Article Abstract
The poor interfacial compatibility of natural fiber-reinforced polymer composites has become a major challenge in the development of industry-standard high-performance composites. To solve this problem, this study constructs a novel rigid-flexible balanced molecular crosslinked network transition interface in composites. The interface improves the interfacial compatibility of the composites by balancing the stiffness and strength of the fibers and the matrix， effectively improving the properties of the composites. The flexural strength and flexural modulus of the composites were enhanced by 38 % and 44 %, respectively. Water absorption decreased by 30 %. The initial and maximum thermal degradation temperatures increased by 20 °C and 16 °C, respectively. The maximum storage modulus increased by 316 %. Furthermore, the impact toughness was elevated by 41 %, attributed to the crosslinked network's efficacy in absorbing and dissipating externally applied energy. This innovative approach introduces a new theory of interfacial reinforcement compatibility, advancing the development of high-performance and sustainable biocomposites.

Solid polymer electrolyte (SPE) among the most promising candidates for lithium metal battery (LMB) due to ease of processing and excellent electrode compatibility. However, balancing ionic conductivity and mechanical strength remains a key challenge. To address this, we designed and synthesized a star-shaped plasticizer using a straightforward thiol-acrylate photopolymerization process to enhance the overall performance of crosslinked SPEs.

Amphibious robots require efficient locomotion strategies to enable smooth transitions between terrestrial and aquatic environments. Drawing inspiration from the undulatory movements of aquatic organisms such as cuttlefish and knifefish, this study introduces a bio-inspired propulsion system that emulates natural wave-based locomotion to improve adaptability and propulsion efficiency. A novel mechanism combining crank-rocker and sliding components is proposed to generate wave-like motions in robotic legs and fins, supporting both land crawling and aquatic paddling.

Ionogels, as emerging stretchable conductor materials, have garnered significant attention for their potential applications in flexible electronics, particularly in wearable strain sensors. However, a persistent challenge in optimizing ionogels lies in achieving a balance between enhanced mechanical properties and electrical conductivity. In this study, we successfully addressed this challenge by incorporating carbon nanotubes (CNTs) into ionogels, achieving a simultaneous improvement in the electrical conductivity (2.

Expanding the imaging field of view (FOV) of medical ultrasound transducers will more effectively detect pathological behaviors of tissues or organs. Conventional rigid transducers can be realized by increasing the number of array elements or the curvature; however, the imaging aperture is fixed by the original size and shape during the manufacturing process. This article presented a 128-element, 3-MHz flexible curvature abdominal array (FCAA) with the goal of dynamically expanding the FOV within a 120° range.

Article Synopsis
- Graphite anodes show promise for potassium-ion batteries (PIBs), but their use is limited due to poor performance linked to significant expansion during cycling.
- Researchers developed a new type of carbon, called partial graphitic carbon (PGC), that balances highly graphitized areas for potassium ion absorption with amorphous carbon regions that support expansion and ion movement.
- The optimized PGC12 electrode demonstrated impressive performance, achieving a reversible capacity of 281.9 mAh/g, excellent cycle stability, and a high energy density of 148.2 Wh/kg, showcasing potential for enhanced K-ion storage in future PIB designs.
