Cement-based materials have often been used for infrastructure construction and repair. The production of conventional Portland cement is energy-consuming and environmentally unfriendly. For example, production of one ton of Portland cement generates approximately one ton of carbon dioxide (CO 2 ) from calcining limestone and fuel use. It is estimated that cement production contributes 7% of to...

Multilayer ceramic capacitors (MLCCs) for electric vehicles require their room temperature capacitance to change ≤ ±15% at −55°C 200°C. The dielectric constant (ε) of BaTiO3, a material widely used in MLCCs, drops >125°C making its application difficult. Here, we propose KCa2Nb3O10 (KCNO)-layered perovskite as strong candidate vehicle MLCCs ε does not abruptly with temperature. effect sintering...

Lanthanum zirconate (LZO) has high-temperature advantages including high melting point, low thermal conductivity and structure stability, which the potential to be used in insulation field. However, mechanical properties of LZO porous ceramics have limited further applications. In this work, nanofibrous membranes were prepared by electrospinning, preparation parameters PVP content, spinning vol...

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...
