Tendon healing after ligament or tendon reconstruction remains a significant challenge. Regenerative tissue engineering, an interdisciplinary field that combines biology, materials science, and engineering, offers promising solutions. Recent developments have introduced scaffold materials designed to enhance the proliferation and differentiation of tendon-to-bone tissue cells. These scaffolds possessing three-dimensional composites of tissue cells and biomaterials, have proven effective in facilitating tendon-to-bone curing post-surgery. The successful development of the tendon-to-bone interface is a critical factor for early rehabilitation and functional recovery. In this mini-review, we present a comprehensive update on contemporary strategies for synthetic scaffold-based materials and their influence on tendon-to-bone healing. We described the synthetic materials compositions, structures and features of single-layer, multi-layer, and gradient scaffolds with their special mechanical properties. We examined the construction of engineering scaffolds from the perspectives of biomaterials and design strategies, providing a comprehensive evaluation of the advantages and disadvantages associated with each approach. Ultimately, this review articulates clear research directions aimed at achieving breakthroughs in future studies.

In multi-user wireless communication scenarios, signal degradation caused by channel fading and co-channel interference restricts system capacity, while traditional enhancement schemes face challenges of high coordination complexity and hardware integration. This paper proposes an electromagnetic focusing method using a single-layer transmissive passive metasurface. A high-efficiency metasurface array is fabricated based on PCB technology, which utilizes subwavelength units for wide-range phase modulation to construct a multi-user energy convergence model in the WiFi band.

High safety gel polymer electrolyte (GPE) is used in lithium metal solid state batteries, which has the advantages of high energy density, wide temperature range, high safety, and is considered as a subversive new generation battery technology. However, solid-state lithium batteries with multiple layers and large capacity currently have poor cycle life and a large gap between the actual output cycle capacity retention rate and the theoretical level. In this paper, polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP)/polyacrylonitrile (PAN)-lithium perchlorate (LiClO)-lithium lanthanum zirconium tantalate (LLZTO) gel polymer electrolytes was prepared by UV curing process using a UV curing machine at a speed of 0.

Developing polymer dielectrics with stable high-temperature energy storage performance remains a pivotal challenge for next-generation electrical systems. However, the exponentially increasing conduction loss at elevated temperatures results in a decline in both energy storage density and efficiency. Herein, a cross-scale synergistic regulation strategy that integrates mesoscale free volume and molecular-scale charge trap, effectively addressing the issue of free volume collapse and space charge accumulation under thermal-electric coupling stress is proposed.

Thermal dynamics in cylindrical Li-ion batteries, governed by electrochemical heat generation, are critical to performance and safety in high-power applications such as electric vehicles and grid storage. Building on our previous work, which introduced and validated both single-layer and multi-layer models, this study focuses exclusively on experimentally validating the multi-layer formulation under a broader range of ambient temperatures. The proposed multi-layer model captures temperature evolution across all internal components, including the electrolyte, electrodes, current collectors, and casing, accurately resolving spatial heat accumulation.

In this study, a novel multi-layer scaffold composed of poly(ε-caprolactone) (PCL) and chitosan (CS) was designed and fabricated via electrospinning, with tigecycline (Tig) incorporated as an antimicrobial agent in the middle layer. This nanofibrous multi-layer structure consisted of hydrophobic PCL outer and inner layers and a hydrophilic PCL-CS-Tig middle layer, designed to mimic the structural functionality of the native extracellular matrix. SEM analysis revealed that the fabricated nanofibrous layers were uniform, beadless fibers with diameters ranging from 689 ± 186 nm for the pure PCL layers to 125 ± 19 nm in the PCL-CS matrix loaded with Tig (single-layer), and further increased to 298 ± 98 nm in the multi-layer dressing.
