Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

Practical work in optics is essential to understand complex abstract phenomena. Consequently, hands-on experiments are part of most physics' curricula, despite the fact that they can be hard to set up and maintain. In this article, we present a virtual laboratory tool, called SHIRE, which allows students to carry out optical experiments from a…

The COVID-19 pandemic has accelerated the shift from traditional in-person teaching to remote and online learning, necessitating a more adaptable educational platform to serve the diverse needs of students. Transforming hands-on "wet lab" activities into virtual "dry lab" exercises can promote a more accessible and flexible…
