On the morphological behavior of ABC miktoarm stars containing poly(cis 1,4-isoprene), poly(styrene), and poly(2-vinylpyridine)

Fundamental understanding of microphase separation in ABC miktoarm copolymers is vital to access a plethora of nonconventional morphologies. Miktoarm stars based on poly(cis 1,4-isoprene) (I), poly(styrene) (S), and poly(2-vinylpyridine) (V) are model systems, which allow systematic studies of the effects of composition, chemical microstructure, and temperature on the thermodynamics of…

Overcoming efficiency and stability limits in water-processing nanoparticular organic photovoltaics by minimizing microstructure defects

Xie, Chen; Heumüller, Thomas; Gruber, Wolfgang; Tang, Xiaofeng; Classen, Andrej; Schuldes, Isabel; Bidwell, Matthew; Späth, Andreas; Fink, Rainer H.; Unruh, Tobias; McCulloch, Iain; Li, Ning; Brabec, Christoph J.

Water-based semiconducting polymer nanoparticles are eco-friendly and non-toxic but their performance suffers from the surfactants. Here Xie et al. design an approach to minimize the amount of residual surfactant in these nanoparticles and make high-efficiency and stability solar…

Liquid crystal phantom for validation of microscopic diffusion anisotropy measurements on clinical MRI systems

Nilsson, Markus; Larsson, Johan; Lundberg, Dan; Szczepankiewicz, Filip; Witzel, Thomas; Westin, Carl-Fredrik; Bryskhe, Karin; Topgaard, Daniel

Purpose To develop a phantom for validating MRI pulse sequences and data processing methods to quantify microscopic diffusion anisotropy in the human brain. Methods Using a liquid crystal consisting of water, detergent, and hydrocarbon, we designed a 0.5-L spherical phantom showing the theoretically highest possible degree of microscopic anisotropy.
