Abstract

The purpose of game-based learning is to design learning activities that introduce or explain concepts in more attractive way than in the traditional classroom. Using educational games in the classroom enables innovative and interactive lesson in which the material is seen from a different perspective or point of view. Play is connected to creativity, higher-order thinking, inquiring and problem-solving skills, decision making, collaboration, communication and the development of positive attitudes toward chemistry. The aim of this paper is to emphasize the importance of game-based learning approach in the classroom. Several good practice examples of games and puzzles for chemistry teaching are given to illustrate their applicability in the classroom and to serve as an idea for teachers, thus motivating them to be more creative in finding ways to implement this method and create their own puzzles according to their needs and classroom settings. Motivated by the International Year of the Periodic Table, puzzles are related to the Periodic Table concepts. The presented games can be used to create an escape room classroom, but they can be used independently. We believe that the use of games for educational purposes will be of great benefit to students.

Abstract

Chiral molecules hold a mail position in Organic and Biological Chemistry, so pharmaceutical industry needs suitable strategies for drug synthesis. Moreover, Green Chemistry procedures are increasingly required in order to avoid environment deterioration. Catalytic synthesis, in particular organocatalysis, in thus a continuously expanding field. A survey of more recent researches involving chiral imidazolidinones is here presented, with a particular focus on immobilized catalytic systems.

Abstract

In this chapter, a direct comparison of the performance of the most representative conventional microporous zeolites, amorphous mesoporous aluminosilicates and hierarchical (meso/macroporous) zeolites in catalytic fast pyrolysis (CFP) of biomass is presented, based on experiments performed under the same conditions in a bench scale fixed bed (down flow) reactor. Furthermore, a comprehensive overview of the state-of-the-art on biomass CFP with these types of catalysts is also included, aiming to highlight the most representative previously reported results. On the basis of both the experimental and literature data, it was shown/verified that biomass CFP with acidic micro/meso/macroporous materials can be effectively utilized for tuning the composition and properties of the bio-oil, depending on its targeted final use as source of chemicals (phenolics, aromatics), as fuel additive (aromatics) or as biocrude for downstream hydrodeoxygenation toward hydrocarbon fuels.
