Since its launch a little over three years ago, Chem has established itself as one of the most important journals in chemistry, reporting significant discoveries in fundamental and applied research each month. Many published Chem papers have already been instrumental in establishing new research fields and in identifying intriguing conceptual advances, and the journal is playing an integral role in showcasing the true impact of chemistry on tomorrow's world. Free Access to the Editors' Favorite Chem Articles from 2019 We asked the editors of Chem to tell us which were their favorite articles of 2019. Read the papers below. Robert D. Eagling, PhD Editor-in-Chief [CO2 Capture via Crystalline Hydrogen-Bonded Bicarbonate Dimers]( Radu Custelcean et al. “I loved the simplicity of this research. A known ligand first reported in 1898 is shown to remove CO2 from flue gas. Heat the complex a little and voila! H20 and CO2 are released, the CO2 cycle is complete, and the ligand is regenerated.” [Distinctive Two-Step Intercalation of Sr2+ into a Coordination Polymer with Record High 90Sr Uptake Capabilities]( Shuao Wang et al. [An Auxiliary Approach for the Stereoselective Synthesis of Topologically Chiral Catenanes]( Stephen M. Goldup et al. Ilaria Cianchetta, PhD Scientific Editor [The Electronic Structure of Lutein 2 Is Optimized for Light Harvesting in Plants]( Gabriela S. Schlau-Cohen et al. “I think it’s exciting when scientists reveal the mechanism of the processes that nature has mastered, like photosynthesis. Hopefully, we will be able to use this knowledge to produce more efficient and sustainable technologies in the future.” [Remote Control of Chemistry in Optical Cavities]( Joel Yuen-Zhou et al. [Superionic Diffusion through Frustrated Energy Landscape]( Geoffroy Hautier et al. Fenglin Liao, PhD Scientific Editor [Efficient and Selective CO2 Reduction Integrated with Organic Synthesis by Solar Energy]( Li-Zhu Wu et al. “This is an exciting photocatalytic system of simultaneously achieving CO2-to-CO conversion and oxidative coupling of organic molecules, in which both photogenerated electron and holes on the catalyst are well utilized. The elimination of holes by the oxidative coupling reaction not only avoids the addition of expensive sacrificial agents but also increases the stability of the whole system.” [Precisely Tuning the Number of Fe Atoms in Clusters on N-Doped Carbon toward Acidic Oxygen Reduction Reaction]( Yujie Xiong et al. [Beyond the Thermal Equilibrium Limit of Ammonia Synthesis with Dual Temperature Zone Catalyst Powered by Solar Light]( Lizhi Zhang et al. Vjekoslav Dekaris, PhD Scientific Editor [Direct Dearomatization of Pyridines via an Energy-Transfer-Catalyzed Intramolecular [4+2] Cycloaddition]( Frank Glorius et al. “This paper from the Glorius lab combines both fundamentally interesting chemistry and potential relevance for bigger picture applications as it tackles the dearomatization of pyridines, a challenging problem in organic synthesis. Application of this chemistry to build molecular complexity in pharmaceutically relevant nitrogen heterocycles could be interesting for industry.” [Precise Placement of Single Monomer Units in Living Ring-Opening Metathesis Polymerization]( Yan Xia et al. [Merging Photoredox PCET with Ni-Catalyzed Cross-Coupling: Cascade Amidoarylation of Unactivated Olefins]( Gary A. Molander et al.
