AbstractThis study proposes a strategy based on heterovalent ion doping that gives rise to a synergistic piezo‐phototronic effect with significantly improved catalytic activity and leads to selective catalytic enhancement for specific pollutants. Owing to the enhanced light absorption, hydrogen evolution rates are as high as 3704 and 3178 µmolg−1 h−1 in 0.01Li‐doped BaTiO3 and 0.02La‐doped BaTiO3 nanosheets, respectively, under simultaneous irradiation by ultrasound and light, a factor of 4.6 and 3.9 times higher than for pure BaTiO3. The performance also far exceeds that of single piezocatalysis, photocatalysis, or the sum of the two for Li/La‐doped BaTiO3 nanosheets due to the effects of the piezoelectric field in promoting photo‐induced separation of electron‐hole pairs. Further, by carefully selecting donor or acceptor doping, a significant enhancement in catalyst to specific pollutants is obtained by controlling the band structure. Compared to pure BaTiO3, 0.01Li‐doped BaTiO3 possesses higher catalytic activity for anionic dyes such as Methyl blue and Malachite Green, reaching 0.067 and 1.379 min−1, respectively, while 0.02La‐doped BaTiO3 exhibits better catalytic performance for cationic dyes such as Rhodamine B and Methyl Orange, with degradation rates up to 0.274 and 0.029 min−1, respectively. This study offers a path to the design of efficient piezocatalysts for specific applications.

AbstractStereoscopic 3D display devices have been developed toward integration and compactness. Metasurfaces have immeasurable advantages in the field of 3D display due to their tiny structures and flexible design capabilities. Here, a 3D multifocal display method based on stereoscopic metasurface (SMS) is proposed and demonstrated. Based on Dammann optimization method and Fourier expansion with zone plate to generate phase profile, such SMS can reorganize different planar images projected from Digital Mirror Device to form 3D images with correct depth clues. Thanks to the large Numerical Aperture of nano‐devices, total 20 multi‐focal planes can be independently used for display by considering dual polarization multiplexing. The experimental effects for stereoscopic arrangement of 3D number, letters, and several 3D images are demonstrated. Such compact‐scale SMSs have great potential to the applications of augmented/virtual reality devices, stereoscopic optical engraving, 3D optical manipulation, etc.

AbstractThe impact of the bulky‐cation‐modified interfaces on halide perovskite solar cell stability is underexplored. In this work, the thermal instability of the bulky‐cation interface layers used in the state‐of‐the‐art solar cells is demonstrated. X‐ray photoelectron spectroscopy and synchrotron‐based grazing‐incidence X‐ray scattering measurements reveal significant changes in the chemical composition and structure at the surface of these films that occur under thermal stress. The changes impact charge‐carrier dynamics and device operation, as shown in transient photoluminescence, excitation correlation spectroscopy, and solar cells. The type of cation used for surface treatment affects the extent of these changes, where long carbon chains provide more stable interfaces. These results highlight that prolonged annealing of the treated interfaces is critical to enable reliable reporting of performances and to drive the selection of different bulky cations.

AbstractHigh‐rate conversion of carbon dioxide (CO2) to ethylene (C2H4) in the CO2 reduction reaction (CO2RR) requires fine control over the phase boundary of the gas diffusion electrode (GDE) to overcome the limit of CO2 solubility in aqueous electrolytes. Here, a metal–organic framework (MOF)‐functionalized GDE design is presented, based on a catalysts:MOFs:hydrophobic substrate materials layered architecture, that leads to high‐rate and selective C2H4 production in flow cells and membrane electrode assembly (MEA) electrolyzers. It is found that using electroanalysis and operando X‐ray absorption spectroscopy (XAS), MOF‐induced organic layers in GDEs augment the local CO2 concentration near the active sites of the Cu catalysts. MOFs with different CO2 adsorption abilities are used, and the stacking ordering of MOFs in the GDE is varied. While sputtering Cu on poly(tetrafluoroethylene) (PTFE) (Cu/PTFE) exhibits 43% C2H4 Faradaic efficiency (FE) at a current density of 200 mA cm−2 in a flow cell, 49% C2H4 FE at 1 A cm−2 is achieved on MOF‐augmented GDEs in CO2RR. MOF‐augmented GDEs are further evaluated in an MEA electrolyzer, achieving a C2H4 partial current density of 220 mA cm−2 for CO2RR and 121 mA cm−2 for the carbon monoxide reduction reaction (CORR), representing 2.7‐fold and 15‐fold improvement in C2H4 production rate, compared to those obtained on bare Cu/PTFE.

Published: October 2022

AbstractDopamine (DA) and uric acid (UA) are biomolecules of great consideration that coexist in human body. It is essential and challenging to detect them simultaneously with high sensitivity. This paper reports a novel electrochemical biosensor based on the nanocomposites of cobalt phthalocyanine (CoPc) anchored with graphene quantum dots (GQDs) for DA and UA detection. The GQDs incorporation on CoPc nanorods with partial end stretching significantly enhances the electrocatalytic activity and promotes the electron transfer rate. Low detection limits of 21 nm for DA and 145 nm for UA have been successfully achieved for the fabricated CoPc/GQDs biosensor. The density‐functional theory proves the enhanced conductivity of CoPc/GQDs and the biomolecule's interaction with the electrode surface. Furthermore, the proposed sensor shows remarkable reproducibility, repeatability, and stability. The fabricated sensor is applied for the simultaneous detections of DA and UA in human urine samples. The excellent performance suggests that the CoPc/GQDs could be a promising and potential candidate for electrochemical sensors to detect DA and UA selectively.

AbstractLuminogens with aggregation‐induced emission (AIE) properties have received growing interest recently, due to their unique photophysical properties and wide applications. However, the adsorption and fluorescent behaviors of AIE compounds (AIEgens) have been rarely explored on metal surface. Herein, a zwitterionic compound 1 incorporating tetraphenylethylene (TPE) cation and SCN− anion was developed integrating AIE and corrosion inhibition. Weight loss experiment and electrochemical studies manifest 1 is an effective corrosion inhibitor for brass in 0.5 m H2SO4 with inhibition efficiency achieving over 99%. Meanwhile, intensive fluorescence was observed after adsorption of 1 on brass surface, facilitating fluorescent visualization and a new strategy for corrosion inhibition with precise dosing. In contrast, compound 2 with identical TPE cation and SO42− anion has negligible corrosion inhibition effect. The differences of adsorption and fluorescent behaviors between 1 and 2 were attributed to hard and soft acids and bases theory and electrostatic attraction. The corrosion inhibition mechanism was further investigated by comprehensive calculations. This work provides a new approach for visualization of corrosion protection, and enriches understanding of behaviors and functionalities of AIEgens on metal surface.

AbstractDopamine (DA) plays a crucial role in the regulation of human bodily functions and metabolism. It is necessary to detect and then to regulate DA levels for health maintenance. Electrochemical sensors have intrinsic advantages in DA determination, especially for metal nanoparticles‐based sensors with excellent physicochemical properties and efficient activity. In this article, AuNPs located on functional nanographene oxide (NGO) are fabricated for DA detection. As the facial platform, NGO has large surface areas to maintain AuNPs well disperse and provided enough carboxyls and epoxy groups for conjugating with poly(ethylene glycol) (PEG) and thiol active site. Functional biological fluorescence dye (FITC) is also introduced to this NGO platform. With stepwise functionalization, NGO is reconstructed as an optimal foundation for AuNPs presenting the inherent physicochemical properties. Finally, AuNPs are in‐situ grown on the platform by reduction of HAuCl4 under mild conditions, i.e., AuNPs@SH‐NGO‐PEG‐FITC. In the detection of DA levels, AuNPs/NGO nanocomposites are coated on a glassy carbon electrode (GCE). Relying on corresponding cyclic voltammetric curves and typical ready‐state amperometric curves, it is informed that GCE/AuNPs@SH‐NGO‐PEG‐FITC can be employed in the electrochemical detection of DA levels. It is foreseen that efficient sensors and methods for DA determination with fluorescence tracers are provided.

AbstractWith the boom of artificial intelligence (AI) and big data, electronics demand faster computing speed and lower power consumption, however, von Neumann architecture of current devices feature severe drawbacks for the further improvement of computing capability due to its design with separated memory and central processing unit (CPU). Fortunately, emerging nonvolatile memory devices, especially memristors, exhibit tremendous advantages in breaking the “memory wall” between memory and CPU by virtue of their in‐computing and neuromorphic computing abilities. Here, a WO3/HfO2 heterojunction‐based memristor is proposed, and the device exhibits extraordinary resistive switching behaviors (e.g., high ON/OFF ratio, stable endurance, long retention time, and multilevel resistance states) and neuromorphic characteristics (long‐term/short‐term synaptic activities). Further, the mechanism underlying the electrical performances of this device is studied. Silver conductive filaments and Schottky barrier models are proposed and explained successfully. Additionally, a multilayer layer perceptron neural network is constructed in terms of the memristor model, and variables embracing learning rate, algorithm, and training epochs, are explored to enhance the recognition accuracy of the network. Undoubtedly, the proposed high‐quality WO3/HfO2 heterojunction‐based memristor contributes to promoting the development of high‐density storage and neuromorphic computing technology, showing fascinating prospects in the era of AI.

AbstractChanging the chemical composition and generating heterogeneous structures have a synergistic effect on the third‐order nonlinear optical (NLO) properties of metal–organic frameworks (MOFs) materials. In this work, it is demonstrated that the transformations from a parent‐MOF [Zn4(dcpp)2(DMF)3(H2O)2]n (1, dcpp = 3,4‐bis(4‐carboxyphenyl)phthalate) into two child‐MOFs, [Cu4(dcpp)2(DMF)3(H2O)2]n (2) or [Zn2.5Co1.5(dcpp)2(DMF)3(H2O)2]n (3), via central metal exchange can regulate the third‐order NLO properties of the parent‐MOF, especially its third‐order NLO absorption signal can change from the reverse saturable absorption (RSA) to the saturable absorption (SA) when Cu2+ are introduced. Heterogeneous 1@CeO2 materials are further engineered by depositing CeO2 nanospheres onto the whole surface of 1, and are surprisingly still able to be exchanged into 2@CeO2 or 3@CeO2. Analyses on these MOFs@CeO2 indicate that the interfacial interaction between metal oxide particles and MOFs surface can effectively tune the charge transfer efficiency of the material which leads to their third‐order NLO refraction signals. The interface inducement of CeO2‐shell to the MOF‐core also significantly changes their third‐order NLO properties compared to pure MOFs. This work provides new insights and efficient strategies for the development of new third‐order NLO materials with potential practical usage.

Published: October 2022

AbstractMemory device is an important part of electronic equipment. 2D transition metal dichalcogenides that exhibit novel electrical characteristics hold promise in developing new types of memory device. Here, the memory effect in 2D mica/WSe2 heterostructure is investigated. Under applying constant bias voltage and gate voltage, the K+ ions in mica will migrate in the direction of the electric field and be trapped to enable the memory function. The gradient K+ ions work as long‐range scatters to electrostatically dope the WSe2 channel. The shift of the threshold voltage indicates an electrostatic doping concentration up to 2.11 × 1012 cm−2. The operating voltage is as low as 10 V and the on/off ratio is estimated to be 104. To determine the mechanism, the dynamic behavior of the device is discussed and a model is proposed which reveals the correlation between the programming/erasing process and the device performance. Moreover, through defining and studying the effective charge trapping rate, θ, it is found that the trapped charge is proportional to the charge flowing through the channel which means that the device performance can be finely tuned by the programming process.

AbstractNeuromorphic system based on artificial synaptic devices is considered as a potential candidate to realize the in‐memory computing and parallel processing of data for overcoming the von Neumann bottleneck. However, to fully imitate the complicated functions of the biological neural networks at the hardware level is still a challenging task. In this work, a multi‐terminal MoS2 synaptic transistor is developed, which not only simulates various biological synaptic behaviors, including paired pulse facilitation (PPF), excitatory/inhibitory post‐synaptic current (EPSC/IPSC), spike‐rate‐dependent plasticity (SRDP), and spike‐timing‐dependent plasticity (STDP), but also can independently mimic the parallel signal processing and transmissions in biological multipolar neurons. By combining the multi‐terminal MoS2 synaptic transistor with the micro‐structured polydimethylsiloxane (PDMS) pressure sensors, an intelligent tactile recognition system is built up, which can realize the spatiotemporal recognition of touch position. Furthermore, with sensor selection, the spatiotemporal modulation of synaptic plasticity and the human learning and forgetting behaviors to the knowledge with different difficulty degrees can be mimicked. This work provides a novel interconnection scheme for simulating signal transmission and processing among neurons, showing broad application prospects of the multi‐terminal MoS2 synaptic transistor in intelligent human–computer interaction and bionic neuromorphic perception systems.

AbstractThe multilayer triboelectric nanogenerators (TENGs) are widely developed to enhance the output performance of device. However, these TENGs consisting of electron transfer, transport, trap layers toward a large volumetric charge density should be wearable and mass‐produced for commercialization. Thus, appropriate material selection in respective layers and fabrication method are crucial for the commercialization of multilayer TENG. This study presents all‐printed, sustainable wearable TENGs based on electron accumulation polymers (EAPs) with superior charge retention capability. The EAPs consisting of polytetrafluoroethylene (PTFE), carboxyl functionalized single‐walled carbon nanotubes (SWCNTs:COOH), and Ti3C2Tx (MXene) in a fluorinated polymer matrix, are used. Compared to the reference, the EAPs not only lead to approximately six times higher output performance (300 V and 40 µA) but also four times more sustainable charge retention capability (92%) for an hour. These are attributed to the three‐step electron‐trapping mechanism with electron transfer/transport from PTFE/SWCNT and electron trapping in MXene. In addition, TENGs with EAPs exhibit excellent mechanical stability and reliability with fascinating single‐electrode demonstrations. Finally, the TENG with EAPs can efficiently operate various portable electronics and pH monitoring systems with a pH sensor and a seven‐segment display in realistic scenarios.

AbstractFor proton exchange membrane fuel cells to be cost‐competitive in light‐ and heavy‐duty vehicle applications, their Pt content in the catalyst layers needs to be lowered. However, lowering the Pt content results in voltage losses due to high local oxygen transport resistances at the ionomer–Pt interface. It is therefore crucial to use ionomers that have higher oxygen permeability than Nafion. In this work, novel high oxygen permeability ionomers (HOPIs) are presented, with up to five times higher oxygen permeability than Nafion, synthesized by copolymerization of perfluoro‐2,2‐dimethyl‐1,3‐dioxole (PDD) with perfluoro(4‐methyl‐3,6‐dioxaoct‐7‐ene) sulfonyl fluoride (PFSVE). PDD is the source of higher permeability due to its open ring structure, while PFSVE provides ionic conductivity. Optimization of PDD content and equivalent weight enables increased fuel cell performance, mainly at high current densities, where HOPIs can achieve power densities >1.25 W cm−2 and exceed the 0.8 A cm−2 U.S. Department of Energy durability target by losing only 4.5 mV, which is over six times less than 30 mV. The interactions between HOPI and SO3− groups with a PtCo/C catalyst are also elucidated here at a fundamental level.

AbstractThe clinical characteristics of autosomal dominant tubulointerstitial kidney disease (ADTKD) include bland urinary sediment, slowly progressive chronic kidney disease (CKD) with many patients reaching end stage renal disease (ESRD) between age 20 and 70 years, and autosomal dominant inheritance. Due to advances in genetic diagnosis, ADTKD is becoming increasingly recognized as a cause of CKD. Pathogenic variants in UMOD, MUC1, and REN are the most common causes of ADTKD. ADTKD‐UMOD is also associated with hyperuricemia and gout. ADTKD‐REN often presents in childhood with mild hypotension, CKD, hyperkalemia, acidosis, and anemia. ADTKD‐MUC1 patients present only with CKD. This review describes the pathophysiology, genetics, clinical manifestation, and diagnosis for ADTKD, with an emphasis on genetic testing and genetic counseling suggestions for patients.

AbstractA longstanding challenge in fabricating high‐dielectric polymer composite is how to rationalize structure design to improve dielectric constant while minimizing dielectric loss. In this work, we provide a critical material design concept for high‐performance flexible dielectric nanocomposite (PCGA) based on backfilling polydimethylsiloxane (PDMS) matrix into the pre‐constructed chitosan‐reduced graphene oxide (rGO) aerogel with 3D conductive network. Herein, the 3D conductive network enables PCGA to achieve the percolation threshold with a small amount of rGO, which improving the dielectric constant. Simultaneously, the chitosan insulating barrier layer prevents the generation of leakage current between conductive fillers interfaces, which suppressing the losses of the PCGA, thus ensuring the balance between dielectric constant and loss. The results demonstrated that the PCGA (0.06 g rGO) exhibited a dielectric constant as high as 297.3 and a loss tangent as low as 1.91. Subsequently, the as‐obtained PCGA composites as a dielectric interlayer was employed for preparing capacitive sensor. The results demonstrated that the sensor possesses a desirable integration of high sensitivity (5.8% kPa−1 in the pressure range 0–7 kPa) and wide work range (0–140 kPa) due to the synergistic effect of the excellent mechanical performance along with high‐dielectric constant and suppressed loss.
