Cellular ceramic structures (CCSs) have promising application perspectives in various fields. Recently, additive manufacturing (AM), usually known as three-dimensional printing (3D printing), has been increasingly adopted to produce CCSs. Usually, the structural properties of additively manufactured cellular ceramic structures (AM-CCSs), i.e., lightweight characteristics, load-bearing capacity, toughness, unconventional properties, are traditionally investigated. Interestingly, AM technologies have a significant advantage in achieving the structure-function integration for CCSs. functional properties, e.g., electromagnetic property, acoustic property, thermal property, of CCSs can be achieved during the structural design synchronously. In this review, firstly, the AM technologies for CCSs are comparatively introduced. Then, structural AM-CCSs are summarized. After that, structure-function integrated AM-CCSs are further introduced in detail. Finally, challenges and opportunities towards structure-function integrated AMCCSs are forecasted. This review is believed to give some guidance for the research and development of CCSs. (c) 2022 The Authors. Published by Elsevier Ltd.

Given that they can replicate both the biomechanical and mechanobiological functions of natural bone, metal additively manufactured porous load-bearing bone implants present a significant advancement in orthopedic applications. Additive manufacturing (AM) of metals enables precise control over pore geometry, resulting in implants that provide effective mechanical support and minimize stress shielding. In addition to its mechanical benefits, the porous architecture of the implants facilitates essential mechanobiological processes, including the transmission of mechanical signals that regulate cellular processes such as adhesion, proliferation, and differentiation. Before clinical use, the implants should first be engineered to achieve a comparable elastic modulus to native bone, mitigating implant-induced bone resorption while promoting tissue regeneration. It is also noteworthy that the microstructural features of these implants support angiogenesis-a critical process for oxygen and nutrient delivery during bone healing. Despite their potential benefits, challenges remain in balancing mechanical stability for load-bearing applications with biofunctionality for effective integration and controlled degradation. This review comprehensively discusses the biomechanical and mechanobiological factors influencing the design and performance of additively manufactured porous bone implants, highlighting their potential to enhance clinical outcomes in bone repair and regeneration.

Ceramics can be traditionally classified as structural and functional ones. However, the miniaturization and multi-functionalization of various devices require ceramics to have both structural and functional properties. In this work, we aimed to develop structure-function integrated ZrO2-SiO2 nanocrystalline glass-ceramics (NCGCs) by in situ formation of homogenously distributed amorphous carbon. By reducing the calcination temperature of carbon-containing powder, organic carbon groups were partially retained in the powder and they transformed to amorphous carbon in the sintered NCGCs. At micrometer scale, the carbon was homogenously distributed in the NCGCs, avoiding the commonly encountered agglomeration problem of carbon fillers. The effects of carbon on the microstructure, mechanical properties, wear resistance, and dielectric properties of the NCGCs were investigated. Results showed that the in situ formed amorphous carbon was homogenously distributed in the ZrO2 nanocrystallites. Meanwhile, the amorphous carbon strongly bonded with the ZrO2-SiO2 NCGCs. Only a small amount of carbon was combusted even after annealing at 1000 degrees C for 3 h. The formation of amorphous carbon led to an improvement of nanohardness and wear resistance of the NCGCs, while slightly reducing Young's modulus and flexural strength. The electromagnetic wave transmission performances were improved due to the formation of amorphous carbon. The current study paves a new way for developing structure-function integrated glass-ceramics through in situ formation of carbon. The prepared structure-function integrated ZrO2-SiO2 NCGCs have great potential to be used as radome and antenna windows of aerospace aircrafts that work in harsh environment.

The superhydrophobic surface presents great application potential in self-cleaning, anti-icing, and other efficient filed of surface engineering. In this work, we suggested introducing superhydrophobic property to glass fiber/polyetheretherketone composite surface. The developed route involves preparation of functional prepregs using hydrophobic particles and subsequent thermal pressing of modified composite sheets. The results show that depending on the hydrophobic polytetrafluoroethylene contents in the resin mixture, it is possible to obtain the functional prepreg with tunable surface wetting, and ulteriorly control the interlaminar bonding of laminates. The optimized procedure of hot-pressing temperature indicates that the hierarchical microstructure played a crucial role in governing the super-hydrophobicity of the rough composite surfaces. As the sandblasted mold temperature increases from 300 degrees C to 360 degrees C, the water contact angle of pressed composite surfaces ranges from 98 degrees to 152 degrees. Furthermore, the surface exhibits excellent environmental durability. The main advantages of the proposed procedure are its environmental friendliness and expandability, which makes it very potential for driving the superhydrophobic surface to practical applications.

Conventional experientialism-inspired and intuition-inspired research on microwave-absorbing (MA) materials appears to lack efficiency. The present work aims to establish a scalable parametrization-design methodology for multifunctional coupled MA metamaterials involving up-front theoretical calculation and simulation predictions followed by experimental verification. A top-down parametrization-design methodology is proposed herein, which relies on the utilization of polymer-derived ceramics (PDCs) with flexible electromagnetic tunability as substrate materials, combined with tunable electromagnetic response via mathematical modeling of triply-periodic-minimal-surfaces shellular structures. In the process, preferred structural configuration and orienta-tion are screened with actual requirements while final fabrication in a single step is enabled by 3D printing technology. The effect of structural configuration and orientation on electromagnetic response is scrutinized and a novel optimization method for deterministic high-temperature MA properties is proposed. As-fabricated [111]-oriented Gyroid shellular MA metamaterials exhibit superior overall performance in the X-Ku band with wide-temperature adaptability. At room temperature, the minimal reflection loss (RLmin) value is -58.05 dB, effec-tive absorbing bandwidth (EAB) with RL <= -10 dB reaches 6.11 GHz, and the specific strength reaches 65.20 MPa/(g/cm3) at the ultralow density of 0.550 g/cm3. RLmin improves to -72.38 dB at 100 degrees C while EAB increases to 6.77 GHz at 300 degrees C and retains 5.60 GHz at 600 degrees C.

The concept of 3D printing metamaterials to produce structure-function integrated absorbing ceramics has attracted great attention. However, there is still a lack of guidance on how to design meta-structures to achieve the preparation of excellent electromagnetic (EM) absorbers. Herein, a kind of ultraviolet (UV)-curable polysiloxane (PSO) resin slurry was successfully designed. According to the results of CST simulation, the gyroid structure (GS) with good formability and high ceramic yield was obtained by vat photopolymerization (VPP). After pyrolyzed at 1100-1300 degrees C, the GS SiOC metamaterials with a density of 1.430 similar to 1.612 gcm(-3) have the minimum reflection loss (RLmin) of -59.96 dB at 2.90 mm and effective absorption bandwidth (EAB) of 4.20 GHz (8.2-12.4 GHz) at the thickness of 2.69-3.15 mm, covering the whole X-band EM wave. Moreover, the simulated reflection loss (RL) results of the GS metamaterials are consistent with the experimental values at different thickness. This strategy realizes the integration of simulation, modeling, experiment of EM absorbing metamaterials, and provides a new idea for the development of ceramic-based high temperature absorbing materials.
