Unlocking Simultaneously the Temperature and Electrochemical Windows of Aqueous Phthalocyanine Electrolytes

Huang, Zhifeng; Zhang, Peng; Gao, Xinpei; Henkensmeier, Dirk; Passerini, Stefano; Chen, Ruiyong

The change from organic solvents to aqueous solvents for safe and robust battery electrolytes is desirable for electrochemical energy storage. Thermodynamically, water has an electrochemical stability window of 1.23 V, and pure water freezes at 0 °C. Such properties clearly restrict the high-voltage applications and temperature adaptability of aqueous electrolytes.…

De-symmetrizing periodically grafted amphiphilic copolymers: design, synthesis and generation of Janus folded chains

Sarkar, Ramkrishna; Gowd, E. Bhoje; Ramakrishnan, S.

Periodically grafted amphiphilic copolymers (PGACs) were earlier shown to fold in a zigzag fashion to enable segregation of the two immiscible segments, namely the backbone and the pendant segments; crystallization of one or both segments led to the formation of a lamellar structure with the two segments located in alternate…

Multiscale Self-Assembly of a Phenyl-Flanked Diketopyrrolopyrrole Derivative: A Solution-Processable Building Block for π-Conjugated Supramolecular Polymers

Wang, Kai; Bohra, Hassan; Gonçalves, Rui A.; Bhatnagar, Harshangda; Wu, Yingjie; Wang, Xiaochen; Wang, Zheng; Wei, Xin; Lam, Yeng Ming; Wang, Mingfeng

We report a solution-processable π-conjugated molecular building block (denoted as PhDPP) consisting of a rigid and planar core of phenyl-flanked diketopyrrolopyrrole and “soft” branched alkoxy chains that endow the solubility in a variety of organic solvents. Intermolecular hydrogen bonding in PhDPP was revealed in nonpolar solvents above a threshold of…

Simultaneous SAXS-WAXS Experiments on Semi-Crystalline Polymers: Example of PA11 and Its Brill Transition

Tencé-Girault, Sylvie; Lebreton, Sylvie; Bunau, Oana; Dang, Patrick; Bargain, François

This manuscript of the special issue “Microstructural Evolution and Mechanical Behavior of Semi-Crystalline Polymers” aims to show that Small Angle X-ray Scattering (SAXS) and Wide Angle X-ray Scattering (WAXS) experiments performed simultaneously constitute a unique tool to obtain valuable information on the hierarchical structure of semi-crystalline polymers. These structural quantitative…

Unique Isodimorphism of Poly(decamethylene succinate-ran-decamethylene fumarate): Large Pseudoeutectic Region and Fantastic Crystallization/Melting Behavior

Ye, Hai-Mu; Wang, Jing; Wang, Cai-Shui; Li, Hong-Fang

Poly(decamethylene succinate-ran-decamethylene fumarate)s (PDSFs) were synthesized, and their structure and crystallization behavior were systematically studied. All polyesters possess high crystallizability irrespective of composition and display the widest pseudoeutectic region that has been reported to date. Nevertheless, both melting point– and crystallization temperature–composition…

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…

Group B Streptococcus (GBS) is a leading cause of serious bacterial neonatal infections worldwide, which provides an unmet medical need for a globally effective vaccine. The recombinant GBS fusion antigen GBS-NN contains the N-terminal regions of the GBS Rib and Alpha C proteins. It shows promising immunogenicity eliciting protective immunity…

Thermomechanical and Conductive Properties of Thiol–Ene Poly(ionic liquid) Networks Containing Backbone and Pendant Imidazolium Groups

Bratton, Abigail F.; Kim, Sung-Soo; Ellison, Christopher J.; Miller, Kevin M.

A series of covalently cross-linked poly(ionic liquid) networks were prepared using thiol–ene “click” photopolymerization. In these networks, imidazolium groups are placed in the backbone and pendant to the main chain, creating a “hybrid”-type network architecture. The pendant imidazolium groups were incorporated into the networks from monofunctional “ene” monomers that contained…
