| 1 | Zircon U–Pb and Hf isotopic study of Neoproterozoic granitic gneisses from the Alatage area, Xinjiang:constraints on the Precambrian crustal evolution in the Central Tianshan Block显示文摘The architecture and growth history of Precambrian crustal basements in the Central Tianshan Block play a key role in understanding the tectonic evolution of the Chinese Tianshan Orogenic Belt.In this study,we present precise LA-ICP-MS zircon U–Pb dating and LAMC-ICPMS zircon Hf isotopic data for two granitic gneisses from Alatage area in the Central Tianshan Block.The magmatic zircons from both samples yield similar protolith ages of 945±6 and 942±6 Ma,indicating that the early Neoproterozoic magmatism is prevailed in the Alatage area.These zircons have crustal Hf model ages of1.82–2.22 and 1.70–2.03 Ga,respectively,which are significantly older than their crystallization ages.It indicates that their parental magmas were derived from the reworking of ancient crust.However,we suggest that these Paleoproterozoic Hf model ages might result from mixing of continental materials with different ages in the Neoproterozoic crust.The inherited(detrital)zircon cores not only yield a wide age range of ca.989–1617 Ma,but also exhibit large Hf-isotope variations with Hf model ages of1.54–2.30 Ga.In particular,some 1.4–1.6 Ga zircons show high initial176Hf/177Hf ratios,consistent with those of depleted mantle,which indicates that the Mesoproterozoic event involved both reworking of older crust and generation of juvenile crust.The Central Tianshan Block has different Precambrian crustal growth history from the Tarim Craton.Therefore,it would not be a fragment of the Precambrian basement of the Tarim Craton. | Botao Huang Zhenyu He Keqing Zong Zeming Zhang | 2014 | Chinese Science Bulletin2014,59,1: | 12 |
| 2 | Theoretical study on the charge transport properties of triphenylene discogens with a phenylpropionyloxy or 3-phenylpropenoyloxy side chain显示文摘Charge transport is one of the most important properties in organic materials.Charge transport properties of triphenylene discogens with a phenylpropionyloxy or 3-phenylpropenoyloxy side chain have been investigated computationally on the basis of semi-classical Marcus theory.The results show that three triphenylene derivatives have high charge mobility.Title compounds have much better electronic mobility than the triphenylene.The triphenylenes containing 3-phenylpropenoyloxy have better hole mobility,but smaller electronic mobility than the triphenylenes with phenylpropionyloxy.For the triphenylene discogens with a phenylpropionyloxy,the longer the alkloxy chains,the better the positive charge transfer rate,but the smaller the negative charge transfer rate. | CHEN JunRong HUANG ChuRui XU BuYi LI Quan ZHAO KeQing | 2009 | Science China Chemistry2009,52,8: | 7 |
| 3 | Provenance of Central Canyon in Qiongdongnan Basin as evidenced by detrital zircon U-Pb study of Upper Miocene sandstones显示文摘Deep-water canyon systems can provide important sandstone reservoirs for deep-water oil and gas exploration in the South China Sea;however,the sedimentary provenance of the Central Canyon in the Qiongdongnan Basin remains controversial.In this work,detrital zircon grains from three drilling sandstones in the Upper Miocene Huangliu Formation in the western part of the Central Canyon were analysed by LA-ICP-MS for U-Pb ages,in order to constrain their provenance.One hundred and ninety-one zircon grains yield concordant U-Pb ages ranging from 28.6 to 3285 Ma.Most of them show oscillatory or linear zoning in CL-images and high Th/U ratios(>0.1),suggesting that they are magmatic zircons.Three major age clusters at about30 Ma(N=6),220–270 Ma(N=29),and 420–440 Ma(N=13),and five minor age clusters at 70–110 Ma(N=7),150–170 Ma(N=4),800–850 Ma(N=11),1800–2000 Ma(N=16),and 2400–2600 Ma(N=7),can be identified in the age spectrum,which are very similar to those of the Upper Miocene sandstones and modern river sands in the Red River area,but different from those of other nearby regions(e.g.,Hainan Island,the Pearl River area,and the Mekong River area)in Southeast Asia.The major age peak at about 30 Ma in our samples is consistent with the timing of tectonothermal events in the Red River Fault Zone.Therefore,we suggest that the provenance of the western part of the Central Canyon,in the Qiongdongnan Basin,was fed dominantly by the Paleo-Red River system during the Late Miocene. | CHEN Hui XIE XiNong GUO JingLiang SU Ming ZONG KeQing SHANG Fei HUANG Wei WANG Wei SHANG ZhiLei | 2015 | Science China Earth Sciences2015,58,8: | 6 |

Human brain tissue, unlike animal tissues, is an irreplaceable resource for the study of neurological diseases (1)Aimed at scientific research and education, the roles of human brain tissue repositories are to acquire brain tissue from donors, prepare, process, and preserve collected samples,provide tissue to specific eligible facilities, and determine the characteristics of each tissue sample. | Wenying Qiu Hanlin Zhang Aimin Bao Keqing Zhu Yue Huang Xiaoxin Yan Jing Zhang Chunjiu Zhong Yong Shen Jiangning Zhou Xiaoying Zheng Liwei Zhang Yousheng Shu Beisha Tang Zhenxin Zhang Gang Wang Ren Zhou Bing Sun Changlin Gong Shumin Duan Chao Ma | 2019 | Neuroscience Bulletin2019,35,2: | 6 |
| 5 | Phosphorylated TDP-43 Staging of Primary Age-Related Tauopathy显示文摘Primary age-related tauopathy(PART) is characterized by tau neurofibrillary tangles(NFTs) in the absence of amyloid plaque pathology. In the present study,we analyzed the distribution patterns of phosphorylated43-kDa TAR DNA-binding protein(pTDP-43) in the brains of patients with PART. Immunohistochemistry and immunofluorescence double-labeling in multiple brain regions was performed on brain tissues from PART,Alzheimer's disease(AD), and aging control cases. We examined the regional distribution patterns of pTDP-43 intraneuronal inclusions in PART with Braak NFT stages[ 0 and B IV, and a Thal phase of 0(no beta-amyloid present). We found four stages which indicated potentially sequential dissemination of pTDP-43 in PART. Stage I was characterized by the presence of pTDP-43 lesions in the amygdala, stage II by such lesions in the hippocampus,stage III by spread of pTDP-43 to the neocortex, and stage IV by pTDP-43 lesions in the putamen, pallidum, and insular cortex. In general, the distribution pattern of pTDP-43 pathology in PART cases was similar to the early TDP-43 stages reported in AD, but tended to be more restricted to the limbic system. However, there were some differences in the distribution patterns of pTDP-43 between PART and AD, especially in the dentate gyrus of the hippocampus. Positive correlations were found in PART between the Braak NFT stage and the pTDP-43 stage and density. | Xiaoling Zhang Bing Sun Xing Wang Hui Lu Fangjie Shao Annemieke J.M.Rozemuller Huazheng Liang Chong Liu Jiadong Chen Manli Huang Keqing Zhu | 2019 | Neuroscience Bulletin2019,35,2: | 3 |

| 12 | Organic additives in all-inorganic perovskite solar cells and modules:from moisture endurance to enhanced efficiency and operational stability显示文摘Power conversion efficiency(PCE) of perovskite solar cells(PSC) has been skyrocketed to certified 25.5% owing to their improved and tunable optoelectronic properties. Although, various strategies have been adopted to date regarding PCE and stability enhancement within PSC technology, certain instability factors(moisture, heat, light) are hindering their commercial placement. Recently, all-inorganic PSCs got hype in the photovoltaic research community after they attained PCE > 20% and due to their significant endurance against heat and light mishmashes, but there only left moisture sensitivity as the only roadblock for their industrial integration. Here, we review the recent progress of additive inclusion into allinorganic(CsPbX_(3)) PSCs to stabilize their intrinsic structure and to withstand the performance limiting factors. We start with the detailed description of chemical instability of different perovskite compositions, phase segregation, and how organic molecules and dyes help to repair the structural defects to improve the overall PCE and stability of PSCs. Moisture endurance as a result of chemical passivation through organic additives, low-dimensional inorganic PSCs to enhance device stability and scalable fabrication of CsPbX_(3) PSCs are also reviewed. The challenges of module degradation and design implications with proposed strategies and outlook are interpreted in the ending phrases of this review. | Yameen Ahmed Bilawal Khan MBilal Faheem Keqing Huang Yuanji Gao Junliang Yang | 2022 | Journal of Energy Chemistry2022,31,4: | 0 |
| 13 | Sparkling hot spots in perovskite solar cells under reverse bias显示文摘Perovskite solar cells(PSCs)are attracting much attention and are on the way to commercialization.However,some modules are subject to reverse bias in actual fields,so it is meaningful to investigate the reverse-bias behav-ior of PSCs.Herein,an in-situ temperature and current measurement technique was developed.Intriguingly,some hot spots were observed and then quickly disappeared in the reverse biased PSCs,along with the simultaneous increase in the current and local temperature.Also,the potential mechanism has been revealed and analyzed.An abnormal bulge in the perovskite film was found at the hot spot.Accordingly,the appearance and disappearance of hot spots were perfectly explained by band bending and tunneling current caused by ion accumulation.Addi-tionally,statistical analysis suggested that sparkling hot spots were related to reverse voltage and efficiencies of PSCs.The research provides a great significance for the study of PSCs under reverse bias. | Weiqi Li Keqing Huang Jianhui Chang Caiqi Hu Caoyu Long Hai Zhang Xavier Maldague Biao Liu Jianqiao Meng Yuxia Duan Junliang Yang | 2022 | ChemPhysMater2022,1,1: | 0 |
| 14 | 26.75 cm^(2) organic solar modules demonstrate a certified efficiency of 14.34%显示文摘Organic solar cells(OSCs)have been developed rapidly in past years,due to the fast evolution of wide-bandgap copoly-mer donors and low-bandgap non-fullerene acceptors[1−9].At present,the highest power conversion efficiencies(PCEs)for single-junction OSCs and tandem OSCs exceed 19%and 20%,respectively[10,11].These OSCs are typically fabricated by us-ing low-boiling-point solvent chloroform(CF)with an effect-ive area<0.1 cm^(2).The doctor-blading deposition is the most advantageous technique to fabricate OSCs with low-boiling-point solvent for upscaling lab cells to industrial-scale mod-ules[12],exhibiting simple operation,low cost,and high materi-al utilization[13−15].Herein,a typical OSC material system PM6:Y6(Fig.1(a))was used to fabricate OSCs modules via doc-tor-blading deposition in ambient condition,and the influ-ence of the ambient temperature and substrate temperature on the film quality was investigated. | Erming Feng Yunfei Han Jianhui Chang Hengyue Li Keqing Huang Lixiu Zhang Qun Luo Jidong Zhang Changqi Ma Yingping Zou Liming Ding Junliang Yang | 2022 | Journal of Semiconductors2022,43,10: | 0 |
