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…

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…

Regulating the phase separation of ternary organic solar cells via 3D architectured AIE molecules

Adil, Muhammad Abdullah; Zhang, Jianqi; Wang, Yuheng; Yu, Jinde; Yang, Chen; Lu, Guanghao; Wei, Zhixiang

An optimized bulk heterojunction (BHJ) interface, certifying enhanced exciton-splitting, charge separation and recombination inhibition, is vastly desired to obtain high power conversion efficiencies (PCEs). Herein, the ternary strategy has been employed to effectively modify the phase separation between the J71:ITIC blend by incorporating a 3D aggregation-induced emission (AIE) material,…

Predicting the location of weld line in microinjection-molded polyethylene via molecular orientation distribution

Liao, Tao; Zhao, Xintong; Yang, Xiao; Whiteside, Ben; Coates, Phil; Jiang, Zhiyong; Men, Yongfeng

The microstructure and molecular orientation distribution over both the length and the thickness of microinjection-molded linear low-density polyethylene with a weld line were characterized as a function of processing parameters using small-angle X-ray scattering and wide-angle X-ray diffraction techniques. The weld line was introduced via recombination of two separated melt…

Synthesis of Anthracene Conjugates of Truncated Antifreeze Protein Sequences: Effect of the End Group and Photocontrolled Dimerization on Ice Recrystallization Inhibition Activity

Graham, Ben; Fayter, Alice E. R.; Gibson, Matthew I.

Biomacromolecular antifreezes distinguish ice from water, function by binding to specific planes of ice, and could have many applications from cryobiology to aerospace where ice is a problem. In biology, antifreeze protein (AFP) activity is regulated by protein expression levels via temperature and light-regulated expression systems, but in the laboratory…

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…

Polyfluorene Copolymers as High-Performance Hole-Transport Materials for Inverted Perovskite Solar Cells

Hu, Jinlong; You, Jiang; Peng, Chang; Qiu, Shudi; He, Wenxin; Li, Chaohui; Liu, Xianhu; Mai, Yaohua; Guo, Fei

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…

How Confinement Affects the Nucleation, Crystallization, and Dielectric Relaxation of Poly(butylene succinate) and Poly(butylene adipate) Infiltrated within Nanoporous Alumina Templates

Safari, Maryam; Maiz, Jon; Shi, Guangyu; Juanes, Diana; Liu, Guoming; Wang, Dujin; Mijangos, Carmen; Alegría, Ángel; Müller, Alejandro J.

This work describes the successful melt infiltration of poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) within 70 nm diameter anodic aluminum oxide (AAO) templates. The infiltrated samples were characterized by SEM, Raman, and FTIR spectroscopy. The crystallization behaviors and crystalline structures of both polymers, bulk and confined, were analyzed by…

Strong, Water-Stable Ionic Cable from Bio-Hydrogel

Kong, Weiqing; Li, Tian; Chen, Chaoji; Chen, Gegu; Brozena, Alexandra H.; Liu, Dapeng; Liu, Yang; Wang, Chengwei; Gan, Wentao; Wang, Sha; He, Shuaiming; Hu, Liangbing

Nanofluids have attracted much attention due to their various applications in energy storage, water desalination, and ionic circuits. However, the practical applications of the existing ionic conductors are limited due to their poor mechanical strength and stability in water. Here, inspired by nature, we develop a mechanically robust and water-stable…

In-Depth Study of Coating Multimodal Porosity Using Ellipsometry Porosimetry in Desorption Scanning Mode

Loizillon, Jérôme; Baumgartner, Bettina; Sinturel, Christophe; Abbarchi, Marco; Lendl, Bernhard; Grosso, David

Ellipsometry porosimetry provides full adsorption/desorption isotherms and is among the most accurate techniques to probe porosity in thin films. Here we address a novel technique based on desorption scanning for a precise assessment of the porosity features revealing the size distribution of interconnections between the various populations of pores in…
