Green Chemicals and Adhesives from Forestry Biomass Conversion
With increasing global concern over depletion of non-renewable fossil fuel and rising price for petroleum and petroleum derived products, there is a strong interest worldwide in developing suitable technologies that can derive fuel and chemicals from renewable biomass resources, i.e. using forestry biomass as a feed stock for “bio-refinery”. Currently we are working on converting forest biomass waste residue, such as bark, as feed stock to produce bio-based green chemicals and novel adhesives for applications in building products. Meanwhile, work is also underway to develop bark based novel panel products.
Green Bio-Based Composites and Products from Renewable Forestry Resources
Wood and other bio-fibers have the advantages of having relatively high stiffness, low density, moderate cost over other glass and inorganic fibers. More importantly, they are renewable and nearly carbon neutral. Bio-fiber composites can be used to replace conventional glass fiber reinforced composites in some building and automotives applications. However, there are a number of technical challenges related to this type of composites limiting their usage in more demanding higher end structural applications. Key issues include interface incompatibility, high moisture absorption, poor dimensional stability, and other processing related problems. Over the years, we have done a number of studies to understand the relationship between composite structure and performance and to enhance the interfacial adhesion. Currently we are working on using nano-clay to improve dimensional stability and thermal stability of the bio-fiber composites and investigating the effect of composite processing conditions on fiber characteristics. Work is also underway to combine biofibers with biopolymer to develop novel green biodegradable composites.
Development of Novel Nanocellulose Crystal Based Composite Films
Recently there is a strong interest in utilizing nanocellulosic crystal materials to develop novel films and composites. The nanocellulose crystal has a very high stiffness and good aspect ratio and some unique optical characteristics. In addition, they are derived from the renewable biomass. Our group is currently working on developing novel nanocellulosic fiber based composite films with unique functionalities.
Development of Light Weight Sandwich Panels for Construction and Automotive Applications
The panel industry and secondary furniture industries that use panel products in Canada are currently facing an intensive competitive pressure from overseas. With proper engineering design and unique light weight structural features, wood fiber resources in these novel sandwich panels can be more effectively used and the performance of each component can be maximized. We are currently working on developing FEM models, which can help us identify optimum structural parameters of this type of sandwich panels for furniture and shelving applications and on developing novel prototype light weight panels for automotive applications.
Paper-based Inexpensive Sensors and Devices
Bioactive papers are high value-added fiber-based products incorporating an advanced biological functionality capable of identifying, capturing and/or inactivating a specific target analyte. We are currently working on the efficacy of using inkjet technology for developing bioactive papers and to better understand the performance of paper as bioagent immobilization support.
Heyu Chen joined Professor Yan’s group in September 2014 as a Ph.D. student. He received his Bachelor and Master’s degree in Beijing Forestry University. Now his research focuses on the production of value-added green chemical products from tree barks. The use of natural renewable resources has attracted increasing worldwide attention as the environmental crisis and its associated socio-ecological burden are becoming a great concern. Bark, a nonfood-related biomass material available in large quantities, is a promising raw material. In addition to conducting the scientific works, Heyu likes playing badminton, go hiking, and reading in his spare time.
Organic-Inorganic Hybrid composites for construction applications
Mariam joined Prof. Yan’s research group in September 2014 as a Masters student with interests in novel composite systems as sustainable alternatives in the construction industry. Hybridizing organic and inorganic materials is a new approach being explored to achieve required material properties with less material cost. With background in Materials Engineering, Mariam will focus her research on studying the material properties and behaviours of mineral wool hybrid composites.
