| 1 | Microstructure and Tribological Behavior of Self-lubricating(Si:N)-DLC/MAO Coatings on AZ80 Magnesium Substrate显示文摘The combined micro arc oxidation(MAO)and a hybrid beam deposition process was used to deposit duplex(Si:N)-DLC/MAO coatings on AZ80 magnesium alloy.The microstructure and composition of the duplex coatings were analyzed by Raman spectroscopy,X-ray photoelectron spectroscope(XPS),scanning electron microscope(SEM)and atomic force microscopy(AFM).Tribological behaviors of the coatings were studied by ball-on-disk friction test.It was found that the ID/IG ratio of the(Si:N)-DLC(diamond-like carbon)top films increases with decreasing C2H2/N2ratio.The(Si:N)-DLC top film with Si3N4was formed on the MAO coated sample as the C2H2/N2ratio was 10sccm:5sccm,which showed an increasing critical load compared with the pure DLC directly deposited on the Mg alloy substrate.As a result,the(Si:N)-DLC/MAO coating exhibited an advanced wear protection for the substrate. | Wei YANG Zhennan DENG Dong ZHANG Peiling KE Aiying WANG | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，6： | 2 |

| 3 | Insights on high temperature friction mechanism of multilayer ta-C films显示文摘In this work,the high temperature friction mechanism of the tetrahedral amorphous carbon(ta-C)film was elucidated.The multilayer ta-C film with alternating hard and soft sub-layers exhibited a low friction coefficient of 0.14 at 400℃ before a sudden failure occurred at 4600 cycles.The wear failure was attributed to the gradual consumption of the ta-C film at the contact region.The design of a hard or soft top layer effectively regulated the high temperature friction properties of the multilayer ta-C.The addition of a hard top layer contributed to a low friction coefficient(0.11)and a minor wear rate(4.0×10^(-7)mm^(3)/(N m)),while a soft top layer deteriorated the lubrication effect.It was proposed that the passivation of dangling bonds at the sliding interface dominated the low-friction mechanism of the ta-C film at high temperature,while the friction induced graphitization and the formation of sp^(2)-rich carbonaceous transfer layer triggered C-C inter-film bonding,resulting in serious adhesion force and lubrication failure.Moreover,the multilayer ta-C film with hard top layer obtained excellent friction performance within 500℃,while the high temperature induced oxidation and volatilization of carbon atoms led to the wear failure at 600℃. | Jing Wei Peng Guo Hao Li Peiling Ke Aiying Wang | 2022 | Journal of Materials Science & Technology2022，，2： | 2 |
| 4 | Scalable carbon black deposited fabric/hydrogel composites for affordable solar-driven water purification显示文摘Interfacial solar-driven evaporators have presented great potential for water purification owing to their low energy consumption and high steam generation efficiency. However, their further applications are hindered by the high costs and complicated fabrication processes. Here, a scalable bilayer interfacial evaporator was constructed via an affordable technique, in which carbon black deposited nonwoven fabric(CB@NF) was employed as the upper photothermal layer, as well as PVA/starch hybrid hydrogel for selffloating and water transport. Under simulated one sun irradiation, CB@NF layer displayed excellent photothermal conversion performance, whose temperature could increase 30.4 ℃ within 15 min. Moreover,the introduction of starch into PVA endowed the hybrid hydrogels with considerable water-absorption capability on the premise of ensuring mechanical properties. The resultant CB@NF/PVA/starch composites achieved superior interfacial adhesion performance with interfacial toughness at about 200 J m.Combining with good evaporation performance, salt-rejection property and high purification efficiency on pollutants, this evaporation system would become a promising candidate to alleviate water shortage. | Ying Guo Congqi Li Peiling Wei Kai Hou Meifang Zhu | 2022 | Journal of Materials Science & Technology2022，，11： | 1 |

| 8 | Immune‑Ageing Evaluation of Peripheral T and NK Lymphocyte Subsets in Chinese Healthy Adults显示文摘Ageing is often accompanied with a decline in immune system function,resulting in immune ageing.Numerous studies have focussed on the changes in different lymphocyte subsets in diseases and immunosenescence.The change in immune phenotype is a key indication of the diseased or healthy status.However,the changes in lymphocyte number and phenotype brought about by ageing have not been comprehensively analysed.Here,we analysed T and natural killer(NK)cell subsets,the phenotype and cell differentiation states in 43,096 healthy individuals,aged 20–88 years,without known diseases.Thirty-six immune parameters were analysed and the reference ranges of these subsets were established in different age groups divided into 5-year intervals.The data were subjected to random forest machine learning for immune-ageing modelling and confirmed using the neural network analysis.Our initial analysis and machine modelling prediction showed that na.ve T cells decreased with ageing,whereas central memory T cells(Tcm)and effector memory T cells(Tem)increased cluster of differentiation(CD)28-associated T cells.This is the largest study to investigate the correlation between age and immune cell function in a Chinese population,and provides insightful differences,suggesting that healthy adults might be considerably influenced by age and sex.The age of a person's immune system might be different from their chronological age.Our immune-ageing modelling study is one of the largest studies to provide insights into‘immune-age’rather than‘biological-age’.Through machine learning,we identified immune factors influencing the most through ageing and built a model for immune-ageing prediction.Our research not only reveals the impact of age on immune parameter differences within the Chinese population,but also provides new insights for monitoring and preventing some diseases in clinical practice. | Zhenghu Jia Zhiyao Ren Dongmei Ye Jiawei Li Yan Xu Hui Liu Ziyu Meng Chengmao Yang Xiaqi Chen Xinru Mao Xueli Luo Zhe Yang Lina Ma Anyi Deng Yafang Li Bingyu Han Junping Wei Chongcheng Huang Zheng Xiang Guobing Chen Peiling Li Juan Ouyang Peisong Chen Oscar Junhong Luo Yifang Gao Zhinan Yin | 2023 | Phenomics2023，3，4： | 1 |
| 9 | Long-term tribocorrosion resistance and failure tolerance of multilayer carbon-based coatings显示文摘Current tribocorrosion research of metallic materials and their surface protective coatings mainly focuses on their short-term properties,with test time of 0.5‒2.0 h and a sliding distance 50‒500 m,which may significantly deviate from the practical long-term service condition and thus cause a catastrophe of marine equipments.In this study,three carbon-based multilayer coatings(Ti/DLC,TiC_(x)/DLC,and Ti‒TiC_(x)/DLC)were deposited on S32750 substrates,and both short-term and long-term tribocorrosion behaviors were investigated.The experimental results indicate that the coatings substantially improve the tribocorrosion resistance of the S32750 stainless steel.During the short-term tribocorrosion test,TiC_(x)/DLC exhibited the best tribocorrosion resistance owing to its high hardness.During the long-term tribocorrosion test,however,Ti‒TiC_(x)/DLC coating indicated the best anti-tribocorrosion performance owing to its excellent fracture toughness together with high hardness.Moreover,under 5 N,Ti‒TiC_(x)/DLC can withstand a long-term test of more than 24 h.Additionally,under a higher load of 20 N,the Ti‒TiC_(x)/DLC with a corresponding sliding distance of approximately 1,728 m maintained a low friction coefficient of approximately 0.06.However,the coating was completely worn out;this is attributable to the formation of tribocorrosion products consisting of graphitized carbon and nanocrystalline Fe_(x)O_(y). | Hao LI Linlin LIU Peng GUO Lili SUN Jing WEI Yingrui LIU Shuyu LI Shuyuan WANG Kwang-Ryeol LEE Peiling KE Aiying WANG | 2022 | Friction2022，10，10： | 1 |
| 10 | The chemical reprogramming of unipotent adult germ cells towards authentic pluripotency and de novo establishment of imprinting显示文摘Although somatic cells can be reprogrammed to pluripotent stem cells(PsCs)with pure chemicals,authentic pluripotency of chemically induced pluripotent stem celis(CipsCs)has never been achieved through tetraploid complementation assay.Spontaneous reprogramming of spermatogonial stem cells(ssCs)was another non-transgenic way to obtain PsCs,but this process lacks mechanistic explanation.Here,we reconstructed the trajectory of mouse SsC reprogramming and developed a five-chemical combination,boosting the reprogramming effciency by nearly 80-to 100-folds.More importantly,chemical induced germline-derived PsCs(5C-gPSCs),but not gpsCs and chemical induced pluripotent stem cells,had authentic pluripotency,as determined by tetraploid complementation.Mechanistically,ssCs traversed through an inverted pathway of in vivo germ ceil development,exhibiting the expression signatures and DNA methylation dynamics from spermatogonia to primordial germ cells and further to epiblasts.Besides,ssC-specific imprinting control regions switched from biallelic methylated states to monoallelic methylated states by imprinting demethylation and then re-methylation on one of the two alleles in 5c-gPsCs,which was apparently distinct with the imprinting reprogramming in vivo as DNA methylation simultaneously occurred on both alleles.Our work sheds ight on the unique regulatory network underpinning SsC reprogramming,providing insights to understand generic mechanisms for cell-fate decision and epigenetic-relateddisorders in regenerative medicine. | Yuhan Chen Jiansen Lu Yanwen Xu Yaping Huang Dazhuang Wang Peiling Liang Shaofang Ren Xuesong Hu Yewen Qin Wei Ke Ralf Jauch Andrew Paul Hutchins Mei Wang Fuchou Tang Xiao-Yang Zhao | 2023 | Protein & Cell2023，14，7： | 0 |
