Research on Residual Gas Adsorption on Surface of Hexagonal Boron Nitride-Based Memristor.

As a promising nonvolatile memory device with two ends, the memristor has received extensive attention for its industrial manufacture. Density functional theory was used to analyze the adsorption properties of residual gas on hexagonal boron nitride (h-BN)-based memristor model surfaces with Stone-Wales-5577 grain boundary defects [h-BN(SW)]. First, by calculating the adsorption energy, geometric parameters, and charge transfer, we identified the most stable adsorption sites for hydrogen atoms (H-TB1) and H molecules (H-TN2).

Bimetallic ZIF-derived conductive network of Co-Zn@NPC@MWCNT nanocomposites for efficient electromagnetic wave absorption in the whole X-band.

Due to bimetallic MOFs (metal-organic frameworks) possessing diverse structure topologies and superior properties, herein, we used bimetallic ZIFs (zeolitic imidazole frameworks) of MOFs as precursors the wet chemical and calcination method to fabricate zinc-embellished Co-Zn@NPC@MWCNT nanocomposites with porous conductive carbon-based networks The abundant carbon defects, zinc evaporation, and N-atom doping resulted in the emergence of dipolar/interface polarization, which is good for dielectric loss. The high porosity and large specific surface area were instrumental in the attenuation of multiple scattering and endowed the absorber with an excellent absorption performance. With merely 15 wt% filled loading and 3.

Resilient bismuthene-graphene architecture for multifunctional energy storage and wearable ionic-type capacitive pressure sensor device.

A facile resilient bismuthine-anchored graphene architecture is reported as multifunctional all-solid-state flexible supercapacitors and ionic-type capacitive sensor. Meanwhile, an electrons/ions dual transport channels design is achieved by inserting elaborately conductive bismuthene flakes into hierarchical porous aerogel framework. This strategy concurrently realizes the expansion of interlayer space for favoring electrolyte infiltration, and boost of interlayer conductivity to ensure interlayer electrons transport, endowing the device with attractive electrochemical energy storage and pressure sensing performance.
