The inherent high conductivity and limited loss mechanism of graphene result in an impedance mismatch with free space impedance. Co2Y-type ferrite exhibits strong planar magnetic anisotropy and a high natural resonance frequency compared to other ferrites. Therefore, the utilization of Co2Y-type ferrite magnetic particles to impart magnetic loss capability to graphene is considered an effective strategy for enhancing electromagnetic wave absorption efficiency. Ferrite/RGO composite material with excellent microwave absorption properties was synthesized by coupling sol-gel derived Ba2Co2Fe12O22 hexaferrite with graphene oxide, followed by reduction using ascorbic acid. More noticeably, the ferrite particles stably adhere to the surface or interlayer of graphene through adsorption, while the reduced graphene oxide with residual oxygen-containing functional groups simultaneously enhances the dielectric …

Highly-parallel manufacturing is as revolutionary method for large area devices production with sub-micrometre scale features and/or structured surfaces. Nowadays, many devices are available by these fabrication processes, with the subsequent need to improve either in-line and off-line sampling-based controls. Among others, morphological characterizations and resistance measurements are often used for quality control of printed conductors, which features are simple lines or more complex structures. This study, performed on printed linear conductors deposited on flexible plastic sheets made by roll-to-roll process, exploit stylus and optical profilometers for the 3D surface characterization. A more accurate 3D reconstruction of the surface morphology was achieved by the stylus profiler; starting from these topographical measurements, the calculated resistance of selected lines has been compared to resistance measurements by electrical setup. In this work, morphology and roughness parameters of surfaces are characterized using specialized software tools (Mountains Map and SPIP). Resistance measurements are performed with the aim of identifying correlation between critical sizes/forms and functional features. A good repeatability of parameters together with some drawbacks and limitations due to probe size, shape, type of substrate and sampling time are highligthed. An uncertainty budget is estimated for each of the critical sizes and functional feature of the sample structures under test. Meanwhile, the development of application-oriented material measures to support traceability of quantitative measurements of function-correlated …

Core–shell structures are commonly employed in dielectric nanocomposites to improve the energy storage capacity of polymers. However, few studies have focused on organic–inorganic double-layered shell structures. Thus, there is an urgent need to elucidate the detailed effects of the flexible segment of polymer shells and inorganic shells on the dielectric properties. Herein, we synthesized a hierarchical core–double shell BT/PU/SiO2 nanofiller with a thickness of 3–5 nm PU and 15 nm SiO2 layers. This unique shell structure possesses a gradient permittivity that regularly decreases from the inside to the outside of shells. Detailed electrical characterizations reveal that the intermediate PU shell with shorter flexible segments can limit the carrier migration and thus decrease the dielectric loss. The interfacial polarization in double-layered BT/PU/SiO2 is beneficial to improve the dielectric constant of the as-prepared …

On-machine optical measurement receives growing attention as a viable quality assurance technique to satisfy the increasingly critical requirements for dimensional accuracy and surface finish upon precision components. It preserves the temporal and spatial consistency between manufacturing and measurement activities, allowing for a substantial productivity improvement and a great opportunity for on-line quality control. However, additional uncertainty can be introduced under the harsh on-machine measuring environment degrading the measurement quality. The explicit research on the on-machine measurement uncertainty is therefore essential but rarely carried out to date. To fill this gap, this paper presents the uncertainty investigation of an on-machine areal measuring instrument based on the chromatic confocal scanning principle.

Pulse classification is fundamental to real-time monitoring of the discharge status in micro-electrical discharge machining (micro-EDM). Traditional classifications mainly involve finely regulated thresholds imposed upon voltage and current waveforms but are often limited in generalization to other complicated or varying machining conditions. This paper presents pulse classification based on deep temporal neural networks (DTNNs) that have a superior capability of learning temporal features from time-series pulse signals. Two capable structures, ie 1D convolutional neural network (1D-CNN) and bidirectional long short-term memory (Bi-LSTM), are investigated and compared. These two DTNNs are both trained with more than 200,000 pulses. The ground-truth labels are efficiently generated based on the threshold-based approach followed by a post-evaluation using the derived discharge energy. The training results indicate that the 1D-CNN presents a better capability than the Bi-LSTM for capturing the pulse temporal features, as a result of its particular focus on the local receptive salience. More than 90% for the precision or recall scores on the testing dataset with varying parameters prove the generalization ability of both models. The application in discharge status monitoring shows the effectiveness of the DTNN classification model.

Electrochemical machining (ECM) removes material through anodic dissolution and has demonstrated excellent capabilities in machining difficult-to-cut materials, in particular for aerospace and biomedical sectors. ECM competes well with the laser and electrical discharge machining (EDM) processes especially, when it comes to preservation of microstructural properties and surface integrity. Due to its non-contact nature and flexibility, ECM has a high potential to be hybridized with other manufacturing processes such as laser, EDM and grinding to achieve several synergistic benefits such as weakening of passivation, improvement of accuracy and combination of high material removal rate with high surface quality in one machine. One of the major ECM based hybrid process is hybrid laserelectrochemical machining (LECM) which uses a laser source coaxially coupled to ECM process through a composite tool or nozzle. The laser can act as an ablating energy source or a localized and controllable heat source (assisting process energy) depending on the fluence on the workpiece side. The assisting application of laser facilitates ECM by weakening the passivation layer on highly passivating materials, uniform dissolution of multiphase materials through increase in electrolyte conductivity in the processing zone, increased removal rate through escalation of reaction kinetics as reflected in rise in machining current. This study presents an inhouse developed tool-based LECM technology. An overview of research and development efforts will be provided from machine-tool considerations, tooling aspects, fundamental process studies to processing of …

All-organic polymer dielectrics used in electrical and electronic systems have been proven to be an efficient option for large-scale industrial production. Modifying the side chain of polymers can improve the energy storage performance of polymers, but it can hardly solve the problem of failure under high-temperature application. Herein, an innovative approach is proposed to introduce a group with high temperature resistance into the main chain to reconstruct the chain structure to solve the abovementioned problem. Concretely, a naphthalene ring was introduced to the chain of polyphenylene benzodioxazole (PBO) that is the most promising polymer applied in a high-temperature environment. The naphthalene ring endows the molecular structure with both enhanced permittivity and breakdown strength by decoupling the conjugation of the main chain, increasing the dielectric constant. Meanwhile, an appropriate …

Rational design and fabrication of yolk–shell structure is evolving as an effective approach to improve electromagnetic wave absorption performance by enhancing the impedance matching, multiple reflections and scatterings, as well as promoting interfacial polarizations. However, due to the complexity of synthesis, it is still challenging to develop an absorber with yolk–shell structures intergrating two types of losses (dielectric and magnetic loss) simultaneously in the yolk and shell. Herein, novel yolk–shell Co/C nanocubes were successfully constructed via a controlled-etching with tannic acid followed by direct pyrolysis, in which the magnetic component Co and dielectric component C were uniformly distributed in the yolk as well as the shell. It was found that the pyrolysis temperature can adjust the graphitization degree of carbon and the crystallinity of metal Co, which effectively regulated the electromagnetic …

High-temperature electronic power systems need reliable dielectric energy storage materials, but conductive losses in extreme conditions impair their performance. Hierarchically-structured fillers are promising to not only integrate the benefits of diverse components but also effectively utilize interface engineering and electron scattering effects to optimize dielectric and breakdown properties, thereby modulating energy storage performance in polymer-based composites. In this work, we successfully fabricated hierarchical nanofillers comprising 2D boron nitride nanosheets (BNNS) and 0D ultrafine strontium titanate (ST) nanoparticles. The paraelectric ceramic ultrafine ST possesses a high dielectric constant and low residual polarization, which enhances the energy storage density of composite materials while ensuring high conversion efficiency.

The development of pulse power systems and electric power transmission systems urgently require the innovation of dielectric materials possessing high-temperature durability, high energy storage density, and efficient charge–discharge performance. This study introduces a core-double-shell-structured iron(II,III) oxide@barium titanate@silicon dioxide/polyetherimide (Fe3O4@BaTiO3@SiO2/PEI) nanocomposite, where the highly conductive Fe3O4 core provides the foundation for the formation of microcapacitor structures within the material. The inclusion of the ferroelectric ceramic BaTiO3 shell enhances the composite’s polarization and interfacial polarization strength while impeding free charge transfer. The outer insulating SiO2 shell contributes excellent interface compatibility and charge isolation effects. With a filler content of 9 wt%, the Fe3O4@BaTiO3@SiO2/PEI nanocomposite achieves a dielectric constant of 10.6, a dielectric loss of 0.017, a high energy density of 5.82 J cm−3, and a charge–discharge efficiency (η) of 72%. The innovative aspect of this research is the design of nanoparticles with a core-double-shell structure and their PEI-based nanocomposites, effectively enhancing the dielectric and energy storage performance. This study provides new insights and experimental evidence for the design and development of high-performance dielectric materials, offering significant implications for the fields of electronic devices and energy storage.

Despite being a widespread non-conventional processing technique, electrical discharge machining (EDM) has been complicated due to its removal mechanisms and weak process stability for decades. Process monitoring is an enabling technology to offer an indirect insight into the discharge phenomena, understanding the probabilistic anomaly events such as arcs and short circuits. However, the transient high-frequency pulse train poses a great challenge for statistical monitoring and control. Traditional approaches are limited to single pulse analysis, which hinders a deep understanding of the process. To address the challenge, this paper proposes a novel physics-informed deep learning architecture for real-time micro-EDM process monitoring. To prepare condition labels, a series of signal-processing techniques including sensory fusion, pulse-shape filtering and pulse segmentation are employed, followed by …

Surgical procedures are a staple of our healthcare system. While early traces of surgery date back as early as 3000 BC, technology has revolutionised surgery in the past 50 years. More and more procedures are possible while procedures become less and less invasive, reducing patient trauma and accelerating recovery. In the current age, Single-Port Access (SPA) surgery offers further reductions in invasiveness thanks to a single, small incision to insert long and thin instruments. However, where multi-port laparoscopic interventions are already difficult to perform due to a reduced and decoupled 2D vision, the loss of degrees of freedom, occasional tremor amplification due to long instruments and the fulcrum effect, SPA surgery is even more challenging. Collisions between instruments, obstruction between multiple clinicians operating next to the single port, poor triangulation of the operating site and a further loss of intuitive motion hamper SPA clinical adoption. Robotic assistance is regarded as having the potential to address the above-mentioned issues. This thesis aims at contributing to the emergence of novel surgical robotic platforms by investigating the potential of fluidic actuation to create smaller and modular approaches to surgery. Challenges for robot-assisted MIS are very different depending on whether one works in a confined and narrow space, such as transoral surgery or in a shallow and wide space, such as abdominal laparoscopy. One surgical procedure belonging to each category is selected to confront fluidic actuation to the whole spectrum of challenges inherent to surgical robots. The first part of this thesis investigates …

Improving the compatibility and dispersion between nanoparticles and polymers has become the key to enhance the dielectric properties. In addition, dielectric materials should also have excellent dielectric and thermal stability to meet the application under extreme conditions. Herein, we synthesized a core–shell structure BST@HBPI and BST@HBPI/PEI nanocomposite films. HBPI owns a chemical structure similar to polyetherimide (PEI), and the dipole moment of the polar group contained in it is small, so it can enhance the interface interaction between the nanoparticles and the matrix, hence effectively inhibiting the free charge, and reducing the leakage current in composite. The results show that the introduction of HBPI not only effectively improves the compatibility and dispersion of nanoparticles and polymer matrix, but also greatly enhances the dielectric properties and energy storage properties of …

Covalent organic frameworks (COFs) show great potential as sustainable porous materials, possessing several properties that make them suitable for sewage purification and rapid adsorption. In this paper, two novel COFs containing triazine and carboxyl bifunctional groups, DAA-TFPT-COF and PDA-TFPT-COF, were developed. The DAA-TFPT-COF and PDA-TFPT-COF have high specific surface areas and good metal ion adsorption properties. Moreover, they have behaved good metal ion adsorption ability in not only acidic but also alkaline environments, which is superior to ordinary adsorption materials.

In this work, an electrochemical hybrid additive (μECAM) and subtractive (μECM) micro-manufacturing process is realized on a lowcost 3D printer platform. These electrochemical processes do not impose any thermal load on the workpiece resulting in high surface integrity with preserved microstructure and material-functionality. This opens up future application potential to carry out multiple processes in same machine eg, repair, achieving surface roughness and dimensional tolerances, adding difficult features on machined parts as well as adding multi-materials on the same component. The details of the hybrid setup are presented, which can alternately perform μECAM and μECM. This helps in performing selective micromachining and selective deposition on the same workpiece to meet functional requirements. The developed setup and proof of concept is presented through copper feature deposition with μECAM along with feature machining with μECM on the same stainless steel (EN-1.4301) sample. Overall, this hybrid additive and subtractive electrochemical micromanufacturing opens up avenues to produce complex and multi-material components on one machining platform and in one clamp.

Micro-electrochemical additive manufacturing (μECAM) is reverse of electrochemical micro-machining (μECM) which is used for selective and localized deposition of material on a substrate. It can be used to manufacture small sized parts or deposit functional metal coatings on conductive surfaces. As the process is contactless and generates negligible joule heating, the deposited material is free from heat affected zones and has low internal stresses. This work presents a free-flow jet micro-electrochemical additive manufacturing (FJECAM) process that deposits material through a continuous stream of electrolyte. FJECAM can deposit accurate μm to mm scale features without the need for expensive masking and complex meniscus control as used in traditional μECAM configurations. This facilitates rapid surface modifications, surface coatings and deposition of 2D-2.5 D shapes with high accuracy. In this paper, the deposition mechanism of copper (Cu) on stainless steel substrate (SS) during FJECAM is investigated through the characterization of surface topography and analysis of process current. The micro-deposits with FJECAM at different voltages and scan rates were observed to be without porosities and a minimum surface roughness of 0.38±0.02 μm was achieved at a material deposition rate (MDR) of 16.06 μg/s which is 20 times higher than the traditionally used meniscus-confined μECAM (MECAM) at the same process parameters.

The hybridization of micro-ECM with laser facilitates machining of materials/alloys with conductivity variations and promotes their uniform dissolution. The process mechanism involves several multiphysics phenomena occurring in the interelectrode gap (IEG) which is of the order of 20-50 µm.
