Michel Brioude defends his doctoral dissertation
On the 26th of January 2016 Michel Brioude successfully defended his doctoral dissertation entitled “Microstructuring of Cellulose Nanocrystal Films with Plasma Polymerization”. During his doctoral studies, Michel was supported by a fellowship granted from the “Barbara und Elisabeth Grammel Stiftung”. This work, performed in cooperation with the Institute of Materials Science from Mulhouse (IS2M), France, aimed at investigating the role of cellulose nanocrystals on the microstructuration of plasma thin films. This successful partnership resulted in 3 peer-reviewed publications and should continue to thrive in a follow-up doctoral project.
Dr. Hatem Abushammala receives the Leo Schörghuber Preis 2015 at the “Münchner Holzkolloquium” for his doctoral dissertation entitled “Novel Ionic Liquid-Mediated Technologies for the Extraction of Nanocellulose Directly from Wood”
Hatem Abushammala’s dissertation exemplifies the innovations made possible by bridging the traditional field of wood science with the promises of nanotechnology. Devising a facile one-pot extraction process of cellulose nanocrystals (CNCs) from wood, Abushammala’s doctoral research at the Chair of Forest Biomaterials has opened new avenues to add value to any lignocellulosic waste stream in the forest product industry. This innovation, validated by a patent application (EP1515769) and numerous peer-reviewed publications, was made possible by his systematic approach: an initial fundamental study of the impact of ionic liquids on wood swelling and viscoelasticity proved useful to screen the efficacy of these chemicals for wood softening and defibrillation (Abushammala et al. 2015a). Abushammala then ambitioned to pulp wood, hydrolyze cellulose amorphous fractions and preserve wood cellulose native crystals all at once and with only one chemical. Amazingly, he succeeded when studying in detail the potency of imidazolium acetate ionic liquid on wood (Abushammala et al. 2015b).
Hansjürg-Steinlin-Preis for Danny García
|For his doctoral thesis “Pinus pinaster (Ait.) bark tannin and its hydroxypropyl derivatives as building-blocks for bio-material design” , Dr. Danny Eugenio García Marrero was awarded the “Hansjürg-Steinlin-Preis” by the Faculty of Environment and Natural Resources . The award ceremony took place as part of the official opening of the Academic Year 2015/2016 by Rector Prof. Dr. Dr. h.c. Schiewer on Oct. 21st 2015. Dr. Garcia is one of 3 recipients from the Faculty of Environment and Natural Resources to be recognized with this award. It is also a special honor for the Chair of Forest Biomaterials to count among its doctoral graduates an awardee of the “Hansjürg-Steinlin-Preis”, since Prof. Dr. Hansjürg Steinlin was the founding director of the former Institute of Forest Utilization and Work Science (FobAwi), from which the Chair of Forest Biomaterials emerged in 2013. Dr. García is currently a scientist at the Technological Development Unit of the University of Concepción, Chile, where he continues his work on bio-based chemicals and materials. Warm congratulations to Danny from all Biomaters!|
