1Relation between seed size in different plant species and response of their seedlings to double CO_2显示文摘ATMOSPHERIC CO2 concentration is predicted to increase to 700μL/L by the middle of the 21st century. The impacts of raising CO2 on vegetation and ecosystem have been intensively studied. It is well known that C3 species and C4 species responded much differently to double CO2. Potential enhancement of photosynthesis efficiency induced by double CO2 in C3 plants was almost 66%, but in C4 plants only 4%. The response to double CO2 in C3 species mightDING Li, ZHANG Chonghao, BAI Kezhi and KUANG Tingyun1 Department of Biology, Beijing Normal University, Beijing 100875, China 2.

3Effects of extrusion conditions on the physicochemical properties of soy protein/gluten composite显示文摘Soybean protein-gluten blend was extruded using a co-rotating twin-screw extruder.Effects of different extrusion conditions on the textural properties of extrudates were analyzed by central composite design through the evaluation of texturization index,water holding capacity,and hardness of extruded protein products.Extrusion process variables including feed moisture content(40%-60%),screw speed(12-20 Hz),extrusion temperature(120℃-180℃),and gluten content(16%-32%)were studied by the nonlinear regression equations analysis.The extrusion process was also optimized using response surface methodology(RSM).The influence of moisture content on the hardness of extrudate was the most significant.The optimized results,including feed moisture content,extrusion temperature,screw speed and gluten content were 49.18%-50.15%,155.24℃-159.86℃,16.41-16.73 Hz,20.00%-20.03%,respectively.The microstructures of TISP products were analyzed by scanning electron microscopy(SEM)and the changes of protein molecules before and after extrusion were also analyzed by SDS-PAGE electrophoresis.Min Wu Yang Sun Chonghao Bi Fang Ji Borui Li Junjie Xing 2018International Journal of Agricultural and Biological Engineering2018,11,4:1
4Rheological properties and fractal-rheology analysis of peanut protein isolate suspension显示文摘This study focuses on the non-linear rheological property and microstructure of peanut protein isolate(PPI)aggregation suspension.The impact of higher harmonics(I3 and I5)on fundamental stress wave during large amplitude oscillatory shear test was studied.Rheological test show that storage modulus G′and loss modulus G″increased with increasing PPI concentration.The non-linear viscoelastic properties of PPI suspension with different concentration were investigated.Using confocal laser-scanning microscopy method,this research explored the microstructure of PPI suspension as well as the fractal dimensions.The new critical strain indirect method combined with Wu-Morbidelli model to calculate the fractal dimension(2.9225)is very close to the actual fractal dimension(2.9206).Fourier Transform Rheology was adopted to get the new critical strain for fractal dimension calculation,which was proved to be feasible.Chonghao Bi Shangyi Chi Zhe Hua Dong Li Zhigang Huang Yi Liu 2020International Journal of Agricultural and Biological Engineering2020,13,6:1
5High-fidelity transfer of area-selective atomic layer deposition grown HfO_(2)through DNA origami-assisted nanolithography显示文摘DNA origami-assisted nanolithography(DOANL)for fabricating custom-designed nanomaterials through pattern transfer from DNA origami to different substrates materials are presented.However,the pattern's integrity and resolution face considerable challenges due to the uncontrollable growth of the nanomaterials during transformation and the unclear mechanism of DOANL.Herein,we report a DOANL combined with area-selective atomic layer deposition(ALD)strategy for fabricating custom shapes hafnium oxide(HfO2)with the high-fidelity and high-throughput.We find that the HfO_(2)selectively grows on DNA origami substrates in a hydroxyl-rich area instead of a methyl-rich protective layer.Combined with the merit of the area-selective ALD method,theHfO_(2)atom selectively coated on the DNA origami surface,thus,precisely modeling the shapes with high-precision in our study based on the surface groups difference of DNA origami and the naked hexamethyldisilane(HMDS)-treated substrates,which reveal the mechanical of high-fidelity pattern transfer based on DOANL.As a result,DNA origami structures can program the shape ofHfO_(2)nanostructures.The DOANL that is based on the principle of'bottom-up'precision assembly breaks through the shape complexity and high-throughput fabrication limitation of theHfO_(2)nanostructures,including two-and three-dimensional structures,plane and curved structures,monolithic and hollow structures.Based on the'top-down'accurate fabrication principle,the area-selective ALD on methyl-rich protective layer substrates improves the integrity and resolution of the pattern transfer process.Overall,this work provides a general technology for nanofabrication strategy.Xiaowan Yuan Daiqin Xiao Wei Yao Zhihao Zhang Lin Yang Liyuan Zhang Yibo Zeng Jiaqi Liao Shanxiong Luo Chonghao Li Hong Chen Xiangmeng Qu 2022Nano Research2022,15,6:0
6Protein aggregation in association with delayed neuronal death in rat model of brain ischemia显示文摘To investigate the relationship between protein aggregation and delayed neuronal death,we adopted rat models of 20 min ischemia.Brain ischemia was produced using the 2-vessel occlusion(2VO)model in rats Light microscopy,transmission electronic microscopy and Western blot analysis were performed for morphological analysis of neurons,and protein detection.The results showed delayed neuronal death took place at 72 h after ischemia-reperfusion,protein aggregates formed at 4 h after reperfusion and reached the peak at 24 h after reper-fusion,and Western blot analysis was consistent with transmission electronic microscopy.We conclude that protein aggregation is one of the important factors leading to delayed neuronal death.Pengfei GE Tianfei LUO Shuanglin FU Wenchen LI Chonghao WANG Chuibing ZHOU Yinan LUO 2008Frontiers of Medicine2008,2,1:0
7Effects of salt ions on rheological properties of SPI-GG hybrid system显示文摘The rheological characteristic of soy protein isolate(SPI),is one of the most important properties in its application in food industry.The effects of different concentrations of guar gum(GG,polysaccharide)and sodium chloride(salt ion)on the rheological properties of SPI were studied in this research.Steady-state shear,strain sweep and frequency sweep tests(static and dynamic rheological tests)were performed,and the following phenomenon and conclusions were drawn:(1)The viscosity of the hybrid system increases with the GG addition.This trend could also be seen with the appropriate adding of salt ion;(2)As the applied frequency increases,the storage modulus G′and the loss modulus G″of the hybrid system increase at a similar rate.And the frequency sweep parameters of the hybrid system rise significantly with the increase of both GG and ionic concentration;The frequency dependence of the system varies significantly with the addition of salt ion;(3)With the concentration of the salt ion increase,the storage module G′of the hybrid system decrease indicating that salt ion destroyed the network structure of hybrid dispersion to a certain extent.Bi Chonghao Zhang Yulai Wu Min Ni Zijian Li Gang Liu Yi Li Dong Liu Yude Huang Zhigang 2017International Journal of Agricultural and Biological Engineering2017,10,5:0
8Effects of xanthan gum on the rheological properties of soy protein dispersion显示文摘This study focused on the effects of addition of xanthan gum(XG)on the rheological properties of soy protein isolate(SPI)solution.Three types of tests(steady shear test,strain sweep test,and frequency sweep test)were performed to figure out the influences of shear rate on the viscosity of the SPI-XG hybrid system,the effects of strain variable on the storage modulus of the hybrid system,and the effects of frequency on both the storage modulus and the loss modulus of the hybrid system,respectively.SPI-XG hybrid system showed more obvious shear-thinning properties compared to pure SPI and pure XG solution.Meanwhile,it was found that the critical point of hybrid system was highly related to the XG concentration.XG can postpone the critical point strain amplitude to a higher value,and the addition of XG can enhance the strain resistance of hybrid system.The concentration of XG influenced the viscoelastic frequency dependence of the hybrid system significantly and complicatedly.After the addition of XG,the correlation between G′and frequency changed from negative to positive.Chonghao Bi Fei Gao Yingdan Zhu Fang Ji Yulai Zhang Dong Li Zhigang Huang 2018International Journal of Agricultural and Biological Engineering2018,11,2:0
