Dr. Vaseem Mohammad liked Dr. Vaseem Mohammad's blog post Copper oxide quantum dot ink for inkjet-driven digitally controlled high mobility field effect transistorsDr. Vaseem Mohammad posted a blog postCopper oxide quantum dot ink for inkjet-driven digitally controlled high mobility field effect transistors
Copper oxide (CuO) quantum dots (QDs) having a diameter of 5–8 nm were synthesized by a simple solution process. The as-synthesized QDs showed a highly crystalline monoclinic phase of CuO with a bandgap of 1.75 eV. The CuO QDs were further formulated as an ink for inkjet printing of CuO field effect transistors (FETs). The ink-jetting behavior of the as-formulated ink samples showed that the CuO concentration and digitally controlled number of over-prints are important factors for optimizing…See More

The development of a simple and reliable method for nanoparticles-based ink in an aqueous solution is still a challenge for its inkjet printing application. Herein, we demonstrate the inkjet printing of fractal-aggregated silver (Ag) electrode lines on substrates. Spherical, monodisperse Ag nanoparticles have been synthesized using silver nitrate as a precursor, ethylene glycol as a reducing agent, and polyvinyl pyrrollidone as a capping agent. As-synthesized pure Ag nanoparticles were well…See More

Welcome
Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.
There is only one important assumption: you have to be interested in nano!
