High Stiffness Cellulose Fibers from Low Molecular Weight Microcrystalline Cellulose Solutions Using DMSO as Co-Solvent with Ionic Liquid

Zhu, Chenchen; Koutsomitopoulou, Anastasia F.; Eichhorn, Stephen J.; Duijneveldt, Jeroen S. van; Richardson, Robert M.; Nigmatullin, Rinat; Potter, Kevin D.

There is a need to develop high-performance cellulose fibers as sustainable replacements for glass fibers, and as alternative precursors for carbon filaments. Traditional fiber spinning uses toxic solvents, but in this study, by using dimethyl sulfoxide (DMSO) as a co-solvent with an ionic liquid, a novel high-performance fiber with exceptional…

Structural and magnetic properties of cobalt iron disulfide (Co x Fe 1−x S 2 ) nanocrystals

Gabold, Henrik; Luan, Zhongyue; Paul, Neelima; Opel, Matthias; Müller-Buschbaum, Peter; Law, Matt; Paul, Amitesh

We report on synthesis and investigation of nanocrystalline cobalt-iron-pyrites with an emphasis on nanocrystal structure, morphology and magnetic behavior. The nanocrystals (NCs) were 5–25 nm in diameter as characterized using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). With an increase in Fe fraction, X-ray diffraction and small-angle-X-ray scattering (SAXS)…

Influence of Solvent Additive 1,8-Octanedithiol on P3HT:PCBM Solar Cells

Wang, Weijia; Song, Lin; Magerl, David; González, Daniel Moseguí; Körstgens, Volker; Philipp, Martine; Moulin, Jean-François; Müller‐Buschbaum, Peter

Processing solvent additives in polymer:fullerene bulk heterojunction systems are known as a promising method to enhance photovoltaic performance. It is generally agreed that solvent additives enable polymers to have a high degree of molecular order which increases the device performance. However, the understanding of the efficiency enhancement is not complete.…

Readily available titania nanostructuring routines based on mobility and polarity controlled phase separation of an amphiphilic diblock copolymer

Hohn, Nuri; Schlosser, Steffen J.; Bießmann, Lorenz; Grott, Sebastian; Xia, Senlin; Wang, Kun; Schwartzkopf, Matthias; Roth, Stephan V.; Müller-Buschbaum, Peter

The amphiphilic diblock copolymer polystyrene-block-polyethylene oxide is combined with sol–gel chemistry to control the structure formation of blade-coated foam-like titania thin films. The influence of evaporation time before immersion into a poor solvent bath and polarity of the poor solvent bath are studied. Resulting morphological changes are quantified by scanning…

CPAP3 proteins in the mineralized cuticle of a decapod crustacean

Abehsera, Shai; Zaccai, Shir; Mittelman, Binyamin; Glazer, Lilah; Weil, Simy; Khalaila, Isam; Davidov, Geula; Bitton, Ronit; Zarivach, Raz; Li, Shihao; Li, Fuhua; Xiang, Jianhai; Manor, Rivka; Aflalo, Eliahu D.; Sagi, Amir

The pancrustacean theory groups crustaceans and hexapods (once thought to comprise separate clades within the Arthropoda) into a single clade. A key feature common to all pancrustaceans is their chitinous exoskeleton, with a major contribution by cuticular proteins. Among these, are the CPAP3’s, a family of cuticular proteins, first identified…

Morphology of Anion-Conducting Ionenes Investigated by X-ray Scattering and Simulation

Schibli, Eric M.; Wright, Andrew G.; Holdcroft, Steven; Frisken, Barbara J.

We have studied the morphology of a novel series of benzimidazole-based ionenes, methylated poly(hexamethyl-p-terphenylbenzimidazolium) (HMT-PMBI), in halide form. Materials with anion-exchange capacities ranging from 0 to 2.5 mequiv/g were studied. X-ray scattering reveals three length scales in the materials: ion–polymer spacing (4 Å), polymer–polymer interchain spacing (6 Å), and an…

Wang, Rui; Tong, Yu; Manzi, Aurora; Wang, Kun; Fu, Zhendong; Kentzinger, Emmanuel; Feldmann, Jochen; Urban, Alexander S.; Müller‐Buschbaum, Peter; Frielinghaus, Henrich

Organic–inorganic perovskites demonstrate great potential for optical applications due to their intriguing optical and optoelectronic properties. Dedicated efforts have been carried out to understand the energy landscape and charge carrier mobilities for perovskite materials. In order to further boost these materials toward large-scale applications, an alternative “bottom-up” route for the…

Li4Ti5O12 (LTO) is regarded as a promising lithium-ion battery anode due to its stable cyclic performance and reliable operation safety. The moderate rate performance originated from the poor intrinsic electron and lithium-ion conductivities of the LTO has significantly limited its wide applications. A facile scalable synthesis of hierarchical Li4Ti5O12/C nanohybrids…

Extended LaMer Synthesis of Cobalt-Doped Ferrite

Fellows, B. D.; Sandler, S.; Livingston, J.; Fuller, K.; Nwandu, L.; Timmins, S.; Lantz, K. A.; Stefik, M.; Mefford, O. T.

Nonstoichiometric cobalt ferrite nanoparticles have drawn interest in magnetically mediated energy delivery due to their high magnetocrystalline anisotropy and their high peak loss frequency. The use of an extended LaMer synthesis allows for size control of the doped particles up to a threshold core diameter of 18 nm. Above this…
