Abstract Synthesis of structurally controlled graphene materials is critical for realizing their practical applications. The electrochemical exfoliation graphite has emerged as a simple method to produce materials. This review examines research progress in the last 5 years, from 2015 2019. Graphene material synthesis methods generally have trade‐off between increasing production yield and achieving better property control. conditions synthesizing pristine graphene, oxide (GO), composites are...
Flexible zinc-air batteries (ZAB) are a promising battery candidate for emerging flexible electronic devices, but the catalysis-based working principle and unique semi-opened structure pose severe challenge to their overall performance at cold temperature. Herein, we report first rechargeable ZAB with excellent low-temperature adaptability, based on innovation of an efficient electrocatalyst offset electrochemical shrinkage caused by decreased temperature highly conductive hydrogel polarized...
Metal–nitrogen–carbon (M–N–C) single-atom catalysts (SACs) show high catalytic activity for many important chemical reactions. However, an understanding of their intrinsic remains ambiguous because the lack well-defined atomic structure control in current M–N–C SACs. Here, we use covalent organic framework SACs with identical metal coordination environment as model to elucidate various centers A pH-universal trend is discovered among six 3d transition metals hydrogen peroxide (H2O2)...
Abstract Emerging wearable electronics require flexible energy storage devices with high volumetric and power densities. Fiber‐shaped capacitors (FCs) offer densities excellent flexibility but low Zn‐ion have density other advantages, such as cost, nontoxicity, reversible Faradaic reaction, broad operating voltage windows. However, not been applied in due to the use of liquid electrolytes. Here, first quasisolid‐state hybrid FC (ZnFC) based on three rationally designed components is...
Two-dimensional covalent organic frameworks (2D-COFs) may serve as an emerging family of catalysts with well-defined atomic structures. However, the severe stacking 2D nanosheets and large intrinsic bandgaps significantly impair their catalytic performance. Here, we report coaxial one-dimensional van der Waals heterostructures (1D vdWHs) comprised a carbon nanotube (CNT) core thickness tunable thienothiophene-pyrene COF shell using solution-based in situ wrapping method. Density functional...
Abstract Compactness and versatility of fiber‐based micro‐supercapacitors (FMSCs) make them promising for emerging wearable electronic devices as energy storage solutions. But, increasing the capacity microscale fiber electrodes, while retaining their high power density, remains a significant challenge. Here, this issue is addressed by incorporating ultrahigh mass loading ruthenium oxide (RuO 2 ) nanoparticles (up to 42.5 wt%) uniformly on nanocarbon‐based microfibers composed largely holey...
The standard training algorithm in neural machine translation (NMT) suffers from exposure bias, and alternative algorithms have been proposed to mitigate this. However, the practical impact of bias is under debate. In this paper, we link another well-known problem NMT, namely tendency generate hallucinations domain shift. experiments on three datasets with multiple test domains, show that partially blame for hallucinations, Minimum Risk Training, which avoids can Our analysis explains why...
Abstract Covalent‐organic frameworks (COFs) are emerging organic crystalline materials with a porous framework that extends into two or three dimensions. Originating from their versatile and rigorous synthesis conditions, COFs have abundant tunable pores, large easily accessible surfaces, plenty of redox‐active sites, making them promising material candidates for various energy storage applications. One important area is to serve as capacitive electrode in supercapacitors. This review...
In compressed sensing, one takes samples of an N -dimensional vector using matrix A , obtaining undersampled measurements . For random matrices with independent standard Gaussian entries, it is known that, when k -sparse, there a precisely determined phase transition: for certain region in the ( )-phase diagram, convex optimization typically finds sparsest solution, whereas outside that region, fails. It has been shown empirically same property—with transition location—holds wide range...
Core-periphery trading networks arise endogenously in over-the-counter markets as an equilibrium balance between trade competition and inventory efficiency. A small number of firms emerge core dealers to intermediate trades among a large peripheral firms. The depends on two countervailing forces: (i) their pricing immediacy firms, (ii) the benefits concentrated intermediation for lowering dealer risk through dealers' ability quickly net purchases against sales. For asset with lower frequency...

Abstract Metal halide perovskite solar cells (PSCs) have emerged as promising next‐generation photovoltaic devices with the maximum output efficiency exceeding 25%. Despite significant advances, there are many challenges to achieve high efficiency, stability, and low‐cost simultaneously. Combating these depends on developing novel materials modifying conventional device components. Carbon nanotubes (CNTs) attracted considerable attention for fabricating efficient PSCs owing their remarkable...
