Metastable Polymers for Circular 3D Printing
Advanced Materials, EarlyView.3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Enhanced Mechanical Recycling of Polymer Mixtures by a Trifunctional Dynamic Crosslinker
Advanced Materials, EarlyView.A self‐catalyzed, trifunctional dynamic crosslinker that incorporates three desired properties into one system and is compatible with reactive extrusion can compatibilize waste plastic mixtures containing high Tm polymers and impart the recycled mixtures with superior thermoset properties such as enhanced creep resistance and thermomechanical stability

We have found a chameleonic reactivity of imidoyl sulfoxonium ylides. On the one hand, imidoyl sulfoxonium ylides react with electron-deficient reagents, such as alkynyl esters, to lead to the formation of 1,2-dihydro-pyridines. The methyl group attached

Advanced Materials, EarlyView.Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...

Route to Highly Substituted Pyridines
, 2016 Pyridine rings are common structural motifs found in a number of biologically active compounds, including some top-selling pharmaceuticals. We have developed a new approach to access substituted pyridines.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation
Advanced Materials Interfaces, EarlyView.Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.
