Jiuke Mu,Gang Wang,Hongping Yan,Huayu Li,Xuemin Wang,Enlai Gao,Hou Chengyi,Anh Thi Cam Pham,Lianjun Wu,Qinghong Zhang,Yaogang Li,Zhi Ping Xu,Yang Guo,Elsa Reichmanis,Hongzhi Wang,Meifang Zhu +15 more
TL;DR: An ambient-driven actuator that takes advantage of inherent nanoscale molecular channels within a commercial perfluorosulfonic acid ionomer (PFSA) film, fabricated by simple solution processing to realize a rapid response, self-adaptive, and exceptionally stable actuation.
Journal ArticleDOI
A Wide Band Gap Polymer with a Deep Highest Occupied Molecular Orbital Level Enables 14.2% Efficiency in Polymer Solar Cells.
Sunsun Li,Long Ye,Wenchao Zhao,Hongping Yan,Bei Yang,Delong Liu,Wanning Li,Harald Ade,Jianhui Hou +8 more
TL;DR: A new benzodithiophene unit is developed and subtle side-chain modulation of the ester greatly influences the aggregation effects and molecular packing of polymer PDTB-EF-T, demonstrating the great potential of the DTBDT-EF unit for future organic photovoltaic applications.
Journal ArticleDOI
Soft x-ray scattering facility at the Advanced Light Source with real-time data processing and analysis.
Eliot Gann,Anthony Young,Brian Collins,Hongping Yan,J. Nasiatka,Howard A. Padmore,Harald Ade,Alexander Hexemer,Cheng Wang +8 more
TL;DR: Of special interest is the development of a higher harmonic rejection system that improves the spectral purity of the x-ray beam.
Journal ArticleDOI
Quadruple H-Bonding Cross-Linked Supramolecular Polymeric Materials as Substrates for Stretchable, Antitearing, and Self-Healable Thin Film Electrodes
Xuzhou Yan,Zhiyuan Liu,Qiuhong Zhang,Qiuhong Zhang,Jeffrey Lopez,Hui Wang,Hung-Chin Wu,Simiao Niu,Hongping Yan,Sihong Wang,Ting Lei,Junheng Li,Dianpeng Qi,Pingao Huang,Jianping Huang,Yu Zhang,Yuanyuan Wang,Guanglin Li,Jeffery B.-H. Tok,Xiaodong Chen,Zhenan Bao +20 more
TL;DR: A de novo chemical design of supramolecular polymer materials (SPMs-1-3) by condensation polymerization, consisting of soft polymeric chains and strong and reversible quadruple H-bonding cross-linkers, which produces soft, stretchable, yet tough elastomers.
Journal ArticleDOI
Polarized X-ray scattering reveals non-crystalline orientational ordering in organic films.
Brian Collins,Justin E. Cochran,Hongping Yan,Eliot Gann,C. Hub,Rainer H. Fink,Cheng Wang,Torben Schuettfort,Christopher R. McNeill,Michael L. Chabinyc,Harald Ade +10 more
TL;DR: P-SoXS reveals scattering anisotropy in amorphous domains of all-polymer organic solar cells where interfacial interactions pattern orientational alignment in the matrix phase, which probably plays an important role in the photophysics.
