AbstractThe energy crisis has arisen as the most pressing concern and top priority for policymakers, with buildings accounting for over 40% of global energy consumption. Currently, single‐function envelopes cannot satisfy energy efficiency for next‐generation buildings. Designing buildings with high mechanical robustness, thermal insulation properties, and more functionalities has attracted worldwide attention. Further optimization based on bioinspired design and material efficiency improvement has been adopted as effective approaches to achieve satisfactory performance. Herein, inspired by the strong and porous cuttlefish bone, a cement aerogel through self‐assembly of calcium aluminum silicate hydrate nanoparticles (C‐A‐S‐H, a major component in cement) in a polymeric solution as a building envelop is developed. The as‐synthesized cement aerogel demonstrates ultrahigh mechanical performance in terms of stiffness (315.65 MPa) and toughness (14.68 MJ m−3). Specifically, the highly porous microstructure with multiscale pores inside the cement aerogel greatly inhibits heat transfer, therefore achieving ultralow thermal conductivity (0.025 W m−1 K−1). Additionally, the inorganic C‐A‐S‐H nanoparticles in cement aerogel form a barrier against fire for good fire retardancy (limit oxygen index, LOI ≈ 46.26%, UL94‐V0). The versatile cement aerogel featuring high mechanical robustness, remarkable thermal insulation, light weight, and fire retardancy is a promising candidate for practical building applications.

AbstractBenefitting from the maximum atom utilization efficiency, special size quantum effects and tailored active sites, single‐atom catalysts (SACs) have been promising candidates for bifunctional catalysts toward water splitting. Besides, due to the unique structure and properties, some amorphous materials have been found to possess better performance than their crystalline counterparts in electrocatalytic water splitting. Herein, by combining the advantages of ruthenium (Ru) single atoms and amorphous substrates, amorphous molybdenum‐based oxide stabilized single‐atomic‐site Ru (Ru SAs‐MoO3−x/NF) catalysts are conceived as a self‐supported electrode. By virtue of the large surface area, enhanced intrinsic activity and fast reaction kinetics, the as‐prepared Ru SAs‐MoO3−x/NF electrode effectively drives both oxygen evolution reaction (209 mV @ 10 mA cm−2) and hydrogen evolution reaction (36 mV @ 10 mA cm−2) in alkaline media. Impressively, the assembled electrolyzer merely requires an ultralow cell voltage of 1.487 V to deliver the current density of 10 mA cm−2. Furthermore, such an electrode also exhibits a great application potential in alkaline seawater electrolysis, achieving a current density of 100 mA cm−2 at a low cell voltage of 1.759 V. In addition, Ru SAs‐MoO3−x/NF only has very small current density decay in the long‐term constant current water splitting test.

AbstractThe liver plays a central role in regulating glucose and lipid metabolism. Aberrant insulin action in the liver is a major driver of selective insulin resistance, in which insulin fails to suppress glucose production but continues to activate lipogenesis in the liver, resulting in hyperglycemia and hypertriglyceridemia. The underlying mechanisms of selective insulin resistance are not fully understood. Here It is shown that hepatic membrane phospholipid composition controlled by lysophosphatidylcholine acyltransferase 3 (LPCAT3) regulates insulin signaling and systemic glucose and lipid metabolism. Hyperinsulinemia induced by high‐fat diet (HFD) feeding augments hepatic Lpcat3 expression and membrane unsaturation. Loss of Lpcat3 in the liver improves insulin resistance and blunts lipogenesis in both HFD‐fed and genetic ob/ob mouse models. Mechanistically, Lpcat3 deficiency directly facilitates insulin receptor endocytosis, signal transduction, and hepatic glucose production suppression and indirectly enhances fibroblast growth factor 21 (FGF21) secretion, energy expenditure, and glucose uptake in adipose tissue. These findings identify hepatic LPCAT3 and membrane phospholipid composition as a novel regulator of insulin sensitivity and provide insights into the pathogenesis of selective insulin resistance.
Revealing the Role of Zinc Ions in Atherosclerosis Therapy via an Engineered Three‐Dimensional Pathological Model

Published: April 2023

AbstractAn incomplete understanding of the cellular functions and underlying mechanisms of zinc ions released from zinc‐based stents in atherosclerosis (AS) therapy is one of the major obstacles to their clinical translation. The existing evaluation methodology using cell monolayers has limitations on accurate results due to the lack of vascular architectures and pathological features. Herein, the authors propose a 3D biomimetic AS model based on a multi‐layer vascular structure comprising endothelial cells and smooth muscle cells with hyperlipidemic surroundings and inflammatory stimulations as AS‐prone biochemical conditions to explore the biological functions of zinc ions in AS therapy. Concentration‐dependent biphasic effects of zinc ions on cell growth are observed both in cell monolayers and 3D AS models. Nevertheless, the cells within 3D AS model exhibit more accurate biological assessments of the zinc ions, as evidenced by augmented pathological features and significantly higher half‐maximal inhibitory concentration values against zinc ions. Based on such a developed 3D biomimetic AS model, the inhibitory effects on the deoxyribonucleic acid (DNA) synthesis, significantly influenced biological processes like cell motility, proliferation, and adhesion, and several potential bio‐targets of zinc ions of cells are revealed.

AbstractThe scarcity of high electrocatalysis composite electrode materials has long been suppressing the redox reaction of V(II)/V(III) and V(IV)/V(V) couples in high performance vanadium redox flow batteries (VRFBs). Herein, through ingeniously regulating the growth of Aspergillus Niger, a wrinkle‐like carbon (WLC) material that possesses edge‐rich carbon, abundant heteroatoms, and nature wrinkle‐like structure is obtained, which is subsequently successfully introduced and uniform dispersed on the surface of carbon fiber of graphite felt (GF). This composite electrode presents a lower overpotential and higher charge transfer ability, as the codoped multiheteroatoms increase the electrocatalysis activity and the wrinkled structure affords more abundant reaction area for vanadium ions in the electrolyte when compared with the pristine GF electrode, which is also supported by the density functional theory (DFT) calculations. Hence, the assembled battery using WLC electrodes achieves a high energy efficiency of 74.5% for 300 cycles at a high current density of 200 mA cm−2, as well as the highest current density of 450 mA cm−2. The WLC material not only uncovers huge potential in promoting the application of VRFBs, but also offers referential solution to synthesis microorganism‐based high‐performance electrode in other energy storage systems.

AbstractTo achieve energy saving and emission reduction goals, recyclable and healable thermoset materials are highly attractive. Polymer copolymerization has been proven to be a critical strategy for preparing high‐performance polymeric materials. However, it remains a huge challenge to develop high‐performance recyclable and healable thermoset materials. Here, polyimine dynamic networks based on two monomers with bulky pendant groups, which not only displayed mechanical properties higher than the strong and tough polymers, e.g., polycarbonate, but also excellent self‐repairing capability and recyclability as thermosets are developed. Owing to the stability of conjugation effect by aromatic benzene rings, the final polyimine networks are far more stable than the reported counterparts, exhibiting excellent hydrolysis resistance under both alkaline condition and most organic solvents. These polyimine materials with conjugation structure can be completely depolymerized into monomers recovery in an acidic aqueous solution at ambient temperature. Resulting from the bulky pendant units, this method allows the exchange reactions of conjugation polyimine vitrimer easily within minutes for self‐healing function. Moreover, the introduction of trifluoromethyl diphenoxybenzene backbones significantly increases tensile properties of polyimine materials. This work provides an effective strategy for fabricating high‐performance polymer materials with multiple functions.

AbstractMemristive devices are under intense development as non‐volatile memory elements for extending the computing capabilities of traditional silicon technology by enabling novel computing primitives. In this respect, interface‐based memristive devices are promising candidates to emulate synaptic functionalities in neuromorphic circuits aiming to replicate the information processing of nervous systems. A device composed of Nb/NbOx/Al2O3/HfO2/Au that shows promising features like analog switching, no electro‐forming, and high current‐voltage non‐linearity is reported. Synchrotron‐based X‐ray photoelectron spectroscopy and depth‐dependent hard X‐ray photoelectron spectroscopy are used to probe in situ different resistance states and thus the origin of memristive switching. Spectroscopic evidence for memristive switching based on the charge state of electron traps within HfO2 is found. Electron energy loss spectroscopy and transmission electron microscopy support the analysis. A device model is proposed that considers a two‐terminal metal–insulator–semiconductor structure in which traps within the insulator (HfO2/Al2O3) modulate the space charge region within the semiconductor (NbOx) and, thereby, the overall resistance. The experimental findings are in line with impedance spectroscopy data reported in the companion paper (Marquardt et al). Both works complement one another to derive a detailed device model, which helps to engineer device performance and integrate devices into silicon technology.

AbstractMemristive devices for neuromorphic computing have been attracting ever growing attention over the last couple of years. In neuromorphic electronics, memristive devices with multi‐level resistance states are required to accurately reproduce synaptic weights. Here, a memristive device based on a multilayer oxide system (Nb/NbOx/Al2O3/HfO2/Au), which features a filamentary‐free, homogenous interfacial resistive switching mechanism, is investigated. To gain a deeper insight into the switching mechanism, impedance spectroscopy (ImpSpec), X‐ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) are exploited. While this work focuses on the analysis of impedance and current‐voltage characteristics, XPS and TEM investigations can be found in a companion paper (Zahari et al.). In the course of this investigation, potentiodynamic impedance spectroscopy (PD‐ImpSpec) and time resolved impedance spectroscopy (TR‐ImpSpec) in combination with transient analysis are used. Evidence is presented of switching kinetics at voltages above 2.1 V directly related to changes in Schottky barrier resistance. These switching kinetics can in turn be interpreted by the charging and discharging of double positively charged oxygen vacancies ≈ 0.9 eV. The results of the impedance analysis are translated into a more general model for memristive devices to map the physical processes during switching.

AbstractParallel‐type organic electrochemical transistors (p‐OECTs) with aqueous electrolyte gate dielectrics have been widely studied for transducing biological signals into electrical signals. However, aqueous liquid electrolyte‐based p‐OECTs suffer from poor device stability, low transconductance (gm), and limited applications. In this study, a quasi‐solid‐state ion gel‐gated vertical‐type OECT (v‐OECT) and NOT logic gate are successfully demonstrated by combining both p‐type and n‐type v‐OECTs for the first time. Indacenodithiophene (IDT) polymers with alkyl (PIDTC16‐BT) and oligoethylene glycol (OEG) substituents (PIDTPEG‐BT) are studied as a channel material, and an ionic liquid in a crosslinked polymer matrix is adopted as a quasi‐solid electrolyte. Compared to aqueous devices, an enlarged electrochemical window and improved operational stability are observed. Notably, the v‐OECTs have a significantly larger channel area (50 × 50 µm2) and shorter channel length (≈30 nm), yielding a dramatically increased gm. As‐spun PIDTC16‐BT films exhibit a noticeably higher gm of 72.8 mS than that of previous p‐OECTs along with superior device stability, despite a low volumetric capacitance. In the case of v‐OECTs, face‐on intermolecular packing is required to increase the carrier transport in a vertical direction. Logic gates are successfully demonstrated using p‐ and n‐type v‐OECTs, suggesting the potential of OECT‐based next‐generation electronics.

AbstractMolecular devices have given impetus to the development of new electronic components. The transport process of organic molecules has a significant impact on device performance. Diketopyrrolopyrrole (DPPn, n = 1,2,3,4.) and derivative molecules have been widely explored due to their long‐range and efficient transport properties. In this paper, the electronic, optoelectronic, and thermoelectric properties of single diketopyrrolopyrrole molecular devices with different molecular units are investigated. By adjusting the bias voltage, the single molecular devices show a negative differential resistance effect, for which the reasons are given. Molecular orbital energy levels are regulated by gate voltages to enable conversion of conductivity. The transformation of molecular device functions in time‐varying alternating current transport is discussed in detail. Bias voltage regulation is performed for the molecular device optical response to produce better photocurrent, and finally the thermoelectric current of the device is also analyzed. This results reveal that single molecular electronic, optoelectronic, and thermoelectric properties are highly correlated with molecular unit‐length, which provides guidance for the development of molecular devices with different unit lengths.

AbstractThe essential step for developing neuromorphic systems is to construct more biorealistic elementary devices with rich spatiotemporal dynamics to exhibit highly separable responses in dynamic environmental circumstances. Unlike transistor‐based devices and circuits with zeroth‐order complexity, memristors intrinsically express some simple biomimetic functions. However, with only two‐terminal structure, precise control of operation principles to ensure large dynamic space, improved linearity and symmetry, multimodal operation as well as high‐order complexity is hard to achieve in a traditional memristor owing to its limited degree of freedom. Therefore, multiterminal memristors including both concrete terminals and virtual terminals (light, pressure, gas, ferroelectric polarity, etc.) have been proposed to obtain precise modulation of memristive characteristics. This review focuses on the recent progress in multiterminal memristors and their neuromorphic applications. The operation principle, application of multiterminal memristor on neuromorphic computing in different scenarios, existing challenges and future prospects are discussed.
Periodically Alternating Electric Field Layers Induces the Preferential Growth of Zn (002) Plane for Ultralow Overpotential Zinc‐Ion Batteries

Published: April 2023

AbstractThe sluggish de‐solvation kinetics and uneven Zn2+ transport behavior at the Zn anode are undesirable for commercialization of zinc ion batteries. To address these issues, a periodically alternating electric field is introduced on the Zn anode by constructing a laponite nano‐clay layer with unique electric field separation properties. This layer exhibits negative and positive electric fields together in the same space but in different directions (negative electric field in the normal direction while the positive electric field is in the radial direction); thus, achieving both homogeneous Zn2+ transport and an effective de‐solvation effect. The laponite film (LAP@Zn) as a multifunctional artificial layer can induce Zn2+ nucleation for preferential orientation growth of Zn along the (002) planes, thereby suppressing dendrite growth on the Zn anode. Consequently, the LAP@Zn symmetric cells exhibit an ultralow overpotential (12 mV) and cycle smoothly over 1100 h at 0.5 mA cm−2. Even at an ultrahigh current density of 40 mA cm−2, the cell still operates stably for 500 h. More encouragingly, the effectiveness is also convincing in MnO2‐based full cells with excellent rate performance and cycle stability. The periodically alternating electric field strategy provides an effective path toward high‐performance and dendrite‐free Zn‐based storage systems.

AbstractIncompatible interphases resulting from the irreconcilable contradiction between impedance and mechanical strength have become one of the major obstacles to the practical application of solid‐state lithium metal batteries (SSLMBs). With the employment of a decoupling strategy by rational topological design, herein a topological polymer‐reinforced interphase layer is in situ constructed using a synthesized solid polymer electrolyte. As a result, the constructed topological solid electrolyte interphase (SEI) layer harmonizes the enhanced mechanochemical stability and fast diffusion dynamics of Li+, which maintains the integrity and stability of the SEI layer during cycling. In addition, a highly stable and reversible Li nucleation/stripping behaviors exceeding 3000 h and the superior cycling performance of practical LiFePO4/Li metal battery beyond 500 cycles can be achieved by virtue of the formation of the topological interphase layer. This design strategy of constructing a topological interphase layer to decouple mechanical strength and the activation energy of Li+ transport provides a feasible paradigm for realizing practical SSLMBs.

AbstractGlobal warming and the energy shortage due to the burning of fossil fuels are two major challenges. A strategy of light‐driven catalytic dry reforming of methane (DRM) using inexhaustible solar energy has provided an effective approach to tackle these challenges. Loaded metallic Ni nanoparticles have been identified as promising catalysts as alternatives to noble metals for DRM. However, they suffer from quick deactivation caused by severe coking due to thermodynamically inevitable side‐reactions. Herein, a unique nickel half‐metal catalyst of monolayer nickel clusters stabilized by alumina is reported, with 100% atomic utilization efficiency and extraordinary catalytic performance for light‐driven DRM, dramatically different from its counterpart of conventional metallic Ni nanoparticles. It has extremely high specific H2 and CO production rates of 8572.96 and 9614.26 mmol min−1 gNi−1, more than one order of magnitude higher than those of Ni nanoparticles. No detectable coke is formed due to the alteration of kinetic processes for DRM, resulting in the inhibition of coke deposition. It is discovered that light not only significantly enhances catalytic activity, but also enables quick thermocatalytic deactivation to be durable due to the oxidation of carbon species and the desorption of strongly adsorbed CO2 and CO being dramatically promoted by light.
Building Up an “Elemental Property—Adsorption Energy Descriptor—Decomposition Barrier” Three‐Tier Model for Screening Biatom Catalysts in Sodium–Sulfur Batteries

Published: April 2023

AbstractDeveloping highly efficient catalysts for the Na2S redox process and sodium polysulfide anchoring is becoming increasingly important for high‐performance sodium–sulfur (Na–S) batteries. The recently emerged graphene‐supported biatom catalysts (G‐BACs) exhibit great potential for providing high activity in both discharging and charging processes. However, the fast screening of promising G‐BACs for Na–S batteries is hindered by the formidable computational cost for calculating Na2S decomposition barriers (Eb). Herein, this work develops an “elemental property—adsorption energy descriptor—decomposition barrier” three‐tier model to accelerate this process and elucidates the origin of catalytic activity. It is found that Eb during the charging process is linearly correlated with the adsorption energy difference between the initial and final states of Na2S decomposition (Ediff) for both homonuclear and heteronuclear transition metal G‐BACs. This work further correlates Ediff with intrinsic properties of metal elements by machine learning approaches and unravels the most significant elemental feature to be the outer electron number. This work not only accelerates the design of highly efficient G‐BACs in Na–S batteries based on the structure–activity relationship, but also provides a feasible strategy for the fast screening of catalysts for other electrochemical reactions for potential experimental design.
