Surface oxygen vacancy defects of mesoporous CeO2 nanosheets assembled microspheres (D-CeO2) are engineered by polymer precipitation,hydrothermal and surface hydrogenation strategies.The resultant D-CeO2 with a main pore diameter of 9.3 nm has a large spe
The selective hydrogenation of C≡C to C=C bonds is an important step,yet remains to be a great chal-lenge in chemical industry.In this study,we have revealed the influence of Pd deposition pH value on the catalytic performance of Pd-CuO/SiO2 catalyst for
Based on the host-guest molecular recognition capability of cucurbit[6]uril (CB[6]) modified on the gold surface,sensitive spectrophotometric and electrochemical methods for the detection of metformin(MET) have been developed.The molecular recognition bet
Herein,the nanoscaled ATP-responsive upconversion metal-organic frameworks (UCMOFs) are aqueous-phase synthesized for co-delivery of therapeutic protein cytochrome c (Cyt c) and chemodrugs doxoru-bicin (DOX),achieving targeted combinational therapy of hum
A new metal-oxo-clusters-based inorganic framework[NaCo2Mo2O7(OH)3]n (NaCoMo),named as 3D platelike ternary-oxo-cluster,has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction structure analysis,FT-IR spectroscopy,powder
新会计准则在计量公允价值上发生较大变化,影响到会计核算工作的开展.基于此,本文首先分析了新会计准则对于会计核算的影响,其次分析了会计核算面临的难题,最后提出了完善会计核算的建议,需要企业多个部门进行协调,充分发挥出会计核算的价值.
Although the selective hydrogenation of α,β-unsaturated aldehyde to unsaturated alcohol (UOL) is an extremely important transformation,it is still a great challenge to achieve high selectivity to UOL due to thermodynamic favoring of the C=C hydrogenation
随着新医改的持续推进,我国公立医院发展环境发生巨大转变,在医改转型发展目标上,需要从既往“数量型、速度型、粗放型”的模式向“质量型、效益型、精细型”的模式转变.在转型目标上,做好全面预算管理是关键,主要通过全面预算管理提高服务质量以及运行效率,而实际上当前管理中却存在各种各样的问题,使得医院持续发展受影响,所以有必要采取合理的干预对策.本文简要阐述公立医院全面预算管理的意义,之后分析预算管理过程存在的问题,并提出合理的对策,以为公立医院的可持续发展奠定有利基础.
Unremitting and intensive researches about efficient non-precious metal electrocatalysts are necessary for large-scale commercial applications of fuel cells,while iron and nitrogen co-doped carbon (Fe-N-C)materials has become one of the most promising ele
Developing highly efficient and cost-effective catalysts for electrochemically oxidizing biomass-derived 5-hydroxymethylfurfural (HMF) into value-added 2,5-furandicarboxylic acid (FDCA) is of great importance.Herein,we report a controllable nitrogen dopin
