| 1 | MoSi_2 oxidation resistance coatings for Mo_5Si_3/MoSi_2 composites显示文摘In order to improve the oxidation resistance properties of 30 at.% Mo5Si3/MoSi2 composite at high temperature in air, a molybdenum disilicide coating was prepared on its surface by a molten salt technology. XRD and SEM analysis showed that only tetragonal MoSi2 phase existed in the coating after being siliconized for 5 h at 900°C. The oxidation film formed on the uncoated sample was not dense, so that oxygen diffused easily through it. The volatilization of MoO3 resulted in the oxidation film separating from the substrate. The MoSi2 coating was proved to be an effective method to prevent 30 at.% Mo5Si3/MoSi2 composites from being oxidized at 1200°C. A dense glassy SiO2 film was formed on the MoSi2 coating surface, which acted as a barrier layer for the diffusion of oxygen atoms to the substrate. The 30at.% Mo5Si3/MoSi2 composites with a MoSi2 coating showed much better oxidation resistance at high temperature. | YAN Jianhui XU Hongmei ZHANG Houan TANG Siwen | 2009 | Rare Metals2009，28，4： | 8 |

| 3 | SHRIMP dating of volcanic rock in the Zhangwu-Heishan area, West Liaoning province, China: Its relationship with coal-bearing strata显示文摘The Zhangwu-Heishan area is located to the east of the Fuxin-Yixian Basin and is mostly covered with volcanic rock. At various periods, different geologists had varying opinions about their age and periods of volcanic eruptions, especially on sequences between volcanic rock and main coal-bearing strata, which affect the direction of searching for coal, as well as prospecting the entire research area. During our study, we carried out detailed field investigations in this research area; observed and recorded the main repre- sentative outcrops of volcanic rock. We collected over 20 volcanic rock samples and tested the Sensitive High Resolution Ion Microprobe II (SHRIMP II) U-Pb isotope age of 11 samples. The age of our volcanic rock samples ranged between 56.0 ± 2.9 and 132.3 ± 2.3 Ma. After taking earlier investigations into con- sideration, we concluded that, except for a suite of paleogene olivine basalt, the volcanic rock in the Zhangwu-Heishan area is younger than the coal-bearing Shahai Formation. It is therefore most unlikely to find coal seams equivalent to those of the early Cretaceous Shahai Formation in Fuxin Basin below vol- canic rock. | Cai Houan XU Debin Li Baofang Shao Longyi | 2011 | Mining Science and Technology2011，21，5： | 2 |

| 9 | In-situ constructing Cu_(1)Bi_(1)bimetallic catalyst to promote the electroreduction of CO_(2)to formate by synergistic electronic and geometric effects显示文摘Electrochemical CO_(2)reduction to formate is a potential approach to achieving global carbon neutrality.Here,Cu1Bi1bimetallic catalyst was prepared by a co-precipitation method.It has a ginger like composite structure(CuO/CuBi_(2)O_(4))and exhibited a high formate faradaic efficiency of 98.07%at–0.98 V and a large current density of–56.12 mA.cm^(-2)at–1.28 V,which is twice as high as Bi2O3catalyst.Especially,high selectivity(FE^(–)_(HCOO)>85%)is maintained over a wide potential window of 500 mV.In-situ Raman measurements and structure characterization revealed that the reduced Cu1Bi1bimetallic catalyst possesses abundant Cu-Bi interfaces and residual Bi-O structures.The abundant Cu-Bi interface structures on the catalyst surface can provide abundant active sites for CO_(2)RR,while the Bi-O structures may stabilize the CO_(2)^(*–)intermediate.The synergistic effect of abundant Cu-Bi interfaces and Bi-O species promotes the efficient synthesis of formate by following the OCHO^(*)pathway. | Houan Ren Xiaoyu Wang Xiaomei Zhou Teng Wang Yuping Liu Cai Wang Qingxin Guan Wei Li | 2023 | Journal of Energy Chemistry2023，，4： | 1 |

| 11 | High Temperature Oxidation Behavior of La_2O_3-Mo_5Si_3/MoSi_2 Composites显示文摘The oxidation behavior of 0.8%La2O3-Mo5Si3/MoSi2 composites at 1200 ℃ in air was investigated. The results reveal that the oxidation resistance of the material with 0.8% La2O3 and Mo5Si3 is impaired. The oxidation resistance is decreased with increasing Mo5Si3 content. The mass loss follows a linear law in the initial oxidation. With oxidation time prolonging, a continuous and dense oxidation scale prevents oxygen from diffusing and leads to mass change a little increasing when the Mo5Si3 content is less than 30%. However, the composite shows “PEST” with the addition of 40% Mo5Si3. With increasing Mo5Si3 content, the oxidation resistance of 0.8%La2O3-Mo5Si3/MoSi2 decreases. This attributes to the poor oxidation resistance of Mo5Si3 and the relative density decreasing of 0.8% La2O3-Mo5Si3/MoSi2 composite. In addition, the addition of rare earths and Mo5Si3 to MoSi2 reduces the average grain size, which increases the grain boundary area. The reduction in the grain size is generally accompanied by acceleration of diffusion speed of oxygen and promotion of material oxidation. | Yan Jianhui Zhang Houan Tang Siwen Li Yimin | 2006 | Journal of Rare Earths2006，24，5： | 1 |

| 16 | Physical conversion and superposition of optical skyrmion topologies显示文摘Optical skyrmions are quasiparticles with nontrivial topological textures that have significant potential in optical information processing,transmission,and storage.Here,we theoretically and experimentally achieve the conversion of optical skyrmions among Néel,Bloch,intermediate skyrmions,and bimerons by polarization devices,where the fusion and annihilation of optical skyrmions are demonstrated accordingly.By analyzing the polarization pattern in Poincarébeams,we reveal the skyrmion topology dependence on the device,which provides a pathway for the study of skyrmion interactions.A vectorial optical field generator is implemented to realize the conversion and superposition experimentally,and the results are in good agreement with the theoretical predictions.These results enhance our comprehension of optical topological quasiparticles,which could have a significant impact on the transfer,storage,and communication of optical information. | HOUAN TENG JINZHAN ZHONG JIAN CHEN XINRUI LEI QIWEN ZHAN | 2023 | Photonics Research2023，11，12： | 0 |
| 17 | Performance enhancement and active sites identification of Cu-Cd bimetallic oxide derived catalysts for electrochemical CO_(2)reduction显示文摘The development of earth-abundant electrocatalysts with high performance for electrochemical CO_(2)reduction(ECR)is of great significance.Cu-based catalysts have been widely investigated for ECR due to their unique ability to generate various carbonaceous products,but directing selectivity toward one certain product and identifying the real active sites during ECR are still full of challenge.Here,after the incorporation of CdO into CuO,the Cu_(0.5)Cd_(0.5)-O catalyst achieves a 10.3-fold enhancement for CO selectivity in comparison with CuO,and a CO faradic efficiency nearly 90%with a current density around20 mA cm^(-2)could maintain at least 60 h.Interestingly,a wide CO/H_(2)ratio(0.07-10)is reached on Cu_(x)Cd_(1-x)-O catalysts by varying the Cu/Cd ratio,demonstrating the potential of syngas production using such catalysts.The results of ex situ XRD,XPS,and in situ Raman reveal that the real active sites of Cu_(0.5)Cd_(0.5)-O catalysts for CO production during ECR reaction are the reconstructed mixed phases of CuCd alloy and CdCO_(3).In situ FTIR and theoretical calculations further implicate the presence of Cd related species promotes the CO desorption and inhibits the H_(2)evolution,thus leading to an enhanced CO generation. | Cai Wang Xin Hu Bairong Chen Houan Ren Xiaoyu Wang Yilin Zhang Xinyu Chen Yuping Liu Qingxin Guan Wei Li | 2024 | Journal of Energy Chemistry2024，91，4： | 0 |
