Abstract Neuromorphic computing, which emulates the biological neural systems could overcome high‐power consumption issue of conventional von‐Neumann computing. State‐of‐the‐art artificial synapses made two‐terminal memristors, however, show variability in filament formation and limited capacity due to their inherent single presynaptic input design. Here, a memtransistor‐based artificial synapse is realized by integrating memristor selector transistor into multiterminal device using monolayer...
Abstract Recently, 2D ferroelectrics have attracted extensive interest as a competitive platform for implementing future generation functional electronics, including digital memory and brain‐inspired computing circuits. Fulfilling their potential requires achieving the interplay between ferroelectricity electronic characteristics on device operation level, which is currently lacking since most studies are focused verification of from different materials. Here, by leveraging semiconducting...

Recent advancements in printing techniques show enormous potential to overcome the major challenges current manufacturing processes that require high temperature planar topography, which may radically change system integration approach substrates. However, fully printed are yet be successfully demonstrated due lack robust printable switching...
Abstract Bulk photovoltaic effect (BPVE), featuring polarization-dependent uniform photoresponse at zero external bias, holds potential for exceeding the Shockley-Queisser limit in efficiency of existing opto-electronic devices. However, implementation BPVE has been limited to naturally materials with broken inversion symmetry, such as ferroelectrics, which suffer low efficiencies. Here, we propose metasurface-mediated graphene photodetectors cascaded polarization-sensitive under...
Two-dimensional ferroelectrics is attractive for synaptic device applications because of its low power consumption and amenability to high-density integration. Here, we demonstrate that tin monosulfide (SnS) films less than 6 nm thick show optimum performance as a semiconductor channel in an in-plane ferroelectric analogue device, whereas thicker have much poorer response due screening effects by higher concentration charge carriers. The SnS exhibits behaviors with highly stable...
In this study, a cost-effective calcium alginate-based ion-exchange resin (CABIER) was employed for treatment of metal waste streams. pH, concentration, and presence competitive ions played important roles in the removal. The X-ray photoelectron spectroscopy (XPS) Fourier transform infrared (FT-IR) analysis indicated that functional groups on carbohydrate backbone (i.e., C−O−R COO-1) were responsible binding metals. It found lead abstraction driven by ion exchange between Ca2+ Pb2+. On...
Zinc oxide (ZnO) hierarchical structures (HSs) have recently demonstrated notable photochemical and photovoltaic performances attributed to their nano/micro combined architectures. In this study, ZnO HSs were synthesized at room temperature using ultrarapid sonochemistry. This novel approach can effectively overcome deficiencies in the synthesis via traditional direct precipitation by promoting nucleation accelerating diffusion. Only 15 min was needed complete formation of highly...
Abstract Although polymers have been studied for well over a century, there are few examples of covalently linked polymer crystals synthesised directly from solution. One-dimensional (1D) covalent that packed into framework structure can be viewed as 1D organic (COF), but making single crystal this has elusive. Herein, by combining labile metal coordination and dynamic chemistry, we discover strategy to synthesise single-crystal metallo-COFs under solvothermal conditions. The is rigorously...
