The avian tail plays a critical role in enhancing aerodynamics as well as flight control. In this study, high-speed 3D kinematic tracking of a lovebird (Agapornis roseicollis) was employed to capture detailed tail dynamics during maneuvering flight. A pronounced, time-varying spanwise bending behavior was observed to synchronize with wingbeat cycles and tail-spreading maneuvers. To evaluate the implications of this behavior, we developed a biomimetic robotic tail and conducted systematic wind tunnel experiments combining force measurements and Time-Resolved Particle Image Velocimetry (TR-PIV). The PIV measurements elucidate that the spanwise bending causes vorticity to move from the central region toward the outside edges, which can substantially influence the aerodynamic forces and moments. Together with wing motion and variations in surface area, tail bending provides an additional aerodynamic mechanism for avian flight control.
The design of soft actuators remotely controlled by optical triggering and propelling schemes requires materials that might combine ease of device fabrication and miniaturization with robust performance of moving parts and versatile and precise response to light stimuli. Here, light-triggered photochromic-doped poly(methyl methacrylate)/reduced graphene-oxide bilayers are proposed as effective actuation architectures, showing multi-photoaddressable bending and distinctive photothermal properties. By interlayer thermomechanical contrast and intrinsic mechanical amplification of photoinduced strain mismatch, these hybrid systems show good bending and load-lifting performance, broadband photothermal triggering, as well as faster thermal and actuation response compared to pristine photochromic films. Under UV illumination, measured displacements, exerted force, and response time reach values of about 200 μm, 2 mN, and the scale of few seconds, respectively. The photothermal conversion efficiency of the system is estimated to be at least 55%. Such properties make these architectures appealing as actuation elements for various device platforms, including segments of biomimetic components, and biomedical devices with precise structure-function design of the optical control.
Healthcare professionals (HCPs) in cancer care face increasing challenges with demand for care outpacing workforce growth. Professional demands contribute to decreases in job satisfaction and increases in experiences of burnout, which have serious implications for patient care and staff wellbeing. It is, therefore, important to determine factors that may buffer against burnout. This study focused on psychological inflexibility and resilience as psychological characteristics that may predict dimensions of burnout and support professional fulfilment. We administered an anonymous self-report survey to HCPs in Ireland through professional networks. Structural Equation Modelling assessed how gender, career stage, resilience and psychological inflexibility related to dimensions of burnout and professional fulfilment among 179 cancer care HCPs in Ireland. Psychological inflexibility predicted higher emotional exhaustion and depersonalization, while resilience predicted lower professional inefficacy and higher professional fulfilment. Women reported higher emotional exhaustion and lower professional fulfilment. Early career HCPs showed higher depersonalization. Our findings demonstrate a relationship between psychological inflexibility, resilience and key markers of personal and professional wellbeing. This suggests a potential pathway for comprehensive intervention; while waiting for adequate systemic change, promoting greater resilience and psychological flexibility may support cancer care HCPs in the workplace.
Hybrid structures, formed by joining organic and inorganic semiconductors, can harness the unique photophysical properties of each material to achieve new functionality. In these hybrid systems, the interface between disparate materials must be carefully structured to dictate the properties of the whole. When exciton transfer between materials is the goal, the interface must be crafted to promote electronic coupling between the energy-donating and -accepting layers. Here, we study how covalent attachment of anthracene to a Si(111) surface influences the molecular and electronic structure of the molecule-solid interface. Using a combination of density functional theory (DFT) geometry optimizations and Born-Oppenheimer molecular dynamics (BOMD), we find anthracene molecules twist and distort after bonding to the silicon surface, lowering their symmetry and widening their HOMO-LUMO gap by approximately 160 meV. Electronic sum frequency generation (ESFG) measurements of anthracene-functionalized Si(111) surfaces identify anthracene-associated electronic resonances that are blue-shifted relative to the linear absorption features of anthracene in solution, supporting the predictions. These findings highlight the critical role of molecular distortion in tuning electronic properties at hybrid interfaces, offering insight into the design of functional organic/inorganic materials for optoelectronic applications.
Flexible all-perovskite tandem solar cells (PTSCs) are promising for lightweight photovoltaics, yet their mechanical degradation under bending remains poorly understood. Although bending instability has often been attributed to brittle fractures, halide perovskites are mechanically soft materials. Here, we demonstrate that bending-induced degradation in flexible PTSCs primarily associated with strain-induced evolution of residual-stress accumulation prior to crack formation, while elastic-modulus engineering through grain-boundary polymerization mitigates this mechanically induced degradation. Grazing-incidence X-ray diffraction analyses reveal that repeated bending accumulates residual stress of both wide-bandgap and narrow-bandgap perovskite layers in PTSCs, leading to fatigue-associated degradation and enhanced nonradiative recombination even in the absence of visible cracks. To address this intrinsic limitation, a dual-layer grain-boundary in situ polymerization strategy is introduced for both perovskite layers, enabling elastic relaxation and suppressing residual-stress accumulation. As a result, flexible PTSCs achieve a power conversion efficiency of 24.97% and retain over 90% of their initial efficiency after 5000 bending cycles at a radius of 5 mm. This work establishes elastic-modulus engineering as a key design principle for mechanically robust flexible perovskite tandem solar cells.
Venous thrombosis is influenced by Virchow's triad, and a decrease in venous velocity is considered one of the risk factors. In this study, we examined three foot and leg movements-bending the ankle back and forth ("Bending"), squeezing the toes ("Squeezing"), and massaging and milking the calf ("Milking")-using healthy volunteers and ultrasound to determine which exercise increased venous velocity the most. The results showed that "Bending" produced the highest velocity, while "Squeezing" produced the lowest. We also compared left and right sides for each exercise, finding that left-side velocity during "Milking" was significantly lower than the right side.
Complex craniocervical malformations pose significant challenges to surgical fixation. The biomechanical advantage of occipital plate fixation versus short-lever modified C1 lateral mass screw fixation remains controversial, and finite element analysis (FEA) is a reliable tool for implant performance evaluation. To compare biomechanical characteristics of occipital plate fixation and modified C1 lateral mass screw fixation in AOZ-BI and AOZ-AAD models via FEA, and guide surgical decision-making. A validated healthy occipito-atlantoaxial (C0-C2) FEA model was established using CT data. Two pathological models were constructed: AOZ-BI (Group A, atlantoaxial distance [ADI] < 5 mm) and AOZ-AAD (Group B, ADI ≥ 5 mm with transverse ligament dysfunction), each divided into occipital plate and modified C1 lateral mass screw subgroups. Static loads (40 N preload + 1.5 N·m torque) simulated flexion (Fe), extension (Ex), lateral bending (LB), and axial rotation (AR). C1-C2 range of motion (ROM) and screw-rod peak Von Mises stress (PVMS) were measured. Modified C1 lateral mass screw fixation reduced C1-C2 ROM by 19.67% (flexion-extension) to 48.51% (lateral bending) compared with occipital plate fixation. In flexion/extension/axial rotation, C1 lateral mass screw fixation increased screw-rod peak Von Mises stress (PVMS) by 51.17%-131.37% in the AOZ-BI group and 36.51%-56.02% in the AOZ-AAD group; in lateral bending, PVMS decreased by 19.46% in the AOZ-BI group but increased by 5.24% in the AOZ-AAD group. occipital plate fixation consistently had higher ROM (Group B highest) but lower PVMS. Modified C1 lateral mass screw fixation provides superior C1-C2 stability for AOZ-associated BI-AAD but increases implant stress in Fe/Ex/AR. Occipital plate fixation is less stable but reduces stress. Clinically, C1 lateral mass screw is preferred for AOZ-BI; AOZ-AAD requires balancing stability and stress risk. Occipital plate suits patients with severe C1 lateral mass hypoplasia. FEA effectively evaluates craniocervical fixation biomechanics.
Motor systems must balance stability and flexibility to enable efficient and adaptive movements, yet the circuit-level mechanisms generating their intrinsic dynamics remain poorly understood. Here, we investigate the head exploratory behavior of Caenorhabditis elegans, a minimal system capable of intricate motor patterns. Using variational mode decomposition, we identified two distinct motor dynamics: slow rhythmic bends propagating along the body and fast, phase-specific head casts influencing directional bias. Combinatorial ablations of three classes of cholinergic motor neurons, in conjunction with dynamical systems analysis, revealed their distinct and overlapping roles: RMD contributes to head casts, SMD sustains bending states, and SMB and SMD enable slow rhythmic bending and head-body coupling. Collectively, these neurons form a major rhythm generator that sustains undulatory forward locomotion. We propose a model where dual-proprioceptive feedback operates across multiple timescales, with slow feedback coordinating rhythmic bending and fast feedback shaping head casts to optimize roaming efficiency. Our findings highlight how complex, structured dynamics emerge from highly interactive low-level circuits.
Flexible perovskite solar cells and modules are limited by buried-interface nonuniformity and the thickness-sensitive, aggregation-prone nature of conventional small-molecule self-assembled monolayers, which create local recombination hot spots and crack-initiated degradation during large-area coating and bending. Here we introduce asymmetric polymeric self-assembled layers based on poly(4-(3-phenyl-9H-carbazol-9-yl)butyl phosphate) (Poly-3Ph-4PACz), a polycarbazole phosphonic acid featuring rigid phenyl-carbazole units and multiple anchoring sites. The polymeric architecture yields a dense, highly wetting and electrically homogeneous hole-selective contact with enhanced interfacial dipole and strong perovskite binding, enabling uniform crystallization, reduced non-radiative losses and effective stress buffering. Flexible devices reach 26.13% champion power conversion efficiency, while 57.6 cm2 flexible modules deliver 22.22%. Encapsulated modules retain 97.23% after 3000 bending cycles and show damp-heat resilience with T95 > 1000 h at 85 °C/85% RH. Beyond flexibility, Poly-3Ph-4PACz enables 27.18% rigid inverted perovskite solar cells (certified mean steady-state 27.12%) and a certified 32.95% perovskite/Si tandem efficiency. These results establish polymeric self-assembly as a scalable route to high-efficiency, durable flexible photovoltaics.
Electronic skin demonstrates significant potential for wearable health monitoring and human-machine interaction. However, conventional hydrogels rarely achieve a balance of high strength, fatigue resistance, sensitivity to subtle deformations, and conformability to complex curved surfaces. They often suffer from mechanical degradation, signal drift, and insufficient interfacial adhesion under repeated loading. Here, we propose a synergistic strategy integrating multibond crosslinking reinforcement with structural configuration amplification to develop a PVA/PAA/Zr4+ ion-conductive hydrogel strain sensor featuring a re-entrant honeycomb negative Poisson's ratio structure. At the material level, PVA/PAA hydrogels are fabricated via one-pot in situ photopolymerization followed by freeze-thaw-induced crystalline crosslinking. Incorporation of Zr4+ coordination, together with a high-density hydrogen-bond network, establishes a dynamic dissipation-reconstruction mechanism, thereby markedly improving strength, toughness, and fatigue durability. Structurally, the re-entrant honeycomb geometry amplifies strain and mitigates local stress concentration through unit rotation and beam bending, enhancing low-strain signal resolution and surface adaptability. The resulting hydrogel sensor delivers a maximum tensile stress of 552.9 kPa and an elongation at break of 629.4%. It provides a broad sensing range of 0.1-200% with a 0.1% resolution and a response time of 94.2 ms while maintaining stable outputs under cyclic deformation. As application demonstrations, the hydrogel sensor enables discrimination of soft gripper bending states and grasped object sizes, conforms tightly to dynamically changing curved surfaces, and supports continuous abdominal skin-contact respiratory monitoring with clear differentiation among distinct breathing patterns. Overall, this work establishes a reliable material-structure integrated design paradigm for hydrogel-based electronic skin, promoting its development toward wearable physiological monitoring.
This laboratory study aimed to compare the performance of non-ion and ion-releasing restorative composites. This in vitro experimental study was conducted at King Saud University from March 2025 to June 2025. The study groups included four bulk-fill restorative composites, consisting of two conventional non-ion-releasing formulations-Filtek Bulk and Tetric EvoCeram Bulk Fill-and two ion-releasing formulations-Beautifil Bulk Restorative and ACTIVA BioACTIVE Bulk. A total of 25 samples were prepared per group: five disc-shaped (n = 5/group) for depth of cure, ten disc-shaped (n = 10/group) for water sorption and solubility, and ten bar-shaped (n = 10/group) for bending strength testing. The one-way analysis of variance followed by Tukey's post hoc tests for multiple comparisons was conducted with a significance level set at P = 0.05. Filtek Bulk demonstrated the highest depth of cure (4.34 ± 0.29 mm) and bending strength (123.34 ± 9.05 MPa), succeeded by Tetric EvoCeram Bulk Fill (3.81 ± 0.17 mm, 115.78 ± 10.98 MPa). Additionally, Filtek Bulk and Tetric EvoCeram Bulk Fill exhibited significantly lower water sorption (0.49 ± 0.13% and 0.79 ± 0.10%, respectively) and solubility (0.01 ± 0.00% and 0.04 ± 0.00%, respectively) compared to ion-releasing composites, Beautifil Bulk Restorative and ACTIVA BioACTIVE Bulk (1.26 ± 0.19% and 1.42 ± 0.20%; 0.10 ± 0.01% and 0.14 ± 0.01%, respectively) (P < 0.05). While ion-releasing composites offer the benefit of reducing secondary caries risk and remineralization of the tooth, their physical and mechanical properties may not be on par with those of conventional non-ion-releasing restorative composites, potentially affecting their long-term performance in deep restorations. Therefore, the clinicians are advised to exercise caution in using these restorative composites.
Supracondylar humerus fractures are common pediatric injuries requiring surgical fixation. Beyond technical factors, medial column comminution may substantially influence construct stability, yet its biomechanical impact across different three-pin configurations remains unclear. One hundred twenty synthetic humeri were assigned to six groups (n = 20). Medial comminution was simulated by 25% (small) or 50% (large) wedge removal. Three lateral divergent pinning (3LDP) and two lateral one medial crossed pinning (3XP) configurations were tested under varus bending, torsion, and photographic displacement analysis. In torsional testing, the 3XP configuration showed significantly greater stiffness and maximum torque than 3LDP across all wedge sizes (P < 0.005), including the intact condition (stiffness: 1.19 ± 0.29 vs. 0.51 ± 0.16 Nm/°; maximum torque: 10.70 ± 2.22 vs. 5.37 ± 1.59 Nm). In varus bending, large wedge removal significantly reduced maximum load in the 3LDP group (256.58 ± 50.26 vs. 214.03 ± 37.22 N; P = 0.045), while no wedge-related differences were observed in the 3XP configuration. Fracture-line displacement increased with wedge removal in both constructs (e.g. 0.88 ± 0.41 to 2.23 ± 0.40 mm in 3LDP; P < 0.001); wedge size significantly affected displacement in 3LDP, whereas in the 3XP configuration, displacement increased with wedge removal but did not differ significantly between small and large wedge sizes. Increasing medial comminution negatively affected stability, particularly in lateral-only three-pin fixation. 3XP constructs showed greater torsional resistance and preserved varus stability in this synthetic model. These findings provide biomechanical insight into fixation behavior in unstable supracondylar fractures.
The purpose of this study was to develop a novel, low-cost, moldable cervical spine surrogate through topology optimization, using a validated human body model as ground truth to guide design and ensure biofidelity during multiplanar loading. The Global Human Body Models Consortium 50th percentile male pedestrian model (GHBMC M50) was used to establish multiplanar behavior by isolating the osteoligamentous cervical spine (OLS). Planar loading simulations in LS-Dyna were conducted to characterize the OLS response. These outputs served as target metrics for topology optimization to generate an anatomically inspired cervical spine surrogate. The optimization aimed to minimize volume fraction while constraining the design within volumetric bounds loosely defined by the GHBMC M50P OLS geometry and enforcing sagittal symmetry. Material properties of a two-part resin selected for fabrication were integrated into the optimization to ensure mechanical fidelity and enable a single-part, single-pour design. The final surrogate was fabricated using a custom two-part mold and tested under flexion, extension, and lateral bending using a six-degree-of-freedom robotic platform replicating the original simulation conditions. Trajectory-matched comparison of the GHBMC-M50 OLS and the novel surrogate yielded 1.5 N-m, 1.3 N-m, 0.1 N-m, and 0.2 N-m differences in moment required to traverse a physiologically relevant range of moment in flexion, extension, and left and right lateral bending respectively. Preliminary validation testing demonstrated that topology optimization enabled the creation of a monolithic, low-cost resin surrogate capable of replicating the biofidelic behavior of the GHBMC-M50P OLS.
Maintaining a dynamic balance of neurotransmitters such as dopamine and serotonin is fundamental to normal brain function. Real-time monitoring combined with localized chemical delivery may provide a useful strategy for decoding dysregulated neurochemical signaling and supporting future intervention studies in Parkinson's disease, depression, and related neurodegenerative conditions. Here we present a flexible sensing probe that combines high-surface-area rGO/PEDOT:PSS nanocomposite electrodes for fast electrochemical detection with a coplanar microfluidic channel for controlled localized delivery. The device simultaneously quantifies dopamine and serotonin over 0.1-100 μM and hydrogen peroxide over 0.1-1000 μM, achieving sensitivities of 1.89, 2.05, and 328.36 μA μM-1 cm-2, respectively, while exhibiting minimal interference from physiologically relevant analytes such as GABA and uric acid. Fluidic characterization demonstrated on-demand drug pulses on the order of seconds at flow rates ≥0.2 mL h-1, with negligible variation in flow under bending angles ≤30°. Electrochemical tests likewise confirmed stable sensing performance at a bending angle of 30°, consistent with the mechanical robustness required for chronic implantation. By integrating real-time neurochemical monitoring with localized microfluidic delivery in a compact flexible system, this platform provides an engineering basis for future closed-loop neurochemical studies, while direct biological regulation of neurotransmitter balance through local drug injection will require further in vivo validation.
Quadrupedal animals like mice navigate their environments through complex coordination of neural signals and biomechanical movements, enabling stable and directed locomotion. While many computational models simplify this process by assuming left-right symmetrical body movements and focusing on straight-line paths, real animals rely heavily on asymmetrical body movements to execute turns and adjust speed effectively. This study builds upon a previously developed model of quadrupedal locomotion proposed by (Molkov et al., Royal Society Open Science, 2024, 11(8)) in which forward movement of the body was driven by central neural interactions, biomechanics, and proprioceptive feedback. We extended this model to comparatively investigate possible mechanisms of steering by introducing three distinct asymmetrical strategies-body bending, lateral force application, and lateral limb shifting as well as their combinations-to explore their potential involvement in turning performance. By simulating these strategies across a walking speed range, we measured and compared their impact on turning curvature (the sharpness of the turn) and limb coordination. The latter was quantified through ratios of duty factors representing the relative time that a limb spent in contact with the ground compared to its counterpart on the opposite side. Our findings reveal that each strategy excels at different speeds: body bending allows sharp turns at low speeds, lateral force is most effective at medium speeds, and lateral shifting performs best at higher speeds. Our results suggest that animals select or combine turning strategies based on their locomotor speed or adjust speed to use a specific strategy. We also show that the forelimbs consistently play a primary role in steering, while the hindlimbs adjust propulsion and stability in ways that depend on the specific turning strategy. These results provide valuable insights into how spinal circuits and mechanical asymmetries work together to produce flexible, adaptive movement patterns, offering a robust framework for understanding locomotion in both biological organisms and robotic systems designed to mimic such behaviors.
Metal-organic hybrid materials have attracted a great deal of research inter-est due to their potential applications in the field such as gas storage and separation, heterogeneous catalysis, chemical/biological sensing and detection, energy transfer and photocatalysis, etc. The rational design and synthesis of organic ligands has proven to be an effective strategy in fabricating desired structures with given properties. Anthra-quinone-1,8-di-sulfonic acid (1,8-H2AQDS, C8H14O8S2) has been used to construct the title complex, {[Na2Cu(1,8-AQDS)2(H2O)6]·2H2O} n , by means of half-neutralization with NaOH followed by assembly with Cu(NO3)2·3H2O. This mixed-metal coordination polymer exhibits a three-dimensional pillar-layered framework structure with the 1,8-AQDS2- ligand adopting a μ5 -bridging mode, including a coordinated carbonyl group binding with Na+ cation. The Na+ and Cu2+ cations both exhibit a distorted octa-hedral coordination environment, in which the Na+ coordination sphere is more irregular stretched. The 1,8-substituted bulky sulfonate groups exert a strong stereo effect to the inter-positioned carbonyl group and lead to the bending of the 1,8-AQDS2- ligand into a butterfly conformation. Both coordinated and solvent water mol-ecules are involved in O-H⋯O hydrogen bonding, which further consolidates the three-dimensional coordination framework.
All polymer organic solar cells (APSCs) demonstrate distinctive advantages in balancing device efficiency while enhancing operational stability, particularly regarding mechanical robustness. However, their power conversion efficiency (PCE) has long been behind that of the corresponding devices with small molecular acceptors. This is due to the precise chemical structure modulation of polymer acceptors (PAs), enabling relatively coplanar conformation and ordered molecular stacking and thus achieving ideal morphology, which remains critically challenging. Herein, in this work, we have designed two biaxial conjugate extension PAs, with various side chain/terminal substituents to control their intermolecular non-covalent interactions, thereby optimizing aggregation behavior and microstructural orientation of polymer assemblies. It was found that the alkoxy-functionalized PQxO-IT facilitates stronger intermolecular interactions and tighter π-π stacking. Furthermore, the PQx-FT:PQxO-IT composite promoted charge carrier mobility and charge transport, while effectively suppressing non-radiative decay pathways. Consequently, the corresponding ternary device achieved the highest PCE of 20.29% (certified as 20.03%) for the APSC systems so far. Furthermore, the tight and ordered molecular packing endowed the flexible device with a PCE of 18.93% and remarkable durability during continuous bending tests. This study demonstrates a precise structure modulation strategy that offers a viable materials design pathway for high-performance flexible photovoltaics.
Self-powered flexible sensors represent indispensable components in tactile sensing and wearable electronic systems. In biological organisms, intracellular and extracellular ion transport underpin the precise perception, transmission, and processing of tactile stimuli. Inspired by these natural mechanisms, four types of self-powered multifunctional sensors were developed based on the controlled motion of ions within cationic poly(diallyldimethylammonium chloride) and anionic sodium polystyrene sulfonate ionomers. The sensors exhibit a p-n junction configuration, where a depletion layer is established at the ionomer interface. Through the incorporation of 2D MXenes and 1D carbon nanotubes (CNTs), the electrical conductivity was optimized, yielding an open-circuit voltage of approximately 75 mV and a short-circuit current density of ∼67 µA cm- 2. The distinct rectification behavior (ratio ≈ 8.8) enables logic circuit functionality, while the tunable assembly of sensing units into arrays allows precise discrimination of compression, bending, and directional stress stimuli. Unlike conventional pressure-sensing arrays, each unit in the present system displays unique sensing characteristics. This work offers a new paradigm for the rational design of high-performance, self-powered ionic sensors for next-generation flexible and wearable electronics.
Trackability of thrombectomy catheters through tortuous cerebral vessels is a key determinant of mechanical thrombectomy success, particularly for large-bore aspiration catheters. Yet, the underlying biomechanical challenges remain unclear. This study integrates in silico and in vitro analyses to investigate catheter navigation in a flexible intracranial vasculature model. A silicone patient-averaged tortuous vessel model was used for experimental studies in a circulatory flow loop and reconstructed from CT imaging for computational simulations. Regarding the in silico part of the study, in contrast to prior work relying on tip-dragging or centerline-based advancement, we implemented clinically realistic catheter pushing mechanics. We varied the vessel compliance and catheter-vessel friction coefficients to understand their sensitivity toward navigation. Strong qualitative agreement emerged between simulated and experimental catheter paths. Key findings include: (i) realistic pushing produced trajectories distinct from tip-dragging, with the catheter naturally aligning along the outer curvature to generate supportive contact and it matches with in vitro experiments; (ii) increased vessel flexibility (2 MPa) markedly improved catheter advancement, whereas stiffer vessels (10 MPa and rigid) promoted kinking; (iii) catheter-vessel interaction was observed to be a critical factor in navigation, with low friction coefficient (F) enhancing trackability (F < 0.1) and high friction (F > 0.15) triggering bending and kinking. Incorporating vessel flexibility and clinically representative pushing mechanics is essential for accurate thrombectomy modeling. The presented framework accurately reproduces catheter behavior, particularly in curved segments, and offers predictive capabilities for device performance. These insights offer quantitative design guidance for next-generation microcatheters and aspiration catheters, highlighting the critical role of catheter-vessel mechanics in distal cerebral arteries.
Pyrophosphates have acquired considerable attention as a potential electrode material in energy storage devices owing to their strong covalent P-O bonds, which ensure structural stability, high electrochemical activity, and efficient ion migration. In this contribution, we synthesized copper pyrophosphate (Cu2P2O7) by using a simple co-precipitation method followed by calcination at 500 °C for 30 minutes. The monoclinic structure of the material with space group C12/c1 was confirmed by powder X-ray diffraction. The Cu2P2O7 bonds were confirmed using Raman spectroscopy, while Fourier transform infrared spectroscopy confirmed the bending vibration of P-O-P and P-O bonds. X-ray Photoelectron Spectroscopy validates the +2-oxidation state of copper and the +5-oxidation state of phosphorus. Field emission scanning electron microscope revealed that the interconnected porous morphology with a rough surface of the material provides abundant active sites for ion movements and facilitates electrolyte penetration. The symmetric supercapacitor device of Cu2P2O7 possesses an excellent specific capacity of 225 F g-1 with a power density and energy density of 3200 W kg-1 and 80 Wh/kg at a current density of 1 A g-1, respectively. The symmetric device retains about 90% of its initial capacity after 10 000 cycles at a current density of 1.5 A g-1. The symmetric device is capable to illuminate a single 3 V red light emitting diode continuously for 1 minute and 27 seconds. The electrochemical findings endorse the viability of Cu2P2O7 as a suitable electrode material for long-term energy storage applications.
