In this work, the application of iron ochre obtained from a river has been applied to catalytically crack methane – another potential waste product – into two useful products, hydrogen and a magnetic carbon-containing composite.
Vertical graphene nanoflake integrated films having a high density of edge planes have been used as an electrochemical platform to systematically investigate the immobilization, electrochemical oxidation kinetics and direct quantitative determination of natural DNA. Consistently, both transmission electron microscopy and atomic force microscopy observations… (More)
