Ignition delay of syngas is an important factor that affects stable operation of combustor and adding diluents to syngas can reduce NO_x *** paper used H_2O,CO_2 and N_2 as diluents and calculated ignition delay of syngas in temperature range of 900-1400 K and at pressures of 10 and 30 atm *** high temperature range,comparing with N_2 dilution,adding H_2O and CO_2 can significantly inhibit autoignition of syngas because they have higher collision efficiencies in reaction H + O_2(+ M) = HO_2(+ M).As for low temperature conditions,adding H_2O can increase reactivity of syngas,especially under high pressure,because of its high collision efficiency in reaction H_2O_2(+ M) = 2OH(+ M).Comparing with different dilution rates shows that for syngas and operating conditions in this paper,adding N_2 mainly influences temperature rising process of syngas combustion,thus inhibiting reactivity of *** addition,this paper calculated ignition delay of syngas at different equivalence ratios(φ= 0.5,1.0).Higher equivalence ratio(φ≤1) means that less air(especially N_2) needs to be heated,thus promoting ignition of syngas,

Nano Research 2018年第10期11卷 5240-5257页

作者： Teng Li he dong Can Zhang Ran Mo State Key Laboratory of Natural Medicines Jiangsu Key Laboratory of Drug Discovery for Metabolic Diseases Center of AdvancedPharmaceuticals and 8iomaterials China Pharmaceutical University Nanjing 210009 China

Spurred by numerous achievements in nanoscience and nanotechnology, the evolution of nanoparticulate drug delivery systems （nano-DDSs） is in its rapid growth period and attracting considerable attention due to their unique advantages in biomedical applications. Natural particulates ranging from mammalian cells to bacteria possess their own distinctive delivery processes and mechanisms, which inspires more design and development of cell-based DDSs by integrating the innate functions of cells with the nanoscale characteristics of nanoparticles. In this review article, we focus on the recent advances in cell-based DDSs for site-specific delivery of therapeutics and enhanced treatment of diseases. The promise and perils of cell-based DDSs are also discussed.

The tRNA 3'-end Processing Enzyme tRNase Z2Contributes to Chloroplast Biogenesis in Rice

引用

Journal of Integrative Plant Biology 2013年第11期55卷 1104-1118页

作者： Tuan Long dong Guo dong he Wenjie Shen Xianghua Li National Key Laboratory of Crop Genetic Improvement and National Center of Plant Gene Research (Wuhan) Huazhong Agricultural University

tRNase Z （TRZ） is a ubiquitous endonuclease that removes the 3＇-trailer from precursor tRNAs during maturation. In yeast and animals, TRZ regulates the cell cycle via its （t）RNA processing activity; however, its physiological function in higher plants has not been well characterized. This study describes the identification of a rice （Oryza sativa） TRZ2 mutant; plants homozygous for the osatrz2 mutation were albinos with deficient chlorophyll content. A microscopic analysis of the mutant plants revealed that the transition of proplastids to chloroplasts was arrested at an early stage, and the number and size of the plastids in callus cells was substantially decreased. A genetic complementation test and an RNA interference analysis confirmed that disruption of OsaTRZ2 was responsible for the mutant phenotype. OsaTRZ2 is expressed in all rice tissues, but is preferentially expressed in leaves, sheathes, and calli. OsaTRZ2 was subcellularly localized in chloroplasts, and displayed tRNA 3＇-end processing activity in both in vitro and in vivo assays. In the osatrz2 mutants, transcription of plastid-encoded and nucleus- encoded RNA polymerases was severely reduced and moderately increased, respectively. These results suggest that the tRNA 3＇ processing activity of OsaTRZ2 contributes to chloroplast biogenesis.

Study on the performance of a large-size CsI detector for high energy γ-rays

引用

Nuclear Science and Techniques 2018年第1期29卷 58-64页

作者： he dong De-Qing Fang Chen Li Shanghai Institute of Applied Physics Chinese Academy of Sciences Shanghai 201800 China University of Chinese Academy of Sciences Beijing 100049China

The measurement of high-energy γ-rays is an important experimental method to study the giant resonance in a nucleus, c reaction in nuclear astrophysics, and so on. The performance of a large-size Cs I detector for crays detection is studied by comparison between the experimental measurements and GEANT4 simulation. The reliability of the simulated efficiency for low-energy γ-rays is verified by comparing with the experimental data. The efficiency of the Cs I detector for high-energy γ-rays was obtained by the GEANT4 simulation. The simulation shows that the detection efficiency of 20 Me V γ-rays can reach 3.8%.
