针对沿海牡蛎养殖模式的特点,使用WorldView-2.像为数据源,以浙江省象山港牡蛎养殖区为研究区,采用主成分分析(Principal Component Analysis,PCA)、GS(Gram-Schmidt)变换、NNDiffuse Pan Sharpening、Brovey变换、小波变换(Wavelet Transform)5种融合方法对多光谱和全色影像数据进行融合,选用均值、标准差、信息熵、平均梯度、相关系数和光谱扭曲程度6种客观评价指标,对5种融合结果进行主观定性和客观定量的评价与分析。结果表明:整体上,经PCA方法融合后的遥感影像在保持空间纹理细节信息的同时,光谱信息保持较好,是WorldView-2.像进行沿海牡蛎养殖遥感应用时最适合的融合方法;GS融合效果仅次于PCA;而NNDiffuse Pan Sharpening、Wavelet变换和Brovey变换均不适合浮筏识别与提取。

Crystal-phase-controlled PtSn intermetallic nanowires for efficient methanol oxidation

引用

Science china Chemistry 2024年

LTD Shenzhen Research Institute of Hunan university

Developing highly efficient Pt-based methanol oxidation reaction（MOR） catalysts is pivotal for direct methanol fuel cells. Phase engineering of nanomaterials offers a promising strategy to improve their catalytic performance, yet achieving phase modulation in one-dimensional nanowires（NWs） remains a great challenge. Herein, we report a facile and one-pot synthesis approach for the crystal-phase-controlled Pt-Sn intermetallic nanowires（NWs）, realizing the crystal-phases regulation of face-centered cubic Pt3.n intermetallic NWs（FCC-Pt3.n INTNWs） and hexagonal close-packed PtSn intermetallic NWs（HCP-PtSn INTNWs） by adjusting the amounts of Sn precursors. Notably, the FCC-Pt3.n INTNWs exhibit high mass and specific activities of6.4 A mg-1Pt and 11.8 m A cm–2. respectively, surpassing its counterparts, the HCP-PtSn INTNWs and commercial Pt/C *** a 10,000 s durability test, the FCC-Pt3.n INTNWs still maintain a mass activity of 5.6 A mg-1Pt, which is 2..3.times higher than that of commercial Pt/C catalyst. This dramatic enhancement of MOR performance is primarily attributed to the phasecontrolled structure and accelerated removal of CO intermediates（CO*）. Theoretical calculations and CO stripping experiments demonstrate that the FCC-Pt3.n INTNWs lower the energy barrier for converting CO* into COOH* by reducing CO* binding and enhancing OH adsorption, thus significantly improving the MOR activity, CO tolerance, and stability.

Construction of a host range-expanded hybrid baculovirus of BmNPV and AcNPV, and knockout of cysteinase gene for more efficient expression

引用

Science china(Life Sciences) 2004年第5期47卷 406-415页

作者： WU Xiaofeng, cao Cuiping, XU Yaxiang & LU Xingmeng College of Animal Sciences, zhejiang university, Huajiachi Campus, Hangzhou 3.002.,{2. 1. College of Animal Sciences Zhejiang University Huajiachi Campus 310029 Hangzhou China

AcNPV (Autographa californica nuclear polyhedrosis virus) and BmNPV(Bombyx mori nuclear polyhedrosis virus) are two principal insect-baculovirus expression systems, each having different characteristics. AcNPV has a wider host range and can infect a series of cell lines thus making it suitable for cell suspension culture expression, but the small size of the host insect, A. californica, makes AcNPV less suitable for large scale protein synthesis. In contrast, BmNPV can only infect the silkworm, Bombyx mori, which is well-known for its easy rearing and large size. These characteristics make the BmNPV system especially suitable for large-scale industrial ex-pression. To utilize the advantages of both AcNPV and BmNPV, we tried to expand their host range through homologous recombination and successfully constructed a hybrid baculovirus of AcNPV and BmNPV, designated as HyNPV. The hybrid baculovirus can infect the hosts of both AcNPV and BmNPV. Taking the human basic fibroblast growth factor (bFGF) gene as an appli-cation example, we constructed a recombinant, HyNPV-bFGF. This construct is able to express the bFGF protein both in silkworm larvae and in common-use cell lines, sf2., sf9 and High-five. Moreover, to reduce the loss of recombinant protein due to degradation by proteases that are simultaneously expressed by the baculovirus, we knocked out the cysteinase gene coding for one of the most important baculovirus proteases. This knockout mutation improves the produc-tion efficiency of the bFGF recombinant protein.
