1Two-dimensional nanomaterials: fascinating materials in biomedical field显示文摘Due to their high anisotropy and chemical functions,two-dimensional(2D)nanomaterials have attracted increasing interest and attention from various scientific fields,including functional electronics,catalysis,supercapacitors,batteries and energy materials.In the biomedical field,2D nanomaterials have made significant contributions to the field of nanomedicine,especially in drug/gene delivery systems,multimodal imaging,biosensing,antimicrobial agents and tissue engineering.2D nanomaterials such as graphene/graphene oxide(GO)/reduced graphene oxide(r GO),silicate clays,layered double hydroxides(LDHs),transition metal dichalcogenides(TMDs),transition metal oxides(TMOs),black phosphorus(BP),graphitic carbon nitride(g-C3N4),hexagonal boron nitride(h-BN),antimonene(AM),boron nanosheets(B NSs)and tin telluride nanosheets(Sn Te NSs)possess excellent physical,chemical,optical and biological properties due to their uniform shapes,high surface-to-volume ratios and surface charge.In this review,we first introduce the properties,structures and synthetic strategies of different configurations of 2D nanomaterials.Recent advances and paradigms of 2D nanomaterials in a variety of biomedical applications,ranging from drug delivery,cancer treatment,bioimaging and tissue engineering to biosensing are discussed afterwards.In the final part,we foresee the development prospects and challenges of 2D nanomaterials after summarizing the research status of ultrathin 2D nanomaterials.Tingting Hu Xuan Mei Yingjie Wang Xisheng Weng Ruizheng Liang Min Wei 2019Science Bulletin2019,64,22:12
2Certificateless key-insulated signature without random oracles显示文摘Leakage of the private key has become a serious problem of menacing the cryptosystem security. To reduce the underlying danger induced by private key leakage, Dodis et al.(2003) proposed the first key-insulated signature scheme. To handle issues concerning the private key leakage in certificateless signature schemes, we devise the first certificateless key-insulated signature scheme. Our scheme applies the key-insulated mechanism to certificateless cryptography, one with neither certificate nor key escrow. We incorporate Waters (2005)’s signature scheme, Paterson and Schuldt (2006)’s identity-based signature scheme, and Liu et al.(2007)’s certificateless signature scheme to obtain a certificateless key-insulated signature scheme. Our scheme has two desirable properties. First, its security can be proved under the non-pairing-based generalized bilinear Diffie-Hellman (NGBDH) conjecture, without utilizing the random oracle model; second, it solves the key escrow problem in identity-based key-insulated signatures.Zhong-mei WAN Xue-jia LAI Jian WENG Sheng-li LIU Yu LONG Xuan HONG 2009Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009,10,12:6

4IDENTITY-BASED KEY-INSULATED PROXY SIGNATURE显示文摘In proxy signature schemes,the proxy signer B is permitted to produce a signature on behalf of the original signer A. However,exposure of proxy signing keys can be the most devastating attack on a proxy signature scheme since any adversary can sign messages on behalf of the proxy signer. In this paper,we applied Dodis,et al.’s key-insulation mechanism and proposed an Identity-Based (ID-based) Key-Insulated Proxy Signature (IBKIPS) scheme with secure key-updates. The proposed scheme is strong key-insulated and perfectly key-insulated. Our scheme also supports unbounded period numbers and random-access key-updates.Wan Zhongmei Lai Xuejia Weng Jian Liu Shengli Hong Xuan 2009Journal of Electronics(China)2009,26,6:4
5Theoretical Risk Assessment of Dietary Exposure to Advantame among the Chinese Population显示文摘Advantame,with the chemical name N-[N-[3-(3-hydroxy-4-methoxyphenyl)propyl]-α-aspartyl]L-phenylalanine 1-methyl ester,monohydrate,is an artificial sweetener made by a chemical reaction between vanillin and aspartame,which are both permitted as flavoring and food additives by the China National Food Safety Standard-Standards for Use of Food Additives(GB 2760).As an intense sweetener,advantame is approximately 90-120times sweeter than aspartame and approximately14,000-48,000 times sweeter than saccharose.ZHANG Ji Yue ZHANG Jian Bo YU Hang Yu YONG Ling ZHANG Hong WANG Hua Li WENG Yun Xuan 2019Biomedical and Environmental Sciences2019,32,12:3
6Reactive Adsorption of Thiophene on ZnNi/Diatomite-Pseudo-Boehmite Adsorbents显示文摘The thiophene removal ability of the synthesized ZnNi/diatomite-pseudo-boehmite adsorbent was tested in a labscale fixed-bed reaction system.X-ray diffractograms(XRD) were used to characterize the adsorbent samples.The effects of Zn/Ni molar ratio,various model fuels and regeneration patterns on the RADS tests were studied.The adsorption mechanism was investigated by XRD and MS analyses.The results indicted that thiophene in the model fuel was first decomposed on the surface Ni of the adsorbent to form Ni3S2 while the hydrocarbon portion of the molecule was released back into the process stream,followed by reduction of Ni3S2 to form H2S in the presence of H2,and then H2S is stored in the adsorbent accompanied by the conversion of ZnO into ZnS.Meng Xuan Weng Huixin Shi Li 2012China Petroleum Processing & Petrochemical Technology2012,14,3:2

14Building Bridges in a Third Space:A Phenomenological Study of the Lived Experiences of Teaching Chinese in American Chinese Schools显示文摘This study explores the lived experiences of Chinese teachers in American Chinese Schools.Max van Manen’s methodology for hermeneutic phenomenological research provides a framework for the study,and the philosophical writings of Heidegger,Gadamer,and Derrida guide the textual interpretations.Pedagogical voices of Aoki,Pinar,and Greene,and cultural journeys of Hongyu Wang and Xin Li reveal possibilities for understanding the experiences of Chinese teachers,as the question is addressed:“What is the meaning of teaching Chinese in American Chinese Schools?”Ten Chinese teachers engaged in a series of open-ended conversations.The conversations illuminate the experience of Confucian teaching meeting American pedagogies around two main themes.First,in following the metaphor of Chinese knotwork,the teachers speak of their struggles and challenges between Chinese Confucian and American pedagogies,reflect on splitting and splicing the knots through changing and adjusting their method of Confucian teaching.Second,they tell of the experiences of building bridges in a third space through dialogically connecting the different cultures and pedagogies in order to seek the appropriate way of teaching and learning Chinese well in American Chinese Schools.Xuan WENG Jing LIN 2013Frontiers of Education in China2013,8,1:0
15Traveling Waves for Nonlocal and Non-monotone Delayed Reaction-difusion Equations显示文摘We study the existence of traveling wave solutions for a nonlocal and non-monotone delayed reaction-difusion equation.Based on the construction of two associated auxiliary reaction difusion equations with monotonicity and by using the traveling wavefronts of the auxiliary equations,the existence of the positive traveling wave solutions for c≥c is obtained.Also,the exponential asymptotic behavior in the negative infnity was established.Moreover,we apply our results to some reactiondifusion equations with spatio-temporal delay to obtain the existence of traveling waves.These results cover,complement and/or improve some existing ones in the literature.Zhi Ting XU Pei Xuan WENG 2013Acta Mathematica Sinica,English Series2013,29,11:0
16Reactive Adsorption of Thiophene Using a NiZnO-Based Adsorbent显示文摘The thiophene removal ability of the synthesized NiZnO-based adsorbent was tested in a lab-scale fixed-bed system. The X-ray diffractometer (XRD) and the temperature-programmed reduction (H2-TPR) instrument were used to characterize the samples. The XRD and TPR results showed that there existed stronger synergetic effect between ZnO and NiO to form well-dispersed adsorbent particles when the Zn/Ni molar ratio in adsorbent was 0.4, and that the optimum temperature for reduction of the NiZnO-based adsorbent was approximately in the range of 350℃—400℃. In addition, the effects of reaction temperature, and reaction pressure on the reactive adsorption desulfurization tests were studied.Meng Xuan Weng Huixin Shi Li 2012China Petroleum Processing & Petrochemical Technology2012,14,4:0
17Impacts of the Urban Spatial Landscape in Beijing on Surface and Canopy Urban Heat Islands显示文摘How does the urban spatial landscape(USL)pattern affect the land surface urban heat islands(SUHIs)and canopy urban heat islands(CUHIs)?Based on satellite and meteorological observations,this case study compares the impacts of the USL pattern on SUHI and CUHI in the central urban area(CUA)of Beijing using the satellite land-surface-temperature product and hourly temperature data from automatic meteorological stations from 2009 to 2018.Eleven USL metrics—building height(BH),building density(BD),standard deviation of building height(BSD),floor area ratio(FAR),frontal area index(FAI),roughness length(RL),sky view factor(SVF),urban fractal dimension(FD),vegetation coverage(VC),impervious coverage(IC),and albedo(AB)—with a 500-m spatial resolution in the CUA are extracted for comparative analysis.The results show that SUHI is higher than CUHI at night,and SUHI is only consistent with CUHI at spatial-temporal scales at night,particularly in winter.Spatially,all 11 metrics are strongly correlated with both the SUHI and CUHI at night,with stronger correlation between most metrics and SUHI.VC,AB,and SVF have the greatest impact on both the SUHI and CUHI.High SUHI and CUHI values tend to appear in areas with BD≥0.26,VC≤0.09,AB≤0.09,and SVF≤0.67.In summer,most metrics have a greater impact on the SUHI than CUHI;the opposite is observed in winter.SUHI variation is affected primarily by VC in summer and by VC and AB in winter,which is different for the CUHI variation.The collective contribution of all 11metrics to SUHI spatial variation in summer(61.8%)is higher than that to CUHI;however,the opposite holds in winter and for the entire year,where the cumulative contribution of the factors accounts for 66.6%and 49.6%,respectively,of the SUHI variation.Yonghong LIU Yongming XU Yeping ZHANG Xiuzhen HAN Fuzhong WENG Chunyi XUAN Wenjun SHU 2022Journal of Meteorological Research2022,36,6:0
