Reservoir Computing Physically implemented reservoir computing systems have aroused wide interest, due to their capability of efficiently handling temporally complex information. In article number 2108826, Ru Huang, Yuchao Yang, and co-workers present a multilayer system using ferroelectric In2Se3 as the key function material, which enables hierarchical information-processing that is suitable f...

A multilayer film of (Pd(2+)/)10 was simply fabricated by Pd(ii) and 2-Br-2',7,7'-tri(4-pyridyl)-9,9'-spirobifluorene (, Br-tpsf) through a layer-by-layer self-assembly method. The film loaded on a quartz slide as a catalyst reservoir could gradually release high active catalytic species to promote Sonogashira, Heck and Suzuki cross-coupling reactions, with extremely low Pd-loading of 11.0 × 10...

Multilayer diffusion and capillary condensation of propylene on supported y-alumina films greatly improved the permeability and selectivity. Multilayer diffusion, occurring at relative pressures of 0.4 to 0.8 strongly increased the permeability to 6 times the Knudsen permeability, yielding permeabilities of 3.2 x 10m5 mol/m’-see-Pa. The occurrence of a maximum in the permeability coincides with...
