Abstract
To promote the energy density of symmetric all-solid-state supercapacitors (SCs), efforts have been dedicated to searching for high-performance electrode materials recently. In this paper, vanadium nitride (VN) nanofibers with mesoporous structure have been fabricated by a facile electrospinning method. Their crystal structures and morphology fea...... hiện toàn bộ
Microstructure and properties of porous Si3N4 ceramics by gelcasting-self-propagating high-temperature synthesis (SHS)Journal of Advanced Ceramics - Tập 11 - Trang 172-183 - 2021
Shile Chen, Liang Wang, Gang He, Jiangtao Li, Chang-An Wang
Porous silicon nitride ceramics have attracted a considerable attention due to their excellent overall performance, but poor porosity homogeneity and structural shrinkage induced by prolonged high temperature sintering limit its further application. Herein, as a three-in-one solution for the above issues, for the first time we develop a novel approach that integrates the merits of gelcasting-SHS (...... hiện toàn bộ
Controlling calcium and phosphate ion release of 3D printed bioactive ceramic scaffolds: An in vitro studyJournal of Advanced Ceramics - Tập 6 - Trang 157-164 - 2017
Lukasz Witek, Yang Shi, James Smay
This paper characterizes in an in vitro setting the release of calcium (Ca) and phosphate (PO4) of 3D printed bioactive ceramic scaffold prepared from extrudable paste containing hydroxyapatite and β-tricalcium phosphate (β-TCP). Hydroxyapatite and β-TCP were calcined at 800 °C for 11 h, fabricated into four experimental groups (100% HA, 100% β-TCP, 15%/85% HA/β-TCP, and 15%/85% HA/β-TCP (design))...... hiện toàn bộ
Gel-tape-casting of aluminum nitride ceramicsJournal of Advanced Ceramics - Tập 6 - Trang 67-72 - 2017

Aluminum nitride ceramic sheets were formed for the first time by a novel and simple method, namely gel-tape-casting process, where only two additives were used to prepare the slurries. PIBM (a water-soluble copolymer of isobutylene and maleic anhydride) acted as both dispersant and gelling agent, and PEG (polyethylene glycol) acted as plasticizer. Combining the advantages of gel-casting and tape-...... hiện toàn bộ
Effect of calcination temperature on structural and optical properties of MAl2O4 (M = Ni, Cu, Zn) aluminate spinel nanoparticlesJournal of Advanced Ceramics - Tập 8 - Trang 352-366 - 2019
Thanit Tangcharoen, Jiraroj T-Thienprasert, Chanapa Kongmark
NiAl2O4, CuAl2O4, and ZnAl2O4 aluminate spinel nanoparticles were synthesized by sol-gel auto combustion method using diethanolamine (DEA) as a fuel. The effects of calcination temperature on structure, crystallinity, morphology, and optical properties of MAl2O4 (M = Ni, Cu, Zn) have been investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron mi...... hiện toàn bộ
Mechanical properties and thermal stability of carbon fiber cloth reinforced sol-derived mullite compositesJournal of Advanced Ceramics - Tập 8 - Trang 218-227 - 2019
Wei Zhang, Qingsong Ma, Kuanhong Zeng, Songlin Liang, Weiguo Mao
For the wide application as thermal protection materials, it is very necessary for mullite ceramics to improve fracture toughness. In this paper, the laminated and stitched carbon fiber cloth preform reinforced mullite (C/mullite) composites were prepared through the route of sol impregnation and heat treatment using the Al2O3—SiO2 sol with a high solid content as raw materials. The C/mullite comp...... hiện toàn bộ
Inactive Al3+-doped La(CoCrFeMnNiAlx)1/(5+x)O3 high-entropy perovskite oxides as high performance supercapacitor electrodesJournal of Advanced Ceramics - Tập 11 - Trang 742-753 - 2022
Meng Guo, Yufeng Liu, Fengnian Zhang, Fuhao Cheng, Chufei Cheng, Yang Miao, Feng Gao, Jun Yu
A series of high-entropy perovskite oxides (HEPOs) La(CoCrFeMnNiAlx)1/(5+x)O3−δ (x = 0.4, 0.5, 0.6, and 0.7) have been synthesized by coprecipitation method combined with calcination process and explored as electrodes for supercapacitors. The crystal structure, microstructure, and elemental composition of HEPOs were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), trans...... hiện toàn bộ
