| 1 | MoS2 Nanosheets Sensitized with Quantum Dots for Room-Temperature Gas Sensors显示文摘The Internet of things for environment monitoring requires high performance with low power-consumption gas sensors which could be easily integrated into large-scale sensor network.While semiconductor gas sensors have many advantages such as excellent sensitivity and low cost,their application is limited by their high operating temperature.Two-dimensional(2D)layered materials,typically molybdenum disulfide(MoS2)nanosheets,are emerging as promising gas-sensing materials candidates owing to their abundant edge sites and high in-plane carrier mobility.This work aims to overcome the sluggish and weak response as well as incomplete recovery of MoS2 gas sensors at room temperature by sensitizing MoS2 nanosheets with PbS quantum dots(QDs).The huge amount of surface dangling bonds of QDs enables them to be ideal receptors for gas molecules.The sensitized MoS2 gas sensor exhibited fast and recoverable response when operated at room temperature,and the limit of NO2 detection was estimated to be 94 ppb.The strategy of sensitizing 2D nanosheets with sensitive QD receptors may enhance receptor and transducer functions as well as the utility factor that determine the sensor performance,offering a powerful new degree of freedom to the surface and interface engineering of semiconductor gas sensors. | Jingyao Liu Zhixiang Hu Yuzhu Zhang HuaYao Li Naibo Gao Zhilai Tian Licheng Zhou Baohui Zhang Jiang Tang Jianbing Zhang Fei Yi Huan Liu | 2020 | Nano-Micro Letters2020，12，5： | 3 |

| 3 | Rapid authentication of different herbal medicines by heating online extraction electrospray ionization mass spectrometry显示文摘The rapid and accurate authentication of traditional Chinese medicines(TCMs)has always been a key scientific and technical problem in the field of pharmaceutical analysis.Herein,a novel heating online extraction electrospray ionization mass spectrometry(H-oEESI-MS)was developed for the rapid and direct analysis of extremely complex substances without the requirement for any sample pretreatment or pre-separation steps.The overall molecular profile and fragment structure features of various herbal medicines could be completely captured within 10–15 s,with minimal sample(<0.5 mg)and solvent consumption(<20μL for one sample).Furthermore,a rapid differentiation and authentication strategy for TCMs based on H-oEESI-MS was proposed,including metabolic profile characterization,characteristic marker screening and identification,and multivariate statistical analysis model validation.In an analysis of 52 batches of seven types of Aconitum medicinal materials,20 and 21 key compounds were screened out as the characteristic markers of raw and processed Aconitum herbal medicines,respectively,and the possible structures of all the characteristic markers were comprehensively identified based on Compound Discoverer databases.Finally,multivariate statistical analysis showed that all the different types of herbal medicines were well differentiated and identified(R^(2)X>0.87,R^(2)Y>0.91,and Q^(2)>0.72),which further verified the feasibility and reliability of this comprehensive strategy for the rapid authentication of different TCMs based on H-oEESI-MS.In summary,this rapid authentication strategy realized the ultra-high-throughput,low-cost,and standardized detection of various complex TCMs for the first time,thereby demonstrating wide applicability and value for the development of quality standards for TCMs. | Zidong Qiu Chaofa Wei Xiang Li Changjiangsheng Lai Zhilai Zhan Yan Jin Li Zhou Qingxiu Hao Jian Yang Shuanglong Wang Liping Kang Luqi Huang | 2023 | Journal of Pharmaceutical Analysis2023，13，3： | 0 |
| 4 | Research Progress of Polygonatum Germplasm Resources in China显示文摘Polygonatum is a traditional and precious Chinese medicine in China,as well as a traditional medicinal and food homologous material.It has a long history of cultivation and medicinal use.It not only has the effects of boosting qi and nourishing yin,nourishing the spleen and lungs,and tonifying the kidney,but also application value in food,health products,ornamental,cosmetics,etc.There are many varieties of Polygonatum resources all over China,which are easy to be mixed.There are three species of medicinal Polygonatum recorded in the 2015 edition of Pharmacopeia of the People s Republic of China.In order to sustainably use and fully develop Polygonatum medicinal resources,we conducted textual research on relevant data and research on the distribution of Polygonatum resources,germplasm identification,genetic diversity and breeding research,so as to provide a reference for the selection and breeding of polygonatum,artificial cultivation and the development and utilization of potential Polygonatum resources and for the solution of the contradiction between supply and demand in the Polygonatum market. | Kuoshu CUI Te XIAO Huiping LI Aaqil KHAN George BAWA Guopeng CHEN Teng PENG Bin LI Wenyu YANG Benchuan ZHENG Maoli WU Zhilai ZHAN | 2021 | Agricultural Biotechnology2021，10，5： | 0 |
