Neuromorphic computing has the potential to accelerate high performance parallel and low power in-memory computation, artificial intelligence, adaptive learning. Despite emulating basic functions of biological synapses well, existing electronic synaptic devices have yet match softness, robustness, ultralow consumption brain. Here, we demonstrate an all-inorganic flexible synapse enabled by a ferroelectric field effect transistor based on mica. The device not only exhibits excellent...
Abstract Flexible ferroelectric field effect transistors (FeFETs) with multiple functionalities and tunable properties are attractive for low power sensing, nonvolatile data storage, as well emerging memristor applications such artificial synapses, though the state‐of‐art flexible FeFETs based on organic materials possess polarization, large coercivity, high operating voltage, suffer from poor thermal stability.

AISI 420 martensitic stainless steel with excellent corrosion resistance is an ideal choice for plastic injection molds. However, molds are easy to fail in high–intensity and high-pressure environments. Therefore, it's necessary improve their hardness tensile strength prolong the service life of In this work, Selective laser melting (SLM), additive manufacturing technology was utilized process 5 wt% TiC/AISI composites. The influence volumetric energy density (η) on relative density,...
Triply periodic minimal surface (TPMS) structures prepared by additive manufacturing (AM) have been widely used in aerospace and thermal management systems due to their functional advantages such as high specific strength excellent heat transfer coefficient. However, lattices with uniform or simple gradients cannot match the regional diversity needs of service. This study proposed a field-driven AM data processing framework for dual functionally graded TPMS lattices. For unified processing,...

Abstract The functionalities and applications of oxide thin films are highly dependent on their thickness. Most thickness‐dependent studies require the preparation independent samples, which is labor‐intensive time‐consuming inevitably introduces experimental errors. To address this challenge, a general strategy based high‐throughput pulsed laser deposition technology proposed to precisely control thin‐film thickness in local regions under similar growth conditions. as‐proposed synthesis...
The primary purpose of this paper is to study intergranular and transgranular crack propagation behavior at the grain boundary (GB) Ni/Ni3Al by Molecular Dynamics (MD) simulation. Cracks are loaded in tension mode I. stress–strain curves, changes dislocation network, speeds interfacial energy compared with those two models. results show that yield stress model greater than model. It found does not extend along GB, but extends into γ′ phase. In addition, an angle 45° moves on slip system {11}...
Flexible energy storage based on ferroelectric capacitors enjoys high power density and rapid respond time, but the polarization fatigue problems limit its long-term reliability.

Nevertheless, of BNT thin films are restricted by their poor efficiency low density. In this work, flexible different numbers SrTiO3 (STO) insert layers fabricated mica substrates an...
Surface microstructure preparation offers a promising approach for overcoming the shortcomings of Al alloy, such as poor friction resistance, low hardness and weak corrosion resistance to corrosive liquid. Though many methods surface alloy have been developed, it is difficult most reported regulate as-prepared microstructure, meaning that properties cannot be improved efficiently by microstructure. Thus, application technology severely limited. Aimed at this issue, simple, convenient,...
