Herein, we describe how video games, TV shows, or movies have been used to provide an innovative framework for students to think about chemistry and chemical engineering. The main objective of this paper is to show how science can be linked with pop-culture, to provide educators with recent materials to use in classrooms, and to […]
The influence of viscosity and surface tension on oxygen transfer was investigated using planar laser-induced fluorescence with inhibition (PLIF-I). The surface tension and the viscosity were modified using Triton X-100 and polyacrylamide, respectively. Changes in the hydrodynamic parameters of millimetric bubbles were identified, and transfer parameters were calculated. The results revealed a decrease in the […]
Over 1.7 billion students around the world have had their education disrupted by the spread of the Coronavirus disease worldwide. Schools and universities have not faced this level of disruption since World War II. The COVID-19 pandemic presented a colossal challenge for teachers to urgently and massively adapt all their classes to distance learning in […]
The purpose of this study is to present a learning activity that combines the simultaneous practice of geography and chemistry. It is a game activity based on the identification of national flags and colored molecules (from the famous CPK model), with an extension to the creation of imaginary flags from real, useful molecules for middle […]
Gamification is a widespread phenomenon that relies on using game mechanics in other areas, such as the learning situation. One of the most exciting types of games in the late 2010s is escape games, where the principle is for the players to manage to escape from a room in which they are locked by finding hidden […]
In a world engaged in a perpetual race for progress, augmented reality (AR) is a new frontier that has attracted much research attention in recent years. The generalization of smartphones and the miniaturization and democratization of connected gadgets are leading to new uses and new expectations. In this article, we provide an AR application to […]
Ozone is known to be a powerful oxidant with low persistence and has been shown to possess biocidal activity against a wide number of fungi and bacteria. These properties make ozone a good candidate as a substitute for chemical phytosanitary products in agriculture. However, when water containing dissolved ozone is sprayed, the concentration of ozone […]
Abstract Gas–liquid mass transfer was investigated around Taylor bubbles flowing in a long, in-plane, spiral-shaped milli-reactor involving various configurations. Using a colorimetric technique and image post-treatment, the variation of the equivalent O2 concentration inside the liquid slugs was measured. The coloration positions, corresponding to 99% of the maximum concentration reached in the liquid slug, changed significantly […]
Abstract An experimental investigation of gas–liquid Taylor flows in a millimetric in-plane spiral shaped reactor with various tube curvature ratios (52 < λ < 166) is reported. Thanks to the compactness of the reactor and the use of an ad hoc imaging system and processing, the axial evolution of bubble lengths and velocities could be […]
Abstract: In this activity, we describe how the TV show The Simpsons provides a nice opportunity for students to think about chemistry. The character’s name in the show is a good opportunity to help students memorize the elements from the periodic table. A list of the 118 existing elements associated with a character from the series is […]
