| 1 | Study on the Effect of Two-Step Saturated Steam Heat Treatment Process on the Properties of Reconstituted Bamboo显示文摘With the aim of utilizing reconstituted bamboo as a carbon cycle oriented material,the improvement of physical and mechanical properties has been actively studied to solve using problems The saturated steam heat treatment process has been widely used in worldwide.With the development and exploration of this technology,two step satu-rated steam heat treatment process appears in some practical production,that is,affer a period of saturated steam heat treatment at a lower temperature,the bamboo bundles are taken out and seasoned for a period of time,and then put back into the heat tank again,and heated at a higher temperature for another period of time.During the two-step saturated steam heat treatment,the physical and mechanical properties of bamboo changed.However,the mechanism of two step saturated steam heat treatment has not been thoroughly discussed.For purpose that this paper all discuss and find out the mechanism of two step saturated steam heat treatment on the change of physical and mechanical properties of reconstituted bamboo.In this work,the one and two step saturated steam heat treat-ments were carried out according to the actual production parameters,and the physical and mechanical properties of the reconstituted bamboo board made of treated bamboo bundles were analyzed,including the color change,the thickness swelling(TS),modulus of elasticity(MOE),modulus of rupture(MOR)and shear strength.The results indicate that two-step saturated steam heat treatment is better than one step.Based on the detailed study of the chemical composition,crytalinity and micro morphologial characteristics of the heated bamboo bundles,it is further revealed that during two-step saturated steam heat treatment,oxygen air is added to the reaction system between the two heat treatment processes to further catalyze the oxidation of hemicellulose and enhance the crystal-linity of cellulose,so as to improve the properties of the final products.Our work has optimized the saturated steam heat treatment process which is widely used in industry,pointing out a new idea in the experimental and theoretical basis for the development of recombinant bamboo manufacturing industry. | Xin Han Zhichao Lou Chenglong Yuan Xinwu Wu Jie Liu Fujin Weng Yanjun Li | 2022 | Journal of Renewable Materials2022，10，12： | 1 |

| 4 | An adjustable multi-color detector based on regulating TiO_(2)surface adsorption and multi-junction synergy显示文摘A TiO_(2)-based multi-color photodetector with controlled photoelectric response to ultraviolet(UV)and visible light is developed by using band regulation technologies such as multi-junction synergy and surface adsorption.This photodetector is manufactured via a continuous process including magnetron sputtering,hydrothermal growth,hydrogen annealing,spin coating and thermal evaporation assembly to form a structure of N-doped TiO_(2)/hydrogenated-TiO_(2)/p-Si heterojunction.These synergistic effects form electronic potential wells in the device to control the electrical transport and spectral response of photo-generated carriers.In the air,the device exhibits a controllable photodetection ability that responds to visible light at positive voltages and UV light at negative voltages.But in vacuum(<0.1 Pa),the photodetection ability of the device at negative voltages is greatly reduced due to the lack of barrier effect caused by surface adsorption.On the contrary,the photodetection ability at positive voltage(e.g.,4 V)has been greatly improved,and the quantum efficiency reaches 206.6%under the 480 nm wavelength light.The device has a controllable ability to detect UV and visible light depending on the environments,which is very useful in the fields of environmental detection,chemical sensing and multi-color communication,etc. | Tao Ji Shuqing He Fujin Ai Jianghong Wu Li Yan Junqing Hu Meiyong Liao | 2021 | Nano Research2021，14，10： | 1 |
| 5 | Diagnosis and Control of Rabbit Hemorrhagic Disease(RHD)显示文摘In this study,chronic-type rabbit hemorrhagic disease occurred in rabbit warrens of Shandong,Liaoning,Beijing and Hebei,which was mainly characterized by deaths of young and adult rabbits,longer durationand nerve symptoms,was surveyed by epidemiological investigation,bacterial isolation and incubation,artificial infection test and histopathological method to analyze the causes of chronic-type rabbit hemorrhagic disease and put forward the corresponding control measures. | Fang XIANG Rui GUO Hongxue ZHANG Fujin LI Changhao LIU Qiumei SHI Xinhua SHAO | 2016 | Agricultural Biotechnology2016，5，1： | 0 |
| 6 | Short communication Solvothermal synthesis of trigonal selenium with butterfly-like microstructure显示文摘We present a facile synthesis of trigonal selenium with butterfly-like microstructure from elemental selenium via a solvothermal and aging route.By using X-ray diffraction and scanning electron microscopy to characterize the products,a possible growth mechanism is proposed.The solvothermal process promotes the dissolution of selenium in ethylenediamine to form a brown homogeneous[Se(en)_x]solution.By introducing acetone into this[Se(en)_x]solution,amorphous selenium nanoparticles were produced which then transformed into trigonal selenium,which further assembled along the c-axis to form hexagonal rods.Owing to stereo hindrance as well as to development of opposite lateral sides of the hexagonal rod in opposing directions,a butterfly-like microstructure consisting of two long outside rods and a short inner rod was obtained. | Kai Zeng Shuguang Chen Yande Song Haibin Li Fujin Li Peng Liu | 2013 | Particuology2013，11，5： | 0 |
| 7 | Histopathological Observation of Parvovirus Infection in Foxes显示文摘In this study,histopathological changes in the heart,liver,spleen,lung,kidney,intestine,brain and other organs of foxes died of parvovirus infection were observed. According to the results,multiple organs of infected foxes were congested and hemorrhaged with tissue damage,inflammatory cell infiltration and a series of pathological changes,mainly exhibiting hepatic cell cord rupture,liver cell granular degeneration and fatty degeneration,small intestinal mucous membrane shedding,intestinal villi necrosis and shedding,severe hemorrhage of lamina propria with inflammatory cell infiltration,and severe small intestinal bleeding.This study laid a solid foundation for clinical diagnosis,prevention and treatment of parvovirus infection in foxes. | Fang XIANG Juan CHEN Minghe YU Guohui WANG Qiumei SHI Yanying ZHANG Yongmei SU Guangping GAO Guisheng GAO Fujin LI Lijuan ZHAO | 2015 | Agricultural Biotechnology2015，4，6： | 0 |
