Enhanced Efficiency of Dye-Sensitized Solar Cells by Controlled Co-Adsorption Self-Assembly of Dyes.

Single dyes typically exhibit limited light absorption in dye-sensitized solar cells (DSSCs). Thus, cosensitization using two or more dyes to enhance light-harvesting efficiency has been explored; however, the aggregation of dyes can adversely affect electron injection capabilities. This study focused on the design and synthesis of three dyes with a common carbazole donor for DSSCs: , , and .

Ti-Mesh supported porous CoS nanosheet self-interconnected networks with high oxidation states for efficient hydrogen production via urea electrolysis.

The urea oxidation reaction (UOR) is an ideal alternative to the oxygen evolution reaction (OER) towards energy efficient hydrogen production. However developing Earth-abundant electrocatalysts for urea oxidation and hydrogen generation still remains a big challenge. Herein, porous CoS2 nanosheet self-interconnected networks with high oxidation states located on a Ti-mesh (P-CoS2/Ti) are synthesized and can act as a high activity catalyst for both the hydrogen evolution reaction (HER) and urea oxidation reaction (UOR).

Open-Cell Rigid Polyurethane Foams from Peanut Shell-Derived Polyols Prepared under Different Post-Processing Conditions.

Bio-based polyurethane materials with abundant open-cells have wide applications because of their biodegradability for addressing the issue of environmental conservation. In this work, open-cell rigid polyurethane foams (RPUFs) were prepared with bio-based polyols (BBPs) derived from the liquefaction of peanut shells under different post-processing conditions. The influences of the neutralization procedure and filtering operation for BBPs on the foaming behaviors, density, dimensional stability, water absorption, swelling ratio, compressive strength, and microstructure of RPUFs were investigated intensively.
