Among nitrogen-containing heterocyclic compounds, 1,2,3-triazoles are privileged structure motif and received a great deal of attention in academics and industry. Even though absent in nature, 1,2,3-triazoles have found broad applications in drug discovery, organic synthesis, polymer chemistry, supramolecular chemistry, bioconjugation, chemical biology, fluorescent imaging, and materials science. Therefore, the development of facile and straightforward methodology for the synthesis of 1,2,3-triazoles is of noteworthy interest. In this study, emphasis will be given to numerous synthetic approaches for the synthesis of 1,2,3-triazoles, especially the popular click chemistry approach. Furthermore, several biological activities of this promising heterocycle will also be discussed.

AbstractThe need for fast and low-cost processes for compound development is obvious when “bespoke” products are required in small quantities. In a typical development workflow, many experiments are needed for the systematic study of the effects of additives and their potential synergistic interactions. This is usually accomplished using the one-variable-at-a-time variational principle. However, if the complexity of the formulation is high, the number of experiments that needs to be conducted soon becomes prohibitive. Therefore, new, but potentially more effective additives are not easily introduced. To address this problem, the plastics processing industry is turning to the notion of combinatorics, which has been shown to accelerate R&D times both in the pharmaceutical industry as well as in other areas of materials science such as catalysis and polymer chemistry.The contribution discusses the development of a combinatorial compounding line, consisting of a production-size twin screw extruder with four gravimetric feeding units for the addition of additives. Furthermore, the development of fast on-line and in-line analytics for compound characterization is discussed.

AbstractThis issue of MRS Bulletin provides an overview of the state of the art and emerging trends in the area of adhesives. An adhesive is basically defined by its function, which is to assemble two surfaces together. In order to fulfill this function, the properties of an adhesive must include easy positioning at the interface, rapid and complete bond formation and subsequent hardening, and a bond strength adapted to the specific application (structural, permanent, removable, rigid, or soft). A variety of solutions exist in practice, and their application requires an understanding both of polymer chemistry and materials science. The main families of adhesives, their properties, and their basic design principles will be discussed in the articles in this issue, while this introductory article presents an overview of the functions required of adhesives and future trends.
