Improved Illumination System of Laparoscope Using an Aspherical Lens Array

University of Arizona researchers have developed a more uniform illumination system for better medical images. The system directs outgoing rays from the fiber bundle to provide more uniform illumination, even with extended non-lambertian sources, allowing the full field of view to be fully observed with good detail. It is low cost and can be easily...

Synthesis of Highly Active Fe-N-C Catalysts Via Non-Contact Pyrolysis of Gas-Phase Iron

INV-20028 Background Hydrogen fuel cell vehicles (FCVs), based on proton exchange membrane fuel cells (PEMFCs), were commercialized in 2014. The catalysts used for the oxygen reduction reaction (ORR) in PEMFCs are Pt-alloys. The cost of automotive fuel cell systems is still high due to the high loading of Pt on the PEMFC cathode. One of the strategies...
