Photocatalytic activity of Mo+Fe Co-doped titanium dioxide nanoparticles prepared by Sol-Gel method
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 28 - Trang 44-47 - 2013
Hailin Liu, Rui Xiong
Mo+Fe co-doped TiO2 nano powders were synthesised by sol-gel method. X-ray diffraction and transmission electronic microscopy morphologies showed that the Mo+Fe co-doped TiO2 nano powders were pure anatase phase, with the average crystallite size around 20 nm. UV-Vis and photocatalic activity measurements show that this Mo+Fe co-doped TiO2 can absorb visible light, have higher separation efficienc...... hiện toàn bộ
Effect of limestone powder on microstructure of concrete
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 25 - Trang 328-331 - 2010
Shuhua Liu, Peiyu Yan
The effect of limestone powder on microstructure of concrete was studied by using mercury intrusion porosimetry (MIP), backscattering scanning electron(BSE), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The experimental results show that the compressive strength of concrete containing 100 kg/m3 limestone powder can meet the strength requirement. Limestone powder has n...... hiện toàn bộ
The properties of the sintered copper powder liner
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 29 - Trang 269-272 - 2014
Nengquan Duan, Yonghong Gao, Junyuan Wang, Wenhua Du, Fengying Wang
In order to study the properties of sintered copper powder shaped charge liner, the copper powder, whose particle size was below 20 μm, was chosen as the main material. The mixed powders were directly pressed into the desired shape of the shaped charge liner by the top direct-pressure way. The microscopic morphology of the spinning shaped charge liner, the sintered and non-sintered powder liners, ...... hiện toàn bộ
Preparation of high performance green alumina ceramic balls by roller production waste
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 23 - Trang 134-138 - 2008
Lianyun Zhong, Bolin Wu, Lianmeng Zhang, Guifang Zhang
To reuse roller waste as a raw material of high performance green ceramic balls, three kinds of white alumina ceramic balls whose wear resistance were 2–3 times of the best high alumina ceramic ball with 90% Al2O3 were prepared, and the Al2O3 content of the prepared balls was 75%. It is found that the effect of calcia and magnesia on the wear resistance of ceramic balls is contrast to the accepted...... hiện toàn bộ

Optimization ofp-type segmented Bi2Te3/CoSb3 thermoelectric material prepared by spark plasma sintering
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 21 - Trang 126-129 - 2006
Wang Jun, Tang Xinfeng, Liu Haiqiang, Yang Xiuli, Zhang Qingjie
A kind of p-type segmented Bi2Te3/CoSb3 thermoelectric material was prepared by spark plasma sintering (SPS). When the segmented materials were used at the temperature ranging from 300 Koto 800K, the junction temperature was optimized, which is about 500 K, and the corresponding length ratio of CoSb3 to Bi2Te3 is about 15∶2. The measured maximum power output of segmented materials is about 320 W·m...... hiện toàn bộ
Hydrothermal synthesis and visible-light photocatalytic activities of SnS2 nanoflakes
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 30 - Trang 276-281 - 2015
Tiekun Jia, Zhiyu Min, Jianliang Cao, Guang Sun, Xiaodong Wang, Zhanying Zhang, Tingting Li
SnS2 nanoflakes were successfully synthesized via a simple hydrothermal process. The as-prepared SnS2 samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption-desorption isotherms, and UV-vis diffuse reflectance spectroscopy (DRS). The photocatalytic activities of the as-prepared SnS2 nanoflakes under visible light irradiation (λ>420 nm) were e...... hiện toàn bộ
Properties and Structure of PEO Treated Aluminum Alloy
Journal of Wuhan University of Technology-Mater. Sci. Ed. - Tập 36 Số 3 - Trang 424-432 - 2021
Shi, Yuanji, Wang, Yanyan, Cheng, Cheng, Guo, Xunzhong, Teng, Bingyan, Yu, Zhaopeng, Li, Junwan, Li, Wei
Plasma electrolytic oxidation (PEO) coatings were formed on 7075 aluminum alloy in silicateborate based electrolyte with different duty cycles. The physical and chemical properties of the PEO coatings were thoroughly investigated. The wearing and corrosion properties of the coatings were evaluated by wearing experiments and potentiodynamic polarization tests, respectively. The results showed that ...... hiện toàn bộ
Tính chất của keo PVF được biến tính bằng nano SiO2 Dịch bởi AI
Journal of Wuhan University of Technology-Mater. Sci. Ed. - - 2004
Chen He-sheng, Sun Zhen-ya, Xue Li-hui
Một số tính chất của keo PVF được biến tính bằng nano SiO2 đã được nghiên cứu. Kết quả thí nghiệm cho thấy nano SiO2 có thể cải thiện rất tốt các tính chất của keo PVF. Đồng thời, cơ chế biến tính của nano SiO2 đối với keo PVF và các ứng dụng của keo này trong vật liệu composite giấy-nhựa, bê tông và sơn chịu lửa đã được thảo luận thông qua việc xác định bằng IR và XRD.
