| 1 | Higher alcohol synthesis over Cu-Fe composite oxides with high selectivity to C_(2+)OH显示文摘Cu-Fe composite oxides were prepared by co-precipitation method and tested for higher alcohol synthesis from syngas. The selectivity to C2+OH and C6+OH in alcohol distribution was very high while the methane product fraction in hydrocarbon distribution was rather low, demonstrating a promising potential in higher alcohols synthesis from syngas. The distribution of alcohols and hydrocarbons approximately obeyed Anderson-Schulz-Flory distribution with similar chain growth probability, indicating alcohols and hydrocarbons derived from the same intermediates. The effects of Cu/Fe molar ratio, reaction temperature and gas hourly space velocity (GHSV) on catalytic performance were studied in detail. The sample with a Cu/Fe molar ratio of 10/1 exhibited the best catalytic performance. Higher reaction temperature accelerated water-gas-shift reaction and led to lower total alcohols selectivity. GHSV showed great effect on catalytic performance and higher GHSV increased the total alcohol selectivity, indicating there existed visible dehydration reaction of alcohol into hydrocarbon. | Zhenghong Bao Kang Xiao Xingzhen Qi Xinxing Wang Liangshu Zhong Kegong Fang Minggui Lin Yuhan Sun | 2013 | Journal of Energy Chemistry2013，22，1： | 10 |
| 2 | Identification of genes for drought resistance and prediction of gene candidates in soybean seedlings based on linkage and association mapping显示文摘Drought is one of the primary abiotic stress factors affecting the yield,growth,and development of soybeans.In extreme cases,drought can reduce yield by more than 50%.The seedling stage is an important determinant of soybean growth:the number and vigor of seedlings will affect growth and yield at harvest.Therefore,it is important to study the drought resistance of soybean seedlings.In this study,a recombinant inbred line(RIL)population comprising 234 F_(6:10)lines(derived from Zhonghuang35×Jindou 21)and a panel of 259 soybean accessions was subjected to drought conditions to identify the effects on phenotypic traits under these conditions.Using a genetic map constructed by single nucleotide polymorphism(SNPs)markers,18 quantitative trait loci(QTL)on 7 soybean chromosomes were identified in two environments.This included 9 QTL clusters identified in the RIL population.Fifty-three QTL were identified in 19 soybean chromosomes by genome-wide association analysis(GWAS)in the panel of accessions,including 69 significant SNPs(-log_(10)(P)≥3.97).A combination of the two populations revealed that two SNPs(-log_(10)(P)≥3.0)fell within two of the QTL(qPH7-4 and qPH7-6)confidence intervals.We not only re-located several previously reported drought-resistance genes in soybean and other crops but also identified several non-synonymous stress-related mutation site differences between the two parents,involving Glyma.07 g093000,Glyma.07 g093200,Glyma.07 g094100 and Glyma.07 g094200.One previously unreported new gene related to drought stress,Glyma.07 g094200,was found by regional association analysis.The significant SNP CHR7-17619(G/T)was within an exon of the Glyma.07 g094200 gene.In the RIL population,the DSP value of the'T'allele of CHR7-17619 was significantly(P<0.05)larger than the'G'allele in different environments.The results of our study lay the groundwork for cloning and molecular marker-assisted selection of droughtresistance genes in soybeans at the seedling stage. | Yanjun Zhang Zhangxiong Liu Xingrong Wang Yue Li Yongsheng Li Zuowang Gou Xingzhen Zhao Huilong Hong Honglei Ren Xusheng Qi Lijuan Qiu | 2022 | The Crop Journal2022，10，3： | 3 |
| 3 | Porous Hafnium-Containing Acid/Base Bifunctional Catalysts for Efficient Upgrading of Bio-Derived Aldehydes显示文摘Novel organic-inorganic hybrids were synthesized by using HfCl 4 and organic ligand 1H-pyrrole-2,5-dicarboxylic acid(PDCA)via a simple hydrothermal method.The as-prepared Hf-PDCA were characterized by various techniques,such as electron microscope,N_(2) adsorption/desorption,and X-ray photoelectron spectroscopy.Among them,the porous and nitrogen-containing Hf-PDCA as heterogeneous acid/base bifunctional catalyst was then applied to the catalytic hydrogenation of furfural to produce furfuryl alcohol(FFA).It exhibited excellent catalytic performance,with high conversion(98.8%)and selectivity(98.5%)by using 2-propanol as hydrogen source under a relatively mild condition.Moreover,the Hf-PDCA has strong stability and durability,and can be recovered after the catalyst reaction.In addition,the Hf-PDCA as catalyst can be extended to fabricate corresponding alcohols by catalytic conversion of other biomass derived aldehydes. | Fanglin Dai Junrong Luo Shenghui Zhou Xingzhen Qin Detao Liu Haisong Qi | 2021 | Journal of Bioresources and Bioproducts2021，6，3： | 0 |
