Temporal- and Spatial-Resolved Characterization of Zeolite-Based Catalysts

Abstract Zeolites and metal-zeolite catalysts are the cornerstones of heterogeneous catalysis, where performance is governed by the structural dynamics and spatial distribution of active sites. However, conventional characterization often lacks the spatiotemporal resolution neede...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...
