| 1 | Brief Introduction of TianHe Exascale Prototype System显示文摘Facing the challenges of the next generation exascale computing,National University of Defense Technology has developed a prototype system to explore opportunities,solutions,and limits toward the next generation Tianhe system.This paper briefly introduces the prototype system,which is deployed at the National Supercomputer Center in Tianjin and has a theoretical peak performance of 3.15 Pflops.A total of 512 compute nodes are found where each node has three proprietary CPUs called Matrix-2000+.The system memory is 98.3 TB,and the storage is 1.4 PB in total. | Ruibo Wang Kai Lu Juan Chen Wenzhe Zhang Jinwen Li Yuan Yuan Pingjing Lu Libo Huang Shengguo Li Xiaokang Fan | 2021 | Tsinghua Science and Technology2021，26，3： | 5 |
| 2 | Large electrocaloric effect in BaTiO_3 based multilayer ceramic capacitors显示文摘The electrocaloric effect(ECE) of multilayer ceramic capacitor(MLCC) of Y5 V type was directly measured via a differential scanning calorimetry(DSC) method and a reference resistor was used to calibrate the heat flow due to the heat dissipation. The results are compared with those calculated from Maxwell relations by using the polarization data obtained from the polarization–electric field hysteresis loops. The direct method shows a larger ECE temperature change, which is accounted for the situation approaches an ideal condition. For the indirect method using Maxwell relations, only the polarization projection along the electric field was taken into account, which will be less than the randomly distributed real polarizations that contribute to the ECE. The MLCCs exhibit a broad peak of ECE around 80 C, which will be favorite for the practical ECE cooling devices. | LU Biao WEN XinHua TANG ZhenHua LIANG Bo TAO Tao XIE ZhiWei ZHANG TianFu TANG XinGui XIANG Yong LIAO Jie LU ShengGuo | 2016 | Science China(Technological Sciences)2016，59，7： | 3 |

| 4 | Alkalinity neutralization and structure upgrade of bauxite residue waste via synergistic pyrolysis with biomass显示文摘Bauxite residues,a large volume solid waste,are in urgent need of effective disposal and management.Especially,strategies to alleviate the high alkalinity of bauxite residue remain a big challenge.Here,we developed a synergistic pyrolysis to neutralize the alkalinity of bauxite residue and upgrade the structure of biomass simultaneously.By cooperating the catalytic feature from bauxite residue,rice straw,a cellulose-enriched biomass,could prefer to produce acidic components under a hypothermal pyrolysis temperature(below 250℃)and partial oxygen-contained atmosphere as evidenced by the synchronous TGA-FTIR analysis.In return,these in-situ produced acidic components neutralized the bauxite residue profoundly(pH decreased from 11.5 to 7.2)to obtain a neutral product with long-term water leaching stability.Also,a higher pyrolysis temperature led to neutral biochar-based products with well-defined carbonization characteristics.Thus,the biomass-driven pyrolysis strategy provides a potential to dispose the alkalinity issue of bauxite residue and further opportunities for the sustainable reuse and continuing management of bauxite residue. | Chuxuan Li Lu Tang Jun Jiang Feng Zhu Jingju Zhou Shengguo Xue | 2020 | Journal of Environmental Sciences2020，32，7： | 1 |
