Photocatalytic degradation of bisphenol A induced by dense nanocavities inside aligned 2D-TiO2 nanostructures

Bakardjieva, Snejana; Fajgar, Radek; Jakubec, Ivo; Koci, Eva; Zhigunov, Alexander; Chatzisymeon, Efthalia; Davididou, Konstantina

The preparation of materials with aligned porosity in the nanometer range is of technological importance for a wide range of applications in molecular filtration, biomaterials and catalysis. Herein we present the advantages offered by cryo – lyophilisation technique as a smart and green non-standard concept to produce dense regular polyhedral…

3D Printing of Liquid Crystal Elastomeric Actuators with Spatially Programed Nematic Order

Kotikian, Arda; Truby, Ryan L.; Boley, John William; White, Timothy J.; Lewis, Jennifer A.

Liquid crystal elastomers (LCEs) are soft materials capable of large, reversible shape changes, which may find potential application as artificial muscles, soft robots, and dynamic functional architectures. Here, the design and additive manufacturing of LCE actuators (LCEAs) with spatially programed nematic order that exhibit large, reversible, and repeatable contraction with…

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

Chernyy, Sergey; Mahalik, Jyoti P.; Kumar, Rajeev; Kirkensgaard, Jacob Judas Kain; Arras, Matthias M. L.; Kim, Hyeyoung; Schulte, Lars; Ndoni, Sokol; Smith, Gregory S.; Mortensen, Kell; Sumpter, Bobby G.; Russell, Thomas P.; Almdal, Kristoffer

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…

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. Data…
