Factors controlling the structure of syndiotactic polystyrene upon the guest exchange and guest extraction processes

Shaiju, P.; Bhoje Gowd, E.

The role of host preparation method on the structural phase transition of syndiotactic polystyrene (sPS) after the guest exchange process has been thoroughly investigated in our previous study using a series of n-alkanes . In addition to the host preparation method, we have found that guest molecules used for the…

Ordered mesoporous carbons from lignin: a new class of biobased electrodes for supercapacitors

Herou, Servann; Ribadeneyra, Maria Crespo; Madhu, Rajesh; Araullo-Peters, Vicente; Jensen, Anders; Schlee, Philipp; Titirici, Magdalena

We report the synthesis of sustainable ordered mesoporous carbons (OMCs) produced from lignin, using the evaporation induced self-assembly (EISA) method. We demonstrated that it is possible to replace half of the phloroglucinol (a well-known carbon precursor currently not derived from bioprecursors) by hardwood organosolv lignin while obtaining a highly ordered…

Oxidation reactions in kink banded regions of UHMMPE fiber-based laminates used in body armor: A mechanistic study

Tsinas, Zois; Forster, Amanda L.; Al-Sheikhly, Mohamad

This work demonstrates the synergy between the thermo-mechanical and humidity induced degradation as well as the oxidation reactions in the kink-banded areas of ultra-high molar mass polyethylene (UHMMPE) fiber-based laminates used in body armor. For aged materials, the energy-dispersive X-ray spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR) results reveal…

Chiroptical Activity in Silver Cholate Nanostructures Induced by the Formation of Nanoparticle Assemblies

Layani, Muriel E.; Ben Moshe, Assaf; Varenik, Maxim; Regev, Oren; Zhang, Hui; Govorov, Alexander O.; Markovich, Gil

We report on an interesting mechanism of inducing chiroptical response at plasmonic silver nanoparticles (NPs) through the formation of plasmonic hot spots in small metal-NP?chiral-surfactant assemblies. Circular dichroism (CD) was measured at the surface plasmon resonance of cholate-coated silver nanostructures (AgCT) in the visible region of the spectrum. Low temperature…

Structure and ionic conductivity of liquid crystals having propylene carbonate units

Eisele, Andreas; Kyriakos, Konstantinos; Bhandary, Rajesh; Schönhoff, Monika; Papadakis, Christine M.; Rieger, Bernhard

Liquid-crystalline compounds with a perfluorinated aromatic ring as the mesogenic core and a propylene carbonate unit were prepared and mixed with lithium bis(trifluoro-methanesulfonyl)-imide (LiTFSI). The self-assembly was driven by the interaction of the polar propylene carbonate unit. Thus it is one of the few examples of liquid crystals with only…

Ion Distribution in Quaternary-Ammonium-Functionalized Aromatic Polymers: Effects on the Ionic Clustering and Conductivity of Anion-Exchange Membranes

Weiber, E. Annika; Jannasch, Patric

A series of copoly(arylene ether sulfone)s that have precisely two, three, or four quaternary ammonium (QA) groups clus- tered directly on single phenylene rings along the backbone are studied as anion-exchange membranes. The copolymers are synthesized by condensation polymerizations that involve either di-, tri-, or tetramethylhydroquinone followed by virtual- ly…

Increasing time of ignition for PS-clay nanocomposites filled with [Fe(bpy)3]2+-modified hectorite

Hausner, Josef; Fischer, Bianca; Stöter, Matthias; Edenharter, Andreas; Schmid, Jasmin; Kunz, Raphael; Rosenfeldt, Sabine; Altstädt, Volker; Breu, Josef

While previously reported polystyrene(PS)-clay nanocomposites all show a reduced time of ignition (tig) compared to the neat polymer, we observe a significant longer tig for a clay filler that has been modified with a highly temperature stable inorganic complex cation, trisbipyridine-iron(II) (2+). We compare cone data of nanocomposites filled with…
