RESUMO
Exotic features of two-dimensional materials have been demonstrated, making them particularly appealing for both photocatalytic and photovoltaic applications. van der Waals corrected density functional theory calculations were performed on AAII-Se MoSSe, AAII-Te MoSTe, and AAII-Se WSSe heterostructures in this study. Our findings reveal that the heterostructures have high stability due to the tiny lattice mismatch and binding energy, which is extremely favorable for epitaxial growth of these heterostructures. According to the electronic band gap calculation, AAII-Se MoSSe and AAII-Se WSSe are semiconducting materials, while AAII-Te MoSTe has metallic properties. Interestingly, all three heterostructures have type II band gap alignment, which is advantageous for photovoltaic and photocatalytic applications. Furthermore, it was discovered that AAII-Se MoSSe and AAII-Se WSSe heterostructures exhibit high power conversion efficiency of up to 12.15% and 9.37%, respectively. Based on these intriguing features, the two heterostructures are excellent prospects for photovoltaic applications. The heterostructures have no appropriate band edge sites for overall water splitting at pH = 0, but they are good for the oxygen evolution process. It is feasible to alter the position of the band edges using strain resulting in improved overall water splitting by the heterostructures.
RESUMO
Although extensive efforts were made to improve maternal and child health, the magnitude of home child-birth is considerably high in Ethiopia. Therefore, this meta-analysis aimed to estimate the effect of lack of ANC visit and unwanted pregnancy on home child-birth among reproductive-age women in Ethiopia. International databases, including Cochrane Library, Google Scholar, PubMed, Global Health, HINARI, and CINAHL were searched systematically to identify studies reporting the prevalence of home child-birth and its association with lack of ANC visit and unwanted pregnancy among reproductive-age women in Ethiopia. STATA/SE version-14 was used to analyze the data and Der Simonian and Liard's method of random effect model was used to estimate the pooled effects. The heterogeneity between study and publication bias was assessed by using I-squared statistics and Egger's test respectively. A total of 19 studies with 25,228 study participants were included in this meta-analysis. The pooled prevalence of home child-birth among reproductive-age women in Ethiopia was 55.3%. Sever heterogeneity was exhibited among the included studies (I2 = 99.8, p = 0.000). The odds of home child-birth among mothers who have no ANC visit was 3.64 times higher compared to their counterparts [OR = 3.64, 95%, CI: (1.45, 9.13)]. There was significant heterogeneity among the included studies (I2 = 94%, p = 0.000). However, there was no statistical evidence of publication bias in the pooled effect of lack of ANC visit on home child-birth (P = 0.302). Women who experienced unwanted pregnancy were 3.02 times higher to give birth at home compared to women with a wanted pregnancy [OR = 3.02, 95%CI: (1.19, 7.67)]. Severe heterogeneity was exhibited (I2 = 93.1%, p = 0.000) but, there was no evidence of significant publication bias in the pooled effect of unwanted pregnancy on home child-birth (P = 0.832). The proportion of home child-birth among reproductive-age women in Ethiopia remains high. Lack of ANC visit and unwanted pregnancy had a significant effect on the practice of home child-birth. Strengthening behavioral change communication programs should be the primary focus area to improve institutional delivery service utilization among women with lack of ANC visit and unwanted pregnancy.
