| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Analysis of output voltage on a planar insulating core transformer显示文摘Output voltage is an important performance characteristic of planar insulating core transformer (PICT).In PICT magnetic cores are insulated from their neighboring magnetic cores by solid insulating materials.Solid insulating materials can increase leakage flux.This results in a low generated voltage in secondary coils,especially on the upper stages.Connecting flux compensation capacitors to secondary coils can compensate the flux loss.Design equations to calculate the flux compensation capacitors value and relevant simulation by CST and Protel software were presented.Simulation results of an actual PICT showed that output voltage increased by 19% after being connected to flux compensation capacitors and the voltage on every stage was equally distributed.Results of simulation were consistent with the following experimental test,which revealed that flux compensation capacitors were effective. | KANG Cheng LIU Yonghao LI Deming | 2012 | Nuclear Science and Techniques2012，23，1： | 3 |
| 3 | Potential of cellulose-based materials for lithium-ion batteries(LIB)separator membranes显示文摘Lithium-ion batteries(LIB)are the dominant power sources for many consumer electronics,and they can also be large-scale power sources/energy storage devices,which can be credited to their advantages:high efficiency,high energy density,long cycling life.The separator membrane is a critical component of LIB.It is an electron insulator between the cathode and anode electrodes in order to prevent electrical short circuits,and it also functions as an ionic conductor to let ions pass freely in the charging and discharging cycles.The critical parameters to meet high quality separator membranes include:high dimensional/thermal/chemical stability,good wettability towards electrolyte,high mechanical strength,appropriate porosity and pore size distribution.Conventionally,plastic materials,such as polyolefin,are the main materials for manufacturing LIB separator membrane.However,polyolefin separator s have a number of drawbacks such as poor thermal stability and wettability.Cellulosic materials have unique properties,and can meet the quality specifications of LIB separator membranes;in addition,they are abundant,low cost,biodegradable,renewable and sustainable.Therefore,cellulose and its related materials can be promising alternatives to replace polyolefin for LIB separator membranes.In this short review,relevant literature on the topic was reviewed and further development/improvement of cellulose-based LIB separator membrane will be discussed. | Dong Cheng Xue Yang Zhibin He Yonghao Ni | 2016 | Journal of Bioresources and Bioproducts2016，1，1： | 2 |
| 4 | Subsurface reconstruction and saturation of surface bonds显示文摘Surface reconstructions and stabilization mechanisms have been great challenges for insulators. Based on accurate determination of the long-sought atomic structure of the spinel(1 1 1) surface, here we show that the surface is stabilized by an unconventional mechanism. In general, solid surfaces have unsaturated chemical bonds and are prone to atomic reconstruction to saturate them. The spinel(1 1 1) surface,however, has the surface bonds fully saturated, while the unsaturated bonds remain only in the subsurface. It undergoes a reconstruction that keeps the topmost atomic layer unchanged, but has the subsurface atoms completely rearranged. Such a reconstruction results in a perfect compensation of the surface polarity and a large reduction in the surface energy. This work provides surprising insights into the surface stability and physical and chemical behaviors of complex oxides and insulators. | Linhan Liu Yonghao Sun Zhiying Cheng Jing Zhu Rong Yu | 2018 | Science Bulletin2018，63，23： | 2 |

| 7 | Photoinduced small electron polarons generation and recombination in hematite显示文摘Polarons generally affect adversely the photochemical and photophysical properties of transition metal oxides.However,the excited-state dynamics of polarons are not fully established to date and thus require an atomistic understanding.We focus onα-Fe_(2)O_(3)with photoexcitation,electron injection,and heterovalent doping as the small polaron models,and conduct simulations of ab initio adiabatic molecular dynamics(AIMD)and nonadiabatic molecular dynamics(NA-MD).The elaborately designed AIMD simulations show that localization of electron at a single Fe site is an adiabatic and ultrafast process within sub-15 fs.Fe_(2)O_(3)doping with an electron or a Si and Ti dopant forms a localized electron polaron while photoexcitation forms localized electron and hole polarons simultaneously,leading to diverse electron–hole recombination dynamics.NA-MD simulations demonstrate that recombination of an electron polaron created by doping with a delocalized hole at the valence band maximum ofα-Fe_(2)O_(3)takes place around 5 ps,while recombination between a pair of small electron and hole polarons in photoexcited Fe_(2)O_(3)delays to about 110 ps owing to weak NA coupling and fast decoherence process.The ultrafast formation of small electron polarons inα-Fe_(2)O_(3)impedes the accumulation of delocalized holes in the valence band that directly participate in water oxidation at photoanodes.The detrimental effect can be partially circumvented in photoexcited Fe_(2)O_(3)for slowing electron–hole recombination despite polarons may retain low charge mobility.These findings provide a fundamental understanding of the excited-state dynamics of small electron polaron inα-Fe_(2)O_(3)and may help design efficient transition metal oxides photoanodes. | Cheng Cheng Yonghao Zhu Zhaohui Zhou Run Long Wei-Hai Fang | 2022 | npj Computational Materials2022，，1： | 1 |
| 8 | Nanocellulosic materials:research/production activities and applications显示文摘Nanocelluloses have emerged as novel materials and attracted significant interest from both academia and industry.Nanocelluloses can now be produced at pilot plant and pre-commercial scales,and even at commercial scales in some regions in the world.Successful commercial applications of nanocelluloses have entered commercial stages though their full potentials are yet to be developed.In this short communication,the applications of these nanomaterials are high-lighted,including high-volume applications(e.g.,paper,textiles),high-value applications(e.g.,aerogels and structure materials for aerospace),and novel/emerging applications(e.g.,organic light emitting diodes,photonic films).Close collaboration between industries and the academic world would facilitate the development of commercial markets for using nanocelluloses in existing/new areas. | Xingye An Dong Cheng Jing Shen Qingming Jia Zhibin He Linqiang Zheng Avik Khan Bo Sun Bitao Xiong Yonghao Ni | 2017 | Journal of Bioresources and Bioproducts2017，2，2： | 0 |
| 9 | Design of B/N Co-doped micro/meso porous carbon electrodes from CNF/BNNS/ZIF-8 nanocomposites for advanced supercapacitors显示文摘Boron(B)and nitrogen(N)co-doped 3D hierarchical micro/meso porous carbon(BNPC)were successfully fabricated from cellulose nanofiber(CNF)/boron nitride nanosheets(BNNS)/zinc-methylimidazolate framework-8(ZIF-8)nanocomposites prepared by 2D BNNS,ZIF-8 nanoparticles,and wheat straw based CNFs.Herein,CNF/ZIF-8 acts as versatile skeleton and imparts partial N dopant into porous carbon structure,while the introduced BNNS can help strengthen the hierarchical porous superstructure and endow abundant B/N co-dopants within BNPC matrix.The obtained BNPC electrode possesses a high specific surface area of 505.4 m2/g,high B/N co-doping content,and desirable hydrophilicity.Supercapacitors assembled with BNPC-2(B/N co-doped porous carbon with a CNF/BNNS mass ratio of 1꞉2)electrodes exhibited exceptional electrochemical performance,demonstrating high capacitance stability even after 5000 charge-discharge cycles.The devices exhibited outstanding energy density and power density,as well as the highest specific capacitance of 433.4 F/g at 1.0 A/g,when compared with other similar reports.This study proposes a facile and sustainable strategy for efficiently fabrication of rich B/N co-doped hierarchical micro/meso porous carbon electrodes from agricultural waste biomass for advanced supercapacitor performance. | Zhen Shang Xingye An Shuangxi Nie Na Li Haibing Cao Zhengbai Cheng Hongbin Liu Yonghao Ni Liqin Liu | 2023 | Journal of Bioresources and Bioproducts2023，8，3： | 0 |
