In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators

Macromolecular Rapid Communications, EarlyView.
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...
