School lockdown? Comparative analyses of responses to the COVID-19 pandemic in European countries
The Organisation for Economic Co-operation and Development (OECD, 2020) describes the closure of schools in different countries. Based on their reporting, Table 1 shows how many days the primary schools were closed during the spring of 2020. We have also included closures of secondary schools and confirmed COVID-19 cases per […]
Experiment to Teach Multiple Melting Phenomena in Semicrystalline Polymers Using Differential Scanning Calorimetry
Abstract This article describes a laboratory experiment used to investigate the phenomenon of multiple melting in polymers. The experiment is aimed at the level of senior undergraduate chemistry students able to carry out the investigation in a research-style approach, working together in small groups. The experiment highlights characteristic thermal behavioral […]
Spectrophotometric Investigation of Complexation of Ferrous Ion with 3,5-Dintrosalicylic Acid
Abstract The determination of stoichiometry and stability constant of metal-ligand complex holds great significance for chemical, physical, environmental and biological studies. In the present work, the stoichiometric ratio and stability constant of iron complex of 3,5-dinitrosalicylic acid was determined using Job’s method of continuous variation. Job’s method can be easily […]
