Phase Equilibria of the Ag-Al-Au Ternary System and Interfacial Reactions in the Au-Ag/Al Couples at 450 °C.

The phase equilibria of the Ag-Al-Au ternary system and the solid-state reaction couple for the Au-Ag/Al system were investigated isothermally at 450 °C. By investigating the Ag-Al-Au ternary system and its isothermal section, this study aims to provide a clearer understanding of the phase stability and interfacial reactions between different phases. This information is crucial for designing materials and processes in electronic packaging, with the potential to reduce costs and improve reliability.

Survey data of COVID-19-related knowledge, attitude, and practices among indonesian undergraduate students.

The dataset presented in this paper is an examination of COVID-19-related knowledge, attitude, and practice among Indonesian undergraduate students. The data were collected during first month of college or university closure due to COVID-19 through a survey distributed via an online questionnaire, assessing sociodemographic information (6 items), knowledge (18 items), attitude (6 item), and practice (12 items), from 27 April and 2 May 2020, gathering a total of 6,249 responses. A combination of purposive and snowball techniques helped to select the respondents via Whatsapp from more than ten universities in Indonesia.
