1Selective oxidation of biomass derived 5-hydroxymethylfurfural to 2,5-diformylfuran using sodium nitrite显示文摘A mild and simple process for the effective oxidation of 5-hydroxymethylfurfural(HMF) into 2,5-diformylfuran(DFF) has been developed using Na NO_2 as the oxidant. Some important reaction parameters were investigated to optimize the oxidation of HMF into DFF. It was found that the reaction solvent was very crucial for this reaction. Trifluoroacetic acid was the best solvent for the oxidation of HMF into DFF by Na NO_2.Under the optimal reaction condition, almost quantitative HMF conversion and high DFF yield of 90.4% were obtained after 1 h at room temperature.Xianxiang Liu Hui Ding Qiong Xu Wenzhou Zhong Dulin Yin Shengpei Su 2016Journal of Energy Chemistry2016,25,1:4

6Preparation and Properties of Bio-Based Flame Retardant L-APP/Poly(L-lactic acid)Composites显示文摘Poly(L-lactic acid)(PLLA)is a thermoplastic material with complete degradability,high biocompatibility and excellent mechanical properties.It can replace petroleum-based polymers are currently being used in the fields of packaging,agriculture,textiles,medical and so on.However,PLLA’s extremely flammability greatly limits its wider application.An bio-based flame retardant L-APP/PLLA composites was prepared by melt blending of the L-APP and PLLA.The morphology,impact properties,thermal properties and flame retardant properties of composites were investigated by field emission scanning electron microscope(SEM),impact tester,differential scanning calorimeter(DSC),thermogravimetric analyzer(TGA),limiting oxygen indexer(LOI)and horizontalvertical burning tester.The results showed that the degree of crystallization(X_(c))and LOI of L-APP/PLLA composites increased as increasing of L-APP content.What’s more,the impact strength first increased and then decreased,the glass transition temperature(T_(g))and melting temperature(T_(m))do not changed significantly.The impact strength of composites was 9.1 kJ/m^(2) at a 5 wt%loading for L-APP,which was the highest level.When the content of L-APP was 20%,the LOI was 30.8%,the Xc was 42.3%and the UL-94 level was V-0.This research can promote the value-added utilization of lignin and the application of PLLA in the fields of flame retardant materials.Qionglin Luo Mingliang Wang Hui Zhang Yuejun Ouyang Hongwei Lin You Shu Shengpei Su 2021Journal of Renewable Materials2021,9,12:1
7Study on the surface-modification of nano-hydroxyapatite with lignin and the corresponding nanocomposite with poly (lactide-co-glycolide)显示文摘To obtain nano-hydroxyapatite/poly(lactideco-glycolide)(n-HA/PLGA)nanocomposite with superior mechanical properties,here,lignin was chosen to surfacemodify for n-HA through co-precipitation method.The different reaction conditions of reaction time,phosphorus source,and the lignin addition amount were studied by fourier transformation infrared spectra,X-ray diffraction,the intuitionistic dispersion experiment,transmission electron microscope and thermal gravimetric analysis.The reaction mechanism and the best appropriate reaction condition were obtained.More importantly,the results of electromechanical universal tester,scanning electron microscope,differential scanning calorimetric analyzer,polarized optical microscopy and dynamic mechanical analysis confirmed that the obtained n-HA could greatly increase the mechanical strength of PLGA,owing to the excellent dispersion and promotion crystallization effect.Moreover,in vitro cell culture experimental results indicated that the n-HA surface-modified by lignin was favorable to improve the cell biocompatibility of PLGA.The study suggested that the introduction of lignin was a novel method to acquire a highly dispersed n-HA,which would provide a new idea to achieve the n-HA/PLGA nanocomposite as bone materials in future,and it would pave the way towards a new application of lignin in biomedical field.Haojie Ding Liuyun Jiang Chunyan Tang Shuo Tang Bingli Ma Na Zhang Yue Wen Yan Zhang Liping Sheng Shengpei Su Xiang Hu 2021Frontiers of Chemical Science and Engineering2021,15,3:1

10Preparation and Properties of Bio-Based Flame Retardant Polyvinyl Alcohol显示文摘Polyvinyl alcohol (PVA) has been widely used in the fields of medical, food and packaging due to its excellentbiocompatibility, good fiber-forming and film-forming properties. However, the high flammability of PVA hasgreatly limited its wider applications. The flame-retardant PVA was prepared by melt blending of a bio-basedflame retardant (prepared from lignin, phosphoric acid and carbamide) with thermoplastic PVA (TPVA). Thechemical structure, morphology, thermal properties, mechanical properties, fire property and fluidity of thisflame retardant PVA were investigated by Fourier transform infrared spectrometer(FTIR), field emission scanning electron microscope(SEM), thermogravimetric analyzer(TGA), impact tester, universal testing machine,horizontal-vertical burning tester, limiting oxygen indexer(LOI) and melt flow rate meter(MFR). The resultsshowed that the prepared flame retardant had good compatibility with the PVA substrate;The impact strength,melt flow rate, fire property and char residue of this PVA material increased with the content of bio-based flameretardant. When the content of flame retardant was of 20%, the five indices including impact strength, meltflow rate, UL-94 level, LOI and char residual were 11.3 KJ/m^(2), 21.2 g/10 min, V-0 UL-94 level, 33.1%, and19.2%, respectively. This research can promote the high-value utilization of lignin and the application ofPVA in the fields of fire protection.You Shu Qionglin Luo Hongwei Lin Yuejun Ouyang Xiaomin Zhang Liping Sheng Shengpei Su 2021Journal of Renewable Materials2021,9,5:1

15Simulation investigations on the marble deterioration by sulphur dioxide显示文摘This paper deals with investigations on corrosion of marble SO2. We have simulated oxidation of SO2 by photochemical process in the atmosphere. The experiments indicate that formation of SO3 aerosols is related to the concentration of SO2, the UV light intensity, the time of irradiation and the humidity of the air. The corrosion feature of surfaces of the marble and the depth profiles of sulphur were obtained by SEM (Scanning electron microscope), EDXA (Energy-dispersive X-ray analyzer) and SIMS (Secondary ion mass spectrometer). The results of experiments show the corrosive extent of marble depends on its compositions and microareas of marble, which contain lower silicon content can be easily corroded by SO2.Gan Weitang, Dai Shugui, Liu Youying, Liu Zhaomeng, Zhang Qingmin,Zhou Xingdi, Su Shengpei, Liu Xiao, Zhu RuiZhi,Fu Xueqi and R.
