Coupling ion exclusion and interaction screening within sub-nanoconfinement channels in novel porous material membranes hold great potential to realize highly efficient ion sieving, particularly for high-performance lithium-ion extraction. Diverse kinds of advanced membranes have been previously reported to realize this goal but with moderate performance and complex operations gained. Herein, these issues are circumvented by preparing the consecutive and intact imine-linked three-dimensional covalent organic framework (i.

Ion/electron-coupling logic operation is recognized as the most promising approach to achieving in-depth brain-inspired computing, but the lack of high-performance ion/electron-coupling devices with high operating frequencies much restricts the fast development of this field. Accordingly, we herein report an orthorhombic niobium pentoxide (T-Nb2O5) based lithium-ion capacitor diode (CAPode) that possesses thoroughly improved performances to achieve multifrequency ion/electron-coupling logic operations. Specifically, benefiting from the unique crystal structure and fast ion-transport topology of T-Nb2O5, the constructed CAPode exhibits a high response frequency of up to 122 Hz, over three orders of magnitude higher than those of the state-of-the-art CAPodes.

The rising demand for energy storage calls for technological advancements to address the growing needs. In this context, sodium-ion (Na-ion) batteries have emerged as a potential complementary technology to lithium-ion batteries (Li-ion). Among other materials, NaV(PO)F (NVPF) is a promising cathode for Na-ion batteries due to its high operating voltage and good energy density.

The most commonly used homogeneous catalyst for fatty acid esterification is a corrosive sulphuric acid. However, this requires costly investment in non-corrosive equipment, presents a safety risk, is time consuming, and increases effluent generation. In this study, inorganic 3D heteroborane cluster strong acids are employed for the first time as homogeneous catalysts.
