Biobased Colloids and Materials (BiCMat)
The "Biobased Colloids and Materials" (BiCMat) group, led by Prof. Orlando Rojas, carries out research on the fundamental and utilization aspects of renewable resources, including lignocellulose, natural proteins and other biopolymers. BiCMat works towards supporting global sustainable development.
BiCMat group maintains a state-of the-art research program and conducts multidisciplinary research between Finland and the US. Our name, BiCMat, stands for our core activities involving biobased materials at different size scales, mainly those in the colloidal domain which display large interfacial areas, including fibers (micro/nano fibers), fiber networks, particles and colloidal systems.
Some examples of materials of interest include nano/microfibrillar cellulose, cellulose nanocrystals, lignin particles and biopolymer assemblies, thin films, cellulose derivatives, enzymes and lignocellulose-based dispersions, foams, gels and aerogels.
We study the adsorption behaviors of bio-based surfactants and biopolymers at interphases and at the solid/liquid and liquid/air interfaces using techniques such as piezoelectric and surface plasmon sensing, XPS and other spectroscopic techniques, AFM and SEM imaging, light scattering, etc.
BiCMat is a part of the Department of Forest Products Technology at Aalto University (previously Helsinki University of Technology). We are also member of Academy of Finland's Centre of Excellence in Molecular Engineering of Biosynthetic Hybrid Materials (2014-2019).
BiCMat labs are located in the Otaniemi campus of Aalto University:
