Summary: A universal spatiotemporal electrified (STE) approach is proposed to efficiently separate individual constituents from agglomerates, achieving one-step dispersion in the gas phase. The approach operates through periodic weak spark loosening and spatial electric field attraction, allowing for real-time separation and outputting of individual micro/nanomaterials.

Summary: This study demonstrates the application of flock-reinforced shear thickening gel in protective equipment. Three-dimensional woven fabrics with folded structures were efficiently manufactured using a modified loom, and 3D FRSTG/woven fabric composites were produced through a simple inclusion procedure. These composites exhibit flexibility and breathability, and show responsive impact resistance. Wearable protective applications prove the integration of breathability and impact resistance in these composites.

Summary: A novel carbon-based nanomaterial, carbonized polypyrrole nanotubes (C-PNTs), was used to fabricate copper composites. C-PNTs exhibited excellent self-dispersion characteristics and inherent interface bonding. Compared with commercially available carbon nanotubes (CNTs)/Cu composites, 0.3 vol% C-PNTs/Cu composites achieved significant improvement in mechanical-electrical properties and exhibited better corrosion resistance.

Summary: The development of electromagnetic wave absorbing materials and structures is of great importance in fields like aerospace and electronic communications. Traditional absorbing coatings have poor mechanical load-bearing capacity and struggle to meet lightweight requirements. In this study, a functional absorbing composite filament was developed using material extrusion technique, along with a magnetic lossy four-layer gradient honeycomb metastructure. The design enables effective absorption in the range of 6.09-37.18 GHz within a thickness of 16 mm, covering 81.82% of the frequency range of 2-40 GHz.

Summary: We report the development of a 3D printing process for producing soft glass optical fibers. The process involves direct printing using a miniaturized crucible and depositing straight horizontally-oriented lines to replace traditional assembly techniques. Experimental results demonstrate good performance of the printed photonic crystal fiber preform.

Summary: The aim of this study was to develop poly(lactic acid) (PLA)-based films with antioxidant activity by incorporating Malpighia emarginata DC pomace extract (MEPE). The results showed that MEPE exhibited good antioxidant activity and improved the antioxidant properties of the films. Despite changes in the physical properties of the films, they have potential for application as active food packaging.

Summary: This paper presents the development and self-sensing displacement of a new four degrees-of-freedom piezoelectric micromanipulator. The micromanipulator offers improved operational flexibility and avoids the need for external sensors through the self-sensing method. Finite element analysis is used to optimize the geometric parameters and a displacement self-sensing method based on charge integration is proposed. Experimental results show good agreement between the self-sensing method and laser sensors. In addition, an application for micro-shaft assembly is demonstrated.

Summary: This research conducts a systematic literature review (SLR) and content analysis on Supply Chain Coopetition (SCC) through the PRISMA framework. It examines the theory of coopetition and organizational relationships in intra-firm and inter-firm supply chains, focusing on collaboration between rival manufacturers. The study identifies structures and mechanisms of coopetition, such as buyer-supplier coopetition, supply networks coopetition, and production and distribution/logistics coopetition. It provides a holistic approach to SCC management practices and serves as a guide for future research.

Summary: This study focuses on the key issues of improving material removal rate and surface quality in macro-electrolyte jet machining. By introducing a novel tool with the rear-end tilted, the current density of the workpiece surface can be increased, leading to improved machining performance. Experimental results show that the tool with a rear-end tilt angle of 15 degrees significantly enhances the material removal rate and reduces surface roughness compared to the standard tool.

Summary: A progressive pseudograin damage accumulation (PPDA) model is proposed to predict the fatigue life of short fiber-reinforced plastics (SFRPs). The model combines the viscoelastic-viscoplastic (VEVP) two-step homogenization theory and Chaboche fatigue damage model. Each representative volume element (RVE) of SFRPs is decomposed into pseudograins, and the fatigue life of each pseudograin is predicted using a master S-N curve. The overall failure of RVE is predicted by a PPDA model, which takes into account the stress concentration of the living pseudograins and results in non-linear fatigue damage evolution. The PPDA model is implemented into ABAQUS, and the predicted fatigue lifetime agrees well with experimental data.

Summary: Metal-organic framework (MOF) derivatives have been found to be potential microwave absorbing materials (MAMs) due to their high porosity, abundant surface sites, and tunable constituents. This paper proposes an efficient microstructure controllable strategy for synthesizing thin-thickness broadband MAMs called NiFe@C. By controlling the supersaturation of precursors, different microstructures with specific absorption capabilities were obtained. This work provides a facile direction for designing thin thickness MAMs with broadband microwave absorption capability.

Summary: The global commitment to reducing carbon emissions has led to the use of sustainable carbon-fibre-reinforced thermoplastic composites (CFRTPs). When machining CFRTPs, challenges arise due to their ductile-brittle composition and sensitivity to high temperatures. This study conducted temperature-controlled cutting experiments to investigate the temperature-dependent cutting physics of CFRTPs and analyzed the microstructural morphology and damage using advanced microscopy. The experimental results were further explained using a finite element analysis model considering thermal softening.

Summary: In this paper, a novel OTA method is proposed that considers the relationship between tolerance of machine tools' key parts and volumetric error. A volumetric error prediction model is established based on the bridge between geometric error and tolerance. Additionally, a Processing Simplicity Index (PSI) is introduced to replace manufacturing cost and a tolerance-PSI model is established. An OTA model is formulated to minimize volumetric error and maximize PSI. The feasibility and effectiveness of the method are validated through simulations and experiments.
