium (Se) doped g-C3N4 with various doping precursors to evaluate the effects of these agents on the production of H2O2 under light and ultrasound irradiation. Based on the results, Se-doped g-C3N4 gave an outstanding catalytic performance compared to S-doped g-C3N4, even in a significantly low quantity of Se. In order to fully understand the chemical, physical, optical, and electronic properties of pristine g-C3N4 and its derivatives, the as-prepared materials were thoroughly analyzed with various tools. Thus, this study would give more profound insights into doping techniques for carbon-based materials and encourage further research on the design and development of piezo-photocatalysts for practical applications.
