| 1 | A one-for-all strategy of polyimide coating layer for resolving the comprehensive issues of phosphorus anode显示文摘Phosphorus is a promising anode with high capacity (2596 mAh g^(-1)and 6075~6924 mAh cm^(-3)),low lithium-ion diffusion barrier (0.08 e V),and appropriate lithiation potential (~0.7 V vs Li+/Li).However,it faces the problems of huge volume expansion (~300%),low electronic conductivity (10^(-14)~10^(2)S cm^(-1)),soluble intermediates (lithium polyphosphides,Li_(x)Ps),degradation in air,and low thermal stability.In this work,phosphorus/carbon nanotube composites were coated with a polyimide layer,which plays the roles of a buffer layer to relieve the volume expansion of phosphorus,an obstruct layer to confine LixPs,an inert layer to prevent the degradation of phosphorus in air,a heat resistant layer to improve the thermal stability of the anode.The resulting composites (P/CNT@PI) display high capacity retention of798.1 m Ah g^(-1)after 150 cycles at 1 A g^(-1),achieving 17 times as much as the control sample (P/CNT). | Muyao Han Shaojie Zhang Yu Cao Chengyu Han Xu Li Yiming Zhang Zhanxu Yang Jie Sun | 2022 | Journal of Energy Chemistry2022，31，7： | 2 |
| 2 | Phytochemical and pharmacological progress on Syringa oblata,a traditional Mongolian medicine显示文摘Syringa oblata is a traditional Mongolian medicine mainly distributed in the Helan Mountains(the boundaries of Inner Mongolia and Ningxia,China)and the north of Yan Mountains(Aohan Qi,Inner Mongolia,China).It is clinically used to treat diseases caused by Heyi,such as heartache and heat pathogen in the heart.Phytochemical studies on S.oblata revealed the presence of iridoids,lignans,triterpenes,phenylpropanoids,phenylethanoids,and volatile components.Pharmacological investigations revealed a broad spectrum of bioactivities,such as antimicrobial,antioxidant,antiproliferative,and hepatoprotective effects.This article summarized the chemical components and pharmacological activities of S.oblata,providing a scientific rationale for its bioactive constituents,quality control,and utilization as an important medicine. | Badalahu Tai Laxinamujila Bai Ruifeng Ji Muyao Yu NAla Luqi Huang Han Zheng | 2022 | Chinese Herbal Medicines2022，14，3： | 0 |
