Medicine in Future and Advantages of Integrated Chinese and Western Medicine

引用

Chinese Journal of Integrative Medicine 2019年第2期25卷 87-90页

作者： ZHANG Jiang-hua wu Mi-shan WANG yue-fen JIA Ying-min LI En School of Integrated Traditional Chinese and Western Medicine Hebei Medical University Department of Calorimetry Hebei College of Traditional Chinese Medicine Department of Nephropathy Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University Department of Nephrology Shunyi BranchBeijing Hospital of Traditional Chinese Medicine

The history of medical development shows that oriental medicine, or traditional medicine, was born through medical practice during the times when science and technology were immature and underdeveloped, whereas with the development of science and technology, Western medicine, or modern medicine, was born through experimental analysis and research. With the development of medicine, the pros and cons of both medical systems become increasingly evident. How to integrate them and learn from each other will be the direction of future development of medicine. The formation and development of integrated medicine will, inevitably, usher in a new era for medicine.

Silafluorene moieties as promising building blocks for constructing wide-energy-gap host materials of blue phosphorescent organic light-emitting devices

引用

Science China Chemistry 2015年第6期58卷 993-998页

作者： Dongdong Wang Qingqing Liu yue Yu Yong wu Xinwen Zhang hua Dong Lin Ma Guijiang Zhou Bo Jiao Zhaoxin wu Runfeng Chen Department of Applied Chemistry School of Science Xi'an Jiaotong University Key Laboratory of Organic Electronics and Information Displays Institute of Advanced Materials School of Electronic and Information Engineering Nanjing University of Posts and Telecommunications Key Laboratory for Physical Electronics and Devices of the Ministry of Education School of Electronic and Information Engineering Xi'an Jiaotong University

In this article, we reported the synthesis and characterization of a novel silafluorene-based host material, 1,3-bis（5-methyl-5H- dibenzo[b,d]silol-5-yl）benzene （Me-DBSiB）, for blue phosphorescent organic light-emitting devices （PHOLEDs）. The Me- DBSiB was constructed by linking 9-methyl-9-silafluorene units to the phenyl framework through the sp3-hybridized silica atom to maintain high singlet and triplet energy, as well as to enhance thermal and photo-stability. The calculated result shows that the phenyl core does not contribute to both the highest occupied molecular orbital and lowest unoccupied molecular orbital. Wide optical energy gap of 4.1 eV was achieved. When the Me-DBSiB was used as the host and iridium （Ⅲ） bis[（4,6-difluorophenyl）pyridinato-N,C2＇]picolate （Firpic） as the guest, a maximum current efficiency was 14.8 cd/A, lower than the counterpart of 1,3-bis（9-carbazolyl）benzene （28 cd/A）. The unbalanced barrier for electron and hole injection to host layer may be responsible for low efficiency. Even so, our results show that silafluorene moieties are promising building blocks for constructing wide-energy-gap host materials.

农地利用政策的目的主要在于合理利用农地资源、提升农地利用效率。该文对大陆与台湾农地利用政策异同点进行梳理,认为两岸在政策制定的最初目标、发展核心、近年关注焦点等方面较为类似,而在农地权益演变、制度变迁方式、政策侧重点等方面存在差异,并就大陆农地政策发展趋势提出农地利用政策变革应逐步趋向"上下互动"方式,要"以提高农地利用效率"为目标,农地利用要趋向组织化、规模化及要加强农地分级利用管理等建议。
