As we've already noted, the Bronco Sport is the runt of this litter in terms of length, stretching 7. But it is also the widest and tallest in the class, at Those extremes land the Bronco Sport smack in the middle of the class in terms of overall space efficiency interior people and cargo space divided by the volume of the exterior box. Although it borrows the Escape's drivetrains, routing the exhaust to stay out of harm's way when off-road and tuning the engine power and torque slightly to suit the Bronco Sport's different mission alter the Escape's engine specs.

That, plus the added gear to keep it moving safely through the rough stuff means the Bronco Sport ranks a bit lower on the weight-to-power list than the Escape. But in its 2. At the other end of the spectrum, the wee little 1. Many adventurous pursuits require toys that need to ride along behind your adventuremobile, and the Bronco Sport is aimed at adventurers. And while the 1.

Perhaps it's the twin-clutch rear axle or the shorter final-drive gearing, but you'll need to go a bit smaller on the travel-trailer or boat maybe 16 feet tops for either.. Both numbers are still class-competitive and will allow you to tow a small pop-up camper, a pair of jet-skis or snowmobiles, a quad-runner, or another like-sized object.

Herein, we report diatom bio-silica as a biomaterial additive to enhance the output performance of cellulose nanofibril CNF -based TENGs. Diatom frustules DFs , which are tribopositive bio-silica having hierarchically porous three-dimensional structures and high surface area, have hydrogen bonds with CNFs, resulting in enhanced electron-donating capability and a more roughened surface of the DF�CNF composite film. The DF�CNF biocomposite film is mechanically strong, electron-rich, low-cost, and frictionally rough.

In addition, a cytotoxicity study and biocompatibility tests on rabbit skin suggested that the DF�CNF composite was biologically safe. This study not only suggests high output performance of biomaterial-based TENGs but also presents the diverse advantages of the DFs in human body-related applications such as self-powered health monitoring masks, skin-attachable power generators, and tactile feedback systems.

However, the absence of O2 at tumor sites hinders the sustained response of photosensitizers. Here, we develop a recycled cerium oxide CeO2 catalase nanozyme-loaded hyaluronic acid nanovesicle to address the hypoxic tumor microenvironments and targeted delivery of the photosensitizers [indocyanine green ICG ] to tumors.

A polysaccharide complex effectively modifies the surface of a polyethylenimine phenylboronic acid nanostructure to achieve the CeO2 nanozyme-loading nanovesicles that exhibit both tumor-targeted enhancement and an improved hypoxic microenvironment. The in vitro synergistic tests and tumor suppression rate tests indicated that the cerium oxide nanozyme significantly improves the outcomes of PDT via cerium-element valence state recycling and hypoxia improvement, thus enhancing the tumor suppression efficiency.

Carrier-free pure drug self-assembled nanosystems have been proposed as a promising strategy for synergetic anticancer therapy. The molecular dynamics simulation elucidates the possible coassembly mechanism that the coplanar arrangement of BA-S-S dimeric may be primarily responsible for the formation of a long lamella-like or spherical morphology.

The assembled prodrugs exhibited remarkable GSH-responsive property and multiple favorable therapeutic features, leading to enhanced synergistic antitumor efficacy without noticeable toxicity. This work provides a promising insight for exploring the pure drug self-assembly behavior and construction of GSH-responsive carrier-free triterpenoid prodrugs toward improved multiple combination antitumor therapies.

Controllable drug release is promising for fighting against antimicrobial resistance, which is a critical threat to human health worldwide. Herein, new hyaluronidase-responsive conjugated oligo thiophene ethynylene OTE -covalently modified hyaluronic acid OTE-HA nanoparticles for on-demand release of antimicrobial agents are reported. The OTE-HA nanoparticles avoid bactericide premature leakage and effectively block the dark cytotoxicity of the OTE section, possessing excellent biocompatibility.

Importantly, the OTE section could effectively break cell membranes, leading to bacterial death. The half-maximal inhibitory concentration of the nanoparticles against MRSA is 3. The great antibacterial activity of OTE-HA nanoparticles against Gram-positive bacteria Streptococcus pneumoniae further confirms the controllable bactericide delivery mechanism. OTE-HA nanoparticles coated on a surface can also effectively inhibit the growth of bacteria, which holds a remarkable promise in biomedical applications.

Therefore, this work provides a favorable strategy of on-demand and in situ drug release for sterilization and defeating antimicrobial resistance. Rheumatoid arthritis RA is an angiogenic and chronic inflammatory disease. One of the most extensively used first-line drugs against RA is methotrexate MTX , but it shows poor solubility, short in vivo circulation, and off-target binding, leading to strong toxicity.

To overcome these shortcomings, the present study loaded MTX into nanoparticles of human serum albumin modified with mannose MTX-M-NPs to target the drug to neutrophils. MTX-M-NPs were prepared, and their uptake by neutrophils was studied using laser confocal microscopy and flow cytometry. A chick chorioallantoic membrane assay was used to assess their ability to inhibit angiogenesis. The pharmacokinetics and tissue distribution of MTX-M-NPs were investigated using fluorescence microscopy and high-performance liquid chromatography.

Their pharmacodynamics was evaluated in a rat model with arthritis induced by collagen. The retention of NPs was promoted by mannose-derived coating in arthritic joints. In conclusion, these NPs can prolong the in vivo circulation of MTX and target it to the sites of inflammation in RA, reducing drug toxicity.

MTX-M-NPs allow the drug to exert its intrinsic anti-inflammatory, antiangiogenic, and analgesic properties, making it a useful drug delivery system in RA. This work demonstrates the application of hyaluronan-conjugated nitrogen-doped carbon quantum dots HA-nCQDs for bioimaging of tumor cells and illustrates their potential use as carriers in targeted drug delivery. Quantum dots are challenging to deliver with specificity, which hinders their application.

To facilitate targeted internalization by cancer cells, hyaluronic acid, a natural ligand of CD44 receptors, was covalently grafted on nCQDs. To demonstrate the specificity of HA-nCQDs toward human tumor cells, patient-derived breast cancer tissue with high-CD44 expression was implanted in adult mice. With either local or systemic injection, we achieved a high level of tumor specificity judged by a strong signal-to-noise ratio between the tumor and the surrounding tissue in vivo.

Overall, the results show that HA-nCQDs can be used for imaging of CDspecific tumors in preclinical models of human cancer and potentially used as carriers for targeted drug delivery into CDrich cells. Malaria is one of the deadliest infectious diseases threatening half of the world population. With the deterioration of the parasiticidal effect of the current antimalarials, novel approaches such as screening of more specific inhibitors and targeted delivery of drugs have been under intensive research.

Herein, we prepare hollow mesoporous ferrite nanoparticles HMFNs of nm with ferromagnetic properties using a one-pot hydrothermal reaction. A magnetically targeted drug-delivery system coloaded with artemisinin in the inner magnetite shell and heparin on the outer mesoporous shell [email protected] HEP is developed. Specific targeting of the magnetic nanoparticles to the parasite-infected erythrocytes is achieved by the attraction between the HMFNs and hemozoin paramagnetic , a vital metabolite of plasmodium in the erythrocytic stage.

With the hemozoin production reaching the maximum during the schizont period of the parasite, [email protected] HEPs are adsorbed to the infected red blood cells iRBCs , which not only interferes with the release of merozoites but also significantly enhances the inhibitory efficacy due to the increased local concentration of artemisinin.

Subsequently, the heparin coated on the surface of the nanoparticles can efficiently interfere with the invasion of freshly released merozoites to new RBCs through the specific interaction between the parasite-derived ligands and heparin, which further increases the inhibitory effect on malaria. As a cluster of heparin, heparin-coated nanoparticles provide stronger blocking capability than free heparin, resulting from multivalent interactions with surface receptors on merozoite.

Thus, we have developed a HMFN-based delivery system with considerable antimalarial efficacy, which is a promising platform for treatment against malaria. Because of this random assembly process, a significant discrepancy exists in the distribution of a modified DNA film on different electrodes, which greatly affects the reproducibility of a biosensor. In this study, a porous bovine serum albumin BSA layer was first modified on the electrode surface, which can improve the position distribution and spatial orientation of the self-assembly ssDNA probe.

It was then coupled with hyperbranched rolling circle amplification to develop the high-reproducibility-and-sensitivity ECL biosensor for human papillomavirus 16 E6 and E7 oncogene detection. There is a linear relationship between the signal and the target concentration range from 10 fM to 15 pM, and the detection limit is 7.

After the BSA modification step, the relative standard deviation was reduced from 9. Photothermal therapy is a new type of tumor therapy with great potential. An ideal photothermal therapy agent should have high photothermal conversion effect, low biological toxicity, and degradability. The development of novel photothermal therapy agents with these properties is of great demand. In this study, we synthesized boron quantum dots BQDs with an ultrasmall hydrodynamic diameter.

Both in vitro and in vivo studies show that the as-synthesized BQDs have good biological safety, high photoacoustic imaging performance, and photothermal conversion ability, which can be used for photoacoustic imaging-guided photothermal agents for tumor treatment. Our investigations confirm that the BQDs hold great promise in tumor theranostic applications.

In this study, we present a modulated synthesis nanocrystalline defective UiO metal�organic framework as a potential chloroquine diphosphate CQ delivery system.

Increasing the concentration of hydrochloric acid during the modulated synthesis resulted in a considerable increase of pore volume, which enhanced the CQ loading in [email protected] composites.

Drug release tests for [email protected] composites have confirmed prolonged CQ release in comparison with pure CQ. Cytotoxicity tests proved that the CQ loaded on the defective UiO cargo resulted in increased viability of cardiac cells H9C2 as compared to incubation with pure CQ.

The experimental results presented here may be a step forward in the context of reducing the cardiotoxicity CQ. The energy available in the ambient vibrations, magnetic fields, and sunlight can be simultaneously or independently harvested using universal architecture.

The universal harvester design is shown to effectively convert ambient magnetic fields, vibration, and light into electricity. The architecture is composed of a perovskite solar cell integrated onto a magnetoelectric composite cantilever beam.

The efficiency of the large-area perovskite solar cell is shown to reach The magnetoelectric composite beam is designed to include the effect of the mass and volume of the solar cell on power generation. Results demonstrate that universal energy harvester can simultaneously capture vibration, magnetic fields, and solar irradiation to provide an ultrahigh-power density of The total power generated by the multienergy harvester, including vibration, magnetic field, and solar stimuli, is These results will have a tremendous impact on the design of the power sources for Internet of Things sensors and wireless devices.

Perovskites are one of the efficient catalysts for the oxygen evolution reaction OER , and they belong to the primary ABO3 in which the A site and B site are site-substituted, and oxygen vacancies are introduced. Further improvement of these complex perovskites is the next necessary topic for specific applications. Herein, two complex perovskites, La0. This is based on the fact that the increased content of oxygen vacancies and coordination can balance the oxygen vacancy and B-site element oxidation state.

Monoacetin was synthesized using a novel green method in which acetonitrile was hydrolyzed and then esterified with glycerol over Cu�Cr phosphates under the CO2 atmosphere. Monoacetin was synthesized with high yield In this process, acetonitrile can react with water to form acetamide and further undergo esterification with glycerol.

There are two main reasons for obtaining monoacetin in high yield: 1 the interaction of CO2 with high-temperature liquid water enhances the acid strength of the reaction system and then promotes the activation of acetonitrile; and 2 the introduction of Cr species causes a synergistic effect between Cu and Cr species to adjust the acidity and basicity of the catalyst.

The introduction of Cr species also causes the surface oxygen to be transformed into lattice oxygen to enhance the basicity of the catalyst. These bimetallic phosphate materials may provide a new pathway for the application of acid�base bifunctional catalytic reactions.

However, LLZO undergoes protonation under the influence of moisture-forming Li2CO3 layers, thereby affecting its structural and transport properties. These findings suggest that measurements on a single LLZTO variant sample do not lead to a general conclusion for all garnets to guide the field toward better materials. In contrast, each composition has to be analyzed exclusively to understand the interplay of composition, structure, and exchange kinetic properties.

Oxygen redox has recently emerged as a lever to boost the specific energy density of layered sodium transition metal oxide cathode materials.

However, the oxygen redox reaction is universally confronted with concomitant issues such as irreversible lattice oxygen loss and parasitical electrolyte degradation, thus debilitating cycling stability. Herein, a novel F-substituted layered structure P2-Na0. Such results are nontrivial as this system only contains the low-cost Mn transition metal element.

In addition, a higher oxygen vacancy formation energy for the F-substituted structure was demonstrated via density functional theory calculations. Anionic substitution could therefore be an impactful solution to boost reversible oxygen redox chemistry for layered sodium oxide cathodes.

Low-temperature hydrothermal epitaxial growth and topochemical conversion TC reactions offer unexploited possibilities for the morphological engineering of heterostructural and non-equilibrium shape photo catalyst particles. The dissolution of the Bi4Ti3O12 platelets proceeds faster from the lateral direction, whereas the epitaxial growth of SrTiO3 occurs on both bismuth-oxide-terminated basal surface planes of the Bi4Ti3O12 platelets.

A plausible Z scheme is proposed to describe the charge-transfer mechanism during the photocatalysis. Electrochemical oxygen reduction in a selective two-electron pathway is an efficient method for onsite production of H2O2. State of the art noble metal-based catalysts will be prohibitive for widespread applications, and hence earth-abundant oxide-based systems are most desired.

These novel compounds are isostructural with the parent Sr0. The presence of Na stabilizes O vacancies created on doping, and the transition metal ions provide catalytically active sites. Electrochemical parameters estimated from Tafel and Koutechy�Levich plots suggest a two-electron transfer mechanism, indicating peroxide formation.

Of all the dopants, Ni imparts the maximum selectivity and efficiency as well as highest rate of formation of H2O2 at 1. It is difficult to achieve higher energy density with the existing system of lithium Li -ion batteries.

As a powerful candidate, Li metal batteries are in the renaissance. Unfortunately, the uncontrolled growth process of Li dendrites has limited their actual application. Hence, inhibiting the formation and spread of Li dendrites has become an enormous challenge.

Herein, a novel composite separator is developed with functionalized boron nitride nanosheet modification layer as a Li-ion regulator to regulate Li-ion fluxes. The composite separator contains abundant polar groups and nanoscale channels and could achieve uniform electrochemical deposition via the lithiophilic effect and shunting action.

Under the synergy influence of the lithiophilic effect and shunting action, Li dendrites are effectively suppressed. As proof, the Li Li symmetrical cells with composite separators can circulate steadily for a long time under high current densities 10 mA cm�2, h. Tens of thousands of plastics produced by people have caused incalculable harm to the environment.

At the same time, the consumption of energy is becoming more and more serious, and the use of fossil energy to generate electricity has caused further damage to the environment.

It is a good way to recycle waste plastics and make energy collection and generation devices based on them. Here, a triboelectric nanogenerator TENG based entirely on waste plastic bags is proposed. The output performance was improved by gilding the back of the plastic films as a conductive electrode. Under different conditions, three different types of TENGs were tested. After further integration with supercapacitors, the integrated system can drive multiple commercial LEDs, and it can be used as an antitheft device to achieve early warning.

This study realizes the integration of a TENG and energy storage devices, and as a TENG is based entirely on waste plastic bags, it not only realizes the recycling of plastics but also further realizes power generation, which can alleviate energy consumption to some extent.

Molecular doping is a powerful tool to tune the thermoelectric TE properties of solution-processed semiconductors. The doped composites show an n-type character and an in-plane TE figure of merit ZT , exceeding the values obtained with the doped polymers.

The n-type composites show good solution processability and relatively stable Seebeck coefficients upon air exposure for 8 months. Self-powered devices have great potential in daily applications ranging from portable electronics to wearable body sensors, yet their working lifetime and performance are normally limited by the low energy density of the power unit as well as additional resistive losses induced by connections between electronic and power moieties.

Herein, we report an effective programmable laser-assisted fabrication of facilely integrated microphotocapacitors integrated devices of solar cells and microsupercapacitors, mPCs exhibiting high output voltage and energy density These devices have also shown good stability stable operation over cycles, 2.

Kesterite-based thin-film solar cells TFSCs have recently gained significant attention in the photovoltaic PV sector for their elemental earth abundance and low toxicity. An inclusive study from the past reveals basic knowledge about the grain boundary GB and grain interior GI interface. However, the compositional dependency of the surface potential within GBs and GIs remains unclear. The present work provides insights into the surface potential of the bulk and GB interfaces.

The tin Sn composition is sensitive to the absorber morphology, and therefore, it significantly impacts absorber and device properties.

The absorber morphology improves with the formation of larger grains as the Sn content increases. The secondary ion mass spectroscopy analysis reveals the altered distribution of sulfur S and sodium Na with higher near-surface accumulation. The synergistic outcome of the increased density of defects and the accumulation of S near the interface provides a larger GB and GI difference and expedites carrier separation improvement.

We developed a heterojunction photocathode, [email protected] , based on the wrapping of CdS nanoparticles by the MoS2 nanocrystals. The difference between two modes in the Raman spectrum of MoS2 indicates the formation of few-layer MoS2. The photoelectrochemical performance of the heterojunction photocathode was excellent. Photocatalytic H2 evolution from ethanol dehydrogenation is a convenient strategy to store solar energy in a highly valuable fuel with potential zero net CO2 balance.

We demonstrate these materials to provide outstanding hydrogen evolution rates under UV and visible illumination. The origin of this enhanced activity is extensively analyzed. Additional steady-state photoluminescence PL spectra, time-resolved PL spectra TRPLS , and electrochemical characterization prove such heterostructures to result in enlarged lifetimes of the photogenerated charge carriers. In addition, we probe small changes of temperature to strongly modify the photocatalytic activity of the materials tested, which could be used to further promote performance in a solar thermophotocatalytic reactor.

Biocidal nanothermite composites show great potential in combating biological warfare threats because of their high-energy-release rates and rapid biocidal agent release. Despite their high reactivity and combustion performance, these composites suffer from low-energy density because of the voids formed due to inefficient packing of fuel and oxidizer particles.

Oxidation timescale analyses suggest that nSi addition can promote initiation due to faster oxygen transport through the oxide shell of Si nanoparticles. Oxygen evolution reaction OER is a bottleneck process in the water-splitting 14 Ft Flat Bottom Boat Capacity Site module for sustainable and clean energy production. Transition metal-based electrocatalysts can be effective as water-splitting catalytic materials because of their appropriate redox properties and natural abundance, but the slow kinetics because of strong adsorption and consequently slow desorption of intermediates on the active sites of catalysts severely hamper the dynamics of the released molecular oxygen and thus remains a formidable challenge.

Such a surface and structural modification and uniform distribution at the nanoscale length are indeed worth considering to selectively tune the catalytic potential and further modernize the electrode materials for the challenging OER process. The potential of Na�CO2 batteries as a viable energy storage technology was demonstrated. Like no other sulfur host material, polyacrylonitrile-derived sulfurized carbon SPAN promises improved electrochemical performance for lithium�sulfur batteries, based on its compatibility with carbonate solvents and ability to prevent self-discharge and shuttle effect.

Our simulations emulate the discharge voltage observed in experiments for the first discharge, which reveals that sulfur follows multiple reduction pathways based on its interaction with the carbon backbone. Sulfur reduction takes place above 1. Below 1. This work improves understanding of lithiation mechanisms in sulfurized carbon, which is useful for rationally designing SPAN synthesis pathways tailored to increase sulfur loading and enhanced electrochemical performance.

Heterogeneous electrocatalytic reactions only occur at the interface between the electrocatalyst and reactant. Therefore, the active sites are only necessary to be distributed on the surface of the electrocatalyst.

It was found that the coordination of Co on the PPy ring tuned the final carbon electrocatalyst into a catalyst with a CoNx moiety-rich surface. The pyrolysis of the cobalt-containing precursor tends to proceed toward a characteristic of a higher sp2 carbon content, a higher surface area, and more nitrogen as well as active nitrogen sites than its metal-free counterpart.

The most distinguished feature for such a catalyst is that the truly most active component is only distributed on the surface, in contrast with that of the conventional metal�N-based catalyst present throughout the bulky structure.

Especially, the electrocatalytic activity toward oxygen evolution reaction OER has been investigated experimentally and theoretically. The results showed that the OER performance of the carbon-based electrocatalyst was remarkably boosted after the introduction of Co with an overpotential decrease from to mV at 10 mA cm�2. The apparent activation energy measurements revealed that the metal-rich surface contributed to overcome the energy barrier for OER.

In addition, density functional theory calculations have been conducted to explain the correlated OER mechanism. This study is expected to provide an effective strategy for the design and the synthesis of highly active metal�nitrogen-type electrocatalysts with a high metal loading for various electrocatalytic reactions. Covalent triazine frameworks CTFs are promising electrodes for rechargeable batteries due to their adjustable structures, rich redox sites, and tunable porosity.

However, the CTFs usually exhibit inferior electrochemical stability because of the inactivation of the unstable radical intermediates. Here, a methylene-linked CTF has been synthesized and evaluated as a cathode for rechargeable lithium-ion batteries.

Additionally, the methylene groups provided extra redox-active sites. As a result, high capacity and cycling stability were achieved.

This work inspires the rational modulation of the radical intermediates to enhance the electrochemical performance of organic electrode materials for the next-generation energy storage devices. Layered rare-earth hydroxides LREHs , as a series of special lamellar compounds having a similar structure to layered double hydroxides LDHs , are becoming a new type of catalyst materials.

Imidazole, benzimidazole, and triazole groups were functionalized on the side chains of poly phenylene oxide , respectively. Each azole group is categorized by their N-substituent into two types: unsubstituted and methyl-substituted azoles. It was also revealed that higher pKa of azoles enhanced the PA retention and the fuel cell performance.

Based on the experimental results of PA retention and density functional theory calculations, the PA loss mechanism was also proposed. Solid oxide photoelectrochemical cells SOPECs with inorganic ion-conducting electrolytes provide an alternative solution for light harvesting and conversion. Exploring potential photoelectrodes for SOPECs and understanding their operation mechanisms are crucial for continuously developing this technology.

It was found that the photoresponse of ceria-based thin films can be tuned both by Sm-doping-induced defects and by the heating temperature of SOPECs. The whole process was found to depend on the surface electrochemical redox reactions synergistically with the bulk photoelectric effect.

Samarium doping level can selectively switch the open-circuit voltages polarity of SOPECs under illumination, thus shifting the potential of photoelectrodes and changing their photoresponse. The role of defect chemistry engineering in determining such a photoelectrochemical process was discussed.

Transient absorption and X-ray photoemission spectroscopies, together with the state-of-the-art in operando X-ray absorption spectroscopy, allowed us to provide a compelling explanation of the experimentally observed switching behavior on the basis of the surface reactions and successive charge balance in the bulk. In this study, the covalent bonding of linear poly ionic liquid s PILs with covalent organic frameworks COFs was accessed by copolymerization of a vinyl-decorated COF with 4-vinylbenzyl chloride, followed by quaternization with tertiary amines.

The resultant PIL�COF composite by anchoring a proper content of vinyl sites on the COF-based comonomer retains the crystallinity and porosity, thereby facilitating access of the reactants to the catalytic active sites. As a proof of concept, the dehydrative transformation of sorbitol into isosorbide was selected as a benchmark reaction, whose rate improved significantly in the presence of PIL�COF These findings provide the basis for a novel design concept for achieving both efficient and stable IL catalysis.

Due to the existence of coordination water molecules in 1, however, its energy density was limited, which led to the insufficient detonation performance. To further improve its detonation performance, [Cu H2BTI NO3 ]n 2 was then obtained by substituting the coordinated water molecule in 1 with nitrate through the coordination substitution reaction under acidic conditions.

The structures of two ECPs were respectively characterized using X-ray single-crystal diffraction, and the theoretical density of 2 2. Thermogravimetric analyses showed that 2 has a one-step rapid weight loss process compared with the two-step slow weight loss process of 1. The theoretical calculations indicated that the detonation performances of 2 were better than those of 1.

Moreover, the promotion effects of two ECPs on the combustion decomposition of ammonium perchlorate were studied using a differential scanning calorimetry method. In lithium-ion batteries LIBs , conversion-based electrodes such as transition-metal oxides and sulfides exhibit promising characteristics including high capacity and long cycle life.

However, the main challenge for conversion electrodes to be industrialized remains on voltage hysteresis. In this study, Mn3O4 powder was used as an anode material for LIBs to investigate the root cause of the hysteresis. Furthermore, results revealed that the formation of disparate phase distribution during lithiation and delithiation could be the root cause of the intrinsic overpotential of Mn3O4.

It was expected that improving the diffusion behaviors of the systems could eliminate the voltage hysteresis of Mn3O4. In summary, this paper provides an explicit insight into the hysteresis for conversion-based Mn3O4 that could also be applied to other oxide systems and very crucial to reduce energy loss for commercializing oxides as anode materials in LIBs. Understanding the electrochemical reactions taking place in composite electrodes during cell cycling is essential for improving the performance of all-solid-state batteries.

However, comprehensive in situ monitoring of Li distribution, along with measurement of the evolution of degradation, is challenging because of the limitations of the characterization techniques commonly used. This study demonstrates the observation of Li distribution and degradation in composite cathodes consisting of LiNi0. The evolution of the nonuniform reaction of NCA particles during charge and discharge cycles was successfully visualized by mapping fragments containing Li.

The fusion of different electroactive components of lithium-ion batteries LIBs sometimes brings exceptional electrochemical properties. We herein report the reduced graphene-oxide rGO -coated [email protected] nanofibers [email protected] G NFs formed by the synergistic fusion of three different electroactive components including ZnO, SnO2, and NiO that exhibit exceptional electrochemical properties as negative electrodes for LIBs.

The simple synthetic route comprised of electrospinning and calcination processes enables to form porous one-dimensional 1D structured ZSO, which is the atomic combination between ZnO and SnO2, exhibiting effective strain relaxation during battery operation. Furthermore, the catalytic effect of Ni converted from the surface-functional NiO nanolayer on ZSO significantly contributes to improved reversible capacity.
