Service Providers' Perceptions of Psychological, Emotional, and Behavioral Issues Among Children and Adolescents During COVID‐19 in South Korea

ABSTRACTVarious emotional and psychological support services for children and adolescents were implemented in South Korea during the COVID‐19 era. However, little is known about the limitations and future directions of current support services from the perspective of service providers. The purpose of this study was to explore service providers' perspectives on emotional and psychological support services for children and adolescents. The present study purposively recruited 11 clinical practitioners providing support services for children and adolescents to conduct semistructured focus group interviews. Thematic analysis identified four major themes: (a) a noticeable increase in problematic behaviors among children and adolescents (e.g., intrinsic and extrinsic problem behaviors); (b) changes in service use patterns (e.g., increased non‐face‐to‐face services); (c) frustrations with inadequate support systems (e.g., the absence of qualified professionals); and (d) identifying future directions (e.g., improving awareness of support services). The findings highlight the necessity of enhancing awareness of how to access services by reducing stigma. The findings also emphasize the need for improved cooperation between public and private facilities, as well as a greater number of skilled professionals to provide high‐quality programs. The practical and political implications are discussed based on the findings.

Public image of nursing in modern society: An evolving concept analysis.

This study aimed to analyse the evolution of the public image of nursing in the context of the constantly developing nursing profession. The Rodger's evolving concept analysis was applied. PubMed, CINAHL, Web of Science, Scopus, and ProQuest databases were searched for articles published between 1 January 2001, and 30 April 2022, using the search terms; "NURS * AND image". The selected literature was screened using Rodgers' evolutionary method to explore the attributes, antecedents and consequences of the concept. The defining attributes were identified as nursing (nursing as the collective object), public (public as the collective subject) and information (the medium of interaction between the collective subject and the collective object). Nursing elements were classified into intrinsic elements (professional spirit, professional knowledge and professional skills) and extrinsic (appearance, language and behaviour) elements. Public elements were further subcategorized into public categories (internal organizational public and external organizational public) and public perceptions (cognition, emotion and behavioural intention). The information elements are mainly classified as information generation, dissemination, identification, processing and judgement. The antecedents and consequences of the public perception of nursing were also identified. The public image of nursing is dynamic and has evolved over time. Its dynamism and malleability imply that the traditional public image of nursing can be improved through targeted interventions in nursing practice, management and education. Identifying the antecedents and consequences associated with the public image of nursing will help the healthcare organizations adopt effective strategies to alleviate the shortage of the nursing workforce and promote the development of the nursing profession.

Effective rare-earth doping on semiconductor behavior for BaTiO3-based automotive MLCCs

Highly accelerated lifetime test (HALT) for lifetime evaluation was performed on the state-of-art automotive MLCC prototypes by varying Dy/Mg (donor/acceptor) ratio added to BaTiO3. The results clearly showed that the mean time to failure (MTTF) more than 280 times as the Dy/Mg ratio increased from 1.0 to 10.0. Since oxygen vacancies typically form in-gap state/defect at the donor level, the activation energy value under thermal activation process as a function of voltage was calculated and compared by non-destructive testing (I–V curve) for an accurate evaluation of the extrinsic behavior. It was found that barrier height at the Ni/BT interface decreases as the voltage increases, resulting in a decrease in activation energy. As the Dy/Mg ratio increases, the density of defects/in-gap states formed at the donor level in the bandgap by oxygen vacancies decreases, which may lead to a decrease in the number of electrons excited by the external voltage. Furthermore, it was verified that the calculated Schottky barrier height of the 10.0 Dy/Mg ratio under voltage has higher value than that of the 2.6 Dy/Mg ratio. Based on the results of this study, we propose a new indicator for the design of automotive MLCCs with high lifetime reliability that can be used for comparative analysis of additive compositions through non-destructive test (I–V curve) with low evaluation time/cost.

Demonstration of extrinsic chirality in self-assembled asymmetric plasmonic metasurfaces and nanohole arrays

Chirality, the lack of mirror symmetry, can be mimicked in nanophotonics and plasmonics by breaking the symmetry in light-nanostructure interaction. Here we report on versatile use of nanosphere lithography for the fabrication of low-cost metasurfaces, which exhibit broadband handedness- and angle-dependent extinction in the near-infrared range, thus offering extrinsic chiro-optical behavior. We measure wavelength and angle dependence of the extinction for four samples. Two samples are made of polystyrene nanospheres asymmetrically covered by silver and gold in one case and silver only in the other case, with a nanohole array at the bottom. The other two samples are nanohole arrays, obtained after the nanosphere removal from the first two samples. Rich extrinsic chiral features are governed by different chiro-optical mechanisms in the three-dimensional plasmonic semi-shells and planar nanohole arrays. We also measure Stokes parameters in the same wavelength and incidence angle range and show that the transmitted fields follow the extrinsic chirality features of the extinction dissymmetry. We further study the influences of the nanostructured shapes and in-plane orientations on the intrinsic vs extrinsic chirality. The nanoholes are modelled as oval shapes in metal, showing good agreement with the experiments. We thus confirm that nanosphere lithography can provide different geometries for chiral light manipulation at the nanoscale, with the possibility to extend functionalities with optimized oval shapes and combination of constituent metals.

Intrinsic pseudocapacitive enhancement of NiCo2O4/activated carbon composites for high-performance supercapacitors

The high electrical conductivity and capacitance of NiCo2O4 have made it a promising electrode material for supercapacitors with advantages in rapid energy storage, long cycle life, and potential for flexible applications. Nickel Cobaltite Oxide (NiCo2O4) nanoflakes were successfully synthesized by the sol–gel method. The composite Activated carbon was made from waste coconut shells. The X-Ray Diffraction (XRD) pattern matches with the standard values, the crystallite sizes were found to be 7 nm using the Debye Scherrer formula. FTIR reveals the molecular bond of (NiCo2O4) NFs and their composites peak at 541 cm−1 and 552 cm−1 confirms the formation of NiCo2O4 Metal oxides. From optical absorption studies, it is found that both NiCo2O4 NFS and NiCo2O4/AC composites have maximum absorption throughout the UV region. The bandgap increases from 1.26 eV to 1.34 eV on adding AC composites to NiCo2O4 NFs. Scanning Electron microscopy (SEM) shows the formation of NiCo2O4 nanoflakes. The activated carbon has high surface area with micropores, confirmed by BET analysis. Cyclic Voltammetry (CV) analysis shows that NiCo2O4/AC composite has a more specific capacitance at low scan rate of 10 mV/s, which is more than NiCo2O4 NFs. Both the samples recorded high specific capacitance values of 142 F g−1 and 192 F g−1 at the current density of 1 A/g using GCD. From this NiCo2O4/AC composites may be a high-performing capacitor with intrinsic pseudocapacitive behaviour compared to NiCo2O4 NFs which has extrinsic pseudocapacitive behaviour.

Cell-type-specific optogenetic fMRI on basal forebrain reveals functional network basis of behavioral preference

The basal forebrain (BF) is a complex structure that plays key roles in regulating various brain functions. However, it remains unclear how cholinergic and non-cholinergic BF neurons modulate large-scale functional networks and their relevance in intrinsic and extrinsic behaviors. With an optimized awake mouse optogenetic fMRI approach, we revealed that optogenetic stimulation of four BF neuron types evoked distinct cell-type-specific whole-brain BOLD activations, which could be attributed to BF-originated low-dimensional structural networks. Additionally, optogenetic activation of VGLUT2, ChAT, and PV neurons in the BF modulated the preference for locomotion, exploration, and grooming, respectively. Furthermore, we uncovered the functional network basis of the above BF-modulated behavioral preference through a decoding model linking the BF-modulated BOLD activation, low-dimensional structural networks, and behavioral preference. To summarize, we decoded the functional network basis of differential behavioral preferences with cell-type-specific optogenetic fMRI on the BF and provided an avenue for investigating mouse behaviors from a whole-brain view.

Kinematics modeling of the gear-based crank mechanism engine regardless of the compressions ratio variations.

In this work, geometric and kinematic modeling of the gear-based crank mechanism engine (GBCM) was performed. To this aim, a mechanical approach based on projective computational methods and mechanism theory laws is applied, to which a parametric study has allowed a conclusion on the geometrical and kinematic behaviors of the moving links. The study concluded that the kinematic quantities at connecting rod head are one-half of those at the piston top head. The extrinsic behavior like the stroke of the connecting rod head is twice the crank radius and the piston kinematic are identical to the conventional engine with the same crankshaft ratio regardless of the compression ratio and any gear wheel radius. Hence, all the extrinsic kinematic properties of a classic crankshaft mechanism of the fixed compression ratio engine remain valid for a gear-based crank mechanism engine and can be used for dynamic calculation purposes.

Extrinsic chirality tailors Stokes parameters in simple asymmetric metasurfaces.

Metasurfaces tailor electromagnetic confinement at the nanoscale and can be appropriately designed for polarization-dependent light-matter interactions. Adding the asymmetry degree to the desing allows for circular polarizations of opposite handedness to be differently absorbed or emitted, which is of interest in fields spanning from chiral sensing to flat optics. Here, we show that simple, low-cost asymmetric metasurfaces can control Stokes parameters in the transmitted far-field. With only 50 nm of asymmetric plasmonic shells on self-assembled polystyrene nanospheres, our metasurfaces allow for great spectral and incident angle tunability. We first investigated broadband extrinsic chirality in metasurfaces with asymmetric plasmonic semishells; we found high extinction circular dichroism (CD) in the near-infrared range. We then excited it with linear polarization and performed hyperspectral Stokes polarimetry on the transmitted field. We showed that the S3 parameter follows the behavior of CD in extinction, and that the output field position on the Poincaré sphere can be widely controlled by using the incidence angle and wavelength. Furthermore, simulations agreed well with the experiments and showed how the near-field chiro-optical response influences the extrinsic chiral behavior in absorption and the polarization state of the transmitted field.

Firstly, it was found that the mother's parenting attitude and the young children's emotional regulation ability were correlated with the young children's problem behavior. Secondly, in the relative explanatory power of independent variables that affect young children's intrinsic problem behaviors, negative emotional expression, affectionate, controlling, and rejecting influences in the order shown. In the relative explanatory power of independent variables that affect extrinsic problem behaviors of young children, affectionate, negative emotional expression, controlling, and positive emotional expression were found to have an effect in the order.
 Conclusions This study provides valuable information on the variables affecting young children's problem behaviors, such as maternal parenting attitudes and young children's emotion regulation abilities. It can serve as foundational data to enhance maternal parenting attitudes and young children's emotion regulation abilities, which, in turn, may help improve young children's problem behaviors.

Perspective on defect control in semiconductors for photovoltaics

Harnessing the boundless solar energy, photovoltaic cells emerge as pivotal players in the world’s sustainable energy landscape. The efficiency of solar cells is intimately tied to the carrier properties influenced by defects and impurities within the sunlight-absorbing semiconductors. In this Perspective, we offer a brief overview of recent advances in exploring doping properties with a focus on three vital thin-film photovoltaic semiconductors: CdTe, CIGS, and halide perovskites. Our discourse encompasses their electronic band structure, intrinsic and extrinsic doping behaviors, defect-assisted nonradiative recombination losses, as well as promising strategies poised to enhance solar cell efficiency. Additionally, we discuss several lingering challenges associated with defects in the advancement of photovoltaic technologies.

Emerging criticality: Unraveling shifting dynamics of the EU's critical raw materials and their implications on Canada and South Africa

Critical Raw Materials (or CRMs) are materials that are in high demand, difficult to replace and whose supply is prone to disruption. Various nations have defined CRM lists, although terminology, supporting data and assessment frameworks differ. The European Union (EU) has the longest published history of CRM lists with the first one published in 2011, followed by 3-year revisions. In this study, we analyze CRM designation trends over time by using the EU's five CRM lists to deduce the driving factors. Overall, the number of CRMs have increased by 1.67 new CRMs per year from 2011 to 2023, with the number of new CRMs yet to reach a plateau. Our analysis also reveals issues that could affect the value of the CRM lists including: (1) a hidden two-stage process with transparency issues; (2) static baselines with regards to criticality; (3) an overemphasis on ideology versus pragmatism; (4) a lack of differentiation between CRMs and strategic raw materials (SRMs); (5) a lack of foresight; and (6) a lack of consideration for extrinsic risks and system behaviour. Given these issues, we provide suggestions to improve the CRM assessment methodology and discuss the implications for the EU and the minerals industry. Subsequently, we extend our findings to Canada and South Africa, which are nations in the early stages of CRM framework creation. We find that Canada has more time to realize its CRM framework as compared to the EU, and that South Africa may be faced with a bifurcating reality of extra-national and national needs. Our findings also highlight serious geopolitical implications with the ensuing competition for resources likely resulting in the formation of economic blocs, clubs or cartels. Finally, improvements to the methodology resulting in more predictable outcomes would better incentivize the minerals industry to lower investment risk and ensure a smooth and pragmatic green energy transition.

Domain wall motion across microstructural features in polycrystalline ferroelectric films

This paper describes the effect of microstructural features such as grain boundaries and triple points on the pinning of domain wall motion in perovskite Pb(Zr0.52Ti0.48)O3 (PZT) films on polycrystalline SrRuO3/SrTiO3 substrates. Spatial variability in the collective domain wall dynamics was assessed using non-linearity mapping via Band Excitation Piezoresponse Force Microscopy (BE-PFM). Collocating the non-linearity maps with triple point locations (as visualized by EBSD) allowed for exploration of the effects that local microstructure (e.g., grain boundary) have on domain wall motion. It was found that the extrinsic behavior varied with both the misorientation angle and the proximity to the grain boundary. The width of influence of individual grain boundaries on the motion of domain walls was a function of the character of the grain boundary; random grain boundaries exhibit deeper minima in αd/d33,initial and larger widths of influence (up to 905 nm) compared to coincident site lattice (CSL) boundaries (up to 572 nm). Additionally, triple points containing larger numbers of random boundaries exhibited non-Rayleigh behavior to greater distances, suggesting that the triple point provides either a deep potential minimum or a region where domain wall motion is unfavorable.

Extrinsic chirality in metasurfaces: Traditional and unconventional experiments – INVITED

Plasmonic nanostructures with achiral, but asymmetric shapes can exhibit chiro-optical phenomena at the nanoscale, given that the nanostructure-light interaction symmetry is broken. Such behaviour is defined as extrinsic chirality, and it is induced by properly arranging the experimental set-up. We show measurement techniques for extrinsic chirality in low-cost, asymmetric samples with nanostructures organized in metasurfaces. We employ widely tuneable chiro-optical characterization of transmission and reflection, as well as the circular polarization degree of the transmitted signal; near-infrared range (680-1080nm) and oblique incidence allow for the detection of resonant features in extrinsic chirality. Other, unconventional experiments use photo-thermal consequences of chirality governed absorption in metasurfaces. Photo-acoustic spectroscopy directly gives circular dichroism as a differential absorption of the left and right circular polarizations exciting the sample. Photo-deflection spectroscopy gives additional information of diffraction phenomena governed by the extrinsic chirality. We showed that these techniques can monitor the extrinsic chiral behaviour of the hybrid plasmonic metamaterials. Moreover, they can be used in combination with fluorescence-detected circular dichroism to measure the emission properties of fluorescent materials.

Deoxyribonucleic acid scaffold assisted structural engineering to tune the intrinsic to extrinsic capacitive behavior in spinel structured MnCo2O4.5 for high-performance asymmetric supercapacitor application

The spinel structured materials (e.g., MnCo2O4.5) are good aspirants for supercapacitor electrode application due to their outstanding pseudocapacitor performance. However, due to the collapsing of the crystal and morphological structures during electrochemical analysis, inferior cyclic stability and low energy density problems are inevitable when the materials are used as supercapacitor electrodes. Alteration of intrinsic (diffusion-controlled) to extrinsic (surface-controlled) capacitive behavior is the effective solution to overcome these issues. Herein, the intrinsic capacitor behavior of the MnCo2O4.5 material was altered into an extrinsic mechanism through the precipitation process with the aid of a deoxyribonucleic acid (DNA)-based structural engineering process. The MnCo2O4.5 coated on nickel foam current collector delivered the specific capacity of 649C g−1 at 1 A g−1 and retained 97 % of its initial capacity after 5000 cycles at 20 A g−1 in three-electrode configurations. Additionally, the MnCo2O4.5//Activated carbon asymmetric device showed a specific capacity of 93.8C g−1 at 1 A g−1 with energy and power densities of 33.4 Wh Kg−1 and 681 W Kg−1 at 1 A g−1, respectively. DNA-based structural engineering demonstrates the tuning of intrinsic to extrinsic capacitive behavior resulting in better supercapacitor properties in MnCo2O4.5 material.

High Electrochemical Performance of a Nanostructured Electrode Material Based on a Cobalt-Manganese Layered Double Hydroxide

In this work, alpha-cobalt hydroxide (Co(OH)2) and cobalt/manganese layered double hydroxide (CoMn-75-LDH) were synthesized using the Tower method. The alpha phase was confirmed for Co(OH)2 through XRD analysis. Furthermore, the TEM images showed that the materials are formed by nanoparticles with an average size of ~5 nm. Cyclic voltammetry and galvanostatic charge/discharge measurements were carried out and the CoMn-75-LDH presented a superior electrochemical behavior to Co(OH)2. The presence of Mn2+/3+ ions in the crystal structure of CoMn-75-LDH, verified by XPS analysis, enhanced the electrical conductivity of the material, providing more electroactive sites, as a result, the electrochemical performance of the material was improved. Electrochemical studies showed that CoMn-75-LDH has a specific capacitance of 677 F g-1 at current density of 0.5 A g-1 compared to Co(OH)2, whose specific capacitance value was 268.7 F g-1 at the same current density. In addition, the electrochemical signature of Co(OH)2 revealed that the electrode material exhibits an extrinsic pseudocapacitive behavior instead of the typical behavior of battery-type materials due to its nanostructured morphology. Also, electrochemical studies showed that the charge storage mechanism for CoMn-75-LDH is controlled by both the capacitive and diffusion process.

The Effects of White Noise on Attentional Performance and On-Task Behaviors in Preschoolers with ADHD.

Several models have tentatively associated improving attention-deficit/hyperactivity disorder (ADHD) symptoms with arousal and external environmental stimulation. In order to further clarify the relationships between ADHD symptoms, arousal, and external stimulation, this study focused on exploring the "simultaneous" effects of white noise on intrinsic attentional performance and extrinsic on-task behaviors in preschoolers with and without ADHD. By using the computerized task (K-CPT 2), 104 preschoolers, including 52 ADHD children and 52 typically developing (TD) children, were tested and analyzed for their intrinsic attention (such as detectability, omission errors, commission errors, and reaction time). Simultaneously, these preschoolers' external on-task behaviors were recorded for analysis through systematic observation. This study showed that white noise could effectively improve attention performance, including enhancing the ability to differentiate non-targets from targets and decreasing omission errors. It could also reduce the extrinsic hyperactive behaviors of preschoolers with ADHD. The findings of this study highlighted that white noise stimulation is a beneficial non-pharmacological treatment for preschoolers with ADHD. In contrast, for TD preschoolers, the results of this study showed that the external white noise stimuli were not only unhelpful but also a burden.

Phase-Dependent Energy Storage Performance of the NixSey Polymorphs for Supercapacitor-Battery Hybrid Devices.

Transition-metal chalcogenides have emerged as a promising class of materials for energy storage applications due to their earth abundance, high theoretical capacity, and high electrical conductivity. Herein, we introduce a facile and one-pot electrodeposition method to prepare high-performance nickel selenide NixSey (0.5 ≤ x/y ≤ 1.5) nanostructures (specific capacity = 180.3 mA h g-1 at 1 A g-1). The as-synthesized nickel selenide (NS) nanostructure is however converted to other polymorphs of nickel selenide including orthorhombic NiSe2, trigonal Ni3Se2, hexagonal NiSe, and orthorhombic Ni6Se5 over cycling. Interestingly, NiSe2 and Ni3Se2 polymorphs that display a more metallic character and superior energy storage performance are the predominant phases after a few hundred cycles. We fabricated a hybrid device using activated carbon (AC) as a supercapacitor-type negative electrode and NS as a high-rate battery-type positive electrode (AC||NS). This hybrid device provides a high specific energy of 71 W h kg-1, an excellent specific power of up to 31 400 W kg-1, and exceptional cycling stability (80% retention of the initial capacity after 20 000 cycles). The higher energy storage performance of the device is a result of the development of high-performance NiSe2 and Ni3Se2 polymorphs. Moreover, the reduction of the critical dimension of the NS particles to the nanoscale partially induces an extrinsic pseudocapacitive behavior that improves the rate capability and durability of the device. We also explored the origin of the superior energy storage performance of the NS polymorphs using density functional theory calculations in terms of the computed density of states around the Fermi level, electrical conductivity, and quantum capacitance that follows the trend NiSe2 > Ni3Se2 > NiSe > Ni6Se5. The present study thus provides an appealing approach for tailoring the phase composition of NS as an alternative to the commonly used templated synthesis methods.

Structural, electrical and gas sensing functionality of fabricated Co1-xZnxFe2-xNixO4 (x= 0.0,0.3) nanoparticles

This article reports for the first time the structural, electrical, and gas sensing functionality of novel composition of spinel-type porous Co0.7Zn0.3Fe1.7Ni0.3O4 microspheres fabricated through a simple hydrothermal route. The structural, morphological, and elemental properties of the materials are characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) along with selected area electron diffraction pattern. XRD and XPS data reveal a pure phase spinel-type cubic crystal formation. Electron microscopic investigations confirm that the microspheres are devloped by the porous nano-lamellae made up of nanoparticles that are interconnected in a manner to form highly stable porous microspheres. AC impedance spectroscopy is utilized to analyse the electrical conductivity at different temperatures which disclose extrinsic semiconductor behaviour. The DC conductivity derived activation energy of the sample is found to be 0.76 eV. The frequency dependent conductivity of the compound obeyed Jonscher's power law and Koop's phenomenological theory. The sensing properties of the Zn and Ni doped ferrite were investigated for different gases and it demonstrates the promising sensing behaviour towards butane gas.

Creation of an extrinsic pseudocapacitive material presenting extraordinary cycling-life with the battery-type material Co(OH)2 by S2− doping for application in supercapacitors

Some battery-type materials show the potential for storing high density energy in supercapacitors because of their high theoretical capacity. So far, the very unsatisfied electrochemical performance is still the label of these battery-type materials, which is attributed to their diffusion-controlled kinetics of energy storage. Some efforts try to transform their electrochemical behavior to extrinsic pseudocapacitive behavior through nanostructuring. However, the extrinsic pseudocapacitive materials are rare due to the restriction of no phase transformation. In this work, we propose an alternative strategy to create an extrinsic pseudocapacitive material from the typical battery-type material Co(OH)2 by S2− doping. The doped S2− ions further increase energybarrierfor the intercalation of OH− ions into the interlayer space of Co(OH)2, thus suppressing its bulk phase transformation. Also, the decreased OH− ions-Co(OH)2 interaction plus the surface reaction feature induced by S2− doping results in the pseudocapacitive behavior. Thus, the S2− doped Co(OH)2 presents the comprehensive electrochemical signatures of pseudocapacitive materials and an extraordinary cycling life of 200,000 charge-discharge cycles. This work initiates a new way for acquiring electrode materials with high electrochemical performance for application in supercapacitors.

Nanometric Amorphous TiO2 As an Extrinsic Pseudo-Capacitive Electrode for All-Solid-State Asymmetric Hybrid Micro-Supercapacitors: Effects on the Electrochemical Performance

On-chip solid-state micro-supercapacitors (MSCs) have gained widespread attention owing to their versatile benefits, including high power density and long cycle life1,2. Recently asymmetric hybrid microsupercapacitors (AsHMSCs) introducing a charge storage mechanism based on both faradaic reaction and electric double-layer phenomena have been considered to increase the energy density. Within this context, the selection of electrode materials and their interaction at the interface with the electrolyte is a key issue to optimize the AsHMSC electrochemical performance.In this work, nanometric (5-20 nm thick) amorphous TiO2 films have been elaborated and characterized in liquid and solid-state electrolyte (LiPON) half-cell configurations. Interestingly, TiO2 films after LiPON deposition exhibited a constant initial amount of intercalated lithium ions for all considered thicknesses and did not require a first activation process, in comparison to the liquid electrolyte configuration. For all considered configurations, the specific capacity extracted from cyclic voltammetry and galvanostatic cycling within [0.5-3V] potential range correspond to the theoretical value expected for the Lix=1TiO2 phase at low current density. Furthermore, the cooperative effects of high Li ion intercalation kinetics and Low interfacial charge transfer resistance for 5nm TiO2 electrode (extracted from electrochemical impedance spectroscopy analysis) exhibit an outstanding specific capacity of 2mC.cm-2 at 1µA.cm-2, and high rate performance with 60% capacity holding ratio at 100µA.cm-2, thus highlighting the extrinsic pseudo-capacitive behavior of the sub 10nm electrodes.A TiO2 5nm/LiPON 100nm/Pt AsHMSC is successfully fabricated, which achieves an operating voltage window of 3V and a specific capacity of 0.3mC.cm-2 at 1mA.cm-2.In addition, the device also exhibited a 100% coulombic efficiency even after cycling for 6000 continuous charge-discharge cycles. This work offers an approach to tune the Li ion storage properties of TiO2 by nano-engineering and gives insights into the enhancement of pseudocapacitance-assisted lithium-storage capacity.References Kyeremateng et al., Nature Nanotech 12, 7–15 (2017). https://doi.org/10.1038/nnano.2016.196Sallaz et al., J.
