Microstructure and properties of polyacrylonitrile based carbon fibers

Lu, Junshan; Li, Weiwei; Kang, Hongliang; Feng, Libang; Xu, Jian; Liu, Ruigang

The microstructure of polyacrylonitrile (PAN)-based carbon fibers with different mechanical properties was investigated. It was found that the tensile strength of the PAN-based carbon fibers generally decrease with the increase in the modulus. The properties of PAN-based carbon fiber are mainly controlled by the microstructure and microvoids. The increase in…

Toughening anti-overswelling semicrystalline polymer hydrogels with ultra-small hydrophobic nanoparticles

Meng, Xiaohui; Wu, Teng; Qiu, Dong

Semicrystalline polymer hydrogels (SC-gels) are intrinsically electrolyte tolerant and over-swelling resistant, emerging as promising candidates for applications in solution environments. However, SC-gels with high mechanical strength are usually brittle. In the present work, by introducing ultra-small hydrophobic nanoparticles, highly-stretchable SC-gels (15 times of its original length) with…

Cell wall structure and composition is affected by light quality in tomato seedlings

Falcioni, Renan; Moriwaki, Thaise; Perez-Llorca, Marina; Munné-Bosch, Sergi; Gibin, Mariana Sversut; Sato, Francielle; Pelozo, Andressa; Pattaro, Mariana Carmona; Giacomelli, Marina Ellen; Rüggeberg, Markus; Antunes, Werner Camargos

Light affects many aspects of cell development. Tomato seedlings growing at different light qualities (white, blue, green, red, far-red) and in the dark displayed alterations in cell wall structure and composition. A strong and negative correlation was found between cell wall thickness and hypocotyl growth. Cell walls was thicker under…

Effect of Macromolecular Chain Movement and the Interchain Interaction on Crystalline Nucleation and Spherulite Growth of Polylactic Acid under High-Pressure CO2

Li, Shaojie; Chen, Taoyi; Liao, Xia; Han, Weiqiang; Yan, Zhihui; Li, Junsong; Li, Guangxian

Crystallization behavior of polylactic acid (PLA) under CO2 is meaningful due to its effect on foaming behavior during CO2 foaming, while present studies mainly concentrated on overall crystallization behavior. In this study, the effect of CO2 on nucleation and spherulite growth of PLA crystals was in situ investigated separately. During…

Reproducible Preparation of Proteopolymersomes via Sequential Polymer Film Hydration and Membrane Protein Reconstitution

Loo, Siew-Leng; Siti, Winna; Thiyagarajan, Monisha; Torres, Jaume; Wang, Rong; Hu, Xiao

Film rehydration method is commonly used for membrane protein (MP) reconstitution into block copolymer (BCP), but the lack of control in the rehydration step formed a heterogeneous population of proteopolymersomes that interferes with the characterization and performance of devices incorporating them. To improve the self-assembly of polymersomes with simultaneous MP…

Tailoring the pore size and permeability of isoporous membranes through blending with poly(ethylene glycol): Toward the balance of macro- and microphase separation

Yang, Cao-ying; Zhu, Guo-dong; Yi, Zhuan; Qiu, Ya-yu; Liu, Li-fen; Gao, Cong-jie

Isoporous membranes prepared from the combination of self-assembly and non-solvent induced phase inversion (SNIPS) were known for their asymmetric structures that were characterized with an isoporous top layer and porous/interconnected sublayer. This unique feature provides an opportunity to tailor the structure on toplayer and sublayer separately or synchronously by adjusting…

Nanofibril Organization in Silk Fiber as Inspiration for Ductile and Damage-Tolerant Fiber Design

Lin, Shihui; Ye, Chao; Zhang, Wenwen; Xu, Anchang; Chen, Shixian; Ren, Jing; Ling, Shengjie

Ductile and damage-tolerant fibers (DDTFs) are desired in aerospace engineering, mechanical engineering, and biomedical engineering because of their ability to prevent the catastrophic sudden structural/mechanical failure. However, in practice, design and fabrication of DDTFs remain a major challenge due to finite fiber size and limited processing techniques. In this regard,…

Photo-degradation of polyethylene under stress: A successive self-nucleation and annealing (SSA) study

Liu, Qiang; Liu, Shixiang; Lv, Yadong; Huang, Yajiang; Kong, Miqiu; Yang, Qi; Li, Guangxian

Successive self-nucleation and annealing (SSA) technique based on calorimetry is utilized to reveal the effect of uniaxial tensile stress on the photo-oxidation of high density polyethylene (HDPE). Stress-induced acceleratory and inhibitory effects on HDPE are confirmed by analyzing the newly formed melting peaks at low temperatures and the gradually disappeared…

Efficient Anti-solvent-free Spin-Coated and Printed Sn-Perovskite Solar Cells with Crystal-Based Precursor Solutions

He, Lintao; Gu, Hao; Liu, Xiaolong; Li, Pengwei; Dang, Yangyang; Liang, Chao; Ono, Luis K.; Qi, Yabing; Tao, Xutang

Tin-based perovskite solar cells (PSCs), with more consummate optical band gaps, lower exciton-binding energies, and higher charge-carrier mobility, have not attracted tremendous research efforts compared with the lead-based ones that have a record power conversion efficiency (PCE) of 24.2%. The major challenges for Sn-based research are significantly low open-circuit voltage,…

Physicochemical Properties of the Binary Mixtures of CuII-Containing Chelate-Based Ionic Liquids with Linear Alcohols

Zhang, Songna; Wang, Yongtao; Wang, Xinyu; Yao, Jia; Li, Haoran

Systematic measurements (densities, viscosities, conductivities) combined with small-angle X-ray scattering (SAXS) experiments were performed for binary mixtures of CuII-containing chelate-based ionic liquid (ChIL) with linear alcohols. The experimental results were explained by disruption of alcohols to ionic aggregation of the ChILs. Viscosity deviations (??) of four binary systems all show…
