| 1 | M0S_(2) nanoparticles grown on carbon nanomaterials for lubricating oil additives显示文摘In this study,the nanocomposites of MoS_(2) nanoparticles(NPs)grown on carbon nanotubes(MoS_(2)@CNT),graphene(MoS_(2)@Gr),and fullerene C60(MoS_(2)@C60)were synthesized,characterized,and evaluated for potential use as lubricant additives.By using the benefit of the synergistic effect between MoS_(2) and carbon nanomaterials(CNMs),these nanocomposites can be well dispersed in polyalkylene glycol(PAG)base oil and show superior stability compared with pure MoS_(2) NPs.Moreover,the dispersions of MoS_(2)@CNT,MoS_(2)@Gr,and MoS_(2)@C60 added in PAG have noticeably improved friction reducing and antiwear(AW)behaviors at elevated temperature for comparison with that of PAG and PAG containing CNT,Gr,C60,and M0S2 NPs,respectively.The enhanced lubricating properties of these nanocomposites were also elucidated by exploring the tribofilm formed on the disc. | Kuiliang GONG Wenjing LOU Gaiqing ZHAO Xinhu WU Xiaobo WANG | 2021 | Friction2021，9，4： | 3 |

| 8 | Effects of Fleckvieh on the Performance of Dual-Purpose Cattle Improved by Hybridization with Local Beef Cows显示文摘[Objective] The paper aimed to study the improved effect of local beef cattle with Fleckvieh cattle and provide theoretical basic data for local cattle industry in central plain agricultural area in China. [Method] With 500 local beef cattle as female parents and Fleckvieh cattle as male parents,hybridization improvement was conducted via artificial insemination. The growth performance,slaughter performance,milk performance and milk components of F1 and F2 hybrids were measured. [Result] The birth body weights of F2 were significantly higher than those of local beef cow,but there was no remarkable difference between F1 and local beef cow or F1 and F2. The growth rates of F1 and F2 at different stages were higher than those of local beef cattle. The slaughter performance,such as carcass weight( P < 0. 05),dressing percentage,net meat rate( P < 0. 05),marbling score of F1 and F2 were higher than those of local beef cow. Milk production performance,such as actual milk yield,305 d corrected milk yield and 4% standard milk yield of F2 were signally higher than those of F1 and local beef cattle( P< 0. 05),and F1 was markedly higher than local beef cattle( P < 0. 05). For milk composition,although milk fat percentage,milk protein rate,lactose rate and total solids( TS) of F1 and F2 were slightly lowered compared with local beef cattle at varying degrees,they were still at high levels compared with Holstein cows.[Conclusion]Fleckvieh cattle,as a male parent,can significantly improved growth performance,slaughter performance and milk performance of offsprings. It would also increases the economic efficiency of local beef cattle by higher quality and price,as well as changing production model from beef to dual purpose of beef and milk. | Wang Linfeng Yang Gaiqing Lian Hongxia Yan Ping Liu Xian Liu Yan Wang Wenhui Zhu Ruiguang Li Ming Yang Guoyu | 2015 | Animal Husbandry and Feed Science2015，7，6： | 0 |
| 9 | Investigation on tribological behaviors of MoS2 and WS2 quantum dots as lubricant additives in ionic liquids under severe conditions显示文摘Despite excellent tribological behaviors of ionic liquids (ILs) as lubricating oils, their friction-reducing and anti-wear properties must be improved when they are used under severe conditions. There are only a few reports exploring additives for ILs. Here, MoS2 and WS2 quantum dots (QDs, with particle size less than 10 nm) are prepared via a facile green technique, and they are dispersed in 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm]PF6), forming homogeneous dispersions exhibiting long-term stabilities. Tribological test results indicate that the addition of MoS2 and WS2 QDs in the IL can significantly enhance the friction-reducing and anti-wear abilities of the neat IL under a constant load of 500 N and a temperature of 150 °C. The exceptional tribological properties of these additives in the IL are ascribed to the formation of protective films, which are produced not only by the physical absorption of MoS2 and WS2 QDs at the steel/steel contact surfaces, but also by the tribochemical reaction between MoS2 or WS2 and the iron atoms/iron oxide species. | Kuiliang GONG Wenjing LOU Gaiqing ZHAO Xinhu WU Xiaobo WANG | 2020 | Friction2020，8，4： | 0 |
