Corrosion behavior of modified cement-based coated steel rebar subjected to different levels of tensile loads

Polymer-modified cement-based coating can provide corrosion protection for steel rebar. However, after the action of the tensile load, the connection between the polymer and the cement matrix was weakened, thus reducing its corrosion resistance. In this study, silica fume, nano-SiO2, and corrosion inhibitor were used to modify EVA (Ethylene Vinyl Acetate Copolymer) and cement-based coatings. Electrochemical experiments were used to evaluate the corrosion behavior of coated steel rebar after the action of different levels of tensile loads, and microscopic characterization and porosity experiments were applied to analyze the changes of microscopic properties of the coatings. The experimental results show that silica fume and nano-SiO2 produce more high-strength C–S–H gels through hydration reaction to improve the tensile properties and compactness of the coating, thus reducing the porosity and chloride ion permeability of the coating after tension. Tetrabasic-modified cement-based coated steel rebar with EVA, silica fume, nano-SiO2, and amino-alcohol corrosion inhibitor displayed the highest coating resistance and the lowest corrosion current density under the action of tensile load. Experimental results proves that nano-SiO2 enhances the tensile properties of the coating. The addition of corrosion inhibitor can further improve the compactness of the coating under tension, hinder the formation of chloride ion transport channel, and adsorb on the surface of steel rebar to improve the corrosion resistance of steel rebar.

Regulating the Ion Transport in the Layered V2O5 Electrochromic Films with Tunable Interlayer Spacing

AbstractUnveiling the ion transport mechanism to design and explore efficient and stable ion transport pathways for high‐performance transition metal oxide (TMO)−based electrochromic materials is highly desired yet challenging. Herein, this study has demonstrated that the interlayer spacing of layered vanadium penoxide (V2O5) films can be tuned by inserting different amounts of lithium−ion (Li+) within host V2O5 material, as well as adjusting ion transport behavior and electrochromic performance. These results show that V2O5 with a small amount of ion insertion delivers a stable ion transport process and electrochromic properties. Increasing the amount of inserted Li+ will enlarge the interlayer spacing, which provides abundant active sites and efficient ion transport channels, and thus reversible and rich color variation of yellow−green−blue−olive green−orange is realized. Nevertheless, an excess of ion insertion results in the crystal structure collapse and cyclic stability degradation. These findings give a rationale for the evolution of electrochromic properties during different electrochemical reaction stages. This work provides considerable insight into the ion transport behavior within the layered V2O5 films, which gives fundamental theoretical guidance for developing and designing superior layered TMO electrochromic materials.

Porous Structure‐Electrochemical Performance Relationship of Carbonaceous Electrode‐Based Zinc Ion Capacitors

AbstractThe porous structure is critical for carbonaceous electrode‐based zinc‐ion capacitors (ZICs) to achieve excellent electrochemical performance, but the corresponding porous structure‐electrochemical performance relationship is yet to be fully understand. Herein, three types of N‐doped carbons with different porous structures are developed to investigate the relationship between the pore size distribution and the electrochemical performance of the devices. The optimized porous carbon (LVCR) exhibits large electrochemical surface area, plentiful oxygen functional groups, and hierarchical porous structure that facilitates electron transfer and ion diffusion. Consequently, the LVCR‐based ZIC exhibits a remarkable peak power density of 31.4 kW kg−1 and an impressive specific energy density of 126.6 Wh kg−1. Moreover, it demonstrates exceptional longevity, retaining the capacitance of 97.7% even after undergoing 50 000 cycles. Systematic characterization demonstrates that the macroporous and mesoporous structures determine the different stages of Zn2+ storage kinetics. The excellent Zn2+ storage and electrochemical performance of LVCR are attributed to the fast ion transport channels provided by the hierarchical porous structure and facilitated reversible chemisorption and desorption. This work not only deepens the understanding of charge storage mechanism, but also provides guidelines for rationally designing carbonaceous materials toward high‐performance ZICs in the view of porous structure‐electrochemical performance relationship.

Tuning the water interlayer spacer of microwave-synthesized holey graphene films towards high performance supercapacitor application

Abstract Graphene-based electrodes have been extensively investigated for supercapacitor applications. However, their ion diffusion efficiency is often hindered by the graphene restacking phenomenon. Even though holey graphene (hG) is fabricated to address this issue by providing ion transport channels, those channels could still be blocked by densely stacked graphene nanosheets. To tackle this challenge, this research aims at improving the ion diffusion efficiency of microwave-synthesized hG films by tuning the water interlayer spacer towards the improved supercapacitor performance. By controlling the vacuum filtration during graphene-based electrode fabrication, we obtain dry films with dense packing and wet films with sparse packing. The SEM images reveal that 20 times larger interlayer distance is constructed in the wet film compared to that in the dry counterpart. The hG wet film delivers a specific capacitance of 239 F g−1, ∼82% enhancement over the dry film (131 F g−1). By an integrated experimental and computational study, we quantitatively show that the interlayer spacing in combination with the nanoholes in the basal plane dominates the ion diffusion rate in hG-based electrodes. Our study concludes that novel hierarchical structures should be further considered even in hG thin films to fully exploit the superior advantages of graphene-based supercapacitors.

Synergy of structural engineering and VO2 self-transformation enables ultra-high areal capacity cathodes for zinc-ion batteries

The development of cathodes with high areal capacities is a prerequisite for realizing the practical application of zinc-ion batteries (ZIBs). However, the slow ion (de)intercalation kinetics and the highly tortuous ion transport channels in the traditionally blade-coated electrodes limit the practical areal capacities of the ZIB cathodes below 3 mAh cm−2. In this work, multi-stage pore structures, including through-holes perpendicular to the electrode and submicron-scale channels along the radial direction of the printed filaments, are obtained through polyvinylidene difluoride (PVDF) phase separation assisted 3D printing procedure. In this novel electrode material, the porous network enables fast electron/ion transport and improves the accessibility of active materials for thick electrodes with high active material loadings. More importantly, a phase self-transformation of VO2 to a high oxidation state of V5O12∙6H2O is achieved by regulating the charging voltage, which significantly enhances the zinc storage capacity and provides smoother channels for fast ion (de)intercalation. With these unique features, the 3D printed VO2 cathode with a mass loading of 8.9 mg cm−2 demonstrates a high specific capacity of 478.1 mAh g−1 at 1 A g−1 and a stable life cycle for 1000 cycles at 4 A g−1. When the mass loading is increased to 29.6 mg cm−2, the electrode is still able to deliver an ultra-high areal capacity of 16.8 mAh cm−2. The strategies adopted in this work greatly boost up the performance of VO2 cathodes, especially the high areal capacity, by combining structural engineering and material activity regulation.

Ion‐Conducting Molecular‐Grafted Sustainable Cellulose Quasi‐Solid Composite Electrolyte for High Stability Solid‐State Lithium‐Metal Batteries

AbstractCellulose‐based solid electrolyte possesses the characteristics of low cost, high strength, and sustainability, and has great potential in the field of solid‐state lithium metal batteries. However, the large hydrogen bonds between cellulose molecules make the molecular chains tightly arranged, and hinder the ion conduction, seriously limiting its further development. Herein, an ion‐conducting molecular grafting strategy is proposed for the fabrication of cellulose acetate quasi‐solid composite electrolyte (CLA‐CN‐LATP QCE) with a superior ionic conductivity of 1.25 × 10−3 S cm−1 at room temperature. Benefited from grafted functional molecules, the assembled symmetrical battery exhibits low polarization voltage and highly stable lithium stripping/plating cycling of more than 1200 h at 0.1 mA cm−2 current density. Moreover, it endows LFP|CLA‐CN‐LATP QCE|Li battery with excellent long‐cycle stability of 1500 cycles at 0.5 C and 25 °C and superior capacity retention of 92.1%. Importantly, this work provides an effective strategy for further opening the ion transport channel between cellulose molecular chains and improving the interface properties of electrolytes and electrodes.

The role of CBL-CIPK signaling in plant responses to biotic and abiotic stresses.

Plants have a variety of regulatory mechanisms to perceive, transduce, and respond to biotic and abiotic stress. One such mechanism is the calcium-sensing CBL-CIPK system responsible for the sensing of specific stressors, such as drought or pathogens. CBLs perceive and bind Calcium (Ca2+) in response to stress and then interact with CIPKs to form an activated complex. This leads to the phosphorylation of downstream targets, including transporters and ion channels, and modulates transcription factor levels and the consequent levels of stress-associated genes. This review describes the mechanisms underlying the response of the CBL-CIPK pathway to biotic and abiotic stresses, including regulating ion transport channels, coordinating plant hormone signal transduction, and pathways related to ROS signaling. Investigation of the function of the CBL-CIPK pathway is important for understanding plant stress tolerance and provides a promising avenue for molecular breeding.

Ionic liquid reinforced NaSICON-type oxide electrolyte films enabling solid state conversion metal fluoride-lithium batteries

Solid-state batteries (SSBs) with metal fluoride cathodes are an exciting combination due to their high theoretical energy density and good safety. However, owing to the high chemical compatibility requirements between metal fluoride cathode and the solid-state electrolyte (SSE), developing an adaptable SSE film with comprehensive properties is particularly challenging. Herein, a class of ionic liquid (IL) reinforced oxide SSE films was proposed. Among them, the combination of Li1.5Al0.5Ge1.5(PO4)3 (LAGP) oxide SSE and EMIM-based IL (LAGP-EMIM) exhibits good flame-retardant properties, exceptional air stability, high ionic conductivity and excellent chemical stability. The introduction of ILs can increase the ion transport channels in SSEs and render the usage of dry-process, well addressing the contradiction between the flexibility and ionic conductivity of oxide films. The thickness of LAGP-EMIM films is 59 μm and they show the highest ionic conductivity of 1.05 mS cm−1 among the NaSICON-type oxide-based SSE films till now. In addition, it can be stably matched with the conversion metal fluoride cathodes such as FeF3 and CuF2 to construct semi-solid-state batteries, delivering high initial discharge capacity of 820.2 and 539.6 mAh g−1, respectively. The present work shed new insight into designing the composite electrolytes toward the next-generation solid state conversion batteries.

Progress Of Low-Temperature Carbonization of Cellulose as Anode Material for Sodium-Ion Batteries

With the increasingly serious environmental issues brought by the use of conventional fossil energy sources, and under the idea of "carbon peak and carbon neutral" put forward by China, it has been a global consensus to drive the transition of the energy consumption framework from conventional fossil energy sources to low-carbon, clean reproducible energy sources, and associated energy preservation technologies. So far, secondary battery systems as stable and efficient clean energy storage have been the focus of attention, and the most important energy storage devices are lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), which are also potential battery systems under recent research. Nevertheless, the scarcity and grossly uneven allocation of lithium resources as well as the security problems of lithium batteries have limited the further growth of LIBs. Due to these problems, the scientific community has been back to sodium-ion battery studies. By comparing with lithium-ion batteries, sodium resources for sodium-ion batteries are cheaper, richer, and safer, so the social demand for sodium-ion batteries continues to increase, but the larger the ionic radius of sodium ions, the poorer the reversible capacity, the shorter the life span and other problems still exist, and the development of high-performance anode materials is an effective method to solve the core problems of sodium-ion batteries, cellulose-based hard carbon materials have a green preparation process, favorable ion Cellulose-based hard carbon material is a potential anode material for sodium-ion batteries with the green preparation process, beneficial ion transport channel and special porous framework.

A Self-Healing Polymer Binder of Silicon-Based Anode with Enhanced Lithium-Ion Transport Performance

A multi-functional binder was designed for silicon-based anode lithium-ion battery to alleviate the huge volume expansion of silicon anode during the process of charging and discharging, and to provide ion transport channels to improve the rate performance of electrodes to meet the needs of rapid charging and discharging. In this study, a binder PAA-TUEG which combined the mechanical properties of PAA, the fast self-healing ability provided by the zigzag hydrogen bond in TUEG, and the ion transport ability provided by the ether-oxygen group was synthesized. The effect of different proportion of TUEG binder on the electrochemical performance of the electrode was further investigated. The synthesized PAA-TUEG5% polymer material exhibits a tensilestrength of 0.8 MPa and a fracture elongation of 397%. The Si@PAA-TUEG5% electrode demonstrates reversible capacities of 3035, 2260, and 1249 mAh g−1 at 0.5, 1, and 2 C (1 C = 3500 mAh g−1), respectively. In extended cycling tests, the remaining capacities after 180 cycles at 0.5 and 1 C are 852 and 793 mAh g−1, respectively. This innovative binder, featuring both self-healing ability and enhanced ion transport through dynamic reversible hydrogen bond and ionic bond, presents a promising design concept for the next generation of high-energy-density lithium-ion batteries.

Theoretical simulation of ion transport in main-chain poly(arylene piperidinium) anion exchange membranes with crown ether groups

ABSTRACT Experimental studies have confirmed that introduction of the proper content of dibenzo-18-crown-6-ether (DE) into main-chain poly(arylene piperidinium) anion exchange membranes (AEMs) improved the efficiency of OH− transport. In this study, models of the AEMs (PDTP-x) were constructed with varying molar contents of DE groups (x = 0, 0.05, 0.10, 0.15, 0.20 and 0.25). Molecular dynamics simulations were employed to investigate the microscopic effects of the DE groups on OH− transport. The analysis examined the impact of the volume of the overlapping hydration shells around piperidinium groups and the continuities and uniformities of the ion transport channels. Furthermore, the stabilities of the hydrogen bonds between water molecules explained the effect of x on OH− transport. The results showed that the total overlap volume initially increased and then decreased as x increased. When the content of DE groups was appropriate, the hydration shells of the cations exhibited considerable overlap, which facilitated the formation of continuous and uniform ion transport channels. Additionally, the stabilities of the water hydrogen bonds initially decreased and then increased as x increased. The stabilities of the hydrogen bonds were lowest when the DE content was optimal, which facilitated the transport of OH−.

Constructing a 3D Ion Transport Channel-Based CNF Composite Film with an Intercalated Structure for Superior Performance Flexible Supercapacitors.

The weak stiffness, huge thickness, and low specific capacitance of commonly utilized flexible supercapacitors hinder their great electrochemical performance. Learning from a biomimetic interface strategy, we design flexible film electrodes based on functional intercalated structures with excellent electrochemical properties and mechanical flexibility. A composite film with high strength and flexibility is created using graphene (reduced graphene oxide (rGO)) as the plane layer, layered double metal hydroxide (LDH) as the support layer, and cellulose nanofiber (CNF) as the connection agent and flexible agent. The interlayer height can be adjusted by the ion concentration. The highly interconnected network enables excellent electron and ion transport channels, facilitating rapid ion diffusion and redox reactions. Moreover, the high flexibility and mechanical properties of the film achieve multiple folding and bending. The CNF-rGO-NiCoLDH film electrode exhibits high capacitance performance (3620.5 mF cm-2 at 2 mA cm-2), excellent mechanical properties, and high flexibility. Notably, flexible all-solid assembled CNF-rGO-NiCoLDH//rGO has an extremely high area energy density of 53.5 mWh cm-2 at a power density of 1071.2 mW cm-2, along with cycling stability of 89.8% retention after 10 000 charge-discharge cycles. This work provides a perspective for designing high-performance energy storage materials for flexible electronics and wearable devices.

In-situ pre-sodiation of Prussian blue for the construction of high-performance sodium-ion batteries

Prussian blue and its analogs have attracted increasing attention owing to their stable structure and low cost, especially in the field of sodium-ion batteries. However, the insufficient sodium and high contents of water in the structure greatly hinder their practical applications. Herein, an in-situ pre-sodiation strategy is conducted to realize a one-step transformation of sodium-poor Prussian blue (NP-PB) to sodium-rich Prussian blue (NR-PB) without the introduction of other impurities. The introduced sodium ions take the place of coordination water, resulting in richer sodium ion transport channels and higher structural stability. Thanks to the high sodium content and low water content in the structure, the as prepared NR-PB presents a significantly higher initial coulombic efficiency of 95.18% compared to that of NP-PB (41.93%). When coupled with hard carbon (HC), the NP-PB//HC cell exhibits an ultra-high capacity retention of 93.71% after 300 cycles at a current density of 200 mAh/g. Our work provides guidance for the in-situ transformation of sodium-poor Prussian blue into sodium-rich Prussian blue, which is of great importance for the practical applications of sodium ion batteries.

Carrageenan maintains the contractile phenotype of vascular smooth muscle cells by increasing macromolecular crowding in vitro

BackgroundThe contractile phenotype of vascular smooth muscle cells (VSMCs) results in good diastolic and contractile capacities, and its altered function is the main pathophysiological basis for diseases such as hypertension. VSMCs exist as a synthetic phenotype in vitro, making it challenging to maintain a contractile phenotype for research. It is widely recognized that the common medium in vitro is significantly less crowded than in the in vivo environment. Additionally, VSMCs have a heightened sense for detecting changes in medium crowding. However, it is unclear whether macromolecular crowding (MMC) helps maintain the VSMCs contractile phenotype.PurposeThis study aimed to explore the phenotypic, behavioral and gene expression changes of VSMCs after increasing the crowding degree by adding carrageenan (CR).MethodsThe degree of medium crowding was examined by a dynamic light scattering assay; VSMCs survival and activity were examined by calcein/PI cell activity and toxicity and CCK-8 assays; VSMCs phenotypes and migration were examined by WB and wound healing assays; and gene expression was examined by transcriptomic analysis and RT-qPCR.ResultsNotably, 225 μg/mL CR significantly increased the crowding degree of the medium and did not affect cell survival. Simultaneously, CR significantly promoted the contraction phenotypic marker expression in VSMCs, shortened cell length, decreased cell proliferation, and inhibited cell migration. CR significantly altered gene expression in VSMCs. Specifically, 856 genes were upregulated and 1207 genes were downregulated. These alterations primarily affect the cellular ion channel transport, microtubule movement, respiratory metabolism, amino acid transport, and extracellular matrix synthesis. The upregulated genes were primarily involved in the cytoskeleton and contraction processes of VSMCs, whereas the downregulated genes were mainly involved in extracellular matrix synthesis.ConclusionsThe in vitro study showed that VSMCs can maintain the contractile phenotype by sensing changes in the crowding of the culture environment, which can be maintained by adding CR.Graphical

Berlin Green with tunable iron content as ultra-high rate host for efficient aqueous ammonium ion storage

Prussian blue analogues (PBAs) are regarded as promising cathode materials for ammonium-ion batteries (AIBs) because of their low cost and superb theoretical capacity. However, its inherently poor conductivity and structural collapse can significantly limit the enhancement of rate property and cycling stability. In this work, Berlin Green (BG) electrode materials with similar wool-like clusters were constructed by direct precipitation method to accelerate the kinetic, which realizes outstanding cycling stability. Berlin Green with the appropriate amount of iron (BG-2) has a fast ion transport channel, enhanced structure stability, highly reversible insertion/extraction of NH4+, and fine electrochemical reaction activity. Benefiting from the unique architecture and component, the BG-2 electrode shows an excellent rate performance with a discharge/charge specific capacity of 60.1/59.3 mAh g−1 at 5 A g−1. Even at 5 A g−1, BG-2 exhibits remarkable cycling stability with an initial discharge capacity of 59.5 mAh g−1 and a capacity retention rate of approximately 76% after 30,000 cycles. The BG-2 reveals exceedingly good electrochemical reversibility during the process of NH4+ (de)insertion. BG materials indicate huge potential as a cathode material for the next generation of high-performance aqueous batteries.

Development of fluorescent sensing platform with degradable hydrogel for rapid and ultratrace detection of Cr(VI) in vegetables

Degradable fluorescent film sensors are highly ideal for real-time outdoor detection of heavy metal ions and offer the advantage of preventing secondary contamination, aligning with the principle of sustainable development. In this work, we constructed a degradable fluorescent hydrogel for the specific detection of Cr(VI) ions, utilizing poly(1-pyrene butyric acid) (PPBA) as the sensing moiety and sodium alginate (SA) as the cross-linking substrate. The porous network structure of the PPBA-SA film provided enhanced ion transport channels and active sites, thereby reducing fluorescence response time and augmenting detection sensitivity. The PPBA-SA film exhibited rapid and selective recognition of Cr(VI) ions among a panel of 16 anions and 22 cations, achieving an impressive limit of detection of 1.99 nM. Moreover, we successfully applied this platform to detect Cr(VI) ions in four different vegetable samples. Notably, the PPBA bound with Cr(VI) ions could be effortlessly removed from the film, and the substrate underwent rapid degradation within 24 h, attaining a degradation rate of 72.4 %. This work provides an innovative and effective strategy for fabricating green and sustainable fluorescent sensors.

Carbazole-Based branched Poly(Aryl Piperidinium) membranes for Ultra-Stable anion exchange membrane fuel cells

In the technological development of anion exchange membrane fuel cells (AEMFCs), it is crucial to prepare anion exchange membranes (AEMs) with high conductivity and excellent dimensional stability. This study successfully developed highly branched poly(aryl piperidinium) AEMs by introducing 4,4′-bis(N-carbazolyl)-1,1′-biphenyl as branched linker unit into the poly(p-terphenyl piperidinium) backbone. With the introduction of the carbazole group, the plane-conjugated structure and non-rotatable properties are fully utilised, which effectively reduces the entanglement between the polymer backbones and increases the free volume of the AEMs, hence facilitates the construction of an efficient ion transport channel. The branched structure effectively reduces the water uptake of the membrane which leads to improved dimensional stability. The optimized QPCBP-TP-7 membrane exhibited high conductivity, reaching up to 151.88 mS cm−1 at 80 °C, along with excellent mechanical strength (TS = 42.51 MPa, EB = 13.32 %, wet state) and dimensional stability (SR of 22.9 % at 80 °C). Surprisingly, this membrane also exhibited favorable antioxidant properties (retaining over 97.28 % weight after 96 h in Fenton's reagent at 80 °C), and alkaline stability (retaining over 86.81 % efficacy after 1500 h in 5 M NaOH solution at 80 °C). In AEMFCs applications, the QPCBP-TP-7 membrane achieved peak power density (PPD) up to 616 mW cm−2 with the current density is 1330 mA cm−2 at 80 °C (H2-O2) and the QPCBP-TP-7 membrane remained stable and hardly degraded when operated at constant current of 0.1 A cm−2 (80 °C) over 100 h.

Redox-active NiS@bacterial cellulose nanofiber composite separators with superior rate capability for lithium-ion batteries

Separator is an essential component of lithium-ion batteries (LIBs), which is placed between the electrodes to impede their electrical contact and provide the transport channels for lithium ions. Traditionally, the separator contributes the overall mass of LIBs, thereby reducing the gravimetric capacity of the devices. Herein, a dual-layer redox-active cellulose separator is designed and fabricated to enhance the electrochemical performances of LIBs by introducing NiS. The presented separator is composed of an insulating bacterial cellulose (BC) nanofiber layer and a conductive, and redox-active NiS@BC/carbon nanotubes layer. By using the NiS@BC separator, the discharge capacity of the LiFePO4//Li half battery is enhanced to 117 mAh g-1 at a current of 2C owing to the redox-activity of NiS. Moreover, the functional separator-electrode interface can facilitate the homogenous Li stripping/plating and depress the polarization upon the repeated stripping/plating process. Consequently, the battery containing the redox-active separator exhibits outstanding cycle stability and rate capability. The present study contributes a novel strategy for the developments of functional separators to improve the electrochemical properties of LIBs.

Covalent Organic Framework Enhanced Solid Polymer Electrolyte for Lithium Metal Batteries.

High ionic conductivity, outstanding mechanical stability, and a wide electrochemical window are the keys to the application of solid-state lithium metal batteries (LMBs). Due to their regular channels for ion transport and tailored functional groups, covalent organic frameworks (COFs) have been applied to solid electrolytes to improve their performance. Herein, we report a flexible polyethylene oxide-COF-LZU1 (abbreviated as PEO-COF) electrolyte membrane with a high lithium ion transference number and satisfactory mechanical strength, allowing for dendrite-free and long-time cycling for LMBs. Benefiting from the interaction between bis(triflfluoromethanesulonyl)imide anions (TFSI-) and aldehyde groups in COF-LZU1, the Li+ transference number of the PEO-5% COF-LZU1 electrolyte reached up to 0.43, much higher than that of neat PEO electrolyte (0.18). Orderly channels are conducive to the homogenous Li-+ deposition, thereby inhibiting the lithium dendrites. The assembled LiFePO4|PEO-5% COF-LZU1/Li cells delivered a discharge specific capacity of 146 mAh g-1 and displayed a capacity retention of 80% after 200 cycles at 0.1 C (60 °C). The Li/Li symmetrical cells of the PEO-5% COF-LZU1 electrolyte presented a longer working stability at different current densities compared to that of the PEO electrolyte. Therefore, the enhanced comprehensive performance of the solid electrolyte shows potential application prospects for use in LMBs.
