Tuning the photoluminescence and anisotropic structure of PEDOT

Ivanko, Iryna; Pánek, Ji?í; Svoboda, Jan; Zhigunov, Alexander; Tomšík, Elena

In the current work, we study the photoluminescence and anisotropic structure of PEDOT which is obtained in the presence of ions that perturb the water structure (ions in Hofmeister series). The water content in PEDOT has been confirmed by TGA and DSC measurements. The weight loss and heat flux together…

The role of disaccharides for protein–protein interactions – a SANS study

Olsson, Christoffer; Swenson, Jan

The disaccharide trehalose has shown outstanding anti-aggregation properties for proteins, which are highly important for the possibility to treat neurodegenerative diseases, such as Alzheimer’s and Huntington’s disease. However, the role and mechanism of trehalose for such stabilising effects are still largely unknown, partly because a direct structural picture of how…

Harnessing Heat Beyond 200 °C from Unconcentrated Sunlight with Nonevacuated Transparent Aerogels

Zhao, Lin; Bhatia, Bikram; Yang, Sungwoo; Strobach, Elise; Weinstein, Lee A.; Cooper, Thomas A.; Chen, Gang; Wang, Evelyn N.

Heat at intermediate temperatures (120-220 °C) is in significant demand in both industrial and domestic sectors for applications such as water and space heating, steam generation, sterilization, and other industrial processes. Harnessing heat from solar energy at these temperatures, however, requires costly optical and mechanical components to concentrate the dilute…

Pure PEDOT:PSS hydrogels

Lu, Baoyang; Yuk, Hyunwoo; Lin, Shaoting; Jian, Nannan; Qu, Kai; Xu, Jingkun; Zhao, Xuanhe

Hydrogels of conducting polymers provide an electrical interface with biological tissues for sensing and stimulation, but currently have compromised mechanical and electrical properties. Here, the authors show a simple method to achieve pure PEDOT:PSS hydrogels that exhibit superior mechanical and electrical properties, stability, and tunable…

Controlling Crystal Texture in Programmable Atom Equivalent Thin Films

Gabrys, Paul A.; Macfarlane, Robert J.

DNA is a powerful tool in the directed assembly of nanoparticle based superlattice materials, as the predictable nature of Watson–Crick base pairing allows DNA-grafted particles to be programmably assembled into unit cells that arise from the complete control of nanoparticle coordination environment within the lattice. However, while the local environment…

Effects of artepillin C on model membranes displaying liquid immiscibility

Pazin, W. M.; Vilanova, N.; Voets, I. K.; Soares, A. E. E.; Ito, A. S.

It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. To test this hypothesis, we investigated the effects of the major compound of green propolis, artepillin C,…

Sulfo-Phenylated Polyphenylenes Containing Sterically Hindered Pyridines

Xu, Shaoyi; Adamski, Michael; Killer, Miho; Schibli, Eric M.; Frisken, Barbara J.; Holdcroft, Steven

We systematically investigated the effect of incorporating a sterically hindered pyridyl group into a sulfo-phenylated polyphenylene to control the polymer’s physicochemical properties through acid–base interactions. Homopolymers with similar molecular weights and comparable structures that vary by only one atom (N– vs C?) per repeat unit along the polymer chain were…
