A novel hybrid nanocarbon consisting of one rippled and two planar nanosheets has been synthesized and characterized. Two meso pairs of [5]helicenes are formed along the long molecular axis of the hybrid to connect rippled and planar subunits, leading to a stable conformation. It is shown that the hybrid possesses the individual electronic properties of the rippled and planar subunits. Compared to the rippled subunit, such hybrid has a better geometric match to C 60 and complexes with C 60 in a 1 : 1 stoichiometry, with the association constant on the order of 10 5 M −1 . The hybrid displays unusual anti -Kasha fluorescence emission. The transient absorption spectroscopy revealed that the singlet fission (SF) from higher level singlet excited states (S n ) is operative in the film of the hybrid.

Vanadium pentoxide (V2O5) stands out as a preferred cathode material for stretchable lithium-ion batteries due to its high specific capacity, robust structural stability, cost-effectiveness, and ease of synthesis. However, its practical application is limited by a low Li+ diffusion coefficient (10−12–10−13 cm2 s−1) and poor electrical conductivity. To address these challenges, we have developed an innovative yolk-shell V2O5 architecture using a facile synthesis method involving spray pyrolysis followed by thermal treatment. This yolk-shell V2O5 is coated with a poly(ethylene oxide) (PEO) electrolyte to enhance ion transport contact areas and flexibility. The yolk-shell V2O5@PEO is then integrated with a PEO-based polymer electrolyte in a thin film configuration, paired with zig-zag truncated lithium metal anodes for stretchable lithium metal batteries. The integrated film demonstrates superior electrochemical performance due to highly reversible Li+ insertion/extraction and enhanced Li ion diffusion. The unique design of the stretchable Li-yolk-shell V2O5@PEO battery achieves an excellent specific discharge capacity of 261 mAh g−1, compared to 158 mAh g−1 for pure V2O5 at 0.1C. Additionally, the stretchable Li-yolk-shell V2O5@PEO cell exhibits a discharge capacity of 250 mAh g−1 under zero-strain conditions and 233.7 mAh g−1 under 40 % strain at 0.1C and 40 °C. Characterization through X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirms the nano-sized morphology and high crystallinity of the yolk-shell V2O5. X-ray photoelectron spectroscopy (XPS) analysis reveals the transformation of yolk-shell V2O5@PEO into α-V2O5, Ε-Li0.5V2O5, δ-LiV2O5, and γ-Li2V2O5 phases during lithium-ion (de)intercalation. This cutting-edge battery design paves the way for the development of high-performance, stretchable, and flexible batteries, ideal for next-generation portable electronic devices. © 2024 Elsevier Ltd

Benefiting from unique properties including faster mass transfer, more exposed active sites and large molecule recognition, hierarchically porous metal-organic frameworks (HP-MOFs), in the form of ultrasmall nanoparticles (NPs) and having self-assembled interparticle mesopores, have garnered greater attention in recent years that given to typical MOFs. However, the controllable synthesis of HP-MOFs on the nanoscale remains a significant challenge. Herein, we describe the results of a study that led to the development of the first, facile top-down acid etching method for preparing the nanosized (~15 nm) mesoporous MOF, HP-UiO-66-NH2(Hf). The sizes of mesopores in this material can be effectively tuned by simply controlling the concentration of propionic acid (PA) utilized in the preparation solution. Remarkably, the mesoporous structure of HP-UiO-66-NH2(Hf) exhibits excellent chemical stability under acid/base conditions and it can be readily constructed by using at least 4 times recycled PA etching solution. In addition, HP-UiO-66-NH2(Hf) displays high size-selectivity for adsorption of enzymes. Moreover, the nanocomposite generated by complexation with glucose oxidase (GOD), GOD@HP-UiO-66-NH2(Hf) has a higher catalytic activity and a significantly enhanced stability (recycled for at least 7 times) in promoting oxidation of glucose compared to its MOF counterpart, GOD@UiO-66-NH2(Hf) and native GOD. This study provides a potentially general strategy to design and construct stable nanosized HP-MOFs which have applications to large molecule encapsulation and catalysis. © 2022, The Authors.

Batteries are the most widely used energy storage devices, and the lithiumion battery is the most heavily commercialized and most widely used battery type in the industry. However, the current rapid development of society requires a major advancement in battery materials to achieve high capacity,long life cycle, low cost, and reliable safety. Therefore, many new efficient energy storage materials and battery systems are being developed and explored, and their working mechanisms must be clearly understood before industrial application. In recent years, density functional theory (DFT) has been employed in the energy storage field and has made significant contributions to the understanding of electrochemical reaction mechanisms and to virtual screening of promising energy storage materials. In this review,the applications of DFT to battery materials are summarized and exemplified by some representative and up-to-date studies in the literature. The main focuses in this review include the following:1) structural stability estimation by cohesive energy, formation energy, Gibbs free energy, and phonon dispersion spectra calculations;2) the Gibbs free energy calculations for electrochemical reactions, corresponding open-circuit voltage, and theoretical capacity predictions of batteries;3) the analyses of molecule orbitals, band structures, density of states (DOS), and charge distribution of battery materials;4) ion transport kinetics in battery materials;5) simulations of adsorption processes. We conclude the review with the discussion of the assessments and validation of the popular functionals against several benchmarks, and a few suggestions have been given for the selection of density functionals for battery material systems.

The oxygen evolution reaction (OER), as a four-electron transfer process with large overpotential loss that is also kinetically sluggish, is one of the most crucial electrochemical processes to convert renewable energy into chemical fuels. Ruthenium (Ru)-based electrocatalysts for the OER have several advantageous features including high activity, pH-universality and the lowest price in the noble metal family. However, the instability of Ru-based catalysts in the OER is a central hurdle limiting their widespread application. This review focuses on recent developments made in the field of Ru-based OER catalysts. In the coverage, first the characteristics of Ru-based OER catalysts such as the OER mechanism, intrinsic activity and stability issue are discussed. Then, recently reported Ru-related catalysts falling in the Ru metal and Ru compound subclasses are described with special emphasis being given to a discussion of activity/stability-enhancing strategies. Finally, several challenges and future perspectives in this field are summarized. It is anticipated that this review will promote a better understanding of Ru-based OER catalysts and lead to new strategies to design active and stable Ru-materials.

The intrinsic ferroelectricity and related dielectric properties of M-type Barium Hexaferrite (BaFe12O19) with excellent magnetic performance are reported in this paper. A classic electric polarization (P-E) hysteresis loop with full saturation, together with two nonlinear reversal current peaks in the I-V curve and huge change of dielectric constant in the vicinity of Curie temperature, have all demonstrated themselves as sufficient experimental evidences to verify the ferroelectricity of BaFe12O19 ceramics. It holds a large remnant polarization at 108 μC/cm2 and a suitable coercive field at 117 kV/cm. Two peaks at 194°C and 451°C in the temperature-dependent dielectric spectrum of BaFe12O19 ceramics are considered to be the phase transition from ferro- to antiferro- and antiferro- to para-electric structures. A conventional strong magnetic hysteresis loop was also observed. The magnetically induced polarization upon the BaFe12O19 ceramics was achieved in the form of alternating spin current waves. A ME-coupling voltage with an amplitude of ±23mV on an applied magnetic field at 500mT was achieved. These combined multiple functional responses of large ferroelectrics and strong ferromagnetism reveal the excellent multiferroic features of BaFe12O19, which would bring forth the great opportunity to create novel electric devices with active coupling effect between magnetic and electric orders.
