AbstractThe development of organic electrochemical transistors (OECTs) capable of maintaining their high amplification, fast transient speed, and operational stability in harsh environments will advance the growth of next‐generation wearable and biological electronics. In this study, a high‐performance solid‐state OECT (SSOECT) is successfully demonstrated, showing a recorded high transconductance of 220 ± 59 S cm−1, ultrafast device speed of ≈10 kHz with excellent operational stability over 10 000 switching cycles, and thermally stable under a wide temperature range from −50 to 110 °C. The developed SSOECTs are successfully used to detect low‐amplitude physiological signals, showing a high signal‐to‐noise‐ratio of 32.5 ± 2.1 dB. For the first time, the amplifying power of these SSOECTs is also retained and reliably shown to collect high‐quality electrophysiological signals even under harsh temperatures (−50 and 110 °C). The demonstration of high‐performing SSOECTs and its application in harsh environment are core steps toward their implementation in next‐generation wearable electronics and bioelectronics.

AbstractDeveloping nanomaterials with high H2O2‐decomposition capacity to replace traditional biological enzymes is of great importance in environmental, semiconductor, and medical fields. However, a lack of understanding of the reaction mechanism leads to aimless catalyst design and limits further improvement of catalytic activity. Here, the regulatory mechanism based on the electron filling and orbital energies of the metal active centers is demonstrated and a rational catalyst design strategy is provided to achieve ultrahigh H2O2‐decomposition activity. Among the five platinum‐group‐metal active centers investigated in this study, the Ir–N4 with partially occupied dx2−y2 and dxz orbitals and the highest d‐band center most strongly interacts with H2O2, and show the lowest energy barrier for H2O2 decomposition. As expected, the single‐atom Ir catalyst (Ir‐NC) shows an ultrahigh H2O2‐decomposition capacity, which is 1614‐times higher than that of natural catalase. Surface‐adsorbed atomic oxygen is observed and verified to be the key intermediate for O2 generation. Biocompatible Ir‐NC is effective in scavenging intracellular reactive oxygen species and holds great potential for clinical therapeutics associated with oxidative stress. This study advances the mechanistic understanding of H2O2 decomposition and provides useful guidance for rational design of high‐performance artificial nanozymes.

AbstractTemperature variation‐induced thermoelectric catalytic efficiency of thermoelectric material is simultaneously restricted by its electrical conductivity, Seebeck coefficient, and thermal conductivity. Herein, Bi2Te3 nanosheets are in situ grown on reduced graphene oxides (rGO) to generate an efficient photo‐thermoelectric catalyst (rGO‐Bi2Te3). This system exhibits phonon scattering effect and extra carrier transport channels induced by the formed heterointerface between rGO and Bi2Te3, which improves the power factor value and reduces thermal conductivity, thus enhancing the thermoelectric performance of 2.13 times than single Bi2Te3. The photo‐thermoelectric catalysis of rGO‐Bi2Te3 significantly improves the reactive oxygen species yields, resulting from the effective electron–hole separation caused by the unique thermoelectric field and heterointerfaces of rGO‐Bi2Te3. Correspondingly, the electrospinning membranes containing rGO‐Bi2Te3 nanosheets exhibit high antibacterial efficiency in vivo (99.35 ± 0.29%), accelerated tissue repair ability, and excellent biosafety. This study provides an insight into heterointerface design in photo‐thermoelectric catalysis.

AbstractAbundant intrinsic defects and defect clusters in Cu2ZnSn(S,Se)4 (CZTSSe) solar cells lead to severe nonradiative recombination and limited photoelectric performance. Therefore, developing effective method to suppress the detrimental defects is the key to achieve high‐efficiency solar cell. Herein, a convenient two‐step cooling strategy in selenization process is reported to suppress the CuZn and SnZn defects and defect clusters synergistically. The results show that rapid cooling during section from selenization temperature to turning temperature can inhibit the volatilization of Sn and restrain the corresponding Sn‐related defects, while slow cooling during the subsequent temperature section can reduce the degree of Cu‐Zn disorder. Benefitting from the synergistic effect of two‐step cooling, a significantly lowered concentration of SnZn and CuZn defect and their defect clusters [2CuZn+SnZn] in absorber is observed, meanwhile, a reduced band tailing effect and promoted carrier collection efficiency of the photovoltaic device is obtained. Finally, a device with improved open‐circuit voltage (Voc) of 505.5 mV and efficiency of 12.87% is achieved. This study demonstrates the impact of cooling process on defects controlling for the first time and provides a simple and effective new strategy for intrinsic defect control, which may be universal in other inorganic thin film solar cells.

AbstractImproving the platinum (Pt) mass activity for low‐cost electrochemical hydrogen evolution is an important and arduous task. Here, a selective etching‐reducing fluidized bed reactor technique is reported to create Ti vacancies and firmly anchor single Pt atoms on the active {100} facets of titanium carbide (TiC) to increase the Pt utilization efficiency and improve catalytic activity significantly by a synergistic effect between Ti vacancies and Pt atoms. The generated Ti vacancies are negatively charged and stabilize Pt atoms by forming covalent PtC bonds, showing excellent long‐term durability. Pt single atoms (ultralow load of 1.2 µg cm−2) on the defective TiC {100} show remarkable activity (24.9 mV at 10 mA cm−2) and a mass activity (49.69 A mg−1) ≈190 times that of the state‐of‐the‐art PtC catalyst and nearly double the previously reported best values. The developed cation defect engineering exhibits excellent potential for fabricating next‐generation advanced single‐atom catalysts for large‐scale hydrogen evolution at a low cost.

Published: November 2022

AbstractLithium−sulfur (Li−S) batteries with ultrahigh theoretical energy densities have thus far attracted significant attention as the next‐generation energy storage systems. However, the presence of the polysulfide shuttle effect and sluggish reaction kinetics have critically hindered their research progress. Herein, the fabrication of novel VC‐VO heterogeneous particles supported on a hierarchical porous carbon matrix (VC‐VO/HPC) is reported that regulate the disordered motion of lithium polysulfides (LiPSs); these particles can simultaneously achieve powerful anchoring, fast diffusion, and high‐efficiency conversion of LiPSs. Moreover, the in situ characterization of VC‐VO/HPC@S provides a rational inference for their phase evolution in the galvanostatic charge/discharge process. The formation of the V5S8 phase during electrochemical cycling primarily facilitates the interconversion of liquid‐phase polysulfides. Consequently, the VC‐VO/HPC@S cathodes exhibit excellent capacity performance (1484 mAh g−1 at 0.1 C) and ultrahigh cycle stability (0.045% decay rate per cycle at 5 C). The pouch cell exhibits a high energy density of 358 Wh kg−1. This approach explores the phase evolution of VC‐VO particles in an electrochemical environment and is valuable for the development of Li−S batteries with high area capacity and long cycle life.

Published: November 2022

AbstractSolid‐state batteries (SSBs) are regarded as next generation advanced energy storage technology to provide higher safety and energy density. However, a practical application is plagued by large interfacial resistance, owing to solid‐solid interface contact between ceramics electrolytes and Li anode. Introducing polymer‐based coating between electrolytes and Li anode is a feasible strategy to solve this issue. Unfortunately, current polymer is hard to achieve intimate contact at the atomic scale and lacks of a bridge to transfer Li+ quickly between electrolytes and polymer coating. This gives rise to sluggish Li+ transfer dynamics, huge interface impedance and greatly limits the effectiveness of this strategy. Herein, Poly(lithium 4‐styrenesulfonate)(PLSS) is introduced between Li6.5La3Zr1.5Ta0.5O12 (LLZTO) electrolyte and Li anode. The theories and experiments prove the existence of strong coordinating interaction between SO3Li in PLSS and atoms on LLZTO surface. This interaction structures a bridge to migrate Li+ fast across LLZTO/PLSS interface and hence interface impedance is as low as 9 Ω cm2. Moreover, the electron‐blocking feature of PLSS can prevent electrons from tunneling the LLZTO/PLSS interface and combining with Li+ to form dendrite within LLZTO. PLSS‐base cells show improved long‐life cycling for 4700 h at 0.1 mA cm−2 at room temperature.

AbstractChemoradiotherapy is the standard of care for the clinical treatment of locally advanced head and neck cancers. However, the combination of ion radiation with free chemotherapeutics yields unsatisfactory therapeutic output and severe side effects due to the nonspecific biodistribution of the anticancer drugs. Herein, a self‐cooperative prodrug nanovesicle is reported for highly tumor‐specific chemoradiotherapy. The nanovesicles integrating a prodrug of oxaliplatin (OXA) can passively accumulate at the tumor site and penetrate deep into the tumor mass via matrix metalloproteinase 2‐mediated cleavage of the polyethylene glycol corona. The OXA prodrug can be restored inside the tumor cells with endogenous glutathione to trigger immunogenic cell death (ICD) of the tumor cells and sensitize the tumor to ion radiation. The nanovesicles can be further loaded with the JAK inhibitor ruxolitinib to abolish chemoradiotherapy‐induced programmed death ligand 1 (PD‐L1) upregulation on the surface of the tumor cells, thereby prompting chemoradiotherapy‐induced immunotherapy by blocking the interferon gamma‐Janus kinase‐signal transducer and activator of transcription axis. The prodrug nanoplatform reported herein might present a novel strategy to cooperatively enhance chemoradiotherapy of head and cancer and overcome PD‐L1‐dependent immune evasion.

AbstractDoping of all‐inorganic lead halide perovskites to enhance their photovoltaic performance and stability has been reported to be effective. Up to now most studies have focused on the doping of elements in to the perovskite lattice. However, most of them cannot be doped into the perovskite lattice and the roles of these dopants are still controversial. Herein,the authors introduce CdI2 as an additive into CsPbI3−xBrx and use it as active layer to fabricate high‐performance inorganic perovskite solar cells (PSCs). Cd with a smaller radius than Pb can partially substitute Pb in the perovskite lattice by up to 2 mol%. Meanwhile, the remaining Cd stays on the surface and grain boundaries (GB) of the perovskite film in the form of Cs2CdI4−xBr−x, which is found to reduce non‐radiative recombination. These effects result in prolonged charge carrier lifetime, suppressed defect formation, decreased GBs, and an upward shift of energybands in the Cd‐containing film. A champion efficiency of 20.8% is achieved for Cd‐incorporated PSCs, together with improved device ambient stability. This work highlights the importance of simultaneous lattice engineering, defectcontrol and atomic‐level characterization in achieving high‐performance inorganic PSCs with well‐defined structure‐property relationships.

Published: November 2022

AbstractElectrochemical processes underlie the functioning of electrochemical devices for energy storage and conversion. In this paper, electrochemoinformatics is defined as a scientific discipline, a part of computational electrochemistry, dealing with the application of information technologies, specifically data science, machine learning (ML), and artificial intelligence, to solve problems related to electrochemical processes, including the development of materials and electrochemical devices. Electrochemoinformatics is closely related to chemoinformatics and materials informatics and relies on the technologies they use. The definitions and the basics of chemoinformatics and materials informatics are reviewed with an emphasis on the role of data science, data representation, the use of ML methods, and molecular and material descriptors. The third constituent part of electrochemoinformatics is full‐cell informatics, which deals with the performance and design of whole electrochemical devices. The article focuses on the use of electrochemoinformatics in battery science and technology (battery informatics), including the development of electrolyte and electrode materials, battery performance monitoring, modeling, and design. The scope and the main challenges facing electrochemoinformatics are discussed.
Electrochemical Performance Enhancement of 3D Printed Electrodes Tailored for Enhanced Gas Evacuation during Alkaline Water Electrolysis

Published: November 2022

AbstractA zero‐gap cell with porous electrodes is a promising configuration for alkaline water electrolysis. However, gas evacuation becomes a challenge in that case, as bubbles can get trapped within the electrode's 3D structure. This work considers a number of 3D printed electrode geometries with so‐called triply periodic minimal surfaces (TPMS). The latter is a mathematically defined structure that repeats itself in three dimensions with zero mean curvature, and can therefore be expected to be particularly well‐suited to enhance gas evacuation. Another advantage as compared to other state‐of‐the‐art 3D electrodes like foams or felts lies in the fact that their porosity, which determines the available surface area, and their pore size or flow channel dimensions, which determines the degree of bubble entrapment, can be varied independently. By a combined experimental and modeling approach, this work then identifies the structural parameters that direct the performance of such 3D printed TPMS geometries toward enhanced gas evacuation. It is demonstrated that an optimal combination of these parameters allows, under a forced electrolyte flow, for a reduction in cell overpotential of more than 20%. This indicates that efforts in optimizing the electrode's geometry can give a similar electrochemical performance enhancement as optimizing its electro‐catalytic composition.

AbstractControlling the lithium growth morphology in lithium reservoir‐free cells (RFCs), so‐called “anode‐free” solid‐state batteries, is of key interest to ensure stable battery operation. Despite several benefits of RFCs like improved energy density and easier fabrication, issues during the charging of the cell hinder the transition from lithium metal batteries with a lithium reservoir layer to RFCs. In RFCs, the lithium metal anode is plated during the first charging step at the interface between a metal current collector and the solid electrolyte, which is prone to highly heterogeneous growth instead of the desired homogeneous film‐like growth. Herein, the lithium morphology during the first charging step in RFCs is explored as a function of current density and current collector thickness. Using operando scanning electron microscopy, an increase in the lithium particle density is observed with increasing current density at the Cu|Li6.25Al0.25La3Zr2O12 interface. This observation is then applied to improve the area coverage of lithium by pulsed plating. It is also shown that thin current collectors (d = 100 nm) are unsuited for RFCs, as lithium whiskers penetrate them, resulting in highly heterogeneous interfaces. This suggests the use of thicker metal layers (several µm) to mitigate whisker penetration and facilitate homogeneous lithium plating.

AbstractObjectivesWhile adverse childhood experiences (ACEs) have been shown to be associated with adulthood obesity, less is known about their association with underweight. We examined the associations between parental absence (i.e., a major component of ACEs) and both underweight and excess weight among middle‐aged rural community dwellers in Vietnam, where experiences of parental absence was not uncommon during and after the Vietnam War (1955–1975).MethodsData came from 3000 middle‐aged adults who participated in the baseline survey of Khánh Hòa Cardiovascular Study. Parental absence was defined as parental absence due to death, divorce, or out‐migration. Using information on the timing of such events, we categorized participants into those who experienced parental absence before the age of 3, between the ages of 3 and 15, and those without such experiences. BMI was calculated based on measured height and weight (kg/m2) and categorized into three groups: underweight <18.5; normal 18.5–24.9; excess weight ≥ 25. Multinomial logistic regression was then used to investigate the association between parental absence and adult weight status.ResultsParental absence that occurred before the age of 3 was marginally significantly associated with underweight (relative risk ratio [RRR] = 1.44, 95% confidence interval [CI] 0.95, 2.20) but not with overweight/obesity. Parental divorce was associated with overweight/obesity (RRR = 2.48, 95% CI 1.28, 4.81), but not parental absence due to migratory work.ConclusionsWhile previous studies in Western settings focused almost exclusively on the risk of obesity in relation to exposure to ACEs, our findings point to the potential importance of considering the risk of underweight in low‐ and middle‐income countries.
