Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...

What is the best substrate for exfoliating few layers of hexagonal boron nitride (hBN) using traditional scotch tape method?

Unlike graphene, it is usually very difficult to exfoliate few layers (~10 nm thick) of hBN on SiO2 substrate due to lip-lip interaction at the edges. Au substrates have been proven very useful...

I believe the official definition is 50 nm. source: Fujita M., Wakabayashi K., Nakada K. and Kusakabe K. (1996). "Peculiar Localized State at Zigzag Graphite Edge". Journal of the Physics Society Japan 65 (7): 1920

I think the classification is mostly dependent on the particular experiment you are carrying out (or planning to do so). In some of experiments a 100*50 nm sample could be a considered as a ribbon (say for a well resolver ballistic transport measurements), while in others can be regarded as infinite planes (for adsobtion of atoms, e.g.) end so on.
