The effect of pore orientation and pore volume on the dielectric and piezoelectric properties as well as the piezocatalytic activity of lead‐free porous (Ba,Ca)(Ti,Zr)O3 (BCTZ) are investigated. The pore orientation in BCTZ is controlled using a freeze‐casting method. Two types of porous BCTZ samples, i.e., A‐BCTZ and B‐BCTZ, are prepared by cutting them in parallel and perpendicular directions, respectively, to the longitudinal pore direction. The samples with 30% porosity indicate that the permittivity of A‐BCTZ is 648, less than 1/3 of that of B‐BCTZ (2059). A‐BCTZ also exhibits the highest hydrostatic voltage coefficient (gh, 9.26 × 10−3 Vm N−1), which is approximately 1.7 times higher than B‐BCTZ and 50 times higher than the dense BCTZ sample. Photo–piezocatalytic effect is investigated by a methylene blue (MB) degradation test under UV light while applying ultrasonic wave, and the catalytic activity of the poled porous BCTZs shows much higher than the dense BCTZ by their large specific surface area. Thus, porous piezoelectric materials are promising as a semipermanently available catalyst to replace nanoparticles whose specific surface area is reduced likely by agglomeration.

Chiral Phosphoric Acid Catalysts Organocatalytic enantioselective aza‐Friedel–Crafts reactions of cyclic ketimines with pyrroles or indole were catalyzed by imidazolinephosphoric acid catalysts. The reaction was applied to various 3H‐indol‐3‐ones to afford products in excellent yields and enantioselectivities. The graphics shows origami cranes that fly with expanded wings. The bis(imidazoline)/phosphoric acid catalysts also expand their wings like the origami cranes, and form a well‐fitting asymmetric space for substrate binding to let the reaction “fly”. The full story can be found in the Communication by S. Nakamura and colleagues on page 9478 ff.
