| 1 | Growth of alumina oxide nanowires in an aluminum anodization process显示文摘Alumina oxide nanowires were grown via a two-step anodization of aluminum foil. A growth mechanism is proposed for these nanowires which is different from that of those formed using chemical etching methods. An electric field and stress are necessary to grow these nanowires, and the nano-imprinted metal surface of the aluminum foil has an important role. | ZHU KaiGui CHENG JingRan CHANG MingChao WANG Wu WEI WenBo GE GuangLu | 2011 | Chinese Science Bulletin2011，56，18： | 4 |
| 2 | Surface functionalization on the thermal conductivity of graphene-polymer nanocomposites显示文摘Exploring thermal transport in graphene-polymer nanocomposite is significant to its applications with better thermal properties.Interfacial thermal conductance between graphene and polymer matrix plays a critical role in the improvement of thermal conductivity of graphene-polymer nanocomposite.Unfortunately,it is still challenging to understand the interfacial thermal transport between graphene nanofiller and polymer matrix at small material length scale.To this end,using nonequilibrium molecular dynamics(NEMD)simulations,we investigate the interfacial thermal conductance of graphene-polyethylene(PE)nanocomposite.The influence of functionalization with hydrocarbon chains on the interfacial thermal conductance of graphene-polymer nanocomposites was studied,taking into account the effects of model size and thermal conductivity of graphene.An analytical model is also used to calculate the thermal conductivity of nanocomposite.The results are considered to contribute to the development of new graphene-polymer nanocomposites with tailored thermal properties. | Mingchao Wang Dilini Galpaya Zheng Bo Lai Yanan Xu Cheng Yan | 2014 | International Journal of Smart and Nano Materials2014，5，2： | 2 |
| 3 | On the technologies of Hα imaging spectrograph for the CHASE mission显示文摘The Hα imaging spectrograph(HIS) is the scientific payload of the first solar space mission, the Chinese Hα solar explorer(CHASE), supported by the China National Space Administration(CNSA). The CHASE/HIS achieves, for the first time in space, Hα spectroscopic observations with high spectral and temporal resolutions. Separate channels for the raster scanning mode(RSM) and continuum imaging mode(CIM) are integrated into one, and a highly integrated design is achieved through multiple folding of the optical path and ultra-light miniaturized components. The design of HIS implements a number of key technologies such as high-precision scanning of the optical field of view(FOV), high-precision integrated manufacturing inspection, a large-tolerance pre-filter window, and full-link solar radiation calibration. The HIS instrument has a pixel spectral resolution of 0.024 ? and can complete a full-Sun scanning within 46 s. | Qiang Liu Hongjiang Tao Changzheng Chen Chengshan Han Zhe Chen Gui Mei Liang Yang Qinglong Hu Hongwei Xin Xiansheng Li Hongyu Guan Donglin Xue Mingchao Zhu Changhong Hu Qinghua Ha Yukun He Cheng Fang Chuan Li Zhen Li | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 2 |
| 4 | Fluorescent detection of coenzyme A by analyte-induced aggregation of a cationic conjugated polymer显示文摘A new cationic conjugated polymer was designed and synthesized to optically discriminate coenzyme A(CoA) among structurally similar biomolecules, ATP, ADP and AMP. The analyte-induced aggregation of the conjugated polymer by π-stacking between their main chains leads to the fluorescence quenching. Except for the similar adenosine and phosphate moieties as those in ATP, ADP and AMP, the CoA molecule also includes a long side chain that is favorable for hydrophobic interactions. Thus, CoA can form a complex with oppositely charged conjugated polymer by cooperative electrostatic and hydrophobic interactions, whereas ATP, ADP and AMP form the complexes with oppositely charged conjugated polymer mainly by electrostatic interactions. The increase of the ion strength of the assay solution screens the electrostatic attractions, and the remaining hydrophobic interactions dominate the formation of PFP-PTF/CoA complex. At this case, the quenching efficiency of PFP-PTF by CoA is much higher than that by ATP, ADP and AMP, which impart the PFP-PTF to sense CoA from these interferencing species. | CHENG MingChao QIANG XiHuai DU ChiMin | 2013 | Chinese Science Bulletin2013，58，11： | 1 |
| 5 | Food-trade-associated COVID-19 outbreak from a contaminated wholesale food supermarket in Beijing显示文摘The re-emerging outbreak of COVID-19 in Beijing,China,in the summer of 2020 originated from a SARSCoV-2-infested wholesale food supermarket.We postulated that the Xinfadi market outbreak has links with food-trade activities.Our Susceptible to the disease,Infectious,and Recovered coupled Agent Based Modelling(SIR-ABM)analysis for studying the diffusion of SARS-CoV-2 particles suggested that the trade-distancing strategy effectively reduces the reproduction number(R0).The retail shop closure strategy reduced the number of visitors to the market by nearly half.In addition,the buy-local policy option reduced the infection by more than 70%in total.Therefore,retail closures and buy-local policies could serve as significantly effective strategies that have the potential to reduce the size of the outbreak and prevent probable outbreaks in the future. | Shan Lu Weijia Wang Yanpeng Cheng Caixin Yang Yifan Jiao Mingchao Xu Yibo Bai Jing Yang Hongbin Song Ligui Wang Jiaojiao Wang Bing Rong Jianguo Xu | 2021 | Journal of Biosafety and Biosecurity2021，3，1： | 0 |
