Although monolithic ceramics have many desirable properties, such as high-temperature resistance, excellent hardness, and chemical inertness, they also have limitations that can restrict their use in various applications. The limitations include, but are not limited to, low fracture toughness, low ductility, high electrical resistance, and low thermal conductivity. Researchers have been able to address some of these limitations by developing ceramic composites, nanocomposites, and hybrid nanocomposites. The later are ceramic matrices that incorporate two or more reinforcements. They represent an advanced class of materials that combine the excellent characteristics of monolithic ceramics and the outstanding properties of the reinforcements, offering exceptional mechanical, thermal, and functional properties for advanced applications. There are many comprehensive review papers on ceramic composites and nanocomposites, however, only one review paper on hybrid ceramic nanocomposites has been published, and it was dedicated solely to alumina-based nanocomposites prepared by spark plasma sintering. The aim of this work is to review the properties of hybrid ceramic nanocomposites, highlight their potential applications in various industries, and formulate directions for future research endeavors.
尽管单片陶瓷具有许多理想的性能,如耐高温、优异的硬度和化学惰性,但它们也有局限性,限制了它们在各种应用中的使用。其局限性包括但不限于低断裂韧性、低延展性、高电阻和低导热性。研究人员已经能够通过开发陶瓷复合材料、纳米复合材料和混合纳米复合材料来解决其中的一些限制。后者是含有两种或两种以上增强剂的陶瓷基体。它们代表了一种先进的材料,结合了单片陶瓷的优异特性和增强材料的优异性能,为先进的应用提供了卓越的机械、热学和功能性能。关于陶瓷复合材料和纳米复合材料的综合综述论文很多,但是关于杂化陶瓷纳米复合材料的综述论文只有一篇,而且是专门针对火花等离子烧结制备的氧化铝基纳米复合材料的。本文综述了杂化陶瓷纳米复合材料的性能,强调了其在各个行业的潜在应用,并提出了未来研究的方向。

Cordierites have exceptional thermal stability and resistance to thermal shock, rendering them particularly attractive for various industrial applications. Nonetheless, their mechanical properties are relatively modest when compared to other technical ceramics. Besides, their applicability is limited due to the simplicity of shapes achievable through current processing techniques. Reinforcing cordierite with graphene together with advanced manufacturing holds the promise of substantially enhancing their properties, thereby expanding their utility. This study establishes the groundwork for employing ceramic injection moulding (CIM) in the production of complex shape parts made of cordierite reinforced with reduced graphene oxide (rGO). The adequacy of direct rGO addition to the binder components for obtaining homogeneous rGO/powder dispersions and feedstock with good rheology is assessed. The debinding and sintering conditions are adjusted to maintain the graphemic species avoiding their degradation. The prevalence of graphene is tracked and demonstrated in all CIM steps by X-ray analysis and Raman spectroscopy. Sintered parts with properties exceeding that of base cordierite are accomplished, paving the way for innovative applications of cordierite–rGO composites in diverse industrial contexts.
堇青石具有优异的热稳定性和抗热冲击能力,使其在各种工业应用中特别具有吸引力。然而,与其他技术陶瓷相比,它们的机械性能相对适中。此外,它们的适用性受到限制,因为通过当前的加工技术可以实现的形状很简单。用石墨烯增强堇青石,再加上先进的制造技术,有望大大提高其性能,从而扩大其用途。本研究为采用陶瓷注射成型(CIM)生产由还原氧化石墨烯(rGO)增强堇青石制成的复杂形状零件奠定了基础。评估了直接将氧化石墨烯添加到粘合剂组分中以获得均匀的氧化石墨烯/粉末分散体和具有良好流变性的原料的充分性。调整脱脂和烧结条件,以保持石墨物质,避免其降解。石墨烯的普遍性是通过x射线分析和拉曼光谱在所有CIM步骤中跟踪和证明的。烧结部件的性能超过了基础堇青石,为堇青石-氧化石墨烯复合材料在不同工业环境中的创新应用铺平了道路。

Fused filament fabrication (FFF) is one of the most competitive additive manufacturing technologies which allow easy component customization for several sectors. Its application to the ceramic field is rapidly growing addressed by formulating high-loading composites in several binder systems which after the printing process, they are removed by a two-step debinding process. In this work, new granules and filaments of Al2O3 have been produced using a two-component binder system, consisting of polylactic acid (PLA) and polycaprolactone (PCL). Al2O3 feedstock is printed by FFF obtaining complex 3D structures and after a thermal one-step debinding and sintering cycle 100% Al2O3 components is obtained with a relative density of 96%.
The mixing process is based on a colloidal route where the ceramic particle surface modification improves its interaction with the binder. This improvement brings the possibility to increase the ceramic load in the composite up to 48 vol.%. Oscillatory melting rheology was measured to simulate the printing process. The incorporation of 25 vol.% PCL in binder is enough to modify the flow of the melt composite, enlarging the plastic solid-like flow where the Al2O3 composites are suitable to flow through the nozzle, and build adequate 3D structures using high-loaded feedstocks.
熔丝制造(FFF)是最具竞争力的增材制造技术之一,它允许多个部门轻松定制组件。它在陶瓷领域的应用正在迅速增长,通过在几种粘合剂系统中配制高负荷复合材料,在印刷过程后,通过两步脱脂过程将其去除。在这项工作中,使用由聚乳酸(PLA)和聚己内酯(PCL)组成的双组分粘合剂体系制备了新的Al2O3颗粒和长丝。Al2O3原料通过FFF打印得到复杂的3D结构,经过一步热脱脂和烧结循环,获得100%的Al2O3组分,相对密度为96%。混合过程基于胶体路线,其中陶瓷颗粒表面改性改善了其与粘合剂的相互作用。这一改进使复合材料中的陶瓷载荷增加到48vol .%成为可能。通过测量振荡熔融流变学来模拟印刷过程。在粘合剂中掺入25vol .%的PCL足以改变熔体复合材料的流动,扩大Al2O3复合材料适合流过喷嘴的塑料固体状流动,并使用高负荷的原料建立足够的3D结构。

Transition metal nitrides have gained attraction as electrocatalysts of diverse reactions under acid or basic conditions because of their high electric conductivity and excellent chemical stability. The design and control of porous structures are of great interest to enhance their catalytic ability. Herein, the role of a surfactant (triblock copolymer, Pluronic® F127) on the synthesis of titanium nitride by the urea-glass process is investigated. The effect of the surfactant on the catalytic activity is also elucidated. The addition of the surfactant is found to produce a mesostructured TiN with smaller pore diameters and larger pore volume than those without the use of the surfactant. Moreover, the use of the surfactant in the TiN synthesis leads to an improvement of the catalytic activity. Particularly, a four-electron oxygen reduction reaction (ORR) is observed for the TiN prepared by the surfactant-modified urea-glass process.

This study analyzes the structural and electrochemical properties of praseodymium- and gadolinium-doped ceria (CPGO) samples formed by the sintering reaction of Pr2NiO4+δ (PNO) and Ce0.9Gd0.1O2−δ (GDC). X-ray powder diffraction analysis confirmed a single-phase cubic CPGO structure as a primary phase. The cationic compositions were determined using energy dispersive spectroscopy (EDS) in a scanning transmission electron microscope (STEM), while core-loss electron energy-loss spectroscopy (EELS) was used to determine the valence of Ce and Pr. The compatibility between thermal expansion coefficients validated their integration with electrolytes at the typical Solid Oxide Cell (SOC) operation temperatures. Oxygen chemical diffusion and surface exchange coefficients were investigated using the electrical conductivity relaxation (ECR) method at intervals of partial oxygen pressures between 0.10 and 0.21 atm and 600 °C and 800 °C. Finally, the samples were tested in symmetrical cells by electrochemical impedance spectroscopy (EIS) between 700 °C and 850 °C. A polarization resistance of 0.17 Ω cm2 at 850 °C was obtained for CPGO air electrodes formed by sintering a mixture of 80% by weight of GDC and 20% by weight of PNO. These findings confirm that PNO–GDC mixtures forming CPGO oxides are excellent candidates for SOC applications.

Ferroelectric materials have attracted significant attention in recent decades because they can be used in various electronic devices. BiFeO3 (BFO) has a perovskite-type ABO3 structure with antiferromagnetic and ferroelectric properties and a band gap within the visible light range, making it a promising candidate for use in sensors and solar cells. In this study, BiFeO3 thin films were grown by radio frequency (RF) sputtering using a homemade target and sintered at different times to evaluate the influence of sintering time on their physical properties. Its physical properties were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. These results revealed that all films maintained a perovskite-like structure with rhombohedral and bismuth-rich secondary phases (Bi2O2.33). Atomic force microscopy (AFM) and piezoresponse force micrography (PFM) images depicted the impact of sintering time on surface roughness and ferroelectric domain reorientation. The optical properties, such as n, k, and the band gap of all samples, were obtained using reflection-transmission spectroscopy. The photoresponse under dark, visible and UV illumination were evaluated on BFO films grown over glass-FTO substrate.
近几十年来,铁电材料因其可用于各种电子器件而引起了广泛的关注。BiFeO3 (BFO)具有钙钛矿型ABO3结构,具有反铁磁性和铁电性质,并且在可见光范围内具有带隙,使其成为传感器和太阳能电池中有前途的候选物。本研究采用自制靶材,采用射频溅射法制备了BiFeO3薄膜,并对其进行了不同时间的烧结,考察了烧结时间对其物理性能的影响。利用x射线衍射(XRD)、扫描电镜(SEM)和拉曼光谱对其物理性质进行了评价。这些结果表明,所有薄膜都保持了钙钛矿状结构,具有菱形和富铋的二次相(Bi2O2.33)。原子力显微镜(AFM)和压电响应力显微镜(PFM)图像描述了烧结时间对表面粗糙度和铁电畴重定向的影响。利用反射-透射光谱法测定了样品的光学性质,如n、k和带隙。对生长在玻璃fto衬底上的BFO薄膜在暗光、可见光和紫外光下的光响应进行了评价。

This work addresses the use of Laponite® clay in various applications, focusing on its adsorption capacity and improvement of properties in water-based products. It describes the synthesis of Laponite® hybrids with the pigmented cyanobacterium phycocyanin (PC) to evaluate the adsorption capacity of the dye. This research addresses the importance of Laponite® clay in improving rheological properties of water-based products due to its ability to interact with components in aqueous solutions. Laponite® can be effectively dispersed in water, enhancing the dispersion of other elements in solution and preventing aggregation of solids. The structure and properties of synthetic Laponite® are described, highlighting its use in the textile industry as an additive for pigments and the formation of gels. Experimentally, Laponite® is used to adsorb phycocyanin, a cyanobacterial pigment, with the aim of achieving maximum adsorption. A design of experiments with different experimental conditions, including pH, addition of silane and surfactant, is used. A detailed analysis of the characterization of the resulting hybrids is presented, including colour, total solar reflectance (TSR), thermal analysis (TGA), EDS, FTIR and X-ray diffraction (XRD) measurements. The results show successful adsorption of the pigment in all experiments, with adsorption percentages above 97%. The colour of the hybrids is evaluated and the total solar reflectance is analyzed, highlighting their importance in applications such as coatings and printed textiles. Infrared spectroscopy and X-ray diffraction are used to study the structural properties of the hybrids. For future work, it is intended to be able to apply the hybrids obtained on an industrial scale in the colouring of textiles and plastic polymers.
