Abstract Understanding the nature of active sites in metal‐supported catalysts is great importance towards establishing their structure–property relationships. The outstanding catalytic performance frequently ascribed to synergic effect different sites, which however not well spectroscopically characterized. Herein, we report direct detection surface Zn species and 1 H– 67 internuclear interaction between 2+ ions Brønsted acid on Zn‐modified ZSM‐5 zeolites by high‐field solid‐state NMR...
Ingenious microstructure design and appropriate multicomponent strategies are still challenging for advanced electromagnetic interference (EMI) shielding materials with excellent effectiveness (SE) reliable mechanical properties in harsh environments low filling levels. In this study, nickel@multiwalled carbon nanotubes/alumina (Ni@CNTs/Al2O3) ceramic composites segregated structures electric/magnetic-coupling networks anchored by CNTs magnetic Ni nanofillers were prepared hot-press...
Abstract Highly porous foam ceramics exhibit broad prospects for multifunctional applications. With the facile Pickering‐based foaming technique, wet foams consisting of nanoparticles (NPs) may high strengths. However, they also experience linear shrinkages as 50% after drying and sintering process. Suitable solutions improving this situation have not been found yet. This work develops a method fabricating NP‐made by tuning interfacial chemistry Pickering system. Trace amounts ethanol are...
Zeolites are highly sensitive to water, which significantly affects their acidity─a key factor in catalytic reactions. This study investigates the dynamic interactions between water and often overlooked active sites, specifically "NMR-invisible" aluminum species (tricoordinated framework Al─FAL cationic extra-framework Al─EFAL) ultrastable Y (USY) zeolite under ambient conditions. Using solid-state NMR spectroscopy combined with theoretical calculations, we demonstrate that readily undergoes...
Porous ceramics are good candidates for thermal-insulating materials. Glass is a low-cost material that possesses low intrinsic thermal conductivity of less than 10 W·m-1·K-1. However, the mechanical strength homogeneous glass fairly low. We, in this work, have fabricated Al2O3-hollow sphere (HGS) foam with facile particle-stabilized foaming method. The obtained ceramic presents hierarchical microstructure rare to be seen elsewhere using technique. system contains two types particles having...
The growth of SiC nanowires (SiCNWs) plays a vital role that determines the microstructure and dielectric absorption properties. With SiCNW growth, regulating space atmosphere nanowire is an important method to determine its performance. In this article, we propose novel approach control SiCNWs. precursor prepares high-porosity foams based on particle-stablized foaming process. SiCNWs are adjusted by controlling porosity reaction conditions. Adjusting foam indirectly coordinates individual...
Using antifreeze compound in negative temperature concrete construction can not only reduce the liquid freezing point of concrete, promote coagulation and achieve water-reducing effects, but also improve early strength concrete. Through test, compounded basically with acrylic polycarboxylate super plasticizer (acrylic acid series for short) good liquidity fluidity, low slump loss, enhancements particular great potential to enhance many other performance characteristics.
Abstract Engineering mechanically robust ZrO 2 foams with three‐dimensional (3D) reticular architecture and high porosity is extremely challenging. In current work, we presented an approach for constructing such cellular ceramics via a combined polyurethane foaming chemical grafting method. Ester functional groups were chemically grafted on the powder surface to enhance its dispersibility. This caused micron‐sized windows assemble onto cell wall of porous framework, contributing 3D...
摘要: 针对厚规格钢/铝复合板坯料厚度大、组元差异显著、难以直接轧制复合等特点,采用等离子涂覆技术与热轧复合工艺相结合成功制备了厚规格钢/铝复合板,通过结合界面剪切强度测试和SEM、EDS等检测方法,分别探究了轧制道次、温度与压下率对界面结构与力学性能的影响规律。结果表明,与直接轧制复合相比,经表面喷涂处理后的界面结合强度明显提高,且拉剪断裂面均位于钢与涂层界面。在单道次轧制条件下,随着轧制压下率增加,钢/涂层的微观界面得到改善,界面结合强度逐渐提高。在400~500℃范围内,钢/铝界面扩散层厚度随轧制温度提高呈增加趋势、界面结合强度先增大后减小。由于变形的不协调性,增加轧制道次会破坏前一道次界面复合结果,导致结合强度剧烈下降。当轧制温度为450℃、单道次压下率为40%时,钢/铝复合板界面剪切强度达66 MPa,符合相关标准要求。研究成果为厚规格钢/铝复合板生产制备提供了一种新途径。
