1Fabrication of Bi_2O_3/TiO_2nanocomposites and their applications to the degradation of pollutants in air and water under visible-light显示文摘A nanoheterojunction composite photocatalyst Bi2O3/TiO2working under visible-light(λ 420 nm) was prepared by combining two semiconductors Bi2O3 and TiO2 varying the Bi2O3/TiO2molar ratio. Maleic acid was employed as an organic binder to unite Bi2O3 and TiO2 nanoparticles. The SEM, TEM, XRD and diffuse reflectance spectra were utilized to characterize the prepared Bi2O3/TiO2nanoheterojunction. The nanocomposite exhibited unusual high photocatalytic activity in decomposing 2-propanol in gas phase and phenol in aqueous phase and, evolution of CO2 under visible light irradiation while the end members exhibited low photocatalytic activity. The composite was optimized to 5 mol% Bi2O3/TiO2. The remarkable high photocatalytic efficiency originates from the unique relative energy band position of Bi2O3 and TiO2 as well as the absorption of visible light by Bi2O3.Ashok Kumar Chakraborty Md Emran Hossain Md Masudur Rhaman K M A Sobahan 2014Journal of Environmental Sciences2014,26,2:7
2高粱A1型细胞质雄性不育系与保持系线粒体基因组分析比较显示文摘线粒体基因组易位是导致作物细胞质雄性不育(Cytoplasmic male sterility,CMS)性状产生的重要遗传机制。比较高粱A1型细胞质雄性不育系与保持系线粒体基因组,寻找易位区为克隆高粱A1型细胞质雄性不育相关基因奠定基础。以高粱A1型细胞质雄性不育系Tx623A和其保持系Tx623B为试验材料,采用二代Illumina Hiseq结合三代PacBio测序技术,对2个样品的线粒体基因组进行组装,比较和分析不育系和保持系基因组结构和基因差异。高粱Tx623A和Tx623B线粒体基因组大小分别为449 727 bp和452 772 bp,预测编码开放阅读框(Open reading frame,ORFs)分别为147和145个,且两基因组特有基因分别为8个和6个。两线粒体基因组共线性比较分析,发现存在一个57 kb的基因组片段易位的结构变异(Structural variation,SV)区域,该易位区可能与A1型细胞质雄性不育有关。Tx623A和Tx623B线粒体基因组中易位区为高粱A1型细胞质雄性不育基因克隆提供了基因组信息。王平 丛玲 王春语 朱振兴 A Ashok Kumar 张丽霞 陆晓春 2019生物技术通报2019,35,5:3
3阻止威胁视力的新生儿视网膜病变:新生儿学专家的视角显示文摘出生1小时到1周的新生儿护理决定了一个早产儿是否能免于新生儿视网膜病变及其并发症的侵害。氧疗管理及简单易行的干预措施将起到关键作用。我们发现,即便在配备同等水平的设备和医疗人员的条件下,不同的新生儿重症监护病区的ROP的发病率相差很大。Ashok Deorari Brian A Darlow 鲁理(译) 2018实用防盲技术2018,13,2:2
