Size-exclusion chromatography small-angle X-ray scattering of water soluble proteins on a laboratory instrument

S. Bucciarelli, S. R. Midtgaard, M. Nors Pedersen, S. Skou, L. Arleth and B. Vestergaard

Coupling of size-exclusion chromatography with biological solution small-angle X-ray scattering (SEC-SAXS) on dedicated synchrotron beamlines enables structural analysis of challenging samples such as labile proteins and low-affinity complexes...

Scalable, anisotropic transparent paper directly from wood for light management in solar cells

Jia, Chao; Li, Tian; Chen, Chaoji; Dai, Jiaqi; Kierzewski, Iain Michael; Song, Jianwei; Li, Yiju; Yang, Chunpeng; Wang, Chengwei; Hu, Liangbing

The growing demand for flexible electronics and solar energy conversion devices has fueled a search for high-quality paper-based materials with excellent mechanical flexibility and optical properties such as high transparency and haze. Despite the tremendous efforts have been dedicated to developing paper-based materials with high transparency or high haze, challenges…

High molecular weight poly(butylene succinate-co-furandicarboxylate) with 10mol% of BF unit: Synthesis, crystallization-melting behavior and mechanical properties

Peng, Shuangbao; Bu, Zhiyang; Wu, Linbo; Li, Bo-Geng; Dubois, Philippe

In this study, high molecular weight poly(butylene succinate-co-furandicarboxylate) with 10mol% of butylene furandicarboxylate unit (PBSF10) was synthesized and its crystal structure and crystallization-melting behaviors were investigated by means of WAXD, SAXS, DSC and POM. The tensile properties were also assessed. The crystal structure of PBSF10 is found to be the…

Rheological Link Between Polymer Melts with a High Molecular Weight Tail and Enhanced Formation of Shish-Kebabs

Wingstrand, Sara L.; Shen, Bo; Kornfield, Julie A.; Mortensen, Kell; Parisi, Daniele; Vlassopoulos, Dimitris; Hassager, Ole

Presence of an ultra high molecular weight (UHMw) fraction in flowing polymer melts is known to facilitate formation of oriented crystalline structures significantly. The UHMw fraction manifests itself as a minor tail in the molar mass distribution and is hardly detectable in the canonical characterization methods. In this study, alternatively,…

Precursor non-stoichiometry to enable improved CH3NH3PbBr3 nanocrystal LED performance

Chandran, Bevita K.; Veldhuis, Sjoerd A.; Chin, Xin Yu; Bruno, Annalisa; Yantara, Natalia; Chen, Xiaodong; Mhaisalkar, Subodh

High photoluminescence quantum yields and narrow emission wavelengths, combined with low temperature solution processing, make CH3NH3PbBr3 nanocrystals (NCs) favorable candidates for light-emitting applications. Herein, we describe the synthesis of CH3NH3PbBr3 NC inks by a convenient room-temperature ligand assisted reprecipitation protocol. We further investigate the effect of modulation of the…

Inter-fibrillar tie chains determined critical stress of large strain cavitation in tensile stretched isotactic polypropylene

Lu, Ying; Lyu, Dong; Xiong, Bijin; Chen, Ran; Men, Yongfeng

Isotactic polypropylene (iPP) samples with pure mesophase, pure α modification, and coexistence of both phases were used to investigate the sudden stress whitening triggered at large strain during stretching. This whitening was caused by the cavities generated in the highly oriented amorphous network. The critical stresses of such cavitation-induced whitening…

Polymer-Grafted Nanoparticle Membranes with Controllable Free Volume

Bilchak, Connor R.; Buenning, Eileen; Asai, Makoto; Zhang, Kai; Durning, Christopher J.; Kumar, Sanat K.; Huang, Yucheng; Benicewicz, Brian C.; Gidley, David W.; Cheng, Shiwang; Sokolov, Alexei P.; Minelli, Matteo; Doghieri, Ferruccio

Polymer-based membranes play a key role in several industrially important gas separation technologies, e.g., removing CO2 from natural gas, with enormous economic and environmental impact. Here, we develop a novel hybrid membrane construct comprised entirely of nanoparticles grafted with polymers. These membranes are shown to have broadly tunable separation performance…
