This study aimed to explore the influence from environmental and urbanisation factors, and the spatial relationship between epidemiologically-linked, unlinked and imported cases during the early phase of the epidemic in Singapore. Spatial relationships were evaluated with GWR modelling. Community COVID-19 cases with residential location reported from 21st January 2020 till 17th March 2020 were considered for analyses. Temperature, relative humidity, population density and urbanisation are the variables used as exploratory variables for analysis. ArcGIS was used to process the data and perform geospatial analyses. During the early phase of COVID-19 epidemic in Singapore, significant but weak correlation of temperature with COVID-19 incidence (significance 0.5-1.5) was observed in several sub-zones of Singapore. Correlations between humidity and incidence could not be established. Across sub-zones, high residential population density and high levels of urbanisation were associated with COVID-19 incidence. The incidence of COVID-19 case types (linked, unlinked and imported) within sub-zones varied differently, especially those in the western and north-eastern regions of Singapore. Areas with both high residential population density and high levels of urbanisation are potential risk factors for COVID-19 transmission. These findings provide further insights for directing appropriate resources to enhance infection prevention and control strategies to contain COVID-19 transmission.</p>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"3 6","pages":"9758"},"PeriodicalIF":3.8,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9191550/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41309544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inner nitrogens can increase the electron density of d-bands of transition metals, so that the electronic structures of TMNs are similar with some precious metals, whose density of states can cross the Fermi level. Therefore, TMNs have similar conductivities with metals and possess superior electrocatalytic performance. Nanostructured TMNs tend to have relatively large dispersion and more exposed active sites, which have direct improvement for catalytic activity and stability as electrochemical catalysts. This review summarizes the representative progress of TMNs based catalysts on both synthetic strategies of structural engineering and electronic engineering for improving electrocatalytic performance, especially in hydrogen evolution, oxygen evolution and water splitting.

Nitrogen-doped nanocarbons are the even more attractive for the modified electronic structure and enhanced interaction with the supported species. With the assistance of N participation, metal catalysts have been constructed on N-doped nanocarbons from highly dispersed nanoparticles to sub-nanometer clusters and single sites.
