| 1 | Preparation and characterization of Al/B/Fe_2O_3 nanothermites显示文摘A sol-gel synthetic approach combined with an ultrasonic method was utilized to prepare Al/B/Fe2O3 nanothermites.The structure and properties of the prepared nanothermites were characterized by thermogravimetric analysis,differential scanning calorimetry,scanning electron microscopy,X-ray diffraction,and an impact sensitivity test.The results verified that the nano-aluminum and the micro-boron were uniformly dispersed in the pores of the iron oxide gel.The heat of the prepared Al/B/Fe2O3 nanothermites was 1.3 times that of the simple physically mixed sample.In addition,the heat of the combustion test showed that these materials were indeed energetic.Small-scale safe experiments also showed that the prepared materials through sol-gel were relatively insensitive to standard impact. | SHEN LianHua LI GuoPing LUO YunJun GAO Kun GE Zhen | 2014 | Science China Chemistry2014，57，6： | 6 |
| 2 | Fabrication and thermal decomposition of glycidyl azide polymer modified nitrocellulose double base propellants显示文摘Glycidyl azide polymer(GAP) with the advantages of non-volatility and excellent thermal stability is a candidate as a replacement for nitroglycerine(NG) in a double base propellant. The GAP-NC double base propellants were formulated with GAP and nitrocellulose(NC) fibers. Tensile test and SEM characterization indicated that GAP-NC propellants had a homogeneous structure. Thermogravimetric analysis of GAP-NC propellants revealed that the onset decomposition temperature reached a high level ranging from 192.9 to 194.6 °C, which indicated that the substitution of NG with GAP contributed to the safe storage and process operations for double base propellant. The result analysis of decomposition products of GAP-NC propellants showed that the main gas decomposition products of the propellants were NO, NO_2, CO, CO_2, NH_3, CH_4, HCN, N_2, CH_2O and C_2H_4O. The thermal decomposition process of the specimens was proposed. | Benbo Zhao Tianfu Zhang Zhen Ge Yunjun Luo | 2016 | Science China Chemistry2016，59，4： | 2 |
| 3 | Cryo-EM structure of activated bile acids receptor TGR5 in complex with stimulatory G protein显示文摘Dear Editor,Takeda G protein-coupled receptor 5(TGR5),also known as G protein-coupled bile acids(BAs)receptor 1(GPBAR1),1 belongs to the class A GPCR subfamily.The major TGR5-dependent actions of BAs include maintaining energy homeostasis,regulating glucose/lipids metabolism,as well as immunosuppressive properties.2 TGR5 is identified as a potential therapeutic target for protecting hepatocytes from bile acid overload,preventing atherosclerosis,and inhibiting macrophage inflammation due to its critical role in bile acid sensitization.Thus,elucidation of structural characteristics of TGR5 and its activation mechanism would benefit the discovery of therapeutic drugs for these metabolic disorders. | Geng Chen Xiankun Wang Yunjun Ge Ling Ma Qiang Chen Huihui Liu Yang Du Richard DYe Hongli Hu Ruobing Ren | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
