The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here. Core elements of this classification are some recent IUPAC definitions referring to the electrophile.

Ongoing efforts to discover new catalysts in coupling reactions have provided an effective toolkit for chemists over the last decades. However, metal impurities often lead to costly misinterpretations and reproducibility issues. Our guideline provides a practical roadmap for identifying true catalysts, eliminating impurity-driven errors, and ensuring reliable research outcomes. Designed primarily for handling trace metal challenges, this framework sets a new standard for robust, impurity-free catalyst discovery.

In this scientific perspective, we intend to provide a coherent framework for the field of magnetocatalysis by highlighting opportunities associated with the use of magnetic fields to activate catalysts. A particular focus will be placed on magnetically induced catalysis, providing an overview on current advances and identifying scientific and technical challenges on the path toward a widespread use of this technology in research and industry.

What are the tasks of chemical process development in the pharmaceutical industry? What are trends and challenges? This Scientific Perspective written by members of the European pharmaceutical industry introduces key concepts of drug development and key drivers for the future of chemical process development.

Photocatalytic CO₂ reduction to CH₃OH, particularly using metal-organic framework (MOF) photocatalyst, has received considerable attention due to its long-term potential to harness sunlight for converting CO₂ into this valuable fuel. This Perspective outlines the best practices that to provide robust and convincing evidence that CO₂ is the source of CH₃OH in the photocatalytic reactions.
