A series of unreported fullerodihydropyridine-3-ones were synthesized as a new family of fullerene derivatives in moderate to good yields by a simple one-step reaction of[60]fullerene with cheap and readily available β-substituted ethylamines in the absence or presence of arylacetaldehydes under the assistance of Cu(OAc)_(2).The in situ generation of arylacetaldehydes by the C—N bond cleavage of arylethylamines avoided their complex synthesis in advance and realized the preparation of fullerodihydropyridine-3-ones with structural and functional diversities,which may have promising applications in perovskite solar cells to improve the performance of photovoltaic devices due to the existence of a largeπ-conjugated system on the dihydropyridine-3-one ring.

Reservoir computing (RC) system, featured by its recursive structure, has been utilized for temporal signal processing, offering both low power consumption and high computational speed. This work reports on a novel input delay reservoir computing (ID-RC) system based on the oxide memristors, which can be applied to temporal signal prediction. The particle swarm optimization (PSO) algorithm is employed in the ID-RC system to obtain optimal hyperparameters for multi-step prediction in the Mackey-Glass task, with a normalized root-mean-square error (NRMSE) of only 0.09 at the 20th step. Significantly, by employing the ID-RC system in temporal signal prediction of the Hénon map and the nonlinear autoregressive moving average (NARMA10), small NRMSEs of 0.047 and 0.017 were achieved, respectively. The memristor-based ID-RC system turns out to be highly promising in forecasting of chaotic time series. © 2024, The Authors. All rights reserved.

Metal-organic frameworks (MOFs) derived metallic nanoparticles embedded nano-porous carbon (NPC)composites have shown to be promising microwave absorbing materials. Although MOF precursors withdiverse compositions and morphologies have been extensively investigated, anionic MOFs are rarelyexplored for this utility. In addition to the metal sites and ligands on the MOF framework, the guestcounter-cations in the void provide supplementary parameters to tune the capability of microwaveabsorption. Herein, we applied an anionic NixCoy-MOF featuring N-rich ligands and hierarchical porousstructures as a precursor for microwave absorption. The obtained dielectric-magnetic Ni_(x)Co_(y)@NPCcomposites with rich N dopants and multiple hetero-interfaces promote the microwave attenuationcapability through enhanced dipole/interfacial relaxation. The synergistic effects of magnetic loss andconduction loss induced by metallic nanoparticles (NPs) and porous graphitic layers further facilitate themicrowave dissipation. More significantly, impedance matching can be effectively improved by tuningthe Co/Ni amount in the precursors to realize the modulation of electromagnetic parameters. Conse-quently, Ni@NPC exhibits the optimal electromagnetic wave (EMW) absorption with minimum reflectionloss of 66 dB at only 2 mm and broad effective absorption band covering 4.56 GHz at a thin thickness of2.07 mm, making this material promising absorber for EMW elimination.
