Adjusting the defect level during synthesis of A- and B-site deficient lanthanum iron manganite (LFM) perovskites shows that non-stoichiometry can beneficially influence catalytic reactivity to N2 in reduction NO by CO on noble metal-free LFM-based perovskites. Optimal steering La deficiency associated redox chemistry reduce near-surface regions operation at low temperatures is key factor. Surface enrichment reducible B site cations a proper design structural defects resulting from optimum...
The sintering behavior of OMS COK-12 into mechanically stable, porous monoliths was analyzed, including a customized multi-scale SAXS model.
Ceramic dielectrics with particularly low levels of dielectric loss and permittivity are growing interest toward millimeter‐wave applications. Based on composition structural considerations, lithic kosmochlor is expected to meet these requirements while exhibiting densification temperatures, allowing its integration also in co‐fired circuits. Herein, it found that the spark plasma sintering LiCrSi 2 O 6 ceramics facilitates at temperatures more than 200 °C lower conventionally processed...
Abstract Hierarchically porous, high‐surface‐area silica materials are excellent candidates for multiple applications like catalysis and environmental remediation. Shaping these with additive manufacturing (AM) techniques, robocasting, could enable their use the benefit of on‐demand, customized shaping maximizing performance. Herein, ordered mesoporous COK‐12 slurries were robocasted into monoliths, containing different ratios uncalcined sodium bentonite (0–25 wt.%). The rheology mixed is...
