Determining students' views on digital competency training needs
In this study, it is aimed to determine the views of primary school 4th grade students on digital competence training needs. In the research, phenomenology (phenomenology) design, one of the qualitative research designs, was used. The study group of the research consisted of 7 students in a primary school in Fatih district of Istanbul in the 2021-2022 academic year. The data of the research were obtained with the semi-structured interview form applied to the students. Content analysis was used to analyze the answers of the students in the interview forms, first the data were coded, and then the categories (themes) that explained the data at a general level were determined. The related literature, interview questions and the answers given by the students to the questions were used to determine the themes. From the analysis of the data, four themes were identified: virus, citing the source, unwanted content, pirated product, and not knowing the notification addresses
Synthesis and characterization of Ba/MCM-41
Mesoporous Ba/MCM-41 type materials (Ba/MCM-41) with high Ba/Si molar ratios between 0.025 and 0.1 were synthesized by direct hydrothermal synthesis. The samples were characterized by XRD, nitrogen adsorption, TGA-DTA, FTIR, SEM-EDS, and TEM techniques. BET surface areas of samples with various Ba loadings were found between 722 and 931 m(2)/g with 28 A average pore size, which is consistent with the pore size of 30 A for pure MCM-41 samples synthesized by the same procedure. The crystal structures of synthesized MCM-41 and Ba/MCM-41 were confirmed by XRD analysis. Among the investigated Ba/MCM-41 samples, the formation of barium oxide and barium nitrate species besides silicates was also observed in the high angle region XRD patterns
