| 1 | Adhesion and surface forces in polymer tribology——A review显示文摘Polymer tribology is a fast growing area owing to increasing applications of polymers and polymer composites in industry, transportation, and many other areas of economy. Surface forces are very important for polymer contact, but the real origin of such forces has not been fully investigated. Strong adhesive interaction between polymers leads to an increase in the friction force, and hence, the asperities of the material may be removed to form wear particles or transfer layers on the counterface. The theory of polymer adhesion has not been completely elucidated yet and several models of adhesion have been proposed from the physical or chemical standpoints. This paper is focused on the research efforts on polymer adhesion with emphasis on adhesion mechanisms, which are very important in the analysis of polymer friction and wear. | Nikolai MYSHKIN Alexander KOVALEV | 2018 | Friction2018，6，2： | 15 |
| 2 | Comparative equilibrium studies of sorption of Pb(Ⅱ) ions by sodium and calcium alginate显示文摘The absorption of Pb(Ⅱ) ions from aqueous solution by different alginate compounds was studied in a batch sorption system.Water soluble sodium alginate and insoluble calcium alginate beads were investigated.The lead-binding capacity of both alginate compounds was highest within the pH range 6-8.The binding capacities and rates of Pb(lI) ions by alginate compounds were evaluated.The Langmuir,Freundlich,and Bruneaur,Emmet and Teller (BET) sorption models were applied to describe the isotherms and isotherm ... | KHOTIMCHENKO Maxim KOVALEV Valeri KHOTIMCHENKO Yuri | 2008 | Journal of Environmental Sciences2008，20，7： | 8 |
| 3 | Combined effect of boundary layer formation and surface smoothing on friction and wear rate of lubricated point contacts during normal running-in processes显示文摘The combined effect of boundary layer formation and surface smoothing on friction and wear rate of metallic surfaces under lubricated point contact condition was investigated. The double trend of friction coefficient variations was revealed during running-in and sub-running-in processes. The evolution of surface topography was measured on-site using white-light interference profilometer and analyzed using bearing area curves. Comprehensive theoretical equations that explicitly express the contributions of boundary friction, adhesive friction and wear have been derived, and results obtained by these equations were compared with experimental observations. It is concluded that the theoretical models are quantitatively adequate to describe the combined effect of surface smoothing due to mechanical wear and formation of boundary films on the changes in friction and wear rate during normal running-in processes. | Yazhao ZHANG Alexander KOVALEV Yonggang MENG | 2018 | Friction2018，6，3： | 4 |
| 4 | 生物再生生命保障系统设计的基本问题显示文摘生物再生生命保障系统(BLSS)是建立月球/火星基地,实现中长期载人空间飞行必须解决的关键技术。利用高等植物或微藻来生产食物、处理废物、再生O2和水是BLSS区别于其他类型生保系统的重要标志。BLSS在结构和功能上可以分为自养单元和异养单元两部分。本文简单绘制了三种不同的系统构型。在实际选择时,应根据任务需求选择系统综合质量最小的构型而不是单纯追求高封闭度。系统设计过程应遵循物质平衡的基本原则,尤其是与航天员生命息息相关的O2平衡和水平衡。 | 刘红 胡恩柱 胡大伟 Manukovsky N.S.

| 5 | Milliwatt terahertz harmonic generation from topological insulator metamaterials显示文摘Achieving effcient,high-power harmonic generation in the terahertz spectral domain has technological applications,for example,in sixth generation(6G)communication networks.Massless Dirac fermions possess extremely large terahertz nonlinear susceptibilities and harmonic conversion effciencies.However,the observed maximum generated harmonic power is limited,because of saturation effects at increasing incident powers,as shown recently for graphene.Here,we demonstrate room-temperature terahertz harmonic generation in a Bi_(2)Se_(3) topological insulator and topological-insulator-grating metamaterial structures with surface-selective terahertz field enhancement.We obtain a third-harmonic power approaching the miliwatt range for an incident power of 75 mW-an improvement by two orders of magnitude compared to a benchmarked graphene sample.We establish a framework in which this exceptional performance is the result of thermodynamic harmonic generation by the massless topological surface states,benefiting from ultrafast dissipation of electronic heat via surface-bulk Coulomb interactions.These results are an important step towards on-chip terahertz(opto)electronic applications. | Klaas-Jan Tielrooij Alessandro Principi David Saleta Reig Alexander Block Sebin Varghese Steffen Schreyeck Karl Brunner Grzegorz Karczewski Igor Ilyakov Oleksiy Ponomaryov Thales V.A.G.de Oliveira Min Chen Jan-Christoph Deinert Carmen Gomez Carbonell Sergio O.Valenzuela Laurens W.Molenkamp Tobias Kiessling Georgy V.Astakhov Sergey Kovalev | 2022 | Light(Science & Applications)2022，11，11： | 2 |
