2Advances in direct production of value-added chemicals via syngas conversion显示文摘Syngas conversion to fuels and chemicals is one of the most challenging subjects in the field of C1 chemistry. It is considered as an attractive alternative non-petroleum-based production route. The direct synthesis of olefins and alcohols as high value-added chemicals from syngas has drawn particular attention due to its process simplicity, low energy consumption and clean utilization of carbon resource, which conforms to the principles of green carbon science. This review describes the recent advances for the direct production of lower olefins and higher alcohols via syngas conversion. Recent progress in the development of new catalyst systems for enhanced catalytic performance is highlighted. We also give recommendations regarding major challenges for further research in syngas conversion to various chemicals.Yunlei An Tiejun Lin Fei Yu Yanzhang Yang Liangshu Zhong Minghong Wu Yuhan Sun 2017Science China Chemistry2017,60,7:8
3An overview on nonlinear porous flow in low permeability porous media显示文摘This paper gives an overview on nonlinear porous flow in low permeability porous media, reveals the microscopic mechanisms of flows, and clarifies properties of porous flow fluids. It shows that, deviating from Darcy's linear law, the porous flow characteristics obey a nonlinear law in a low-permeability porous medium, and the viscosity of the porous flow fluid and the permeability values of water and oil are not constants. Based on these characters, a new porous flow model, which can better describe low permeability reservoir, is established. This model can describe various patterns of porous flow, as Darcy's linear law does. All the parameters involved in the model, having definite physical meanings, can be obtained directly from the experiments.Yanzhang Huang Zhengming Yang Ying He Xuewu Wang 2013Theoretical & Applied Mechanics Letters2013,3,2:3
4Cloning, identification, and expression analysis at the stage of gonadal sex differentiation of chicken miR-363 and 363显示文摘miRNAs (microRNAs ) 是小的,功能的、非编码的 RNA 并且被证明了在从房间区别到有机体开发的多样的生物过程的规定含有。以达到在鸡胚胎上探索 miRNAs 的角色性决心和 gonadal 区别,我们克隆并且识别茎环先锋结构( GenBank 同意没有 GU597370 )鸡肉, miR-363 和363*由在 E3.56.5 d 的阶段在鸡胚胎学习他们的时间、空间的表示模式列在后面(胚胎的天 3.56.5 )由半量的 RT-PCR 和愿望(在 situ 杂交整个山)在这研究。结果显示出那 miR-363 * 根据 miRNAs 的结构的特征在 miR-363 和 363* 的鸡染色体,和 flanking 顺序在未知片断的克隆的顺序定位了先锋。显著地微分的表示(P < 0.05 ) 在雌、雄的鸡肉之间的 gga-miR-363,胚胎的性腺被发现在 E4.5 和 6.5 d,而是 gga-miR-363 的微分表示 * 从 E3.5,到 6.5,在两性之间的 d 达不到重要水平。那个表达式 gga-miR-363 表明的显示的愿望的结果主要在 E6.5 出现在手足芽,脊索,外胚层,在 E4.5 d 鸡胚胎的大脑,和尿生殖的系统(UGS ) d,和 E6.5 d 的表达式水平在男性比那在女性是更高的。gga-miR-363 将在 gonadal 发展和 gga-miR-363 包含,这能被推测 * 可能在鸡胚胎开发的早阶段期间有短暂规章的功能。Pan Huang Yanzhang Gong Xiuli Peng ShijunLi Yu Yang Yanping Feng 2010Acta Biochimica et Biophysica Sinica2010,42,8:2
5Infuence of the Shallow Heterogeneities to the TEM Response of the Large Fixed Loop 显示文摘Wang Yanzhang Yang Mengmeng Fu Lei 2014Journal of Jilin University (Earth Sciences Edition)2014,44,2:1
6Effect of Sodium on the Structure-Performance Relationship of Co/SiO2 for Fischer-Tropsch Synthesis显示文摘有不同的钠(Na ) 的一系列 Co/SiO 2 催化剂装载(0, 0.1, 0.2, 0.5 并且 1wt%) 被准备并且评估了让 Fischer-Tropsch 反应在催化剂结构和催化性能上学习 Na 的效果。Na 的增加被发现催化活动和烃选择到减少,但是由于提高的 WGS 活动增加公司 2 选择。Na 的增加也导致了更高的选择到氧化(白酒和醛) 并且 O/P 比率以及到更低的碳的烃的移动数。结构描述与 Na 的增加为锻烧的样品在表面区域和粒子尺寸揭示了减少。公司 2 C 为支持 Na 的催化剂在反应过程期间被形成。作为结果,新公司 / 公司 2 C bifunctional 活跃地点被产生为氧化形成导致增加氧化选择。另外,公司 2 C nanoparticles 可以也独自充当双活跃地点为氧化在在有装载的高 Na 的支持的催化剂上的高反应压力的形成。Yuanyuan Dai Fei Yu Zhengjia Li Yunlei An Tiejun Lin Yanzhang Yang Liangshu Zhong Hui wang Yuhan Sun 2017Chinese Journal of Chemistry2017,35,6:1
7Phosphorylation of MtRopGEF2 by LYK3 mediates MtROP activity to regulate rhizobial infection in Medicago truncatula显示文摘The formation of nitrogen-fixing no dules on legume roots requires the coordination of infection by rhizobia at the root epidermis with the initiation of cell divisions in the root cortex.During infection,rhizobia attach to the tip of elongating root hairs which then curl to entrap the rhizobia.However,the mechanism of root hair deformation and curling in response to symbiotic signals is still elusive.Here,we found that small GTPases(MtRac1/MtROP9 and its homologs)are required for root hair development and rhizobial infection in Medicago truncatula.Our results show that the Nod factor receptor LYK3 phosphorylates the guanine nucleotide exchange factor MtRopGEF2 at S73 which is critical for the polar growth of root hairs.In turn,phosphorylated MtRopGEF2 can activate MtRac1.Activated MtRac1 was found to localize at the tips of root hairs and to strongly interact with LYK3 and NFP.Taken together,our results support the hypothesis that MtRac1,LYK3,and NFP form a polarly localized receptor complex that regulates root hair deformation during rhizobial infection.Mingxing Wang Huan Feng Peng Xu Qiujin Xie Jinpeng Gao Yanzhang Wang Xiaowei Zhang Jun Yang Jeremy DMurray Fengli Sun Chunyan Wang Ertao Wang Nan Yu 2021Journal of Integrative Plant Biology2021,63,10:0
