Corrosion and Materials Degradation (ISSN 2624-5558) an age-old and vexing problem continues to attract research attention, not only because it continues to cost our society very dearly but also for its bearings on application of new and critical technologies. For example, whether it is use of magnesium alloys as novel biodegradable temporary implants, or material for nuclear waste containers, desalination plants or durable electronic devices, corrosion often stands out as a non-trivial challenge. It is true that circumventing corrosion in such critical applications is technologically challenging, socially fulfilling as well as commercially attractive, but it is equally true that a durable solution calls for a disruptive approach, which in itself is a non-trivial challenge (given the age-old nature of the discipline). On the other hand, given the huge economic losses caused by corrosion, the emergence of a new material often triggers an interest in its applicability for corrosion resistance. Most recent examples include ultrathin coatings of graphene and hexa-boron nitride. Corrosion, and science and technology of its mitigation, therefore, is like an antique, old but fascinating.
