| 1 | Enhanced localized and uniform corrosion resistances of bulk nanocrystalline 304 stainless steel in high-concentration hydrochloric acid solutions at room temperature显示文摘The localized and uniform corrosion resistances of bulk nanocrystalline 304 stainless steel(NC-304 SS)produced by severe rolling technique, and its conventional polycrystalline 304 stainless steel(CC-304 SS)counterpart, were investigated in high-concentration hydrochloric acid solutions at room temperature.NC-304 SS can scarcely suffer from localized corrosion in 4 mol/L and 5 mol/L HCl solutions during 5-day immersion tests, and in 1-3 mol/L HCl solutions during thirty-five-day immersion tests. The corrosion rate of NC-304 SS was also less than that of CC-304 SS during these immersion tests. The improved localized and uniform corrosion resistances of NC-304 SS were explained in terms of the adsorption and chemical activity of Cl^-on NC-304 SS and CC-304 SS characterized by X-ray photoelectron spectroscopy,and the valence electron configurations of NC-304 SS and CC-304 SS were characterized by ultra-violet photoelectron spectroscopy rather than conventional electrochemical results. | S.G.Wang M.Sun Y.H.Xu K.Long Z.D.Zhang | 2018 | Journal of Materials Science & Technology2018，34，12： | 4 |
| 2 | Adakite-like granitoids of Songkultau:A relic of juvenile Cambrian arc in Kyrgyz Tien Shan显示文摘The early Paleozoic Terskey Suture zone,located in the southern part of the Northern Tien Shan domain in Kyrgyzstan,comprises tectonic slivers of dismembered ophiolites and associated primitive volcanics and deepmarine sediments.In the Lake Songkul area,early-middle Cambrian pillow basalts are crosscut by the Songkultau intrusion of coarse-grained gneissose quartz diorites and tonalites with geochemical characteristics typical for high-SiO2 adakites(SiO2>56 wt.%,Al2O3>15 wt.%,Na2 O>3.5 wt.%and high Sr/Y and La/Yb ratios).The Songkultau granitoids have positive initialεNd(+3.8 to+6.4)andεHf(+12.3 to+13.5)values indicating derivation from sources with MORB-like isotopic signature.Volcanic formations,surrounding the Songkultau intrusion,have geochemical affinities varying from ocean floor to island arc series.This rock assemblage is interpreted as a relic of an early-middle Cambrian primitive arc where the adakite-like granitoids were derived from partial melting of young and hot subducted oceanic crust.An age of 505 Ma,obtained for the Songkultau intrusion,shows that hot subduction under the Northern Tien Shan continued until middle Cambrian.The primitive arc complexes were obducted onto the Northern Tien Shan domain,where the Andean type continental magmatic arc developed in Cambrian and Ordovician.Formation of the Andean type arc was accompanied by uplift,erosion and deposition of coarse clastic sediments.A depositional age of ca.470 Ma,obtained for the gravellites in the Lake Songkul area,is in agreement with the timing of deposition for lower Ordovician conglomerates elsewhere in the Northern Tien Shan,and corresponds to the main phase of the Andean type magmatism.The Songkultau adakites in association with surrounding ocean floor and island arc formations constitute a relic of a primitive Cambrian arc and represent a juvenile domain of substantial size identified so far within the predominantly crustal-derived terranes of Tien Shan.On a regional scale this primitive arc can be compared with juvenile Cambrian arcs of Kazakhstan,Gorny Altai and Mongolia. | D.Konopelko R.Seltmann A.Dolgopolova I.Safonova S.Glorie J.De Grave M.Sun | 2021 | Geoscience Frontiers2021，12，1： | 1 |

| 5 | Application of lung microphysiological systems to COVID-19 modeling and drug discovery:a review显示文摘There is a pressing need for effective therapeutics for coronavirus disease 2019(COVID-19),the respiratory disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)virus.The process of drug development is a costly and meticulously paced process,where progress is often hindered by the failure of initially promising leads.To aid this chal-lenge,in vitro human microphysiological systems need to be refined and adapted for mechanistic studies and drug screening,thereby saving valuable time and resources during a pandemic crisis.The SARS-CoV-2 virus attacks the lung,an organ where the unique three-dimensional(3D)structure of its functional units is critical for proper respiratory function.The in vitro lung models essentially recapitulate the distinct tissue structure and the dynamic mechanical and biological interactions between different cell types.Current model systems include Transwell,organoid and organ-on-a-chip or microphysiological systems(MPSs).We review models that have direct relevance toward modeling the pathology of COVID-19,including the processes of inflammation,edema,coagulation,as well as lung immune function.We also consider the practical issues that may influence the design and fabrication of MPS.The role of lung MPS is addressed in the context of multi-organ models,and it is discussed how high-throughput screening and artificial intelligence can be integrated with lung MPS to accelerate drug development for COVID-19 and other infectious diseases. | Argus M.Sun Tyler Hoffman Bao Q.Luu Nureddin Ashammakhi Song Li | 2021 | Bio-Design and Manufacturing2021，4，4： | 0 |
