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…

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…

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…

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…

Morphological Evolution of Tetrachlorinated Perylene Bisimides with Lengthy Alkyl Substituent Polycrystalline Thin Films during Reversible Phase Transitions

Xin, Rui; Wang, Shaojuan; Zeng, Cheng; Ji, Andong; Zhang, Jie; Ren, Zhongjie; Jiang, Wei; Wang, Zhaohui; Yan, Shouke

The phase behavior and related morphological evolution of thin films of lengthy alkyl substituted core-tetrachlorinated perylene bisimide (C18-4ClPBI), a large ?-conjugated molecule, have been studied. It is found that the C18-4ClPBI can exist in two different crystalline phases depending on temperature, which transform reversibly in heating and cooling processes. The…

Transformation from form II to form I accelerated by oriented lamellae in Polybutene-1

Chen, Jinlong; Wang, Binghua; Sun, Taicheng; Xu, Jianwei; Chen, Jingbo; Zhang, Bin

Promoting the transformation from Form II to Form I in polybutene-1 (PB-1) is deemed to be crucial and demanded for commercial applications. The mechanism of phase transition is previously described in terms of thermal or mechanical stress applied between the crystalline and amorphous regions. Here, we find that the structural…

The influence of a backbone microstructure on the side chain crystallization of a comb-like polymer is analyzed systematically using a tailor-made random versus block siloxane copolymer system. While the side alkyl chains of the random siloxane undergo a stepwise order–disorder (OD) transition to form well-ordered orthorhombic structure at low temperature,…

Inverted perovskite solar cells (PSCs) that can be entirely processed at low temperatures have attracted growing attention due to their cost-effective production. Hole-transport materials (HTMs) play an essential role in achieving efficient inverted PSCs, as they determine the effectiveness of charge extraction and recombination at interfaces. Herein, three polyfluorene copolymers…
