问题导入式专题教学模式顺应了新时代教学要求,在强化学生教学中的主体性、增强学生理解的渐入性、激励学生对教学的探索性方面均有其独特的作用。然而在实际的教学过程中思政课专题教学仍然存在认识的片面化、问题导入的单一化、教学内容的拼接化等问题。因此,专题式教学需要做到三点改进:一是引导与培训并重,加快教师教学认知迁移;二是人本与建构并行,强化专题教学问题引领;三是教学与科研并联,整合学科教材知识内容。

2016年全国植物生物学大会

Diacylglycerol kinase(DGK) is a kind of phosphokinase involved in the formation of signaling molecule phosphatidic acid(PA) in plants. In this study,seven maize(zea mays) DGK gene family members were identified by bioinformatics analysis,and designated as ZmDGK1-7. The proteins encoded by ZmDGKs had a molecular weight(MWs) between 54.6 and 80.2 k Da,and predicted PI values of 6.08 to 8.74,respectively. Phylogenetic analysis revealed that ZmDGKs fall into three clusters. While all ZmDGKs have a conserved catalytic domain DGKc,only ZmDGK1,ZmDGK4 and ZmDGK5 have the DAG/PE binding domain. Gene expression of ZmDGKs were detected in roots,stem,leaves,and endosperm tissues. ZmDGKs genes were also significantly up-or down-regulated in response to drought,salt and low temperature treatment. We identified maize DGK genes,and conducted bioinformatics and gene expression analysis under several abiotic stresses,which will help us to decipher the functions of maize diacylglycerol kinase family and their roles in maize growth,development and responses to environmental changes.

Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.
