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…

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…

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…

High-Performance Organic Electrochemical Transistors Based on Conjugated Polyelectrolyte Copolymers

Schmode, Philip; Ohayon, David; Reichstein, Paul M.; Savva, Achilleas; Inal, Sahika; Thelakkat, Mukundan

A new generation of polythiophene-based polyelectrolytes is reported to address fundamental issues in organic electrochemical transistors (OECTs). In such devices, the semiconductor must be able to transport and store ions and possess simultaneously a very high electronic mobility. For this, the ion-conducting 6-(thiophen-3-yl) hexane-1-sulfonate tetramethylammonium monomer (THS–TMA+) is…

Effect of processing conditions on the mechanical properties of bio-inspired mechanical gradient nanocomposites

Zhang, Yefei; Edelbrock, Alexandra N.; Rowan, Stuart J.

Photo-induced thiol-ene crosslinking of allyl-functionalized cellulose nanocrystal (CNC)/polymer nanocomposites allows access to films that mimic the water-enhanced mechanical gradient characteristics of the squid beak. These films are prepared by mixing the functionalized CNCs and polymer in a solvent before solution casting and drying. The photocrosslinking agents are then imbibed into…
