Science progress relies heavily on reproducibility and intersubjectivity. In science, intersubjectivity is when knowledge is communicated clearly between individuals and independently verified. It is the shared agreement and understanding of methods, results, and interpretations of scientific research that enables knowledge to be reviewed, revised, and established. Here, I focus on the reproducibility issues pertaining to the relatively young area of large-scale graphene synthesis and applications, proposing possible solutions to improve the reliability of published results and accelerate their commercialisation.
