Synthesis, Surface Functionalization of Germanium Nanoparticles, and Their Application in Polymer Hybrid Solar Cells
DownloadSpring 2020
Germanium nanoparticles (GeNPs) have immense potential in various applications, such as opto-electronics, batteries, bioimaging, etc. Germanium has a small band gap (0.67 eV in bulk), large exciton Bohr radius (~24 nm), high absorption coefficient (ca. 2.0 × 105 cm 1 at 2 eV), and high carrier...

The Synthesis of Rhodium Catalyst-Organic Frameworks for Isomerization and Continuous-Flow Hydrogenation Reactions
DownloadFall 2013
The development of immobilized asymmetric catalysts is of vital importance as it would allow for easy catalyst recovery from the reaction mixture and reuse. One strategy for immobilization involves the synthesis of insoluble polymer-supported catalysts. Most polymeric catalysts are made by...
