The e-book: “Collection: Applied chemical engineering” consists of ten book chapters that were organized and divided into four thematic units, namely: i) natural products: extraction and purification of active principles; ii) development of new materials: study, comparison, different properties and applications; iii) use of analytical instruments for food quality control and; iv) development and application of bioadsorbents and advanced treatment technologies to remove contaminants from aquatic matrices.

The first theme presents two studies that evaluated the extraction of essential oil from the Baru species plant (Dipteryxalata Vog.) with nematicidal activity in combating Meloidogyne javanica. The second work evaluated triterpene purification processes from plant bioactives of Amazonian species. The second theme consists of three book chapters aimed at the study and comparison of natural, glass and mixed fibers for future applications; preparation of graphene oxides for production as composites in the form Cu/TiO2/rGO and estimates of thermodynamic properties of esters used in the production of biodiesel using a Gaussian software associated with the Constantinou and Gani group method. 

The third thematic unit consists of two works, one using the UV-Vis spectrophotometry technique to quantify the metallic ions of cadmium, copper, chromium, mercury, nickel and lead in cheeses produced by hand on rural properties; the second work evaluated the Kombucha probiotic and its importance in fermented foods. Finally, the fourth and last theme consists of three works with different approaches. The first deals with the possible environmental impacts that can be caused to water and soil as a result of exposure to Fracking gas present in Mexico. The second presents the study of the adsorption capacity from the biomass generated by the Andiroba species (Carapaguianensis Aubl.) in the removal of copper ions present in wastewater from industrial activities. The third chapter presents the study of the influence of the complexity of different aqueous matrices on the degradation of a mixture of drugs using the solar photolysis processes, TiO2/Solar and its combination with the addition of H2O2. This process constitutes one of the advanced treatment technologies to be made feasible on a large scale as a complementary step to conventional water and sewage treatment processes. 

In this perspective, Atena Editora has been working with the aim of stimulating and encouraging both Brazilian researchers and those from other countries to publish their work with quality assurance and excellence in the form of books, book chapters and articles that are available in the Editora's website and other digital platforms with free access.
