| 1 | Classification and comparison of physical and chemical properties of corn stalk from three regions in China显示文摘Corn stalk samples from Anhui,Jiangxi and Shanghai were used as test materials.Their physical,chemical and thermo-chemical engineering characteristics were analyzed.The similarities and differences in properties of corn stalk from the three regions were determined using SIMCA-P and SPSS software in order to obtain a proper energy utilization method of corn stalk.The results show that the corn stalk from Shanghai has significant differences from the samples of Jiangxi and Anhui.In particular,the following properties of corn stalk from Shanghai such as the contents of cellulose,calcium(Ca),iron(Fe),crude ash,volatile matter,carbon(C),nitrogen(N),and oxygen(O)are significantly different from those of Jiangxi and Anhui samples(P<0.05).While other properties such as the contents of magnesium(Mg),copper(Cu),zinc(Zn),moisture,hydrogen(H),and sulfur(S)have no significant difference among samples of three regions.Compared with the corn stalk in Anhui and Jiangxi,the Shanghai samples are more suitable for the production of ethanol because of their higher ratio of cellulose to hemi-cellulose content.Because of its high content of ash and low calorific value,the Shanghai corn stalk is suitable for the gasification process instead of for direct combustion or bio-oil production.The research can provide a reference for raw material selection for biomass energy production and utilization. | Wang Lu Liu Ronghou Sun Chen Cai Wenfei Tao Yiwei Yin Renzhan Mei Yuanfei | 2014 | International Journal of Agricultural and Biological Engineering2014，7，6： | 5 |

| 4 | Integrated separation-electrochemical detection device based on wood column for online identification of enantiomer显示文摘Chiral chemicals have attracted significant interest in the pharmaceutical industry,yet the separation methods to get pure enantiomers from racemic mixture are still challenging.To date,the separation of enantiomers still mainly depends on chromatography using high-cost chiral stationary phases.Herein,wood channels were used as the handheld integrated device,and enantiomer separation was simultaneously detected using an electrochemical detector.In this method,a chiral UIO-66(L-UIO-66)modified enantiomer separation zone and carbonized wood based online detection zone are integrated along a single wood column.Based on the in situ separation results from the chronoamperometry data,the wood device shows excellent separation ability for a wide range of electrochemically active enantiomers,including 3,4-dihydroxyphenylalanine,amino acids,ascorbic acid,carnitine,and penicillamine with high chirality purity.The unbiased molecular dynamic simulations indicate that the excellent chiral recognition and separation are attributed to the different barriers from the bound states to the dissociated state of the enantiomers in the homochiral microenvironment of the framework.This integrated enantiomer separation-electrochemical detection device provides a novel,easy,and low-cost platform for the separation of pure enantiomer from racemic mixture. | Junli Guo Yuanfei Xue Chenxi Zhao Junjian Zhao Zhida Gao Ye Mei Yan-Yan Song | 2024 | Nano Research2024，17，3： | 0 |
| 5 | Influence of methanol additive on bio-oil stability显示文摘Methanol at different mass concentrations(1,6,11,16,21 wt%)was added into crude bio-oil to upgrade oil properties.Indexes including pH value,water content and viscosity were measured regularly during a storage period of 91 days.GC-MS analysis was conducted before and after storage.An addition of 21 wt%methanol was found to improve the pH value from 2.97 to 3.88,and decrease the water content and viscosity after storage by 35.02%and 81.35%,respectively.The GC-MS analysis result convincingly showed that methanol could inhibit aging reactions such as polymerization and esterification which created new compounds in the oil.The FTIR and NMR analysis showed that methanol caused some structural changes in bio-oil. | Fei Wenting Liu Ronghou Zhou Weiqi Mei Yuanfei Yin Renzhan | 2014 | International Journal of Agricultural and Biological Engineering2014，7，3： | 0 |
