Monica Felicia Crăciun is a British-Romanian physicist who is a professor of Nanoscience at the university of Exeter.[1] Her research investigates 2D Materials for civil engineering, wearable technologies and optoelectronic devices. Craciun has pioneered the incorporation of graphene into concrete, wearable technologies and optoelectronic devices.
Craciun has developed 2D materials for optoelectronic devices, wearable technologies, civil engineering and quantum sciences. She pioneered several strategies to control the electronic properties of graphene through functionalisation (e.g. the incorporation of fluorine atoms). She worked to improve the techniques used to produce graphene, and showed that a resistive-heating cold-wall chemical vapor deposition approach was considerably faster and cheaper than typical processes. The cold-wall system is common to semiconductor manufacturing industries. Craciun's approach (so-called nanoCVD) uses a cold-wall reactor with a resistive heating stage.[4] She showed that this strategy to make graphene could enable the fabrication of a flexible transparent electronic device for a touch-based sensor technology.[5]
Craciun showed that graphene-based electronic threads could be woven in to polypropylene fibres for wearable technologies.[6][7][8]
Craciun created a novel form of concrete that was reinforced with graphene.[9] The incoporation of graphene resulted in concrete that was more water resistant and strong, as well as having a lesser environmental impact.[9]NBC News dubbed the material a "game-changer" for the construction industry.[10] She created a company, Concrene, based on this technology in 2018.[11] The first graphene-enhanced concrete came to market in 2021.[12]
