| 3 | Artificial Structural Colors and Applications显示文摘Structural colors are colors generated by the interaction between incident light and nanostructures.Structural colors have been studied for decades due to their promising advantages of long-term stability and environmentally friendly properties compared with conventional pigments and dyes.Previous studies have demonstrated many artificial structural colors inspired by naturally generated colors from plants and animals.Moreover,many strategies consisting of different principles have been reported to achieve dynamically tunable structural colors.Furthermore,the artificial structural colors can have multiple functions besides decoration,such as absorbing solar energy,anti-counterfeiting,and information encryption.In the present work,we reviewed the typical artificial structural colors generated by multilayer films,photonic crystals,and metasurfaces according to the type of structures,and discussed the approaches to achieve dynamically tunable structural colors. | Zhiyi Xuan Junyu Li Qingquan Liu Fei Yi Shaowei Wang Wei Lu | 2021 | The Innovation2021，2，1： | 3 |
| 4 | Coupled Tamm plasmon polaritons induced narrow bandpass filter with ultra-wide stopband显示文摘Narrow bandpass filters(NBPFs)play important roles in optics,such as quantum communication,spectrometer,and wavelength division multiplexing.However,the stopband and restraint ability of traditional NBPFs is limited.In this article,a coupled Tamm plasmon polaritons(TPPs)induced transmission theory has been proposed to design high-efficiency NBPFs with ultra-wide deep stopbands.An NBPF at 1.55 μm has been experimentally demonstrated with full width at half maximum(FWHM)of 10 nm and stopband ranging from 0.2 to 25 μm which is 62 times wider than that of traditional ones.Furthermore,the restraint depth of the stopband reaches 0.03%,which is only 1/20 of a traditional filter with the same FWHM.Its advantage in restraining ambient light over traditional ones has also been demonstrated with an InGaAs infrared detector.It provides a very powerful way to capture specific narrowband optical signals from ultra-wide strong ambient light,especially useful for daytime quantum communications. | Qingquan Liu Xinchao Zhao Chenlu Li Xinglei Zhou Yu Chen Shaowei Wang Wei Lu | 2022 | Nano Research2022，15，5： | 2 |

| 8 | Guidelines for the Diagnosis and Treatment of Dengue in China显示文摘Dengue is the most prevalent and rapidly spreading mosquito-borne viral disease.As a dengue non-endemic country,China has experienced several dengue outbreaks in recent years.However,dengue patients in China display clinical characteristics that are distinct from those of patients in dengue-endemic countries.To standardize the diagnosis and treatment of dengue fever,the experts at the Society of Infectious Diseases,Society of Tropical Medicine and Parasitology of the Chinese Medical Association,and the Society of Emergency Medicine of China Association of Chinese Medicine have developed a guideline after reviewing the following guidelines and data:guidelines for diagnosis,treatment,prevention,and control of dengue(World Health Organization,2009);the guidelines for diagnosis and treatment of dengue(National Health and Family Planning Commission of the People’s Republic of China,2014,Edition 2);health industry standard of the People’s Republic of China“diagnosis for dengue fever(WS216-2018)”;and systemic reports on dengue.The new guideline includes eight aspects:introduction,terminology,epidemiology and prevention,etiology and pathogenesis,clinical features,diagnosis,treatment,and problems to be solved. | Fuchun Zhang Jianfeng He Jie Peng Xiaoping Tang Chengfeng Qin Hongzhou Lu Xingwang Li Qingquan Liu Hong Zhao Jifang Sheng Guiqiang Wang Society of Infectious Diseases,Society of Tropical Medicine and Parasitology,Chinese Medical Association Society of Emergency Medicine,China Association of Chinese Medicine | 2021 | Infectious Diseases & Immunity2021，1，3： | 1 |
| 9 | Contamination degree prediction of insulator surface based on exploratory factor analysis-least square support vector machine combined model显示文摘This study presents a combined model based on the exploratory factor analysis(EFA)and the least square support vector machine(LSSVM)to predict the contamination degree of insulator surface.Firstly,EFA method is utilised to reduce numerous influence factor variables of the insulator contamination into a few factor variables,which could decrease the complexity of the model.Then,regarding the above factor variables as new input variables,LSSVM model is established to predict the insulator contamination de-gree.In order to obtain the optimal predictive value,the non-dominated sorting genetic algorithm II is applied on the optimization of LSSVM model parameters.The proposed EFA-LSSVM combined model is compared with the models of LSSVM,back propa-gation neural network,and multiple linear regression on the model performance.Results indicate that the EFA-LSSVM combined model in this study effectively overcomes the shortcomings of the other three models mentioned above in computational time,pre-diction accuracy and generalization ability.Finally,the feasibility of the proposed model in predicting contamination degree of insulator surface is verified by adopting the radar map of the evaluation indexes of model performance. | Jiaxiang Sun Hongru Zhang Qingquan Li Hongshun Liu Xinbo Lu Kaining Hou | 2021 | High Voltage2021，6，2： | 0 |
| 10 | Reversing Conventional Site-Selectivity:Electrochemically Driven C(sp^(2))-H/C(sp^(3))-H Coupling with H_(2)Evolution显示文摘Sustainable and site-selective C–H functionalization is still a challenge because of the comparable properties of bonds of the same type.Here,an electrochemical C(sp^(2))–H/C(sp^(3))–H coupling with aryl iodides is reported for the first time.The C(sp^(2))–H bond outperformed the much weaker C(sp^(2))–I bond participating in C(sp^(2))–H/C(sp^(3))–H coupling.This protocol features mild reaction conditions,good functional group tolerance,and scalability.Crosscoupling products with C–I bonds are versatile moieties for further synthetic manipulation,that can undergo Suzuki,Sonogashira,Ullmann-Ma,Catellani,Heck reactions,and so on to introduce new functional groups into target molecules with good yields.Mechanistic investigations showed that the site selectivity of the reaction is enabled by an iodineassisted[3,3]-sigmatropic rearrangement,and the interaction of hypervalent iodine generated in situ with an enolate is the rate-determining step. | Xuelian Zheng Pan Peng Cheng Huang Qingquan Lu | 2023 | CCS Chemistry2023，5，5： | 0 |
| 11 | Anodic Cyclizations, Seven-Membered Rings, and the Choice of Radical Cation vs.Radical Pathways显示文摘While many steps in an oxidative cyclization reaction can be important,it is the cyclization step itself that plays the central role.If this step does not proceed well,then optimization of the rest of the sequence is futile.We report here that the key to the cyclization is channeling the reaction down the correct pathway.Some reactions require the use of a radical pathway and some require the use of a radical cation pathway.An example of each is provided along with a strategy for accessing both pathways using a common intermediate. | Robert J.Perkins Ruozhu Feng Qingquan Lu Kevin D.Moeller | 2019 | Chinese Journal of Chemistry2019，37，7： | 0 |
