Aqueous Polysulfide–Air Battery with a Mediator-Ion Solid Electrolyte and a Copper Sulfide Catalyst for Polysulfide Redox

Gross, Martha M.; Manthiram, Arumugam

Aqueous sodium polysulfide–air batteries are a promising system for enabling low-cost, high energy density, environmentally benign batteries for grid-scale deployment. However, the sluggish redox kinetics of aqueous polysulfide requires the use of a catalyst. Cobalt sulfide is a traditional catalyst with good activity and stability, but it uses expensive and…

Highly Efficient Luminescent Liquid Crystal with Aggregation-Induced Energy Transfer

Liu, Yi; You, Li Hong; Lin, Fa Xu; Fu, Kuo; Yuan, Wang Zhang; Chen, Er-Qiang; Yu, Zhen-Qiang; Tang, Ben Zhong

A luminescent liquid crystal molecule (TPEMes) with efficient solid-state emission is rationally constructed via the chemical conjugation of blue-emitting tetraphenylethene cores and luminescent mesogenic tolane moieties, which are both featured with aggregation-induced emission properties. As for this fluorophore, aggregation-induced energy transfer from the emissive tolane mesogens to the…

Configurationally Constrained Crystallization of Brush Polymers with Poly(ethylene oxide) Side Chains

Sun, Huilou; Yu, Duk Man; Shi, Shaowei; Yuan, Qingqing; Fujinami, So; Sun, Xiaoli; Wang, Dong; Russell, Thomas P.

The influence of physical confinement on the crystallization of poly(ethylene oxide) (PEO) has received much attention in past years. Here, rather than constraining the crystallization of the polymer by a physical or geometric boundaries, the influence of the constraints imposed by the chain architecture on the crystallization of the PEO…

Photoluminescence enhancement via microwave irradiation of carbon quantum dots derived from solvothermal synthesis of L-arginine

Omer, Khalid M.; Aziz, Kosar H. Hama; Salih, Yousif M.; Tofiq, Diary I.; Hassan, Aso Q.

Photoluminescence enhancement of carbon quantum dots was achieved via solvothermal synthesis followed by microwave irradiation. Nitrogen and phosphorous doped carbon quantum dots were prepared by solvothermal heating of L-arginine with phosphoric acid for 12 hours followed by microwave irradiation for 3 minutes. The photoluminescence enhancement was nearly two fold after…

Progression of the Morphology in Random Ionomers Containing Bulky Ammonium Counterions

Enokida, Joshua S.; Tanna, Vijesh A.; Winter, H. Henning; Coughlin, E. Bryan

Poly(isoprene-ran-dimethyloctylammonium styrenesulfonate) (P(I-ran-DMOASS)) copolymers with high molecular weights and dimethyloctylammonium styrenesulfonate (DMOASS) compositions ranging between 8 and 40 mol % (30 and 77 wt %) were synthesized via nitroxide-mediated polymerization. Thermal and viscoelastic characterization revealed distinct behaviors for the low (30–51 wt %) and high (56–77 wt…

Homeotropic Self-Alignment of Discotic Liquid Crystals for Nanoporous Polymer Films

Lugger, Jody A. M.; Mulder, Dirk J.; Bhattacharjee, Subham; Sijbesma, Rint P.

Nanostructured polymer films with continuous, membrane-spanning pores from polymerizable hexagonal columnar discotic liquid crystals (LCs) were fabricated. A robust alignment method was developed to obtain homeotropic alignment of columns between glass surfaces by adding a small amount of a tri(ethylene glycol) modified analogue of the mesogen as a dopant that…
