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...

Nanopreparation for Co-Delivery of Drugs and siRNA

INV-13004 Background Overexpression of p‑glycoprotein (encoded by MDR1 gene) is often associated with multidrug-resistant cancer. This protein leads to drug resistance by the efflux of chemotherapeutic drugs from the cancerous cells. Small interfering RNA (siRNA), also known as post-transcriptional gene silencer, can suppress the expression of specific...
