| 1 | Preparation and Properties of Nanocellulose/Sodium Alginate Composite Hydrogel显示文摘Cellulose nanofiber(CNF)was isolated from Okara using deep eutectic solvent(DES)with high-speed stirring.The composite hydrogels obtained by using different proportions of CNF and sodium alginate(SA)had different properties.The CNF/SA composite hydrogels were analyzed using Fourier transform infrared spectroscopy and scanning electron microscopy and tested for compression properties,rheological properties,water content,and swelling degree.Physical crosslinking between SA and Ca^(2+),and different degrees of hydrogen bond formation between SA and CNF were observed.The CNF/SA composite hydrogel have great potential as reinforcements in eco-friendly composite hydrogels for diverse applications. | Peiyi Li Ruiyan Liu Haozhe Lei Miaomiao Zhou Boxing Jian Xinping Li | 2021 | Paper And Biomaterials2021，6，4： | 4 |
| 2 | Effect of High Pressure Homogenization Treatment on Structure and Properties of Soybean Residue Cellulose Nanofibers显示文摘To reduce the adverse effects of non-cellulose materials on subsequent homogenization,the effects of a high-pressure homogenization treatment on the structure and properties of cellulose nanofibers(CNF)prepared by acid treatment of soybean residue were studied.The effects of the number of homogenization step on the microfibrillation degree,crystalline structure and mechanical properties of the soybean residue were analyzed by SEM,FT-IR,XRD,TG and DTG.The results showed that an increase in the number of homogenization steps led to an increase in the degree of microfibrillation,a more uniform distribution of the CNF diameter,and an increase in the crystallinity of CNF.However,but when the number of homogenization steps exceeded 15,the rate of change decreased,and the crystallinity of CNF decreased.As the number of homogenization steps increased,the average degree of polymerization and average molecular weight of CNF decreased continuously,and after 15 homogenization steps,their rate of change also decreased.Therefore,15 steps of high-pressure homogenization represented a suitable number of steps to prepare the soybean residue CNF with an average diameter of 15 nm. | Peiyi Li Yumeng Wang Binyao Zhou Qingqing Hou Hezhen Liu Haozhe Lei Boxing Jian Xinping Li | 2019 | Paper And Biomaterials2019，4，4： | 4 |
| 3 | Anti-aggregation dispersion of ultrafine particles by electrostatic technique显示文摘The dispersion of ultrafine particles in the air can be achieved by mechanical method or surface modification. In this work, the electrostatic technique was first employed for anti-aggregation of ultrafine particles. When the relative humidity of the air is within the region of 70%-75%, effective storage time of ultrafine particles can reach 72 h after treatment by the electrostatic technique. The experimental results showed that this technique imparted ultrafine particles much more pronounced anti-aggregation property. In the dry air, the critical diameter of ultrafine particles anti-aggregated by the electrostatic technique is the function of particle property and charging field intensity. The critical diameter is inversely proportional to the square of the charging field intensity. | REN Jun LU Shouci SHEN Jian YU Chunhong HU Boxing | 2001 | Chinese Science Bulletin2001，46，9： | 3 |
| 4 | Dispersion characteristics of fine particles in water,ethanol and kerosene显示文摘Dispersion behavior of hydrophilic calcium carbonate particles and hydrophobic talcum particles in water, ethanol and kerosene media has been studied by sedimentation analysis. It is found that the dispersion of fine particles complies with the principle of polarity compatibility. That is to say, the dispersion effect will be improved when surface polarity of particles is similar to that of liquid media. The adsorption models of oleic acid on the surface of particles in water and ethanol are proposed. | REN Jun LU Shouci SHEN Jian HU Boxing | 2000 | Chinese Science Bulletin2000，45，15： | 2 |

| 6 | Novel thermogelling poly(ε-caprolactone-co-lactide)-poly(ethylene glycol)-poly(ε-caprolactone-co-lactide) aqueous solutions显示文摘The aqueous solutions of poly(e-caprolactone-co-lactide)-poly(ethylene glycol)poly(e-caprolactone-co-lactide) undergoing sol-gel transition as the temperature increases from 20 to 50℃were successfully prepared. The thermogelling triblock copolymers were synthesized by subtle tuning of the chemical composition and the hydrophilicity/hydrophobicity balance. The sol-gel transition was studied focusing on structure-property relationship. The amphiphilic copolymer formed micelles in aqueous solutions. It is believed to have potential applications in drug delivery and tissue engineering. | Zhi Qiang Jiang, Xian Mo Deng, Jian Yuan Hao Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, P.O.

| 7 | A Novel Zirconium-Based Perovskite-Type Membrane Material for Oxygen Permeation显示文摘A novel zirconium-based membrane material of BaCo0.4Fe0.4Zr0.2O3-δ with cubic perovskite structure was synthesized for the first time through a method of citric and EDTA acid combined complexes. The structural stability was characterized by XRD, O2-TPD and H2-TPR techniques respectively. The high oxygen permeation flux of 0.873 mL/cm2·min at 950(C was obtained under He/Air gradient. Meanwhile, the single activation energy for oxygen permeation and the long-term steady operation of 200 h at 800℃ were achieved. | Jian Hua TONG, Wei Shen YANG*, Rui CAI, Bai Chun ZHU State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics Chinese Academy of Sciences, P.

| 8 | Okara Cellulose Nanofibrils Produced by Pretreatment with Sustainable Deep Eutectic Solvent Coupled with Various Mechanical Treatments显示文摘In this study,a green,environmentally friendly method for rapid cellulose nanofribril(CNF)preparation with a significant cost advantage was developed.Pretreatment with a deep eutectic solvent(DES)synthesized from oxalic acid dihydrate and choline chloride(ChCl-O)was combined with various mechanical treatment methods to produce okara CNFs from agricultural waste,with different diameter distributions.The results showed that high-speed stirring produced CNFs with an average diameter of 27 nm.This method was advantageous because it consumed about 94%less energy than traditional high-pressure homogenization method.The DES recovery rate was more than 90%,and DES served as a highly effective treatment,indicating that DES pretreatment is an economical,convenient,and effective strategy for okara CNF preparation. | Peiyi Li Haozhe Lei Boxing Jian Ruiyan Liu Miaomiao Zhou Yumeng Wang Hezhen Liu Yun Wang Bingyao Zhou | 2022 | Paper And Biomaterials2022，7，2： | 0 |
| 9 | A CASE OF REFERENCE ON COMPLEXITY显示文摘The author argues that the population system of human societies, the highest form of lives on the planet, may serve as standard paradigm for study of complex systems.it turned out to be a well investigable, nonlinearly controllable dyn^mlc system, where census plays pivotal role. The theory has led China to succeed in checking the upsurge of population growth of 1970-80s and remains reliable basis for family-plannlng policy-making in all countries world-wide. It suggests that statistics could be a powerful tool in studying holistic properties of complex systems. | SONG Jian (Chinese Academy of Engineering, Box 3847, Beijing 100038, China) | 2003 | Journal of Systems Science & Complexity2003，16，3： | 0 |
