In this work, the advanced all solid-state block copolymer electrolytes (SBCPEs) for lithium-ion batteries with double conductive phases, poly(ethylene oxide)-b-poly(trimethyl-N-((2-(dimethylamino)ethyl methacrylate)-7-propyl)-ammonium bis(trifluoromethanesulfonyl) imide) (PEO-b-PDM-dTFSI)/LiTFSI, were fabricated, in which the charged PDM-dTFSI block contained double quaternary ammonium cations and the PEO block was doped with LiTFSI. The disordered (DIS) and ordered lamellae (LAM) phase structures were achieved by adjusting the composition of the block copolymer and the doping ratio r. In addition, the presence of the hard PDM-dTFSI block and the formation of the LAM phase structure resulted in a good mechanical strength of the solid PEO-b-PDM-dTFSI/LiTFSI electrolyte, and it could maintain a high level of 104 Pa at 100 °C, which was around 10,000 times stronger than that of the PEO/LiTFSI electrolyte. Based on the good mechanical and electrochemical properties, the PEO-b-PDM-dTFSI/LiTFSI SBCPE exhibited excellent long-term galvanostatic cycle performance, indicating the strong ability to suppress lithium dendrites.

Highly-ordered arrangement of Co(OH)F filaments: Planting flower-like Co(OH)F in conductive membrane substrate accelerating Li+ transfer and redox reaction in Li–S batteries

Here, the conventionally disordered Co(OH)F filaments are rearranged to form highly-ordered flower-like Co(OH)F architectures in a conductive membrane substrate. The important findings contribute to designing delicate nanostructures and improving the catalytic activity of advanced materials for energy applications. The hierarchically porous CNT@NC membrane with CNT as the core and N-doped carbon as the crosslinking shell is scalably designed firstly for strengthening the transport of Li+ and electrons in the electrode, providing an ultrahigh porosity for growing flower-like Co(OH)F on both surfaces and interior of the membrane, as well as offering electrons for the redox reactions through the roots of the Co(OH)F flowers. Furthermore, the ordered Co(OH)F bundles with divergent and open-ended structures provide the catalyst with the broad reaction interface and active sites for polysulfides (LiPSs) anchoring and catalytic conversion at a low energy barrier, significantly facilitating the diffusion of ions and electrolyte in the catalyst, and thus effectively alleviating the shuttle effect. Owing to the synergistic effect between the conductive membrane substrate and the grown Co(OH)F catalyst, the Co(OH)F-CNT@NC cathode generates a high reversible capacity and excellent long-term cycling performance (622 mAh·g−1 at 1C after 600 cycles). Conclusively, the proposed facile strategy provides insights regarding the design of novel cathode materials for high-areal-capacity Li–S batteries.

Manganese-based NASICON structured Na1+2xMnxTi2-x(PO4)3 as promising cathode in aqueous sodium ion battery

Herein, a series of manganese-based NASICON structured Na1+2xMnxTi2-x(PO4)3 (x = 1, 1.2, 1.4, denoted as NMTP, NM1.2T0.8P and NM1.4T0.6P) are obtained by sol-gel method and employed as cathodes for an aqueous sodium ion battery (ASIB). There is no obvious difference in structure among these samples, except for a small amount of impurity phase detected in NM1.4T0.6P. Three as-prepared samples exhibit impressive electrochemical performances, thereinto NM1.2T0.8P possesses the best electrochemical performance with the proper operating potential. NM1.2T0.8P delivers a discharge specific capacity of 68.2, 60.3, 52.2, 45.9 mAh g−1 at 1, 2, 5, 10 C, and still maintain 62.8 mAh g−1 when the current density returns to 1 C. Meanwhile, long-term cycling performance test shows that NM1.2T0.8P displays an initial discharge capacity of 46.4 mAh g−1 and still retains a reversible capacity of 39.1 mAh g−1 at 10 C rate after 300 cycles. Cyclic voltammetry demonstrates that both the diffusion and pseudocapacitance determine the sodium-ion (Na-ion) storage mechanism of NM1.2T0.8P and the pseudocapacitance dominates the charge/discharge processes. Besides, a cathode-limited full cell with NM1.2T0.8P cathode and NaTi2(PO4)3 anode was assembled and shows excellent long-term cycling performance with a capacity retention ratio of 81.9 % at 10 C after 200 cycles. This exploration of manganese-based NASICON structured Na1+2xMnxTi2-x(PO4)3 provides an option for cathode materials of ASIB.

Eco-friendly design of α-zirconium phosphate modified by phytic acid for reinforcing the corrosion resistance of waterborne epoxy coating

Owing to the increasingly stringent environmental regulations, eco-friendly waterborne epoxy (WEP) coating currently gets much attention as an alternative choice of traditional coating. But the intrinsic problems of WEP, including poor barrier property and lack of long-term anticorrosion performance, was a limitation for its application. Herein, α-zirconium phosphate (α-ZrP) was prepared and exfoliated under mild condition. Then α-ZrP after exfoliation was functionalized by eco-friendly phytic acid (PA) molecular and a novel nano-filler (PZ) was obtained. The test results of the XRD, FTIR, SEM, TEM and XPS indicated that the preparation of nano-materials was successful. Through the EIS test, the outstanding barrier property of WEP incorporating with PZ was proved. Moreover, the excellent long-term anticorrosion performance of WEP incorporating with PZ was also proved by the salt spray test.

Microstructure and corrosion behavior of PEO-LDHs-SDS superhydrophobic composite film on magnesium alloy

The MgAl-LDHs film was in situ grown on the PEO film of magnesium alloy by hydrothermal growth method, and the PEO-LDHs-SDS composite film modified by sodium dodecyl sulfate (SDS) was further prepared. The results show that compared with the single-layer PEO film, the PEO-LDHs-SDS composite film exhibits excellent short-term and long-term protection performance, which can be attributed to the blocking effect of the superhydrophobic surface of the composite film, the sealing effect of LDHs on the micropores of the PEO film, and the readsorption and corrosion inhibition of SDS anions.

Engineering Bio-Adhesives Based on Protein-Polysaccharide Phase Separation.

Glue-type bio-adhesives are in high demand for many applications, including hemostasis, wound closure, and integration of bioelectronic devices, due to their injectable ability and in situ adhesion. However, most glue-type bio-adhesives cannot be used for short-term tissue adhesion due to their weak instant cohesion. Here, we show a novel glue-type bio-adhesive based on the phase separation of proteins and polysaccharides by functionalizing polysaccharides with dopa. The bio-adhesive exhibits increased adhesion performance and enhanced phase separation behaviors. Because of the cohesion from phase separation and adhesion from dopa, the bio-adhesive shows excellent instant and long-term adhesion performance for both organic and inorganic substrates. The long-term adhesion strength of the bio-glue on wet tissues reached 1.48 MPa (shear strength), while the interfacial toughness reached ~880 J m−2. Due to the unique phase separation behaviors, the bio-glue can even work normally in aqueous environments. At last, the feasibility of this glue-type bio-adhesive in the adhesion of various visceral tissues in vitro was demonstrated to have excellent biocompatibility. Given the convenience of application, biocompatibility, and robust bio-adhesion, we anticipate the bio-glue may find broad biomedical and clinical applications.

Heterostructured δ-MnO2/Fe2O3 nanoarrays layer-by-layer assembled on stainless-steel mesh was fabricated via a two-step hydrothermal synthesis. Compared to the corresponding individual phases such as δ-MnO2@SSM and Fe2O3@SSM, δ-MnO2/Fe2O3@SSM delivers a high initial discharge capacity of 1821 mAh g−1, and retain 1464 mAh g−1 after 200 cycles at 200 mA g−1, moreover, about 1135 mAh g−1 can still be achieved at 2.0 A g−1 after 500 cycles, demonstrating excellent long-term cycling performance. Furthermore, the composite demonstrates superior rate capability as well, about 503 mAh g−1 can be remained at a high current density of up to 10 A g−1. Besides a comprehensive contribution from electroactive δ-MnO2 and Fe2O3, the significantly enhanced performance is attributed to the unique porous structure and the heterointerfaces that would induce more active sites and improve electronic conductivity. This research reveals that δ-MnO2/Fe2O3@SSM is a promising anode material for advanced LIBs with high energy density and high power density.

Numerous disposable surgical masks (DSMs) were consumed with the development of COVID-19 epidemic. Non-solid products recovered by pyrolysis is more than twenty species with low added value. Therefore, the search for a reasonable carbonization method can not only alleviate the pressure of global plastic pollution, but also produce considerable economic value. Here it is found that microwave cross-linking can promote the substitution of hydrogen atom in the polymer master chain of DSMs by hydrogen atom, which can reorganize the easily cracked DSMs into sp2-hybridized aromatic carbon, it can maintain 51.2 % carbon yield at1000 ℃. The difference between the DSMs-based porous carbon obtained by in-situ and post-processing N doping was further compared, and it was found that the specific surface area of the activated in-situ doped sample (P-SNO@DSMs) was as high as 2278 m2·g−1, which had rich hierarchical pore structure and high heteroatoms doping rate. Benefiting from the synergistic effect of heteroatoms and hierarchical holes, P-SNO@DSMs sulfur cathode delivers a high specific capacity of 1550 mAh·g−1 at 0.1 C and exhibits excellent long-term cycling performance with the smaller capacity decay of 0.13 % per cycle after 400 cycles. In this work, clean and efficient microwave cross-linking not only realized the efficient recovery of waste DSMs, but also the application of the prepared materials can be broadened by adding additional heteroatomic sources in the process of microwave cross-linking.

A robust in-situ catalytic graphitization combined with salt-template strategy towards fast lithium-ions storage

Lithium-ion hybrid supercapacitors (LIHSs) have received significant attention in electrochemical energy-related areas. However, the sluggish anode kinetics hinders the improvement of power density and cycling stability. Herein, an in-situ catalytic graphitization with a salt-template strategy was applied to prepare the porous graphitic carbon nanosheets. The results demonstrated that the addition of KCl led to a higher specific surface area and higher porous structure. The as-prepared potassium-induced porous graphitic carbon flakes (PPGCs) exhibited an electrochemical plateau capacity of 240.1 mAh g −1 and an electrochemical slope capacity of 129.0 mAh g −1 . PPGCs also delivered superior rate performance of 60.8 mAh g −1 even at 5.0 A g −1 , which was much better than graphitic carbon flakes (GCFs) and potassium-induced graphitic carbon flakes (PGCFs). When assembled into LIHSs devices with commercial activated carbon, the energy density reached 75.6 Wh kg −1 , and the power density was as high as 5.05 kW kg −1 . After 10,000 cycles at 5.0 A g −1 , the energy density was maintained at 39.2 Wh kg −1 , revealing excellent long-term cycling performance. This work may provide a promising solution to obtain graphitic carbon with a high graphitization degree and highly porous structure. • In-situ catalytic graphitization incorporated into salt-template strategy was developed. • Porous graphene-like graphitic carbon nanosheets were achieved successfully. • The effect of KCl added before and after hydrothermal procedure was illustrated. • The energy density reached 75.6 Wh kg −1 with 68.4% retention after 10,000 cycles.

Lonicerae flos-derived N, S co-doped graphitized carbon uniformly embedded with FeS2 nanoparticles as anode materials for high performance lithium ion batteries

Metal sulfides still face significant challenges in terms of large volume expansion and poor conductivity as anodes for lithium ion batteries. For the past few years, many researches have shown that the preparation of the composite of metal sulfide and heteroatom doped graphitized carbon with high conductivity has become an effective method to improve its lithium storage performance. In this work, FeS2 @N/S-C composite was successfully synthesized through homogeneously embedding FeS2 nanoparticles into N and S co-doped biomass-derived graphitized carbon, by using Lonicerae flos as carbon source and bio-template. It is worth noting that the introduction of Fe ions effectively enhances the graphitization degree of the N, S co-doped carbon material derived from Lonicerae flos, thus improves the conductivity and stability of the composite. At the same time, the uniform coating of highly conductive carbon effectively inhibits the growth and agglomeration of FeS2 nanoparticles during the process of charge and discharge. Therefore, the FeS2 @N/S-C electrode exhibits large lithium storage capacity, delivers a high capacity of 1259 mA h g−1 at 0.1 A g−1 after 100 cycles, and excellent long-term cycle performance at 1.0 A g−1 (528 mA h g−1 after 1000 cycles). These results indicate that the as-prepared FeS2 @N/S-C composite is a promising anode.

Constructing high-performance N-doped carbon nanotubes anode by tuning interlayer spacing and the compatibility mechanism with ether electrolyte for sodium-ion batteries

The graphitic carbon nitride (g-C3N4) as a promising high-nitrogen carbon material has attracted abundant attentions in energy storage field. In this work, the N-doped carbon nanotubes (N-CNTs) are synthesized through a facile one-step pyrolysis of g-C3N4 precursor assisting by Ni catalyst. The obtained N-CNTs possess unique one-dimensional (1D) nanotubular structure, high conductivity, suitable N-doping around 8.73 ∼ 14.72 at.% and tunable interlayer distance up to 0.462 nm which can accommodate sufficiently Na+. Serving as anodes for sodium-ion batteries (SIBs), the resultant N-CNTs exhibit a promising specific capacity of 290.3 mAh⋅g−1 at 0.05 A⋅g−1 and superior rate capability of 164.5 mAh⋅g−1 at 10 A⋅g−1, as well as excellent long-term cycling performance at 0.5 A⋅g−1 for 1000 cycles. Further kinetic analysis and ex-situ Raman reveal the sodium storage mechanism of N-CNTs, which simultaneously combines the diffusion and the dominated capacitive mechanisms together. According to the first principles, density functional theory (DFT) calculations from the perspective of atomic structure further demonstrate that the superior electrochemical performance of N-CNTs is attributed to the strong adsorption interaction between Na+ in ether-based electrolyte and pyrrolic N site. This work provides a facile method to synthesize N-doped carbon nanotube with remarkable electrochemical performance, which is a promising nanotube-structured anode material for the practical application of SIBs.

Preparation of a Honeycomb-like FeNi(OH/P) Nanosheet Array as a High-Performance Cathode for Hybrid Supercapacitors

Polymetallic transition metal phosphides (TMPs) exhibit quasi-metallic properties and a high electrical conductivity, making them attractive for high-performance hybrid supercapacitors (HSCs). Herein, a nanohoneycomb (NHC)-like FeNi layered double hydroxide (LDH) array was grown in situ on 3D current collector nickel foam (NF), which is also the nickel source during the hydrothermal process. By adjusting the amount of NaH2PO2, an incomplete phosphated FeNi(OH/P) nanosheet array was obtained. The optimized FeNi(OH/P) nanosheet array exhibited a high capacity up to 3.6 C cm−2 (408.3 mAh g−1) and an excellent long-term cycle performance (72.0% after 10,000 cycles), which was much better than FeNi LDH’s precursor. In addition, the hybrid supercapacitor (HSC) assembled with FeNi(OH/P) (cathode) and polypyrrole (PPy/C, anode) achieved an ultra-high energy density of 45 W h kg−1 at a power density of 581 W kg−1 and an excellent cycle stability (118.5%, 2000 cycles), indicating its great potential as an HSC with a high electrochemical performance.

Design micro-nano structure and composite conductive carbon materials have important influence to improve the stability of structure and accelerate electron transportation. Here, two identified manganese carbonate with spherical and ellipsoidal shape were modified by graphene and carbon nanotubes, exhibiting high discharge capacity and excellent long-term cyclic performance as anodes for lithium storage. The graphene/ellipsoidal MnCO3 sample delivers a reversible capacity of 1110 mAh g−1 at 1000 mA g−1 after 500 cycles. The outstanding electrochemical performance and facile synthesize route suggest the validity of our method, and enable the modified MnCO3 composites to be promising anodes for LIBs.

Ti-substituted O3-type layered oxide cathode material with high-voltage stability for sodium-ion batteries

O3-type layered transition metal oxides (NaxTMO2) have attracted extensive attention as a promising cathode material for sodium-ion batteries because of their high capacity. However, the irreversible phase transition especially cycled under high voltage remains a concerning challenge for NaxTMO2. Herein, a Ti-substituted NaNi0.5Co0.2Mn0.3O2 cathode with strongly suppressed phase transition and enhanced storage stability is investigated. The Ti substitution effectively inhibits the irreversible phase transition and alleviates the structural change even charged to 4.3 V during the repeated Na+ deintercalation process. After storing in air or water, the original O3 phase structure of the material is integrally maintained without the generation of impurity phase. As a result, the as-prepared material shows excellent long-term cycle stability and rate performance when charged to a high voltage of 4.3 V.

Analysis of the simultaneous adsorption mechanism of ammonium and phosphate on magnesium-modified biochar and the slow release effect of fertiliser

To decrease the eutrophication caused by nitrogen (N) and phosphorus (P) in water, magnesium-modified corn stalk biochar (MgB) was prepared under the synergistic impact of the multi-pyrolysis temperatures and Mg2+ contents for the co-adsorption of ammonium (NH4+-N) and phosphate (PO43−). The co-adsorption mechanism, slow-release performance and plant application of MgB were systematically studied. The results showed that pyrolysis temperatures (350–650 °C) and Mg2+(0–3.6 g/L) contents not only altered the physicochemical properties of biochar, but also significantly affected the adsorption efficacy of MgB. The adsorption of NH4+-N and PO43− was in accordance with Langmuir–Freundlich and pseudo-second-order kinetic models (Qmax = 37.72 and 73.29 mg/g, respectively). Based on the characteristics, adsorption kinetics and isotherms results, the adsorption mechanism was determined and found to mainly involve struvite precipitation, ion exchange, and surface precipitation or electrostatic attraction. Compared with the leaching performance of chemical fertilizers (CF), after adsorption of NH4+-N and PO43− (MgB-A), MgB had a more stable pH and lower conductivity. Leaching of NH4+-N and PO43− by MgB-A was controlled by both the diffusion mechanism and the dissolution rate of struvite and Mg-P. The excellent long-term slow-release performance and abundant Mg2+ of MgB-A promoted the growth of Zea mays L. and Lolium perenne L. Overall, this study suggested that MgB could realize a win–win outcome of struvite biochar-based fertiliser production and wastewater treatment.

A promising microalgal wastewater cyclic cultivation technology: Dynamic simulations, economic viability, and environmental suitability

The microalgal wastewater cyclic cultivation technology (AWC2T) proposed in this study helps address the challenges surrounding water scarcity and ecological sustainability in a clean, resource-efficient, and affordable manner. A novel microalgae growth model (AGM) elucidating the growth mechanisms of microalgae in the AWC2T system was established for dynamic simulations and design optimization. The recycled wastewater accelerated the growth rate of microalgae, and increased biomass and lipids content by 11% and 37.65%, respectively, after 8 batches of cultivation. The accumulated soluble algae products (SAPs) enhanced microalgae growth by providing nutrients and regulating metabolism. In addition, scenario simulations illustrated the excellent long-term performance of the AWC2T system. 100% recycling of microalgal wastewater could save 0.3% N and 54.36% P. The techno-economic analysis (TEA) and life cycle assessment (LCA) explored how economic and sustainability principles can be embedded into the life cycle of microalgae production. The AWC2T led to outcomes vastly superior to non-cyclic technology by enabling the high-level recovery of resources, providing substantial benefits, enhancing contingency and risk resistance, and offsetting a host of unintended environmental effects.

Constructing heterostructures is an important approach to develop high-performance anode materials for sodium ion batteries (SIBs). The abundant phase interfaces provide numerous defects and active sites for rapid electron/ion transport. Herein, CoSe2 ⊂ NC@NC/MoS2 heterostructures are prepared through a multi-step reaction strategy, CoSe2 nanoparticles served as the coating shells for MoS2 cores are anchored in carbon frameworks.

The DFT calculation proves that the electronic distribution of heterostructures is reconstructed with enhanced conductivity. The kinetic analysis, mechanism characterizations and full-cells tests exhibit the synergistic reaction mechanism among different components and practical application prospects. The heterostructure also shows more rapid ions diffusion kinetics than single components.

Effect of video game experience on the simulated flight task: the role of attention and spatial orientation

ABSTRACT Objective In this study, we investigated the advantages of attention allocation and spatial orientation among video game players (VGPs) and non-video game players (NVGPs) and explored the performance differences between the two groups in flight simulations. Method Thirty candidates from a Chinese university were categorised as VGPs and NVGPs before participating in all tests. Results The comparison of flight performance and eye movement indicators between the two groups showed that the flight performance of VGPs was significantly better than that of NVGPs. We then found that an attention shift task and group factors predicted flight performance during take-off, while spatial orientation and tracking tasks have direct and indirect effects on cruise task performance, respectively. Eye movement indicators can directly predict flight performance to a certain extent. Conclusion We believe that the transfer effect of game experience in simulated flight tasks assisted VGPs in using top-down processing strategies in the flight process, and in better allocating cognitive resources. KEY POINTS What is already known about this topic: The advantages of attention allocation and spatial orientation among video game players (VGPs) and non-video game players (NVGPs). This difference not only caused by gaming experience, but also comes from the interaction of gaming experience and individual differences. The VGPs perform better on simulated flight mission. We speculated that gaming practice had assisted VGPs in using top-down processing strategies in the flight process, and in better allocating cognitive resources. VGPs did not depend solely on low-level cognitive abilities to finish tasks, but rather could rapidly understand the relevant situation and task in order to choose a proper attention allocation strategy, that visual search patterns must be adapted according to different situations, as opposed to reliance on a single parallel or sequence search. What this topic adds: The promotional effects of gaming experience occurred in high-level cognitive processing, but this effect was also observed in low-level ability tests. The key to promoting and maintaining excellent long-term performance are comprehensive cognitive skills, advanced cognitive skills, the establishment of mental models, and adaptive top-down processing strategies. The aviation training system design should not stop at elemental training to improve general cognitive abilities, but should be a comprehensive ability-training game in order to improve training efficiency for pilots. In order to establish a cognitive ability video game training system for pilots in the future, further exploration is needed to understand whether the transfer effect would occur in real world flight missions.

Perovskite strontium vanadate nanoparticle as an ideal fast charging anode material in lithium-ion batteries

Current lithium ion batteries (LIBs) are unable to fulfill electric vehicles’ fast charging requirement due to the poor rate performance of commercial LIBs anode materials (graphite and Li4Ti5O12). Thus, developing novel anode materials in LIBs to address the issue of long charging time is highly desirable. In this work, perovskite strontium vanadate (SrVO3) has been investigated as an anode material for LIBs. SrVO3 nanoparticles (SVO NPs) are prepared by gel-sol method and their fast charging performances are studied in the first time. SVO NPs display a safe lithiation potential (∼0.4 V), a high capacity of 320.2mAhg−1 at 100 mA g−1, a stable capacity of 171.8mAhg−1 at 10000 mA g−1, and excellent long-term fast-charging performance (capacity of 214.6 mAh g−1 at 5000 mA g−1 after 1000 cycles with a high capacity retention of 93.2%). This paper opens up a new opportunities to develop high fast charging LIBs.

Realizing ultrahigh-voltage performance of single-crystalline LiNi0.55Co0.15Mn0.3O2 cathode materials by simultaneous Zr-doping and B2O3-coating

Improving the high-voltage stability of cathode materials is a new strategy to enhance the energy density of lithium-ion batteries (LIBs) in recent years. However, as a traditional cathode material, the low reversible capacity at high cut-off voltages (≥ 4.3 V) greatly restricts the application of LiCoO2. Herein, we have rationally synthesized a novel single-crystalline LiNi0.55Co0.15Mn0.3O2 cathode material (Z-NCM@B) by using the synergistic effect of Zr-doping and B2O3-coating. Excitedly, the modified Z-NCM@B cathode material shows improved high-voltage stability and excellent long-term cycling performance. Furthermore, it is revealed that the stronger ZrO bond formed by Zr4+ dopant can stabilize the crystal structure and promote the migration of Li+ in the cathode materials. Meanwhile, the uniform B2O3 coating layer effectively suppresses the material corrosion by electrolyte and reduces the loss of transition metal ions during the charge/discharge cycle process. As anticipated, the Z2-NCM@B2 || graphite pouch-type full cell exhibits an advanced capacity retention of 96.9% over 250 cycles at an operating voltage of 4.2 V, while the capacity retention of the pristine NCM is only 88%. Besides, the Z2-NCM@B2 coin-cell retains a discharge capacity of 145.2 mA h g−1 at 1 C with a satisfactory capacity retention of 79.2% after 100 cycles within a broad voltage range between 2.95 and 4.7 V, which is much superior than that for the pristine NCM (130.9 mA h g−1, 70.9%). This synergistic modification strategy offers a reference for the practical application of NCM cathode materials with high-voltage stability and long-term cycling performance in LIBs.
