Pomegranate-type Si/C anode with SiC taped, well-dispersed tiny Si particles for lithium-ion batteriesJournal of Advanced Ceramics - Tập 10 Số 5 - Trang 1129-1139 - 2021
Pengfei Wu, Benyang Shi, Huibin Tu, Chaozhong Guo, Anhua Liu, Yan Guan, Zhaoju Yu
AbstractSevere volume expansion and inherently poor lithium ion transmission are
two major problems of silicon anodes. To address these issues, we proposed a
pomegranate-type Si/C composite anode with highly dispersed tiny silicon
particles as the core assisted by small amount of SiC. Skillfully exploiting the
high heat from magnesiothermic reduction, SiC can assist the good dispersion of
silicon ... hiện toàn bộ
Enhanced ferroelectricity and magnetism of quenched (1−x)BiFeO3-xBaTiO3 ceramicsJournal of Advanced Ceramics - Tập 9 Số 4 - Trang 511-516 - 2020
Han Bai, Jun Li, Yang Hong, Zhongxiang Zhou
AbstractBismuth ferrite (BiFeO3)-based materials are multiferroic materials
widely studied. This study reports that strong ferroelectricity and enhanced
magnetic performance are simultaneously obtained in the quenched
(1−x)BiFeO3−xBaTiO3 (BFBT100x, x = 0.2 and 0.3) ceramics. Quenching treatment
can reduce the amount of defects and Fe2+ ions and make the defect dipole in a
random state, which is co... hiện toàn bộ
Ultralight and hyperelastic SiC nanofiber aerogel spring for personal thermal energy regulationJournal of Advanced Ceramics - Tập 11 - Trang 1235-1248 - 2022
Limeng Song, Bingbing Fan, Yongqiang Chen, Qiancheng Gao, Zhe Li, Hailong Wang, Xinyue Zhang, Li Guan, Hongxia Li, Rui Zhang
Multifunctionalization is the development direction of personal thermal energy
regulation equipment in the future. However, it is still a huge challenge to
effectively integrate multiple functionalities into one material. In this study,
a simple thermochemical process was used to prepare a multifunctional SiC
nanofiber aerogel spring (SiC NFAS), which exhibited ultralow density (9
mg/cm3), ultralo... hiện toàn bộ
Morphology and dielectric properties of single sample Ni0.5Zn0.5Fe2O4 nanoparticles prepared via mechanical alloyingJournal of Advanced Ceramics - Tập 3 - Trang 306-316 - 2014

Nickel-zinc ferrite nanoparticles are important soft magnetic materials for high
and low frequency device application and good dielectric materials. Nickel-zinc
ferrite nanoparticles with composition Ni0.5Zn0.5Fe2O4 were prepared using
mechanical alloying to analyze the effect of sintering temperature on
microstructure evolution of a single sample with dielectric properties. The
single sample with... hiện toàn bộ
Electrospun polyporous VN nanofibers for symmetric all-solid-state supercapacitorsJournal of Advanced Ceramics - Tập 7 Số 3 - Trang 246-255 - 2018
Dandan Zhang, Jing Li, Zhen Su, Sanyuan Hu, Heping Li, Yunjun Yan
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 features were
characterized by X-ray diffracti... hiện toàn bộ
Friction and wear properties of nano-Si3N4/nano-SiC composite under nanolubricated conditionsJournal of Advanced Ceramics - Tập 5 - Trang 145-152 - 2016
M. S. Charoo, M. F. Wani
Friction and wear properties of nano-Si3N4/nano-SiC composite were studied under
nanolubricated conditions. Mineral oil mixed with nanoparticles of diamond was
used as lubricant. A friction coefficient of 0.043 and a wear coefficient of
4.2×10-7 were obtained for nano-Si3N4/nano-SiC composite under normal load of
600 N with mineral oil + 0.5 wt% nanodiamond, whereas a friction coefficient of
0.077... hiện toàn bộ
Structure and composition study of carbon-doped titanium oxide film combined with first principlesJournal of Advanced Ceramics - Tập 3 - Trang 49-55 - 2014
Wei Mai, Feng Wen, Dong Xie, Yongxiang Leng, Zhonglin Mu
Carbon-doped titanium oxide (C/Ti-O) films were prepared on Si(100) wafer,
stainless steel (type 304) and glass by reactive magnetron sputtering (RMS)
using CO2 gas as carbon and oxygen source under room temperature (RT). X-ray
diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were used to
analyze structure and composition of the as-prepared C/Ti-O film. It could be
observed from XRD th... hiện toàn bộ
