Nevertheless, structural performance remainscritically limited by non-optimal material distribution and fiber placement. To address these challenges, this study proposes an integrated design-manufacturing framework comprising three innovations: (1) A conformal mapping-based topology optimization method incorporating a higher-order interpolation scheme (guaranteeingG<sup>1</sup> continuity) at lattice interfaces; (2) A fiber trajectory planning methodology specifically adapted for curved thin-walled structures; (3) Micro-computed tomography (μCT)-enabled defect characterization quantifying void spatial distributions in additively manufactured (AM) CFRC components. Simulation results demonstrate that the integrated honeycomb-stiffener structure achieves 57.3% and 44.5% maximum stress reduction compared to isolated honeycomb and stiffener benchmark structures, respectively. Comparative evaluation of fiber path planning methods reveals that the contour method achieves superiorfiber volume fractions in curved thin-walled structures. Three cases involving optimized design, CFRC-AM, and μCT inspection confirms the proposed framework.

This forms a hardness gradient up to 12 times higher than the Cu-rich soft phase regions. This heterogeneous structure achieves decoupled optimization of conductivity (35.8 % IACS) and wear resistance (average volumetric wear rate of 0.158 mm<sup>3</sup>/km, an 88.5 % reduction compared to the substrate) through a synergistic mechanism of “hard phase bearing wear load − soft phase maintaining conductive pathways”.

This method is unable to produce a complete stealth effect. In this work, the frequency selective rasorber (FSR) is theoretically analyzed. Based on this, a frequency-selective surface (FSS) and a patterned resistor film (PRF) are used to design the low-frequency transmission/high-frequency absorption (T-A) structure, which is then confirmed through simulation.

After 800 °C thermal treatment, the metastructure maintained excellent transmission coefficients at passband frequencies, demonstrating remarkable stability.

Currently, there is no specific therapy for SA-AKI, and clinicians can only rely on extensive supportive treatment. Therefore, finding effective methods for SA-AKI therapy is crucial to delay the progression of sepsis. Our previous studies have found that paricalcitol, an active vitamin D analog, can reduce renal inflammation and delay the progression of SA-AKI. However, expression inhibition of megalin caused by endotoxins can reduce the entry of active vitamin D into renal tubular epithelial cells and weakening its renal protective efficacy. Therefore, how to enhance the enrichment of paricalcitol in the kidney is a challenge. In this study, we constructed a nanodrug delivery system to enhance the enrichment of paricalcitol in the kidney by encapsulating paricalcitol into a poly lactic-co-glycolic acid (PLGA) nanosystem, forming PLGA@paricalcitol nanoparticles (PLGA@pari NPs). In vivo experiments demonstrated that PLGA@pari NPs exhibited higher accumulation in the kidneys and significantly improve renal function in septic mice. The study indicates that PLGA@pari NPs represent a simple, safe, and efficient drug delivery system that enhances the therapeutic efficacy for SA-AKI by improving renal accumulation.
