Dr. Maria-Cristina POPESCU / cpopescu@icmpp.ro / leading researcher I (R4 – CS I)

Main scientific interests: 2D-COS spectroscopy and chemometric methods for the evaluation of detailed structural features at molecular level of complex systems; synthesis of bio-nanocomposite materials (based on cellulose nanocrystals, nanoclay particles and biopolymer matrices); antimicrobial nano biocomposite formulations for seed treatment and packaging films; modification and degradation of wood.
Experience in analysis and experimental techniques: structural (mid- and near infrared spectroscopy; Raman imaging; X-ray diffraction; UV/Vis spectroscopy) morphological (optical microscopy, SEM, AFM and contact angle measurements) and thermal (thermogravimetry and differential scanning calorimetry) characterization of the polymers and polymeric systems and composites, water sorption behaviours of bio-based materials and their interaction with water.
2D-COS (two dimensional correlation spectroscopy) and chemometric methods applied to different materials (like blends of polymer/liquid crystal, natural polymers or synthetic polymer/biopolymer) for elucidation of different intermolecular interactions or the order in which the materials structure is changed as a result of an external perturbation.
