The present technology report is aimed at demonstrating how the implementation of VR chemistry simulations of atomic structure enhances learning among students. MEL Chemistry VR lessons were incorporated into the classroom for 43 first-year undergraduate ITMO University students. The visualization techniques provided the learners with two important opportunities: (1) connecting the macroscopic and tangible component of chemistry with the submicroscopic component (the real world and the world of molecules) and (2) connecting the submicroscopic component of chemistry with the representational one (atomic structure and orbital diagrams). The results show that implementation of the VR experience into the atomic structure laboratory enhances the learning experience of the students.

Electrochemistry represents a powerful sustainable method for chemical synthesis; however, its widespread application is limited due to the lack of exposure and appropriate basic training of synthetic chemists and engineers in electrochemistry and electrochemical engineering. The introduction of diverse laboratory practices to the current curricula will improve the understanding of electrochemistry and the theory behind its various applications. Here, we suggest an efficient laboratory experiment on the electrochemical reduction of CO 2 to CO using inexpensive and readily available materials, such as metal wires, plastic vessels, batteries, and a handheld CO detector. Students learn to assemble a divided electrochemical cell and perform important electrochemical reactions, such as electrochemical CO 2 reduction and hydrogen evolution reaction.In this experiment, students analyze the rates of CO production under different electrolysis conditions and learn to understand the effects of operating parameters (applied potential, electrolyte concentration, and nature of the electrode) on the outcome of the reaction. This new comprehensive laboratory experiment is designed for students to better understand basic principles of electrochemistry and is suitable for undergraduate students.
