Indium oxide(In_(2)O_(3)),as a promising candidate for CO_(2)hydrogenation to C_(1) products,often suffers from sintering and activity decline,closely related to the undesirable structural evolution under reaction *** on the comprehension of the dynamic evolution,this study presents an efficient strategy to alleviate the agglomeration of In_(2)O_(3)nanoparticles by the surface decoration with highly dispersed silica species(SiO_(x)).Various structural characterizations combined with density functional theory calculations demonstrated that the sintering resulted from the over-reduction,while the enhanced stability originated from the anchoring effect of highly stable In-OSi bonds,which hinders the substantial formation of metallic In(In^(0))and the subsequent agglomeration.0.6Si/In_(2)O_(3)exhibited CO_(2)conversion rate of10.0 mmol g^(-1)h^(-1)at steady state vs.3.5 mmol g^(-1)h^(-1)on In_(2)O_(3)in CO_(2)*** steady-state activity was also achieved on Pd-modified *** to the traditional Pd/In_(2)O_(3)catalyst,the methanol production rate of Pd catalyst supported on 0.6Si/In_(2)O_(3)was enhanced by 23%,showing the potential of In_(2)O_(3)modified by SiO_(x)in serving as a platform *** work provides a promising method to design new In_(2)O_(3)-based catalysts with improved activity and stability in CO_(2)hydrogenation.

Objective: To report the clinical maternal and fetal outcomes of pregnant women with coronavirus disease 2019 (COVID-19), along with any associated pregnancy complications, in Hong Kong, China, and to assess the impact of COVID-19 vaccination on these ***: This prospective registry-based observational study included pregnant women who were recruited through convenient sampling and had a laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection with a cycle threshold (Ct) value result available on admission to eight local hospitals in Hong Kong, China. Data on clinical symptoms, laboratory results, medical treatments, delivery timing and mode, and pregnancy complications were extracted from the Hospital Authority’s electronic medical record system. Maternal, fetal, and pregnancy outcomes were compared between unvaccinated pregnant women with COVID-19 and those who had received at least one dose of COVID-19 vaccine before diagnosis. Nonparametric continuous variables and categorical variables were analyzed using the Mann-Whitneyu test and the Pearson’s chi-squared test respectively. AP value less than 0.05 was considered statistically ***: A total of 164 pregnant women were included, of whom 78 (47.56%) were nulliparous. COVID-19 was diagnosed before 28 weeks’ gestation in 30 (18.29%), while 134 (81.71 %) were diagnosed at or after 28 weeks’ gestation. Sixty-two (37.80%) women received at least one dose of COVID-19 vaccine. There were no significant differences between vaccinated and unvaccinated groups in the time interval between COVID-19 diagnosis and delivery, the Ct value, and the gestational age at infection onset or delivery (P > 0.05). The majority of women were symptomatic at diagnosis regardless of vaccination status (55 (88.71%) in vaccinated groupvs. 78 (76.47%) in unvaccinated group (P = 0.052). Symptoms did not significantly differ between groups except for cough (62.90%vs. 47.06%,P = 0.049). The overall
