| 1 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |

| 5 | Assembly of Three Scandium-containing Heteropolytungstates Based on a Building-block Synthetic Strategy显示文摘Three novel scandium-containing heteropolytungstates[Sc3(H2O)3NO(PW9O34)2]^10(1a)Scs(H2O)2(GeW6O34)2(GeW6O26)2]^12(2a)and[Sc11(W6O10)2(OH)2(H2O)16(BiW9O33)6]^27(3a)were synthesized by reactions of Sclllions with trilacunary Keggin precursors,[A-a-XW9O34]^n(X=P,Ge,n=9,10)or[B-a-BiW9O33]^9,in NaOAc/HOAc buffer solution under conventional synthetic condition,respectively.All the three compounds were characterized by means of single-crystal X-ray diffraction(XRD),Fourier transform-infrared(FTIR)spectroscopy ultraviolet-visible(UV-Vis)spectroscopy,elemental analysis,and thermogravimetric analysis.The aqueous solutior stability of the sandwich polvanion[Sc3(H2O)3(pw9O34)2]^10-was also verified by electrospray ionization mass Spectrometry(ESI-MS)due to its good solubility in water. | ZHANG Wenqi LIN Zhengguo CHI Yingnan HONG Jie YAN Li HU Changwen | 2020 | Chemical Research in Chinese Universities2020，36，6： | 0 |
| 6 | BEHAVIORAL HEARING SCREENING OF INFANTS显示文摘It is estimated that most of the deaf children have some residual hearing. If these deaf children can be identified early, fit with hearing aids early,andtrained to speak early,they may be able to join the mainstream of hearing society.There are about 1. 16 million deaf children in China,and the number is increasingby 20 to 40 thousand each year. Some objective screening methods,such as auditorybrainstem response and otoacoustic emissions, can be more expensive than usingtrained people to perform behavioral screening. A portable “Behavioral infantScreening Audiometer”was designed by the authors. This audiometer can deliver different frequency and itensity sounds to the infants. The operator judges whether theinfant’s hearing is normal by his or her behavioral response,typically a head turn.Infants from three city communities in Beijing were screened in the communityclinics. The only criterion used for screening was that the inrants be between the ageof 26 and 36 weeks old. A total of 520 inrants were screened,and 43(8.3%) of themfailed. It took an average of 3 minutes to test an infant. Follow-up otoscope,auditory brainstem response audiometry and impedance audiometry in the First ClinicalCollege of Beijing Medical University on these 43 infants showed that 6 (1.15 % ) ofthem had a hearing loss and 37 of them had normal hearing. Follow-up on abovementioned tests were also performed on 50 infants from a control group that hadPassed the initial screening. None of them had hearing loss. The sensitivity of thisbehavioral screening was 100% and the speciticity of it was 92.8%. These resultssuggest that behavioral hearing screening is suitable for infants. | Zhengguo Zhang Wuling Zhang Jianming Wang Jinsen Lin(Institute of Basic Medical Sciences,Chinese Academy of Medical SciencesSchool of Basic Medicine,Peking Union Medical CollegeBeijing 100005,China)Xiaomei Ke(First Clinical College of Beijing Medical Uni | 1998 | Chinese Journal of Biomedical Engineering(English Edition)1998，7，1： | 0 |
| 7 | Nitrogen-rich carbon nitrogen polymers for enhancing the sorption of uranyl显示文摘Nitrogen enrichment and increased nitrogen content is an effective strategy for enhancing adsorption of uranium by carbon nitride polymers.Herein,we reported the uranium absorption by using a structurally well-defined and nitrogen-rich carbon nitride polymer with C_(3)N_(5) stoichiometry for the first time.In comparison with the adsorption performance of g-C_(3)N_(4) for U(Ⅵ),the conjugation system of the material was increased by connecting the heptazine unit through the azo bridge in the structure of C_(3)N_(5),so that C_(3)N_(5) exhibited several times higher adsorption performance than that of g-C_(3)N_(4).The C_(3)N_(5) has high kinetics for uranyl ions,which can adsorb100 mg/g U(Ⅵ)in only 10 min and reach complete adsorption equilibrium in 60 min;the theoretical maximum adsorption capacity is 207 mg/g,meanwhile,the material exhibits high selectivity.The results of spectral analysis and theoretical calculations indicate that the process of uranyl ion capture by C3N5is a combination of physical and chemical adsorption,and its higher density of electronic states makes the electrostatic binding ability enhanced,which is favorable to the adsorption of uranyl ions by C_(3)N_(5).This work indicates that C_(3)N_(5) has great promise and application in the separation and enrichment of uranyl ions,and also provides a reference for the systematic investigation of the adsorption ability of nitrogenrich carbon nitrogen polymers on uranyl ions. | Zeru Wang Wenhao Li Linzhen Wu Zhuang Wang Yalan Cao Jingkai Cheng Guangyuan Chen Qian Zhao Mei Jiang Zhengguo Chen Lin Zhu Tao Duan | 2022 | Chinese Chemical Letters2022，33，7： | 0 |
