Scalable Platform Enabling Reservoir Computing With Nanoporous Oxide Memristors for Image Recognition and Time Series Prediction

Advanced Intelligent Systems, EarlyView.
The approach of physical in materia computing incorporates parallel computing within the medium itself. A scalable and energy‐efficient, oxide‐based computational platform is realized in form of a nanoporous network of volatile niobium oxide memristors sandwiched between top and bottom metallic electrodes, and then tested for prediction and ...

Fabrication of high quality ferromagnetic Josephson junctions

, 2005
We present ferromagnetic Nb/Al2O3/Ni60Cu40/Nb Josephson junctions (SIFS) with an ultrathin Al2O3 tunnel barrier. The junction fabrication was optimized regarding junction insulation and homogeneity of current transport.

F-doped orthorhombic Nb2O5 exposed with 97% (100) facet for fast reversible Li+-Intercalation

Green Energy & Environment
Orthorhombic Nb2O5 (T-Nb2O5) is attractive for fast-charging Li-ion batteries, but it is still hard to realize rapid charge transfer kinetics for Li-ion storage. Herein, F-doped T-Nb2O5 microflowers (F-Nb2O5) are rationally synthesized through topotactic

Size induced metal insulator transition in nanostructured Niobium thin films: Intragranular and intergranular contributions

, 2006
With a reduction in the average grain size in nanostructured films of elemental Nb, we observe a systematic crossover from metallic to weakly-insulating behavior.

Recent Strategies Toward Durable and Ion‐Tolerant Transition Metal‐Based Electrocatalysts in Seawater Electrolysis

Carbon Energy, EarlyView.
Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...
