Determination of the packing model of a supramolecular nanofiber via mass-per-length measurement and de novo simulation

Yao, Qingxin; Bao, Qiang; Li, Xinming; Wang, Hui; Yang, Zhenyu; Shi, Xinghua; Gao, Yuan; Xu, Bing

Herein, we report an example of using scanning transmission electron microscopy to determine the mass-per-length of supramolecular nanofibers. Together with the measurement of the diameter of nanofibers via transmission electron microscopy, we could estimate the packing density of assembling molecules along the nanofibers. A parallel unbiased de novo simulation screens…

Cavitation in Poly(4-methyl-1-pentene) during Tensile Deformation

Chen, Ran; Lu, Ying; Jiang, Zhiyong; Men, Yongfeng

The poly(4-methyl-1-pentene) sample was used to investigate the cavitation-induced stress-whitening phenomenon during stretching at different temperatures via the ultrasmall-angle X-ray scattering technique. Two modes of cavitation were found that mode I cavitation activated around yield point followed by mode II cavitation generated in highly oriented state. The critical strain for…

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…

Characterization of multi-scale structure and thermal properties of Indica rice starch with different amylose contents

Li, Zhihang; Kong, Xiangli; Zhou, Xianrong; Zhong, Kui; Zhou, Sumei; Liu, Xingxun

Fully understanding the relationship between multi-scale structure and thermal properties of rice starch is important for starch-based food processing. Multi-scale structures of Indica rice starch were studied from molecules to aggregation structure. Gel-permeation chromatography (GPC) and high-performance anion-exchange chromatography (HPAEC) both show that the amylopectin from debranched rice…

Strengthening mechanisms in Fe-Al based ferritic low-density steels

Pramanik, Sudipta; Koppoju, Suresh; Anupama, A. V.; Sahoo, Balaram; Suwas, Satyam

Low-density steels with different aluminium contents have been investigated with an aim to examine the occurrence of different strengthening mechanisms leading to its higher strength. A composition corresponding to 6.8wt% aluminium has been studied to understand the underlying strengthening mechanisms. Different factors contributing to the strengthening mechanisms have been separately…
