Background Electrochemical sensors are devices that use electrical signals to detect the presence or concentration of a target analyte. These sensors are widely used in a range of applications including glucose sensors, environmental monitoring, food safety testing, medical diagnostics, and industrial process control. However, the manufacturing process...

Background Solid oxide fuel cells (SOFCs) have drawn attention in recent years as an alternative power generation technology, due to their high efficiency and low emissions. The lanthanum strontium manganite (LSM)-yttria-stabilized zirconia (YSZ) cathode is widely utilized in SOFCs because of its high performance and stability. The microstructure of...

Background Graphene is a carbon-based material with exceptional versatility across a wide range of electrical, electrochemical, and biomedical technologies. Despite its many desirable properties, graphene’s 2D layered structure can hinder ion and molecule transport across its basal plane. This can be especially problematic when graphene layers...
