| 1 | 两气门多缸柴油机进气道和缸内气流数值模拟研究显示文摘搭载柴油机的小型、紧凑型车辆中,每缸两气门设计的柴油机仍然占有相当大的市场份额。论述了对1台1.2L每缸两气门柴油机中气道-气门-缸内气流的数值模拟研究,以描述其进气歧管和进气道的性能。首先,确定了对多缸发动机进气歧管性能进行计算流体力学(CFD)评估的评价指标并建立了分析程序。然后对照基准型四气门发动机进行了两气门发动机的CFD分析。结果表明,在两气门发动机中,发现在上止点附近存在着进气道和流量分布之间的复杂相互作用,导致了在气道进口处比基准四气门发动机更高的平均流速、不均匀性指数/旋转动量,以及更高的涡流比,从而可能导致高负荷工况下的高烟度。CFD模拟表明,具有较大容积和更长流道的高容量进气歧管有助于改善两气门发动机的流量均匀性,以及缸与缸之间的流量变化,其对发动机扭矩和排放的改善已通过多缸发动机试验得到了验证。 | J.Gao G.Cuneo 陈晓峰(译) 程玉发(译) | 2018 | 汽车与新动力2018，1，5： | 3 |

| 8 | Remote substituent effects on catalytic activity of metal-organic frameworks: a linker orbital energy model显示文摘The Hammett equation is commonly used to theoretically depict the remote electronic effects of substituents on catalytic activitiesof metal nodes of metal-organic frameworks (MOFs). However, the application of the theory to MOF catalysts usually encountersproblems because it relies heavily on empirical parameters with unknown transferability. To develop an alternative predictiontheory, the linker orbital energy model has been proposed by density functional theory calculations. The model provides a simplemethod to approximately depict the remote electronic substituent effects on catalytic activities of metal nodes of MOFs, and itsgeneral applicability to MOFs is supported by extensively revisiting the structure-activity relationships reported in the literatures.The model can be used to design catalytic activity of metal nodes of MOFs by engineering the electronic properties of linkers andsubstituents. | Zhenzhen Wang Huan Meng Xuejiao J.Gao Jia-Jia Zheng Xingfa Gao | 2023 | npj Computational Materials2023，，1： | 1 |

| 17 | Site-Specific Conjugation of Cell Wall Polyrhamnose to Protein SpyAD Envisioning a Safe Universal Group A Streptococcal Vaccine显示文摘Development of an effective vaccine against the leading human bacterial pathogen group A Streptococcus(GAS)is a public health priority.The species defining group A cell wall carbohydrate(GAC,Lancefield antigen)can be engineered to remove its immunodominant N-acetylglucosamine(GlcNAc)side chain,implicated in provoking autoimmune cross-reactivity in rheumatic heart disease,leaving its polyrhamnose core(GACPR).Here we generate a novel protein conjugate of the GACPR and test the utility of this conjugate antigen in active immunization.Instead of conjugation to a standard carrier protein,we selected SpyAD,a highly conserved GAS surface protein containing both B-cell and T-cell epitopes relevant to the bacterium that itself shows promise as a vaccine antigen.SpyAD was synthesized using the XpressTM cell-free protein expression system,incorporating a non-natural amino acid to which GACpr was conjugated by site-specific click chemistry to yield high molecular mass SpyAD-GACPR conjugates and avoid disruption of important T-cell and B-cell immunological epitopes.The conjugated SpyAD-GACPR elicited antibodies that bound the surface of multiple GAS strains of diverse M types and promoted opsonophagocytic killing by human neutrophils.Active immunization of mice with a multivalent vaccine consisting of SpyAD-GACPR,together with candidate vaccine antigens streptolysin O and C5a peptidase,protected against GAS challenge in a systemic infection model and localized skin infection model,without evidence of cross reactivity to human heart or brain tissue epitopes.This general approach may allow GAC to be safely and effectively included in future GAS subunit vaccine formulations with the goal of broad protection without autoreactivity. | Nina J.Gao Satoshi Uchiyama Lucy Pill Samira Dahesh Joshua Olson Leslie Bautista Shilpa Maroju Aym Berges Janet ZLiu Raymond HZurich Nina Mvan Sorge Jeff Fairman Neeraj Kapoor Victor Nizet | 2021 | Infectious Microbes & Diseases2021，3，2： | 0 |
| 18 | STCF conceptual design report (Volume 1): Physics & detector显示文摘The superτ-charm facility(STCF)is an electron–positron collider proposed by the Chinese particle physics community.It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of 0.5×1035 cm–2·s–1 or higher.The STCF will produce a data sample about a factor of 100 larger than that of the presentτ-charm factory—the BEPCII,providing a unique platform for exploring the asymmetry of matter-antimatter(charge-parity violation),in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions,as well as searching for exotic hadrons and physics beyond the Standard Model.The STCF project in China is under development with an extensive R&D program.This document presents the physics opportunities at the STCF,describes conceptual designs of the STCF detector system,and discusses future plans for detector R&D and physics case studies. | M.Achasov X.C.Ai L.P.An R.Aliberti Q.An X.Z.Bai Y.Bai O.Bakina A.Barnyakov V.Blinov V.Bobrovnikov D.Bodrov A.Bogomyagkov A.Bondar I.Boyko Z.H.Bu F.M.Cai H.Cai J.J.Cao Q.H.Cao X.Cao Z.Cao Q.Chang K.T.Chao D.Y.Chen H.Chen H.X.Chen J.F.Chen K.Chen L.L.Chen P.Chen S.L.Chen S.M.Chen S.Chen S.P.Chen W.Chen X.Chen X.F.Chen X.R.Chen Y.Chen Y.Q.Chen H.Y.Cheng J.Cheng S.Cheng T.G.Cheng J.P.Dai L.Y.Dai X.C.Dai D.Dedovich A.Denig I.Denisenko J.M.Dias D.Z.Ding L.Y.Dong W.H.Dong V.Druzhinin D.S.Du Y.J.Du Z.G.Du L.M.Duan D.Epifanov Y.L.Fan S.S.Fang Z.J.Fang G.Fedotovich C.Q.Feng X.Feng Y.T.Feng J.L.Fu J.Gao Y.N.Gao P.S.Ge C.Q.Geng L.S.Geng A.Gilman L.Gong T.Gong B.Gou W.Gradl J.L.Gu A.Guevara L.C.Gui A.Q.Guo F.K.Guo J.C.Guo J.Guo Y.P.Guo Z.H.Guo A.Guskov K.L.Han L.Han M.Han X.Q.Hao J.B.He S.Q.He X.G.He Y.L.He Z.B.He Z.X.Heng B.L.Hou T.J.Hou Y.R.Hou C.Y.Hu H.M.Hu K.Hu R.J.Hu W.H.Hu X.H.Hu Y.C.Hu J.Hua G.S.Huang J.S.Huang M.Huang Q.Y.Huang W.Q.Huang X.T.Huang X.J.Huang Y.B.Huang Y.S.Huang N.Hüsken V.Ivanov Q.P.Ji J.J.Jia S.Jia Z.K.Jia H.B.Jiang J.Jiang S.Z.Jiang J.B.Jiao Z.Jiao H.J.Jing X.L.Kang X.S.Kang B.C.Ke M.Kenzie A.Khoukaz I.Koop E.Kravchenko A.Kuzmin Y.Lei E.Levichev C.H.Li C.Li D.Y.Li F.Li G.Li G.Li H.B.Li H.Li H.N.Li H.J.Li H.L.Li J.M.Li J.Li L.Li L.Li L.Y.Li N.Li P.R.Li R.H.Li S.Li T.Li W.J.Li X.Li X.H.Li X.Q.Li X.H.Li Y.Li Y.Y.Li Z.J.Li H.Liang J.H.Liang Y.T.Liang G.R.Liao L.Z.Liao Y.Liao C.X.Lin D.X.Lin X.S.Lin B.J.Liu C.W.Liu D.Liu F.Liu G.M.Liu H.B.Liu J.Liu J.J.Liu J.B.Liu K.Liu K.Y.Liu K.Liu L.Liu Q.Liu S.B.Liu T.Liu X.Liu Y.W.Liu Y.Liu Y.L.Liu Z.Q.Liu Z.Y.Liu Z.W.Liu I.Logashenko Y.Long C.G.Lu J.X.Lu N.Lu Q.F.Lü Y.Lu Y.Lu Z.Lu P.Lukin F.J.Luo T.Luo X.F.Luo Y.H.Luo H.J.Lyu X.R.Lyu J.P.Ma P.Ma Y.Ma Y.M.Ma F.Maas S.Malde D.Matvienko Z.X.Meng R.Mitchell A.Nefediev Y.Nefedov S.L.Olsen Q.Ouyang P.Pakhlov G.Pakhlova X.Pan Y.Pan E.Passemar Y.P.Pei H.P.Peng L.Peng X.Y.Peng X.J.Peng K.Peters S.Pivovarov E.Pyata B.B.Qi Y.Q.Qi W.B.Qian Y.Qian C.F.Qiao J.J.Qin J.J.Qin L.Q.Qin X.S.Qin T.L.Qiu J.Rademacker C.F.Redmer H.Y.Sang M.Saur W.Shan X.Y.Shan L.L.Shang M.Shao L.Shekhtman C.P.Shen J.M.Shen Z.T.Shen H.C.Shi X.D.Shi B.Shwartz A.Sokolov J.J.Song W.M.Song Y.Song Y.X.Song A.Sukharev J.F.Sun L.Sun X.M.Sun Y.J.Sun Z.P.Sun J.Tang S.S.Tang Z.B.Tang C.H.Tian J.S.Tian Y.Tian Y.Tikhonov K.Todyshev T.Uglov V.Vorobyev B.D.Wan B.L.Wang B.Wang D.Y.Wang G.Y.Wang G.L.Wang H.L.Wang J.Wang J.H.Wang J.C.Wang M.L.Wang R.Wang R.Wang S.B.Wang W.Wang W.P.Wang X.C.Wang X.D.Wang X.L.Wang X.L.Wang X.P.Wang X.F.Wang Y.D.Wang Y.P.Wang Y.Q.Wang Y.L.Wang Y.G.Wang Z.Y.Wang Z.Y.Wang Z.L.Wang Z.G.Wang D.H.Wei X.L.Wei X.M.Wei Q.G.Wen X.J.Wen G.Wilkinson B.Wu J.J.Wu L.Wu P.Wu T.W.Wu Y.S.Wu L.Xia T.Xiang C.W.Xiao D.Xiao M.Xiao K.P.Xie Y.H.Xie Y.Xing Z.Z.Xing X.N.Xiong F.R.Xu J.Xu L.L.Xu Q.N.Xu X.C.Xu X.P.Xu Y.C.Xu Y.P.Xu Y.Xu Z.Z.Xu D.W.Xuan F.F.Xue L.Yan M.J.Yan W.B.Yan W.C.Yan X.S.Yan B.F.Yang C.Yang H.J.Yang H.R.Yang H.T.Yang J.F.Yang S.L.Yang Y.D.Yang Y.H.Yang Y.S.Yang Y.L.Yang Z.W.Yang Z.Y.Yang D.L.Yao H.Yin X.H.Yin N.Yokozaki S.Y.You Z.Y.You C.X.Yu F.S.Yu G.L.Yu H.L.Yu J.S.Yu J.Q.Yu L.Yuan X.B.Yuan Z.Y.Yuan Y.F.Yue M.Zeng S.Zeng A.L.Zhang B.W.Zhang G.Y.Zhang G.Q.Zhang H.J.Zhang H.B.Zhang J.Y.Zhang J.L.Zhang J.Zhang L.Zhang L.M.Zhang Q.A.Zhang R.Zhang S.L.Zhang T.Zhang X.Zhang Y.Zhang Y.J.Zhang Y.X.Zhang Y.T.Zhang Y.F.Zhang Y.C.Zhang Y.Zhang Y.Zhang Y.M.Zhang Y.L.Zhang Z.H.Zhang Z.Y.Zhang Z.Y.Zhang H.Y.Zhao J.Zhao L.Zhao M.G.Zhao Q.Zhao R.G.Zhao R.P.Zhao Y.X.Zhao Z.G.Zhao Z.X.Zhao A.Zhemchugov B.Zheng L.Zheng Q.B.Zheng R.Zheng Y.H.Zheng X.H.Zhong H.J.Zhou H.Q.Zhou H.Zhou S.H.Zhou X.Zhou X.K.Zhou X.P.Zhou X.R.Zhou Y.L.Zhou Y.Zhou Y.X.Zhou Z.Y.Zhou J.Y.Zhu K.Zhu R.D.Zhu R.L.Zhu S.H.Zhu Y.C.Zhu Z.A.Zhu V.Zhukova V.Zhulanov B.S.Zou Y.B.Zuo | 2024 | Frontiers of physics2024，19，1： | 0 |
| 19 | Developing a Knock Predictive Criterion in Spark Ignition Engines Fuelled with Gaseous Fuels显示文摘Consideration of the chemical reaction activity of the end gas in a spark ignition and operating conditions are combined to predict the onset of knock and associated performance in an engine fuelled with methane.A two-zone predictive combustion model was developed based on an estimate of the effective duration of the combustion period and the mass burning rate for any set of operating conditions.The unburned end gas preignition chemical reaction activity is described by a detailed chemical reaction kinetic scheme for methane and air,The variation with time of the value of a formulated dimensionless knock parameter(k)is calcuated.It is shown that whenever knocking is encounteren.the value of “k” builds up to a sufficiently high value that exceeds a critical value.Under normal operating conditions,the value of “k” remains throughout the whole combustion period at comparatively very low levels.It is shown that the model and the use of this knock criterion“k” produce results that are in good agreement with experiment. | G.A.Karim J.Gao | 1993 | Journal of Thermal Science1993，2，4： | 0 |
| 20 | Largeπ-conjugated indium-based metal-organic frameworks for high‐performance electrochemical conversion of CO_(2)显示文摘The active site engineering of electrocatalysts,as one of the most economical and technological approaches,is a promising strategy to enhance the intrinsic activity and selectivity towards electrochemical CO_(2)reduction reaction.Herein,an indium-based porphyrin framework(In-TCPP)with a well-defined structure,highly dispersed catalytic center,and good stability was constructed for efficient CO_(2)-to-formate conversion.In-TCPP could achieve a high Faraday efficiency for formate(90%)and a cathodic energy efficiency of 63.8%in flow cells.In situ attenuated total reflectance Fourier transform infrared spectroscopy and density functional theory calculation confirm that the crucial intermediate is*COOH species which contributes to the formation of formate.This work is expected to provide novel insights into the precise design of active sites for high-performance electrocatalysts towards electrochemical CO_(2)reduction reaction. | Zengqiang Gao Yue Gong Yating Zhu Junjie Li Li Li Yongxia Shi Man Hou Xuejiao J.Gao Zhicheng Zhang Wenping Hu | 2023 | Nano Research2023，16，7： | 0 |
