| 1 | Facile synthesis of high electrical conductive CoP via solid-state synthetic routes for supercapacitors显示文摘Co-P precursor was prepared by a mechanical alloying method and then is controlled to synthesis of Co P phase through an annealing method. The optimal conditions of ball milling and annealing temperature are investigated. The Co P exhibits higher electrical conductivity than graphite and cobalt oxide, showing excellent pseudocapacitive properties due its high electrical conductivity which can result in a fast electron transfer in high rate charge–discharge possess. The as-obtained Co P electrode achieves a high specific capacitance of 447.5 F/g at 1 A/g, and displays an excellent rate capability as well as good cycling stability. Besides, the asymmetric supercapacitor(ASC) based on the Co P as the positive electrode and activated carbon(AC) as the negative electrode was assembled and displayed a high rate capability(60%of the capacitance is retained when the current density increased from 1 A/g to 12 A/g), excellent cycling stability(96.7% of the initial capacitance is retained after 5000 cycles), and a superior specific energy of19 Wh/kg at a power density of 350.8 W/kg. The results suggest that the Co P electrode materials have a great potential for developing high-performance electrochemical energy storage devices. | Yumei Hu Maocheng Liu Qingqing Yang Lingbin Kong Long Kang | 2017 | Journal of Energy Chemistry2017，26，1： | 7 |
| 2 | The impact of endplate fracture on postoperative vertebral height loss and kyphotic deformity during treatment of osteoporotic vertebral compression fractures with balloon kyphoplasty显示文摘This retrospective study investigated the impact of endplate fracture on postoperative vertebral height loss and kyphotic deformity in 144 patients with osteoporotic vertebral compression fracture(OVCF),who received balloon kyphoplasty.Patients were divided into four groups:Group 1 had no superior endplate fracture,Group 2 had fractures on the anterior portion of the superior endplate,Group 3 had fractures on the posterior portion of the superior endplate,and Group 4 had complete superior endplate fractures.Anterior and middle vertebral body height,vertebral compression ratio,vertebral height loss rate,and kyphosis Cobb angle of each patient were measured and visual analogue scale(VAS) and Oswestry disability index(ODI) scores were recorded.The anterior vertebral height and kyphosis deformity of all groups significantly improved after the surgery,whereas substantial anterior vertebral height loss and increased Cobb angle were observed in all patients at the last follow-up.Although the vertebral height loss rate and the Cobb angle in Group 2,3 and 4 were larger compared with Group 1 at the last follow-up,only the vertebral height loss rate in Group 4 and the increase in the Cobb angle in Group 2 and 4 were statistically different from those in Group 1.The VAS and ODI scores in all groups measured after the surgery and at the last follow-up were significantly lower compared with preoperative scores,but there was no significant difference among these groups.Balloon kyphoplasty significantly improved vertebral fracture height and kyphosis.Vertebral height loss and increased kyphotic deformity were observed in OVCF patients with endplate fractures after the surgery.Postoperative aggravation of kyphosis was observed in Group 2.Furthermore,severe vertebral height loss and increased kyphotic deformity were confirmed in Group 4 after the surgery.Our results suggested that postoperative vertebral height loss and aggravation of kyphosis may be associated with biomechanical changes in the vertebral body caused by endplate fracture.Therefore,surgery should not only restore compressed vertebral body height and correct kyphosis,but also correct the deformity of endplate to achieve an effective treatment of OVCF patients with endplate fracture. | Qingqing Li Long Xiao Jianwei Zhang Jin Fan Wei Zhou Guoyong Yin Yongxin Ren | 2016 | The Journal of Biomedical Research2016，30，5： | 5 |
| 3 | Facile synthesis of MoS_2/graphite intercalated composite with enhanced electrochemical performance for sodium ion battery显示文摘MoS_2 is a promising anode material for sodium ion batteries owing to its two-dimensional layered structure and high specific capacity. But it still exhibits a poor cycle stability and limited rate capability for Na+storage because of its poor electrical conductivity and structural instability. In this work,MoS_2/graphite composite is fabricated by mechanically delaminated and restacked MoS_2 and graphite to form two-dimensional composite layers. The graphite sheets will improve electrical conductivity and prevent the aggregation as well as structure collapse of the MoS_2 layers during charge–discharge process.The MoS_2/graphite composite exhibits excellent Na+storage properties. It delivers a high discharge specific capacity of 358.2 m Ah/g at a current density of 100 m A/g in the first discharge process and with capacity retention of 68.1% after 800 cycles(retains 244 m Ah/g). The average discharge specific capacities retain 250.9 and 225.4 m Ah/g corresponding to the current densities of 100 and 1000 m A/g, showing excellent rate capability. The improved electrochemical performance is attributed to the improved electrical conductivity and structural stability after composition of graphite sheets. The study demonstrates a new research strategy for improving sodium ion storage properties of MoS_2. | Qingqing Yang Maocheng Liu Yumei Hu Yan Xu Lingbin Kong Long Kang | 2018 | Journal of Energy Chemistry2018，27，4： | 2 |

| 5 | Organophosphorus catalytic reaction based on reduction of phosphine oxide显示文摘The special electronic configuration of phosphorus atoms endows organophosphorus reagents with unique chemical properties,which enable them to be used to catalyze various organic reactions,such as the Wittig reaction,Staudinger reaction,Appel reaction and Mitsunobu reaction.However,the catalytic process will be accompanied by the generation of large amounts of phosphine oxide waste,resulting in the reduction of atom utilization of the reaction,and it is difficult to separate the product.Therefore,it is essential to explore a greener and more sustainable organic synthesis route based on the catalytic cycle of phosphine oxide as a model.This paper summarizes the catalytic cycle and recycling of phosphorus with or without reducing agents and reviews the related developments in recent decades:from the addition of stoichiometric strong reducing agents,to the design of ring phosphines with specific structures,to the development of new energy inputs(electrochemistry),to the addition of a series of compounds to activate the P(V)––O double bond,driving the catalytic cycle of phosphine oxide through chemical transformation.This review also points out the development potential of this field in the future,which will promote its development and progress in a greener direction. | Mengyu Pei Anqi Tian Qingqing Yang Nianyu Huang Long Wang Dongsheng Li | 2023 | Green Synthesis and Catalysis2023，4，2： | 0 |

| 7 | Targeted trace ingredients coupled with chemometric analysis for consistency evaluation of Panax notoginseng saponins injectable formulations显示文摘Evaluating the consistency of herb injectable formulations could improve their product quality and clinical safety,particularly concerning the composition and content levels of trace ingredients.Panax notoginseng Saponins Injection(PNSI),widely used in China for treating acute cardiovascular diseases,contains low-abundance(10%-25%)and trace saponins in addition to its five main constituents(notoginsenoside R1,ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1,and ginsenoside Rd).This study aimed to establish a robust analytical method and assess the variability in trace saponin levels within PNSI from different vendors and formulation types.To achieve this,a liquid chromatography-triple quadrupole mass spectrometry(LC-MS/MS)method employing multiple ions monitoring(MIM)was developed.A“post-column valve switching”strategy was implemented to eliminate highly abundant peaks(NR_(1),Rg_(1),and Re)at 26 min.A total of 51 saponins in PNSI were quantified or relatively quantified using 18 saponin standards,with digoxin as the internal standard.This study evaluated 119 batches of PNSI from seven vendors,revealing significant variability in trace saponin levels among different vendors and formulation types.These findings highlight the importance of consistent content in low-abundance and trace saponins to ensure product control and clinical safety.Standardization of these ingredients is crucial for maintaining the quality and effectiveness of PNSI in treating acute cardiovascular diseases. | ZHANG Jingxian ZHANG Zijia WANG Zhaojun ZHANG Tengqian ZHOU Yang CHEN Ming HUANG Zhanwen HE Qingqing LONG Huali HOU Jinjun WU Wanying GUO Dean | 2023 | Chinese Journal of Natural Medicines2023，21，8： | 0 |
