| 1 | Home visits in brain tumor patient: how nurse and family members cooperate in tumor patient's family self-care显示文摘Purposes:We reported the roles and functions of nurses in home visits for brain tumor patients using the family health assessment guide in the study.Methods:One patient of brain glioma was chosen as the case illustration.The nurses assessed the patients’situation,their families and living environment individually.All these factors were analyzed together.Results:The nurses then implemented their knowledge and skills to adopt different measures in different conditions,investigated the patients’health problems and carried out personalized effective actions.Conclusions:Nurses should put effort into community nursing to allow patients to live in a safe environment,to satisfy the health needs of human being and their needs for health knowledge,and enhance their self-care abilities. | Liwei Lang Zhiyue Yan Hailiang Tang | 2013 | Chinese Journal of Cancer Research2013，25，6： | 2 |
| 2 | Progress and development directions of stimulation techniques for ultra-deep oil and gas reservoirs显示文摘By reviewing the development history of stimulation techniques for deep/ultra-deep oil and gas reservoirs,the new progress in this field in China and abroad has been summed up,including deeper understanding on formation mechanisms of fracture network in deep/ultra-deep oil and gas reservoir,performance improvement of fracturing fluid materials,fine stratification of ultra-deep vertical wells,and mature staged multi-cluster fracturing technique for ultra-deep and highly deviated wells/horizontal wells.In light of the exploration and development trend of ultra-deep oil and gas reservoirs in China,the requirements and technical difficulties in ultra-deep oil and gas reservoir stimulation are discussed:(1)The research and application of integrated geological engineering technology is difficult.(2)The requirements on fracturing materials for stimulation are high.(3)It is difficult to further improve the production in vertical profile of the ultra-deep and hugely thick reservoirs.(4)The requirements on tools and supporting high-pressure equipment on the ground for stimulation are high.(5)It is difficult to achieve efficient stimulation of ultra-deep,high-temperature and high-pressure wells.(6)It is difficult to monitor directly the reservoir stimulation and evaluate the stimulation effect accurately after stimulation.In line with the complex geological characteristics of ultra-deep oil and gas reservoirs in China,seven technical development directions are proposed:(1)To establish systematic new techniques for basic research and evaluation experiments;(2)to strengthen geological research and improve the operational mechanism of integrating geological research and engineering operation;(3)to develop high-efficiency fracturing materials for ultra-deep reservoirs;(4)to research separated layer fracturing technology for ultra-deep and hugely thick reservoirs;(5)to explore fracture-control stimulation technology for ultra-deep horizontal well;(6)to develop direct monitoring technology for hydraulic fractures in ultra-deep oil and gas reservoirs;(7)to develop downhole fracturing tools with high temperature and high pressure tolerance and supporting wellhead equipment able to withstand high pressure. | LEI Qun XU Yun YANG Zhanwei CAI Bo WANG Xin ZHOU Lang LIU Huifeng XU Minjie WANG Liwei Li Shuai | 2021 | Petroleum Exploration and Development2021，48，1： | 0 |
| 3 | Vanadium oxide cathode with synergistic engineering of calcium-ion intercalation and polyaniline coating for high performance zinc-ion batteries显示文摘Vanadium oxides as cathode for zinc-ion batteries have attracted much attention because of their high theoretical capacity,flexible layered structure and abundant resources.However,cathodes are susceptible to the collapse of their layered structure and the dissolution of vanadium after repeated long cycles,which worsen their capacities and cycling stabilities.Herein,a synergistic engineering of calcium-ion intercalation and polyaniline coating was developed to achieve the superior electrochemical performance of vanadium pentoxide for zinc-ion batteries.The pre-intercalation of calcium-ion between vanadium pentoxide layers as pillars increase the crystal structure’s stability,while the polyaniline coating on the cathodes improves the conductivity and inhibits the dissolution of vanadium.This synergistic engineering enables that the battery system based-on the polyaniline coated calcium vanadate cathode to deliver a high capacity of 406.4 mAh·g^(−1)at 1 A·g^(−1),an ultralong cycle life over 6000 cycles at 10 A·g^(−1)with 93%capacity retention and high-rate capability.The vanadium oxide cathode with synergistic engineering of calcium-ion intercalation and polyaniline coating was verified to effectively improve the electrochemical performance of zinc-ion batteries. | Lin Zhang Xinghua Qin Lang Wang Zifang Zhao Liwei Mi Qiongqiong Lu | 2023 | Frontiers of Chemical Science and Engineering2023，17，9： | 0 |
