Determination of the packing model of a supramolecular nanofiber via mass-per-length measurement and de novo simulation

Yao, Qingxin; Bao, Qiang; Li, Xinming; Wang, Hui; Yang, Zhenyu; Shi, Xinghua; Gao, Yuan; Xu, Bing

Herein, we report an example of using scanning transmission electron microscopy to determine the mass-per-length of supramolecular nanofibers. Together with the measurement of the diameter of nanofibers via transmission electron microscopy, we could estimate the packing density of assembling molecules along the nanofibers. A parallel unbiased de novo simulation screens…

Efficient perovskite photovoltaic devices using chemically doped PCDTBT as a hole-transport material

Wong-Stringer, Michael; Bishop, James E.; Smith, Joel A.; Mohamad, David K.; Parnell, Andrew J.; Kumar, Vikas; Rodenburg, Cornelia; Lidzey, David G.

It is shown that by chemically doping the carbazole-based conjugated polymer PCDTBT using the molecular materials TBP, LiTFSI and FK209, its conductivity can be increased by a factor of 105 times. Such doped PCDTBT films are used as a hole transport material (HTM) for standard architecture (CH(NH2)2PbI3)0.85(CH3NH3PbBr3)0.15 perovskite solar cells…

Thermomechanical and Conductive Properties of Thiol–Ene Poly(ionic liquid) Networks Containing Backbone and Pendant Imidazolium Groups

Bratton, Abigail F.; Kim, Sung-Soo; Ellison, Christopher J.; Miller, Kevin M.

A series of covalently cross-linked poly(ionic liquid) networks were prepared using thiol–ene “click” photopolymerization. In these networks, imidazolium groups are placed in the backbone and pendant to the main chain, creating a “hybrid”-type network architecture. The pendant imidazolium groups were incorporated into the networks from monofunctional “ene” monomers that contained…

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…
