Published: September 2023

AbstractTriboelectric nanogenerators (TENGs) are considered one of the most effective methods for harvesting irregular and low‐frequency raindrop energy. In this work, molybdenum selenide (MoSe2) nanosheets act as intermediate layers for improving droplet‐based TENG performance. Consequently, without surface etching process, the short‐circuit current (Isc) and open‐circuit voltage (Voc) of the TENG can reach as high as 1.2 mA and 120 V, respectively. Furthermore, precise energy analysis based on an optimization model for input energy calculation is carried out, allowing conversion efficiency to be calculated under diverse conditions. Finally, an all‐solid supercapacitor is fabricated for integration with the TENG. An intelligent wireless sensing system, powered by the integrated TENG and capacitor, is demonstrated for monitoring environmental information. This study provides new insights into intermediate‐layer materials' selection and action mechanisms. It fills a gap in the research on a precise model of theoretical energy conversion efficiency calculation. The integrated devices and sensing applications will provide strategies for creating smart cities.

AbstractElectrochemical reduction of CO2 toward value‐added liquid fuel is a promising route to achieve the carbon neutrality. Especially for CO2 electroreduction to formic acid production, despite the favorable activity and selectivity can be achieved, unstable Faradaic efficiency (FE) in wide potential range and poor energy efficiency remain the bottlenecks. Herein, this study reports a metallic Bi catalyst (B‐ArH2‐2) derived from defective Bi2O3, which achieves nearly 100% FE for HCOOH production over a broad potential range (−0.7 to −1.1 V) with an outstanding cathodic energy efficiency of 71%. Additionally, B‐ArH2‐2 displays a high partial current density of HCOOH (jHCOOH, 27.5 mA cm−2) and production rate (475 µmol h−1 cm−2) with favorable long‐term stability (20 h).

AbstractSolid‐state batteries (SSBs) have received significant attention due to their high energy density, reversible cycle life, and safe operations relative to commercial Li‐ion batteries using flammable liquid electrolytes. This review presents the fundamentals, structures, thermodynamics, chemistries, and electrochemical kinetics of desirable solid electrolyte interphase (SEI) required to meet the practical requirements of reversible anodes. Theoretical and experimental insights for metal nucleation, deposition, and stripping for the reversible cycling of metal anodes are provided. Ion transport mechanisms and state‐of‐the‐art solid‐state electrolytes (SEs) are discussed for realizing high‐performance cells. The interface challenges and strategies are also concerned with the integration of SEs, anodes, and cathodes for large‐scale SSBs in terms of physical/chemical contacts, space‐charge layer, interdiffusion, lattice‐mismatch, dendritic growth, chemical reactivity of SEI, current collectors, and thermal instability. The recent innovations for anode interface chemistries developed by SEs are highlighted with monovalent (lithium (Li+), sodium (Na+), potassium (K+)) and multivalent (magnesium (Mg2+), zinc (Zn2+), aluminum (Al3+), calcium (Ca2+)) cation carriers (i.e., lithium‐metal, lithium‐sulfur, sodium‐metal, potassium‐ion, magnesium‐ion, zinc‐metal, aluminum‐ion, and calcium‐ion batteries) compared to those of liquid counterparts.

AbstractHydride ion conductors have made remarkable progress in recent years; in particular, the fluorite‐type LaH3‐δ series exhibits high conductivity around room temperature. However, its intrinsic character of hydrogen non‐stoichiometry still makes its application as a solid electrolyte challenging, for which high electronic insulation is essential. Here, Sr‐substituted LaH3‐δ with slight O2− incorporation, represented as La1‐xSrxH3‐x‐2yOy (0.1 ≤ x ≤ 0.6, y ≤ 0.171), is synthesized, which exhibits H− conductivity of 10−4 – 10−5 S cm−1 at room temperature. The galvanostatic discharge reaction using an all‐solid‐state cell composed of Ti|La1‐xSrxH3‐x‐2yOy|LaH3‐δ shows that the Ti electrode is completely hydrogenated to TiH2 for x ≥ 0.2, whereas a short circuit occurs for x = 0.1. These experimental observations, together with calculation studies on the density of states and the defect formation energy, provide clear evidence that electropositive cation, such as Sr, doping critically suppresses the electron conduction in LaH3‐δ. Achieving a superior H− conducting solid electrolyte is a novel milestone in the development of electrochemical devices that utilize its strong reducing ability (E°(H−/H2) = −2.25 V vs SHE), such as batteries with high energy density and electrolysis/fuel cells with high efficiency.

AbstractThe silicon anode is promising for high‐energy density lithium‐ion batteries owing to its ultrahigh theoretical capacity. However, the practical deployment of Si anodes is significantly hindered by its large volume change and unstable electrode/electrolyte interphase associated with routine electrolytes. Herein, a cyclic ether‐based electrolyte is designed and shows high compatibility with Si anodes. By simply decreasing the prevalence of ethereal oxygen groups and increasing the degree of molecule unsaturation of 1,2‐dimethoxyethane simultaneously, the resulting cyclic tetrahydrofuran (THF) presents a weak solvation capability and strong polymerization. Experimental and computational evidence demonstrates this rational design leads to a remarkable improvement in electrochemical performance of Si anodes. By forming a thin, elastic, and LiF‐rich inorganic‐polymeric solid‐electrolyte interphase film, the Si electrode cycled in THF‐based electrolyte exhibits long‐term cycling stability with a high reversible capacity of 1995.7 mAh g−1 after 400 cycles. The full‐cells with Si/graphite anodes and LiFePO4 cathodes maintain over 80% capacity retention after 600 cycles.

AbstractAqueous zinc‐based batteries are a promising alternative to lithium batteries. These batteries, however, persistently suffer from uncontrollable dendrite growth and sustained water consumption at the Zn anodes, along with low and often fading capacity at the cathodes. Herein, Zn metal is simply encapsulated into a chitosan‐containing polymer gel that not only suppresses hydrogen evolution but also enables dendrite‐free Zn plating/stripping. A binder‐free cathode based on the electrochemically exfoliated and partially sulfidated Ni–Co–Fe layered double hydroxide‐reduced graphene oxide (SNS‐rGO) nanocomposite is also reported. The fabricated devices (based on either Zn or chitosan‐coated Zn) deliver near record‐high values of specific capacity (756 mA h g−1cathode at 1 A g−1) and specific energy (1284 W h kg−1cathode), along with an outstanding specific power (108 kW kg−1cathode), an excellent output voltage (up to 1.9 V), and prolonged cycling stability at 100% depth‐of‐discharge. This interface engineering strategy, supported by the density functional theory calculations, provides a solid basis for further practical applications of aqueous Zn batteries.

AbstractSolid oxide cells (SOCs) are pivotal in electrochemical energy conversion technologies, but their operation at high temperatures necessitates the development of efficient and durable electro‐catalysts. Herein, a novel electro‐catalyst composed of Pt3Ni alloy nanoparticles exsolved on oxygen‐deficient PrBaMn1.8Pt0.15Ni0.05O5+δ layered perovskite oxides is presented. This design addresses the critical problem of nanoparticle agglomeration at high temperatures, a major hurdle for SOCs. The atomic‐scale mechanisms of oxygen vacancy formation and hydrogen evolution reaction kinetics in the material are unraveled through density functional theory calculations. A unique finding of this work is the formation of a core‐shell structure during water electrolysis, simultaneously enhancing the electrochemical performance and operational durability in both fuel cell and electrolysis cell modes. This study not only strengthens the potential of Pt‐Ni alloy nanoparticles as efficient electro‐catalysts for SOCs, but also opens up avenues for future exploration in energy‐related fields.

AbstractSodium‐based layered oxide cathodes are competitive candidates for commercial sodium‐ion batteries owing to their high theoretical capacities, low costs, and simple synthesis. P3‐type layered oxides with large open channels enable fast Na+ transport and hence good rate performance. However, the lower crystal symmetry of P3‐type oxides and variation of Na+ contents in the Na layer during desodiation/sodiation lead to large electrostatic repulsion changes between TMO2 slabs (TM=Transition Metal), resulting in irreversible phase transitions, and fast performance degradation. Herein, a potential Na+ conductor Na2SeO4 is first found that it can be easily in situ grown on P3‐Na0.45Ni0.2Mn0.8O2 to form a novel heterostructure P3‐Na0.45Ni0.2Mn0.8O2/Na2SeO4. The synergy between P3‐Na0.45Ni0.2Mn0.8O2 and Na2SeO4 functions in promoting Na+ diffusion and suppressing P3‐O3 phase transitions upon deep sodiation, which results in recorded high‐rate capability (68.2% capacity retention with retained 83.9 mAh g−1 capacity at 6400 mA g−1) and superior cycling stability (capacity retention 75% after 1000 cycles) among all reported P3‐type cathodes. Thus, it is believed that this novel heterostructure design opens a new pathway to promote practical applications for layered oxide cathodes in sodium‐ion batteries.

AbstractMultivalent ion batteries (e.g., Zn2+, Ca2+) are gaining great attention owing to their potentially high capacity, cheap cost, and good safety. However, significant disparities exist in achieved capacity, voltage, and kinetic performance within zinc and calcium ion electrolytes. Herein, the electrochemical and kinetic properties of Zn2+ and Ca2+ in aqueous electrolytes are investigated using a single‐crystal V2O5 (V2O5·Pyridine, PVO) model material with stable large interlayer spacing. It is found that the discharge‐specific capacity in 1 m Zn(ClO4)2 aqueous solution is 247.3 mAh g−1 at 0.3 A g−1, which is remarkably higher than 158.4 mAh g−1 in 1 m Ca(ClO4)2. Mechanistic studies show that in aqueous ZIB, H+ is intercalated first, followed by the generation of Zn4(OH)7ClO4, and finally H+ and Zn2+ are co‐intercalated. But in aqueous CIB, H+ dominates the intercalation process. It is found that six times more Zn2+ than Ca2+ is intercalated into PVO, owing to its smaller radii and its relative higher intercalation potential (Zn2+ @‐0.34 V, Ca2+ @‐0.65 V vs.. Ag/AgCl), giving it a higher specific capacity. Furthermore, density functional theory calculations demonstrate lower intercalation energies for Ca2+ (−6.67 eV) compared to Zn2+ (−1.85 eV), explaining the lower intercalation potential of Ca2+.

AbstractObjectivesComposite Index of Anthropometric Failure (CIAF) and Extended CIAF (ECIAF) allow for the identification of simultaneous presence of two or more types of malnutrition. The objective of this study was to analyze anthropometric failure in Argentinean children under 5 years old, taking into consideration regional and socioeconomic perspectives.Materials and MethodsData from the National Survey of Children and Adolescents MICS 2019–2020 were used, which included 5473 children under 5 years old of both sexes residing in the six regions of Argentina. CIAF and ECIAF excludes children not in anthropometric failure (group A) and was calculated from a percentage of children included in malnutrition categories B: wasting only; C: wasting and underweight; D: wasting, stunting, and underweight; E: stunting and underweight; F: stunting only; Y: underweight only; G: only weight excess; and H: stunting and weight excess. The data were analyzed according to region and wealth quintile.ResultsIn children aged 0–2.99 years, CIAF was 12.5% and ECIAF was 27.7%, with boys being more affected. In children aged 3–4.99 years, the rates were 9.7% and 22.3%, respectively, with girls showing a higher prevalence. The highest ECIAF was recorded in the Patagonia region (31.3%), while the highest ECIAF was observed in the poorest quintile.DiscussionThe presence of double burden of malnutrition has been observed across all regions and household income levels. Additionally, overweight has shown a higher intensity in economically prosperous regions and households, while stunting has been more prevalent in economically disadvantaged areas.

AbstractThe collection of known genetic etiologies of neurodevelopmental disorders continues to increase, including several syndromes associated with defects in zinc finger protein transcription factors (ZNFs) that vary in clinical severity from mild learning disabilities and developmental delay to refractory seizures and severe autism spectrum disorder. Here we describe a new neurodevelopmental disorder associated with variants in ZBTB47 (also known as ZNF651), which encodes zinc finger and BTB domain‐containing protein 47. Exome sequencing (ES) was performed for five unrelated patients with neurodevelopmental disorders. All five patients are heterozygous for a de novo missense variant in ZBTB47, with p.(Glu680Gly) (c.2039A>G) detected in one patient and p.(Glu477Lys) (c.1429G>A) identified in the other four patients. Both variants impact conserved amino acid residues. Bioinformatic analysis of each variant is consistent with pathogenicity. We present five unrelated patients with de novo missense variants in ZBTB47 and a phenotype characterized by developmental delay with intellectual disability, seizures, hypotonia, gait abnormalities, and variable movement abnormalities. We propose that these variants in ZBTB47 are the basis of a new neurodevelopmental disorder.

AbstractSelf‐assembled monolayers (SAMs) of N‐heterocyclic olefins (NHOs) have been prepared on Au(111) and their thermal stability, adsorption geometry, and molecular order were characterized by X‐ray photoelectron spectroscopy, polarized X‐ray absorption spectroscopy, scanning tunneling microscopy (STM), and density functional theory (DFT) calculations. The strong σ‐bond character of NHO anchoring to Au induced high geometrical flexibility that enabled a flat‐lying adsorption geometry via coordination to a gold adatom. The flat‐lying adsorption geometry was utilized to further increase the surface interaction of the NHO monolayer by backbone functionalization with methyl groups that induced high thermal stability and a large impact on work‐function values, which outperformed that of N‐heterocyclic carbenes. STM measurements, supported by DFT modeling, identified that the NHOs were self‐assembled in dimers, trimers, and tetramers constructed of two, three, and four complexes of NHO−Au‐adatom. This self‐assembly pattern was correlated to strong NHO−Au interactions and steric hindrance between adsorbates, demonstrating the crucial influence of the carbon‐metal σ‐bond on monolayer properties.

AbstractIn aqueous electrolytes, the uncontrollable interfacial evolution caused by a series of factors such as pH variation and unregulated Zn2+ diffusion would usually result in the rapid failure of metallic Zn anode. Considering the high correlation among various triggers that induce the anode deterioration, a synergistic modulation strategy based on electrolyte modification is developed. Benefitting from the unique pH buffer mechanism of the electrolyte additive and its capability to in situ construct a zincophilic solid interface, this synergistic effect can comprehensively manage the thermodynamic and kinetic properties of Zn anode by inhibiting the pH variation and parasitic side reactions, accelerating de‐solvation of hydrated Zn2+, and regulating the diffusion behavior of Zn2+ to realize uniform Zn deposition. Thus, the modified Zn anode can achieve an impressive lifespan at ultra‐high current density and areal capacity, operating stably for 609 and 209 hours at 20 mA cm−2, 20 mAh cm−2 and 40 mA cm−2, 20 mAh cm−2, respectively. Based on this exceptional performance, high loading Zn||NH4V4O10 batteries can achieve excellent cycle stability and rate performance. Compared with those previously reported single pH buffer strategies, the synergistic modulation concept is expected to provide a new approach for highly stable Zn anode in aqueous zinc‐ion batteries.

AbstractCrystalline triazine‐based covalent organic frameworks (COFs) are aromatic nitrogen‐rich porous materials. COFs typically show high thermal/chemical stability, and are promising for energy applications, but often require harsh synthesis conditions and suffer from low crystallinity. In this work, we propose an environmentally friendly route for the synthesis of crystalline COFs from CO2 molecules as a precursor. The mass ratio of CO2 conversion into COFs formula unit reaches 46.3 %. The synthesis consists of two steps; preparation of 1,4‐piperazinedicarboxaldehyde from CO2 and piperazine, and condensation of the dicarboxaldehyde and melamine to construct the framework. The CO2‐derived COF has a 3‐fold interpenetrated structure of 2D layers determined by powder X‐ray diffraction, high‐resolution transmission electron microscopy, and select‐area electron diffraction. The structure shows a high Brunauer–Emmett–Teller surface area of 945 m2 g−1 and high stability against strong acid (6 M HCl), base (6 M NaOH), and boiling water over 24 hours. Post‐modification of the framework with oxone has been demonstrated to modulate hydrophilicity, and it exhibits proton conductivity of 2.5×10−2 S cm−1 at 85 °C, 95 % of relative humidity.

AbstractUnderstanding the sorption equilibrium of penetrants into a polymer is key to mastering the kinetics and properties of the final product. These systems are non‐ideal meaning the presence of multiple components in the continuous phase changes the solubility of individual species with respect to pure component solubilities. For this reason, measurements of the individual and total solubilities of multiple penetrants in isotactic polypropylene (iPP) and random copolymers (RCP) were performed using a pressure decay method at temperatures of 75–85°C, and total pressures of up to 29 barG. The results showed that the pure component solubilities of propylene and propane in amorphous iPP were similar, but 4 to 5 times higher than that of ethylene in the same polymer. However, in the ternary system of propylene/propane/iPP, it is seen that propylene acts as an anti‐solvent to propane, and that propane acts as an anti‐solvent to propylene, resulting in lower solubility of both penetrants than in the respective binary cases. The co‐solubility effect of propylene on ethylene and the anti‐solvent effect of ethylene on propylene were observed for the system of propylene/ethylene/RCP.
