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 assis...... hiện toàn bộ

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

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
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
