| 1 | Asymmetric intramolecular oxa-Michael addition of activated α,β-unsaturated ketones by chiral N-triflyl phosphoramide显示文摘Asymmetric intramolecular oxa-Michael addition of activated α,β-unsaturated ketones by chiral N-triflyl phosphoramide was realized. The flavanone products can be synthesized with excellent yields (50%–95%) and up to 74% ee. | FENG Zhen ZENG Mi XU QingLong YOU ShuLi | 2010 | Chinese Science Bulletin2010，55，17： | 2 |
| 2 | Synthesis of Monodisperse CdS Nanorods Catalyzed by Au Nanoparticles显示文摘Semiconductor nanocrystals(dots,rods,wires,etc.)exhibit a wide range of electrical and optical properties that differ from those of the corresponding bulk materials.These properties depend on both nanocrystal size and shape.Compared with nanodots,nanorods have an additional degree of freedom,the length or aspect ratio,and reduced symmetry,which leads to anisotropic properties.In this paper,we report the Au nanoparticle-catalyzed colloidal synthesis of monodisperse CdS nanorods.Based on systematic high resolution transmission electron microscopy studies,we propose a growth mechanism for these nanorods. | Hongwang Zhang Savas Delikanli Yueling Qin Shuli He Mark Swihart Hao Zeng | 2008 | Nano Research2008，1，4： | 2 |

| 4 | Age effect of deafening on stereotyped song maintenance in adult male bengalese finches Lonchura striata domestica显示文摘Birdsong is a complex learned vocal behavior that relies on auditory experience for development.However,it appears that among different species of close-ended songbirds,there are some variations in the necessity of auditory feedback for maintaining stereotyped adult song.In zebra finches,the deterioration of adult songs following deafness depends on the birds' age.It is unknown whether this age effect is a general rule in other avian species as well.Therefore,we chose Bengalese finches,whose songs show more complexity and have much heavier dependency on auditory feedback than that of zebra finches,to compare the degree of song degradation after hearing loss in old(over 18 months old)and young adult birds(5-6 months old).We found that both syllable sequence and syllable phonology were much less severely affected by deafening in old adults than that in young ones.Moreover,young adults almost lost their capability to sing trills over 6 months following deafening,while old birds continued to sing plenty of trills and trilled syllables after the same period of deafening.Our results suggest that age plays an important role in affecting the dependency of adult song maintenance on auditory feedback in Bengalese finches.Furthermore,the age dependency may be a general phenomenon in different species of close-ended songbirds. | Yingyu SUN Rui WANG Shuli SHAO Shaoju ZENG Mingxue ZUO | 2009 | Current Zoology2009，55，3： | 0 |
| 5 | An automatically progressed computer-controlled simulated digestion system to predict digestible and metabolizable energy of unconventional plant protein meals for growing pigs显示文摘The objective of this experimentwas to develop a new computer-controlled simulated digestion system to predict the digestible energy(DE)and metabolizable energy(ME)of unconventional plant protein meals for growing pigs.Nine meals tested included 1 source of rapeseed meal,4 sources of cottonseed meal,2 sources of sunflower meal,and 2 sources of peanut meal.Twenty growing pigs(Duroc[LandraceLarge White])with an initial body weight(BW)of 41.7±2.6 kg were allotted to a replicated 103 incomplete Latin square design to determine the DE and ME of 1 basal diet and 9 experimental diets formulated with 9 unconventional plant protein meals.The DE andMEvalues of unconventional plant protein meals were calculated by the difference method.The in vitro digestible energy(IVDE)of 1 basal diet,9 experimental diets,and 9 unconventional plant protein meals were determined with 5 replicates of each sample in a complete randomized arrangement.The IVDE/DE or IVDE/ME ranged from 0.96 to 0.98 or 1.00 to 1.01,and the correlation coefficient between IVDE and DE or MEwas 0.97 or 0.98 in 10 experimental diets.Accordingly,the IVDE/DE or IVDE/ME ranged from 0.86 to 1.05 or 0.96 to 1.20,and the correlation coefficient between IVDE and DE orME was 0.92 or 0.91 in 9 unconventional plant protein meals.The coefficient of variation(CV)of IVDE was less than that of DE and ME in the experimental diets(0.43%,0.80%,and 0.97%for CV of IVDE,DE and ME,respectively)and unconventional plant protein meals(0.92%,4.84%,and 6.33%for CV of IVDE,DE and ME,respectively).The regression equations to predict DE from IVDE in 10 experimental diets and 9 unconventional plant protein meals were DE=0.8851IVDE t539(R^(2)=0.9411,residual standard deviation[RSD]=23 kcal/kg DM,P<0.01)and DE=0.9880IVDE t 166(R^(2)=0.8428,RSD=182 kcal/kg DM,P<0.01),respectively.Therewas no statistical difference in the slopes(P=0.82)or intercepts(P=1.00)of these 2 equations.Thus,10 diets and 9 unconventional plant protein meals were pooled to establish the regression equation of DE on IVDE as:DE=0.9813IVDE t187(R^(2)=0.9120,RSD=118 kcal/kg DM,P<0.01).The regression equations to predictME from IVDE in 10 experimental diets and 9 unconventional plant protein meals were ME=0.9559IVDE t146(R^(2)=0.9697,RSD=18 kcal/kg DM,P<0.01)and ME=0.9388IVDEt3(R^(2)=0.8282,RSD=182 kcal/kg DM,P<0.01),respectively.Therewas no statistical difference in slopes(P=0.97)but significant difference between the intercepts(P=0.02)of these 2 equations.Our results indicate IVDE has similar response to the DE but different response to the ME in 10 experimental diets and 9 unconventional plant protein meals.Therefore,IVDE is moresuitable to predict DE than ME of diets and unconventional plant protein meals for growing pigs. | Zhongyuan Du Yuming Wang Mingqiang Song Shuli Zeng Lixiang Gao Jiangtao Zhao Feng Zhao | 2022 | Animal Nutrition2022，，3： | 0 |
