| 1 | Single titanium-oxide species implanted in 2D g-CsN4 matrix as a highly efficient visible-light CO2 reduction photocatalyst显示文摘A visible-light-response, efficie nt and robust photo-catalyst for CO2 reduction is highly desirable. Herein, we demonstrate that single titanium-oxide species impla nted in two-dime nsion al (2D) graphitic carb on n itride (g-C3N4) matrix (2D TiO-CN) can efficie ntly photo-catalyze the reduction of CO2 to CO under the irradiation of visible light. The synergistic interaction between single titanium oxide species and g-C3N4 in 2D TiO-CN not only enhances the separation of photo-excited charges, but also results in visible light response of single titanium-oxide species, realizing high activity of CO2 photo-reduction with extremely high CO generation rate of 283.9 pmol·h^-1·g^-1, 5.7, 6.8 and 292.2 times larger than those of TQ2/CN hybrid material, CN and commercial TiO2, respectively. Time-resolved fluoresce nee and electron spin resonance spectroscopy revealed the catalytic mechanism of the fabricated 2D TiO-CN photocatalysts for CO2 reduction. | Shangfeng Tang Xuepeng Yin Guanyu Wang Xiuli Lu Tongbu Lu | 2019 | Nano Research2019，12，2： | 8 |
| 3 | Preventive behaviours and family inequalities during the COVID-19 pandemic:a cross-sectional study in China显示文摘Background The coronavirus disease 2019(COVID-19)pandemic is an international public health threat,and people's participation in disease-related preventive behaviours is the key to controlling infectious diseases.This study aimed to assess the differences in adopting preventive behaviours among populations to explore potential individual and household factors and inequalities within families.Methods This online survey was conducted in April 2020.The directional stratified convenient sampling method was used to select 4704 participants from eight provinces in eastern,central,and western China.The questionnaire included demographic information,household variables,and five target prevention behaviours.The chi-squared test,binary multilevel model,and Mantel–Haenszel hierarchical analysis were used for data analysis in the study.Results Approximately 71.2%of the participants had appropriate outdoor prevention,and 32.9%of the participants had indoor protection in place.Sharing behaviours(P<0.001)and education level(P<0.001)were positively associated with adopting preventive measures.The inhibiting effect of household crowding and stimulating effect of high household income on preventive behaviours were determined in this study.Household size was negatively associated with living area(β=-0.057,P<0.05)and living style(β=-0.077,P<0.05).Household income was positively associated with age(β=0.023,P<0.05),and relationship with friends(β=0.053,P<0.05).Vulnerable groups,such as older adults or women,are more likely to have inadequate preventive behaviours.Older adults(OR=1.53,95%CI 1.09–2.15),women(OR=1.37,95%CI 1.15–1.64),and those with more than 2 suspected symptoms(OR=1.85,95%CI 1.07–3.19)were more likely to be affected by the inhibiting effect of household crowding,while the stimulating effect of high household income was limited in these groups.Conclusions Inequalities in COVID-19 prevention behaviours exist between families and inadequate adoption of prevention by vulnerable groups are noteworthy.This study expands the research perspective by emphasizing the role of household factors in preventive behaviours and by focusing on family inequalities.The government should use traditional media as a platform to enhance residents’public health knowledge.Targeted additional wage subsidies,investments in affordable housing,financial support for multigenerational households,and temporary relocation policies may deserve more attention.Communities could play a critical role in COVID-19 prevention. | Yisheng Ye Ruijun Wu Yao Ge Tao Wang Xin Yao Yao Yang Chengxu Long Fangfei Chen Shangfeng Tang Rui Huang | 2021 | Infectious Diseases of Poverty2021，10，4： | 0 |
