| 1 | Cold Hydrostatic Sintering:From shaping to 3D printing显示文摘We developed a novel consolidation technique,Cold Hydrostatic Sintering(CHS),which allows near full densification of silica.The technique is inspired by biosilicification and geological formation of siliceous rocks.Unlike established cold sintering method which is based on uniaxial pressure,CHS employs an isostatic pressure to enable room temperature consolidation of bulks having a complex threedimensional shape.The resulting material is transparent(in line transmittance exceeding 70% in the visible range)and amorphous.After drying,the Vickers hardness was as high 1.4 GPa which half of materials consolidated at 1200℃ and it is the highest among all materials processed at room temperature.The CHS method,because of its simplicity,might be suitable for broad range of applications including 3D printing,mould forming and preparation of multi-layered devices.Because of the absence of the firing step,CHS could be directly integrated in the manufacturing of a wide range of hybrid(organic/inorganic)materials for functional and biological applications. | Anna Jiang Daoyao Ke Ludi Xu Qiang Xu Jiang Li Jiabei Wei Chunfeng Hu Salvatore Grasso | 2019 | Journal of Materiomics2019，5，3： | 0 |
| 2 | Content Determination about the Pharmacological Constituents of Salvia miltiorrhiza Cultivated in Jizhou District显示文摘[Objectives] To evaluate the quality of Salvia miltiorrhiza cultivated in Jizhou District. [Methods]With Salvia miltiorrhiza cultivated in Jizhou District as test material,HPLC was used to study the content of its pharmacological constituents( tanshinone II A,tanshinone I and danshinolic acid B). [Results] For Salvia miltiorrhiza cultivated in Jizhou District,tanshinone II A content was 0. 014%,tanshinone I content was 0. 4212%,and danshinolic acid B content was 3. 018%,higher than the standard specified in Pharmacopoeia( 2015).[Conclusions]The quality of Salvia miltiorrhiza met the requirements of medication. | Ludi TIAN Xiujie LIU Yi PEI Zanxue WU Wen XU Fang LIU Jiangli NIE Jinfeng MAO | 2017 | Medicinal Plant2017，8，5： | 0 |
