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…

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…

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…

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…

Preparation, Structure, and Properties of an Isotactic Polypropylene Film with Ultrahigh Content, Ordered, and Continuous ?-Transcrystallinity

Liang, Guixue; Yang, Shuo; Li, Jiang; Guo, Shaoyun

?-Transcrystallinity (?-TC) of polypropylene (PP) is a novel kind of crystal that is of significant importance. Owing to the low content, discontinuity, and random distribution of ?-TC obtained by traditional methods, there has not been significant research on this particular crystal. Thus, its formation mechanism and growth law remain unclear…

Layered Ruddlesden–Popper (RP) phase (2D) halide perovskites have attracted tremendous attention due to the wide tunability on their optoelectronic properties and excellent robustness in photovoltaic devices. However, charge extraction/transport and ultimate power conversion efficiency (PCE) in 2D perovskite solar cells (PSCs) are still limited by the non-eliminable quantum well effect.…

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…
